| 1 | Characteristics of Dried Soil Layers Under Apple Orchards of Different Ages and Their Applications in Soil Water Managements on the Loess Plateau of China显示文摘Negative soil water balance(i.e., water input < water output) can lead to soil desiccation and subsequently the occurrence of a dried soil layer(DSL). The DSLs are generally studied at a specific sampling depth(e.g., 500 cm), and the actual extent of DSLs remains unknown due to the challenge of collecting deep soil samples. To investigate the characteristics of actual DSLs under different ages of apple orchards and ascertain the optimal age of apple orchards for avoiding/controlling the formation of DSLs, soil samples were collected to a depth of 1 800 cm under apple orchards of different ages in Changwu on the Loess Plateau of China. As the ages increased, soil water content(SWC) and mean SWC in DSLs showed an overall decreasing trend, whereas while DSL thickness and the quantity of water deficit(QWD) in DSLs demonstrated an increasing trend. The DSL was the thickest(1 600 cm) under the 17-year-old orchard, the forming velocity of DSL thickness was the highest at the apple tree growth stage of 9–17 years(168 cm year-1), and the highest increasing velocity of QWD(-181 mm year-1) was also observed at this stage. The thickness of DSL was significantly correlated with growth age and root depth of apple trees(r > 0.88), whereas the QWD and mean SWC in DSLs were found to have no correlation with them. The optimal age of apple orchards for avoiding/controlling the formation of DSLs was about 9 years. This information provided pertinent references for the management of deep water resources by controlling the growth age of plants. | WANG Yunqiang SHAO Mingan LIU Zhipeng ZHANG Chencheng | 2015 | Pedosphere2015,25,4: | 18 |
| 2 | Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil. | TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li | 2017 | Pedosphere2017,27,3: | 17 |
| 3 | Effect of pre-deformation on the stress corrosion cracking susceptibility of aluminum alloy 2519显示文摘The effects of pre-deformation and strain rate on the stress corrosion cracking (SCC) behavior of aluminum alloy 2519 in air and in 3.5% NaCl water solution were investigated by means of slow strain rate tension (SSRT), scanning elec- tron microscopy (SEM), and transmission electron microscopy (TEM). The results indicate that the alloy is susceptible to SCC in 3.5% NaCl water solution and not in air. At the same pre-deformation, the alloy is more susceptible to SCC at 1.33 × 10·5 s·1 than at 6.66 × 10·5 s·1. Moreover, it is more susceptible to SCC at free pre-deformation than at 10% pre-deformation at the same strain rate. The number of θ precipitated along the grain boundaries is reduced and distributed discontinuously, at the same time, the precipitate-free zones (PFZ) become narrow and the susceptibility to stress corrosion cracking is reduced after 10% pre-deformation. | LI Huizhong ZHANG Xinming CHEN Mingan LI Yanfang LIANG Xiaopeng | 2007 | Rare Metals2007,26,4: | 15 |
| 4 | Evapotranspiration and its main controlling mechanism over the desert riparian forests in the lower Tarim River Basin显示文摘Evapotranspiration(ET) and its controlling mechanism over the desert riparian forests in arid regions are the important scientific basis for the water resources managements of the lower reaches of the inland rivers of China. Nearly three years of continuous measurements of surface ET, soil water content at different depths and groundwater table over a typical Tamarix spp. stand and a typical Populus euphratica stand were conducted in the lower reach of the Tarim River. The ET seasonal trends in the growing season were controlled by plant phenology, and ET in non-growing season was weak. The diurnal variations of ET resulting from the comprehensive effects of all atmospheric factors were significantly related with reference ET. The spatial pattern of ET was determined by vegetation LAI, more vegetation coverage, more ET amount. Groundwater is the water source of surface ET, and the soil water in shallow layers hardly took part in the water exchange in the groundwatersoil-plant-air