PROBIÓTICO E/OU PREBIÓTICO SOBRE AS CARACTERÍSTICAS DA LEITEGADA E DA MA TRIZ LACT ANTE Probiotic and/or prebiotic on litter characteristics and sow breastfeeding

RESUMOConduziu-se este trabalho, com o objetivo de verificar o efeito do uso de probiotico e/ou prebiotico na alimentacao dematrizes suinas. Foi utilizado um delineamento inteiramente casualizado com 4 tratamentos e 6 repeticoes (T1= controle; T2=prebiotico; T3= probiotico; e T4= prebiotico + probiotico), sendo cada femea considerada uma parcela. A adicao de probiotico e/ouprebiotico diminuiu o numero de leitoes mumificados. A adicao de prebiotico na racao das matrizes adicionado ou nao de probiotico,elevou a concentracao de proteina no leite no 21o dia de lactacao. No 14o dia de lactacao, as concentracoes de Clostridium perfringensforam menores nas fezes de matrizes que se alimentaram de probiotico. No 21o dia de lactacao, as concentracoes de Bifidobacteriumnas fezes das matrizes foram estatisticamente menores no tratamento com prebiotico (T2). As concentracoes de Enterobacteriaceaeforam maiores nas fezes de matrizes que receberam a adicao de probiotico (T3).Termos para indexacao: Femea suina, Bacillus subtilis, mananoligossacarideo, intervalo desmame-estro, leite.ABSTRACT The objective of the present study was to in determine the effect of probiotic and/or prebiotic added to feed for sows. Anentirely randomized design with 24 sows, 4 treatments and 6 replicates (T1 = control; T2 = prebiotic; T3 = probiotic; and T4 = prebiotic+ probiotic) was used. The addition of probiotic and/or prebiotic decreased the number of mummified piglets. The addition ofprebiotic to sow´s feed, with or without probiotic, increased the concentration of milk protein on the 21st day of lactation. Onthe14th day of lactation, the of Clostridium perfringens was smaller in the faeces of sows fed with probiotic (T3 and T4). On the 21stday of lactation, the concentration of Bifidobacterium in the faeces was statistically lower in sow food with prebiotic (T2).Concentrations of Enterobacteriaceae were higher in the faeces of sows that received probiotic (T3).Index terms: Sow, Bacillus subtilis, mannan oligosaccharides, wean to estrus interval, milk.
