摘要
本试验旨在研究Maxigrain®(M)酶对家兔生理机能、生产性能和营养物质消化率的影响。试验选用5 ~ 6周龄的杂交断奶兔20只,随机分为5个饲粮处理,分别为0 g M,即大豆不含M(对照)和GLM中添加M(50、100、150和200 g M / kg GLM)。采用完全随机设计,每个处理4只兔,重复1只兔。各生理指标和生产性能指标以及粗脂肪、纤维和NFE消化率均无显著(p > 0.05)影响。干物质消化率、粗蛋白质消化率和灰分消化率各处理差异显著(p < 0.05)。这表明直接从兔盲肠中喂食软粪便(称为粪食机制)具有其附带的营养益处。这一优势可以使兔在添加或不添加酶的情况下有效和高效地利用饲料或饲料基饲料。

The objective of this experiment was to determine the effects of feeding rabbits with Maxigrain® (M) enzyme supplemented Gliricidia sepium leaf meal (GLM) on their physiology, performance characteristics, and nutrients digestibility. Twenty weaned rabbits of mixed sexes, 5-6 weeks old, were randomly allotted to five dietary treatments including 0 g M which was soybean without M (control) and GLM supplemented with M at 50, 100, 150 and 200 g M per kilogramme of GLM. There were four rabbits per treatment and one rabbit as replicate in a completely randomized design. There were no significant (p > 0.05) treatment effects in all physiological and performance indices as well as those of crude fat, fibre and NFE digestibilities. There were variations (p < 0.05) due to the treatment effects on dry matter, crude protein and ash digestiblities. This implies that the feeding of soft faeces directly from the caecum called coprophagy mechanism in rabbits has its concomitant nutritional benefits. This advantageous benefit can enable rabbit to effectively and efficiently utilize forage or forage-based diet with or without enzyme supplementation.
