Abstract:
The present investigation was undertaken to evaluate the effect of genetic and non-genetic factors on reproductive traits in Deccani flock comprising records of 53 animals maintained at Livestock Research Station, Mahabubnagar, Telangana State from October, 2012 to July, 2015. The least-squares means recorded were 338.59 ± 9.36 days, 21.89 ± 0.50 kg, 644.65 ± 11.59 days, 24.56 ± 0.33 kg, 155.53 ± 0.49 days, 1.00 ± 0.00 and 0.80 ± 0.04 for age at first tupping, weight at first tupping, age at first lambing, weight at first lambing, gestation period, litter size at birth and litter size at weaning respectively. All the reproductive traits studied in the present investigation revealed that the reproductive traits studied were significantly influenced by season of birth of ewe (P<0.01).
