Awassi and Assaf are local Israeli sheep breeds with prolificacies of ~1.30 and ~1.65 lambs born/ewe lambing (LB/EL), respectively. Introgressing the B (Booroola) allele of the FecB locus into these breeds led to the formation of prolific strains designated 'Afec Awassi' and 'Afec Assaf', in which lamb production under both intensive and semi-intensive conditions is higher than in the respectiv...

characteristic of the udder, milk traits and their relationship were investigated in 32 awassi ewes raised in a commercial flock. commencing one month after lambing milk yield was recorded at monthly intervals until the ewes were dried. also, the udder traits were measured, including udder width, udder circumference, udder length, distance between teats and length and diameter of both teats. re...

This study was performed to investigate the effect of beta carotene-vitamin E and hCG treatments alone or a combination both on fertility in estrus syncronized Awassi ewe lambs. A total 103 lambs were divided into four groups before study. Lambs treated with progesterone sponge for 12 days, PGF2α two days removal, 600 IU PMSG removal day 150 mating. The control group (n: 25) did not receive any...

To study the impact of body condition score (BCS) ewes on weight (BW) and gain (BWG) lambs effect weaning age BW BWG lambs, thirty Awassi (2–3 years old) with their borne male were used in study. Ewes condition-scored assigned to three groups, 1st, 2nd 3rd groups BCS 2.5, 3 3.5 respectively. Lambs weaned neither 60 or 90 days (5 for each), lasted days. The analyzed data showed significant (P≤0....

The development of an efficient and practicable method for transcervical collection of embryos in Awassi ewes to the improvement of embryo recovery was investigated. Twentyfour non-pregnant Awassi ewes of 3-4 years of age were randomly allocated into two groups (n = 12). Each ewe was treated with a progesterone impregnated intra-vaginal sponge for 12 days. The following superovulation treatment...
