Provedor de dados: 96
Autores: Oliveira,Alexsandro Nunes de; Freitas,Ednardo Rodrigues; Filgueira,Thales Marcel Bezerra; Cruz,Carlos Eduardo Braga; Nascimento,Germano Augusto Jerônimo do.
The experiment was conducted to evaluate the effects of limestone particle size and the use of artificial light for laying hens in the second laying cycle. We used 240 Hisex White laying hens at 82 weeks of age in a completely randomized design in a 5 × 2 factorial arrangement, resulting in 10 treatments with 4 replicates of 6 birds. The variables were the five particle sizes obtained by increasing the proportion of thick limestone (0, 25, 50, 75 and 100%) compared with thin limestone and two lighting programs: with and without artificial light. Limestone particle size and light did not affect performance or egg quality. However, there were changes in bird feeding schedule throughout the day as a response to the lighting program. Bone quality, density and...

Objetivou-se com esta pesquisa avaliar os efeitos dos níveis de fibra em detergente neutro (FDN) das rações oferecidas para as aves entre a 7ª e 17ª semanas de idade sobre o desempenho, o desenvolvimento dos sistemas digestório e reprodutor, bem como os efeitos na maturidade sexual, no desempenho e na qualidade dos ovos na fase de postura.Foram distribuídas 1.296 aves em delineamento inteiramente casualizado em esquema fatorial 3 × 2, composto de três níveis de FDN e duas linhagens, com quatro repetições de 54 aves. Foram testados os níveis de 14,5; 16,5; e 18,5% de FDN em aves leves e semipesadas. Ao final da fase de crescimento, as aves foram transferidas para o galpão de postura, mantendo o mesmo delineamento, composto por 14 aves por parcela. Não houve...

Provedor de dados: 96
Autores: Cruz,Carlos Eduardo Braga; Freitas,Ednardo Rodrigues; Farias,Nadja Naiara Pereira; Xavier,Regina Patrícia de Souza; Lima,Jayron dos Santos Correia; Sá,Newton Lima; Braz,Nádia de Melo; Bezerra,Roseane Madeira.
The effects of neutral detergent fiber levels (NDF) (145, 165, 185 g/kg) were assessed on the bone quality of light-weight and medium-weight laying hens. Eight hundred and forty laying hens were distributed in a completely randomized design in a 2 × 3 factorial arrangement (two strains and three NDF levels) with four replications of 35 birds. At the end of the growth phase, birds were transferred to a laying shed in the same experimental design and each experimental plot consisted of 14 birds. For bone assessment, two birds were selected per plot in the 17th week and one bird in the 35th week for slaughter. After slaughter, drumstick and thigh (legs) were removed and after deboning of the femur and tibia, taken to measurement of their length, weight,...

Calcium anacardate in the diet of broiler chickens: the effects on growth and bone quality
Provedor de dados: 124
Autores: Cruz,Carlos Eduardo Braga; Freitas,Ednardo Rodrigues; Aguiar,Germana Costa; Braz,Nádia de Melo; Trevisan,Maria Tereza Salles.
ABSTRACT The aim of this research was to evaluate the effects of adding calcium anacardate (ACa) as a source of anacardic acid to the diet of broiler chickens on the growth, quality and bone composition of the femur and tibia of the birds. A total of 840 male chicks, one day old, were kept in a completely randomised experimental design, with six treatments and seven replications of 20 birds. The following treatments were applied: a diet without the addition of growth promoter (GP), a diet with added GP and other diets with no GP and the addition of ACa at levels of 0.25, 0.50, 0.75 and 1%. The variables under analysis were the weight, length, diameter, Seedor index, and the resistance and deformity of the left femur and tibia of the birds. For bone...

