1提高母猪妊娠后期和哺乳期日粮能量浓度对其生产性能、仔猪活力和后代终生生长的影响(下)显示文摘人们对高产母猪的选育,导致每窝活产仔数显著增加,但是随之而来的仔猪活力和生长性能会因此降低。为了增强仔猪活力和提高生长性能,提高母猪哺乳期能量摄入越来越重要。研究旨在探索提高哺乳期母猪日粮能量(DE)浓度对母猪体重、背膘厚、乳成分及其后代仔猪活力和生长的影响。在妊娠108 d时将妊娠母猪(N=100;大白×长白)随机分配饲喂4种能量浓度日粮(消化能,DE,MJ/kg)直到再次配种:13.8(LL)、14.5(L)、15.2(H)、15.9(HH)。所有日粮均含有1.2%总赖氨酸。妊娠108 d和断奶(哺乳期第26天)时采集血样,哺乳期采集初乳(0 d)和常乳(14 d)。每天记录母猪哺乳期采食量。仔猪出生时记录每窝(总活)产仔数、仔猪初生重、宫内生长受限(IUGR)特征和肌张力。在出生时和出生后24 h记录仔猪鼓膜耳温(TEMP)。在后代猪第1、6、14、26、33、40、54、75和141日龄时称重。后代猪于断奶后(PW)饲喂标准谷物基础日粮。后代猪屠宰时(141日龄)记录胴体数据。HH母猪的哺乳期消化能摄入高于其他处理组(P<0.01)。初乳和常乳成分以及哺乳期采食量不受日粮处理影响。各处理组间的每窝产仔猪数和仔猪初生重相近。与其他处理组相比,LL母猪的后代表现出更多的IUGR特征(P<0.01),而HH母猪的后代表现出更好的肌张力(P<0.01)。与HH母猪的后代仔猪相比,LL母猪(P<0.01)和H母猪(P<0.01)的后代具有更高的24 h TEMP。H母猪断奶仔猪数高于L母猪(P<0.05)和HH母猪(P<0.01),而L母猪断奶仔猪窝重低于H母猪(P<0.05)和LL母猪(P<0.05)。断奶后仔猪生长不受日粮各处理影响。高DE日粮提高母猪能量摄入水平,但并不抑制食欲。饲喂HH日粮提高了仔猪出生时肌张力,而饲喂H日粮提高每窝断奶仔猪数。此次研究观察到仔猪活力的其他特征和断奶前窝生长性能结果互相矛盾。何颖(编译) Rooney H B O’driscoll Keelin O’doherty John V 2020猪业科学2020,37,9:5

16Effect of supplementation with n-3 polyunsaturated fatty acids and/or β-glucans on performance, feeding behaviour and immune status of Holstein Friesian bull calves during the pre-and post-weaning periods显示文摘Background: Previous research in both calves and other species has suggested n-3 polyunsaturated fatty acids(PUFA) and β-glucans may have positive effects on immune function. This experiment measured performance,behaviour, metabolite and immunological responses to pre-weaning supplementation of dairy bull calves with n-3 PUFA in the form of fish oil and β-glucans derived from seaweed extract. 44 Holstein Friesian bull calves, aged 13.7± 2.5 d and weighing 48.0 ± 5.8 kg were artificially reared using an electronic feeding system. Each calf was offered5 L(120 g/L) per day of milk replacer(MR) and assigned to one of four treatments included in the MR,(1) Control(CON);(2) 40 g n-3 PUFA per day(FO);(3) 1 g β-glucans per day(GL) and(4) 40 g n-3 PUFA per day & 1 g/d β-glucans(FOGL) in a 2 × 2 factorial design. Milk replacer and concentrate was offered from d 0–62(pre-weaning),while concentrate provision continued for a further 31 d post-weaning period. Individual daily feed intake and feeding behaviour was recorded throughout, while bodyweight and blood analyte data were collected at regular intervals.Results: Overall mean concentrate DMI from d 0–93 was 1.39, 1.27, 1.00 and 0.72 kg/d for CON, FO, GL and FOGL calves, respectively(SEM = 0.037;P < 0.0001). Calves supplemented with GL were significantly lighter(P < 0.0001) at both weaning(d 62) and turnout to pasture(d 93) than un-supplemented calves, with a similar effect(P < 0.0001)evident for calves receiving FO compared to un-supplemented contemporaries. Supplementation with GL reduced the number of unrewarded visits where milk was not consumed(P < 0.0001) while supplementation with FO increased mean drinking speed(P < 0.0001). Supplementation with GL resulted in greater concentrations of haptoglobin(P = 0.034), greater serum osmolality(P = 0.021) and lower lymphocyte levels(P = 0.027). In addition,cells from GL supplemented calves exhibited a lower response than un-supplemented contemporaries to both Phytohaemagglutinin A stimulated IFN-γ(P = 0.019) and Concanavalin A