1. Effect of dietary amino acid composition from proteins alternative to fishmeal on the growth of juveniles of the common snook, Centropomus undecimalis
ABSTRACT This study investigated the effect of dietary amino acid composition from proteins alternative to fishmeal on the growth performance of the common snook, Centropomus undecimalis. Fish of 10.79±0.71 g (n = 150) were stocked in 15 shaded outdoor tanks of 1 m3. The basal diet contained 643.4 g kg−1 salmon byproduct meal (SML) and 200.0 g kg−1 soy

2. Dietary level of cull pinto beans on nutrient digestibility and animal performance of finishing hair lambs
ABSTRACT The objective was to evaluate the effect of cull pinto beans (CPB) (Phaseolus vulgaris) on performance of feedlot lambs. Seventy-two crossbred hair-breed lambs (Dorper × Pelibuey and Kathadin × Pelibuey) were used (75±6 days old and 18.7±3.89 kg of initial body weight). Animals were fed twice daily. Diets consisted of 20% alfalfa hay and 80% con

5. Slow-release urea in diets for lactating crossbred cows
The objective of this study was to evaluate the performance of F1 (Holstein × Zebu) cows in lactation according to different levels of substitution of soybean meal for a protein equivalent non-protein nitrogen originated from slow-release urea (SRU). Eight F1 (Holstein × Zebu) cows in the first third of lactation, with an average milk yield of 12.7 kg (±3

6. Performance and carcass characteristics of Nellore young bulls fed different sources of oils, protected or not from rumen degradation
The objective was to evaluate the addition of vegetable oils protected or not from rumen degradation in the diet of feedlot-finished young bulls and their effects on performance and carcass characteristics. Thirty-five Nellore males of 402.69±14.90 kg initial weight and 18±2 months of age were utilized. The animals were confined for 96 days, after 28 days

7. Obtenção e caracterização de hidrolisados enzimáticos de proteínas do farelo de soja
Soy protein concentrate (SPC) is used as an ingredient for food and animal feed. It is obtained from defatted soybean meal by extracting sugars and other soluble compounds. The main consequence of the extraction process is removal or inactivation of most anti-nutritional factors of soybean, which makes this product can be used in place of animal proteins in

9. Evaluation of mathematical models to describe growth of grazing young bulls
The objective of this study was to evaluate the use of different mathematical models to describe growth of grazing beef cattle. Data of 20 Nellore bulls with initial weight of 129±28.1 kg and final weight of 405±62.0 kg were used. The animals were randomly divided into four plots and placed on B. decumbens Stapf pastures. Three plots received concentrate s
