Suresh Kumar, Ramesh Chandra and Kedare Gopal Madhav
The present investigation was conducted using 220 kidding records of Alpine Beetal goats to evaluate the influence of various factors on abnormal kidding, multiple birth, litter size and sex ratio. In this study, the abnormal kidding was 3.18%, twins 43.67%, triplets 8.18%, litter size 1.58 and sex ratio was 48.58% among normal kids. The rate of abnormal kidding was higher among single births than multiple births. Year of kidding had the significant (P<0.05) effect on abnormal kidding, twins, triplets and sex ratio. Season of kidding had the significant (P<0.05) effect on twins, triplets and sex ratio. However, kidding order had the significant (P<0.05) effect on sex ratio. Twinning percentage was significantly (P<0.01) higher (46.51%) in winter than in least kidding season (36.00%).
