 ABSTRACT

Gestation length, the period from effective fertilization until calving, is a reproductive trait that significantly affects buffalo’s breeding and production. The objective of this study was to determine the effect of genetic and environmental factors affecting gestation length. Data included information from June 2010 to December, 2014 on 5214 graded Murrah buffalo. Heritability was estimated on sire of live born calves. The least square mean of gestation period of Graded Murrah buffaloes maintained under field conditions in India was 308.68 ± 0.16 days. Analysis of data suggested that Agro climatic zones, season of breeding, body score condition of buffaloes and order of lactation accounted for significant variation (P<0.01) in the length of gestation period, of sex of calf was not significant (P>0.01). The low heritability estimate (0·07±0·003) calculated from the sire of live born calf, suggestive of the non-genetic sources contributed a major share to variation. More accurate prediction of calving dates can help dairy producers to meet management requirements of pregnant animals and to administer better health care during high-risk phases of animals’ lives.

Key words: Gestation length, Heritability, Graded Murrah buffalo, Least square mean.
