Abstract

Abstract This study investigated the effects of dietary lupin (LP) as a replacement for soybean meal (SBM) on the performance, meat quality, and blood parameters of broilers. A total of 960 1-day-old Ross 708 broilers were divided into four dietary groups. The four diets were formulated with different levels of dehulled LP content in place of SBM; LP0: 0, LP50: 50, LP100: 100, and LP200: 200g/kg. There was a trend (P < 0.10) for reduced weight gain in the LP200 group compared with other groups. The feed conversion ratio was higher (P < 0.05) in the LP200 group than in the LP0 and LP50 groups. Concerning breast meat characteristics, the lightness color (L*) was lower (P < 0.05) in the LP200-fed group compared with the LP0 group. Polyunsaturated fatty acids were higher (P < 0.05) in LP100- and LP200-fed chickens than in LP0-fed chickens. Serum HDL cholesterol was significantly (P < 0.05) higher in the group fed LP200 compared with the groups fed LP0 and LP50. A higher serum concentration of interleukin (IL)-2 was found in groups fed LP100 and LP200 than in groups fed LP0 and LP50. Our results suggest that LP could be a dose-dependent SBM substitute, and that the optimal level of LP inclusion is approximately 100g/kg.

豆粕替代品卢平对肉鸡生产性能、肉品质和血液指标的影响
摘要本试验旨在研究饲粮中添加罗苹(LP)替代豆粕(SBM)对肉鸡生产性能、肉品质和血液指标的影响。将960只1日龄罗斯708肉鸡分为4个饲粮组。在4种饲粮中分别添加不同水平的脱壳粗脂蛋白来代替豆粕;LP0: 0, LP50: 50, LP100: 100, LP200: 200g/kg。与其他各组相比,LP200组的增重有降低的趋势(P < 0.10)。LP200组的饲料系数高于LP0和LP50组(P < 0.05)。在胸肉性状方面,lp200饲喂组的亮色(L*)低于LP0饲喂组(P < 0.05)。饲喂LP100和lp200的鸡多不饱和脂肪酸含量高于饲喂lp0的鸡(P < 0.05)。LP200组血清高密度脂蛋白胆固醇显著(P < 0.05)高于LP0和LP50组。饲喂LP100和LP200组血清白细胞介素-2浓度高于饲喂LP0和LP50组。我们的研究结果表明,LP可能是一种剂量依赖性的SBM替代品,并且LP的最佳包含水平约为100g/kg。

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.
