The aim of this paper was to evaluate the effects of toasted soybean grains on bioeconomic performance of pullets and layer hens in hot and humid environment. A total of 972 three-week-old Harco chicks were divided into 12 groups. At starter, pullet and laying phases, birds were fed four diets containing 0% (R0), 5% (R5), 10% (R10), and 15% (R15) of soybean grains. Results showed similar feed intake, body weight gain, laying rate, feed conversion ratio, and mortality rate between dietary treatments at each phase. The egg weight increased significantly in diet R15 (P < 0.05). The use of soybean grains reduced the feed prices. Feeding cost decreased significantly (P < 0.05) during growth and laying phases in soybean grains added diets. Feeds efficiency increased significantly (P < 0.05) with the increase of dietary soybean grains rate. Properly toasted soybean grains can be therefore included up to 15% in heavy line layer hens' diet in tropical conditions.
本文旨在评估烘焙大豆对炎热潮湿环境中雏鸡和蛋鸡生物经济性能的影响。总共972只三周龄的哈科雏鸡被分成12组。在雏鸡、育成鸡和产蛋阶段，给鸡饲喂四种分别含有0%（R0）、5%（R5）、10%（R10）和15%（R15）大豆的日粮。结果表明，各阶段不同日粮处理之间的采食量、体重增加、产蛋率、饲料转化率和死亡率相似。R15日粮组的蛋重显著增加（P < 0.05）。大豆的使用降低了饲料价格。添加大豆的日粮在生长和产蛋阶段的饲养成本显著降低（P < 0.05）。随着日粮中大豆比例的增加，饲料效率显著提高（P < 0.05）。因此，在热带条件下，重体型蛋鸡日粮中可适当添加高达15%的烘焙大豆。
