1. The digestive physiological structures of horses and cattle are essentially different, so the requirements for feed will be different. Horses are monogastric animals, while cows are compound stomach animals. Monogastric animals can make full use of concentrated feed, while compound stomach animals can't. Excessive gastric acidosis will occur, so the diet of dairy cows must ensure the supply of roughage. A horse fed with concentrated feed for a short time can quickly recover its physical strength. Cattle can make full use of silage and ammoniated feed because of rumen microorganisms, while horses can only make small use of silage. Eating too much will destroy the oral digestive system, but ammoniated feed is not edible.

Horses are speed type, while cows are endurance type. So horses have developed limbs and are suitable for running. In ancient times, horses were the main driving force of agricultural production, transportation and military activities. With the development of productive forces, the improvement of science and technology, the invention and wide application of power machinery, the role of horses in real life is becoming less and less. Horses are mainly used for equestrian sports, scenic experience and milk and meat production, and the feeding quantity is greatly reduced. However, in some developing countries and regions, horses are still mainly used for service and are an important source of service strength. The horse's staple food is grass.

3. Cattle are mammals and herbivores, and some species are domestic animals (including domestic cattle, yellow cattle, buffaloes and yaks). The body is stout, and some bull heads have diagonal lines. Cattle also have many uses: meat and milk can be eaten, cowhide can be used as industrial raw materials and clothing, and horn can be used as medicinal materials and handicrafts; Cattle can also provide labor for agricultural production.
