Abstract:
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.