stimulated IFN-γ(P = 0.012) following in vitro challenges.Conclusions: Pre-weaning supplementation of bull calves with either n-3 PUFA or β-glucan resulted in reduced voluntary feed intake of concentrate and consequently poorer pre-weaning calf performance. There was no evidence for any beneficial effect of either supplementation strategy on calves’ immune responses.Ruairi P.McDonnell John V.O’Doherty Bernadette Earley Anne Marie Clarke David A.Kenny 2019Journal of Animal Science and Biotechnology2019,10,2:1

19The effects of dietary supplementation with mushroom or selenium enriched mushroom powders on the growth performance and intestinal health of post-weaned pigs显示文摘Background There is an urgent need to identify natural bioactive compounds that can enhance gastrointestinal health and promote pig growth performance in the absence of pharmacological levels of zinc oxide(ZnO).The objectives of this study were to:1)compare the effects of mushroom powder supplemented with inorganic selenium(inSeMP)to mushroom powder enriched with organic selenium(orgSeMP)to pharmacological levels of ZnO on growth performance and faecal scores(FS)for the first 21 d post-weaning(Period 1);and 2)compare the molecular and microbial effects of inSeMP and orgSeMP in these pigs on d 39 post-weaning(Period 2).Methods In Period 1,pigs(3 pigs/pen;8 pens/treatment)were assigned to:(1)basal diet(control);(2)basal diet+zinc oxide(ZnO)(3100 mg/kg d 1–14,1550 mg/kg d 15–21);(3)basal diet+mushroom powder supplemented with inorganic selenium(inSeMP)containing selenium(selenite)content of 0.3 mg/kg feed;(4)basal diet+mushroom powder enriched with organic selenium(orgSeMP)containing selenium(selenocysteine)content of 0.3 mg/kg feed.Mushroom powders were included at 6.5 g/kg of feed.Results In Period 1,there was no effect of diets on average daily gain(ADG)and gain:feed(G:F)ratio(P>0.05).The orgSeMP supplemented pigs had a lower average daily feed intake(ADFI)compared to all other groups(P<0.05).The ZnO supplemented pigs had reduced FS compared to the basal and mushroom group,while the orgSeMP supplemented pigs had lower FS compared to the basal group during the 21 d experimental period(P<0.05).In Period 2,there was no effect of diets on ADFI,ADG and G:F ratio(P>0.05).The orgSeMP supplementation increased the caecal abundance of bacterial members of the Firmicutes and Bacteroidetes phylum,including Lactobacillus,Agathobacter,Roseburia,and Prevotella and decreased the abundance of Sporobacter compared to the basal group,while inSeMP increased the caecal abundance of Prevotella and decreased the caecal abundance of Sporobacter compared to the basal group(P<0.05).Dietary supplementation with inSeMP increased expression of TLR4 and anti-inflammatory cytokine gene IL10 and decreased nutrient transporter gene FABP2 compared to the orgSeMP group(P<0.05).Conclusion OrgSeMP is a novel and sustainable way to incorporate selenium andβ-glucans into the diet of weaned pigs whilst improving FS and modulating the caecal microbiota.Alison Dowley Torres Sweeney Eadaoin Conway Stafford Vigors Marion T.Ryan Supriya Yadav Jude Wilson John V.O’Doherty 2023Journal of Animal Science and Biotechnology2023,14,3:1
