Problems solved by technology

However, increasing dietary protein levels is not always beneficial, and excess nitrogen is excreted with urine as urea
Energy is required to metabolize and excrete excess dietary N, resulting in additional metabolized N that increases the body's heat load and reduces dietary N utilization

Abstract

The invention discloses animal feed which comprises the following components in parts by weight: 30-60 parts of ensilage, 10-25 parts of carrot, 3-20 parts of alkali grass, 5-20 parts of corn, 1-10 parts of acidified corn, 1-10 parts of wheat bran, 1-10 parts of wheat middling, 0.1-1 part of salt, 1-8 parts of extruded soybean, 1-8 parts of bean pulp, 1-8 parts of cottonseed cake, 0.1-0.8 part of bone meal, 0.1-1 part of fish meal, 1-10 parts of mineral premix, 0.1-0.5 part of microecologics and 0.1-1 part of rumen by-pass amino acid. The feed formula is reasonably matched, the rumen environment of the dairy cattle is regulated, the nutritive value of various components in the feed is fully exerted, the beneficial effects of improving the feed utilization rate, regulating the rumen function of the dairy cattle, improving the total milk production and lactoprotein content of dairy cows and relieving heat stress of cows are achieved, the animal feed is suitable for developing green and healthy cultivation, and pollution-free ruminant products are produced.

Description

technical field [0001] The invention relates to the field of feed, in particular, the invention relates to a dairy cow feed containing probiotics for feeding, acidified corn and rumen-passed amino acids. Background technique [0002] At present, the dairy industry is becoming one of the fastest growing industries in my country's animal husbandry. Summer heat stress has a negative impact on the dairy industry, and the milk production of dairy cows has dropped sharply. Therefore, it is necessary to maintain high levels of dietary protein in order to maintain milk production under heat stress conditions. However, increasing dietary protein levels is not always beneficial, and excess nitrogen is excreted with urine in the form of urea. Energy is required to metabolize and excrete excess dietary N, resulting in additional metabolized N, which in turn increases the body's heat load and reduces dietary N utilization. [0003] Dairy cows, like other ruminants, have two basic need...
