“…As the slaughter age was reduced, some metabolic disorders related to the levels of TAG and plasma lipoproteins, which are linked to sudden death and ascites syndromes, were detected (SQUIRES; SUMMERS, 1993). Hence, ingredients that allow for reductions in TAG and cholesterol levels have been tested in broiler diets (TOGASHI et al, 2008).…”

We evaluated the effect of including 2.5, 5.0, 7.5 and 10.0% mango waste meal (MWM) variety UBA in corn and soybean meal-based diet on the serum lipid profile of broilers. The experimental design was completely randomized, with five treatments and six replicates with 20 birds per experimental unit. Concentrations of creatinine, albumin, total protein, total cholesterol, triacylglycerols (TAG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very-low-density lipoprotein cholesterol (VLDL-C), were evaluated at the ages of 14, 28 and 42 days, with 30 birds evaluated per age. At 14 days, there was no difference serum creatinine, total cholesterol, HDL, triacylglycerols, total proteins or VLDL-C concentrations as compared with control. Albumin concentration was the highest at the MWM inclusion levels of 5.0, 7.5 and 10.0%. At 28 days, triacylglycerols, VLDL-C and LDL-C were the lowestat 7.5% inclusion whereas at 42 days, these same variables were the lowest with addition of 10.0% meal. At 14, 28 and 42 days of age, the VLDL-C, LDL-C and total TAG contents were found to decrease at mango waste meal inclusion levels of 5.0 and 7.5% in the diets, which maybe considered an indicator of improvements in the metabolic conditions of broilers.

“…Produzida pela ação da enzima alinase, a alicina possui ação oxidante, em virtude das duas ligações de oxigênio e enxofre e age como antibiótico destruindo os grupos sulfídricos das enzimas, inibindo a fermentação e estimulando a secreção gástrica, o que resulta em ação profilática contra infecções bacterianas do trato gastrintestinal (Freitas et al, 2001, Togashi et al, 2008, motivo pelo qual é utilizado como promotor de crescimento em criações de suínos e aves (Freitas et al, 2001, Togashi et al, 2008.…”

“…A adição de alho em rações de aves também tem despertado interesse dos nutricionistas como importante aditivo fitogênico (Freitas et al, 2001, Silva et al, 2003, Togashi et al, 2008, Leite et al, 2012. Em experimento realizado nos Estados Unidos, o uso de 3% de alho em pó em rações para frangos de corte não resultou em aumento no ganho de peso e na conversão alimentar (Konjufca et al, 1997), mas mostrou-se eficiente em diminuir os níveis séricos de colesterol em frangos (Togashi et al, 2008).…”