Performance of broiler chickens reared at two stocking densities and coir litter with different height
Provedor de dados: 124
Autores: Lima,Raffaella Castro; Freitas,Ednardo Rodrigues; Gomes,Herbenson Marques; Cruz,Carlos Eduardo Braga; Fernandes,Danilo Rodrigues.
ABSTRACT The objective of this study was to evaluate the performance of broiler chickens reared at two stocking densities and coir litter with different height. A total of 522 one-day male chicks were distributed in a completely randomized design in a 3×2 factorial arrangement, with three litter height (5, 10 and 15 cm) and two densities (10 and 13 birds/m2), with six triplicates. The experimental period lasted 42 days, evaluating pH and litter moisture; performance; carcass traits; bone quality; and intensities of breast, hock and footpad lesions in the birds. Regarding the effect of density, a significant influence was observed only on performance, wherein the birds reared at the density of 13 birds/m2 showed lower intake and weight gain and better feed...

ABSTRACT The aim of this research was to evaluate the inclusion of calcium anacardate (CAC) as a source of anacardic acid in the diet of broiler chickens on blood parameters, and enzymatic and oxidative activity in the liver. A total of 840 male chicks, one day old, were kept in a completely randomised experimental design, with six treatments and seven replications of 20 birds, totalling 140 birds per treatment. The treatments consisted of feed without the addition of growth promoter (GP), feed with GP, and feed with no GP and the addition of CAC at levels of 0.25, 0.50, 0.75 and 1%. The biochemical blood variables to be analysed were uric acid, total cholesterol, HDL, LDL, creatinine, AST, ALT, triglycerides, total erythrocytes, haemoglobin, haematocrit,...

Provedor de dados: 64
Autores: Freitas,Ednardo Rodrigues; Quevedo Filho,Ivan Bezerra; Watanabe,Pedro Henrique; Filgueira,Thales Marcel Bezerra; Cruz,Carlos Eduardo Braga; Tavares,Thaís Cruz Lopes.
Rice is the second largest cereal crop in the world and the by-products resulting from rice processing for human consumption are potential feedstuffs to compose poultry diets. In this sense, it was evaluated the influence of parboiled rice bran (PRB) in diets for Japanese quails in growing phase on the performance and digestibility, besides of residual effects and characteristics of egg quality in laying phase. A total of 324 Japanese quails with 7 days of age were distributed in a completely randomized design, with 6 treatments and 6 replicates of 9 birds. The treatments consisted of 6 isonutritives diets, being a control diet without PRB and the others containing 5, 10, 15, 20 and 25%. At the end of growing phase the birds were allotted in cages and fed...

Provedor de dados: 64
Autores: Cruz,Carlos Eduardo Braga; Freitas,Ednardo Rodrigues; Xavier,Regina Patrícia de Souza; Fernandes,Danilo Rodrigues; Nascimento,Germano Augusto Gerônimo; Watanabe,Pedro Henrique.
The use of alternative foods to replace conventional foods is becoming a source of research for many researchers. The cashew nut meal (CNM) has high energy and protein value, may be a partial substitute for corn and soybean meal for poultry feed. In this context, this research was conducted to evaluate the effect of inclusion of CNM on the utilization of nutrients in the ration for laying hens, as well as the performance and characteristics of the eggs. The study used 180 Dekalb Brown laying hens 27 weeks of age, distributed in a completely randomized design with six treatments and five replicates of six birds. Treatments consisted of a control diet without CNM and others with the inclusion of this food at levels of 5, 10, 15, 20 and 25%. Upon regression...

Provedor de dados: 64
Autores: Freitas,Ednardo Rodrigues; Braz,Nádia de Melo; Watanabe,Pedro Henrique; Cruz,Carlos Eduardo Braga; Nascimento,Germano Augusto Jerônimo do; Bezerra,Roseane Madeira.
Feeding management of laying hens has been focused on the direct influence of nutrient intake on weight gain, especially at growing phase. This study evaluates nutrient digestibility, performance, development of the digestive tract, body composition, and bone quality of two strains of laying hens fed with different levels of neutral detergent fiber (NDF) during the growing phase from the 7th to the 12th week of age. A total of 1,296 birds were distributed in a completely randomized design in a 2 x 3 factorial arrangement (two strains x three levels of NDF) with four replicates of 54 birds per treatment. Semi-heavy (Hy Line Brown) and light-strain (Lohman LSL) pullets were allotted to dietary treatments consisting of 14.50, 16.50, and 18.50% NDF. An...
