Evaluation of the use of essential oils of cinnamon, oregano and eucalyptus in ...
Santo, Alicia Dal; Leite, Felipe; Antoniazzi , Fernanda Danielli Valentini; Pagnussatt, Heloísa; Aniecevski , Edemar; Hoinoski, Gabriel; Mis, GilsoThe restriction use of antimicrobials as growth promoters in the production of broiler chickens has proven to be a major challenge. The use of alternative molecules, which have antimicrobial properties, aims to replace these drugs. Essential oils are molecules with great potential to replace growth promoters. The objective of this trial was to evaluate the use of essential oils derived from Eucalyptus globulus,...
Evaluation of the use of phytogenics in combination or not with yeasts to repla...
Leite, Felipe; Pagnussatt, Heloísa; Santo, Alícia Dal; Valentini, Fernanda Danieli Antoniazzi; Talian, Lucas Eduardo; Lima, Marcos deThe objective was to evaluate the inclusion of a combination of carvacrol + cinnamaldehyde and carvacrol + cinnamaldehyde + yeasts on performance, organ yield, intestinal morphometry and serum biochemical parameters in broilers. 360 female broiler chicks of the COBB 500 strain were used, distributed on the first day of age in a completely randomized experimental design, composed of four treatments: negative con...
Sorption isotherms of ingredients and diets for poultry
Sordi, Carina; Tavernari, Fernando de Castro; Surek, Diego; Sartoretto, Laudete Maria; Petrolli, Tiago Goulart; Teixeira, Carlos Jônatas de SousaThis study aimed to determine sorption isotherms of ingredient and poultry diet. The samples were encapsulated in capsules and dehydrated by oven-drying in a desiccator for more than 24 hours. The samples were transferred to desiccator containing water in the base and placed in the oven, with one sample of each material being removed at incremental intervals. The sample was weighed and for determination of wate...
Novos conceitos em nutrição de aves
Pessôa, Gabriel Borges Sandt; Vieira, Rodolfo Alves; Albino, Luiz Fernando Texeira; Tavernari, Fernando de CastroA grande evolução da avicultura brasileira e o consequente aumento da produção de resíduos, bem como as exigências impostas pela União Europeia, quanto ao controle da excreção de poluentes, resultam na busca de novos conceitos relativos à nutrição animal. Dentre esses conceitos, destaca-se o uso da proteína ideal, da injeção de nutrientes in ovo, da alimentação dos animais em fases e a suplementação de aditivos...
Relação metionina + cistina / lisina digestível para frangos de corte cobb
Bernal, Luis Ernesto Paez; Rostagno, Horacio Santiago; Albino, Luiz Fernando Teixeira; Vieira, Rodolfo Alves; Tavernari, Fernando de CastroEm vista da constante evolução do melhoramento genético de frangos de corte, torna-se necessária a determinação das exigências nutricionais dessas aves, para assegurar seu desempenho. Assim sendo, dois experimentos foram realizados, com o objetivo de avaliar diferentes relações de metionina + cistina / lisina digestível sobre o desempenho de frangos de corte, nas fases de 11 a 21 e 22 a 35 dias de idade. O deli...
Diet supplementation with phytase on performance of broiler chickens
Lelis, Guilherme Rodrigues; Albino, Luiz Fernando Teixeira; Calderano, Arele Arlindo; Tavernari, Fernando de Castro; Rostagno, Horacio SantiagoThe assay was carried out to determine the effect of phytase supplementation on performance of broilers from 1 to 21 and 1 to 40 days of age. Twelve hundred and fifty male broilers (Ross) were distributed in a randomized experimental design, with five treatments, 10 repetitions and 25 birds per experimental unit. The treatments consisted of evaluating the phytase supplementation in diets with reductions in nutr...
Efeito da utilização de farelo de girassol na dieta sobre o desempenho de frang...
Tavernari, Fernando de Castro; Dutra Junior, Wilson Moreira; Albino, Luiz Fernando Teixeira; Rostagno, Horacio Santiago; Vieira, Rodolfo AlvesFoi realizado um experimento para avaliar os efeitos da inclusão de farelo de girassol em rações para frangos de corte sobre o desempenho, o rendimento de carcaça e dos cortes e a viabilidade econômica. O delineamento experimental foi em blocos casualizados com cinco níveis de farelo de girassol (0, 5, 10, 15 e 20% da dieta basal), oito repetições e 20 aves por unidade experimental. As aves e as rações foram pe...
Effect of different digestible isoleucine/lysine ratios for broiler chickens
Tavernari, Fernando de Castro; Lelis, Guilherme Rodrigues; Carneiro, Paulo Roberto de Oliveira; Vieira, Rodolfo Alves; Polveiro, Richard CostaTwo experiments were conducted to evaluate different digestible isoleucine/lysine ratios on diets for broiler chickens in the starter (7 to 21 days) and finishing (30 to 43 days) phases. For the tests, the experimental design was of randomized blocks with seven treatments (six different digestible isoleucine/lysine ratios and a control treatment) and eight repetitions of 25 and 20 birds (COBB males) per experim...
Herbal extracts in diets for broilers
Petrolli, Tiago Goulart; Albino, Luiz Fernando Teixeira; Rostagno, Horacio Santiago; Gomes, Paulo Cezar; Tavernari, Fernando de CastroThe objective of this study was to evaluate the effect of feeding herbal extracts for broilers on performance and histology of the intestinal mucosa and its effects on the profiting from the metabolizable energy of experimental diets. For so, two experiments were conducted. In experiment I, the inclusion of different herbal extracts in diets on performance and intestinal histology of broilers was evaluated, and...
Atualização da proteína ideal para frangos de corte: valina e isoleucina
Tavernari, Fernando de CastroConselho Nacional de Desenvolvimento Científico e Tecnológico; Four experiments were carried out at the Department of Animal Science of Federal University of Viçosa to update the profile of the ideal protein for broiler chickens. The first and second experiment evaluated different digestible valine/lysine ratios in the starter (08 to 21 days) and finishing (30 to 43 days) phases. It was used, in both phases, a ...