RESUMO.A busca por alimentos seguros e por produtos de origem animal que respeitem os critérios de bem-estar e o meio ambiente ganhou força na última década. Nesse contexto, pesquisas que visam à substituição dos antimicrobianos nas dietas dos animais são desenvolvidas com a finalidade de reduzir problemas econômicos, sanitários e fornecer produtos seguros e de qualidade ao consumidor. Dentre eles estão os probióticos, prebióticos, simbióticos, enzimas, acidificantes e aditivos fitogênicos, que modificam, por estímulo, a biota natural ou inibem por maior competitividade, de uma maneira menos agressiva, a biota intestinal patogênica, promovendo um melhor equilíbrio do meio gastrointestinal e favorecendo a absorção dos nutrientes. Os aditivos fitogênicos são substâncias derivadas de plantas medicinais ou de especiarias, que têm efeito positivo sobre a produção e a saúde dos animais. Estes aditivos podem atuar inibindo o crescimento de microrganismos patogênicos no intestino e melhorar a digestibilidade dos nutrientes. É esperado que nos próximos anos mais pesquisas envolvendo o uso de aditivos fitogênicos na alimentação de aves sejam desenvolvidas para que dessa forma haja maior interesse do setor avícola em fazer uso desses aditivos, em substituição aos antimicrobianos e promotores de crescimento vigentes. O uso de aditivos fitogênicos na avicultura pode ser viável uma vez que possibilita melhores resultados de desempenho e digestibilidade, e permite uma melhoria na viabilidade criatória com consequente melhor índice de eficiência produtiva, principalmente quando existem condições de desafio sanitário. Desta forma, considerando-se o crescente interesse no uso destes aditivos na alimentação de aves, apresentamos uma revisão sobre os compostos fitogênicos e suas principais fontes utilizadas na alimentação de aves.Palavras chave: Antimicrobianos, antioxidantes, compostos fenólicos, flavonoides. Phytogenic additives in broilers chicken nutrition: essential oils and spicesABSTRACT. The search for safe food and products of animal origin that meet the wellness criteria and the environment gained momentum in the last decade. Thus, research aimed at the replacement of antimicrobials in animal diets is developed in order to reduce economic problems, health and provide safe and quality products to the consumer. These include probiotics, prebiotics, symbiotic, enzymes, acidifiers and phytogenic additives, which modify, by stimulating the natural biota or inhibit for greater competitiveness, in a less aggressive way, the pathogenic intestinal biota, promoting a better balance of gastrointestinal half and favoring the absorption of nutrients. The additives are phytogenic substances derived from medicinal herbs or spices that have a positive effect on the production and health of the animals. These additives may act to inhibit the growth of pathogenic microorganisms in the intestine and improve the digestibility of nutrients. It is expected that in coming years more research involving the

In 2006 the European Union banned the feeding of antibiotic growth promoters because of possible risk of drug resistance in human pathogens bacteria. This is the reason for the study of various phytogenic additives and their extracts as a natural source of biologically important compounds. Antimicrobial substances are a commonly included in chicken feed rations. They are used mainly as prevention against various diseases, and also to stimulate growth. The beneficial effects of garlic on animal organism resulting from their antimicrobial, antioxidative and antihypertensive properities. Studies focused on growth, conversion and meat quality of different types of animals indicate its positive effects. In our experiment we studied the influence of garlic extract in a dose of 0, 10 g and 15 g per 1 kg of chicken feed mixture. We focused on weight gains and antioxidant status of an organism. The experiment took 39 days. 54 seven-day-old chickens were included in the experiment. The chickens were weighed once a week, when aged 11, 17, 24, 31 and 38 days, at the same time of the day. The chickens had ad libitum access to feed ration and water. The chickens were taken blood sample at the end of the experiment when 39 days old. Their antioxidant status were measured using ABTS, FRAP and DPPH methods. Our results show that owing to higher concentration of garlic extract in feed ration the antioxidant status of observed chickens was increased. DPPH method showed an increase in antioxidant status of both experimental groups by 38% (a group with a dose of 10 g/kg of mixture) and by 46% (a group with a dose of 15 g/kg of mixture) compared to the control group. When using FRAP method, antioxidant status of both G10 and G15 groups increased by 24%, resp. 16%. No evidential differences in antioxidant activity between the experimental groups and control group were found using ABTS method. The supplement of garlic extract into a feed ration did not have any influence on weight gains of chickens. The aim of our study is to find out an influence of garlic extract on weight gains, feed consumption, and weight of carcass bodies and antioxidant status of broiler chickens. Keywords MATERIAL AND METHODOLOGY Experiment design54 seven-day-old male chickens of Ross 308 type were included in the experiment. Chickens were divided into 3 groups. One group was a control one, other two groups were fed with a feed ration with added garlic extract of concentration 10 and 15 g per 1 kg of feed mixture. Animals and their conditionsChickens were weighed, marked with wing stamps and then divided into groups and put into balancing cages. They were divided into weight-matched groups before the experiment started. Following weightings were done at age of 11, 17, 24, 31 and 38 days, at the same time of the day.Animals could access water and feed ration ad libitum. Feed ration was mixed up from these components: wheat 25%, corn 37%, soya extract grain 28%, sunflower oil 6%, mixture of vitamins and minerals without anticoccidials 3%, monocalciumphosp...