system. The temporal processes of ET over the Tamarix stand and the Populus stand were similar, but the water consumption of the well-grown Populus euphratica was higher than that of the well-grown Tamarix spp. Further analysis indicates that plant transpiration accounts for most of the surface ET, with soil evaporation weak and negligible; groundwater table is a crucial factor influencing ET over the desert riparian forests, groundwater influences the processes and amounts of ET by controlling the growth and spatial distribution of desert riparian forests; quantifying the water stress of desert riparian forests using groundwater table is more appropriate, rather than soil water content. Based on the understanding of ET and water movements in the groundwater-soil-plant-air system, a generalized framework expressing the water cycling and its key controlling mechanism in the lower reaches of the inland rivers of China is described, and a simple model to estimate water requirements of the desert riparian forests is presented. | YUAN GuoFu LUO Yi SHAO MingAn ZHANG Pei ZHU XuChao | 2015 | Science China Earth Sciences2015,58,6: | 14 |
| 5 | Cassava:Nutrient composition and nutritive value in poultry diets显示文摘Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is,however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid(HCN). With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets. | Natalie K.Morgan Mingan Choct | 2016 | Animal Nutrition2016,,4: | 11 |
| 6 | Effects of yeast cell wall on growth performance, immune responses and intestinal short chain fatty acid concentrations of broilers in an experimental necrotic enteritis model显示文摘Subclinical necrotic enteritis(NE) causes devastating economic losses in the broiler chicken industry,especially in birds raised free of in-feed antibiotics. Prebiotics are potential alternatives to in-feed antibiotics. Yeast cell wall extract(YCW) derived from Saccharomyces cerevisiae is a prebiotic with known immune modulating effects. This study examined the effects of YCW and antibiotics(AB) during subclinical NE on broiler growth performance, intestinal lesions, humoral immune response and gut microflora metabolites. The study employed a 2 × 3 factorial arrangement of treatments. Factors were:NE challenge(yes or no) and feed additive(control, AB, or YCW). Each treatment was replicated in 8 floor pens with 15 birds per pen. Challenged birds had higher feed conversion ratio(FCR) than unchallenged birds on d 35(P < 0.05). Dietary inclusion of AB decreased FCR regardless of challenge(P < 0.05) on d 24 and 35. Inclusion of YCW reduced serum interleukin-1(IL-1) concentration in NE challenged birds(P < 0.01) and increased immunoglobulin(Ig) G(P < 0.05) and Ig M(P < 0.05) levels compared to other dietary treatments regardless of challenge. Yeast cell wall extract increased formic acid concentration in cecal contents during challenge and increased butyric acid concentration in unchallenged birds on d 16.This study indicates YCW suppressed inflammatory response, promoted generation of immunoglobulin and increased short chain fatty acid production suggesting potential benefits to bird health. | Guang-Da Xue Shu-Biao Wu Mingan Choct Robert A.Swick | 2017 | Animal Nutrition2017,,4: | 9 |
| 7 | Effect of oat hulls as a free choice feeding on broiler performance,short chain fatty acids and microflora under a mild necrotic enteritis challenge显示文摘Structure of fibre has been reported to enhance performance,intestinal function and modify the composition and quantity of the microbial population in the chicken gastrointestinal tract.It is hypothesised that insoluble fibre in oat hulls may improve gut health and reduce intestinal Clostridium perfringens number.This research assessed the effect of free choice oat hulls(OH) on performance and gut microbiota in broilers during a mild(subclinical) necrotic enteritis(NE) challenge.A total of 240 dayold male Ross 308 broiler chickens were assigned to 24 cages in a 2×2 factorial arrangement of treatments.Factors were challenge - or +; and OH - or +.On d 16,challenged broilers had lower weight gain and feed intake(P < 