Evaluation of thermal energy consumption in broiler farms and saving strategies

ABSTRACT The aim of this study was to evaluate thermal energy consumption in broiler farms and provide solutions to reduce it. This study was performed with a completely randomized design under 4 climatic conditions, including Ardabil (cold climate representative), Khuzestan (warm climate representative), Isfahan (dry climate representative) and Guilan (temperate climate representative) in 4 replicates (4 broiler farms in each climate) and with 5 repetitions (5 periods of breeding per unit) and a capacity of 492,700, Ross 308 broiler in each breeding period. According to the results, in all climates, the proposed solutions to save thermal energy were able to create a significant difference (P<0.05). The experimental results also showed that the difference in thermal energy consumption in cold and dry climates wasmuch higher than in temperate and warm climates (P<0.05). Overall, the results of the present study show that, by optimizing andmodernizing construction equipment in broiler farms, thermal energy losses can be reduced in all climatic conditions.

摘要
本研究旨在评估肉鸡养殖场的热能消耗情况，并提出相应的节能降耗方案。本研究采用完全随机设计，设置4种典型气候场景，分别为阿尔达比勒（代表寒冷气候）、胡齐斯坦（代表炎热气候）、伊斯法罕（代表干旱气候）及吉兰（代表温带气候）；实验设置4个重复组（每个气候条件下配置4个肉鸡养殖场），并开展5次重复养殖（每个单元完成5个养殖周期），每个养殖周期的饲养规模为492700羽Ross 308肉鸡。
研究结果显示，在所有气候条件下，所提出的热能节约方案均能产生显著差异（P<0.05）。实验结果还表明，寒冷与干旱气候下的热能消耗差异显著高于温带与炎热气候（P<0.05）。综上，本研究结果证实，通过优化并升级肉鸡养殖场的建筑设施，可在各类气候条件下降低热能损耗。
