In an experiment designed to test the effect of different protein and energy treatments on body mass restriction of broiler breeder pullets, carcass analyses were carried out on these birds at 3 different stages during the growing period. None of…
A total of 224 pigs were used in two experiments to study the effect of two isocaloric diets containing 16,4 or 11,7% crude-protein on rate of gain, feed conversion efficiency, carcass characteristics and carcass composition of baconers, fed ad libitum…
Merino wethers were used to study adaptation to biuret and the effect of a 3-day interruption in feeding biuret to fully adapted sheep. N-retention and urinary biuret concentration were used as criteria. When fed 7g biuret daily in addition to…
Twenty-four South African Mutton Merino ewe lambs were artificially reared in a 22-factorial experiment on 5 or 10 kg milk substitute to weaning at 25 or 30 days. From weaning until a minimum of 100 days of age and a…
