“…On the other hand the decrease in ruminal pH after the beginning of feed can be explained by the increase of carbohydrates from the rations, highly fermentable in the rumen, and the consequent production of short chain fatty acids, which, with the passage of time are absorbed by the ruminal epithelium, also explaining the reduction in pH. There was no effect (p>0.05) of the collection time for NH 3 -N content (Table 6), this behavior diverges from that reported in the literature (ZEOULA et al, 2003;DOMINGUES et al, 2010;SANTOS et al, 2012). The ammonia nitrogen values (NH 3 -N) had positive linear behavior (p <0.05) (Table 6) for diets containing different replacement levels of soybean meal by soybean cake, with the prediction equation ŷ = 29.48+ 0.03x (R 2 = 0.69).…”

“…Em contrapartida, Domingues et al (2010), observaram que a inclusão da torta de girassol em substituição ao farelo de algodão em bovinos confinados levou à queda de ingestão de matéria seca. A diferença observada por Domingues et al (2010) pode ser atribuída ao maior consumo de torta de girassol, o qual atingiu aproximadamente 2,4 kg/animal/dia de torta na dieta de maior inclusão, enquanto que no presente estudo o consumo máximo de torta de girassol foi de 609 g/animal/dia.…”

“…Sousa (2008), ao pesquisar a viabilidade econômica do uso dos subprodutos do girassol para vacas leiteiras, encontrou teores de 22,09% e 30,19% de PB; e 15,41% e 1,75% de EE para a torta e farelo, respectivamente. Domingues et al (2010) observaram valores de 23,50% PB para a torta.…”
