Maturing pattern for body size, doe reproductive performance and kid mortality rate of savanna and red kalahari goats

The domestic production level of chevon only able to meet 13% of the demand. Savanna and Red Kalahari goats were brought from South Africa to evaluate their potential under Malaysian environment thus, can fulfill the local demand of chevon meat. Growth and reproduction are among the aspects being looked at to determine the economic merits. The objective of this study was to evaluate the performance of Savanna and Red Kalahari goats in terms of mature size, reproductive performance and kid mortality rates under Malaysian conditions. Brody, Gompertz, von Bertalanffy, and Logistics models were used to determine the mature size (A) and maturation rate (k) of Savanna and Red Kalahari does. The goodness of fit of the models was determined by the highest coefficient of determination (R2).The estimated mature weight of Savanna goats as derived from Brody, Gompertz, von Bertalanffy, and Logistic model was 52.57 kg, 52.06 kg, 52.18 kg, and 51.89 kg while for Red Kalahari goats was 52.96 kg, 48.88 kg, 49.81 kg, and 47.24 kg respectively. All the parameters taken fit in the model excellently (R2 above 90%). The best fit model for estimated mature weight of Savanna and Red Kalahari goat were von Bertalanffy Model (94.7%) and Brody Model (97.7%). An estimated asymptote for body length and height at withers derived from Brody, Gompertz, von Bertalanffy, and Logistic models showed that Red Kalahari were longer (P<0.05) and taller (P
