introduction kurdish sheep breed is one of the most important native breeds of iran. they are fat-tailed, large-sized, well adapted to the mountainous regions in northern khorasan province and mainly raising for meat production under pastoral production system (28). feed efficiency is a major component in the profitability of the small ruminant enterprise, because quality of range and pasture i...

in this study, 100 moghani sheep from breeding station located in jaafarabad, moghan were genotyped for exon 1 of igf-i gene, using pcr-sscp. different band patterns were obtained in this site gene that was studied. based on sscp patterns, three genotypes bc, bd and bb obtained with frequencies of 65%, 26% and 9%, respectively. the genotype frequencies had a significant deviation from hwe. in a...

The selection of animals with lower production costs can be achieved by using feed efficiency and growth curve information. Kleiber ratio (KR) is an alternative option for discriminating against the that have greatest weight gain about their final weight. Alternative curves ostriches African Black (AB) Red Neck (RN) breeds crossbreeds (CB) were investigated KR Gompertz equation. Univariate mult...

Objective: Estimation of genetic parameters for Kleiber ratio (KR) and genetic trends for pre-weaning weights of Arabi sheep has not been previously conducted.Methods: Data and pedigree information were collected at the Khuzestan Ramin Agricultural and Natural Resources University, Animal Science Research Station, located in southwest Iran, from 2001 to 2008. (Co)variance components and corresp...

The objective of the present study was to evaluate the effects of inbreeding on average daily gains and Kleiber ratios in Moghani sheep. Traits included average daily gain from birth to 3 months (ADG1), average daily gain from birth to 6 months (ADG2), average daily gain from 3 months to 6 months (ADG3), average daily gain from 3 months to 9 months (ADG4), average daily gain from 3 months to ye...
