Relationships between feed intake in subperiods and feed intake over the whole test period in young bulls



Relationships between feed intake in subperiods and feed intake over the whole test period in young bulls



Archiv fuer Tierzucht 34(3): 197-206



Three feeding trials were made with 143 Black-Pied dairy and 133 beef bulls of different genotypes which were fed individually ratios with different roughage: concentrate ratios. The daily intake rates of roughage and total feed were recorded. The feeding regime had only a minor impact on the relationships between feed intake in the subperiods and feed intake over the whole test period. The prolongation of the single subperiods did not lead to closer correlations, which were however obtained by raising the number of feeding subperiods. Hence follows that it is more efficient to increase the number of subperiods and reduce their duration than doing the opposite. In the frame of performance testing of bulls, feed intake can be readily predicted from 2- to 3-day subperiods at 6-weeks intervals.
