Abstract

1. This study investigated the effects of different housing systems on oxidative defence mechanisms, heterophil functions, cellular immune response and cytokine production in laying hens. One hundred and twenty laying hens were allocated into one of four groups: conventional cages, furnished cages, deep litter, and free range.2. Housing system did not affect malondialdehyde concentrations and enzymatic antioxidant status. Ascorbic acid values were higher in deep-litter hens than in those in conventional cages and free range.3. Phagocytic and chemotactic activities tended to rise in the deep-litter system, and oxidative burst was higher than in furnished cages. Cytotoxic T cells were decreased in furnished cages, both cytotoxic and helper T cells decreased in deep litter compared to free range.4. The IL-2 and IL-13 expression was higher in deep litter than in conventional cages, and IL-6 expression was higher in furnished cages than in free range.5. Housing system had no significant effects on the oxidative defence system; however, they affected heterophil functions, cellular defence mechanisms and cytokine production. The results suggested that breeders need to consider the housing system's potential effects on immune defence responses while applying a breeding strategy appropriate for animal welfare and consumer demand.

不同饲养方式对蛋鸡氧化防御系统、异性嗜血杆菌功能、细胞免疫反应和细胞因子的影响

1.本研究调查了不同饲养方式对蛋鸡氧化防御机制、异性嗜血杆菌功能、细胞免疫反应和细胞因子产生的影响。将 120 只蛋鸡分为四组：传统笼养组、装修笼养组、深窝饲养组和自由放养组。饲养系统对丙二醛浓度和酶抗氧化状态没有影响。深层饲养的母鸡抗坏血酸值高于传统笼养和自由放养的母鸡。 3. 在深层饲养系统中，吞噬细胞和趋化活动呈上升趋势，氧化猝灭也高于有家具笼养的母鸡。5.饲养系统对氧化防御系统没有显著影响，但会影响异性嗜血杆菌的功能、细胞防御机制和细胞因子的产生。结果表明，饲养者在采用适合动物福利和消费者需求的饲养策略时，需要考虑饲养系统对免疫防御反应的潜在影响。

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 .
