“…Clostridium bacteria are sensitive to low water activity, therefore their performance is higher in conditions of low DM. Machado et al (2012), studying the quality of forage sorghum hybrids silage, noted good fermentation in the ensiled mass, with average values of acetic acid between 0.53 and 1.45 %, similar to those observed in this study, and butyric acid between 0.00 and 0.06 %, lower than those observed in this study.…”

Sorghum stands out among other plants recommended for ensiling due to its forage composition, its resistance to drought, and its planting range. New cultivars of grain and sweet sorghum that can be used for silage production are available, but there is little information regarding their ensiling characteristics. The aim of this study was to evaluate the fermentation characteristics at the ensiling of different purpose sorghum cultivars, at two crop periods. The trial was carried out at the Plant Production Department of the Federal Institute of Education, Science and Technology of Rondônia, Colorado do Oeste campus, Rondônia, Brazil, and chemical analyses were performed at the Laboratory of Animal Nutrition, at the Federal University of Mato Grosso, Cuiabá campus, Mato Grosso, Brazil. The experimental design used was a randomized block, in split-plot design, with four replicates. The plot treatments consisted of six sorghum cultivars grown for different purposes (grain sorghum: BRS 308 and BRS 310; forage sorghum: BR 655 and BRS 610; sweet sorghum: BRS 506 and CMSXS 647). Split-plot treatments consisted of two cropping seasons (first crop and second crop). The grain sorghum cultivar BRS 310 was the only one that had suitable dry matter content for ensiling; however, it was also the only one that did not show ideal water soluble carbohydrate content for ensiling. Nevertheless, all treatments presented pH below than 4.2 and ammonia nitrogen lower than 12% of total N, which indicates that the fermentation inside the silo had proceeded well. For sweet sorghum cultivars, higher ethanol and butyric acid content were observed for the first crop than for the second crop. All evaluated sorghum cultivars can be used for silage production, but the use of sweet sorghum is recommended at the second crop. Key words: Alcoholic fermentation. Fermentability coefficient.

“…Due to the different concentrations of WSC for the cultivars variation was observed in the fermentation process (Table 3). Evaluating same cultivars 'BRS 610' and 'BRS 655' FILYA & KARABULUT (2004) and FRANÇA et al (2011) found values close, but lower than those found by MACHADO et al (2012). In general the average observed among cultivars under study, 45.92g kg -1 of LA, are considered satisfactory according to McDONALD et al (1991), to ensure appropriate fermentation.…”

This study aimed to assess the fermentation profile, losses and chemical composition of the silages of five sorghum cultivars. A completely randomized design with five replicates was used. The experimental treatments were represented by five sorghum cultivars (Sorghum bicolor (L). Moench): 'BRS Ponta Negra' , 'BRS 610', 'BRS 655', 'BRS 800' and 'BRS 810'. There was variation (P<0.05) RESUMO Objetivou-se com este estudo avaliar o perfil fermentativo, perdas e a composição bromatológica de silagens de cinco cultivares de sorgo. Foi utilizado um delineamento experimental inteiramente casualizado com cinco repetições. Os tratamentos experimentais foram representados por cinco cultivares de sorgo (Sorghum bicolor (L). Moench): 'BRS Ponta Negra', 'BRS 610', 'BRS 655', 'BRS 800' e 'BRS 810'. Houve variação (P<0,05)

“…With respect to CP, it is observed in Table 4 the lower value was obtained sorghum silage if different (p < 0.05) from other silages, and these values were higher than those found by Machado et al (2012), which was 5.92 at the dough stage, probably related to the greater proportion of panicles in the DM, once the hybrid used was the grain hybrid. It is noteworthy that in all forage systems, silages showed CP levels above 70 g kg -1 DM, the minimum for no impairment of ruminal microbial growth and consequently to occur efficient use of the fiber of silages .…”

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...
