Abstract


In the last years probiotics have constantly increased in importance and aroused growing interest in animal nutrition. Probiotics are live microorganisms thought to be beneficial to the host organism. The bacteria of the probiotic attach to the intestinal mucosa, thereby forming a physical barrier that blocks the attachment of pathogenic bacteria. The mode of action of probiotics in poultry includes maintaining normal intestinal microflora by competitive exclusion and antagonism, altering metabolism by increasing digestive enzyme activity and decreasing bacterial enzyme activity and ammonia production, improving feed intake and digestion and neutralizing enterotoxins and stimulating the immune system. In experiment we research effect of probiotic on the performance of broiler chickens. A total number of 200 one day old broiler chickens were distributed to two dietary groups. Broiler chickens in control group were fed with standard feed mixture and experimental group with probiotics mixed with feed mixture. Body weight and GIT pH were recorded. Average body weight on the end of experiment in experimental group was 1493.6 g and 1689.6 g in control group. Average pH in experimental group was 2.79 in stomach, 6.28 in small intestine, 6.81 and 6.89 in caecum. In control group was average pH 3.54 in stomach, 6.41 in small intestine, 6.74 and 6.80 in caecum.
