background: the aim of this study was to evaluate the functional capacity of the liver based on the activity of specific enzymes and bilirubin in serum and also to investigate the influence of mechanical and toxic effects of fasciola hepatica on the structures of the blood vessels and biliary tract in the sheep liver. methods: blood samples and liver of 63 indigenous sheep of pramenka breed, sl...

four saudi arabian indigenous sheep populations including najdi, hbsi, arb, and naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (fao). this study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. all loci were polymorphic in all populations and loc...

The aim of the pilot study was to evaluate slaughter characteristics and carcass composition of indigenous long fat tailed sheep and Small East African goats purchased from the auction markets slaughtered at 1.5 to 2 yrs of age and 20 kg to 25 kg live weight. The animals were slaughtered according to halal standard procedures. The left half carcasses were jointed into eight wholesale joints, an...

Genetic polymorphism at the β-lactoglobulin (β-LG) loci in indigenous sheep breeds (Tsigai, Racka, Pramenka) was determined. Altogether 904 sheep were genotyped for the presence of the A, B and C alleles of β-lactoglobulin by PCR-RFLP. The AB genotype was the most common and the β-lactoglobulin A was the most frequent in the Cokanski Tsigai (54%), while the B allele was the most common in the R...

myostatin gene or growth and differentiation factor-8 inhibits the puberty and development of skeletal muscles and it could change the size of some muscles such as double muscle, if the mutation occurs. one of the most important indigenous sheep in iran, lori sheep, possess high genetic potential for meat production. therefore, the study of some genes affecting meat production would be of utmos...

background: some species of grass cause poisoning and hepatogenous photosensitization in animals. objectives: feeding trials were conducted in sheep and goats to evaluate the hepatotoxic effects of setaria italica (s. italica). methods: twelve indigenous male sheep and goats were used in this study. the animals were kept outdoors against prevailing climatic conditions. they were fed with s. ita...

Arctic peoples today find themselves on the front line of rapid environmental change brought about by globalizing forces, shifting climates, and destabilizing physical conditions. The weather is not the only thing undergoing rapid change here. Social climates are intrinsically connected to physical climates, and changes within each have profound effects on the daily life, health, and well-being...

Immunocompetence of livestock plays an important role in farm profitability because it directly affects health maintenance. Genetics significantly influences the immune system, and the genotypic structure of modern fast-growing chickens has been changed, particularly after decades of breeding for higher production. Therefore, this study was designed to help determine if intensive breeding progr...

Borna disease (BD) is a sporadic neurologic disease of horses and sheep caused by mammalian Borna disease virus (BDV). Its unique epidemiological features include: limited occurrence in certain endemic regions of central Europe, yearly varying disease peaks, and a seasonal pattern with higher disease frequencies in spring and a disease nadir in autumn. It is most probably not directly transmitt...
