Abstract

The present study included two experiments, the first experiment aimed to test if direct supplementation of P4 during post insemination period together with GnRH treatment on day 11post-isemination (PI) improve conception rate or not. The second experiment aimed to test whether peri-insemination feeding on fatty acids supplemented feed could improve conception rate or not. Cows in experiment 1 (n= 96) were fed on the basal diet (B) and randomly allotted into 3 groups vz: G1B (n=34) whereas cows received intravaginal insertion of CIDR (controlled internal drug release device) on Day 1 PI whereas Day 0 was the day of insemination plus single I/M injection of GnRHa (0.02 mg buserelin, Receptal) on Day 11 PI. The second group G2B (n=30) received the same treatment regime of G1B plus 2 injections of 250mg of progesterone (Cidolut-Depot) on Days 1 and 3 PI. The 3rd group (G3B, control n=32) received no treatments. The results of the present study showed a decrease in the conception rate in both G1B and G2B although there was a significant increase in the serum P4 concentration on Day 3 and 8 PI compared with the control. In contrast there was a significent increase (P<0.01) in the CR in cows fed fatty acids supplemented feed compared with the control (75 vs 62.5%). It could be concluded that one of the beneficial effects of peribreeding feeding cows on fatty acids supplemented feed is enhancing endogenous progesterone secretion which is being better than direct exogenous progesterone supplementation in improving conception rate in moderate yielding dairy cows.
