Consumo de materia verde en terneros al destete con gramínea de corte y polyscias guilfoley.

Abstract

The present research was carried out with the objective of estimating green matter intake in calves at weaning with cut grass and Polyscias guilfoley, for which three treatments were evaluated: T1 (Fresh grass), T2 (Naturally dehydrated grass at 24 hours) and T3 (Naturally dehydrated grass at 24 hours) arranged in a Complete Randomized Design. The variables evaluated were: total green matter consumption, daily green matter consumption and percentage green matter consumption. The results established that the total green matter consumption of Cuba 22 grass (Pennisetum sp) at three levels of dehydration and Pestaña (Polyscias guilfoley), was better with T1 (fresh grass) and T2 (naturally dehydrated grass at 24 hours) with 1, 00 and 1.06 kg per day, it is likely that natural dehydration of Cuba 22 grass plus Polyscias guilfoley for 24 hours is a viable practice that maintains optimal levels of intake in relation to calf live weight. As for the percentage consumption of green matter of Cuba 22 grass (Pennisetum sp) at three levels of dehydration and Pestaña (Polyscias guilfoley), T1 (fresh grass) and T2 (naturally dehydrated grass at 24 hours) with 10.12 and 10.49 %, respectively, were superior.
