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] (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.

[0026] (2) Preparation of chickpea protein peptide: 8~10wt% chickpea protein powder (commercially available, or prepared from chickpea according to the conventional protein powder preparati...

Embodiment 2

[0032] (1) Effect of the preparation of the present invention on physiological and biochemical indicators related to cold stress in quail in a cold environment

[0033]Experimental design: 600 30-day-old healthy Difak quails were selected and randomly divided into 6 groups, namely group 0 (non-cold stress control group), group 1 (cold stress control group), and groups 2-5 (experimental group), with 100 rats in each group, and 4 replicates, each with 25 rats. The temperature of group 0 was 23°C (suitable temperature), the temperature of group 1~5 was 13°C (in a state of cold stress), and the test time was 18 days; ~5 groups were fed diets containing 1.5%, 2.0%, 3% and 4% (percentage by weight) of the anti-cold stress nutritional preparation (Example 1) of the above scheme 2, the composition and nutritional level of the experimental diets are shown in Table 2 .

Abstract

The invention belongs to the technical field of animal nutrition, and in particular relates to a quail anti-cold stress nutritional preparation. The preparation of the present invention is made of the following raw materials in parts by weight: 60-75 parts of wheat hydrolyzed protein, 15-30 parts of chickpea protein peptide, and vitamin C? 0.8~1.0 parts, 0.1~0.2 parts of sodium selenite premix containing 1wt% selenium, 0.8~1.1 parts of dispersant, 4~6 parts of maltodextrin and 2~4 parts of corn starch. The preparation of the present invention plays an important role in solving the poor cold resistance of quails and the low temperature of houses in winter in quail production, and can also improve the physiological state of quails under stress, improve the disease resistance of quails, and accelerate the absorption of nutrients by quails , Promote protein synthesis, improve quail production performance and feed utilization.

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...
