Reproductive performance of Matou goat under sub-tropical monsoonal climate of Central China.
The aim of the current study was to estimate reproductive parameters of Matou goat to evaluate a meat breed. Data on 2,560 kids from 1,197 kidding records of 638 does and on puberty of 546 females kids were collected from farmer household herds of Matou goats in six counties of Shiye city under Hubei Province in China. Statistical analyses on puberty, estrus, gestation length (GL), litter size (LS) and survival rate (SR) of kids at puberty were performed with software Genstat 5 (Release 3.1) by using descriptive statistics and regression models. The results showed that age at puberty of female kids was 108.4+/-19.1 days while estrus duration and cycle averaged 58.6+/-15.9 hours and 19.7+/-1.5 days respectively. Gestation length (GL) and litter size (LS) averaged 150+/-7.4 days and 2.14+/-0.9 respectively with 90.8% of survival rate (SR) of kids. GL was unassociated with parity, but delayed as LS increased. SR of kids at birth differed remarkably among parity 1 to 5, decreased significantly at parity 6 to 7, and then increased at 8th parity. In Matou goat over all twinning and triplet percentage was 45.4 percent and 16.3 percent whereas percentage of single birth was 27.4 percent. As twins and triplets birth rate is considerably higher in Matou goat so, this breed can be recommended to other parts of China and the world having similar climatic conditions.
