Natural biologically active additive in feeding calves

Studies on the effectiveness of inclusion sodium humate in diet young cattle were conducted four groups animals. Installed improvement consumption hay by bulls experimental 12.5–20 % compared with control was found, as a result which they consumed more feed units 1.5, 2.3, and 3.5 %, exchange energy – 2.4, 3.9 5.1 digestible protein 1.2, 2.1 3.7 %. As part KR-2 compound feed, amount hemoglobin blood animals II group increased 5.8 III 6.8, IV 7.8 to analogs. With growth calves blood, bactericidal activity serum 1.3, 1.9, 2.5 lysozyme 0.1 0.2, 0.3 indicates an increase natural resistance whose diets injected studied peat sapropel preparation. The use composition has positive effect consumption, physiological condition, animals, provides average daily live weight 3.2–9.4 while reducing cost its production 2.9–8.5 percent.
