The experiment was conducted at the University of Rio Verde. The experiment was performed as a randomized 3 × 3 factorial in complete block design with three replications and repeated measures in the time. Three Brachiaria brizantha cultivars (Marandu palisadegrass, Xaraes palisadegrass, and Piata palisadegrass), were tested at three cutting intensities (10, 20, and 30 cm sward height). The evaluations were conducted on the same plots throughout one year and during all four seasons (autumn, winter, spring, and summer). The results showed that the Piata palisadegrass had the best chemical composition compared to the Marandu palisadegrass and Xaraes palisadegrass. The management of Brachiaria brizantha cultivars at the lowest residual height (10 cm) affected the nutritional value of these feed grasses. Seasonality also influenced the nutritional value of these forages.展开更多

This experiment was conducted at the Goiano Federal Institute on the Rio Verde campus in Goiás State, Brazil. The experimental design was entirely random with four replications in a 4 × 5 factorial scheme that included four energetic brans (millet, maize, sorghum and wheat) and five levels (0%, 8%, 16%, 24% and 32%). The energetic brans can be considered as a good source of additives for Piata palisadegrass ensiling, which improves the qualitative and nutritional fermentative characteristics of the silage. The maize and wheat brans were the most efficient for improving the fermentative characteristics of the silage. However, millet bran was the most efficient for improving the bromatological characteristics. In addition, the wheat bran had the greatest influence on the final production cost and the sorghum and millet brans were the most economically feasible. Overall, the addition of 24% bran is recommended due to its beneficial impact on silage quality and the average final production cost of the silage.展开更多

The experiment was conducted at the Federal Institute of Goiás, Rio Verde Campus, using a randomized complete block experimental design, with four replications. The treatments consisted of the forages: Brachiaria brizantha cv. Marandu;Brachiaria brizantha cv. Xaraes;Brachiaria brizantha cv. Piata;Brachiaria brizantha cv. MG-4;Brachiaria decumbens and Brachiaria ruziziensis, intercropped in oversown corn for implantation of integrated crop-livestock system. The results showed that intercropping corn with Brachiaria grasses favors the production of high-quality forage in the offseason, and the cultivars of Brachiaria brizantha and Brachiaria decumbens showed higher dry matter production. And cultivars of Brachiaria brizantha (Marandu palisadegrass, Xaraes palisadegrass and Piata palisadegrass) are the most suitable for presenting food of better quality, compared with Brachiaria brizantha cv. MG-4, Brachiaria decumbens and Brachiaria ruziziensis.展开更多
