“…Among the available or recommended crops for ensiling, grasses of the genus Brachiaria have attracted interest and have been widely used with positive results (COSTA et al, 2011a;EPIFANIO et al, 2014;PERIM et al, 2014). In addition, interest in producing silage with this species partially results from advances in ensiling techniques and the emergence of specific harvesters for small or medium-sized forages.…”

ABSTRACT:With the arrival of new early genotypes and high nutritive value and productive potential, millet has been gaining prominence in recent years for the production of silage, and it promises lower costs of production. Thus, the consortium of millet with tropical forages can increase the production of silage, providing more food to be used in the offseason, where there is low availability of forage. The objective of this study was to evaluate the dry mass production, fermentative characteristics and chemical-bromatological of pearl millet silage and Paiaguas palisadegrass in monocropping and intercropping in different forage systems in the second cropping season. The experimental design consisted of randomized blocks with four replicates. The treatments consisted of silage of the following forage systems: monocropped pearl millet, monocropped Paiaguas palisadegrass, pearl millet intercropped in rows with Paiaguas palisadegrass, pearl millet intercropped inter-row with Paiaguas palisadegrass, and pearl millet oversown and intercropped with Paiaguas palisadegrass (totaling 20 experimental plots). The consortium of pearl millet with Paiaguas palisadegrass contributed to raise the dry matter contents of the silages, except in the system using the overgrowth. Pearl millet silages monocropped and intercropped with Paiaguas palisadegrass presented reductions in pH and ammoniacal nitrogen values as well as favor lactic fermentation. Pearl millet monocropped and intercropped silage exhibited better fermentative and bromatological characteristics than silage obtained from monocropped Paiaguas palisadegrass. Therefore, creating silage from intercropped forages provides an interesting supplemental roughage option that can be used during the offseason for animal feeding.

“…For all the brans, the level of 15% was the most effective in increasing the fraction A. This is an outstanding result because this soluble fraction has rapid ruminal degradation owed the higher content of CP in the brans (EPIFANIO et al, 2014), improving thus the degradation rate. According to Russell et al (1992), non-protein nitrogen sources are essential for the proper functioning of the rumen, since ruminal microorganisms fermenting structural carbohydrates use ammonia as a nitrogen source.…”

“…These results are assigned to the lowest content of CP of Piata palisadegrass in relation to the brans thus (EPIFANIO et al, 2014), higher fractions B3 are achieved in the control, with a slower degradation.…”

ABSTRACT. This study aimed to determine the protein and carbohydrate fractionation of Piata palisadegrass silage of brans from biodiesel industry. The experiment was developed in the Federal Institute of Goiás State, Campus Rio Verde, with a completely randomized experimental design, four replications, in a 4 x 4 factorial scheme, with four oleaginous brans (cotton, sunflower, soybean and canola) and four levels of inclusion (0, 5, 10 and 15%). The results showed that brans from biodiesel industry are good sources of additives for ensiling the Piata palisadegrass, by considerably improving fractions of proteins and carbohydrates. However, the soybean meal proved to be more efficient by having higher fractions of proteins and carbohydrates A+B1 and lower fractions C, compared with other additives. It is recommended the addition of 15% of brans for providing better nutritional value of silage.Keywords: additive, Brachiaria brizantha, CNCPS, silage.Fracionamento de proteínas e carboidratos da silagem de capim-piatã com farelos da indústria do biodiesel RESUMO. Objetivou-se determinar o fracionamento de proteínas e carboidratos da silagem de capimpiatã com farelos da indústria de biodiesel. O experimento foi conduzido no Instituto Federal Goiano, Campus Rio Verde. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições e em esquema fatorial 4 x 4, sendo quatro farelos oleaginosos (algodão, girassol, soja e canola) e quatros níveis de adição (0, 5, 10 e 15%). Os resultados demonstraram que os farelos da indústria do biodiesel constituem em boas fontes de aditivos para a ensilagem do capim-piatã, por trazer melhorias consideráveis nas frações de proteínas e carboidratos. No entanto, o farelo de soja mostrou ser mais eficiente, para melhorar a qualidade da silagem, por apresentar maiores frações proteícas e carboidratos A+B1 e menores frações C, quando comparado com os outros aditivos. Com relação aos níveis, recomenda-se a adição de 15% dos farelos, por proporcionar melhor valor nutritivo da silagem.Palavras-chave: aditivo, Brachiaria brizantha, CNCPS, ensilagem.

“…Among the new alternatives, Brachiaria brizantha cv. BRS Piatã stands out, due to its high growth rate, good regrowth and high availability of leaves for grazing (Epifanio et al, 2014) However, there is little research about its mineral nutrition.…”

A B S T R A C TThis study aimed to evaluate the production and mineral nutrition of Piatã grass as a function of nitrogen and potassium fertilization in Oxisol collected in the Cerrado. The experiment was carried out in a greenhouse, the experimental design was completely randomized, in a 5 x 5 factorial scheme, corresponding to five nitrogen doses (0, 100, 200, 300 and 400 mg dm -3 of N) and five potassium doses (0, 90, 180, 270 and 360 mg dm -3 of K 2 O), with four replicates. Three cuts of the shoots were performed every 30 days. Chlorophyll index, dry mass of shoots and roots, and nitrogen and potassium contents in the leaves were evaluated. The dry mass of shoots showed interaction between nitrogen and potassium in the three cuts; in the second and third cuts, it had maximum production at the nitrogen and potassium doses of 254 and 158 mg dm -3 , in the second, and 250 and 306 mg dm -3 in the third, respectively. The nitrogen and potassium contents are influenced as a function of nitrogen and potassium fertilization isolated by factor. The nitrogen and potassium ratio in the Piatã grass crop was around 1:1.Nitrogênio e potássio no cultivo do capim-piatã em solo do Cerrado brasileiro R E S U M O Objetivou-se avaliar a produção e a nutrição mineral do capim piatã em função da adubação nitrogenada e potássica em Latossolo Vermelho coletado no Cerrado.
