Therapeutic management, genital changes versus blood biochemical constituents of repeat breeder crossbred cows

The study was aimed to determine the genital changes, blood biochemical profile and efficacy of different treatment protocols in addressing repeat breeding in crossbred cattle with prolonged oestrus which was usually associated with ovulatory defects such as anovulation and delayed ovulation. For this a total of 48 repeat breeder cows with the history of prolonged oestrus and with apparently normal oestrual discharge were selected and divided into 4 groups and each comprising 12 animals. Various commonly used therapeutic techniques like administration of hCG drug with or without supportive treatment, multiple A.I. and supportive treatment alone was used in the present study. Efficacy of treatment was based on post treatment conception rate and found that the hormone hCG was the choice of drug for treatment of repeat breeding without uterine infection resulting in post treatment conception rate of 83.33 per cent which increased to 91.66 per cent when fortified with supportive treatment. In terms of genital changes occurring in repeat breeder cows under different treatment regimens in the present study it could be mentioned that there was no much variation between treatment regimens
