The objective of this trial was to investigate the effects of partially replacing ground corn with coffee hulls (0.0, 8.75, 17.5 and 26.25% of concentrate DM) on nutrient intake, apparent total tract digestibility, and daily weight gain of dairy heifers. Twenty-four Holstein x Zebu heifers were assigned to a randomized complete block design with four treatments and six replicates. Diets were isonitrogenous (15.5% CP) and contained 60% of Tifton-85 haylage and 40% of concentrate. Intakes of dry matter (6.75 kg/day), […]

It was studied the effects of replacing ground corn with coffee hulls on intake, apparent digestibility, and milk production and composition of lactating dairy cows. Twelve Holstein-Zebu dairy cows were blocked by days in milk and randomly assigned to three 4 x 4 Latin squares. The following levels of coffee hulls were included in the concentrate portion of the diet: 0.0, 8.75, 17.5, or 26.25% of dry mater (DM). Diets were formulated to be isonitrogenous (14% CP) and contained a […]

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 […]
