Influence of iron-containing complexes subjected to ultrasonic impact on the productivity and biochemical parameters of blood serum of broiler chickens
The use of new technologies in poultry nutrition, including micro- and ultrafine particles[1] of trace elements, is a promising way to develop the livestock industry. The aim of the study was to study the effect of experimental bran complexes with the addition of iron on the live weight and blood parameters of broiler chickens. In the course of our research, the positive effect of experimental complexes of the organic form of iron and its microparticles on the increase in live weight and liver metabolism indicators was shown. The « in vitro » digestibility of dry matter with the introduction of organic iron was 84.62 ± 0.37%. Ultrasonic exposure to the product with Fe microparticles resulted in an increase in digestibility by 6.3%, compared with the control. The difference between AsAT activity in groups was statistically significant. Thus, activity decreased by 24.4%, 13.9% and 15.9% in groups I, II and III, respectively, compared with the control. On the 21st day of the experiment, the indicators of growth dynamics were the highest in the control group (6.68%, 17.61% and 14.7% higher than in groups I, II and III, respectively). On the 28th day of the experiment, the indicators of the dynamics of the live weight gain of broiler chickens had the opposite trend, compared with 21 days. The increase in live weight in the control during this period was 34.72%, 10.2% and 15.4% lower than in groups I, II and III, respectively). The results of the study can be used as the basis for innovative solutions for use in agricultural practice.
