“…À medida que as bactérias probióticas e MOS são administrados, a condição de eubiose se torna permanente impossibilitando o estabelecimento de Escherichia coli, Clostridium sp, Salmonella sp, entre outros, aumentando o número de bactérias benéficas produtoras de ácido orgânicos como lático, acético e butírico (OYOFO et al, 1989;ITO et al, 2004).…”

RESUMO -Um experimento com 2400 aves foi realizado para comparar o efeito do uso de probiótico (Bacillus licheniformis e Bacillus subtilis), probiótico mais mananoligossacarídeos (MOS), promotor de crescimento (avilamicina) e uma dieta controle sem aditivos. As dietas básicas eram constituídas por milho e farelo de soja. Foi utilizado um delineamento inteiramente casualizado e os dados obtidos avaliados pela análise da variância e as médias comparadas pelo teste de Tukey ao nível de 5%. Os parâmetros analisados foram ganho de peso, consumo de ração, conversão alimentar e mortalidade. Concluiu-se que na primeira semana o probiótico e o MOS apresentaram um ganho de peso significativamente melhor que os demais grupos. A conversão alimentar do probiótico na primeira semana foi melhor do que a do promotor de crescimento (p<0,05), não diferindo da inclusão de MOS ou da dieta controle. No período total a inclusão do probiótico, de MOS e de promotor de crescimento apresentou melhor ganho de peso do que o controle. Palavras-chave: Frangos de corte, promotores de crescimento, probióticos, prebióticos.ABSTRACT -A study with 2,400 broilers was carried out to compare the effect of probiotics, (Bacillus licheniformis and Bacillus subtilis) probiotics plus mananoligosaccharides (MOS), or growth promoter (Avilamycin) and a control diet without aditives. Diets were based on corn and soybean meal. A completely randomized experimental design was used, and the data were evaluated by analysis of variance and test of Tukey at a level of 5%. The following parameters were measured: feed intake, daily weight gain, feed conversion ratio, and mortality. It was concluded that the effect of the inclusion of probiotics and MOS in the starter diets was significantly higher for the weight gain than the other groups. The feed ratio was significantly higher at the first week as compared to the inclusion of MOS, or to the growth promoter and the control diet. In the full period the effect of the inclusion of probiotics , MOS and growth promoter was significantly higher for the weight gain than the control diet.

“…Indeed, mannose binds to type 1 fimbriae, which corresponds to a filament that many bacteria use to bind to host cells. In chickens supplemented with MOS, salmonellae bind to mannose, thus reducing the carriage density (Oyofo et al, 1989). Depending on the dose, supplementation with FOS and MOS decreased the density of Clostridium perfringens and E. coli in chickens (Kim et al, 2011).…”

In rabbits, the bacterial and archaeal community of caecal ecosystem is composed mostly of species not yet described and very specific to that species. In mammals, the digestive ecosystem plays important physiological roles: hydrolysis and fermentation of nutrients, immune system regulation, angiogenesis, gut development and acting as a barrier against pathogens. Understanding the functioning of the digestive ecosystem and how to control its functional and specific diversity is a priority, as this could provide new strategies to improve the resistance of the young rabbit to digestive disorders and improve feed efficiency. This review first recalls some facts about the specificity of rabbit digestive microbiota composition in the main fermentation compartment, and its variability with some new insights based on recent molecular approaches. The main functions of the digestive microbiota will then be explained. Finally, some possible ways to control rabbit caecal microbiota will be proposed and a suitable timing for action will be defined.

“…A number of carbohydrates (based on glucose, mannose, galactose and fructose) have been shown to have anti-infective properties. Mannose and its polymers are the most commonly used products as feed additives and have been shown to reduce Salmonella colonization in chickens (Oyofo et al, 1989). The large majority of Salmonella contain mannose-specific lectins (Type 1 fimbriae) on the bacterial surface that bind to glycoproteins (rich in mannose) on the intestinal surface.…”

Nutritional strategies to combat Salmonella in mono-gastric food animal production

Nutritional strategies to minimizeSalmonellain food animal production are one of the key components in producing safer food. The current European approach is to use a farm-to-fork strategy, where each sector must implement measures to minimize and reduceSalmonellacontamination. In the pre-harvest phase, this means that all available tools need to be used such as implementation of biosecurity measures, control ofSalmonellainfections in animals at the farm as well as in transport and trade, optimal housing and management including cleaning, disinfection procedures as well as efforts to achieveSalmonella-free feed production. This paper describes some nutritional strategies that could be used in farm control programmes in the major mono-gastric food production animals: poultry and pigs. Initially, it is important to prevent the introduction ofSalmonellaonto the farm throughSalmonella-contaminated feed and this risk is reduced through heat treatment and the use of organic acids and their salts and formaldehyde. Microbiological sampling and monitoring forSalmonellain the feed mills is required to minimize the introduction ofSalmonellavia feed onto the farm. In addition, feed withdrawal may create a stressful situation in animals, resulting in an increase inSalmonellashedding. Physical feed characteristics such as coarse-ground meal to pigs can delay gastric emptying, thereby increasing the acidity of the gut and thus reducing the possible prevalence ofSalmonella. Coarse-ground grains and access to litter have also been shown to decreaseSalmonellashedding in poultry. The feed can also modify the gastro-intestinal tract microflora and influence the immune system, which can minimizeSalmonellacolonization and shedding. Feed additives, such as organic acids, short- and medium-chain fatty acids, probiotics, including competitive exclusion cultures, prebiotics and certain specific carbohydrates, such as mannan-based compounds, egg proteins, essential oils and bacteriophages, have the potential to reduceSalmonellalevels when added to the feed. These nutritional strategies could be evaluated and used in farm control programmes.
