Abstract :

There is no doubt that dietary antibiotics have played a fundamental role in animal production as growth and health promoter. However, due to the emergence of microbes resistant to antibiotics which are used to treat animal infections, the European Commission decided to phase out and ultimately ban the marketing and use of antibiotics as growth promoters in feed. In order to meet market and international health organization demands, the poultry industry is studying alternatives to antibiotics. Probiotics can be listed among these products. The objective of the current study was to isolate lactobacilli from Gastro Intestinal Tract of local poultry and investigate their probiotic properties in vitro and in vivo. The in vitro results showed that the lactobacilli strains survived simulated gastrointestinal conditions and were considered to be acid and bile tolerant. The majority of the strains exhibited good antagonistic activity and have the adhesion ability. The results of the in vivo study showed a significant positive effect (p<0.05) of probiotic on body weight and feed conversion ratio of chickens ISA 15 strain.
