Association of IGF-I Gene Polymorphisms with Carcass Traits in Iranian Mehraban Sheep Using SSCP Analysis
Molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. The insulin like growth factor-I (IGF-I) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. The objectives of the present study were the estimate the haplotype frequencies of the IGF-I gene polymorphisms i...
متن کاملGrowth performance and carcass traits of forage-fed hair sheep wethers
The objective of the present study was to compare live animal performance and carcass characteristics of 3/4 or 7/8 Dorper (DO; n= 30), purebred Katahdin (KA; n= 20), purebred St. Croix (SC; n= 17) and purebred Suffolk (SU; n= 10) lambs born in the spring and fall of 2001. After weaning, lambs were supplemented with up to 680 g of a corn-soybean meal supplement while grazing bermudagrass pastur...
متن کاملEvaluation of Australian merino and U.S. sheep breeds for growth and carcass traits.
One hundred twenty 4-mo-old wether lambs born to Targhee ewes and sired by six rams each from Merino (Finewool, FM and Strongwool, SM), Rambouillet (Dubois, DR and Texas, TR), and Targhee (T) breeds were randomly assigned to predetermined slaughter weight groups of 43, 48, 52, and 57 kg and evaluated for growth and carcass traits. Overall mean ADG and feed conversion rate (FC, kilograms of feed...
متن کاملPolymorphisms of the Ovine Leptin Gene and its Association with Growth and Carcass Traits in Three Iranian Sheep Breeds
Leptin (LEP), the expression product of the obese gene produced primarily in the adipose tissue, is related to feed intake, growth and lipid metabolism. The aim of this study was to study the possible association between polymorphism of the LEP gene with growth and carcass traits among three Iranian sheep breeds of the Shal, Zandi and Zel varieties. A total of 180 purebred animals of the Shal, ...
