“…In addition, the trend of higher N retention is in accordance with the better growth rate observed at this stage. These results agree with those observed by Poeikhampha and Bunchasak (2011), which showed that dietary supplementation with mannanoligosaccharide and organic acid salts (gluconate and diformate) reduced ammonia production in the large intestine, indicating that less N was available for fermentation. Devi et al (2016) also observed improvement in DM, GE, and N digestibility with diets supplemented only with benzoic acid and not with an additive mix, similarly to the present trial.…”

“…Poeikhampha andBunchasak (2011), Corassa et al (2012), and Giannenas et al (2016), working with different acid and mannanoligosaccharides mixtures, were able to observe the synergistic effect of these additives, mainly on ADG and G:F. The results of the present study did not show synergy of these additives on G:F. However, there was improvement on ADG in the starter phase. This result was not repeated when analysing the whole evaluation period, showing that this gain was diluted in the total period.…”

This study aimed to evaluate the effect of acetic, propionic, and formic (50%) organic acids and mannanoligosaccharide (50%) on growth performance, digestibility, and faecal score in challenged weaned piglets. Twenty male piglets (5.57 ± 0.32 kg of BW; 21-24 days of age) were housed individually in metabolic cages for 28 days in an acclimatised room. The treatments were composed of the inclusion (0.1%; n = 10) or not (n = 10) of additive in the diet. The experimental design was completely randomised with two treatments, 10 replicates, and one piglet per replicate. The nutritional matrix was supplemented with 10% of barley and 35.9 to 34.0% of soybean meal in the pre-starter diet (3-14 days post-weaning) and the starter diet (15-28 days post-weaning), respectively, to cause an intestinal challenge. Diets did not include any antimicrobial or growth promoters. Weekly, the animal and the leftover diet were weighed to evaluate growth performance. Digestibility was evaluated through total faeces and urine collection. Piglets fed diets with additive had 8.7% greater weight gain (P < 0.05) compared to those piglets in the control treatment in the starter phase. For other growth performance responses there was no treatment effect. Similarly, the inclusion of additive in the piglet diets did not affect the faecal score or the energy and nutrient digestibility. In the starter phase and throughout the experimental period, piglets fed diets with additive had 18.37% and 15.07% greater nitrogen (N) intake and 19.53% and 16.05% greater N retention, respectively, compared to piglets in the control treatment (P < 0.05). In conclusion, the addition of additive composed by organic acids and mannan-oligosaccharide does not improve energy and nutrient digestibility but increases the N retention and weight gain in weaned piglets in the starting phase.

ResumoO presente estudo foi realizado com o objetivo de avaliar os efeitos da suplementação de ácidos orgânicos, acético, propiônico e fórmico (50%) e mananoligossacarídeo (50%), sobre o desempenho, digestibilidade e escore fecal de leitões desafiados. Assim, vinte leitões (21 -24 d idade), machos castrados, com peso inicial de 5,57 ± 0,32 kg foram alojados em gaiolas de metabolismo por 28 dias, em sala climatizada. Os tratamentos foram compostos pela inclusão (0,1%; n = 10) ou não (n = 10) do aditivo à dieta. O delineamento experimental foi inteiramente casualizado com dois tratamentos, 10 repetições e um animal por repetição. Utilizou-se 10% de cevada e 35,9 e 34,0% de farelo de soja na matriz nutricional da dieta pré-inicial (de três a 14 dias pós desmame) e inicial (de 15 a 28 dias pós desmame), respectivamente, com o objetivo de causar um desafio intestinal para os leitões. Não foi usado nenhum tipo de antimicrobiano ou promotor de crescimento. Diariamente o escore fecal foi registrado e semanalmente foi feita pesagem das sobras de ração e dos animais para avaliação do desempenho. A digestibilidade foi a...

