ABSTRACT – The effects of different concentrate levels on the ingestive behavior were studied with five rumen and abomasum fistulated Holstein bull calves, with average initial age of 10.8±0.8 months and average 233.4±26.1 kg BW. The animals were housed in individual stalls and ad libitum fed diets containing 30, 45, 60, 75 and 90% of concentrate, on DM basis. The diets contained, approximately, 16% CP were formulated for body weight gain of 1.0 kg/day and constituted of soybean meal corn […]
