EFFECT OF SITE OF SEMEN DEPOSITION ON CONCEPTION RATE IN ONGOLE COWS

Abstract

A trial was conducted on 234 Ongole Cows having 40 to 120 days postpartum interval to know the effect of site of semen deposition on conception rate. Animals were divided into three groups based on site of semen deposition. All the inseminations were done 10-12 hours following the detection of standing estrus with frozen semen (0.5 ml straw). 64 Cows were inseminated mid cervically (Group I), 83 Cows were inseminated into the body of uterus (Group II) and 87 cows were inseminated deep into the uterine horn (Group III) ipsilateral to the impending ovulation. A Higher conception rate (73.63%) was observed with deep intra-uterine horn insemination than the body of uterus (63.79%} and mid-cervical (53.68%) inseminations.