0.05) compared with unchallenged broilers.Ond 16,broilers given OH had lower feed intake(P < 0.05) and tended to have lower(P=0.062) feed conversion ratio(FCR) compared with those without access to OH.Broiler performance,however,was not affected by OH nor by challenge on d 24 and 35.The broilers given OH had heavier gizzards(P < 0.05) compared with those without OH at d 35 but not at d 13 or 16.Increased numbers of C.perfringens(P < 0.001) and reduced numbers(P < 0.05)of Lactobacillus and Salmonellae were observed in the caecal contents of challenged broilers on d 16.Challenged broilers had a lower concentration of caecal acetic acid(P < 0.01) compared with unchallenged broilers at d 16.The broilers given OH had lower concentrations of caecal acetic acid(P < 0.05),propionic acid(P < 0.05),and valeric acid(P < 0.01) compared with those without access to OH.An OH by challenge interaction on succinic acid concentration was observed on d 16(P < 0.05).Oat hulls elevated the caecal succinic acid concentration only in the unchallenged broilers.This study indicated a positive role of OH through improved gizzard function and increased succinic acid in the gut but its role in controlling NE was not conclusive. | Sarbast K.Kheravii Robert A.Swick Mingan Choct Shu-Biao Wu | 2018 | Animal Nutrition2018,,1: | 9 |
| 8 | Effect of arabinoxylo-oligosaccharides and arabinoxylans on net energy and nutrient utilization in broilers显示文摘Arabinoxylo-oligosaccharides(AXOS) are hydrolytic degradation products of arabinoxylans(AX) that can be fermented by the gut microbiota, thus potentially displaying prebiotic properties. This study examined the effects of AX and AXOS on net energy(NE) and nutrient utilization in broilers. Ross 308 broilers(n = 90, 30 birds per treatment) were fed wheat-soybean diets supplemented with pure AX, AXOS produced by exposing the AX to xylanase in vitro(AXOS), or AX with xylanase(AX + E) from d 10 to 21.Performance parameters were measured from d 10 to 21. On d 15, 10 birds per treatment were allocated to closed-circuit net energy chambers to assess the impact of AX and AXOS on dietary energy utilization,through assessment of both metabolisable energy(ME) and NE. Ileal and caecal digesta samples were collected on d 21 to determine the effect of AX and AXOS on ileal and total tract dry matter digestibility,ileal digestible energy, digesta pH, short chain fatty acids(SCFA) and microbiota concentration. Feed conversion ratio was numerically the lowest in birds fed the diet supplemented with AXOS, which is 1.26 compared to 1.37 and 1.30 for AX and AX + E, respectively. Ileal dry matter digestibility was higher in birds fed AXOS than those fed AX(P = 0.047). Ileal digestible energy and total tract dry matter digestibility were higher in birds fed AXOS than those fed AX or AX + E(P = 0.004 and P = 0.001,respectively). Birds fed AXOS had higher ME intake(P = 0.049) and nitrogen retention(P = 0.001) and a strong trend of higher NE(P = 0.056), NE intake(P = 0.057) and retained energy(P = 0.054) compared to those fed AX. Ileal total SCFA, lactic and formic acid concentrations were higher in birds fed AXOS than those fed AX(P = 0.011, P = 0.012 and P = 0.023, respectively). Birds fed AXOS or AX + E had higher caecal total SCFA, acetic, butyric and isovaleric acid concentrations compared to those fed AX(P = 0.001,P = 0.004, P = 0.016 and P = 0.008, respectively), and caecal propionic acid concentration was higher in birds fed AX + E than those fed AX(P = 0.050). Ileal and caecal microbiota concentrations were numerically higher and pH was lower in birds fed AXOS and AX + E than those fed AX. Results from this study indicate that feeding AXOS directly is more efficient than AXOS generation in the gastrointestinal tract, and suggest that AXOS has a potential to be an efficacious prebiotic in broiler diets. | Natalie K.Morgan Chake Keerqin Andrew Wallace Shu-Biao Wu Mingan Choct | 2019 | Animal Nutrition2019,,1: | 8 |
