AbstractFull Text

Data on 6054 Sirohi kids of 112 sires born during 2004 to 2016 in farmers' flocks under All India Coordinated Research Project on Goat Improvement, Vallabhnagar (Udaipur) were utilized to estimate the average daily gains (ADG) at different growth stages. The overall least-squares means of ADG for...

Aim: The aim of this study was to estimate the heritability, genetic and phenotypic correlations, and the genetic trends for pre-weaning growth traits including the birth weight (BWT), weaning weight (WWT), pre-weaning daily gain (PWDG), and weaning age (WA) in Awassi lambs. Materials and Methods:...

Abstract

The preweaning calf survival (SW) is one of the main economic bottlenecks of beef cattle rearing systems, however there is still few quantitative studies approaching this issue. Being a binary trait, genetic parameters for SW can be estimated considering continuous or categorical data under...

The objective of this work was to study "days for a specific weight" traits in Nelore breeding programs comparing them with traditional traits such as average daily weight gain. Thus, this study aimed to estimate genetic parameters for days to reach 180 kg (D180), days to reach 300 kg (D300),...

Abstract

Most breeding companies evaluate economically important traits in males and females as a single trait, assuming genetic correlation of 1 between phenotypes measured in both sexes. This assumption may not be true because genes may be differently expressed in males and females. We estimated genetic...

AbstractFull Text

This study was carried out to investigate variance components, direct, maternal genetic parameters, estimated breeding values and factors affecting pre-weaning growth criteria of Romney sheep. Data were collected over the period from 2006 to 2012 with records of 4989 lambs descended from 76 rams...

AbstractFull Text

The aim of this study was to evaluate non-genetic factors and genetic parameters of the growth traits in Sumba Ongole (SO) cattle. The growth traits were consisted of birth weight (BW), weaning weight (WW), yearling weight (YW), average daily gain of pre-weaning (ADG1) and post-weaning (ADG2). Data ...

A total 1905 first farrowing records of Landrace × Desi individual pigs were analyzed to study effect of various non genetic factors on different pre-weaning individual body weights and to estimate of breeding values of boars for weaning weight. The average least squares means for BW, 15dW, 28dW,...
