Rational use of new varieties of forage crops in the production of compound feed for cattle

The article presents the results of research on the use of new varieties of domestic forage crops: sorghum “Kazakhstan 20”, mogar “KazNIIZIR 80” in the production of mixed fodder. Analysis of literary sources shows that there is little information on the use of domestic varieties of sorghum in the production of mixed fodder, there is no information on the use of mogar in the production of mixed fodder in animal feeding. The results of the study show that sorghum varieties are being cultivated in the country. It is established that the mineral and amino acid composition of sorghum is similar to that of corn and barley, which are widely used in the production of mixed fodder. The study of physical and technological properties of grain crops: mogar and sorghum showed that grain crops have good friability. Chemical, amino acid and mineral composition of grain crops were determined. The results of the analysis showed that the protein content of sorghum grain compared to corn is higher by 21.22%, fat content by 5.5%, and fiber content is higher by 1.5 times. The protein content of sorghum grain is 22.8% higher than that of mogar, while the fat content is 1.53% greater. Conversely, the fiber content of mogar grain is 1.38 times higher than that of sorghum. The analysis of amino acid composition in grain crops revealed that mogar has a more valuable profile compared to sorghum, containing 4.62 times more lysine, 2.05 times more methionine, and 1.53 times more threonine. Research results indicate that when using domestic forage crops such as sorghum "Kazakhstan 20" and mogar "KazNIIZiR 80" for feeding young birds and animals, it is necessary to apply moisture-heat treatment.
