Abstract Sustainable agriculture approaches necessitate a concerted effort from researchers to establish paths that meet global population needs without compromising environmental resources. Goats are unique among ruminants because of their ability adapt some the harshest environments around world. Growth Hormone (GH) gene is major regulator muscle mass growth. Therefore, our study aims analyze whole sequence GH in order identify various single nucleotide polymorphisms (SNPs) Damascus and...
Abstract The study assessed the quality and variability of camel hair fibres in arid regions Egypt. Raw camel-hair samples were collected from fifteen Sudanese camels divided into seven males (414.60 ± 38.19 kg, BW) eight females (401.67 26.76 kg BW), investigated influences animal sex on both physical chemical traits fibers. relationships among properties mineral amino acid content studied. Camel’s had no significant effect any studied including fibre diameter (FD), prickle factor (PF),...
Four ultrasound measurements were used to establish prediction equations predict weight of carcass components forty five Egyptian ram-lambs at 12 months age.The depth, width, area eye muscle (Longissimus dorsi) and thickness fat covering the th 13 ribs area.Data analysed by least squares procedure General Linear Model (GLM) using SAS statistical package (SAS, 2004) simple correlation coefficients calculated.Correlation between Longissimus dorsi positive significant in Barki (0.55) Rahmani...
Five body measurements of 45 ram-lambs from Barki, Ossimi and Rahmani fat-tailed breeds (15 each) were recorded at slaughter 12 months age to predict weights live hot carcass.The length, height withers, heart girth, paunch girth leg circumference.Simple correlation coefficients between with weight carcass traits calculated.The stepwise procedure was used select the variable for prediction equations composition.In ram-lambs, significantly correlated most measurements, while in Barki only...
The animal gastrointestinal tract contains a complex microbiome whose composition ultimately reflects the co-evolution of microorganisms with their host and host’s environment. This study aimed to gain insights into adaptation microbiota local Egyptian cattle three different ecosystems (Upper Egypt, Middle Lower Egypt) distributed across 11 governorates (with an average 12 animals per governorate) using amplicon sequencing. We analyzed from 136 fecal samples through 16S rRNA gene sequencing...
Seven-hundred kilograms of subtropical Barki wool was collected to study the effect a subjective grading system and blending with polyester on selected yarn characteristics. Wool graded subjectively into coarse, fine raw; then each grade blended 0%, 15%, 25%, 35% 45% polyester. Staple strengths were higher in both coarse grades compared raw wool. elongation reached 3 times that twice as much grade. Also, 100% blend, grades. The had highest friction, followed by other Generally, adding led an...
Forty five Egyptian ram lambs, 15 of each Ossimi, Barki and Rahmani were used to investigate the influence breed body weight on fat tail measurements carcass composition.Fat also establish prediction equations predict weights (FTW), dissected total (TBF).Fat upper (UFTT) lower (LFTT) thickness, (UFTW) (LFTW) width, (UFTC) (LFTC) circumference as well length (FTL).Body (BW), Empty (EBW), hot (HCW), pericardial weight, omental mesenteric perinephric pelvic recorded.The left half carcasses into...
Linear body measurements and real-time ultrasound may serve as crucial factors in cost-effective carcass prediction, thereby facilitating value-based marketing of living animals. The current study aimed to evaluate components cuts male Damascus kids from measurements. Besides investigate the effect presence horns type birth (single or twins) on characteristics. Thirteen aged 12 months were used study. Ultrasound taken with probe (7.5 MHZ) between 12th 13th thoracic vertebra live kids.Body...
This study assessed the impact of oral administration zinc oxide (ZnO) and selenium (Se) nanoparticles on milk production gene expression in Baladi goats. Twenty-two pregnant females, 30 days before parturition, were divided into five groups: Group 1 (n=4) served as control; Groups 2 3 (n=4 each) received 150 mg ZnO 0.3 Se microparticle (MP) forms, respectively; 4 5 (n=5 15 0.03 nanoparticle (NP) respectively. Milk yield, composition, related to analyzed. Results indicated a significant...
Twenty eight Barki ewes with their lambs were used to examine the effect of blackening a part (whole body except head, rump tail,around eyes and head) or whole on maternal responsiveness (white breed) during 2 nd week after lambing.Ewes separated (50 m away from each other) for 4 hours before test period.Behavioural displayes dams recorded 10 min when introduced dams.Blackening reduced significantly (P< 0.01) number acceptances at udder compared unblackened ones.Number rejections was...
In the present study, 700 Kg of Egyptian Barki sheep wool was collected from farms Desert Research Center, Egypt, to study effect subjective grading system and blending with polyester on some yarn characteristics. Wool graded subjectively into coarse, fine raw, then added each grade at following percentages (0%, 15%, 25%, 35% 45%) make wool-polyester blends. Staple strengths were greater in both coarse grades compared raw wool. elongation reached 3 times twice as much grade. Also, 100%...
