Preparation and application of premixed feed for raccoon dog in growing period

Abstract

The invention provides preparation and application of premixed feed for a raccoon dog in a growing period, belongs to the technical field of feed, and particularly relates to premixed feed and a preparation method for increasing feed utilization rate and the growth speed and immunity of the raccoon dog in the growing period. According to the premixed feed, the digestive rate of the raccoon dog in the growing period for nutrient substances in the feed is increased, the intestinal environment of the raccoon dog in the growing period can be improved, intestinal immunity is improved, the feed utilization rate is increased, reduction of the growth performance due to diarrhea of the raccoon dog in the growing period can be prevented, the growth speed and immunity of the raccoon dog in the growing period can be effectively improved, intestinal diseases such as the diarrhea of the raccoon dog in the growing period is reduced, 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 in particular relates to a premixed feed and a preparation method for improving the growth rate, immunity and feed utilization rate of raccoon dogs in the breeding period. Background technique [0002] Raccoon dog belongs to carnivorous order, canidae, and raccoon dog. It is one of the important economic animals in my country, and its economic value is mainly reflected in its skin. The breeding of raccoon dogs in my country is mainly concentrated in Jilin, Heilongjiang, Liaoning, Hebei, Shandong and Inner Mongolia, and plays an important role in the development of local rural economy. With the continuous increase of raccoon breeding in my country, feed resources continue to be scarce, and feed costs continue to rise. In order to save costs, some farmers and manufacturers choose low-cost feed materials with low nutrient digestibility, especially if various raccoon dogs are raised. Insufficient su...

AI Technical Summary

Problems solved by technology

This product provides the appropriate vitamins, mineral levels and trace element concentrations required by raccoon dogs during the breeding 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 utilization of nutrients in the feed; this product adds protease, lipase and fiber Sulfase and other compound enzymes, among which protease accounts for 14.5% (produced by Aspergillus niger), its activity is 13000-14000U / g, lipase accounts for 12.5% ​​(produced by Aspergillus niger), its activity is 6500-7000U / g, pectin Enzymes account for 5% (produced from Aspergillus niger), its activity is 800-900U / g, amylase accounts for 10.5% (produced from Aspergillus niger), its activity is 600-700U / g, cellulase accounts for 8.5% (produced from black Aspergillus), its activity is 2100-2200U / g, hemicellulase accounts for 9%, its activity is 1900-2000U / g, glucanase accounts for 20% (produced from Aspergillus niger), and its activity is 1200-1300U / g g, phytase accounts for 20% (produced by Aspergillus niger), and its activity is 2100-2200U / g. The above enzymes solve the problems of imperfect development of the raccoon dog's digestive tract and insufficient enzyme secretion during the breeding period, and effectively improve the growth period. The digestibility of raccoon raccoons to nutrients in the feed; probiotics are added to this product, of which Bacillus licheniformis accounts for 22%, Bacillus subtilis accounts for 23%, Enterococcus faecalis accounts for 15%, Enterobacter faecium accounts for 15%, Bifidobacterium bifidus Bacilli account for 25%, and probiotics can improve the intestinal environment of raccoon dogs during the breeding period, improve intestinal immunity, and improve feed utilization; this product adds Chinese herbal ingredients, of which hawthorn accounts for 20%, tangerine peel accounts for 15%, and dandelion accounts for 20%. %, Artemisia argyi leaves account for 10%, Artemisia annua accounts for 10%, Banlangen accounts for 10%, Acanthopanax accounts for 15%, hawthorn and tangerine peel in Chinese herbal medicine have the effect of promoting digestion, which is beneficial to the digestion and utilization of nutrients, dandelion and Artemisia argyi have anti-inflammatory and anti-inflammatory effects. The effect of diarrhea can prevent the growth performance of raccoon dogs from diarrhea during the breeding period. Artemisia annua and Radix Isatidis have antiviral effects and can reduce the risk of virus infection of raccoon dogs. Acanthopanax has the effect of improving immunity; Fishy aroma accounts for 40%, sweeteners account for 30%, and flavoring agents account for 30%. Flavoring agents can effectively increase the feed intake of raccoon dogs and improve production performance; this product also adds methionine and lysine, the main limiting amino acids of raccoon dogs. acid, threonine and arginine
