Effects of oxytocin on fertility of red sokoto goats treated with prostaglandin f 2á

Abstract

The objective of this study was to evaluate the effects of oxytocin (OX)  administration on conception rates in does. Red Sokoto (RS) does (n = 38) were equally allocated into 2 groups; I: does treated with prostaglandin plus normal saline (PGNS) and II: does treated with prostaglandin plus oxytocin (PGOX). Does were observed for standing oestrus behaviour and bred naturally using sexually active bucks. Results showed that oestrus response, conception and kidding rates were higher in the PGOX (73.7 %, 85.7 % and 58.3 %) than PGNS (63.2 %, 75.0 % and 55.6 %). Interval to onset of oestrus, duration of oestrus did not differ significantly (P < 0.05) between groups. We conclude that administration of oxytocin concurrent with prostaglandin F 2a enhanced oestrus response, conception and kidding rates of Red Sokoto does. Keywords : Red Sokoto does, oestrus, conception, kidding, oxytocin, prostaglandin F 2a L’objectif de cette etude etait d’evaluer les effets de l’ocytocine (OX) l’administration sur les taux de conception en fait. Red Sokoto (RS) (n = 38) ont ete egalement alloues en 2 groupes; I: ne traite avec prostaglandine ainsi une solution saline normale (PGNS) et II: ne traite avec la prostaglandine ainsi que l’ocytocine (PGOX). Est-ce que ont ete observes pour s’etre comportement de l’oestrus et eleves naturellement en utilisant mâles sexuellement actifs. Oestrus reponse, conception et kidding les taux etaient plus eleves dans le PGOX (73,7%, 85,7% et 58,3%) que PGNS (63,2%, 75,0% et 55,6%). Intervalle de debut de l’oestrus, la duree de l’oestrus ne differait pas significativement (P <0,05) entre les groupes. Nous concluons que l’administration d’ocytocine en meme temps que la prostaglandine F2a amelioree reponse, conception et kidding taux oestrus de Red Sokoto fait.
