The objective of this work was to evaluate the effects of three levels of concentrate (2.0, 4.0 and 6.0 kg/cow/day) and two levels of crude protein (CP) (14 and 16% total dietary dry matter), in comparison to mineral mixture (control) on the intake, apparent digestibility, milk composition and yield and on feed efficiency and use of concentrates of cows grazing elephant grass (Pennisetum purpureum, Schum) in the rainy season. Twenty-one milking Gyr cows with average body weight of 426 kg […]

Four levels of coffee hulls (0.0, 6.25, 12.5, 18.75 and 25.0% DM) in substitution of ground corn in their concentrate ration were used to evaluate the effects on intake and apparent digestibility of diets. Twenty, unknown breed, sheeps were used in a randomized block design, with five treatments and four replicates. The animals were fed all ad libitum with isoprotein diets, 10% crude protein (CP), contained 60% of coastcross hay and 40% of concentrate in dry matter basis. Sheep were […]
