ABSTRACT The objective of this paper was to investigate the availability of betaine present in fine wheat bran (FWB) in diets for growing pigs. We used thirty crossbred intact males, housed individually in metabolic cages and distributed in a randomized block design, with five treatments and six replicates. Blocks consisted of two periods of 15 days. Average initial body weights were 32.00±1.30 and 44.90±1.32 kg, in the first and second periods, respectively. Treatments were modified only at the level of […]

This trial was carried out to evaluate the effects of feeding Tilapia fillet by-products meal (TF) for piauçu (Leporinus macrocephalus) fingerlings. One hundred and twenty-five fingerlings averaging weight of 0.19 ± 0.004 g and length of 2.37 ± 0.28 cm were assigned to a completely randomized design with five treatments of five replicates. The diets were formulated to contain levels of 0, 5, 10, and 15% of TF and 0% of TF plus methionine. Diets were fed at 10% of […]

The purpose of this work was to evaluate the effect of 8.4 g/day of rumen protected methionine (RPM) or 8.4 g/day of rumen non protected methionine (RNPM) or even of control cows on milk yield and compositon during 90 days of lactation. Six high yielding lactating Holsteins cows (>20 kg/day) in the first and second lactation, with 19 + 6 days of lactation were used in a duplicated latin square design. The cows were fed a total mixed ration composed […]

The objective of this experiment was to evaluate the laying hens performance fed diets with different levels of lysine and sulfur amino acids digestible. A total of hundred and forty-four 24-week-old hens was allotted to a complete randomized design with three treatments, each with eight replicates of six hens. A corn-soybean positive control diet with high amino acids digestibility (HD) was compared to another diet using various by-products to partially replace corn and soybean meal. The second diet was formulated […]