| 9 | Towards the control of necrotic enteritis in broiler chickens with in-feed antibiotics phasing-out worldwide显示文摘Poultry production has undergone a substantial increase compared to the livestock industries since 1970.However, the industry worldwide is now facing challenges with the removal of in-feed antibiotics completely or gradually, as the once well-controlled poultry diseases have re-emerged to cause tremendous loss of production. Necrotic enteritis(NE) is one of the most important diseases which costs the industry over two billion dollars annually. In this paper, we review the progress on the etiology of NE and its control through dietary modifications, pre-and probiotics, short chain fatty acids, and vaccination. The other likely measures resulted in the most advances in the toxin characterization are also discussed. Vaccine strategies may have greater potential for the control of NE mainly due to clearer etiology of NE having been elucidated in recent years with the identification of necrotic enteritis toxin B-like(NetB) toxin. Therefore, the use of alternatives to in-feed antibiotics with a better understanding of the relationship between nutrition and NE, and limiting exposure to infectious agents through biosecurity and vaccination, might be a tool to reduce the incidence of NE and to improve gut health in the absence of in-feed antibiotics. More importantly, the combinations of different measures may achieve greater protection of birds against the disease. Among all the alternatives investigated, prebiotics, organic acids and vaccination have shown improved gastrointestinal health and thus, have potential for the control of NE. | Shawkat A.M'Sadeq Shubiao Wu Robert A.Swick Mingan Choct | 2015 | Animal Nutrition2015,,1: | 6 |
| 10 | Modulations of genes related to gut integrity,apoptosis,and immunity underlie the beneficial effects of Bacillus amyloliquefaciens CECT 5940 in broilers fed diets with different protein levels in a necrotic enteritis challenge model显示文摘Background:The ban of in-feed antimicrobial additives has negatively affected the poultry industry by causing necrotic enteritis(NE)to emerge in the flocks.Alternatives such as Bacillus probiotics have shown to be effective on eliminating the negative effects of this disease.Two experiments were conducted to investigate the effect of Bacillus amyloliquefaciens CECT 5940(BA)in broiler chickens under NE challenge and/or fed diets with different protein levels.Methods:In both experiments,480 day-old mix-sexed Ross-308 broilers were arranged in a 2×2 factorial arrangement of treatments.In experiment 1,the factors were NE challenge(yes or no)and probiotic(yes or no).In experiment 2,the factors were dietary crude protein levels(standard or reduced)and probiotic(yes or no)and were used under NE challenge condition.Oral administration of Eimeria oocysts(day 9)followed by inoculation with Clostridium perfringens(day 14 and 15)was used to induce NE challenge.On day 16,two birds from each treatment were gavaged with fluorescein isothiocyanate-dextran(FITC-d)and blood samples were collected for gut integrity evaluation,and jejunal samples were collected for gene expression assay.Results:In experiment 1,BA supplementation decreased caspase-3(CASP3)(P<0.001)and caspase-8(CASP8)(P<0.05)and increased occludin(OCLD)(P<0.05)expression regardless of the challenge.Additionally,BA supplementation downregulated interfron-γ(IFN-γ)expression(P<0.01)and upregulated immunoglobulin-G(IgG)(P<0.01)and immunoglobulin-M(IgM)(P<0.05)only in challenged birds.In experiment 2,the expression of genes encoding mucin-2(MUC2)(P<0.001),tight junction protein-1(TJP1)(P<0.05)and OCLD(P<0.05)were upregulated by the addition of BA in the diet,regardless of the crude protein level.Further,BA supplementation downregulated INF-γ(P<0.01)and upregulated immunoglobulin-A(IgA)(P<0.05),IgM(P<0.05)and IgG(P<0.01)regardless of the crude protein level.Conclusion:These findings suggest that supplementation of BA in broiler diets can improve gut health by modulation of genes related to the mucosal barrier,tight junction,and immunity in broilers challenged by unfavourable conditions such as NE challenge. | Kosar Gharib-Naseri Juliano Cesar de Paula Dorigam Kiran Doranalli Sarbast Kheravii obert A.Swick Mingan Choct Shu-Biao Wu | 2021 | Journal of Animal Science and Biotechnology2021,12,2: | 6 |

