“…Similar results were observed by SANCHES et al (2006) and ASSIS et al (2014), who evaluated the inclusion of prebiotics β-glucan, or antibiotics in diets for weaned piglets and also reported no effect on CD in the duodenum and jejunum of pigs. However, HU et al (2013) observed shorter villus and deeper crypt on d 3 and 7 post-weaning, but according to these authors the damaged intestinal morphology was already recovered to preweaning values on day 14 post-weaning.…”

“…Similarly, SANCHEZ (2006) reported no effect on ADFI of piglets from 23 to 58 days of age fed diets containing antibiotics, probiotics (Bacillus subtilis), prebiotics (MOS), and symbiotic. In a study to assess the inclusion of sodium butyrate (0.1, 0.2 and 0.4%) in diets for pigs weaned at 28 days of age, ASSIS et al (2014) evaluated diets containing mannanoligosaccharides (MOS), beta-glucans and antibiotics for gilts from 21 to 34 days of age and also reported no effect on ADFI.…”

This experiment was conducted to evaluate the effect of growth promoter additives an alternative to antibiotics on performance, intestinal morphology and on microbiota of 21-to-35-day-old piglets. A total of 160 commercial crossbred piglets (males and females) with initial weight of 6.10±0.709kg were allotted in a completely randomized design with five treatments: Basal diet - Negative Control (NC); Basal diet + antibiotic (PC); Basal diet + mannanoligosaccharides (MOS); Basal diet + organic acids (OA), Basal diet + mannanoligosacharides + organic acids (MOS+OA), eight replicates and four piglets per experimental unit. The inclusion of additives in the diets had no effect (P>0.05) on the final average weight of piglets. Similarly, no effects (P<0.05) were observed on average daily feed intake and on average daily weight gain. The feed conversion improved (P<0.01) with the inclusion of additives in the diets compared to piglets fed with the NC. There was no effect (P>0.05) of the dietary additives on intestinal morphology and microbiota composition (enterobacteria and lactobacilli). Use of antibiotics, prebiotics, organic acids or prebiotics associated with organic acids in the diet improves feed conversion of piglets from 21 to 35 days of age. The additives have no major effects on piglets’ intestinal morphology and microbiota.

“…The results match those reported by Grela et al (2006), who, when assessing the frequency of diarrhea in piglets from birth to 84 days of age, found that adding 3,000mg/kg and 5,000mg/kg mannanoligosaccharide and fructooligosaccharide, respectively, decreased diarrhea incidence. Such results are attributed to the possible improvement of the immune system and epithelium integrity (Wu et al, 2017) and match the findings by Budiño et al (2010), Assis et al (2014), andLuna et al (2015), who used fructooligosaccharides, mannanoligosaccharides, and β-glucans + mannanoligosaccharides versus GPA respectively, and found no differences among the treatments.…”

This study aimed to assess different prebiotic concentrations and principles, in addition to calcium butyrate, aiming to replace colistin as a growth promoter. The sample consisted of 120 piglets weaned at 22 days old with mean initial weight of 5.475 ± 0.719kg. The animals were assigned to random blocks in six treatments corresponding to the use of the following dietary additives: T1) colistin (40 ppm); T2) β-glucan/mannan-oligosaccharides (0.2%); T3) calcium butyrate (0.1%); T4) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.01%) + galactooligosaccharides (0.09%); T5) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.03%) + galactooligosaccharides (0.07%); and T6) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.05%) + galactooligosaccharides (0.05%). The results showed no difference among treatments for the performance parameters in any of the phases evaluated. For diarrhea incidence and intensity, the results indicated that the treatments with alternative additives had similar effects as the group treated with colistin. A significant difference was found for the profile of propionic acid (0.23% colistin and 0.32%, 0.36%, 0.37% additives) and total fatty acids (0.67% colistin and 0.97% additives) values in the caecum. The supplementation with different compositions and concentrations of prebiotics and butyric acid may viably replace colistin in controlling diarrhea and modulating volatile fatty acid production in the caecum.

“…Os prebióticos também são aditivos, porém são ingredientes que não são digeridos pelas enzimas presentes no trato gastrointestinal dos animais, todavia, são fermentados pelas bactérias e gera substancias que estimulam o crescimento e atividade de bactérias benéficas para o hospedeiro, inibindo assim o crescimento e colonização de bactérias patogênicas (Assis et al, 2014& Sessin, 2018) Brito et al, (2013, citam em sua revisão que o efeito do aditivo probiótico e prebiótico sobre desempenho de leitões desmamados aos 23 dias mostraram que essa adição proporcionou desempenho dos animais semelhantes quando comparado ao tratamento com antibióticos. O seu uso ainda melhorou a qualidade da carcaça, apresentando uma carne com menor perda de água durante o processo de cozimento, melhor retenção e firmeza da carne.…”

Diante dos desafios encontrados atualmente na produção de suínos, o uso de aditivos tornou-se uma das principais estratégias nutricionais que auxiliam na diminuição do uso de antibiótico nas dietas de suínos. Um dos principais aditivos utilizados na nutrição de suínos são as leveduras, que têm em sua composição produtos que podem atuar como prebióticos e probióticos. Com isto, objetivou-se realizar uma revisão de literatura sobre o uso de leveduras na dieta de suínos nas fases de creche, crescimento e terminação. As variabilidades de estudos demonstram resultados diferentes em todas as fases de produção, pois fatores como o tipo de levedura utilizada, o ambiente que os animais estão submetidos e a variabilidade de espécies e microrganismos dos aditivos podem impactar nos resultados esperados, também o tipo de processamento que a levedura é submetida pode influenciar no seu mecanismo de ação, o que pode ter impacto na eficiência da mesma. Estudos demonstram que as leveduras e seus produtos melhoram a saúde intestinal por modular a microbiota, aumentando o tamanho das vilosidades e profundidade das criptas intestinais, reduzindo também as bactérias patogênicas. Com isso é possível concluir através da revisão realizada, que há necessidade de mais estudos que possam demonstrar a eficiência do uso das leveduras na saúde intestinal dos animais e desempenho zootécnico.
