OPTIMIZATION OF PRESSING IN THE TECHNOLOGY OF MANUFACTURING PHYTO-MINERAL-SALT BRIQUETTES FOR CATTLE

Abstract

The purpose of the study: to determine the optimal pressing in the technology of manufacturing phyto-mineral-salt briquettes for cattle. The study of the technology of creating phytomineral salt briquettes showed that pressing at a pressure of 40 MPa is optimal in the process of their manufacture, at which the briquettes acquire a density of 1,763±0.146 g/cm3 and a strength of 6.68± 0.56 MPa.   During long-term storage, the density and strength of phyto-mineral-salt briquettes change slightly. However, this does not reduce their attractiveness in animals and, consequently, their licking ability. The obtained photos of mineral-salt briquettes, consisting of feed salt with the addition of trace elements and needles of Siberian fir, are a feed additive useful for the body of cows in the form of briquettes.
