During ontogenetic development in birds body in the process of molting juvenile, puberty, and in connection with the violation of oviposition occur metabolism has characterized by decrease activity of hydrolytic enzymes of the gastrointestinal tract and the functional state of the blind gut microbiota. For leveling the aforementioned violations we used biologically active additive humic natural «Humilid» because organic acids humic substances promote digestion, can inhibit the growth of pathogenic bacteria and stimulate growth of natural microflora in the intestines, improve digestion of protein, calcium absorption, and nutrient feed.
Experiment conducted on two groups of chickens eggs productivity directly cross Hayseks brown from 10-day old birds. Chickens experimental group received the drug «Humilid» (based on 2 mg of active substance per kg of body weight), the layout proposed by the manufacturer — Problem Laboratory of humic substances on them. prof. LA Hrystyevoyi DSAU. The experiment took three months following slaughter 30-, 60-, 90- and 120-day years.
If watering chicks preparation «Humilid» gain weight for birds during the experiment were higher than 9.7 %. However, the enzyme activity of mucosa protein in 12 duodenal intestine at all ages was higher , compared with its value in the control group counterparts. In chicks 60- and 120-day old,amylase activity increased by 10 and 18%, and lipolytic activity — increased for 17.56% but only in 60-day ages birds,if we compare with birds in the control group. We saw the positive effect of biologically active additives on the state of natural humic mikrobotsenozis in blind gut of young chickens cross Hayseks brown at critical periods of growth and development, resulting increase in the number of representatives obligate microflora — namely, bifidobacteria and lactobacilli.
