 ABSTRACT

This study was conducted to analyze the impact of conception in estrus synchronized bovines. Therefore hundred estrus synchronized and fifty non-estrus synchronized bovines were selected at random sampling method and considered for the study. The logistic regression analysis employed to estimate the probability of a particular beneficiary bovines not being able to conceive due to estrus synchronization. The result of logistic regression revealed that relationship of conception rate with discharge, average milk yield and estrus detection before synchronization were significant. Insignificant variables such as breed, postpartum interval, age at first calving, average calving interval, lactation length and abortion were indicated partial contribution to the model. Normally discharging bovines showed high conception rate where as average milk yield and estrus detection before synchronization decreased the conception rate.

Key words: Bovine, Oestrus syncronization, Conception Rate, Binary logistic regression analysis.
