Influence of natural mineral additive on digestibility of nutrients in lactating cows

Abstract

TThe article presents the results of the experiment on the application of the mineral additive with A, D, E vitamins in the diets of lactating cows at the same level of the exchange energy. The complex mineral additive consisted of smectite tripoli with Si, Ti, Al, Fe, Mn, Ca, Mg, Na, K, P elements and A, D, E vitamins, the additive was prepared at LLC "AIP-Phosphates”. The diet of the lactating cows included 300 g of the mineral additive per animal per day. The milk yield in the test group during the experiment increased by 136.8 kg (10.67%) in comparison with the control group. Against the background of the scientific and economic experience, there was conducted a study on digestibility of nutrients and the use of calcium and phosphorus in lactating cows. The analysis of digestibility coefficients of the main nutrients after application of the mineral additive via feed showed that, the additive had been the most effective in the digestibility of crude fiber and fat in the gastrointestinal tract. The exertion of calcium via milk in the test group increased by 11% and phosphorus - by 9.15%.
