Abstract

The present study was conducted to study the clinical efficacy of clomiphene citrate and Ovsynch protocol treatment on fertility in buffalo heifers during summer season. Total eighteen buffalo heifers were given initial treatment and after ten days of initial treatment, the selected buffalo heifers were divided into three groups. In Group-I (n=6) two tablets of 1% copper sulphate solution was administered to each buffalo heifer and after 30 minutes 300 mg tablet of clomiphene citrate was administered orally for five consecutive days. In Group-II(n=6) buffalo heifers were treated with Ovsynch synchronization protocol while Group-III (n=6) was untreated control group. The percentage of estrus exhibition was 50, 100 and 0 per cent in Group-I, Group-II and Group-III, respectively. The average time required for onset of estrus in buffalo heifers was 136 ± 8 hrs in Group-I while 67.83 ± 4.12 hrs in Group-II. The result is statistically significant at (P
