introduction: sheep has played an important role in meat production and income generation in iranian farming systems. their profitability, however, is highly depended on nutrient supply. drinking water is major nutrient that is responsible for different utilization of nutrients and thereby productivity and gain of animals in most parts of the world. inadequate water and its quality such as sali...

in this study 21721 pedigree records of iranian baluchi sheep registered during 30 years (1979 to 2008) at abasabad breeding station were used to estimate pedigree completeness level, inbreeding and average relationship coefficients of animals. during the studied years pedigree completeness level has a positive trend with the most recent cohort of lambs born in 2008 having pedigrees with 6.2 eq...

Genetic parameters for birth weight (BW), weaning weight (WW), 6 months weight (6MW), 9 months weight (9MW) and yearling weight (YW) in Baluchi sheep were estimated using data collected during a 26-year period (1984-2010). Estimates of (co)variance components were obtained by REML procedures by fitting a linear mixed animal model. Significant random effects for each trait were explored by fitti...

introduction a major constraint of animal production in south of iran is the lack of cheap source of roughages. date palm leaves (dpl) is one of the most abundant agricultural by-products in south of iran. almost all pruned leaves are discarded in the fields, mainly for nutrients recycling and soil conservation (m. wan zahari, et al1999). the yearly maintenance of date palm tree produces a (aro...

litter size is one of the most important economical traits in sheep breeding industry. in addition to minor genes, litter size is under the influence of major genes. bone morphogenetic protein 15 (bmp-15), a member of the transforming growth factor beta (tgf-ß) superfamily, which is specifically expressed in oocytes, plays a dramatic role in sheep prolificacy. reported mutations in this gene ca...
