[Growth studies in bulls of the black-and-white dairy cattle breed at a low feeding level. 1. Growth progress and fattening performance].
In 2 experiments with a total of 108 black-and-white dairy bulls feed intake, growth performance and energy expenditure for live weight and carcass production with low feeding intensity were ascertained. The performance level varied between 600 and 650 g; 24-month-old bulls achieved a final weight of 458 and 517 kg resp. Growth and retention performance were considerably influenced by the energy concentration of the ration and by daily energy intake.
