“…Incrementos nos índices de peróxidos com o avanço do período de estocagem também foram observados por Silva et al (1990) no farelo de arroz integral, por Mcgeachin et al (1992) no óleo vegetal, por Racanicci et al (2000) na farinha de carne e ossos e por Fischer et al (2005) no milho triturado, embora os pesquisadores tenham relatado que a inclusão do antioxidante retardou o processo de peroxidação.…”

Este experimento foi conduzido para avaliar a estabilidade oxidativa do farelo de coco (FC) tratado ou não com butil-hidroxitolueno (BHT) e armazenado por 35 dias e estudar o efeito de rações contendo esse ingrediente sobre o desempenho e a qualidade do ovo de poedeiras. Um lote de 200 kg de farelo de coco foi dividido em cinco partes: uma foi armazenada sem a adição de antioxidante e as demais tratadas com 500 ppm de BHT nos dias 0, 7, 14 e 21. A estabilidade oxidativa do farelo de coco foi acompanhada por meio dos índices de acidez e de peróxidos, determinados semanalmente. Após 35 dias de armazenamento, 10% de farelo de coco tratado e não tratado com BHT nos diferentes tempos de armazenamento foi usado na formulação de rações isonutrientes para poedeiras comerciais. Foram utilizadas 180 poedeiras da linhagem Hisex White, distribuídas ao acaso em 5 tratamentos e 6 repetições de 6 aves cada. Os índices de acidez e de peróxidos do farelo de coco armazenado com ou sem BHT aumentaram com o tempo de armazenamento. Contudo, os tratamentos não afetaram o desempenho nem a qualidade dos ovos das aves. O farelo de coco armazenado por 35 dias sem antioxidante, embora sofra oxidação, pode ser usado em níveis de até 10% na ração para poedeiras comerciais.

“…A complete feed for chicken for fattening (21.5 % CP), based on maize, maize gluten meal, dehulled soybean meal and 4 % vegetable oil (40 % polyunsaturated fatty acids) was supplemented with 125 mg ethoxyquin/kg feed and stored for 6 weeks in galvanized metal cans exposed to sunshine (McGeachin et al, 1992). Maximum temperature in the cans ranged from 38 °C to 53 o C and relative humidity from 71 % to 84 %.…”

The additive ethoxyquin contains ≥ 91 % ethoxyquin, ≤ 8 % ethoxyquin polymers and ≤ 3 % pphenetidine. It is intended for use in all animal species as an antioxidant at a maximum content of 50 mg/kg complete feed. Ethoxyquin is rapidly absorbed after oral administration. Ethoxyquin oxidation in feed materials and in animals leads to four main compounds: 2,4-dimethyl-6-ethoxyquinoline, ethoxyquin N-oxide, ethoxyquin quinone imine, and ethoxyquin dimer (detected only in fishmeal and in salmon). Ethoxyquin itself is not genotoxic or carcinogenic, and does not cause developmental toxicity. The lowest NOAEL (based on studies in rats and dogs) is 2 mg/kg body weight per day. The genotoxic profile of the dimer reflects that of ethoxyquin. Ethoxyquin quinone imine shows structural alerts for mutagenicity, carcinogenicity and DNA binding; no conclusion on the absence of genotoxicity of ethoxyquin quinone imine is possible. p-Phenetidine is a recognised possible mutagen.Concentrations of 50 mg ethoxyquin/kg and 11 mg ethoxyquin/kg complete feed might be considered as potentially safe for chickens and breeders and for dogs, respectively. No conclusion on potential safe levels for other poultry, pigs, ruminants, fish and cats is possible. Overall, when considering the presence of p-phenetidine in the additive, no conclusion on any safe level of the additive for target animals can be drawn. An assessment of safety for the consumer is prevented by the lack of exposure data, the absence of a safe level of exposure and the presence of p-phenetidine in ethoxyquin. The respirable mist of ethoxyquin is of low toxicity. Ethoxyquin is not a dermal irritant, but is considered a potential irritant to eyes and other mucous membranes and a skin sensitiser. No conclusion on the safety for the environment can be made. Ethoxyquin is a potent antioxidant; however, no data confirm its efficacy at the proposed use level.

“…Increased addition of the antioxidant is useful for improving meat quality during storage. Fat oxidation was reduced by the addition of synthetic antioxidants in broiler ration due to antioxidants that prevented more damage to ingredients of the ration (Mc Geachin et al, 1992). An important factor influencing the shelf life and meat quality of poultry is lipid oxidation.…”

his experiment was conducted in Alkeraam farm (A private rabbit's farm at Sadat area on the Deseret Alex. Road) cooperating with Environmental Studies and Research Institute farm belonging to University of Sadat City, Menufiya Governorate, Egypt. The aim of this study was to determine the effect of adding natural antioxidant (Senecio glaucus) of 5 or 10 g of powder or extract per kg of basal diet and Butylated Hydroxytoluene (BHT) as industrial antioxidantat a rate of 150 ppm/kg of basal diet on the performance of growing New Zealand White rabbits. A total of 42 rabbits aged 5 weeks were used in this study, with an average weight of 746.8g. The results indicated that the digestion coefficients were insignificantly differed between the experimental groups and the control positive group (T1), except the control negative group (T2) which significantly lower. Also, the results of TDN and DCP showed insignificantly diffracts among the experimental groups except, group T2. Adverse reactions of lipid oxidation test indicated that the extent of fat oxidation in thigh meat after 7 days of refrigerated storage did not differ between all treatments. While, the concentration of mononaldehyde after 90 days of freezing storage of rabbit meat fed on diet containing 5 g of Senecio glaucus / kg (T5) and 1 ml of Senecio glaucus (T7) extract was significantly lower compared with other groups. Also, the rabbits fed on T6 and T7 groups showed the highest value for meat color, taste, odder, flavor and overall acceptance. Improvements in mean of net revenue, economic efficiency and relative economic efficiency in groups fed on Senecio glaucus either powder or extract supplementation and industrial antioxidant compared to control groups. It could be concluded that, the use of Senecio glaucus plant either powder or extract (5 or 10 g/kg ration) as alternative to industrial antioxidants improves growth performance, quality of meat, duration of its frozen storage and reduces nitrogen feces, which preserves the environment and achieves high returns in the economic efficiency of the production process.
