Abstract

1. This study compared two broiler housing models with different technologies (conventional versus fully automated climate control) to verify their performance and carcass characteristics at slaughter, as well as the economics of production.2. A database regarding 20 443 flocks of heavy broilers produced in an integrated operation during the years 2020 and 2021, in eight Brazilian regions was used in the analysis. The dependent variables included feed conversion, average live weight gain, total and partial carcass condemnation and the total mortality. For economic analysis, the production cost of each technology including feed, labour, energy, heating and depreciation was calculated.3. The technology used in the broiler houses had a significant effect on the technical indicators which were positive for fully automated climate control in most geographical regions. One important exception was the effect on total and partial carcass condemnations, with better results seen for conventional housing. The total cost per ton of broiler meat delivered, deducting condemnation losses, was lower in the automated climate controlled housing compared to conventional housing.4. In conclusion, there was a reduction in broiler chicken production costs for birds raised in fully automated climate controlled housing, indicating better economic results for this model in Brazil.

全自动气候控制肉鸡房舍在技术和经济性能上都更胜一筹。

1.本研究比较了两种采用不同技术（传统气候控制与全自动气候控制）的肉鸡饲养模式，以验证它们的性能、屠宰时的胴体特征以及生产的经济性。 2. 分析中使用了一个数据库，该数据库涉及 20 443 群在 2020 年和 2021 年期间在巴西 8 个地区以综合方式生产的重型肉鸡。因变量包括饲料转化率、平均活增重、胴体总腐烂率和部分腐烂率以及总死亡率。在经济分析中，计算了每种技术的生产成本，包括饲料、劳动力、能源、加热和折旧。 3.肉鸡舍采用的技术对技术指标有显著影响，在大多数地区，全自动气候控制技术对技术指标有积极影响。一个重要的例外是对胴体总报废率和部分报废率的影响，传统鸡舍的效果更好。总之，全自动气候控制鸡舍饲养的肉鸡生产成本有所降低，表明这种模式在巴西具有更好的经济效益。

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 .
