| 摘 要： | 将540只4周龄祖代固始鸡放养于一山地果园饲养至18周龄,利用其体重与体型参数的实测数据,讨论分析了放养条件下固始鸡的生长发育情况。结果表明:放养条件下祖代固始鸡4~10周龄以胫长、体斜长和胸骨长发育为主,10~18周龄以胸宽、胸深和骨盆发育为主;放养期体重增长缓慢;与舍饲条件相比,体重和骨骼生长均存在减缓和延迟现象。并给出了部分体型参数对日龄的拟合回归方程。

| Abstract: | 540 4-weeks-old ancestral Gushi chickens were reared freely in the mountain.The results of chickens the live boby weight and phenotypic traits showed that shank length,body length,and breastbone were fast during 4~10 weeks,chest width,chest depth and pelvis width are mainly growed at 10-18 weeks.The best change curves of phenotypic traits of Gushi chickens is established and standard to estimate the live boby weight and shank length growth for Gushi chickens were constructed. |
