Determination of influence of combined feed with carnitine and 3% lipids on digestibility of nutrients in ration of fattening stores was realized in the conditions of the Republic of Belarus by an example of 8 castrated male pigs of Belarusian meaty breed with body weight of 60-65 kg. Piglets were divided into 2 groups in accordance with analogue pair principle. Selected animals were kept in single cages specially equipped for fecal and urina gathering. Both groups of animals were given the same combined feed SK-26 which included 3% lipids. Experimental piglets were fed with combined feed with carnitine in dose of 50 g/t of mixed fodder. The mixed fodder contained the following ingredients: wheat; triticale; grain mixture; sunflower oil cakes; liprot SG; tricalcium phosphate; calcium carbonate; salt; premix KS-4; vegetable oil. Research results showed that enriching of combined feed carnitine rendered positive influence on digestibility and absorbency of nutrients. It made it possible to increase the digestibility of dry matter on 2,1%, organic matter on 2,0%, crude protein on 3,1%, crude fat on 7,4%, crude fiber on 8,6%, free-nitrogen extract on 1,1%, as well as to increase nitrogen, calcium and phosphorus absorbency. Quantity of saved nitrogen in the experimental group (with carnitine additive) was on 21,1% than in control one. Quantity of saved nitrogen and absorbed with feed was on 9,8% and 5,6% respectively higher than the same indexes for the control group; calcium - on 15,5% and 2,6%, phosphorus - on 23,3% and 3,7%, respectively
