Abstract: A study was conducted to compare the efficacy of nutritional and hormonal supplements for treatment of true anoestrus in crossbred jersey cows based on estrus induction response and post treatment conception. The response rate to different treatment regimen in terms of manifestation of external signs of oestrus was recorded as 85.71, 57.14 and 100% in group A (supportive treatment with only minerals and vitamins), B (supplemented with hormones) and C (supplemented with both supportive and hormones) respectively. The overall conception rate was higher in group C (85.71%), group A (83.33%) and lower in group B with 50%. There was no significant difference in conception rate between groups A and C pertaining to conception rate. It was concluded that the supplementation of minerals and vitamins play an important role in establishment of estrus and overall conception rate when compared to hormonal (Ovsynch) therapy alone.
