| ABSTRACT This experiment was conducted to evaluate the effects of dietary nitrogen-corrected apparent metabolizable energy (AMEn) levels on meat-type quail performance and carcass traits from 1 to 14d of age. A total of 1120 not sexed meat-type quails were randomly distributed to seven treatments, with eight replicates with 20 quails each. A basal corn and soybean meal-based diet was formulated to meet or exceed quail nutritional requirements, except for ME. Graded levels of soybean oil were added to the basal diet in replacement, to sand, to obtain dietary treatments (2,600; 2,700; 2,800; 2,900; 3,000; 3,100 and 3,200 KcalAMEn/kg diet). Data were analyzed as one-way ANOVA and optimum AMEn levels were estimated using polynomial regression model. Increasing... |

| The objective of this study was to evaluate the performance of male broilers between 21 and 42 days of age fed diets supplemented with an enzyme blend (EB) and containing graded levels of sunflower meal (SFM). In total, 1920 male Cobb broilers were distributed according to a randomized block experimental design in a 4 x 3 factorial arrangement (four SFM dietary levels vs. three feed formulations) with eight replicates of 20 birds each. Dietary SFM inclusion levels were 0, 8, 16, and 24%. Feed formulation included one negative control diet (NC) formulated to supply broiler nutritional requirements, considering EB nutritional matrix values; a diet formulated as the first one, but with the addition of 0.5% EB (NC+EB); and the third diet (positive control -... |

| ABSTRACT Two trials were performed to evaluate the effects of an enzyme complex (EC) on broiler performance, metabolizable energy, and phosphorus and nitrogen balance. In the first trial, 960 one-day-old male Cobb broilers were randomly distributed in a 3 x 2 factorial arrangement (three nutritional levels and the inclusion or not of EC), totaling six treatments with eight replicates of 20 birds per pen, and reared until 42 days of age. The control diet was formulated to meet the broilers' nutritional requirements. The other diets contained reduced available phosphorus (P), metabolizable energy, and amino acid levels, considering 100% and 150% of the EC nutritional matrix. The inclusion of the EC (200 g/ton) resulted in better broiler performance,... |

| ABSTRACT This study aimed at evaluating four dietary L-Glutamine (L-Gln) or L-Gln plus L-Glutamate (L-Glu) supplementation programs on the performance, breast yield, and uniformity of broilers. A total of 2,112 one-d-old male Cobb 500(r) broilers were distributed according to a randomized block design in a 2 × 4 factorial arrangement (L-Gln or L-Gln plus L-Glu × 4 supplementation programs), totaling eight treatments with 12 replicates of 22 broilers each. The supplementation programs consisted of the dietary inclusion or not of 0.4% of L-Gln or L-Gln plus L-Glu for four different periods: 0 days (negative control), 9d, 21d, and 42d. Feed intake (FI, g), body weight gain (BWG, g), feed conversion ratio (FCR, kg/kg), coefficient of variation of body weight... |

| ABSTRACT This study was conducted to estimate the dig. valine to lysine (Val:Lys) ideal ratio for meat-type quails from 15 to 35 d of age. A total of 385, 15-day-old not sexed quails, were randomly assigned to five treatments, each one seven times replicated with eleven quails per experimental unit. Experimental treatments consisted of five dig. Val:Lys ratios (0.65; 0.70; 0.75; 0.80 and 0.85). Ideal dig. Val:Lys ratio was estimated using polynomial regression and linear broken-line regression model. Significant effect was considered when p≤0.05. Feed conversion ratio was not affected by dig. Val:Lys ratios in any of the assessed phases. From 15 to 21 d of age Val:Lys ratios increased linearly feed intake, weight gain and body weight. From 15 to 28 d of... |

| ABSTRACT This study was conducted to determine the optimum standardized ileal digestible isoleucine to lysine (SID Ile:Lys) ratio for meat-type quails from 15 to 35 d of age. Three hundred fifty not-sexed meat-type quails (Coturnix coturnix coturnix) were randomly assigned into five treatments, with seven replicates of 10 quails each. An isoleucine-deficient corn-soybean meal-based diet was formulated and graded supplemented with L-isoleucine (99%) to obtain diets containing SID Ile:Lys ratios of 55,61, 67, 73, and 79%. Data were analyzed as one-way ANOVA and optimum SID Ile:Lys was estimated by polynomial (linear and quadratic) regression. Statistical differences were considered when p<0.05. Quail performance from 15 and 21 d and 15 and 28 d of age was... |

| ABSTRACT This study was conducted to determine the optimal standardized ileal digestible arginine to lysine (SID Arg:Lys) ratio for Japanese quails in the egg-laying phase. A total of two hundred forty-five 35-week-old Japanese quails (181 ± 1.30 g initial body weight) were randomly assigned to five treatment groups with seven replicates of seven quails. Graded levels of L-Arginine were added to a basal diet in order to produce five SID Arg:Lys ratios (101, 106, 111, 116 and 121%). Collected data were analyzed as one-way ANOVA and optimal ratio was estimated using polynomial regression model (linear and quadratic) based on performance traits. Statistical differences were considered for p<0.05. Graded SID Arg:Lys ratios did not affect performance traits... |
