| ABSTRACT This trial was performed to determine the ideal ratio of digestible methionine + cysteine (Met/Lys) with digestible lysine for meat-type quails from 1 to 14 days of age. A total of six hundred thirty, one-day-old, not sexed meat type quails were randomly assigned to six groups of treatments, each one with seven replicates and fifteen quails per experimental unit. A basal diet, methionine + cysteine-deficient, was graded supplemented with DL-Methionine (0.108; 0.169; 0.230; 0.291; 0.352 and 0.413%) to obtain the treatments, represented by six digestible Met/Lys ratios (0.60; 0.65; 0.70; 0.75; 0.80 and 0.85). Data was analyzed using ANOVA and polynomial regression and broken-line models were used to estimate the digestible Met/Lys ideal ratio,... |

| The supplementation of vegetal diets with L-methionine (100% molar), methionine hydroxyl analogue (HMB) (88% molar) or DL-methionine (99% molar) was compared as to the performance of broilers allocated in cages and submitted to cyclic heat stress (CHS). The trial was carried out from 21 to 42 days of age. Two levels of synthetic methionine were supplemented for each methionine source (0.1 or 0.3 %), and the control treatment was not supplemented with synthetic methionine (negative control). Statistical analyses included the negative control treatment or were performed in a 3 x 2 factorial design (sources x levels). Addition of synthetic methionine to the basal level containing 0.63 % of total sulphur amino acids significantly improved feed conversion (FC)... |

| The objective of this trial was to evaluate the bioavailability of DL-2-hydroxy-4-(methyl) butanoic acid (DL-HMBA) and a polyherbal ingredient (PHI) in relation to DL-methionine (DLM) on broilers. Nine hundred male broiler chickens of the Cobb 500 strain were fed from 22 to 42 days of age either a basal diet without industrial methionine supplementation or the basal diet supplemented with DL-HMBA at one of three levels (0.143, 0.286 and 0.429%) or DLM at one of three levels (0.093, 0.186 and 0.279%, each of which is 65% of the respective DL-HMBA level by weight) or PHI at one of the same three levels used for DLM (0.093, 0.186 and 0.279%). The weight gain, feed conversion ratio and relative weights of breast and abdominal fat were improved over that of... |
