Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of meat rabbit breeding feed, and particularly relates to a digestion-promoting feed additive for meat rabbit breeding and a preparation method. BACKGROUND

[0002] Livestock breeding provides people with rich meat sources, and livestock breeding generally uses prepared feed for feeding. With the increase of population and the improvement of living standards, the demand for animal protein is increasing, thereby leading to the continuous expansion of the scale of the breeding industry. In order to control the intestinal diseases of livestock and poultry and improve the production efficiency, a large amount of antibiotics are added in the feed. Due to the addition of antibiotics in the feed, the content of antibiotic residues in livestock meat is easy to exceed the standard. The feed with added antibiotics used in the livestock industry will cause serious harm to the safety of livestock products and human health. Therefore, finding new antibiotic substitutes, improving the immunity of animals, increasing the disease resistance of animals, and reducing the harm of residual antibiotics to human health have become one of the most urgent problems to be solved in the livestock breeding industry.

[0003] Meat rabbits are herbivorous animals, and have unique qualities such as strong adaptability, good reproductive performance, fast growth and development, high slaughter rate, tender meat, delicious flavor and rich nutrition. Therefore, meat rabbits are bred in many places. During a long feeding process, meat rabbits are prone to cause intestinal diseases, and common diseases include intestinal discomfort, dysentery, and reduced feed intake, which not only affects the yield of meat, but also affects the quality of meat. The intestinal tract is the largest part of the digestive absorption of nutrients and the largest immune tissue of the body, and plays an important role in maintaining health and promoting growth. Since the digestive system of rabbits is very fragile, it is easy to cause diarrhea and death. Most of the dead rabbits have diarrhea symptoms, which brings huge economic losses to meat rabbit breeders. Therefore, in order to improve the feed intake of meat rabbits, it is necessary to provide a feed additive with good digestion-promoting effect, so as to avoid intestinal discomfort, dysentery and reduced feed intake. SUMMARY
