Abstract

1. This study assessed the effects of in ovo injection of Marek's disease vaccine (MDV), alone (control) or combined with 1.25 μg of 25-hydroxycholecalciferol (25(OH)D3), on hatchability, chick quality, performance and bone quality in Cobb 500 broilers. At d 19 of embryo development, eggs were injected with 0.05 ml of MDV or MDV plus 1.25 μg of 25(OH)D3 into the amniotic fluid following hatchery protocol. Post-hatch, 840, one-day-old male chicks were reared until d 35 of age.2. Hatchability and general chick quality were not affected by the treatments. However, the male chicks that received MDV + 1.25 μg of 25(OH)D3 presented longer length at flock thinning compared to those that received only MDV. At 35 d of age, broiler performance, gait score and leg deformities (valgus and varus) were not affected.3. Although chicks receiving the MDV + 1.25 μg of 25(OH)D3 had lower macroscopic tibial dyschondroplasia (TD) scores at 7 d of age compared to those given MDV, this difference was not sustained as they matured. Tibia weight, thickness and length were similar across treatments at all time points. However, the tibiae from chicks in the MDV + 1.25 μg 25(OH)D3 group demonstrated greater strength on d 1 and 7 but not at later times.4. In conclusion, this study showed that combining 25(OH)D3 with MDV does not impact hatchability or overall performance but does enhance early bone strength and growth in broiler chicks.

蛋内注射25(OH)D3联合马立克病疫苗对肉鸡孵化率、生产性能和骨骼健康的影响
1. 本试验研究了在蛋内注射马立克病疫苗(MDV),单独(对照)或联合1.25 μg 25(OH)D3胆钙化醇(25(OH)D3)对Cobb 500肉鸡孵化率、雏鸡品质、生产性能和骨质量的影响。在胚胎发育第19 d时,按照孵化方案,在羊水中注射0.05 ml MDV或MDV加1.25 μg 25(OH)D3。孵化后,840只1天大的雄性雏鸡被饲养到35岁。不同处理对雏鸡的孵化率和总体质量没有影响。然而,注射MDV + 1.25 μg 25(OH)D3的雄性雏鸡比只注射MDV的雏鸡在减群时的体长更长。35日龄时,肉鸡生产性能、步态评分和腿部畸形(外翻和内翻)均未受影响。虽然注射MDV + 1.25 μg 25(OH)D3的雏鸡在7日龄时的肉眼胫骨软骨发育不良(TD)评分低于注射MDV的雏鸡,但随着雏鸡的成熟,这种差异不会持续下去。各治疗时间点胫骨重量、厚度和长度相似。然而,MDV + 1.25 μg 25(OH)D3组的鸡胫骨在第1天和第7天表现出更大的强度,但在以后的时间里则没有。综上所述,25(OH)D3与MDV的组合不影响肉鸡的孵化率和整体生产性能,但能提高肉鸡早期骨强度和生长。

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 .
