Objective(s) Staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. Antibiotic therapy for vancomycin resistant S. aureus (VRSA) can not promise the eradication of infections. Since adhesion is the major route of infections, adhesin based vaccine could suppress S. aureus infections. Fibronectin binding protein A (FnBPA) and clumping factor A (ClfA)...

to estimate the genetic parameters for production and reproduction traits in holstein cows, information from 15 herds recorded by animal breeding center of iran during 1980 – 2004, were employed. estimations were made using restricted maximum likelihood method under an animal model ranging df-reml and matvec software. estimates of heritabilities for yield traits were moderate and ranged from 0....

Reductionist approaches to food focus on isolated nutritional criteria, ignoring the broader physiological and societal benefits trade-offs involved. They can lead inadvertent or, potentially, intentional labelling of foods as good or bad. Both be considered worrisome. Among our present-day array issues is disproportionate stigmatisation animal-source harmful for human planetary health. The cas...

aflatoxins are toxic compounds which are produced by aspergillus flavus and a. parasiticus. these toxins can be transmitted into the animal body via contaminated feed. when these toxins enter the animal body, they can penetrate into different tissues. one of the most important tissues which can be influenced by aflatoxin is the mammary gland. milk protein is one the most important factors in de...

genetic trend for production traits were estimated in iranian holstein cattle using the first lactation data recorded by cattle breeding and dairy product improvement center of the state from 1991 to 2006. effect of some factors on genetic trend was investigated using data from 18 large herds. (co) variance components and genetic parameters were estimated, using five trait animal model and em-a...

to estimate the grazing capacity in each region it is necessary to determine animal requirement based on forage quality and animal unit weight of dominant sheep breed. in present study animal unit weight of farahani sheep breed was investigated. two herds were selected. thirty animals including 15 three and four years' old ewes, 5 nine months old lambs, 5 six months old lambs, 5 three and four ...
