Reproductive performance of different goat breeds in Malaysia

The study was conducted to investigate the effect of a controlled internal drug release (CIDR) device in three goat breeds of Malaysia using Artificial Insemination (AI), on the reproductive performance, which included; Estrus Synchronization (ES), pregnancy, singleton, twin, and mortality rate. Sixty goats were divided in to treatment group (TRE: n = 30) which received CIDR for 9 days and AI was done on 10th day, and a control group (CON: N = 30). Three goat breed, namely, Kambing Katjang (KK), Boer and Jamnapari, (n = 20 to each strain), were used in this study. . . Data were analyzed to determine the effects of CIDR and strain on the reproductive performance of goats. ANOVA or T-test were used to analyze data for the effects of CIDR and breed. Finding showed the using of CIDR and breed may effect of reproductive performance. Results indicated that the CIDR can be used to activate the reproductive system, accelerate estrus cycle, and increase twin rates. Boer strain that might help to improve herd production by producing twins.
