Use of grass meal in compound feed for rainbow trout and sturgeon
Abstract
The article considers the results of the study of grass meal from binary mixtures of chumiza, vetch, pea, sudan grass, mogar in various combinations and their use in the composition of compound feed for fish. The chemical composition of the green mass of chumiza, soybeans and vetch were studied. It was found that both in pure form and in the form of binary mixtures, the green mass of the studied crops contains crude protein from 13.0 to 21.0 %, crude fat from 1.9 to 2.4 %, crude fiber from 34.0 to 37.0 %. Grass meal also contains carotenoids, macro- and microelements that are part of the enzymes of the fish body and thereby accelerate the growth processes of fish and reduce feed coefficients. It has been established that grass meal in the amount of 1.0 % from a mixture of sudan grass and soybeans, chumiza and peas, and chumiza and vetch can be used in the composition of compound feed for rainbow trout and sturgeon fish.
