摘要

为了评估饲喂卷边饼对消化酶的影响，将杂交小母牛（n=32；494±10kg体重）饲喂含有20%（干物质基础）干玉米酒糟加可溶性或卷边饼的日粮111天。相对于体重，饲喂卷边饼的小母牛的胰腺质量更大（P=0.05）。胰腺（α-淀粉酶、胰蛋白酶和脂肪酶）和空肠（麦芽糖酶、葡糖淀粉酶和异麦芽糖酶）的消化酶活性在不同处理之间没有差异（P≥0.19）。我们的研究结果表明，喂食卷边蛋糕不会影响消化酶的活性。

The effects of feeding hempseed cake on pancreatic and jejunal digestive enzymatic activity in finishing heifers

To evaluate the effects of feeding hempseed cake on digestive enzymes, crossbred heifers ( n = 32; 494 ± 10 kg body weight) were fed diets containing 20% (dry matter basis) dried corn distillers grains plus solubles or hempseed cake for 111 days. There was greater ( P = 0.05) pancreatic mass relative to body weight in heifers fed hempseed cake. No differences ( P ≥ 0.19) in digestive enzyme activity in the pancreas (α-amylase, trypsin, and lipase) and jejunum (maltase, glucoamylase, and isomaltase) were observed between treatments. Our results suggest that feeding hempseed cake did not influence digestive enzyme activity.

期刊介绍： Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
