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...

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),...

Autores: Lima,Matheus Ramalho de; Costa,Fernando Guilherme Perazzo; Guerra,Ricardo Romão; Silva,José Humberto Vilar da; Rabello,Carlos Bôa-Viagem; Miglino,Maria Angelica; Nogueira,Eduardo Terra; Pinheiro,Sarah Gomes.
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,...

Efeitos da relação metionina + cistina: lisina sobre os desempenhos produtivo e econômico e a qualidade interna e externa dos ovos antes e após 28 dias de armazenamento
Provedor de dados: 96
Autores: Jordão Filho,José; Silva,José Humberto Vilar da; Silva,Edson Lindolfo da; Araujo,Daniel de Magalhães; Ribeiro,Marcelo Luís Gomes; Lima,Matheus Ramalho de.
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...

Nutritional reduction of protein and usage of enzyme in the diet of light layers
Provedor de dados: 96
Autores: Lima,Matheus Ramalho de; Costa,Fernando Guilherme Perazzo; Goulart,Cláudia de Castro; Pinheiro,Sarah Gomes; Souza,Rafael Barbosa de; Morais,Sérgio Antonio de Normando; Lima,Raffaella Castro.
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...
