the aim of this study was to estimate the genetic trend and genetic parameters of survival traits in baluchi sheep using survival records from 27978 baluchi sheep, which were collected by the animal breeding center of iran during1979 to 2009. genetic parameters of lamb survival from 1 to 400 days of age and from 1 to the last recording date. traits were estimated using animal model (with or wit...

the objectives of this study were to identify a suitable mathematical model for describing the growth curve of baluchi sheep based on monthly records of live weight from birth to yearling; and to evaluate the efficacies of nonlinear mixed effect model (nlmm) and the nonlinear fixed effect model (nlm) methodologies. growth models were fitted to a total of 16,650 weight–age data belonging to 2071...

regions on three ovine chromosomes (oar1, oar5 and oar25) were selected to study quantitative trait loci (qtl) segregating for wool traits in baluchi sheep. a total of 503 progeny from 13 half-sib families were genotyped for 15 microsatellite markers. the average number of progeny per sire was 38 and ranged between 16 and 59. data were collected from research centre on baluchi breed in 2009 and...

the poly morphism of 4 micro satellite loci (bms1350, lgb, ilsts45, bms1915) associated with functional traits were evaluated for detecting the diversity level in baluchi breed of sheep. one hundred eighty five blood samples were collected from sheep herd in abbas-abad breeding station. dna extraction was performed using guanidinethiocyanate silica gel method. gene fragments of micro satellites...

An experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and UT-B expression in growing Baluchi male lambs. Four Baluchi male lambs [30 ± 2 kg BW] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. The treatments fed forage: concent...

Short rib-polydactyly syndromes (SRPS) are a heterogeneous group of recessively inherited lethal skeletal dysplasias. Four types have been recognised. However, overlap in the clinical and radiological features of the four types has led to difficulties in distinguishing between them. The congenital infection-like syndrome is an autosomal recessive syndrome characterised by mental retardation, mi...
