The commercial egg production has passed through great advances in terms of much more productive ancestries and more healthful feed. All this progress necessary leads of the study of new techniques of production and improvements in the quality feed, aiming the nutritional requirements, one of the alternatives is the use of probiotics in the feed. The objective of this research was to evaluate the performance of commercial laying hens under the action of lactobacillus probiotics. Also, this research studied the optimization of the physical and nutritional conditions to obtain maximum biomass yield of Lactobacillus fermentum, using sugar cane molasses as a low cost culture medium. Several nutritional and physical conditions were tested, and finally, a kinetic study of the biomass production was made in order to confirm the results obtained from the optimizations processes. Results showed that the maximum biomass yield was 5,1 g/L of culture medium with 7% of sugar cane molasses and 2,7% of yeast extract, under ideal fermentation conditions: temperature 37°C, pH 7,0 and 40 hours fermentation. Concerning to the egg production, there was a significant increase in a few months egg production por parte das laying hens that had received the feed with probiotics (Lactobacillus fermentum biomass) and had showed greater resistance to illnessesthat affect the digestive system.
