Study on the effect of feed space allowance on feeding behaviour in eighteen months of age heifers

Iulian Tripon

Abstract


The aim of this paper was to measure the main aspects that characterize the feeding behaviour of eighteen months old heifers using three different feeding space allowances (0.4, 0.6 and 0.84 m feeding space per heifer). During the experiments the following feeding behaviour aspects were determined: number of feeding periods, the length of one feeding period and the total length of feeding periods. When a feeding space of 0.6 m per heifer was used the total length of feeding periods in 24 hours had a value of 641 minutes, significantly bigger (p<0.05) than when feeding space was 0.4 or 0.84 m per heifer (543 and 453 minutes). There were significant differences (p<0.05) for total time spent feeding by calves between the second experimental variant (0.6 m feeding space per heifer) and the first (0.4 m feeding space per heifer) and the third experimental variant (0.84 m feeding space per heifer) during the afternoon and during the night.
