Abstract: -Two sugarcane varieties (IAC86-2480 and IAC91-2195) combined or not with soybean hulls (SH), partially replacing corn in concentrate, were included in the diet of crossbred dairy cows to evaluate the effects on feed intake, milk production, milk composition and rumen parameters of crossbred cows. The sugarcane varieties (IAC86-2480 and IAC91-2195) and concentrate compositions (with and without SH) were analyzed in a 2 × 2 factorial arrangement. Treatments were assigned to blocks by lactation period to evaluat… Show more

“…As expected, MS and SC samples presented greater NDS concentrations, which are closely associated with their intrinsic starch and sucrose content. Both MS and SC samples were collected at recommended ranges of DM (from 257 to 350 g/kg) and Brix (minimum of 18° Brix) concentrations for high starch digestibility and sucrose concentrations respectively (Jensen, Weisbjerg, Nørgaard, & Hvelplund, ; Lima et al., ).…”

“…Considering the low pdNDF and high content of sucrose in fresh sugarcane, diets with this forage given to dairy cows should be formulated using other sources of pdNDF with relatively lower starch concentrations (e.g., whole cottonseed, citrus pulp, or soybean hulls). However, data about the use of by-products with high pdNDF concentration in high-concentrate, sugarcane-based diets are scarce in the literature (Lima et al, 2014). The UFA have little influence on rumen MPS, and changes in the efficiency of microbial N synthesis as a consequence of fat supplementation are mainly associated with the decrease in rumen protozoa populations or RFOM (Doreau and Ferlay, 1995).…”
