Manufacturing Techniques of the Fodder Additive From Thistle Seeds

Abstract

Technological regulations for the production of a complex feed additive for highly productive animals have been developed. Its composition of milk thistle seeds and biologically active substances (probiotic, betaine and vitamin E) is justified. Technological regimes for processing milk thistle seeds, preparing a premix from biologically active substances, methods for preparing and mixing components, and controlling the quality of products have been worked out on the serial equipment of the feed shop (crusher, mobile conveyor, Doza feed unit). The technological line for the preparation of raw materials and the production of feed additives was developed using the principle of cyclic-periodic operation of the equipment available in the feed shop. An experimental sample of the feed additive was made with the following composition, in % by weight: milk thistle seed -92.76; probiotic "Profort" - 6.00; betaine hydrochloride (97%) - 1.20; vitamin E (50%) - 0.04 (the activity of the drug is indicated in brackets). The use of this feed additive in the diet of highly productive dry cows in the amount of 0.4 kg per day per head increases the milk productivity of animals by 4.3%. The use of the feed agent contributed to a reduction in the time for separation of the placenta compared with control animals by 2.4 hours. Animals from the group that received the supplement with feed were characterized by better reproductive ability. After 44 days they were inseminated after calving, from the control group were inseminated after 79 days, or 35 days later. An additive from milk thistle seeds and biologically active substances can be made on farms using existing equipment.