| 13 | Pattern of non-starch polysaccharide digestion along the gut of the pig:Contribution to available energy显示文摘We investigated the pattern of non-starch polysaccharide(NSP) digestion along the gut of pigs fed two different wheats, which were offered with or without xylanase supplementation. The two wheats used were pre-characterised before the experiment on the basis of low and normal feed intake of young pigs.Wheat type significantly influenced feed intake and growth rate in the first 7 days, however, by day 14 the only significant effect of wheat type was on growth rate. Xylanase supplementation increased the growth performance of pigs fed the poor quality wheat to a level similar to those fed the normal wheat. It also increased the daily gain of pigs fed the normal wheat. Wheat type had no significant effect on the digestibility of dry matter(DM), energy, free sugars or the different fractions of NSP in the duodenum,ileum or in the faeces. The duodenal gross energy digestibility values for the low and high performance diets were -27.4 and -47.5%, respectively, and xylanase supplementation significantly increased the digestibility of energy back to positive levels. Dry matter digestibility values followed a similar pattern. In the duodenum, xylanase increased(P < 0.05) the digestibility values of both soluble and insoluble NSP,whereas in the ileum, xylanase had a significant effect only on the digestibility of the soluble NSP fraction. Xylanase did not affect free sugar digestibility. The reduction in soluble NSP level coincided with a marked reduction in the amount of fucose, a prominent component of mucosal polysaccharides. This suggests that soluble NSP substantially increase endogenous losses. The absence of differences in the digestibility of the measured NSP between the two wheat samples suggests that the structures of the NSP, rather than just their amount and solubility, are important for the anti-nutritional properties of NSP in pig diets. | David J.

| 14 | Use of Lactobacillus johnsonii in broilers challenged with Salmonella sofia显示文摘The effects of Lactobacillus johnsonii(L. johnsonii) on gut microflora, bird performance and intestinal development were assessed using 288 one-day-old Cobb broilers challenged with Salmonella sofia(S.sofia). The experiment was a 3×2 factorial design which consisted of three treatments, a negative control(NC) with no additives, a positive control(PC) containing antimicrobials(zinc-bacitracin, 50 mg/kg) and a probiotic group(Pro), and with the two factors being unchallenged or challenged with S. sofia.A probiotic preparation of L. johnsonii(10~9 cfu/chick) was administered to chicks individually by oral gavage on days 1, 3, 7 and 12. Chicks were individually challenged with S. sofia(10~7 cfu/chick) by oral gavage on d 2, 8 and 13. Results showed that the challenge itself markedly reduced(P < 0.05) bird performance and feed intake. And, transient clinical symptoms of the infection with S. sofia were observed from the second time they were challenged with S. sofia in the negative challenge groups. The novel probiotic candidate L. johnsonii reduced the number of S. sofia and Clostridium perfringens in the gut environment, and improved the birds’ colonization resistance to S. sofia. | Chen G.Olnood Sleman S.M.Beski Mingan Choct Paul A.Iji | 2015 | Animal Nutrition2015,,3: | 4 |

| 16 | Performance,litter quality and gaseous odour emissions of broilers fed phytase supplemented diets显示文摘The effect of graded levels of phytase on performance, bone characteristics, excreta/litter quality and odorant emissions was examined using 720 Ross 308 male d-old broilers. A 2 x 4 factorial arrangement of treatments was employed with 6 replicates of 15 birds per pen. Factors were: diets-positive and negative control(PC, NC); phytase-0, 500,1,000.1,500 FTU/kg. The PC was formulated to meet the 2014 Ross 308 nutrient specifications, whereas the NC was formulated with lower Ca(-1.4 g/kg), available P(-1.5 g/kg), Na(-0.3 g/kg), dLys(-0.2 g/kg) and MEn(-0.28 MJ/kg) equivalent to nutrient matrix values for 500 FTU/kg phytase in the starter,grower