Using a natural origin feed additive in sport horses diets

The purpose of the study is the effect of the feed additive Laminaria with a natural component on the body of horses. Tasks: to study the feeding of horses with the feed additive Laminaria, the physiological state of horses; to determine the economic efficiency of using the feed additive Laminaria. The study was carried out in the equestrian center (ESC) of the State Agrarian University of the Northern Trans-Urals. It has been established that in the diet of horses there is an insufficient amount of vitamins and minerals, especially trace elements. Two groups of horses were formed by the method of pair-analogues, aged from 15 to 24 years - control and experimental. The horses of the control group received the main diet, consisting of the following ingredients: oats - 1.5 kg; wheat bran - 0.5; hay - 12; porridge (steamed oats + bran) - 0.5 kg, - and a household feed additive identical to the test one, in the amount of 25 g. The introduction of the feed additive Laminaria in the amount of 20 g per head per day provided the diet with the necessary vitamins and minerals (the composition of the supplement: vitamins A, C, D, E, B1, B2, B12, pantothenic and folic acids; iodine (up to 3 % ), bromine, manganese, cobalt, zinc, magnesium, iron, potassium, sodium, sulfur, phosphorus, nitrogen; kelp polysaccharides (up to 21 %), alginic acid and its salts (up to 25 %); L-fructose (up to 4 %); protein substances (up to 9 %)). By the end of the experiment, after 30 days, the physiological state of the horses of the experimental group visually improved - molting began to pass faster and less intensively, the hoof horn became harder and better trimmed, dandruff formation became less noticeable. Skin irritation and inflammation with excessive sweating was no longer observed. In the horses of the experimental group, an increase in hemoglobin to the physiological norm was noted. The parameters of the general blood test were within the physiological norm. The cost of feed, taking into account the Laminaria feed additive, decreased by 480 rubles per animal per day.
