Data from the birth weight (BW), the average daily gain from birth to weaning (ADG) and the weaning weight (WW) of 1182, 1099 and 1099 lambs were respectively collected and applied to estimate the maternal effects on heritabilities as well as on the determination of the environmental factors. The data were collected from Shahrbabak Sheep Breeding Research Station within five year, from 1993 to ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
the objective of the present study was to determine polymorphism within the promoter region of somatotropin receptor genes in indigenous sistani cattle (bos indicus) and associations between this polymorphism and breeding value of birth weight. the pedigree structure was included by considering 1173 animals with 600 progeny birth weight data obtained from a zhark breeding station in sistan and ...
BACKGROUND Susceptibility of sheep to scrapie infection is known to be modulated by the PrP genotype of the animal. In the Netherlands an ambitious scrapie control programme was started in 1998, based on genetic selection of animals for breeding. From 2002 onwards EU regulations required intensive active scrapie surveillance as well as certain control measures in affected flocks.Here we analyze...
Baluchi sheep is the dominant fat-tail breed in Iran. We studied the microbial communities in the rumen of four Baluchi lambs fed a high concentrate conventional diet. Using DNA extracted from the rumen samples, we found the partial ribosomal rRNA of bacterial and archaeal were amplified by polymerase chain reaction (PCR). The amplicons were sequenced using 454 Titanium pyrosequencing and the d...

Reproductive records of 5327 Zandi ewes were collected from a research flock at the Zandi sheep breeding from Varamin station during 1991-2011. Genetic parameters were estimated for main traits such as conception rate (CR), number of lambs born (NLB), number of lambs at weaning (NLW) and the composite traits including number of lambs born per ewe exposed, number of lambs weaned per ewe exposed,...
in this research, 6517 records, collected by khojir sheep breeding station (tehran, iran), during 1991 to 2011 were used to estimate genetic parameters of lamb survival in zandi sheep. genetic parameters were estimated using 16 different models of animal model, sire and threshold models using reml procedures. the aic criterion was used to evaluate the models. the effects in the most suitable an...
Animal breeding reports in the Journal of Animal Science (JAS) and in its predecessor, Proceedings of the American Society of Animal Production, were counted and categorized. In 22 volumes of the Proceedings of the American Society of Animal Production, 155 articles had animal breeding content, of which 54% were research reports, 17% extension communications, and 28% syntheses or reviews. Sever...
