Influence of dietary valine and leucine levels on the live performance, carcass traits, and meat quality of Cobb MV × 500 males broilers from 32 to 45 d

Recent data has indicated that interactions among the branched-chain amino acids, specifically valine and leucine, can negatively influence broiler performance and carcass traits. Therefore, an experiment was conducted to observe…

Protein Diets for Growing Broilers Created under a Thermoneutral Environment or Heat Stress

…humidity during 8 h/day and 16 h of thermoneutrality, (21–25 °C/ 58–62 % relative humidity). The diets were isocaloric (13.18 MJ/kg), following amino acid corrections. The analyzed variables were: protein…

Excess dietary leucine in diets for growing pigs reduces growth performance, biological value of protein, protein retention, and serotonin synthesis

An experiment was conducted to test the hypothesis that excess dietary Leu affects metabolism of branched-chain amino acids (BCAA) in growing pigs. Forty barrows (initial body weight [BW]: 30.0 ±…

Dietary carbohydrase mixture supplementation and fiber levels on ileal digestibility of nutrients in diets for gestating sows

…this study was to evaluate the effect of a carbohydrase mixture (CM) and dietary fiber level on standardized ileal digestibility (SID) of protein and amino acids (AA) and apparent ileal…

Effects of increasing soybean meal in corn-based diets on the growth performance of late finishing pigs

Three experiments were conducted to determine the effects of increasing soybean meal (SBM) levels by replacing feed-grade amino acids (AA) in corn, corn dried distillers grains with solubles (DDGS), and…

…and other plant protein sources (Swick, 1995; Swick, 1998). Because of the relatively good amino acid profile, it is usually used to balance the dietary amino acid levels with cereal…

Utilization of near-infrared reflectance spectroscopy to predict the digestible lysine, methionine, threonine and nitrogen-corrected true metabolize energy content of mechanically and solvent-extracted soybean meals

…metabolize energy content (TMEN) of SBM. To detect these deviances in nutritional value, broiler or rooster bioassays with subsequent laboratory analyses can be completed to determine digestible amino acid and…
