Abstract: Abstract High-carbohydrate grain (HG) concentrates are used in the diets of weanling foals to meet their high energy requirements for growth and development, but they often cause growth that is too rapid and increase the risk of developmental orthopedic disease such as osteochondritis dissecans and can predispose gastric ulceration. This study evaluated the effect of a grain-free diet on the growth and development of Orlov trotter foals and compared to foals receiving a HG diet. Ten foals (6 colts, 4 fillies) after weaning at 6 months were divided into two equal groups. All foals received mixed grass hay (crude protein (CP)—8.5%, crude fiber (CF)—21.3%) ad libitum and balancer supplement for foals. The HG group (HG) received a standard ration with mixed feed based on micronized grain (ME—11.6 MJ/kg, CP—15%, CF—7.5%, starch + sugar (S)—47%); grain-free group (GF) received pellets consisting of alfa-alfa meal, beet pulp, sunflower meal, flaxseed meal, wheat bran. (ME—11.7 MJ/kg, CP—15%, CF—21%, S—6%). The amount of feed was rationed individually, considering the needs of foals in accordance with the “Norms and rations for feeding farm animals” (Beguchev in Anim Husb 3:14–20, 1965). Foals were measured and blood samples were collected prior to receiving the treatment diets and after 90 days. The indicators of relative growth were considered. Data were analyzed using STATISTICA v.10 (StatSoft.ru). Following the 90-day period, there were no significant differences in any of the measurements or in the relative increase in each parameter (P > 0.05). In both groups, blood indicators were within the normal range, but GF had significantly higher (P
