Abstract

The effect of exogenous insulin treatment alone and in combination with progesterone (P4) on ovarian response as well as blood glucose and progesterone-profile was studied on 28 acyclic dairy cattle, divided randomly into 4 groups i.e. insulin (group1),P4(group 2), insulin plus P4 (group 3) aud control (group 4),each comprising 7 animals. Cows of the insulin treatment group were injected subcutaneously long acting purified bovine insulin at @O.25IU/kg body weight/day for 5 consecutive days. Cows of P4-treatment group injected intramuscularly with 17- hydroxy progesterone at dose @50mg/day for 5 consecutive days. Ttle cuws of insulin+Pd- treatrnevt group injected insulin for 5 consecutive days. The cows of insulin+P4- treatment group injected insulin for 5 days similar to group 1 followed by P4-for next 5 days. Cows of gr 4 kept as untreated control. The induction of estrus was higher in insulin treated cows (85.7%) as compared to P4 (42.85%). insulin+P4 (42.85%) and control (14.3%). The difference was statistically significant between group 1 and control. Overall conception rate was 40%and 33.3% in groups 1 and 3, respectively. one got conceived in group 2 and control. The plasma glucocsoe concentration was at the normal level before start of treatment, did not differ along the groups during different days with averages ranging from 43.500±1.552 to 53.280±4.653 mg/dl before and after the treatment. Serum progesterone concentration before start of treatment ranged between 0.45±0.072 to 0.765±0.187 ng/ml confiring the state of anoestrus. The P4 concentration was lowest at estrus 0.020±0.00 to 0.256±O.O86ng/ml.Thereafter, on day 10th post estrus it increased significantly in insulin treatment group (7.115±0.723 ng/ml) as compared to P4 (4.903±2.718 ng/ml). insulin+P4 (4.89O±O.480 ng/ml) and control (3.59±0.00 ng/ml) (P&gtO.O1). The results demonstrated beneficial effcct of insulin on ovarian function and restoration of fertility in acyclic dairy cattle.
