Study of reproductive parameters of inseminated and stations reared female cattle in Togo

Abstract

The poor reproductive abilities of most tropical cattle are an obstacle to improving cattle production through artificial insemination (AI). The aim of this study was to determine the reproductive parameters of 23 cows and heifers reared on stations in Togo after an AI campaign. These females were inseminated following a hormonal heat synchronization protocol using Prid® Delta. Pregnancy and calving were monitored to assess reproductive parameters. Results showed a calving rate of 52.27% and a fertility rate of 47.73%. These rates varied significantly (p<0.05) according to parity, breed and body condition score. In addition, mean gestation period, mean age at first calving, calving interval -1st heats and calving interval - AI were respectively 9.38 ± 0.29 months, 3.57 ± 1.19 years, 45.90 ± 13.36 days and 5.04 ± 0.45 months. Comparative analysis of these parameters showed significant variations (p<0.05) in relation to female breed and parity. Reproduction parameters are of considerable importance in the valorization of local cattle through artificial insemination.
