Four ruminally and duodenally cannulated Holstein steers (450 kg) were fed diets with rumen degradable protein (RDP) levels of 50.0 60.0 65.0 and 70.0% associated with a high ruminal degradability starch (cassava by-product meal) were allotted to a 4 × 4 Latin square design for the evaluation of total and partial digestibility of the nutrients, ruminal ammonia concentration and pH. The acid insoluble ash was used as a marker of the duodenal and fecal flow. No effects were observed on […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on performance and nutrient digestibilities of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32.2 kg, respectively, and allotted to a completely randomized design, with four diets and six replications. The dry matter intake in kg/day, %BW and g/kg0.75 was not […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on carcass characteristics, cut yields and carcass muscularity of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32,2kg, respectively, and allotted to a completely randomized design, with four diets and six replications. No effect was observed for the inclusion of whole […]

The objective of this trial was to determine the intake and the total, ruminal and intestinal apparent digestibilidade of dry matter (DM) and its components: organic matter (OM), crude protein (CP), ether extract (EE), in neutral detergent fiber (NDF) and no-fiber carbohydrates (NFC) of the elephantgrass in different regrowth ages and to quantify the microbial protein production. Four crossbred steers fitted with ruminal and abomasal cannula were fullfed with elephantgrass and mineral salt. The experiment was evaluated considering the group […]

Four lactating dairy cows with ruminal cannula and 155 DIM were allotted to a 4 × 4 Latin square and fed twice daily corn silage and concentrate (55:45, %DM) to evaluate the effect of monensin and soybean oil in the diet of lactating cows on the counting of ciliate protozoa beyond establishing correlations between number of protozoa with some parameters of digestion and ruminal fermentation. The treatments consisted of the inclusion of 33 ppm of sodium monensin or soybean oil […]
