 Abstract. In order to meet high energy needs, fats are usually included in the [1]formula of diets, since their calorie content is significantly higher than that of carbohydrates and proteins. However, due to objective reasons, such as the complexity of digestion, age-related features of the gastrointestinal tract, the use of fat in the diet is limited, and high doses are ineffective. It is possible to increase the amount of digestible fats without increasing the dose by introducing them into the diet using emulsifying additives. The aim of the study was to evaluate the effectiveness of the use of the exogenous emulsifier "Lesimax Premium" at a dose of 0.05%, its effect on productivity and the profile of lipid fractions in the blood of broiler chickens. The maximum gains in live weight are observed: in the period from 28 to 35 days in the experimental group, the difference was 54.5% compared to the control. By the end of the experimental period (42 days), the difference between the groups was 14%. The lowest feed costs were observed in broilers of the experimental group. Thus, the difference with the control was 3.6%. The pre-slaughter live weight of chickens - broilers of the experimental group is higher than the control ones by 8.7% (Р≤0,05). At the same time, the weight of muscle tissue of the experimental group was higher by 15.4% (Р≤0,05) compared to the control group. Emulsifier feeding affected serum levels of cholesterol, triglycerides, and low-density lipoprotein LDL. Thus, the concentration of cholesterol is reduced by 0.71 mmol/l, in relation to the control. Triglycerides of the blood serum of the experimental group are within the control values. There is a decrease in LDL in the experimental group by 0.3 mmol/l relative to the control group. Thus, the results of this study indicate that the addition of 0.05% Lesimax Premium emulsifier reduces feed intake, while providing a good productive effect.
