Avaliou-se o desempenho de frangos criados em diferentes temperaturas e alimentados na fase pré-inicial com ração contendo ou não extrato de leveduras e/ou prebiótico. Foram utilizados 1.440 pintos Cobb 500®, machos de 1 dia de idade, criados em diferentes câmaras climáticas. As rações experimentais foram oferecidas somente na fase pré-inicial (1 a 7 dias), de modo que, a partir do oitavo dia, todas as aves receberam a mesma ração. Adotou-se o delineamento experimental inteiramente casualizado, em arranjo fatorial 3 × 2 × 2, composto de 3 temperaturas de criação (alta 34 ± 1ºC; controle 32 ± 2ºC; e baixa 27 ± 2ºC), 2 níveis de extrato de levedura (com ou sem) e 2 níveis de prebiótico (com ou sem). As temperaturas ambiente alta e baixa prejudicaram o...

Autores: Silva,Janaina Della Torre da; Gravena,Rodrigo Antonio; Marques,Rafael Henrique; Silva,Vanessa Karla; Hada,Fabricio Hirota; Moraes,Vera Maria Barbosa de; Malheiros,Ramon Diniz.
The objective of this study was to assess the effect of the inclusion of passionflower (Passiflora alata) in diets on performance, behavior, heterophil/lymphocyte ratio (H/L), corticosterone plasma levels (CPL) and immune response of quails. The study was carried out using 192 birds, distributed in randomized blocks with 4 diets (0, 125, 250 and 375 and 0, 250, 500 and 750 mg of passionflower/kg of feed for the rearing and laying period, respectively), 8 replicates and 6 birds per experimental unit. The rearing period began when birds were 28 days of age and it lasted for 15 days. In this phase, it was evaluated daily feed intake, daily weight gain, feed conversion, viability, tonic immobility time, intensity of injuries, behavior, heterophil/lymphocyte...

Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age

ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the small intestine were measured in chicks aged up to 21 d. We showed that WG was lowest in chicks exposed to longer fasting periods (72 h), although compensatory gains with increasing age were also observed. Unvaccinated chicks performed better at seven days; however, at 21 d of age, a compensatory response led to better FCR in vaccinated birds. Allometric growth of the gastrointestinal tract was affected...

Yeast extract and prebiotic in pre-initial phase diet for broiler chickens raised under different temperatures
Provedor de dados: 96
Autores: Silva,Vanessa Karla; Silva,Janaina Della Torre da; Gravena,Rodrigo Antonio; Marques,Rafael Henrique; Hada,Fabricio Hirota; Moraes,Vera Maria Barbosa de.
The objective of this research was to evaluate the performance, carcass yield and intestinal morphometry of broiler chickens raised under different temperatures that received feed with or without yeast extract and prebiotic in the pre-initial phase. One thousand four hundred and forty one-day old male chicks were used, raised in different climate chambers. Feed with or without the addition of yeast extract and prebiotic was offered only in the pre-initial phase (1 to 7 days). From the eighth day on, every chick received the same feed, readjusted according to usual recommendations. A randomized complete experimental design was used in a 3 × 2 × 2 factorial arrangement, consisting of three environmental temperatures (hot, comfort and cold) and two levels of...

Egg quality during storage and deposition of minerals in eggs from quails fed diets supplemented with organic selenium, zinc and manganese
Provedor de dados: 96
Autores: Gravena,Rodrigo Antonio; Marques,Rafael Henrique; Roccon,Josiane; Picarelli,Juliana; Hada,Fabricio Hirota; Silva,Janaina Della Torre da; Queiroz,Sandra Aidar de; Moraes,Vera Maria Barbosa de.
Three experiments with Japanese laying quails were performed aiming to assess the effect of supplementation with minerals in organic form on the egg quality during storage and the deposition of minerals in eggs. The assessments of each experiment were related to one mineral, thus, experiment 1 assessed the supplementation with selenium in 0.35-, 0.70- and 1.05-mg/kg levels of feed; experiment 2, the supplementation with zinc in 50-, 100- and 150-mg/kg levels of feed; and experiment 3, the supplementation of manganese with 60-; 120- and 180-mg/kg levels of feed. All diets were evaluated compared with a control diet without mineral supplementation. Birds were distributed in a completely randomized experimental design, with eight birds per plot and six...

Effect of supplementation of diets for quails with vitamins A, D and E on performance of the birds and quality and enrichment of eggs
Provedor de dados: 96
Autores: Marques,Rafael Henrique; Gravena,Rodrigo Antonio; Silva,Janaina Della Torre da; Roccon,Josiane; Picarelli,Juliana; Hada,Fabricio Hirota; Queiroz,Sandra Aidar de; Moraes,Vera Maria Barbosa.
The objective of this research was to evaluate the performance of birds and the quality and enrichment of eggs from quails fed diets supplemented with vitamins A, D and E. Three experiments were performed, one for each vitamin, under completely randomized experimental design, with six replicates and eight birds per plot, totaling 192 quails. Performance of birds was evaluated by the daily feed intake, egg weight, laying percentage (%) and food conversion, per kg and dozen of eggs. It was also evaluated the internal quality (Haugh unit, yolk index and yolk and albumen percentages) and external quality (eggshell percentage, egg specific gravity, eggshell thickness and weight) and the concentration of vitamins in egg yolk by using the high performance liquid...

Provedor de dados: 65
Autores: Marques,Rafael Henrique; Gravena,Rodrigo Antonio; Silva,Janaina Della Torre da; Hada,Fabricio Hirota; Silva,Vanessa Karla; Malheiros,Ramon Diniz; Moraes,Vera Maria Barbosa de.
Este estudo teve como objetivo avaliar o efeito da Matricaria chamomila sobre o estresse de codornas japonesas na fase de recria (28 a 42 dias de idade). Foram utilizadas 192 codornas com 28 dias de idades, distribuídas em blocos casualizados e submetidas às dietas com 0, 250, 500 e 750mg de camomila/kg de ração, totalizando quatro tratamentos, com oito repetições e seis aves por parcela. Foram avaliados os parâmetros de desempenho (consumo diário de ração, conversão alimentar e ganho de peso), comportamentais (tempo em imobilidade tônica, ferimentos corporais e agressividade) e fisiológicos (concentração plasmática de corticosterona e relação heterófilo:linfócito). Os resultados obtidos demonstraram que a camomila adicionada na dieta não foi capaz de...
