identification of genomic regions associated with wool diameter in iranian sheep breeds

Wool production in some fat-tailed iranian sheep breeds I. some quantitative characteristics of karakul.mehraban,naeini,ghezel and bakhtiari breeds

Identification of Genomic Regions Associated with Phenotypic Variation between Dog Breeds using Selection Mapping

The extraordinary phenotypic diversity of dog breeds has been sculpted by a unique population history accompanied by selection for novel and desirable traits. Here we perform a comprehensive analysis using multiple test statistics to identify regions under selection in 509 dogs from 46 diverse breeds using a newly developed high-density genotyping array consisting of >170,000 evenly spaced SNPs...

Physical Properties of Wool of Different Breeds of Sheep

The studies on physical properties of wool of six breeds of sheep of Punjab, Jammu and Kashmir. Sixty wool samples, 10 from such of the six breeds were selected to study the physical properties of wool. The study revealed that Dorset (exotic) had maximum staple length followed by Rambuillet (exotic) had maximum staple length followed by Rambuillet (exotic), i.e. 6.03 cm and 5.74 cm respectively...

Performance of hair breeds and prolific wool breeds of sheep in southern Illinois: wool production and fleece quality.

The objective of this study was to compare weight and quality of fleeces of different F1 ewe types produced from breeds with a broad range of fleece types. Weights of 629 fleeces produced during 1988 through 1991 from F1 ewes that were daughters of Suffolk and Targhee dams and Finnsheep, Combo-6, Booroola Merino, St. Croix, and Barbados sires were recorded. Staple length was measured on the mid...

Polymorphism of some Genes Associated with Meat-Related Traits in Egyptian Sheep Breeds

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 react...

DRB1 Gene Patterns of Two Iranian Sheep Breeds

Genetic improvement programs may improve disease resistance in animal production. The best-characterized genetic control of disease resistance and immune response in animals is the one associated with the Major Histocompatibility Complex (MHC). The ovine lymphocyte antigenof DRB1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...
