ABSTRACT
The purpose of this trial was to assess the influence of homeopathy products on the diet of quails based on egg quality when submitted to different storage periods. Methodology: Two hundred, 45 day old Japanese quails and 80% of production were used, in a completely randomized design comprised of a 4x3 factorial, and 4 diets (basal feed, inert vehicle and 2 homeopathic products: Fertsigo® (Sulphur10 CH, Sepia 15CH ) and Ovosigo® (Belladonna 12CH,Silicea 12 CH, Natrum mur. 30CH, Calcarea phos. 30CH, Sulphur 12CH) and 3 storage periods (0 days, 7 days and 14 days) with ten repetitions of three eggs per treatment. The weight, percentages of yoke, albumen and shell, albumen height and yolk color, specific gravity, Haugh unit, yolk index and shell thickness were evaluated. The data were submitted to variance analysis to verify whether there was a interaction effect between homeopathy factors and storage time, and when absent, the isolated effects. Results: An interaction between the homeopathic products and time was found for the parameters of albumen height and yolk, Haugh unit and yolk index, which reduced over time. For egg weight, yolk, albumen and shell, a significant effect (p<0.05) was found only in the case of homeopathy for the percentages of albumen and shell. For egg and albumen weights, yolk and albumen percentages, specific gravity and colorimetry there was an effect for time, however these parameters reduced over the storage time in days. The addition of the homeopathic based products Ovosigo® and FertSigo® are indicated for the diets of Japanese quail during the laying phase since it resulted in better weights for the egg and its components. Conclusion: The different homeopathic products did not have an influence on conserving the quality of the Japanese quail eggs during the periods evaluated.

As aflatoxinas são responsáveis por grandes prejuízos à saúde de aves comerciais e à produção animal, essencialmente por perda financeira decorrente de diminuição de ganho de peso dos animais. A detoxificação da ração ou de suas matérias-primas, bem como tentativas de diminuir a contaminação fúngica que leva à produção das toxinas, além de técnicas nutricionais, são métodos que podem ser adotados para tentar diminuir os efeitos deletérios sobre os frangos de corte. Sendo assim, o objetivo desta revisão é mostrar o que a ciência fornece como meios de detoxificação e/ou redução de contaminação por fungos; e algumas substâncias naturais que auxiliam a produção avícola na redução de micotoxicoses .
Aflatoxins are answerable for large losses for the health of commercial birds and for the animal production, essentially by financial losses due to animal body weight diminution. Detoxification of feed or its raw materials, well as attempts of diminution of fungal contamination that leads to toxins production, beyond of nutritional techniques, are methods that can be adopted trying to diminish deleterious effects among broiler chickens. This way, the objective of this review is to show what science supplies like ways of detoxification and/or reduction of contamination by fungi, and some natural substances that help poultry production on reduce mycotoxicosis.
ABSTRACT
O presente trabalho teve como objetivo avaliar dietas com óleo essencial de orégano, associado ou não com salinomicina, como alternativa à bacitracina de zinco sobre o desempenho zootécnico de frangos de corte. Foram utilizados 600 pintos de um dia de idade, machos, da linhagem Cobb® 500, criados até 42 dias de idade em boxes com cama de casca de arroz providos de comedouros tubulares e bebedouros nipple. O delineamento foi inteiramente casualizado, com seis dietas e 10 repetições de 10 aves cada. As dietas experimentais à base de milho e farelo de soja foram: controle positivo antibiótico (bacitracina de zinco) + 0,05% de anticoccidiano (salinomicina), controle negativo dieta basal (DB) sem aditivos, DB + 0,05% de salinomicina e 0,03% de óleo essencial de orégano (Orego-Stim®), DB + 0,03% de óleo essencial de orégano, DB + 0,05% de salinomicina e 0,05% de óleo essencial de orégano, DB + 0,05% de óleo essencial de orégano. Não foi encontrado efeito da utilização do óleo de orégano até 21 dias no desempenho das aves. Nos demais períodos, aos 35 e 42 dias, o desempenho das aves tratadas com 0,03% de óleo essencial de orégano + salinomicina apresentou resultados semelhantes ao controle positivo, levando à conclusão de que a dose de 0,03% de óleo essencial de orégano + salinomicina pode substituir a bacitracina de zinco + salinomicina em dietas para frangos de corte.
The inclusion of oregano essential oil, alone or associated with salinomycin, was evaluated as an alternative to zinc bacitracin on the performance of broiler chickens. This study used 600 male Cobb 500® day-old chicks, raised 42 days in boxes with rice hulls, provided with tubular feeders and nipple drinkers. The experimental design was completely randomized with six diets and 10 replications with 10 birds per experimental unit. The diets were based on corn and soybean meal: positive control - antibiotic (zinc bacitracin) + 0.05% anticoccidial (salinomycin), negative control - basal diet (BD) without additives, DB + 0.05% of salinomycin and 0.03% of oregano essential oil (Orego-Stim®), DB + 0.03% of oregano essential oil, DB + 0.05% of salinomycin and 0.05% of oregano essential oil, DB + 0.05% of oregano essential oil. There were no treatment effects on broiler performance until 21 days of age. In the other periods, at 35 and 42 days, the oregano essential oil at 0.03% combined with salinomycin presented similar effects as the positive control, leading to the conclusion that 0.03% of oregano essential oil associated with the salinomycin can replace zinc bacitracin + salinomycin in broiler chicken diets.
