The invention discloses a breeding method of cows. Excellent young cows are selected from 70-day-old calf herds of generations obtained after Changbai bulls and Dahe black cows are hybridized to be stocked as reserve cows, according to the physiological properties and nutritional requirement characteristics of the reserve cows at all stages, the reserve cows are bred according to the four stages,daily rations are prepared from special feedstuff and Chinese herbal medicine additives specifically at all the stages, growth, development, oestrus and ovulation of the reserve cows are promoted, a free feeding mode and a limited feeding mode are adopted, and optimal hybridization signs of the reserve cows are obtained; reserve cow herds are screened and optimized three times at the breeding stage, and the cows with the growth and development and immune antibodies not meeting seed standards are eliminated. According to the reserve cows bred through the method, the seed percent of pass reaches90%, the conception rate of primiparous cows reaches 90%, the seed percent of pass and the conception rate are increased by 4-5 percents compared with those of a common breeding method, the number oflive births is increased by almost one, and good economic benefits and social benefits are achieved.
