Reproductive Traits Evaluation of Lime Buffalo (Bubalus bubalis) in Western Hills of Nepal

Abstract

The data pertaining to variable reproduction traits of Lime buffaloes were collected from Baglung and Gulmi during January, 2017 and March, 2018 for evaluation. Total 182 buffalo samples from Baglung and Gulmi were selected and data were collected using semistructured questionnaire and farmers record. Data entry and data analysis was done by using MS-Excel and R-statistical package, respectively. The least square mean comparison was done using Duncan’s multiple range test. The overall least-square means of age at first service, age at first calving, calving interval (CI), gestation length, postpartum estrus (PPE), and number of service were obtained as 1164.62±34.25 days, 1494.34±33.41 days, 448.47±21.02 days, 316.35±1.70 days, 107.47±17.14 days and 1.51±0.12, respectively. Location and parity had significant effect on PPE (p<0.01) and CI (p<0.01). The first postpartum heat in buffaloes varies greatly with parity and location. However, coat color had no significant effect on reproductive traits. The influence of nongenetic factors on the phenotypic expression of reproductive traits of buffaloes is important to determine the breeding competence in farm animals.
