How does the use of organic acids in litter used in chicken production affect the intestinal flora?

Sammendrag

Aim - Characterization of the bacterial flora in faeces from chickens that have been exposed to an acidified and non-acidified wood-derived litter. We try to build up knowledge about how the environmental factors might influence the composition and dynamics of the normal flora. Materials and methods - 1728 healthy chickens of White Italian breed type Roff 208 were divided in two groups, and each group in 6 pens. One group was exposed to a dry wood-derived litter (control) and the other group to a dry wood-derived litter treated with a mixture of sodium lignosulphonate, formic and propionic acid. The intestinal contents from ileum and caeca were collected at different ages (18-, 21-, 25-, 29-, 32 days) in order to study the bacterial community using selective media. Results - Statistical analysis of bacterial counts showed lower counts of Cl. perfringens in the ileum and caeca, Lactobacillus spp. in the ileum and Enterococcus spp. in the ileum in the chickens exposed to the acidified litter. Lactobacillus spp. in the caeca showed higher counts in the chickens exposed to the acidified litter. We found no difference between the two litters in the case of Escherichia coli both in ileum and caeca, and of Enterococcus spp. in caeca. Conclusions and discussion – In general, exposing the chickens to an acidified litter lowers the bacterial number, especially in the ileum. One could think that the reduction of Clostridium perfringens and increasing of Lactobacillus spp. have positive effects on the chicken’s health and growth. Our results correlate with bacterial counts performed from the two litters.
