Effect of Live Weight and Differing Economic Values on Responses to Selection for Milk Fat, Protein, Volume, and Live Weight [PDF]

open access: yesJournal of Dairy Science, 1997
Five traits of major economic importance in the New Zealand dairy industry are milk volume, milk fat, milk protein, live weight, and survival. This study evaluated the impact of live weight as a trait in the selection objectives for the New Zealand dairy industry.

Live weight accounting for beef cow management [PDF]

open access: yes, 2022
Calculation and use of annual live weight production of a group of beef cattle, ie, net harvest of live weight from their grazing area over a year, which is a primary beef cattle business measure directly indicating income, is limited in practice because

A covariance function for feed intake, live weight and milk yield estimated using a random regression model [PDF]

open access: yes, 1999
To enable investigation of genetic variation during early lactation in heifers, multitrait covariance functions were used to describe genetic covariances among feed intake, live weight, and milk yield during the first 15 wk of lactation (n = 628). Random

Multi-trait covariance functions to estimate genetic correlations between milk yield, dry matter intake and live weight during lactation [PDF]

open access: yes, 1999
Energy balance is a function of dry-matter intake (DMI), live weight and milk yield over a certain time period. To investigate potential strategies to use genetic selection for the improvement of the negative energy balance, genetic co-variances were ...

Can live weight be used as a proxy for enteric methane emissions from pasture-fed sheep? [PDF]

open access: yesSci Rep, 2015
To test the hypothesis that sheep live weight (LW) could be used to improve enteric methane (CH4) emission calculations, mature ewes of 4 different breeds representative of the UK sheep industry were studied: Welsh Mountain, Scottish Blackface, Welsh ...

Live animal measurements, carcass composition and plasma hormone and metabolite concentrations in male progeny of sires differing in genetic merit for beef production [PDF]

open access: yes, 2009
peer-reviewedIn genetic improvement programmes for beef cattle, the effect of selecting for a given trait or index on other economically important traits, or their predictors, must be quantified to ensure no deleterious consequential effects go unnoticed.

The estimation of live weight from body measurements in Yankasa sheep

open access: yesCzech Journal of Animal Science, 2006
Live body measurements of weight, height, length, girth, stifle- and hip-width and a measure of muscularity (ratio of stifle to hip width) were monitored on 258 Yankasa sheep stratified into age categories of 1 to over 3 years determined mostly from ...

Effects of Transport on Live Weight and Behavior of Lambs

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The study has monitored the effects of transport stress on some biochemical indicators of stress and behavior lambs at time of slaughter. The research was carried out in the cold season, on a number of 120 lambs, transported for 6h-16h, to be slaughtered.
