Abstract

The present experiment has the objective to compare four levels of soyhulls inclusions in the starter rations for early weaned dairy calves, through the avaliation of  weight gain, feed intake and feed conversion. Thirty six  Holstein (24) and Jersey (12) dairy calves were used, distributed in four treatments with different levels of soyhulls (0, 15, 30 and 45%) added in calf starter containing ground corn, soybean meal, whey powder plus minerals and vitamins. The experiment was carried out for 16 weeks, considering eight weeks for liquid feeding period and eight weeks post-weaning. The calves received 4.0 kg of whole milk fed twice daily. Calf starter and water was offered ad libitum. Post-weaning the calves were feed with calf starter, alfalfa hay and water until 16th week. liveweight, daily gain, milk intake, starter intake, hay intake and feed conversion were registered. Starter and hay offered and refused was weight daily. No significant difference were observed for any variables analyzed (P>0.05). It was concluded that soyhulls can included until 45% in the calf starter ration for calves weaned with eight weeks.
