Problems solved by technology

However, due to the high temperature required for quail breeding, if artificial heating is used to solve the low temperature problem in winter, it will greatly increase production costs and carbon emissions. For this reason, some production companies use antibiotics in feed to prevent diseases and ensure production. Antibiotics find their way into quail products and through the food chain into humans

Embodiment 1

[0025] Example 1 An anti-cold stress nutritional preparation for quail, prepared by the following method:

[0026] (1) Preparation of wheat hydrolyzed protein: put 9~10wt% gluten powder suspension solution in the enzyme reactor, heat to 50°C, adjust the pH to 8.0~8.3 with 1mol / L sodium hydroxide solution, and then press The ratio of enzyme to protein is 1:100 (mass ratio), add alkaline protease, drop sodium hydroxide solution during the reaction to stabilize the pH at 8.0~8.3, react for 2.5~3 hours, add HCl solution to adjust the pH to 7.0, Hydrolyze with 0.2~0.3% (mass percentage) flavor enzyme for 1.5~2 hours, heat the reaction solution to boiling and keep it for 5~10 minutes to inactivate the enzyme, cool to 25~30°C, then centrifuge at 2000 rpm for 10 minutes, and The supernatant is spray-dried to obtain the wheat hydrolyzed protein. Wheat protein hydrolyzate is also commercially available.

[0027] (2) Preparation of chickpea protein peptide: 8~10wt% chickpea protein pow...

Abstract

The invention belongs to the technical field of animal nutrition and in particular relates to an anti-cold-stress nutritional preparation for quails. The preparation is prepared from the following raw materials by weight parts: 60-75 parts of hydrolyzed wheat protein, 15-30 parts of chickpea protein peptide, 0.8-1.0 part of vitamin C, 0.1-0.2 part of a sodium selenite premix containing 1wt% of selenium, 0.8-1.1 parts of a flow agent, 4-6 parts of maltodextrin and 2-4 parts of corn starch. The preparation has an important effect on solving current situations of poor cold resistance of the quails and low house temperature in winter during production of the quails, the physiological status of the quails in a stressful situation can be improved, the disease resistance of the quails is improved, the nutrient absorption speed of the quails is increased, the protein synthesis is promoted, the production performance of the quails is improved, and the feed utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a quail anti-cold stress nutritional preparation. Background technique [0002] Quail products are favored by consumers due to their beautiful flavor and rich nutrition. Quails rank third in my country's poultry breeding volume, and my country's quail breeding volume accounts for one-fifth of the world's. It is the world's largest quail breeding country . Quail is a kind of poultry that loves temperature and is afraid of cold. The domestic quail breeding industry is mainly concentrated in East China and Central China. huge loss. Thereby, guaranteeing the health and production of quail in the cold season has just become the problem that needs to be solved urgently in quail production. However, due to the high temperature required for quail breeding, if artificial heating is used to solve the low temperature problem in winter, it will greatly increase product...
