Preparation and application of premixed feed for raccoon dog in winter hair period

Abstract

The invention provides preparation and application of premixed feed for a raccoon dog in a winter hair period, belongs to the technical field of feed, and particularly relates to a method for increasing the utilization rate of the feed for the raccoon dog in the winter hair period. According to physiological digestive characteristics of the raccoon dog and production practice research data, with the goal of improving the growth performance, the immunity, the feed utilization rate and the fur quality of the raccoon dog, the digestive rate of the raccoon dog in the winter hair period for nutrient substances in the feed is effectively increased, digestion and utilization of the nutrient substances are facilitated, dandelion herbs and argy wormwood leaves have the functions of diminishing inflammation and preventing diarrhea, reduction of the growth performance due to diarrhea of the raccoon dog in the winter hair period can be prevented, food consumption of the raccoon dog can be effectively increased, production performance is improved, the anti-virus capability and immunity of animals are enhanced, the economic benefit of artificial raccoon dog breeding is improved, and drug residues and heavy metal content in a carcass are reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, and particularly relates to a premixed feed and a preparation method for improving the feed utilization rate, immunity and fur quality of raccoon dogs in the winter fur season. [0002] technical background [0003] Raccoon dog is a precious fur animal in my country. Its fur is thick, soft, light, beautiful, tough and wear-resistant. It is one of the most popular high-grade fur raw materials in the fur market at home and abroad. After the raccoon dog enters the winter hair growth period, the best period of body growth and development has passed. At this time, the body weight and bone growth rate of the raccoon dog are relatively slow. The winter hair growth period of the raccoon dog is mainly the storage of subcutaneous fat and the growth of coat and skin Some essential nutrients in the diet are directly related to the final fur quality of raccoon dogs, and play a key role in the economic benefits of...

Problems solved by technology

This product provides the appropriate vitamins, mineral levels and trace element concentrations needed by raccoon dogs in the winter fur period. Calcium and phosphorus are mainly supplemented through bone meal, which is more conducive to the absorption of raccoons; iron, manganese, copper, selenium and chromium are supplemented mainly through Yeast iron, yeast manganese, yeast copper, yeast selenium and yeast chromium are added to help improve the absorption of elements, and the decomposed yeast can effectively improve the digestion and utilization of nutrients in the feed; this product adds protease and lipase A complex enzyme composed of various enzymes such as cellulase, wherein protease accounts for 10% (produced from Aspergillus niger), and its activity is 13000-14000U / g, lipase accounts for 9% (produced from Aspergillus niger), and its activity is 6500 -7000U / g, pectinase accounts for 7% (produced from Aspergillus niger), its activity is 800-900U / g, amylase accounts for 11% (produced from Aspergillus niger), its activity is 600-700U / g, cellulase Accounting for 12% (produced from Aspergillus niger), its activity is 2100-2200U / g, hemicellulase accounts for 11%, its activity is 1900-2000U / g, glucanase accounts for 24% (produced from Aspergillus niger), Its activity is 1200-1300U / g, phytase accounts for 16% (produced by Aspergillus niger), and its activity is 2100-2200U / g. The above enzymes can solve the problem of raccoon dogs in the winter fur period, and the nutritional level is relatively low. Problems such as low material digestibility and insufficient secretion of digestive tract enzymes have effectively improved the digestibility of nutrients in the feed for raccoon dogs in the winter fur period; probiotics are added to this product, of which Bacillus licheniformis accounts for 22%, and Bacillus subtilis Bacillus accounts for 15%, Enterococcus faecalis accounts for 18%, Enterobacter faecium accounts for 18%, and Bifidobacteria accounts for 27%. Probiotics can improve the intestinal environment of winter-haired raccoon dogs, improve intestinal immunity, and improve feed utilization; This product is added with Chinese herbal ingredients, among which hawthorn accounts for 20%, tangerine peel accounts for 10%, dandelion accounts for 13%, mugwort leaves account for 12%, artemisia annua accounts for 10%, isatidis accounts for 10%, eleuthero 25%, Chinese herbal medicine hawthorn Tangerine peel and tangerine peel have the function of promoting digestion, which is beneficial to the digestion and utilization of nutrients. Dandelion and mugwort have anti-inflammatory and anti-diarrhea effects, which can prevent diarrhea in the winter-haired raccoon dog and reduce growth performance. The risk of virus infection, Acanthopanax has the effect of improving immunity; flavoring agents are added to this product, of which fishy smell accounts for 40%, sweeteners account for 30%, and flavoring agents account for 30%. Flavoring agents can effectively improve the immunity of raccoon dogs Feed intake, improve production performance; this product also added methionine, lysine, threonine and arginine, the main limiting amino acids of raccoon dogs
