Preparation and application of premixed feed for raccoon dogs in breeding period

Abstract

The invention provides preparation and application methods of a premixed feed for raccoon dogs in breeding period, and belong to the technical filed of feeds. The invention especially relates to preparation and application methods of a premixed feed for improving performances of raccoon dogs in breeding period. The premixed feed for the raccoon dogs in the breeding period is beneficial for increasing element absorption, and decomposed yeast is capable of effectively improving digestion and utilization rates of nutrients in the feed; the premixed feed is capable of effectively improving digestion rates of the raccoon dogs in the breeding period to the nutrients in the feed, improving intestinal immunity, and improving feed utilization rate; the premixed feed is beneficial for digestion and utilization of the nutrients, as well as preventing reduction of breeding and growth performances of the raccoon dogs in the breeding period caused by diarrhea and reducing the risks of viral infection of the raccoon dogs. The ingredients in the premixed feed are capable of effectively improving breeding performance, immunity and feed utilization rate of the raccoon dogs in the breeding period, reducing intestinal diseases, including diarrhea and the like, of the raccoon dogs in the breeding period, and improving animal disease resistance and immunity. Moreover, the premixed feed is capable of improving economic benefits of artificial breeding, as well as reducing drug residues and heavy metal content in the carcass.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a premixed feed for improving the reproductive performance and feed utilization rate of raccoon dogs and a preparation method thereof. Background technique [0002] Raccoon fur is one of the main varieties of fur. Due to the broad market prospect, the breeding of raccoon dog has formed a large-scale industry in China in the past 30 years. At present, China is the country with the largest number of raccoon dogs in the world. With the improvement of people's living standards, the demand for high-grade fur products is also increasing, and the scale of raccoon dog breeding is also expanding. The female raccoon dog during the breeding period is the management core of the large-scale and intensive breeding production of raccoon dogs. During this period, the female raccoon dog not only needs sufficient nutrition to meet its own maintenance needs, but also must meet the needs ...

AI Technical Summary

Problems solved by technology

This product provides suitable vitamins, mineral levels and trace element concentrations needed by raccoon dogs during the breeding season. 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 Yeast iron, yeast manganese, yeast copper, yeast selenium and yeast chromium are added. While it is beneficial to improve the absorption of elements, the decomposed yeast can effectively improve the digestion and utilization of nutrients in the feed; this product adds protease, lipase and A compound enzyme composed of various enzymes such as cellulase, wherein protease accounts for 10% (produced by Aspergillus niger), and its activity is 13000-14000U / g, lipase accounts for 9% (produced by 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 accounts 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 The activity is 1200-1300U / g, phytase accounts for 16% (produced by Aspergillus niger), and its activity is 2100-2200U / g. The above enzymes solve the raccoon dog in the breeding season, the nutritional level is relatively low, and the nutrients in the feed raw materials are digested Low rate, insufficient secretion of digestive tract enzymes, etc., effectively improve the digestibility of nutrients in the feed for raccoon dogs during the breeding period; probiotics are added to this product, of which Bacillus licheniformis accounts for 22% and Bacillus subtilis 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 raccoon dogs during the breeding season, improve intestinal immunity, and improve feed utilization; this product adds Chinese herbal medicine ingredients, of which hawthorn accounted for 20%, tangerine peel 10%, dandelion 13%, Artemisia argyi 12%, Artemisia annua 10%, Radix Radix 10%, Acanthopanax 25%, hawthorn and tangerine peel in Chinese herbal medicine have promoting Digestion 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 breeding season and reduce reproductive performance. Artemisia annua and Radix Radix have antiviral effects, which can reduce raccoon dogs from being infected by viruses. 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%. Increase food intake and improve reproductive performance; this product also adds methionine, lysine, threonine and arginine, the main limiting amino acids of raccoon dogs
