摘  要：
为研究不同饲养方式对福清山羊生长曲线的影响,分别测定了全圈养组(A组)、圈养+放牧组(B组)、放牧组(C组)条件下断奶福清山羊羯羊3月龄到12月龄的体重,并采用Von Bertalanffy、Gompertz和Logistic 3种非线性生长模型拟合其体重生长曲线.结果表明:12月龄B组山羊体重显著高于C组(P<0.05),A组体重高于C组,二者差异不显著(P>0.05);随着日龄的增长各饲养方式的平均日增重和相对生长率均呈现下降趋势.Von Bertalanffy模型的拟合效果最优,预测A组、B组和C组的成熟体重分别为33.583、39.96和31.564kg,拐点月龄分别为3.24、4.19和2.95,拐点体重分别为9.95、11.84、9.35kg,B组拐点月龄明显长于A组和C组,前期快速生长时期长,表明圈养+放养是适合福清山羊育肥的饲养方式.

摘  要：
Body weights of 3 to 12 months old Fuqing goats raised under 3 different methods of husbandry were measured to analyze their growth patterns with Von Bertaanffy,Gompertz and Logisticmodels.At 12-month-old,the goats in Group B(fenced-in feeding and free-range grazing)weighed more than those in Group A(fenced-in feeding)followed by those in Group C(free-range grazing)with a significant difference between Group B and Group C.The average daily weight gain and the relative growth rate declined in all groups as the goats aged.The Von Bertalanffy model best fitted the growth patterns of the goats showing the mature body masses for Group A,B and C as 33.583,39.96 and 31.564 kg,respectively.The deflection points on the curve for the age of Group A,B and C goats were 3.24,4.19 and 2.95 month,respectively;while those for the body weight,9.95,11.84 and 9.35 kg,respectively.The results demonstrated the housing system,fenced-in feeding and free-range grazing,was suitable for the fatten product of Fuqing goats.