“…As a natural nutritional supplement MOS may offer a novel approach to balance the intestinal microbiota to beneficial direction and thus may improve overall gut health and welfare (Castillo et al 2008). Also, dietary MOS may maintain the intestinal morphology and absorptive function by increasing the villous height : crypt depth ratio of the gut in weaned pigs (Poeikhampha and Bunchaska 2011). The effect of MOS on pig performance was analysed in several meta-analyses which reported growth rate improvements in nursery rather than in fattening pigs (Miguel et al 2004;Z h a o et al 2012).…”

Effect of mannan oligosaccharide supplementation on blood and intestinal immune cells, bacteria numbers and performance in weaned pigs

In animal production, alternative strategies to the use of antibiotic growth promoters have stimulated research of dietary supplements to increase resistance, reduce post-weaning gut disorders and growth checks in pigs. This study was performed to determine the influence of dietary mannan oligosaccharide as a potential alternative to antibiotic growth promoters in weaned pigs on: (1) proliferation of circulating and intestinal immune cell subsets, (2) incidence and severity of diarrhoea, and (3) performance during 35 days of trial. Forty-six pigs from a commercial farm were divided into two groups comprising 23 pigs each and treated at 4 weeks of age as follows: controls received standard weaner diet, whereas diet for principals was supplemented with 0.2% of mannan oligosaccharide. The pigs were monitored/sampled on daily, weekly or monthly basis for feed efficiency, growth rate, diarrhoea severity scores, blood samples, rectal swabs and intesinal samples for bacterial isolation/counts and immunohistology/ histomorphometry analyses. The principals were heavier (P < 0.05) at 28 days and grew faster between days 7 and 28 compared to controls. Total diarrhoea score recorded in these pigs was decreased by 20.37%. Total bacterial load in jejunum was decreased in these pigs (23 × 10 7 vs. 19 × 10 8 colony forming units/ml) at day 35. Between days 28 and 35 or days 21 and 28, the principals increased in proportions of circulating CD45 + , CD4 + , CD21 + , CD8 + cells (P < 0.01), respectively. These pigs had increased (P < 0.05) the number of CD45RA + cells in interfollicular and follicular areas of ileal Payer's patches at day 35. We concluded that dietary modulation with mannan oligosaccharide resulted in stimulation of immune responses and reduced number of gut microbiota, but not necessarily promoting the growth of pigs.

“…Results showed that dietary mannan products increase the villous height: crypt depth ratio in young broilers [ 33 ] and turkey [ 14 ] and also in weaned piglets [ 34 , 35 ]. In a recent study with nursery pigs, Poeikhampha and Bunchasak [ 36 ] found that 3 g MOS/kg in the diet resulted in increased crypt depth in the jejunum. An increased villous height: crypt depth ratio is generally associated with a bigger absorptive surface; this ratio is, however, usually reduced during the initial post-weaning period [ 37 ].…”

Simple SummaryThe aim of the paper is to provide a review of mannan oligosaccharide products in relation to their growth promoting effect and mode of action. Mannan oligosaccharide products maintain intestinal integrity and the digestive and absorptive function of the gut in the post-weaning period in pigs and enhance disease resistance by promoting antigen presentation. We find that dietary supplementation has growth promoting effects in pigs kept in a poor hygienic environment, while the positive effect of MOS is not observed in healthy pig herds with high hygienic standards. AbstractMannan oligosaccharides (MOSs) are often referred to as one of the potential alternatives for antimicrobial growth promoters. The aim of the paper is to provide a review of mannan oligosaccharide products in relation to their growth promoting effect and mode of action based on the latest publications. We discuss the dietary impact of MOSs on (1) microbial changes, (2) morphological changes of gut tissue and digestibility of nutrients, and (3) immune response of pigs after weaning. Dietary MOSs maintain the intestinal integrity and the digestive and absorptive function of the gut in the post-weaning period. Recent results suggest that MOS enhances the disease resistance in swine by promoting antigen presentation facilitating thereby the shift from an innate to an adaptive immune response. Accordingly, dietary MOS supplementation has a potential growth promoting effect in pigs kept in a poor hygienic environment, while the positive effect of MOS is not observed in healthy pig herds with high hygienic standards that are able to maintain a high growth rate after weaning.
