Animal Model Versus Conventional Methods of Sire Evaluation in Sahiwal Cattle
A total of 1,367 first lactation records of daughters of 81 sires, having 5 or more progeny were used to evaluate sires by 3 different methods viz., least squares (LS), best linear unbiased prediction (BLUP) and derivative free restricted maximum likelihood (DFREML) method. The highest and lowest overall average breeding value of sires for first lactation 305 days or less milk yield was obtaine...
متن کاملStudies on DNA fingerprinting in Murrah buffaloes using microsatellite markers
For the present study, blood samples from 35 Murrah dam-progeny pairs and semen samples of their sires were collected. All six primers successfully amplified the genomic DNA from all the animals. The mean observed heterozygosity (Ho) within the population was found to be 0.5438 and it ranged from 0.375 (CSSM43) to 0.775 (CSSM61). Average expected Levene’s and Nei’s heterozygosity (Hep) were 0.6...
متن کاملGenetic parameters for stayability in Murrah buffaloes.
In order to contribute to the breeding programmes of Asian water buffalo, the aim of this study was to analyse the influence of genetic effects in the stayability of Murrah dairy buffaloes. The stayability trait (ST) was defined as the female's ability to stay in the herd for one (ST1), two (ST2), three (ST3), four (ST4), five (ST5) or six years (ST6) after the first calving. The same trait was...
متن کاملRFLP Analysis of Beta‐Lactoglobulin Gene in Swamp and Murrah Buffaloes Using a Single Restriction Enzyme
An attempt has been made to analyze the distribution of the beta-lactoglobulin genotype in swamp buffaloes and Murrah buffaloes utilizing polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Blood samples were taken from 50 swamp buffaloes and 50 Murrah buffaloes. The DNA was extracted by the phenol-chloroform method. The PCR-RFLP was performed using beta-lactoglobulin ...
متن کاملJoint sire and cow evaluation for conformation traits using an individual animal model.
A joint sire and cow evaluation for selected type traits has been carried out for the Canadian Holstein population using an individual animal model accounting for all known relationships. Only first lactation, first classification linear records were utilized. Linear scores for final class/final score (combined), feet and legs, mammary system, and stature were analyzed. The model of analysis in...
