Abstract
Genetic Parameters for Milk Traits in Egyptian Native Cows
Highlights
Genetic Parameters for Milk Traits in Egyptian Native Cows ABSTRACT: The aim of this study is to estimate the genetic parameters and the effect of non-genetic factors for some milk traits including total milk yield (TMY), Lactation period (LP), number of services per conception (NSC), days open (DO), calving interval (CI) and dry period (DP)
The study recommends preserving the Native Egyptian dairy cattle because they represent a national wealth that must be preserved from extinction through inventorying the genetic resources, characterization and evaluation of this local breed to benefit from it in improving animal breeds of high economic value
Native cows are a national wealth that must be preserved from extinction
Summary
The genetic trends of cow breeding values were significant for all studied traits. The study recommends preserving the Native Egyptian dairy cattle because they represent a national wealth that must be preserved from extinction through inventorying the genetic resources, characterization and evaluation of this local breed to benefit from it in improving animal breeds of high economic value. The aim of the study is to address the effect of environmental conditions on milk traits and estimate the heritability, breeding value and genetic trends of Domiati (Native Egyptian dairy cattle).
