Energy metabolism and respirometry of lambs fed sun or shade dried hays of banana crop residues.

We aimed to evaluate the effects of different drying methods for banana residues on the energy metabolism and respirometry of growing lambs. Twenty Santa Inês x Dorper lambs were fed five experimental diets: Tifton 85 grass hay (Control), shade-dried banana leaf hay (LH Shade), shade-dried pseudostem banana hay (PH Shade), sun-dried banana leaf hay (LH Sun), and sun-dried banana pseudostem hay (PH Sun). Nutrient intake and digestibility were assessed in metabolic cages, whereas O consumption and CO, methane, and heat production were measured in a respirometry chamber with animals fed at maintenance and ad libitum levels.

Does macauba cake alter nutrient digestibility and microorganism population in the rumen of sheep?

Twenty Santa Inês male sheep were used in a randomized block design to evaluate the effects of different levels of macauba cake (MC) on nutrient digestibility and the population of microorganism in the rumen. The animals were divided into four groups according to MC levels (0, 10, 20, and 30% of DM) and initial body weight ranging from 32.75 to 52.

Dataset of feed bunk score images of cattle feedlot.

Bunk management is an important technique to minimize the variations in consumption in feedlot cattle and can be performed according to the South Dakota State University classification system. The use of information and communication technology (ICT) can help, in an objective way, in the interpretation of these measurements. We created a dataset with the objective to develop an automatic classification method of feed bunk score.

Performance and microbiota of the digestive tract of Nellore calves supplemented with fungi isolated from bovine rumen.

Background And Aim: In tropical semiarid regions, supplementation with fungi could contribute to rumen modulation, promoting greater production of fibrolytic enzymes and degradation of forage. The objective of this study was to analyze the effect of supplementation with fungi, isolated from the bovine rumen, on the performance and microbiota of the digestive tract of Nellore calves.

Materials And Methods: The experiment was conducted in randomized blocks evaluating eight Nellore calves that were daily supplemented with isolates of and , along with eight calves that were not supplemented.
