“…Based on these results, it can be suggested that the presence of sorghum in intercropping systems raised the TDN. A similar finding was observed by Leonel et al (2009), who reported that the average TDN content of silages in intercropping systems was higher than those achieved in the silages of grasses in monocrop.…”

ABSTRACT.Recently it has emerged a technique for silage production of intercropping systems of annual crop with forage through crop-livestock integration, aiming to reduce the deficit forage in the offseason. The study was conducted to evaluate the fermentation characteristics and nutritional value of silage of sorghum and Urochloa brizantha cultivars monocropped or intercropped in different planting systems. The experiment was a randomized block design, with three replications, in a 3x2+4 factorial arrangement, with three cultivars of Urochloa brizantha (Marandu; Xaraes and Piata) intercropped with grain sorghum in two planting systems (row and between rows) and four monocrops (Sorghum, Marandu palisadegrass, Xaraes palisadegrass and Piatã palisadegrass). The planting system of intercropping systems did not interfere with fermentation characteristics and chemical composition of silages. The same was found for Urochloa cultivars. Silages from intercropping sorghum with Urochloa brizantha cultivars had lower pH values, buffering capacity, acetic and butyric acids and higher values of lactic acid, besides showed superior quality, as for the parameters dry matter, ether extract and total digestible nutrient than silages from grasses produced in monocropping system. Therefore, silages of intercropping systems ensure fermentation and nutritional quality, providing interesting supplementary bulky options to be used in the offseason for feeding animals.Keywords: conservation, digestibility, fermentation, crop-livestock integration.Qualidade de silagem de sorgo e cultivares de Urochloa brizantha em monocultivo e consorciado em diferentes sistemas de semeadura RESUMO. Surgiu recentemente a técnica de produção de silagem de sistemas consorciados de cultura anual e forrageira tropical, na integração lavoura-pecuária, com intuito de minimizar déficit de forragens na entressafra. Sendo assim, objetivou-se avaliar as características fermentativas e valor nutritivo da silagem de sorgo e cultivares de Urochloa brizantha em monocultivo e consorciado em diferentes sistemas de semeadura. O delineamento experimental utilizado foi o de bloco ao acaso, com três repetições, em esquema fatorial 3x2+4, sendo três cultivares de Urochloa brizantha (Marandu, Xaraés e Piatã), consorciadas com sorgo granífero em dois sistemas de semeadura (linha e entrelinha) e quatro monocultivos (Sorgo, Marandu, Xaraés e Piatã). A forma de semeadura dos sistemas consorciados não interferiu nas características fermentativas e químico-bromatológicas das silagens. O mesmo foi obtido para cultivares de Urochloa brizantha. As silagens do consórcio do sorgo com cultivares de Urochloa brizantha apresentaram menores valores de pH, capacidade tampão, N-NH 3 , ácido acético e butírico e maior ácido lático, além da qualidade superior, quanto aos parâmetros matéria seca, extrato etéreo e nutrientes digestíveis totais. Portanto, silagens dos sistemas consorciados garantem adequado processo fermentativo e qualidade nutricional, constituindo interessantes opções de volum...

“…Low concentrations of lignin is considered relevant to improving the nutritional value of forage and increased consumption of silage by animals, because the lignin is associated with indigestible food, however, more important than its content is its structural arrangement in the cell wall forage (JUNG;DEETZ, 1993). However, there have been approached the lignin content in tropical grasses as depressive fraction of food (LEONEL et al, 2009), therefore, low levels of lignin allow better use of the fiber by microorganisms in the rumen (RIBEIRO et al, 2008). Guimarães Junior (2005a) evaluating the fibrous fractions of silages of three pearl millet genotypes, observed lignin concentration of 4.01, 3.34 and 4.31% for the CMS-1; BRS-1501 and BN-2 genotypes, respectively, after the fermentation period of 56 days.…”

The millet has being prominent in recent years, especially with the arrival of early genotypes with high nutritional value and productive potential, coming from breeding. As these genotypes are new, little information exists about them. Thus, it is important to obtain technical information, supported by scientific studies about the behavior of these materials considering the nutritional value and harvest for silage production. The objective of this research was to evaluate the silage quality of pearl millet genotypes grown in different cuts age. The experiment was carried out on the campus of the Agronomy, of the Rio Verde University. The experimental design was randomized blocks with four replications in a 5 x 3 factorial, with five genotypes of millet: ARD 500, ADR 7010, LAB 0730, LAB 0731 and LAB 0732 and three cuts ages: 57, 65 and 73 days after sowing (DAS). The results showed that silages produced by millet, regardless of genotype, could be considered of nutritional value. Since this is a precocious material the best age that provided the best quality of these silages was when the materials were harvested at 57 DAS. Key words: Soluble carbohydrates, fibrous fraction, pH ResumoO milheto vem ganhando destaque nos últimos anos, principalmente com a chegada de genótipos precoces e de alto valor nutritivo e potencial produtivo, oriundos do melhoramento genético. Por se tratarem de materiais novos, existem poucas informações sobre esses genótipos. Nesse sentido, é importante obter informações técnicas, apoiadas em estudos científicos, sobre o comportamento desses materiais em relação ao valor nutritivo e época de colheita para a produção de silagens. Diante disso, objetivou-se avaliar a qualidade de silagem de genótipos de milheto produzidas em diferentes idades de cortes. O experimento foi conduzido no Campus da Faculdade de Agronomia da Universidade de Rio Verde. O delineamento experimental utilizado foi de blocos ao acaso, com quatro repetições, em esquema fatorial 5 x 3, sendo, cinco cultivares de milheto: ARD 500, ADR 7010, LAB 0730, LAB 0731 e LAB 0732 e três idades de cortes: 57, 65 e 73 dias após a semeadura (DAS). Os resultados mostraram que as silagens produzidas por milheto, independente do genótipo, podem ser consideradas de boa qualidade. Por se tratar de materiais precoces a melhor idade que proporcionou melhor qualidade da silagem desses materiais, foi quando os materiais foram colhidos aos 57 DAS.

“…The addition of 15% of millet meal increased by 11% the TDN content when compared with no application of this additive on silage fermentation. In a study on qualitative and nutritional characteristics of Brachiaria grass silage, Leonel et al (2009) The pH of silages was not affected (P>0.05) by the interaction of cultivars and levels. There was a significant effect of cultivar (Table 2) and levels of millet meal inclusion (Figure 4b).…”

The silage quality of Brachiaria brizantha cultivars ensiled with different levels of millet meal was evaluated. The experimental design was a completely randomized with three replications in a factorial 3 x 4, with three cultivars of Brachiaria brizantha: marandu, xaraés, and piatã and four levels of millet meal 0, 5, 10, and 15%. The addition of millet meal improved the quality of B. brizantha silage. The inclusion of the additive at 15% provided the best nutritional values. The piatã silage had the lowest contents of neutral detergent fiber, acid detergent fiber, and lignin and the highest content of total digestible nutrients, being a better quality silage as compared to those of xaraés and marandu grasses.
