Abstract: Anestrus poses substantial challenges for dairy industries worldwide. This research aims to evaluate the effect of oral supplementation with garlic alone, vitamins A, D 3 , E alone, and their combination on heat detection, pregnancy rate and serum profile in anestrus dairy cows. Using a completely randomized design, this study, conducted over 327 days, evaluated 72 anestrus-affected cows, which were divided into four groups. T 0 (Control) received only normal saline; T 1 with vitamin A,D 3 ,E; T 2 with Garlic and T 3 integrated with A, D 3 , E + Garlic in drinking water. Results demonstrated that the treatment groups exhibited significantly higher estrus signs ( p < 0.05) compared to the control. The pregnancy rate was also increased ( P = 0.059), especially in the T 3 group which had the highest heat detection (55.55 %), conception (70 %), and pregnancy (38.88 %). In comparison, the heat detection rate for T 1 was 44.44 %, while the conception rate for T 2 was 66.66 %. Additionally, T 0 exhibited the least proportion across all parameters. Additionally, the elevated BUN (Blood Urea Nitrogen) and blood glucose levels observed in non-responsive (those not showing signs of heat) cows at 32.51 and 43.65 mg/dl respectively, compared to responsive cows (those showing signs of heat) with levels of 22.40 and 51.34 mg/dl. These findings suggest a potential association between these blood parameters and the cyclicity of dairy cows. These findings highlight that oral supplementation with vitamin AD 3 E+Garlic significantly improves the heat detection rate and pregnancy rate than only administering vitamin AD 3 E or Garlic with anestrus in dairy cattle.
