Plant feed for improving heat stress resistance of calf and feeding method

Abstract

The invention discloses a plant feed for improving heat stress resistance of calves and a feeding method. The plant feed comprises Allium mongolicum, soybean meal, wheat bran, corn, alfalfa and oat. During feeding, fresh Allium mongolicum is cut into segments, and the segments are mixed with concentrated feed corn, wheat bran and soybean meal. The alfalfa and the oat are fed in the morning and at night every day, and the daily feed intake of the alfalfa and the daily feed intake of the oat are 25-35% and 25-35% respectively according to the dry matter feed intake weight; dry substances including, by weight, 15%-20% of corn, 12%-16% of bran and 8%-12% of soybean meal are used as concentrated feed to attract and feed the Allium mongolicum sections at noon, the daily addition level of the Allium mongolicum is 300-800 mg / kg BW, and the Allium mongolicum freely drinks water. According to the invention, the plant feed additive is adopted, and the antioxidant capacity of the body is improved by changing the indexes such as glutathione peroxidase activity, superoxide dismutase and malonaldehyde concentration, total antioxidant capacity and the like in calf blood, so that the heat stress damage of the calf is reduced; meanwhile, potential safety hazards caused by additives such as trace elements and antibiotics to animal products are avoided.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a plant feed and a feeding method for improving heat stress resistance of calves. Background technique [0002] Stress is the body's nonspecific response to various external or internal stimuli, which can cause tissue damage or even disease. With the scale and intensification of animal husbandry, animals are stimulated by transportation, crowding, changes in life patterns, cold and heat, fright, etc., causing animals to passively adapt to the new environment. The clinical symptoms such as decreased amount and weak chewing can lead to the occurrence of various diseases. These diseases not only cause huge losses to farmers, but also seriously affect the quality of meat and dairy products. At present, the animal's anti-stress ability is mainly improved by adding additives to animal diets, thereby improving animal health and productivity. In order to improve the he...

Problems solved by technology

In order to improve the heat stress resistance of animals, additives such as trace elements and antibiotics are usually added to the diet, but excessive amounts of these additives cannot be completely metabolized, which brings great hidden dangers to the ecological environment and food safety
