Genetic 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 کاملEstimation of Genetic Parameters of Lifetime Performance Traits in Murrah Buffaloes
The data on 171 Murrah buffaloes sired by 49 pertaining to lifetime performance traits were collected from history cum pedigree sheets maintained at Buffalo Research Centre (BRC), Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar over a period of 20 years from 1990 to 2009. Analysis of variance done by restricted maximum likelihood method of Harvey (1990) using mixed linear re...
متن کاملEstimation of Genetic Parameters for Production and Reproduction Traits of Holstein Cows of Mazandaran Province using Bayesian Approach
The present study was conducted to estimate the genetic and phenotypic parameters of productive and reproductive traits of Holstein cows in Mazandaran Holstein dairy cattle. To this purpose, data 39792 records of Holstein cows collected at Mahdasht Milk and Meat Company in sari during 1986 to 2015 were used. Productive traits included corrected 305 days milk records, fat and protein produ...
متن کاملEstimates of genetic parameters for fat yield in Murrah buffaloes
AIM The present study was performed to investigate the effect of genetic and non-genetic factors affecting milk fat yield and to estimate genetic parameters of monthly test day fat yields (MTDFY) and lactation 305-day fat yield (L305FY) in Murrah buffaloes. MATERIALS AND METHODS The data on total of 10381 MTDFY records comprising the first four lactations of 470 Murrah buffaloes calved from 1...
متن کاملestimation of genetic parameters for first lactation production and reproduction traits in iranian holstein cows
to estimate the genetic parameters for production and reproduction traits in holstein cows, information from 15 herds recorded by animal breeding center of iran during 1980 – 2004, were employed. estimations were made using restricted maximum likelihood method under an animal model ranging df-reml and matvec software. estimates of heritabilities for yield traits were moderate and ranged from 0....
