Performance of Holstein x Gyr dairy cows fed hydrolyzed sugarcane-based diets. Repositório Alice
CAMPOS, M. M.; Ana Luiza da Costa Cruz Borges; Carlos Giovani Pancoti; Ricardo Reis e Silva; Tainá Silvestre Moreira; LOPES, F. C. F..
Twelve multiparous 7/8 Holstein x Gyr dairy cows were fed diets based on chopped sugarcane supplied in natura (control) or after being hydrolyzed (fresh matter basis) for 24 h with 0.5%, 1% or 2% calcium oxide (CaO). The voluntary consumption and digestibility of dietary nutrients, milk production and composition, and feeding behavior of cows were evaluated. A switchback design with three periods, four treatments and three blocks was used. The linear and quadratic effects of the treatments were analyzed using orthogonal contrasts, and the effects were considered significant when P ≤ 0.05. Compared to the that in the control treatment, the Ca concentration increased by 297%, 570% and 1,083% in the diets including sugarcane hydrolyzed with 0.5%, 1%...

Rumen parameters and passage rate in cattle fed diets based on sugarcane hydrolyzed with calcium oxide. Repositório Alice
LOPES, F. C. F.; CAMPOS, M. M.; BORGES, A. L. C. C.; PANCOTI, C. G.; SILVA, R. R.; MOREIRA, T. S..
Abstract Nine non-lactating Holstein x Gyr cattle were fed with rations based on chopped sugarcane supplied in natura (control) or hydrolyzed (fresh matter basis) for 24 h with 1% or 2% calcium oxide (CaO), which corresponds to 3.1% or 6.2% CaO on a dry matter (DM) basis, respectively. Ruminal parameters (pH and ammonia N, acetate, propionate and butyrate concentrations) as well as the kinetics of fluid and particulate passage in the gastrointestinal tract from cattle were evaluated. A design using three 3 x 3 contemporaneous Latin Squares (LS) was adopted. The studies of kinetics of fluid and particulate passage were performed using the external markers cobalt-EDTA and chromium-mordanted-NDF, respectively. The ruminal parameters were analyzed according to...
