ABSTRACT This study evaluated increasing dietary levels of Black wattle bark extract (BWE) on broiler performance, nutrient digestibility, intestinal histopathological score, and bone quality. A total of 240 male Cobb 500 broilers, eight days old, were distributed into five dietary treatments (0, 300, 500, 700, or 900 mg kg−1 BWE) in a randomized block design, housed in metabolic cages, with eight replicates of six birds each. Performance was evaluated from 8 to 28 days of age, nutrient digestibility from 18 […]

Corn and soybean meal based diets with increasing levels of ground peas, sub-species hortense cultivar Alfetta (0, 20 and 40%), were formulated to evaluate the nutritional value of this ingredient with 18 castrated male pigs of commercial hybrids averaging 40 kg. The study also aimed to determine the apparent digestible and metabolizable energy and nitrogen retentions of peas. A total period of four weeks was used in which body weight gain, feed intake, feed conversion and amount of feces and […]
