Optimum dietary crude protein level for finishing Awassi lambs.
Awassi is a multi-purpose sheep breed. Awassi lambs being finished are usually offered an 18% crude protein (CP) diet. The growth rate of Awassi lambs is lower than other meat breeds. Therefore, this high content of dietary CP is questionable. The objective of this study was to estimate the optimum CP level for finishing Awassi lambs. Fifty male Awassi lambs (23.0+/-1.2kg) were fed five high co...
متن کاملComparative performance of Awassi lambs and Black goat kids on different crude protein levels in Jordan.
An experiment was conducted to investigate the effect of different crude protein (CP) levels on the growth performance of Awassi lambs and Black goat kids. Forty lambs and 40 kids were randomly selected and allocated to separate pens of equal size for 75 days. Each group was fed one of four rations containing 12, 14, 16, or 18% CP. Final weights and gains for lambs were higher (P<0.001) than th...
متن کاملIncreasing Prolificacy of Awassi and Assaf Breeds by Introgression of the Fecb (booroola) Mutation: Achievements and Challenges
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...
متن کاملEffects of Castration on Penile and Urethral Development in Awassi Lambs
The objective of this study was to determine the effect of castration on penile and urethral development in Awassi lambs. Twenty 1−2-weeks old Awassi lambs were divided randomly into 4 groups. Groups 1, 2, and 3 were castrated at 2 weeks, 3 and 5 months of age, respectively. Group 4 was not castrated (control). To assess penile and urethral development, penile length, penile diameter and urethr...
متن کاملEffects of feeding different levels of sesame oil cake on performance and digestibility of Awassi lambs
This experiment investigated the effect of feeding different levels of sesame oil cake on the intake and digestibility of DM, CP, crude fiber, and crude fat in Awassi fattening lambs. Sesame oil cake was incorporated into lamhs’ rafions at levels of 10 and 20% to replace similar percentages of barley and soybean. The results showed that the high level of sesame oil cake inclusion decreased DM a...
