Estimation 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 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 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 کاملNon-Genetic Factors Affecting Grasscutter Production Traits. 1. Growth Traits
This study was conducted at the grasscutter section of the University of Education, Winneba, Ghana, to estimate effects of non-genetic factors on growth traits. Data consisted of records of 502 kids born from 136 does and 40 sires from 2006 to 2010. Feed intake increased (P<0.01) with increasing parity and years, whilst feed efficiency declined (P<0.01) with years. Animals consumed less (P<0.01...
