nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...

Sheep in Ethiopia are adapted to a wide range of environments, including extreme habitats. Elucidating their genetic diversity is critical for improving breeding strategies and mapping quantitative trait loci associated with productivity. To this end, the present study investigated the genetic diversity and population structure of five Ethiopian sheep populations exhibiting distinct phenotypes ...

Objective: Various practical methods have been used for pregnancy diagnosis in sheep. Methods of pregnancy diagnosis depending on visualization of the conceptus or determination of its secretory products in the maternal blood or in the milk are the most accurate and specific methods for pregnancy. In 1980, B-mode ultrasonography was introduced in the veterinary field and used for pregnancy diag...

introduction: inappropriate body composition represents impaired energy and nutrient intake and can be a risk factor for many diseases, especially for cardiovascular disease. different methods have been suggested for the estimation of body fat volume and its distribution. however, they may be either expensive or hazardous for some groups of patients. sonography is a very accessible technique, w...

ninety six pairs of adrenal glands from lori – bakhtiari sheep and goat, aged 6 month to 1 year and 1 – 1.5 year from borujen abattoir were collected. after collecting the glands and weighting them, some parameters such as: length, wide and thickness of left and right side by caliper device were measured. in histological studies, after tissue preparation and staining with h&e;, cortical zones a...

For this study, 24 Lori-Bakhtiari sheep were selected and divided into four age groups: 1-10 days, 5-8 months, 1-2 years and 3 and more years. In each age group, six animals (3 of each sex) were used. The specimens of eight different skin regions were collected. They were fixed in 10% formaldehyde solution and processed through routine paraffin embedding, cut at 5-7 μm and stained with haematox...

background: babesia ovis and theileria ovis are among the important and main etiological agents causing ovine babesiosis and ovine theileriosis, causing severe economic losses among sheep and goats. the aim of the present study was to determine the prevalence and molecular diagnosis of b. ovis and t. ovis in lohi sheep at livestock experiment station bahadurnagar, okara, pakistan. methods: the ...

to study the effects of environmental factors on milk and fat yields (240day) traits of iranian buffaloes, 22596 and 22165 records were utilized for milk and fat yield traits, respectively. uni and bivariate analysis for estimation of (co)variation components of the traits were done in five lactations. milk yield in the 1st lactation had the highest number of records (4482), collected through c...

BACKGROUND HLA genes are highly polymorphic and certain alleles are frequent only in specific populations. Therefore, HLA is a unique tool for studying the genetic relation between different populations. Iranians are ethnically diverse people and one of the major ethnic groups in Iran is Lur population inhabiting along the central and southern parts of Zagros Chain Mountain. OBJECTIVE Genetic...
