| 摘 要： | 分4批从孵出的海波罗鸡雏中选出888只公母混合雏，每批222只，研究几内亚热带气候对海波罗肉仔鸡生长期耗料量的影响。结果表明，4批鸡的整个试验中的累计耗料量分别为4745.58g/只、4507.44g/只、4682.73g/只和4545.77g/只。第Ⅱ、Ⅲ和Ⅳ批鸡的累计耗料量比第Ⅰ批鸡分别少5.28%、1.13%和4.40%，第Ⅱ和第Ⅳ批累计耗料量比第Ⅲ批分别少4.11%和3.23%，第Ⅱ批累计耗料量比第Ⅳ批的少0.5%，比第Ⅰ、Ⅲ和Ⅳ批偏少。4批鸡4周龄料肉比分别为1.23、2.03、1.90和1.67，饲料报酬都高，7周龄分别为3.78、2.97、2.56和2.52，除第Ⅰ批外，各批7周龄饲料报酬较高。在整个试验期，4批鸡1－7周龄的平均累计耗料量为4622.88g/只，其平均累计料肉比为2.28g，累计耗料量比海波罗的标准少217.12g，即4.70%。由于几内亚热带气候影响，本试验鸡采食量少，料肉比较低。

| Abstract: | This experiment investigates the influence of Guinea climatic tropical conditions on the rate of feed consumption and feed/meat ratio of hybro broiler chicken, with the aim of coming up with internal feeding management hand book in the future. 888 newly hatched broilers of both sex were selected and group into four batches, 222broilers per batch. The results were as follows: the accumulative total feed intake of the four batches during the whole process were 4 745.58g per broiler, 4 507.44g per broiler, 4 692.73g per broiler and 4 545.77g per broiler, respectively; the total feed intake of the second, third and forth batch were 5.28%,1.13% and 4.40% less than that of the first batch, respectively; those of the second and forth batch were 4.11% and 3.23% less than that of the third batch respectively; the feed intake of the second batch was 0.85 less than that of the forth batch,and were less than those of the first, third and forth batch; the feed/meat ratios at the forth week of the four batches were 1.23,2.03,1.90 and 1.67, respectively and the feed efficiency was high; at the seventh week, they were 3.78,2.97,2.56 and 2.52, respectively, the feed efficiency were higher except the first batch; the rate of total feed consumption of the four groups of chicken were 4622.88g/individual, and the feed/meat ratios of the four groups were 2.28. The average of the total feed intake of the four groups compared with the original source (hybro broilers in Holland) the standard is 4.7% less than 217.12g. This experiment indicates that the influence of Guinea climatic tropical conditions causes reduction in both a feed consumption rate and feed/ meat ratio. |
