| The objective of this study was to determine the chlorine nutritional requirement of Japanese Quails during the laying phase, based on performance and egg quality parameters. A total of 240 Japanese quails were distributed according to a randomized block design, with five treatments and six replicates, with 8 birds each. The experiment lasted 84 days, divided in four cycles of 21 days each. Treatments consisted of a basal diet formulated to meet the nutritional requirements, except for chlorine, and four supplementation levels with ammonium chloride, generating the levels 0.8; 1.6; 2.4; 3.2 and 4.0 g/kg. The parameters evaluated were: feed intake (g/bird/day), egg production (egg/bird/day), egg weight (g), egg mass (g), egg mass conversion (g/g),... |

| The objective of this study was to evaluate the requirement of digestible tryptophan for white laying hens in the production stage fed diets of different digestible tryptophan:digestible lysine ratios, as well as animal performance and histological alterations in their reproductive and digestive systems. A total of 280 white laying hens at 29 weeks of age were distributed in a completely randomized design with five treatments and seven replications with eight birds in each. The treatments consisted of a base feed, formulated with corn, soybean meal and corn gluten meal, and supplemented with the synthetic amino acids L-lysine, DL-methionine, L-threonine, L-isoleucine, L-arginine, and L-valine, so as to meet the nutritional requirements for laying hens,... |

| Avaliou-se o efeito de diferentes relações metionina + cistina (Met+Cis):lisina (Lis) total sobre o desempenho e a qualidade de ovos para poedeiras semipesadas. Foram utilizadas 120 aves da linhagem Lohmann Brown com 44 semanas de idade, alimentadas com rações isonutritivas (17% PB, 2.774 kcal EMAn, 4,28% de Ca e 0,375% Pd) e distribuídas em um delineamento inteiramente casualizado, com cinco repetições e quatro tratamentos, constituídos da seguinte forma: T1 = relação 0,76 ou 0,70% de Met+Cis e 0,92% de Lis total; T2 = relação 0,83 ou 0,71% de Met+Cis e 0,85% de Lis total; T3 = relação 0,85 ou 0,64% Met+Cis e 0,75% de Lis total; T4 = relação 0,86 ou 0,70% de Met+Cis e 0,81% de Lis total. As variáveis de desempenho e o resultado da análise econômica foram... |

| The objective of this study was to evaluate the reduction of protein, the formulation of diets and supplementation of an enzyme complex for laying hens. The layers were distributed in a completely randomized 2 × 2 × 2 factorial arrangement, with two levels of crude protein reduction (0.0 and 4.0 g/kg), two kinds of diet formulation (without and with reformulation, considering 75 kcal of metabolizable energy) and two enzyme supplementations (without and with enzyme complex supplementation), totalizing 8 treatments of 8 layers each, with 7 replications, in a total of 448 laying hens at 30 weeks of age. After data analysis, it was found that the enzyme complex supplementation in the diet of layers improves performance, promotes a similar egg quality and... |

| The aim of this work was to evaluate the effects of the reduction on nutritional levels of diets for semi-heavy hens during the laying peak on performance, egg quality and bone parameters. A total of eight diets were evaluated, each one with five repetitions of eight birds: 1) control: formulated to supply requirements by the birds; 2) control + 0.03% or 600 FTU; 3) 15% crude protein; 2,800 kcal ME; 3.8% Ca and 0.28% aP; 4) diet 3 + 0.03% or 600 FTU; 5) 14% crude protein; 2,750 kcal ME; 3.4% Ca and 0.23% aP; 6) diet 5 + 0.03% or 600 FTU; 7) 13% crude protein; 2,700 kcal ME; 3.0% Ca and 0.18% aP; and 8) diet 7 + 600 FTU. The reduction of the nutritional levels harmed the performance of the birds, particularly egg production and egg mass, which improved by... |
