Physical and chemical indicators Name of the indicator Norm ND for the product Actual ND indicators for test methods Mass fraction of moisture and volatile substances,% 7 - 10 5.4 GOST 13979.1-68 Crude protein in absolutely dry matter,% 39.0 35.2 GOST 13496.4-93 Mass fraction of crude fiber per dry matter,%, no more than 26.0 11.5 GOST 13496.2-91 Mass fraction of fat extract in dry matter,%, no more than 4.0 4.0 GOST 13496.15-97 Sunflower cake meets the requirements of the DSTU 4638: 2006 standard Pressing is the process of squeezing oil out of oilseeds. The extraction process involves isolating the residual oil content from the seeds after pressing using organic solvents. Moreover, if the cake obtained after pressing contains up to 10% residual oil, then in the meal this percentage is increased to 1.5 - 2%. Meal is indispensable as a high-protein additive in the production of feed for cattle, pigs, and poultry, as it contains natural proteins, fiber, vitamins E and B, potassium, phosphorus and other minerals. Sunflower meal is a valuable feed that contains 30â??43% crude protein, a rich set of amino acids, in particular a high content of methionine, which has a beneficial effect on the growth and development of young animals. Compared to cake, meal contains slightly more crude protein, but less fat - no more than 1.5%. The husk content is no more than 16% (meal is also produced without husk). Sunflower meal is deficient in lysine, but unlike other meals it contains virtually no anti-nutrients. The arabinoxylan index of sunflower meal relative to soybean meal is 117, which ensures high protein digestibility compared to other protein feeds of plant origin (78-80%). The content of vitamin B in sunflower meal is significantly higher than in soybean meal. Sunflower meal is rich in niacin, riboflavin, choline, biotin, pantothenic acid and pyridoxine. In addition to this, sunflower meal is an excellent source of vitamin E. Factors limiting the use of sunflower meal (cake) include chlorogenic and quinic acids, the level of which is 1.56 and 0.48%, respectively, and fiber. The negative effect of high doses of chlorogenic acid is manifested in the inhibition of trypsin and lipase, so its level should not exceed 1%. Including methionine in the diet in addition to the norm prevents the negative effects of excess chlorogenic acid. Areas of application of sunflower meal: It is used for feeding purposes of animals, birds, and fish. It is used in its pure form and also as an additive in animal feed. Contains up to 43% easily digestible protein. Sunflower meal increases animal productivity and improves the quality of livestock products. Increases the fat content in milk and the daily milk yield of cows.
