Resumption of ovarian and oestrous activity of Black Thibar ewes post partum: influence of nutritional level and duration of suckling



Resumption of ovarian and oestrous activity of Black Thibar ewes post partum: influence of nutritional level and duration of suckling



Annales de l' Institut National de la Recherche Agronomique de Tunisie 60(12): 16



80 Thibar ewes that lambed in Oct. were fed ad lib. with or without a supplement of 200 g concentrates per day after lambing. Lambs were weaned at 45 or 90 days of age. Ovulation rate (1.2-1.5 for 1st ovulation, and 1.7 for the 2nd ovulation), interval from lambing to ovulation (22.8+or-10.2 to 31.2+or-13.5 days), or interval from lambing to overt oestrus (52.7+or-13.2 to 65.9+or-12.7 days) were not significantly affected by supplementation or age at weaning.