and finisher periods(i.e.,downspec diet). On d 24, phytase decreased FCR by 1.6, 4.3 and 4.6 points at inclusion levels of 500.1,000 and 1,500 FTU/kg, respectively(P < 0.01) across all diets. Phytase by diet interactions on BW gain were observed on d 24 and 35(P < 0.01). The effect of phytase was much more pronounced in the NC diet as compared with the PC diet.On d 24, phytase increased BW gain by 37, 55 and 68 g in the PC and 127.233 and 173 g in the NC at 500,1,000 and 1,500 FTU/kg, respectively. Diet by phytase interactions were also observed for tibia ash, litter quality and water to feed intake ratio(P < 0.01) with higher phytase effect in NC as compared with PC.Neither diet nor phytase impacted excreta moisture content on d 18 or 21(P> 0.05). Solid phase microextraction gas chromatography-mass spectrometry(SPME-GC-MS) analysis of gaseous emissions on d 39 indicated no difference in the emission of alcohols, aldehydes, ketones, volatile fatty acids and phenols between treatments(P> 0.05). The results indicate that phytase has greater benefits when formulated using nutrient matrix values as compared with adding it over the top in an already nutrient sufficient diet. The later method would be expected to increase feed costs without concomitant performance benefits. | Nishchal K.Sharma Mingan Choct Shu-Biao Wu Robert Smillie Natalie Morgan Amal S.Omar Nisha Sharma Robert A.Swick | 2016 | Animal Nutrition2016,,4: | 3 |

| 18 | Humic acid transport in saturated porous media:Influence of flow velocity and influent concentration显示文摘Understanding the transport of humic acids(HAs)in porous media can provide important and practical evidence needed for accurate prediction of organic/inorganic contaminant transport in different environmental media and interfaces.A series of column transport experiments was conducted to evaluate the transport of HA in different porous media at different flow velocities and influent HA concentrations.Low flow velocity and influent concentration were found to favor the adsorption and deposition of HA onto sand grains packed into columns and to give higher equilibrium distribution coefficients and deposition rate coefficients,which resulted in an increased fraction of HA being retained in columns.Consequently,retardation factors were increased and the transport of HA through the columns was delayed.These results suggest that the transport of HA in porous media is primarily controlled by the attachment of HA to the solid matrix.Accordingly,this attachment should be considered in studies of HA behavior in porous media. | Xiaorong Wei Mingan Shao Lina Du Robert Horton | 2014 | Journal of Environmental Sciences2014,26,12: | 3 |

| 20 | Novel probiotics: Their effects on growth performance, gut development, microbial community and activity of broiler chickens显示文摘A total of 294 one-day-old Cobb broiler chickens were used to investigate the effects of four Lactobacillus strains on gut microbial profile and production performance. The six dietary treatments, each with 7 replicates were: 1) basal diet(negative control), 2) one of four strains of Lactobacillus(tentatively identified as Lactobacillus johnsonii, Lactobacillus crispatus, Lactobacillus salivarius and an unidentified Lactobacillus sp.) and 3) basal diet with added zinc-bacitracin(ZnB, 50 mg/kg). Results showed that the addition of probiotic Lactobacillus spp. to the feed did not significantly improve weight gain, feed intake and feed conversion rate(FCR) of broiler chickens raised in cages during the 6-week experimental period,but tended to increase the number of total anaerobic bacteria in the ileum and caeca, and the number of lactic acid bacteria and lactobacilli in the caeca; and to significantly increase the small intestinal weight(jejunum and ileum). Furthermore, all 4 probiotics tended to reduce the number of Enterobacteria in the ileum, compared with the control treatments. The probiotics did not affect the p H and the concentrations of short chain fatty acids(SCFA) and lactic acid in both the ileum and caeca. | Chen G.Olnood Sleman S.M.Beski Mingan Choct Paul A.Iji | 2015 | Animal Nutrition2015,,3: | 3 |
