Genotype by Environment Interaction for Milk Production Traits in Guernsey Cattle
نویسندگان
چکیده
Current methods for routine international evaluations are based on pre-processed information. This puts several restrictions on the method of analysis that can be used. For example, comparisons need to be made on genetic evaluation unit bases. Neighboring countries with similar production environments cannot be treated as genetically identical traits, and environmental variation within country cannot be utilized. Also, the genetic correlation between countries does not only depend on genotype by interaction, but on differences between national evaluation systems as well.

Association of Prolactin Gene Variants with Milk Production Traits in Russian Red Pied Cattle
A total of 125 Russian Red Pied cows were genotyped for the prolactim-related gene. The PRL-RsaI genotypes were analysed using the Polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) method. In this breed, the frequencies of alleles were as follows; A= 0.794 and B= 0.206. The frequencies of AA, AB and BB genotypes were 0.598, 0.392 and 0.01; respectively. Results sho...

متن کاملGenetic polymorphism and association of kappa-casein gene with milk production traits among Frieswal (HF × Sahiwal) cross breed of Indian origin
The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117...
