This study was carried out to evaluate the effect of high dietary energy as dry fat and protected methionine on growth efficacy, feed intake and efficiency and carcass parameters of Awassi lambs during finishing stage. Twenty four Awassi lambs (3-4 months old) were distributed equally into four treatments groups as follow: Control (NRC requirements); T1 (High energy 3.0 Mcal ME/kg); T2 (high en...

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...

The effect of rumen-protected methionine (RPM) was investigated in Awassi ewes (0, 3 or 5 g/head/d, n = 20) on reproductive and productive performance (initial body weight [BW] 70.9 − 71.8 kg, years). Supplementation started with the flushing feeding regime (at breeding time) lasted for 42 d. RPM reused during last 60 d pregnancy first lactation. increased (p < .05) progesterone concentration a...

Background: Sheep milk production after weaning is produced for a limited period of 80-100 days, it used cheeses manufacturing, especially in the Mediterranean region due to its high content total solids and preferred human nutrition because rich unsaturated fatty acids, protein, nucleotides nucleosides, this earns therapeutic functions cancer prevention. On other hand, reducing cost feeding im...

Abstract The study was conducted in the animal barn of Agricultural Research Department/ Nineveh Department / Ministry Agriculture during period 1/3-15/4/ 2022, using 18 Awassi ewes last stage milk production (after weaning). ages ranged between 3-4 years and their average weight (46.80 ± 1.33 kg) were divided into three groups. first group considered control (T1) fed on standard ration without...

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...

Two experiments were conducted to study the efficiency of ovine follicular fluid (OFF) and age ewe on in vitro nuclear maturation Awassi sheep oocytes (Experiment 1) subsequent stages early embryos their quality 2). The OFF has been added basic medium (TCM-199) with three different levels (A: 0% (Control group), B:15%, C:25% D:50%) while ages ewes determined into two main groups (&gt; 2 1-2 yea...

Abstract The goal of this research was to determine the effects various doses flaxseed oil on ewe body weight, growth characteristics, and selected biochemical hormonal blood characteristics. This carried out in animal science department at University Tikrit’s College Agriculture between October 6th, 2022, September 1st, 2022. There were a total 17 female Awassi sheep, ages 1-2, with an average...

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...

Societal and scientific challenges foster the implementation of the ecosystem approach to marine ecosystem analysis and management, which is a comprehensive means of integrating the direct and indirect effects of multiple stressors on the different components of ecosystems, from physical to chemical and biological and from viruses to 5 fishes and marine mammals. Ecopath with Ecosim (EwE) is a w...
