... Advances in molecular genetics have allowed the identification of genes that can enhance livestock production. The aim of this study was to investigate possible relationships between the calpastatin (CAST) Hha1 gene polymorphisms and growth performance, carcass characteristics, and meat quality in Awassi sheep. A total of 87 blood samples were collected from two-week-old Awassi ram lambs. The ampl ...
... A study was conducted to determine the effect of partial replacement of wheat straw by Atriplex halimus L. (ATR) on growth performance, nutrient intake, digestibility, carcass characteristics and meat quality of Awassi lambs fed finishing diet. Twenty seven Awassi ram lambs (initial body weight 14.9±0.54kg) were divided randomly into three dietary groups. Group one served as a control and received ...
... Quality food for human consumption will always be the aim for animal producers. Quantity and composition of fat deposits (fatty acid profile) strongly influences meat quality in ruminants, especially via increasing conjugated linoleic acid (CLA) concentration, which is known to have beneficial anticarcinogenic, antiatherogenic, antidiabetic and cholesterol reduction properties for human health. Aw ...
... The objective of this study was to evaluate the effects of replacing the protein source of soybean meal (SBM) with different levels of bitter vetch seeds (BVS) in the diets of finishing Awassi ram lambs on performance, and carcass characteristics. Diets were designed based on replacing SBM with BVS as a percentage of the diet. Diets were: control (0% BVS), substituting 5% of SBM (5% BVS), 10% of S ...
... A 70-d experiment was conducted to evaluate the effect of feeding poultry broiler litter (BL) at levels 0 (BL0; n=10), 100 (BL100; n=10), and 200g/kg (BL200; n=10) on performance and carcass characteristics Awassi lambs. Nutrient intakes [i.e., dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (aNDF), acid detergent fiber (ADF), and copper] were similar (P>0.05) bet ...
... Thirty-three Awassi lambs (18.0±0.86kg initial body weight; 75±2.21days of age) divided equally and were used in a completely randomized design to study the effect of partial replacement of barley grain by carob pods (CARP) on growth performance, carcass characteristics and meat quality. Treatment diets were no CARP (CON), 125g/kg CARP (CARP125), and 250g/kg CARP (CARP250) of dietary dry matter. A ...
... The aim of this experiment was to study the growth performance of both ram and ewe lambs, and the carcass characteristics of ram lambs of five genotypes: Awassi (A), F₁ Charollais-Awassi (CA), F₁ Romanov-Awassi (RA), B₁ Awassi-(Charollais×Awassi) (ACA) and B₁ Awassi-(Romanov×Awassi) (ARA). One-hundred lambs (50 females and 50 males) were separated into 10 groups according to sex and genotype from ...
... In the United Arab Emirates (UAE), several programs and centers have been established to study and evaluate halophytic and salt-tolerant plant communities. A large number of halophytic species, acquired from various parts of the world, have been evaluated and field-tested under salt and seawater irrigation regimes at UAE University and International Center for Biosaline Agriculture (ICBA). Among t ...
... An (Awassi × Merino) × Merino single-sire backcross family with 165 male offspring was used to map quantitative trait loci (QTL) for body composition traits on a framework map of 189 microsatellite loci across all autosomes. Two cohorts were created from the experimental progeny to represent alternative maturity classes for body composition assessment. Animals were raised under paddock conditions ...
... This study was conducted to evaluate the effect of feeding sesame hulls (SH) on growth performance and carcass characteristics of Awassi lambs. Twenty-one Awassi lambs (age of 70±4.53 days and initial body weight 18.6±0.53kg) were randomly allocated to 3 diets. Diet 1 served as a control and contained no SH (CON); diet 2 (low sesame hulls; LSH) and 3 (high sesame hulls; HSH) consisted of 12.5% and ...
... The objectives of this experiment were to evaluate the accuracy of ultrasonography to measure subcutaneous fat thickness (SFT) and LM traits (area, depth, and width) in live Awassi lambs of different sexes, predict actual SFT and LM traits without damage to the carcass, and improve carcass classification. Data were obtained from ultrasound scans of 20 female and 10 male lambs. Female lambs were ra ...
... Thirty Awassi ram lambs were used to study the effects of slaughter weight on carcass characteristics. Lambs were slaughtered at three different live weights (20, 30, and 40 kg). Empty body weight, hot and cold carcass weights and non-carcass components increased (P <0.001) at a steady rate between all slaughter weights. Body length, leg length, maximum shoulder width, width behind shoulders and g ...
... Nutrient intake, diet digestibility, N balance, carcass characteristics, and meat quality were evaluated in Awassi lambs fed different levels of sesame meal (SM). Twenty-seven Awassi lambs of similar weight (BW=18.8±0.74kg) and age (65±1.09 days) were equally divided into three treatments and fed individually high concentrate diets for 60 days. Group one served as a control and did not receive SM ...
... Twenty-three male Awassi lambs (initial body weight; BW=18.5±1.72kg) were individually housed to study effects of using yellow grease (restaurant fat) on lamb performance, nutrient digestibilities and carcass characteristics, and to compare such effects with soybean oil (SO). Lambs were randomly assigned to one of three dietary treatments: no added fat (control; CTL, n =7), 32g/kg of yellow grease ...
... Two experiments were completed to examine effects of inclusion of a yeast culture (YC) to a diet based on barley grain and wheat straw on digestibility, growth and meat traits of Awassi lambs and Shami goat kids. Experiment 1 studied effects of YC on apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and N b ...
... Twenty-one Awassi male lambs were used to evaluate the effect of replacing barely grains by Prosopis juliflora pods (PJP) on growth performance, digestibility, and carcass and meat characteristics. Lambs were fed finishing diets and assigned randomly to one of three dietary treatments. Treatment diets were no PJP (CON; n =7), 100g/kg PJP (PJP100; n =7), and 200g/kg PJP (PJP200; n =7). Dry matter ( ...
... The experiment was carried out to evaluate the effect of common vetch seed (CVS), used at various levels (0, 15 and 25%), as a protein source in diets replacing different proportion of barley, wheat bran and soybean meal on fattening performance, carcass and meat quality characteristics of Awassi male lambs at approximately 8 months of age. The lambs were divided into three treatment groups, T1 (c ...
