Abstract
an extensive rearing system, immediately after birth, the calf follows the mother to graze on pasture. This condition certainly affects nutrient digestibility because the digestive system is not yet fully developed. The study aims to reveal nutrient digestibility of preweaning calves fed flushing diets under extensive grazing. The study used a completely randomized factorial design with two factors and five replicates. The first factor is gender and the second one is diet treatment. The total number of calves used in this study was 30, consisting of 15 males and 15 female preweaning Pasundan calves. The dietary treatment included: (1) calves are allowed to graze without feeding flushing diet, (2) calves are allowed to graze and fed a flushing diet without urea-impregnated zeolite (flushing-1), (3) calves are allowed to graze and fed a flushing diets with urea-impregnated zeolite inclusion (flushing-2). The measured variables consisted of feed intake and apparent digestibility of nutrients. The collected data were analyzed by a general linear model univariate analysis. The results showed that compared to the control diet, supplementation of flushing diets increased (P<0.05) dry matter digestibility up to 29.01% (53.89 ± 4.85% in grazing calves vs. 80.94 ± 1.65% in flushing-1 calves or 82.90 ± 1.47% in flushing-2 calves), crude protein digestibility up to 5.71% (86.17 ± 2.91% in grazing calves vs. 90.61 ± 1.65% in flushing-1 calves or 91.88 ± 0.79% in flushing-2 calves), ether extract digestibility up to 12.12% (80.06 ± 7.39% in grazing calves vs. 92.18 ± 1.57% in flushing-1 calves or 90.09 ± 1.20% in flushing-2 calves), neutral detergent fiber up to 28.81% (54.58 ± 4.01% in grazing calves vs. 81.13 ± 3.41% in flushing-1 calves or 83.39 ± 1.75% in flushing-2 calves), acid detergent fiber by up to 24.27% (54.23 ± 4.69% in grazing calves vs. 72.41 ± 6.78% in flushing-1 calves or 78.50 ± 3.49% in flushing-2 calves), and cellulose by up to 22.79% (61.01 ± 5.15% in grazing calves vs. 82.03 ± 6.04% in flushing-1 calves or 83.80 ± 1.92% in flushing-2 calves). In conclusion, supplementing flushing diet to preweaning Pasundan calves under extensive grazing improved most nutrient digestibility parameters (dry matter, crude protein, ether extract, and fiber).
