- Abstract
Productivity parameters of broiler chickens were studied including digestibility and nutrient absorption when replacing feed antibiotics in mixed feed with SafMannan and Immunosan feed supplements which are carbohydrate complexes in yeast cell walls. It was established that the live weight of male and female chickens received studied drugs was higher at the end of fattening, on average, by 0.7 and 1.8%, respectively and in comparison with the control group. According to digestion trial data, the digestion of tested feed was accompanied by an increase in the digestibility of dry matter, crude fat. When SafMannan drug was used in place of feed antibiotic, the digestibility of crude protein was increased. When Immunosan was added to the feed, the digestibility of crude protein corresponded to the control level what is also a significant argument in favor of using it as an alternative to feed antibiotics. Absorption of nitrogen, calcium and phosphorus by broilers of experimental groups was higher than in the control one by 5.8; 21.8 and 2.5%, respectively
