pasteurella multocida is known as one of the main organisms causing pneumonia in sheep. as immunity in pasteurellosis is serogroup specific, identification of prevalent capsular group among endemic areas is essential. the aim of this study was to molecular identification and determine of the capsular type of the p. multocida strains isolated from sheep pneumonia in iran. bacteriological and bio...

b) Numbers. The total sheep population in the Chokla distribution area was 0.53 m according to the 1972 census and 0.511 m according to the 1977 census, thus showing a slight decline. Of these, adult males and adult females were 0.049 and 0.352 m respectively. Chokla is perhaps the finest carpet-wool breed, although most Chokla wool is now being diverted to the worsted sector because of the dea...

Sheep display a variant phenotype with respect to their susceptibility to copper and derivative pathology. The North Ronaldsay sheep are acutely sensitive to environmental copper while the Cambridge breed is much more copper-tolerant. A study of protein expression in the liver of the two different breeds of sheep as a result of copper challenge would aid in the understanding of their differing ...

The agouti signaling protein (ASIP) gene has a crucial role in pigmentation by encoding that binds the melanocortin 1 receptor and stimulates synthesis of pheomelanin rather than eumelanin. Several studies have suggested an increased copy number ASIP might explain white certain goat breeds, as previously demonstrated sheep. In current work, we identified segregation CNV Murciano-Granadina (blac...

in this study, production, reproduction, managerial, and economic parameters obtained from data recorded for lori-bakhtiari flock of sheep (500 heads of breeding ewe) stationed at the sheep's breeding station, were employed to determine the relative economic values of and breeding objectives for an annual cycle of production, in village system in this breed of sheep. economic value for a t...

Domestication and the subsequent selection of animals for either economic or morphological features can leave a variety of imprints on the genome of a population. Genomic regions subjected to high selective pressures often show reduced genetic diversity and frequent runs of homozygosity (ROH). Therefore, the objective of the present study was to use 42,182 autosomal SNPs to identify genomic reg...

Introduction: Brucellosis is a zoonotic disease caused by the members of the genus Brucella. This bacterium is transmitted to humans through exposure to infected animals or via consumption of contaminated dairy products. Cultivation of the bacteria or amplification of its DNA using polymerase chain reaction (PCR) are conventional diagnostic approaches for definitive identification of Brucella i...

The Finnish Landrace (Finnsheep) is a well known high-prolificacy sheep breed and has been used in many countries as a source of genetic material to increase fecundity of local breeds. Analyses to date have indicated that mutations with a large effect on ovulation rate are not responsible for the exceptional prolificacy of Finnsheep. The objectives of this study were to ascertain if: 1) any of ...

Toxoplasma gondii infections in sheep and goats are important economically for public health many countries, including Romania. In this study, seroprevalence associated risk factors T. infection were determined 2500 500 from three counties the Banat region of Antibodies to found 1266 (50.64%) 375 (75%) goats, by using a commercial (IDEXX) ELISA. To evaluate epidemiological status infection, som...
