Influence of feed enzyme preparation “Ficord-2012-f” on morphological and biochemical indicators of blood of broiler chickens

The work is devoted to the study of the use of the feed enzyme preparation "Fecord-2012-F" produced in the Republic of Belarus to reduce the cost of the diet, increase the digestibility of feed nutrients, due to the inclusion in the formulation of indigestible components, such as sunflower meal, barley, wheat, triticale, rye, oats . The nutritional value of the feed enzyme preparation "Fecord-2012-F" was assessed on 4000 broiler chickens of the Ross 308 cross, in the conditions of the Ostrovskaya poultry farm in the Pskov region. Studies have shown that feeding broiler chickens with 0.5% enzyme preparation "Fecord-2012-F" per 1 ton of wheat-soybean-based feed ensured higher growth rates of broilers throughout the entire growing period. The increase in live weight of broilers in the experimental group that was given the feed enzyme preparation “Fecord-2012-F” was statistically significant (P ≥ 0.001). Feed consumption per unit of growth of broiler chickens in the experimental group decreased compared to the control group. The safety of chickens treated with the enzyme was relatively high and was above 98.9%. The inclusion of the enzyme preparation “Fecord-2012-F” in the feed had a positive effect on the morphological composition of the blood of broiler chickens. These data indicate the positive effect of the feed enzyme in the chicken diet on the digestibility of protein, fat, fiber, BEF, and better use of nitrogen, absorption of calcium and phosphorus. During the study, we found that the enzyme feed preparation “Fecord-2012-F” increases the digestibility and assimilation of feed nutrients and reduces the negative impact of anti-nutrients. To a certain extent, the deficiency of digestive enzymes is replenished in the early stages of broiler rearing, when the production of their own enzymes is difficult, as well as in the case of feeding feed with a high content of non-starchy polysaccharides.
