Resumo: | In this study, 300 1 day-old male Cobb chicks were used to evaluate, with the objective of evaluating the effects of phytogenic additives on performance, gut integrity and immune system of broilers inoculated with Salmonella enterica serovar Enteritidis (SE). The birds were divided into five treatments with six repetitions each. Treatment (Ttm) 1 - group inoculated orally with 0.1 mL of sterile buffered saline 0.85% (placebo), Ttm 2 - phytogenic received additives in the feed at a dosage of 0.10 kg/ton feed of the initial age until 35 days (Contr. FA); Ttm 3 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL Salmonella enterica serovars Enteritidis (Contr. positive SE); Ttm 4 - group inoculated orally with 0,5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL of SE and received as antimicrobial growth promoter (AGP) bacitracin methylene disalicylate at a dosage of 55 ppm in the feed until 35 days of age (SE + AGP); Ttm 5 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5 mL SE received phytogenic additives in the feed at a dosage of 0.10 kg/ton of feed of 1 to 35 days old (SE + FA). Performance was evaluated and six birds for treatment were weighed, sacrificed and the pH of the gastrointestinal tract was measured. Fragments were collected duodenum and jejunum to histomorphometric analysis, morphometric lymphocyte count. There was significant difference in the period 1-35 of the experiment the average weight and weight gain of groups without microbial challenge, and feed conversion in the group feed with phytogenic. We observed greater higher villus height to 14 days in the duodenum and greater villus:crypt to the group that received phytogenic The pH was influenced by the AGP in the colon and caecum. There was no significant effect of treatment on biometry of organs and Salmonella groups. There was lymphoid depletion in spleen, bursa and caecal tonsils was variable, with a predominance of mild and moderate depletion. It is concluded that the additives phytogenic control the effects of SE in broilers as expressed in the performance, especially in the feed conversion, and histomorphometric of the intestine, although it has not prevented the migration of the SE for the lymphoid organs, as well as not stimulate the proliferation of lymphoid cells in broilers. |

As aves foram divididas em cinco tratamentos com seis repetições cada. Tratamento (Ttm) 1 - grupo inoculado por via oral, com 0,1 mL de solução salina tamponada e esterilizada a 0,85% (Placebo); Ttm 2 - recebeu os aditivos fitogênicos na ração na dosagem de 0,10 kg/ tonelada de ração da fase inicial aos 35 dias de idade (Contr. AF); Ttm 3 - grupo inoculado via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de Salmonella enterica sorovar Enteritidis (Contr. positivo SE); Ttm - 4 - grupo inoculado por via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de SE e que recebeu como antimicrobiano promotor de crescimento (APC) a bacitracina metil dissilicato na dosagem de 55 ppm na ração até os 35 dias de idade (SE + APC); Ttm 5 - grupo inoculado por via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de SE que recebeu os aditivos fitogênicos na ração na dosagem de 0,10 kg/ tonelada de ração do 1º aos 35 dias de idade (SE + AF). Foram realizadas análises de desempenho e seis aves por tratamento foram pesadas, sacrificadas e o pH do trato gastrintestinal foi aferido . Coletou-se fragmentos de duodeno e jejuno para análises histomorfométricas, morfometrias e contagem de linfócitos. Observou-se diferença significativa, durante o período de 1-35 final do experimento no peso médio e no ganho de peso dos grupos sem desafio microbiano, além de melhor conversão alimentar no grupo alimentado com aditivos fitogênicos. Observou-se maior altura dos vilos aos 14 dias no duodeno e maior relação vilo:cripta para o grupo que recebeu fitogênicos O pH foi influenciado pelo APC no cólon e ceco. Não houve efeito significativo dos tratamentos sobre a biometria dos órgãos e Salmonella nos grupos. Observou-se a depleção linfóide nos baços, bursas e tonsilas cecais foi variável, com predominância de depleção discreta e moderada. Conclui-se que os aditivos fitogênicos controlam os efeitos da SE em frangos de corte como expresso nos dados de desempenho, especialmente na conversão alimentar, e dados histomorfométricos do intestino, embora não tenha impedido a migração da SE para os órgãos linfóides, bem como não estimulam a proliferação de células linfóide nos frangos de corte.Submitted by Luanna Matias (lua_matias@yahoo.com.br) on 2015-03-03T14:36:30Z No. of bitstreams: 2 Dissertação - Ana Caroline de Souza Barnabé - 2012.pdf: 955092 bytes, checksum: 1c7e4c5347d5c7994c39252d1f1f2fef (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2015-03-04T12:04:33Z (GMT) No. of bitstreams: 2 Dissertação - Ana Caroline de Souza Barnabé - 2012.pdf: 955092 bytes, checksum: 1c7e4c5347d5c7994c39252d1f1f2fef (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Made available in DSpace on 2015-03-04T12:04:33Z (GMT).

description |
In this study, 300 1 day-old male Cobb chicks were used to evaluate, with the objective of evaluating the effects of phytogenic additives on performance, gut integrity and immune system of broilers inoculated with Salmonella enterica serovar Enteritidis (SE). The birds were divided into five treatments with six repetitions each. Treatment (Ttm) 1 - group inoculated orally with 0.1 mL of sterile buffered saline 0.85% (placebo), Ttm 2 - phytogenic received additives in the feed at a dosage of 0.10 kg/ton feed of the initial age until 35 days (Contr. FA); Ttm 3 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL Salmonella enterica serovars Enteritidis (Contr. positive SE); Ttm 4 - group inoculated orally with 0,5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL of SE and received as antimicrobial growth promoter (AGP) bacitracin methylene disalicylate at a dosage of 55 ppm in the feed until 35 days of age (SE + AGP); Ttm 5 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5 mL SE received phytogenic additives in the feed at a dosage of 0.10 kg/ton of feed of 1 to 35 days old (SE + FA). Performance was evaluated and six birds for treatment were weighed, sacrificed and the pH of the gastrointestinal tract was measured. Fragments were collected duodenum and jejunum to histomorphometric analysis, morphometric lymphocyte count. There was significant difference in the period 1-35 of the experiment the average weight and weight gain of groups without microbial challenge, and feed conversion in the group feed with phytogenic. We observed greater higher villus height to 14 days in the duodenum and greater villus:crypt to the group that received phytogenic The pH was influenced by the AGP in the colon and caecum. There was no significant effect of treatment on biometry of organs and Salmonella groups. There was lymphoid depletion in spleen, bursa and caecal tonsils was variable, with a predominance of mild and moderate depletion. It is concluded that the additives phytogenic control the effects of SE in broilers as expressed in the performance, especially in the feed conversion, and histomorphometric of the intestine, although it has not prevented the migration of the SE for the lymphoid organs, as well as not stimulate the proliferation of lymphoid cells in broilers. |
