Abstract: RESUMO -As silagens de 13 cultivares de girassol (Helianthus annuus L.), produzidas com plantas contendo mais de 90% de grãos maduros, foram avaliadas quanto às características químicas e à digestibilidade in vitro da matéria seca (DIVMS). Os dados foram analisados segundo delineamento experimental inteiramente ao acaso e a comparação das médias, feita pelo teste SNK. O menor teor de matéria seca (19,8%) foi obtido para o híbrido M737 e os maiores, para os híbridos Contiflor 7 (31,2%) e Cargill 11 (32,2%). Os … Show more

“…The DM content observed in the silage is appropriate, since it is above 250 g/kg, the lower limit set to obtain suitable fermentation with reduced losses by the effluents production (McDonald et al, 1991). It is also within the range of 30 to 35% recommended by Tomich et al (2004). Similarly, the content of CP obtained in summer, spring and autumn are within the range of values usually observed in corn silage, ranging from 60 to 90 g/kg (Melo et al, 1999).…”

“…Attention should be paid to the speed at which pH declines, since there is a rapid initial acidification, which is the key to control the growth of enterobacteria and Clostridium, which may grow to an inhibitory concentration of non-dissociated acids (Pahlow, Muck, & Driehuis, 2003) and or maintain the pH within the optimal range, which is 3.8 to 4.2 (Tomich et al, 2004). In this sense, silages of Urochloa brizantha cultivars in monocropping system did not show pH within the optimal range.…”

“…Além disso, o conteúdo de proteína da silagem de girassol é superior ao das silagens de milho e sorgo. Tomich et al (2004) avaliaram 13 cultivares de girassol e revelaram que, em média, as silagens apresentam características de silagens bem conservadas, sem perdas significativas de matéria seca e de energia e apenas pequenas alterações da fração proteica da forragem conservada em relação à forragem verde.…”
