Extratos fitogênicos como alternativos aos antibióticos promotores de crescimento em dietas para frangos de corte

Abstract in Portuguese
Com as restrições e proibições dos APC o uso de aditivos promotores da saúde e integridade intestinal como ácidos orgânicos e extratos fitogênicos vem aumentando, eles são capazes de melhorar os índices produtivos dos animais, como consequência do controle das doenças entéricas subclínicas, modulação da microbiota intestinal e modulação do sistema imune intestinal. O objetivo desse estudo foi avaliar a ação de diferentes extratos fitogênicos sobre a integridade intestinal e o desempenho zootécnico de frangos de corte em comparação aos antibióticos promotores de crescimento convencionais. Nesse experimento foram utilizados 864 pintinhos machos, Cobb distribuídos em um delineamento inteiramente casualizado, contendo oito tratamentos (T1 dieta padrão (DP) sem anticoccidiano, T2 DP sem anticoccidiano, T3 DP com anticoccidiano e Antaphyt ® 400g/ton fase 1 e 200g/ton fase 2 com anticoccidiano, T4 DP com anticoccidiano e Antaphyt® 200g/ton + glicerídeo de ácido butírico, T5 DP com anticoccidiano e aju inarina 100g/ton, T6 DP com anticoccidiano e extratos de mamona e castanha de aju, T7 DP com anticoccidiano e enramicina e T8 DP com anticoccidiano), contendo nove repetições de 12 aves cada, experimento teve a duração de 41 dias. Aos 14 dias todos os pintinhos, exceto os do T1, foram inoculados com coccidiose. O Tratamento 3 foi o que apresentou a melhor resultado em relação a conversão alimentar dentre os tratamentos com aditivos, sendo 11,3% (equivalente a 178g) melhor em relação ao tratamento que consumiu a enramicina. O Antaphyt MO demonstrou os melhores resultados em relação a conversão alimentar e demonstrou ser um excelente aditivo devido as características positivas de sinergia do lúpulo, alcaçuz e goma arábica sobre a integridade e saúde intestinal.

Phytogenic extracts as alternatives to growth-promoting antibiotics in diets for broiler chickens

Abstract in English
With the restrictions and prohibitions of APC, the use of additives that promote health and intestinal integrity such as organic acids and phytogenic extracts has been increasing, they are capable of improving the production rates of animals, as a consequence of the control of subclinical enteric diseases, modulation of the intestinal microbiota and modulation of the intestinal immune system. The objective of this study was to evaluate the action of different phytogenic extracts on the intestinal integrity and zootechnical performance of broiler chickens in comparison to conventional growth-promoting antibiotics. In this experiment, 864 male Cobb chicks were used, distributed in a completely randomized design, containing eight treatments (T1 standard diet (DP) without anticoccidial, T2 DP without anticoccidial, T3 DP with anticoccidial and Antaphyt® 400g/ton phase 1 and 200g/ton phase 2 with anticoccidial, T4 DP with anticoccidial and Antaphyt® 200g/ton + butyric acid glyceride, T5 DP with anticoccidial and sanguinarine 100g/ton, T6 DP with anticoccidial and castor and cashew nut extracts, T7 DP with anticoccidial and enramycin and T8 DP with anticoccidial), containing nine repetitions of 12 birds each, experiment lasted 41 days. At 14 days, all chicks, except those from T1, were inoculated with coccidiosis. Treatment 3 was the one that presented the best result in relation to feed conversion among the treatments with additives, being 11.3% (equivalent to 178g) better in relation to the treatment that consumed enramycin. Antaphyt MO demonstrated the best results in relation to feed conversion and proved to be an excellent additive due to the positive synergy characteristics of hops, licorice and gum arabic on intestinal integrity and health.
