An experiment was carried out to assess the performance of steers on Brachiaria brizantha and Cynodon dactylon cv. Coast cross pastures by the continuous stocking method with a variable stocking rate. A completely randomized experimental design was used with two pastures representing the treatments, each containing 10 replicates. The results of t-tests demonstrated that the steers grazed for less time (7:19 h) on the B. brizantha grass pasture than the on Coast-cross grass pasture (8:13 h). There was no difference in rumination time from 6:46 and 6:89 h for the B. brizantha and Coast-cross pastures, respectively. There was a significant difference for the values regarding the time that the steers remained idle, and the animals were more frequently idle on... |

This study measured the kinetic parameters of the ruminal degradation of the silage of Brachiaria brizantha cv. Marandu. The experiment had a completely randomized design with five treatments and five repetitions; the treatments featured the inclusión of natural brewer’s grain to Marandu grass silage at levels of 0, 10, 20, 30 and 40%. The regression equation for the degradability of the soluble Fraction A of dry matter showed a linearly increasing pattern (P<0.05) with an addition of 0.19% for each 1% of brewer’s grain included. The percentage of insoluble potentially degradable fraction (B) of dry matter was reduced linearly (P<0.05). The ruminal degradation rate in the dry matter (c), expressed as % h-1, increased linearly... |
