Continental bulls slaughtered off grass only fail to meet fat cover requirements - Research
New research at Teagasc Grange has shown that bulls slaughtered of grass only fail to achieve current fat cover requirements of meat processors.
Detailing the research, Aidan Moloney of Teagasc Grange said bulls grow faster than steers but are more aggressive and stress sensitive, which can result in a dark undesirable meat colour.
At pasture, he there is a greater risk of finishing bulls producing darker meat compared to bulls finished indoors.
Teagasc Grange researchers fed 13-month-old continental bulls of 425kg liveweight three different diets:
(a) 200 days at grass;
(b) 100 days at grass and then concentrate ad lib and grass silage indoors for 100 days; and,
(c) 200 days indoors fed grass silage and concentrate ad lib.
The pastures the bulls grazed were perennial ryegrass. When the study was completed, all bulls were slaughtered at 19 months of age. They were transported in their grazing groups directly to a commercial abattoir for slaughter.
