Forty-five Hisex commercial layers and forty-five local Saudi breed layers were used to determine the acceptable limit of short-term water restriction in the late phase of production, when the problem of high feed and water consumption is expected. The experiment was performed under hot and arid environmental conditions when the layers were at fifty weeks of age. Layers from each breed were ran...

Longissimus muscle area, shear force measure, and sensory panel scores for flavor, juiciness, and tenderness, and marbling score were obtained from 682 steer carcasses, resulting from crosses among five Bos taurus and Bos indicus breeds. The single-trait model used included birth year and as covariates breed fractions, weaning age, and days on feed. The numerator relationship matrix was for 1,3...

BACKGROUND Anecdotal beliefs and limited research suggest variable patterns of mortality in age, size, and breed cohorts of dogs. Detailed knowledge of mortality patterns would facilitate development of tailored health-maintenance practices and contribute to the understanding of the genetic basis of disease. HYPOTHESIS/OBJECTIVES To describe breed-specific causes of death in all instances of ...

background and aims: finding prevalence of chicken anemia virus (cav) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. in this paper we attempt to describe molecular detection of chicken anemia virus in native larry-breed chickens in chaharmahal-va-bakhtiyari province in iran for the first time. materials and methods: blood samples were collecte...

the booroola fecundity gene (fecb) and growth differentiation factor 9 (gdf9) gene belong to the transforming growth factor β (tgf-β) superfamily. the mutations of these genes have additive effects on the prolificacy in sheep. the aim of the present study was to determine the possible mutations of fecb and fecgh genes in lory sheep breed of the lorestan province, iran. sixty blood samples were ...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...
