Flaxseed cake, a by-product of oil extraction, obtained after the extraction of oil from flaxseed. In animal diets, it can be used as an alternative to sunflower meal or meal, as well as flaxseed. Characteristics: 25% digestible protein < li> 30% nitrogen-free extractives. 1kg of flaxseed meal contains 338g of crude protein, 102g of crude fat, 11.5g of lysine and 9.1g of methionine. Flaxseed meal contains all the necessary micro and macroelements, vitamins A, D, E, but vitamin B is most fully represented. In terms of digestible protein, flaxseed meal is 2.7 times higher than wheat, 5 times in fat content, and 4.2 times in calcium content , for iron by 5 times. According to the doctor of agricultural sciences, professor, member of the Russian Academy of Agricultural Sciences VV Glukhov, flaxseed cake is a valuable, high-calorie, concentrated feed for agricultural animals. Studies of the Research Institute of Animal Husbandry and Veterinary Medicine have shown that the use of flaxseed cake in an amount of 0.5-0.8 kg per head per day with coarse-concentrate diets increases the milk productivity of cows by 5-12%, which corresponds to 1.5-2 liters of milk . Flaxseed cake has shown very high efficiency in fattening young animals - it accelerates growth, significantly improves the condition of wool and hooves. (Flaxseed cake is given to agricultural animals of all types in dry or wetted form in a mixture with other feeds and as part of compound feeds). Recommended norms: Milking cows can be given up to 4 kg per day (when processing milk for butter up to 2.5 kg); Calves - up to 10 months - up to 500g in feed mixture, has a very good effect on growth (weight, hair, eyes, hooves); Fattening young cattle - 1.5 kg, Horses - the optimal rate of 0.5-1 kg per day, maximum - 2 kg without work and 3.5 kg for horses in training; Pigs - 200-300 g per head per day and 400-600 g for pregnant and suckling queens are introduced into the diet of fattening pigs. For lambs - when fattening lambs, the norm is up to 4 months 100 g, over - 200 g per day. For adult poultry - 7%, for young animals - 2%, of the total volume of dry feed.
