Abstract
The study aimed at assessing the effects on growth performance and slaughter traits of two type of solid feeds (Maize grain vs. Mix) administrated to veal calves in amounts exceeding the minimum recommended by the welfare legislation. Fifty Polish Friesian calves, housed in 5 group pens per each experimental treatment, were fed the same milk replacer diet twice a day. After milk distribution a growing amount of solid feed was distributed through the fattening period. The type of solid feed did not affect calves final body weight and average daily gain although intake of solid feed was higher i calves fed the Mix diet. Carcass weight and dressing percentage were no significantly affected by the two diets. Despite the higher haemoglobin level resulted with the Mix diet, no relevant differences between the two feeding treatments were observed regarding carcass colour parameters that were suitable for the meat market.
