Introduction: The aim of the present study was to evaluate the morphometric differences of the skull in male and female Zell sheep. Methods: For this purpose, 30 heads (15 adult males and 15 adult female) of Zell sheep breed were collected from the local slaughter-house. The skulls were prepared using the boiling maceration according to the usual techniques, and the mandible was dissociated fr...

Myogenin gene (MYoG) affects the synthesis of muscle myofibrillar growth and increase of meat production. The myostatin (MSTN) gene is identified as a specific negative regulator of skeletal muscle growth. Reduction of the expression level of MSTN throughmutation in the sequence of this gene leads to an increase of myogenesis and regeneration of muscle cells during the postnatal growing period ...

Intrafetal insulin-like growth factor (IGF)-I promotes cardiac hypertrophy in the late-gestation fetal sheep; whether these effects are sustained is unknown. IGF-I was infused for 4 days at 80 microg/h from 121 to 125 days of gestation, and its effects at 128 days, 3 days after the infusion stopped, were determined by comparison with untreated fetal sheep. After IGF-I treatment, fetal weights w...

A survey was conducted in Southwestern, Punjab, Pakistan during two different seasons to assess the status of selenium of three different classes of grazing sheep. Blood plasma from lactating, non-lactating and male sheep were collected four times monthly in winter and summer seasons and analyzed for selenium concentration. Seasonal variations were found for plasma selenium concentration. Selen...

Some of the metacestodes are not only zoonotic but are also responsible for severe tissue damage, reduction in milk and meat production, and considerable economic loss due to condemnation of the infected organs of the herbivorous animals. The aim of the present study was to determine the prevalence of Cysticercus ovis, Cysticercus tenuicollis, hydatid cyst and Coenurus gaigeri in sheep and goat...

The male effect refers to the effect of the introduction of the male on the oestrus cycle of the seasonally anoestrus female. This effect is a neuro-hormonal response that is utilised by flock managers to improve the ovulation rate in females and shorten the breeding season. The introduction of males to the female flock will elicit this response but the use of vasectomised males is a common pra...

Twenty-four 21-day-old Balouchi male lambs were equally divided into two groups. Twelve subjects were artificially reared (AR), twelve others were ewe reared (ER) and used as control. AR in comparison of ER lambs maintained higher concentrations of blood betaHydroxybutyric acid (BHBA); however glucose concentration was not affected by rearing system. Unlike the DNA content and cell size, the RN...

The aim of this study is to determine whether or not the breed and sex factors have an effect on shape in mandibles Hamdani Awassi sheep. A total 31 were used. samples analyzed via geometric morphometric methods by using semilandmark. In study, it was determined that primary principal component accounted for 36.52% difference. According analysis, clustered significantly terms breed; whereas, th...

In December 2008, near Flaming Gorge Reservoir in northeastern Utah, a 2 1⁄2-yearold male Rocky Mountain bighorn sheep (Ovis canadensis canadensis) was reported in poor body condition with bloody lesions covering the muzzle area. The sheep was euthanized, and samples were submitted to the Utah Veterinary Diagnostic Laboratory in Logan, Utah. The gross and microscopic lesions confi rmed the diag...
