Abstract

A chick growth assay was conducted to investigate the effect of dietary L-homoarginine supplementation on performance of chicks fed a Lys-deficient corn-feather meal diet. Weight gain, feed intake, and feed efficiency increased linearly (P < .01) as Lys was added at .1 and .2% from feed-grade L-Lys.HCl. Adding homoarginine at .2% resulted in less (P < .05) weight gain and feed intake than observed in chicks fed the unsupplemented basal diet. These data suggest that dietary homoarginine had no Lys bioactivity, but may also have antagonized Lys utilization from the basal diet.

摘要

进行了一项雏鸡生长试验，以研究在低赖氨酸玉米-羽毛粉日粮中添加L-高精氨酸对雏鸡生产性能的影响。随着饲料级L-赖氨酸盐酸盐以0.1%和0.2%的比例添加赖氨酸，体重增加、采食量和饲料效率呈线性增加（P < 0.01）。添加0.2%的高精氨酸导致体重增加和采食量低于（P < 0.05）未添加基础日粮的雏鸡。这些数据表明，日粮中的高精氨酸没有赖氨酸生物活性，但也可能拮抗基础日粮中赖氨酸的利用。
