“…Hermann et al (2003) found no significant difference in performance of starter pigs using the extract of Echinacea purpurea and carbadox in relation to the control diet. Similar results were obtained by Fukayama et al (2005) and Pedroso et al (2005). This last work compared herbal extract based on thyme, clove and oregano in a combination with different concentrations of antimicrobial agents (colistin, bacitracin and olaquindox) and a basal diet without promoters.…”

“…Still, Namkung et al (2004), Oetting et al (2006) and Utiyama et al (2006) observed no differences when using herbal extracts and antibiotics as growth promoters in the diets of piglets. According to studies cited by Pedroso et al (2005), the intestinal microbiota is wide and only 400 species are known, many of which are rarely detected by traditional methods of cultivation. This fact may have created difficulties finding any statistical differences for this variable.…”

“…Diets were isocaloric and isonutrient formulated based on corn, gelatinized corn, soybean meal and powdered milk, and supplemented with vitamins and minerals to meet the requirements of high genetic piglets (pre-starter and initial phase), according to Rostagno et al (2005) (Table 1).…”

-The objective of this work was to evaluate the use of vegetable extract based addictives associated or not to symbiotics as an alternative for antibiotic as growth promoters for piglets at initial phase. It was used 125 pigs of commercial genetic line with initial weight of 7.4 ± 1.1 kg, weaned at 20 days of age, during 50 days. The experimental design used was randomized blocks (initial weight), with five treatments and five replicates with five animals per experimental unit. The experimental diets were a basal diet, without additive, and other four diets, one diet containing antibiotic (colistin + zinc oxide); diet with 0.3% of a symbiotic mixture; diet with 0.3% of a symbiotic mixture plus 0.05% of herbal mix (plant extracts and microencapsulated essential oils); and another diet with 0.3% of symbiotic mixture plus 0.1% of herbal mixture. It was observed that the use of the symbiotic mixture associated to 0.05% of herbal mixture showed positive results, similar to the ones obtained with diets containing antibiotics for the final weight, average weight gain, average daily feed intake and pH of stomach and diarrhea incidence. The use of symbiotics promoted smaller vilous:depth crypt ratio, except when associated to 0.1% of herbal mixture, which was similar to the diet without addictives. There was no differences in the feed conversion, coliform and lactobacillus count in the jejune and in the cecum and in the pH of cecum. The use of herbal mixture associated to symbiotic is a viable alternative for replacing the use of antibiotics as growth promoters for piglets in the initial phase. However, the concentration of the herbal mixture is an important factor to be considered.Key Words: growth promoters, performance, prebiotic, probiotic, swineExtratos herbais e mistura simbiótica em substituição aos antibióticos para suínos na fase inicial RESUMO -O objetivo neste trabalho foi avaliar o uso de aditivos à base de extratos vegetais associados ou não ao uso de simbióticos como alternativa aos antibióticos como promotores de crescimento para suínos na fase inicial. Foram utilizados 125 leitões de genética comercial, com peso inicial de 7,4 ± 1,1 kg, desmamados aos 20 dias, durante 50 dias. O delineamento experimental foi o de blocos casualizados (peso inicial) com cinco tratamentos e cinco repetições com cinco animais por unidade experimental. As dietas experimentais foram uma ração basal, sem aditivo, e outras quatro, uma contendo antibiótico (colistina + óxido de zinco); outra com 0,3% de uma mistura simbiótica; outra com 0,3% da mistura simbiótica e 0,05% de uma mistura herbal (extrato de plantas e óleos essenciais microencapsulados) e outra com 0,3% da mistura simbiótica e 0,10% da mistura herbal. Foi observado que o uso da mistura simbiótica associada a 0,05% da mistura herbal teve resultados positivos e semelhantes aos obtidos com as dietas contendo antibióticos quanto ao peso final, ganho de peso, consumo médio diário, pH do estômago e incidência de diarreia. O uso de simbióticos promoveu menor relação...

“…By comparing the effect of the growth-promoting antibiotic colistin sulphate with acidifiers in a mixture, Braz et al (2011) observed that the antibiotic also resulted in increased cecal pH. Pedroso et al (2005), evaluating the supplementation with the growth-promoting antibiotics zinc bacitracin, colistin, olaquindox, and herbal extracts of clove, oregano and thyme, reported higher abundance of bacteria in pigs fed a diet without growth promoters. In this context, due to its antimicrobial action, the growth promoter, as well as calcium anacardate, may result in a lower microbial population, which would result in lower production of short-chain fatty acids that would reduce cecal pH.…”

The objective of this work was to evaluate the effects of the dietary inclusion of calcium anacardate on the performance, diarrhea incidence, blood parameters, intestinal morphometry, and pH of gastrointestinal contents in piglets from 21 to 42 days of age. Sixty weaned Topigs piglets, with initial weight of 6.049±0.311 kg, were distributed in the following treatments: diet with or without antibiotic growth promoter (zinc bacitracin) and diets supplemented with increasing levels of calcium anacardate (0.4, 0.8, and 1.2%), with six replicates and two animals per experimental unit. No differences in performance (21 to 42 days of age), blood parameters, and villus height:crypt depth ratio were found between piglets fed diets containing calcium anacardate or antibiotic growth promoter. The replacement of the antibiotic growth promoter zinc bacitracin by calcium anacardate results in similar performance in piglets from 21 to 42 days of age, without changes in blood parameters and in the villus height:crypt depth ratio. The dietary inclusion of calcium anacardate does not decrease diarrhea incidence compared with the antibiotic zinc bacitracin.

“…O uso de aditivos antimicrobianos, como ácidos orgânicos e mais recentemente os nucleotídeos, vem sendo utilizado largamente na dieta de leitões, como medida profilática promotora de crescimento semelhante aos antibióticos, atuando de forma a eliminar ou controlar microrganismos prejudiciais ao animal (PEDROSO et al, 2005).…”
