| 1 | Metabolizable energy,nitrogen balance,and ileal digestibility of amino acids in quality protein maize for pigs显示文摘Background:To compare the nutritional value and digestibility of five quality protein maize(QPM) hybrids to that of white and yellow maize,two experiments were carried out in growing pigs.In experiment 1,the energy metabolizability and the nitrogen balance of growing pigs fed one of five QPM hybrid diets were compared against those of pigs fed white or yellow maize.In experiment 2,the apparent and standardized ileal digestibility(AID and SID,respectively) of proteins and amino acids from the five QPM hybrids were compared against those obtained from pigs fed white and yellow maize.In both experiments,the comparisons were conducted using contrasts.Results:The dry matter and nitrogen intakes were higher in the pigs fed the QPM hybrids(P < 0.05) than in the pigs fed white or yellow maize.Energy digestibility(P < 0.001) and metabolizability(P < 0.01) were higher in the pigs fed the white and yellow maize diets than in those fed the QPM diets.The AID of lysine was higher(P< 0.01) in the QPM diets than in the white and yellow maize.The AIDs of leucine,isoleucine,valine,phenylalanine,and methionine were lower in the QPM diets than those of maize(white and yellow)(all P < 0.05).Maize(white and yellow) had greater SIDs of leucine,isoleucine,valine,phenylalanine,glutamic acid,serine,alanine,tyrosine,and proline(P < 0.05).Conclusions:Based on these results,it was concluded that QPM had a lower metabolizable energy content and a higher amount of digestible lysine than normal maize. | Gerardo Mariscal-Landin Tercia Cesaria Reis de Souza Ericka Ramirez Rodriguez | 2014 | Journal of Animal Science and Biotechnology2014，5，4： | 0 |
| 2 | Effects of corn gluten feed inclusion at graded levels in a corn-soybean diet on the ileal and fecal digestibility of growing pigs显示文摘Background:This study aimed to determine the effect of the inclusion of com gluten feed(CGF) on the apparent and standardized ileal digestibility of protein and amino acids and the apparent ileal and total tract digestibility of energy in growing pigs.The study was performed using 16 barrows(weight,45.3 ± 4.5 kg) that were fitted with a T cannula at the terminal ileum.There were four treatments:a corn-soybean diet without CGF and three corn-soybean diets containing increasing levels of CGF(65,130,and 195 g/kg).Data were analyzed according to a randomized complete block design,four blocks with four pigs each(one pig per treatment).The trend of the response(linear or quadratic) was determined using orthogonal contrasts,and when a linear effect was determined,a linear equation was obtained.Results:The results showed that the inclusion up to 195 g/kg of CGF in the corn-soybean diet did not diminish the ileal digestibility(apparent and standardized) of protein and amino acids(P > 0.05),except that of phenylalanine,cystine,and proline.A linear decrease(P< 0.05) per gram of CGF added to the diet in the apparent and standardized ileal digestibility of phenylalanine(0.011 and 0.015 percentage units,respectively),cystine(0.048 and 0.043 percentage units,respectively),and proline(0.045 and 0.047 percentage units,respectively) was noted.Similarly,ileal digestibility of dry matter and energy were adversely affected(reduced by 0.028 and 0.025 percentage units,respectively,per gram of CGF increment in the diet).A significant(P< 0.05) linear reduction in total tract digestibility with increase in CGF amount in the diet was observed for energy(0.027 percentage units),dry matter(0.027 percentage units),crude protein(0.020 percentage units),and neutral detergent fiber(0.041 percentage units) per gram of CGF added to the diet.Conclusion:CGF did not affect the ileal digestibility of protein and most amino acids but reduced the ileal and total tract digestibility of energy. | Gerardo Mariscal Landin Tercia Cesaria Reis de Souza Ericka Ramirez Rodriguez | 2015 | Journal of Animal Science and Biotechnology2015，6，1： | 0 |
