- Abstract
An experiment was carried out with the objective of evaluating the productive response and digestibility of dry matter in bulls grazing on African star grass (Cynodon plectostachyus L.), supplemented with sugar cane ensilage (SCE) (Saccharum spp.) and a fibrolytic enzymatic complex. Forty (40) Bos taurusxBos indicus young beef bulls were used (initial weight 375±29 kg) during a period of 125 days. They were fed individually with restricted access to the ensilage (16 % RP), and organized in a Completely Random Design with four treatments and ten repetitions in the following way: 1) Control (TP), 2) TP+SCE, 3) TP++CE+15g Fibrozyme animal-1 day-1, 4) TP+SCE+30g Fibrozyme animal-1 day-1. The animal load was eight animals ha-1 in the treatments with SCE and 3.3 in the control. The daily weight gain of the young beef bulls improved (P<0.05) with the use of the enzyme: 1) 395.17b, 2) 457.60ab, 3) 703.76a, 4) 621.21ab g day-1, which was associated with a higher consumption: 1) 11.36b, 2)14.68ab, 3) 17.09a, 4) 15.25ab kg animal-1 day-1 and digestibility of the dry matter (P<0.05), compared to the control group: 1) 63.21b, 2) 63.67b, 3) 68.58a, 4) 66.61ab (%). The use of fibrolytic enzymes in sugar cane ensilage increased the digestibility, improved the consumption, weight gain, and food conversion in young beef bulls grazing on African star grass.
