This study aimed to investigate the impact of dietary inclusion of babassu oil (BO) associated with sunflower oil (SO) on feeding behavior, water intake, and physiological parameters of feedlot lambs. Thirty-five castrated male lambs (16.6 kg ± 3.9 kg) were distributed in a randomized block design with 5 treatments (diets) and 7 replications. The tested diets were oil-free diet (OF), 45 g/kg BO (BO), 30 g/kg BO with an additional 15 g/kg SO (1.5 SO), 22.5 g/kg BO with an additional 22.5 g/kg SO (2.25 SO), and 30 g/kg SO with an additional 15 g/kg BO (3.0 SO) on dry matter (DM) basis. The experimental period lasted 60 days. Animals that received BO diet and the combination of BO with SO had lower intakes of DM and neutral detergent fiber (NDF) compared to the control diet (P

Aim of study: The objective of this study was to evaluate the intake, digestibility, performance, carcass yield, and meat quality parameters in Santa Inês lambs fed cactus pear and bean meal. Area of study: NW Brazil Material and methods: 32 intact Santa Inês male lambs were distributed in a completely randomized design with 4 treatments (diets): control diet (concentrated feed containing corn and soybean meal as energy and protein ingredients); diet containing bean meal as a protein source; diet containing cactus pear as an energy source and; diet containing bean meal and/or cactus pear), using 8 animals per treatment. At the end of the experimental period, lambs were slaughtered with an average body weight of 32.78 kg. Main results: Animal fed cactus pear and bean meal/cactus pear had a higher intake and digestibility for non-fibrous carbohydrates (p0.05). Bean meal can be used as a source of protein concentrate in combination with cactus pear promoting a reduction in the use of corn and soybean in diets for small ruminants. The use of cactus pear in the diets promoted a water supply to the animals. Research highlights: Diets containing cactus pear and bean meal/cactus pear provided higher non-fibrous carbohydrates intake.
