Resumo
The objective of the experiment was to avaluate the
carcass characteristics of cull cows, feedlot finished receiving
diets without or with sodic monensin (200 mg/animal/day).
The diet contained 12.5% of crude protein and 2.99 Mcal
of digestible energy/kg of dry matter, composed of 48% of
roughage (corn silage) and 52% of concentrate. Cows with
monensin in the diet presented lower weight of hot (262.3
vs 289.8 kg) and cold carcass (255.4 vs 282.6 kg), hot (52.5
vs 54.9 %) and cold carcass dressing (51.1 vs 53.5%), and
subcutaneous fat thickness (4.5 vs 6.6 mm) in relation to the
cows without monensin. Carcasses of worse conformation
were observed for the animals with monensin, reaching 8.9
points (close to regular plus) against 10.1 points (above good
minus). For cows fed with monensin the sawcut showed 9,9%
less absolute weight and, the amount of fat in the carcass
was reduced by 20.9%. Including monensin in the diet
reduced carcass weight, dressing, subcutaneous fat thickness,
conformation, sawcut and fat of the carcass of cull cows.
