摘要:

采用灌喂试验研究AA肉鸡对海藻糖的吸收机理,以及日粮添加海藻糖对AA肉鸡生长及屠宰性能的影响,结果表明,海藻糖是以完整二糖形式直接吸收进入血液,而其他二糖一般分解为葡萄糖后吸收,此为海藻糖消化吸收原理方面的新发现。日粮添加海藻糖能显著促进肉鸡的生长,降低死淘率,显著提高半净膛率和全净膛率,提高屠宰性能。以0.1%添加量效果最优,可显著提高肉鸡体重9.42%(P<0.05),料肉比显著低于对照组(P<0.05)。

Abstract:

Crop feeding trial was conducted to study the absorption mechanism and the effects of trehalose on the growth performance and carcass characteristics of AA broilers. The results indicated that treherose was absorbed directly into the blood of AA broilers. That was different from other bisaccharides which was converted to glucose first and absorbed afterwards. This is a new discovery about the absorption mechanism of trehalose. Feeding with a basal diet supplemented with trehalose could significantly improve broiler growth, decrease mortality, and increase the carcass weight and eviscerated weight, and therefore improve the carcass characteristics of AA chicken. Adding 0.1% trehalose could have the best effect, with body weight gain increased notably by 9.42% (P<0.05) and feed/gain ratio decreased significantly (P<0.05) compared to the control group.
