Performance and immune response of broilers born to breeders of different ages ...
Silva,Guilherme Xavier da; Gomides,Larissa Paula Silva; Mello,Heloisa Helena de Carvalho; Carvalho,Fabyola Barros de; Andrade,Maria AuxiliadoraABSTRACT Two experiments were carried out to evaluate the effects of digestible valine supplementation in pre-starter and starter diets on the productivity, nutrient metabolizability coefficient (NMC), and immune response of broilers from breeders of different ages. Experiments I and II were conducted with broilers in the pre-starter (1 to 7 days of age) and starter (8 to 21 days of age) phases, respectively. B...
Performance of brown layers fed reduced dietary protein levels in two rearing s...
Viana,Eduardo de Faria; Souza,Wesley José de; Costa,Miliane Alves da; Arnhold,Emmanuel; Carvalho,Fabyola Barros de; Mello,Heloisa Helena de CarvalhoABSTRACT An experiment was conducted aiming to evaluate the effect of different levels of crude protein, based on the ideal protein concept and two rearing systems, on productive performance of brown laying hens. A total of 400 Hisex Brown laying hens between 30 and 45 weeks of age were distributed in a completely randomized design and a 2×4 factorial arrangement, with main effects including two rearing systems...
USE OF NEEM (Azadirachta indica) AS A SUBSTITUTE FOR ANTIMICROBIAL DRUGS IN BRO...
Assunção,Patricia da Silva; Mello,Heloisa Helena de Carvalho; Mascarenhas,Alessandra Gimenez; Andrade,Maria Auxiliadora; Teixeira,Karla AndradeAbstract In the present work, we carried out an experiment aiming at evaluating the use of Neem as an antimicrobial substance in the feeds of broiler chickens. We used 240 one-day-old Cobb broiler chicks distributed in an entirely casual design, with 4 treatments, 6 repetitions and 10 birds per experimental unit, during a 21-day experimental period. Treatments consisted of a basal diet with no antimicrobial inc...
Supplementation of copaiba or sucupira oils in broiler diets
Noleto,Raiana Almeida; Leandro,Nadja Susana Mogyca; Mello,Heloisa Helena de Carvalho; Conceição,Edemilson Cardoso da; Araújo,Itallo Conrado Sousa deSUMMARY The aim of this study was to evaluate the effect of supplemental copaiba or sucupira oils on broiler performance and intestinal health. A total of 600 one-day old Cobb 500 male broilers were distributed in a completely randomized design with four treatments and six replicates with 25 broilers each. To increase the health challenge, the broilers were reared on reused litter. The treatments consisted of: ...
Antioxidant effect of the guava byproduct in the diet of broilers in the starte...
Oliveira,Maryelle Durães de; Mello,Heloisa Helena de Carvalho; Stringhini,José Henrique; Mascarenhas,Alessandra Gimenez; Arnhold,EmmanuelABSTRACT This work aimed to investigate the antioxidant capacity of the guava agroindustrial waste as a functional additive in broiler feed to improve the performance and meat quality of boilers. The experiment was conducted in a completely randomized design, consisting of four treatments and six replicates with 12 birds. Treatments included different levels of guava byproduct in the feed: 0, 0.5, 1.0, and 1.5%...
EXIGÊNCIA DE METIONINA + CISTINA PARA FRANGAS DE REPOSIÇÃO NA FASE INICIAL (1 A...
D´Agostini,Priscila; Gomes,Paulo Cezar; Mello,Heloisa Helena de Carvalho; Calderano,Arele Arlindo; Sá,Luciano Moraes; Rostagno,Horacio SantiagoResumo Objetivou-se determinar a exigência de metionina + cistina total para frangas na fase inicial e verificar seu efeito sobre a fase de postura. Na primeira fase experimental, 720 aves (50% Lohmann LSL e 50% Lohmann Brown) com uma semana de idade foram distribuídas em delineamento experimental inteiramente casualizado, em esquema fatorial 5 x 2 (níveis de met + cis e linhagens), com quatro repetições e 18 a...
Substitution of blood plasma with soy protein concentrate in piglet diet
Resende,Moisés Queiroz; Mascarenhas,Alessandra Gimenez; Mello,Heloisa Helena de Carvalho; Arnhold,Emmanuel; Teixeira,Karla Andrade; Rufino,Luciana MouraABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight of 7.01±0.294 kg, were distributed in a completely ra...
NÍVEIS DE CÁLCIO E RELAÇÃO CÁLCIO: FÓSFORO EM RAÇÕES PARA POEDEIRAS LEVES DE 24...
Vellasco,Cassia Rampini; Gomes,Paulo Cezar; Donzele,Juarez Lopes; Rostagno,Horacio Santiago; Calderano,Arele Arlindo; Mello,Heloisa Helena de CarvalhoResumo Objetivou-se determinar a exigência nutricional de cálcio e a melhor relação cálcio:fósforo em rações para poedeiras leves de 24 a 40 semanas de idade. Foram utilizadas 324 aves Hy-Line W-36, distribuídas em delineamento inteiramente casualizado, esquema fatorial 3x3, sendo três níveis de cálcio (3,9; 4,2 e 4,5 %) e três relações cálcio/fósforo (9,3; 10,53 e 12,12/1), totalizando nove tratamentos, seis r...
Performance, intestinal histomorphometry, and blood parameters of post-weaning ...
Resende,Moisés Queiroz; Mello,Heloisa Helena de Carvalho; Mascarenhas,Alessandra Gimenez; Arnhold,Emmanuel; Nunes,Romão da Cunha; Teixeira,Karla AndradeABSTRACT Seventy-two barrows were used to evaluate the effects of the use of soy protein concentrate (SPC) in diets of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Piglets were weaned at 21 days of age and distributed in a randomized-block experimental design with four treatments (0, 3, 6, and 9% SPC), six replications, and three piglets per replication. Diets we...
Performance and intestinal characteristics of broiler chicken fed diet with glu...
Nascimento,Gisele Mendanha; Leandro,Nadja Susana Mogyca; Café,Marcos Barcellos; Stringhini,José Henrique; Andrade,Maria AuxiliadoraFive hundred commercial male Cobb broilers were allotted in a randomized blocks design with five treatments, four replicates and 25 chicks per experimental unit in order to evaluate the effects of adding L-glutamine to the diet with no anticoccidial agents and growth promoters. Experimental diets contained L-glutamine at different levels (0.0; 5.0; 10.0; 15.0 or 20.0g/kg), through the experimental period. Exper...
