Abstract

This study investigated the effects of partially replacing soybean meal (SBM) with high-fibre cottonseed meal (HF-CSM) on performance traits and expression of certain nutrient co-transporter genes in the small intestine of male broiler chickens. The HF-CSM had lower CP and AME but higher EE, CF, NDF, and ADF compared to SBM. The free gossypol (FG) concentrations in the HF-CSM-containing diets were well below the limit (100 mg/kg) permitted by the European Union in complete chicken feed. Replacing up to 15 % of SBM in the diets of the experimental chickens with the HF-CSM had an insignificant (P > 0.05) effect on BW, FCR, or European Productivity Index at the time of harvest (42 d), and the 10 % replacement of SBM with HF-CSM (equivalent to 2.5 % inclusion of HF-CSM in the total ration) had effects similar to the all-SBM diet. Viscosity of jejunal digesta increased with the inclusion level of HF-CSM in diet when measured at 24 d (P = 0.048, linear effect) and 48 d (P = 0.001, quadratic effect). Inclusion of the HF-CSM upregulated the expression of nutrient co-transporter genes responsible for absorption of small peptides (PEPT-1), glucose and other hexose sugars (SGLT-1, GLUT-5), and amino acids (EAAT-3) in the small intestine at 24 d (P = 0.001, linear effect) and 42 d (P = 0.001, quadratic effect). Expression of PYY mRNA, associated with satiety regulation, increased with HF-CSM levels in diet at 24 d (P = 0.0001 linear effect) and 42 d (P = 0.001, linear effect), suggesting a potential anorexigenic effect. The study suggests that inclusion of HF-CSM by replacing 10-15 % of SBM on a weight-to-weight basis, which translates into 2.5–3 % inclusion of the former in the whole ration, may sustain the performance of broiler chickens
饲粮中用棉籽粕部分替代豆粕可通过上调小肠营养转运蛋白基因的表达来维持肉鸡生产性能
本试验旨在研究高纤维棉籽粕(HF-CSM)部分替代豆粕(SBM)对肉鸡生产性能及小肠部分营养共转运蛋白基因表达的影响。与SBM相比,HF-CSM的CP和AME较低,但EE、CF、NDF和ADF较高。含hf - csm的日粮中游离棉酚(FG)浓度远低于欧盟允许的全鸡饲料中游离棉酚(FG)的限值(100 mg/kg)。用HF-CSM替代试验鸡饲粮中高达15%的SBM,对试验鸡的影响不显著(P >;0.05)对收获时(42 d)的体重、体重比或欧洲生产力指数的影响,而用糠粕替代10%的糠粕(相当于在总日粮中添加2.5%的糠粕)的效果与全糠粕相似。24 d和48 d空肠食糜粘度随饲粮中HF-CSM添加水平的增加而增加(P = 0.048,线性效应)。HF-CSM的加入上调了24 d (P = 0.001,线性效应)和42 d (P = 0.001,二次效应)小肠中负责吸收小肽(PEPT-1)、葡萄糖和其他已糖(SGLT-1、GLUT-5)和氨基酸(EAAT-3)的营养共转运基因的表达。PYY mRNA的表达与饱腹感调节有关,随着饲料中HF-CSM水平在24 d (P = 0.0001线性效应)和42 d (P = 0.001线性效应)的增加而增加,表明可能存在厌食作用。本研究表明,在肉鸡日粮中添加HF-CSM以替代10- 15%的SBM,即在整个日粮中添加2.5 - 3%的SBM,可以维持肉鸡的生产性能

期刊介绍: The Journal of Applied Poultry Research (JAPR) publishes original research reports, field reports, and reviews on breeding, hatching, health and disease, layer management, meat bird processing and products, meat bird management, microbiology, food safety, nutrition, environment, sanitation, welfare, and economics. As of January 2020, JAPR will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. The readers of JAPR are in education, extension, industry, and government, including research, teaching, administration, veterinary medicine, management, production, quality assurance, product development, and technical services. Nutritionists, breeder flock supervisors, production managers, microbiologists, laboratory personnel, food safety and sanitation managers, poultry processing managers, feed manufacturers, and egg producers use JAPR to keep up with current applied poultry research.
