Equations for predicting the meat, fat and bone proportions in beef carcasses using the European Union carcass classification scores for conformation and fatness, and hindquarter composition were developed and their accuracy was tested using data fro

Validation of economic indexes under a controlled experimental environment, can aid in their acceptance and use as breeding tools to increase herd profitability. The objective of this study was to compare intake, growth and carcass traits in bull and

In 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 obj

This study examined the relationship of muscular and skeletal scores and ultrasound measurements in the live animal, and carcass conformation and fat scores with carcass composition and value using 336 steers, slaughtered at 2 years of age. Live anim

The objective was to determine the relationship of muscular and skeletal scores taken on the live animal and carcass conformation and fat scores with carcass composition and value. Bulls (n = 48) and heifers (n = 37) of 0.75 to 1.0 late-maturing bree

The cost of grazed grass is less than half that of grass silage (O’Kiely, 1994) and incomes from beef production are low and largely dependent on EU support schemes. Thus the income from beef production could be incresed by reducing feed costs thro

Increasingly the market demand is for carcasses of better conformation which is reflected in carcass prices. Therefore the breeding policy for suckler herds must reflect market requirements. This study examined the usefulness of ultrasonic scanning a

The increased retention of within herd replacements will inevitably result in an increasing proportion of continental breed (mainly Charolais) in the suckler cow herd. Due to the high costs of silage production, winter feeding of suckler cows is expe

The costs associated with indoor finishing, i.e. ensiling grass, storage of silage and slurry, providing animal accommodation and disposal of slurry are substantial. Thus, where possible animals approaching slaughter should be finished at pasture rat

A feature of EU beef production following the introduction of milk quotas in 1984 has been the decrease in calf supplies from the dairy herd and increased supplies from the suckler herd. As a result, suckler cows have increased from 20% of the cow he
