abstract
The present work was conducted to investigate the induction of estrus in randomly selected non lactating ewes during the non breeding season at the Govt Sheep Breeding Farm Panthal, Katra, Reasi, Jammu (J&K). Five groups (GI, GII, GIII, GIV,GV) were made from the 30 selected ewes, each group having 6 ewes (n=6), which were covered under different hormone protocols as (GI= 1/3 Norgestomet + 200 IU PMSG, GII=1/3 Norgestomet + Ram effect, GIII= P₄ sponge + PMSG 200 IU, GIV=P₄ sponge + Ram effect, GV=untreated control). All the ewes (100 %) treated with different hormonal protocols exhibited induced estrus. In conclusion, the biochemical parameters viz, Glucose, Calcium and Phosphorus levels increased significantly (P<0.05), while as Cholesterol, Albumin increased non significantly (P>0.05) and Globulin decreased significantly (P<0.05) at induced estrus in all the treatment groups (GI, GII, GIII, GIV). In the untreated control (GV), none of the ewes exhibited estrus, hence no sampling was done on that day.
