polymorphism of some genes associated with meat-related traits in egyptian sheep breeds
نویسندگان
چکیده
the genetic polymorphism of some genes related to meat production in three egyptian sheep breeds (barki, rahmani and osseimi) was studied. the candidate genes were: calpastatin, myostatin, diacylglycerol-acyltransferase1, insulin-like growth factor binding protein-3 and booroola fecundity gene. the technique applied was the restriction fragment length polymorphism for the polymerase chain reaction products. polymorphism was found in the genes: calpastatin, myostatinanddiacylglycerol-acyltransferase 1, while no polymorphism was exhibited by the other two genes, insulin-like growth factor binding protein-3 and the booroola fecundity in the three breeds understudy. calpastatin locus digested with mspi had two genotypes mm and mn. the highest allelic frequency was for allele m. the same locus calpastatin digested with ncoi also exhibited two genotypes mm and mn. the nn genotype was absent with both the mspi and the ncoi enzymes in all breeds. myostatin digested with drai had two genotypes ab and bb. the aa genotype cannot be detected. the highest allelic frequency was for allele b. diacylglycerol-acyltransferase1 digested with alui showed two genotypes cc and ct. the highest allelic frequency was for allele c. the detected ct genotype might explain the moderate intramuscular fat content and muscle marbling in the egyption sheep breeds. each of the remaining two loci (insulin-like growth factor binding protein-3 and the booroola fecundity) had only one genotype, bb genotype for insulin-like growth factor binding protein-3 digested with haeiii and ++ genotype for the booroola fecundity digested with avaii enzyme, therefore they are not recommended in the selection program. the result of chi-square analysis indicated that the three egyptian sheep breeds were in hardy-weinberg equilibrium.

متن کاملPolymorphisms in Epigenetic and Meat Quality Related Genes in Fourteen Cattle Breeds and Association with Beef Quality and Carcass Traits
Improvement for carcass traits related to beef quality is the key concern in beef production. Recent reports found that epigenetics mediates the interaction of individuals with environment and nutrition. The present study was designed to analyze the genetic effect of single nucleotide polymorphisms (SNPs) in seven epigenetic-related genes (DNMT1, DNMT3a, DNMT3b, DNMT3L, Ago1, Ago2, and HDAC5) a...

Heritabilities and genetic correlations between weaning weight (WW) and average daily gain (ADG) for the Hungarian Merino, Ile de France, Charollais, German Mutton Merino, German Blackheaded, Texel, Fleisch Merino and Suffolk were studied. The selection of replacements is based on the two traits. The amount of records provided by the Hungarian Sheep Breeder’s Association and by the Hungarian Ag...
متن کاملPCR-RFLP of IGFBP-3 Gene in Some Egyptian Sheep Breeds
The present investigation was to study DNA polymorphism of insulin-like growth factor binding protein-3 (IGFBP-3) gene by PCR-RFLP in four Egyptian local sheep breeds. Genomic DNA was isolated from a total of 20 animals from four Egyptian breeds (five each) of sheep namely Rahmani, Ossimi, Awassi, and Barki. A fragment of IGFBP-3 gene, comprising of a part of exon 2, complete intron 2, exon 3, ...

Meat quality and carcass composition are the most important economic traits in sheep. Body fat and fat-tail are key factors affecting carcass quality and meat production in each breed, and mutations in sequences of the genes that control these traits can affect the animal performance and therefore the breeding value. The aim of this study was to investigate the polymorphism in some regions...
