摘要

1. 研究了不同包埋水平对肉鸡棉籽粕酶解生物活性肽的影响。试验饲粮中分别添加0、2.5、5、10、15和20 g/kg 6个水平的棉籽生物活性肽(CBP)。将432只1日龄肉鸡(Ross 308)随机分配到6个处理中,在完全随机设计的基础上重复6次。结果表明,饲粮中添加CBP可线性提高增重、采食量和饲料效率。由于采食量的增加,胴体产出率与CBP呈线性(p p p = 0.001)和二次(p = 0.021)关系,但肝脏相对重量随CBP含量的增加呈线性(p = 0.001)下降。综上所述,在肉鸡饲粮中添加CBP具有改善生产性能、改善回肠蛋白质和氨基酸消化率的潜力,可作为一种新型功能蛋白质应用于家禽饲粮中。

Effects of cottonseed meal bioactive peptides on growth performance, ileal digestibility, serum amino acid and immune responses of broiler chickens.

1. The influence of different inclusion levels of a bioactive peptide derived from cottonseed meal by enzymatic hydrolysis was examined in broilers. Experimental diets contained six inclusion levels of cottonseed bioactive peptides (CBP) at 0, 2.5, 5, 10, 15 and 20 g/kg of diet. A total number of 432, one-day-old broiler chicks (Ross 308) were randomly allocated to one of six treatments, which were replicated six times based on a completely randomised design.2. The results showed that CBP in the diet linearly increased body weight gain feed consumption and so FCR. As a result of the higher feed intake, CBP linearly (p < 0.05) increased FCR. However, when corrected for the body weight differences (d 35), there was no significant effect of CBP on FCR.3. The CBP inclusion improved crude protein and Arg, His and Met ileal digestibility in a linear manner (p < 0.01). Serum concentration of Lys, Trp, Ala and Orn decreased linearly (p < 0.05) as the concentration of CBP increased in the diet.4. Antibody titres against Newcastle disease, sheep red blood cell (SRBC) and serum concentration of IgY, IgM, IgA and GSH, red blood cell count and haematocrit increased in line with CBP inclusion.5. There was both a linear (p = 0.001) and quadratic (p = 0.021) response for carcase yield percentage, although the liver's relative weight linearly (p = 0.001) decreased with higher CBP inclusion.6. Overall, the data showed that dietary supplementation of CBP in broiler diets has the potential to improve performance traits, ileal protein and amino acid digestibility and can be used as a novel functional protein in poultry diets.

期刊介绍: From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
