Experience in the use of extrusion additives with a complex of highly dispersed metals in the feeding of meat bulls
The article presents the results on the effect of feeding young cattle in the composition of diets of extruded feed with highly dispersed metal particles on the consumption of feed and nutrient rations, as well as on the growth and development of animals. As follows from the results we obtained, bullheads of the II experimental group received extrudates with highly dispersed metal particles in their ration; they consumed more corn silage as compared to their peers from the control and I experimental groups by 5.4 and 2,3 %, sudangrass hay at 3.06 and 1.6 %. The gobies of the experimental groups exceeded the control one in the consumption of the main nutrients of the rations, with the exception of raw fat. Nutrient digestibility coefficients of the rations were greatest among the bulls of the experimental group II. In the average daily gain in live weight, the gobies of the II experimental group were ahead of control by 10.1 %. According to the data obtained during the experiment, the use in the diet of young animals led to an extreme product with highly dispersed components, providing high quality nutrients and feed, which also positively affect the dynamics of body weight and the intensity of their growth. Thus, the fact revealed by us of a significant increase in the growth of bulls II of the experimental group receiving extruded food with the addition of highly dispersed metal particles proves the enormous role of the usefulness of feeding animals and its influence on the growth and development of a living organism, which makes it relevant to use these feed additives cattle.
