introduction in recent decades, a large variety of science experts, including geology and mine scientists, have considered remote sensing technology as one of the most important instruments to receive information. access to hyper spectral data is one of the main evolutions in the remote sensing technology. the main feature of the technology is its application in identification of minerals and d...

evaluation of gastric emptying rate using nuclear scintigraphy as the gold standard method has been studied in various animals, but there is no report in suckling lambs. the aim of this study was to develop a nuclear scintigraphic method to visualize and measure abomasal emptying rate by estimation of scintigraphic half emptying time (t1/2) in the live neonatal lamb. five healthy, female irania...

Objective: The aim of the present study was to evaluate artificial insemination techniques on reproductive performance in Ghezel ewes synchronized with CIDR during breeding season. Methods: All ewes were treated with controlled internal drug release device (CIDR) inserted into the vagina of the ewes for 14 days. All ewes were treated a single intramuscular (IM) dose of PMSG was injected. In thi...

This study aims at investigating the effectiveness of nutritional supplements containing vitamins, minerals, and ammonia on the sexual and breeding behaviors in Ghezel sheep. To this end, 28 three and half-year old ewes (50±3 kilograms) with the record of giving birth to two lambs and 4 three-year old (90±3.5 kilograms) rams were used. The ewes were divided into two groups of A (i.e., treatment...

Genetic variation among sheep breeds in resistance to gastrointestinal nematodes (GIN) has been demonstrated in several production environments. Relationships between the ovine major histocompatibility complex and resistance to GIN have been studied, but few studies have systematically examined this issue in less-developed and semi-arid regions. The aim of the current study was to explore assoc...

this survey was carried out to determine the infection rate of coenurus cerebralis in urmiaabattoir, west azerbaijan, iran. a total of 402 sheep heads were examined and the number ofc. cerebralis cysts per each head was recorded. thirty three sheep heads were examined eachmonth during 12 months from 2006 to 2007. of 402 heads, a number of 75 heads (18.65%)were infected with c. cerebralis. the c...
