Description

Technical Field

[0001] The invention relates to the technical field of dairy cow breeding, in particular to a breeding method for improving the milk yield of dairy cows in the periparturient period. Background Art

[0002] The peripartum period of dairy cows refers to a special production stage of about 35 days before and after calving. Cows consume a lot of physical strength and energy during the delivery process, and their bodies are relatively weak after delivery. At the same time, cows begin to lactate, and their demand for nutrients increases sharply. If the nutrient supply is insufficient, cows will use body fat to meet milk production needs, which will in turn cause metabolic diseases such as ketosis and fatty liver.

[0003] The way to provide nutrients to dairy cows is usually to add the required nutritional agents to the feed raised by dairy cows, such as amino acids, fatty acid calcium, vitamins and other chemical nutritional agents. Cow feed is made by crushing grains, silage, straw, etc. into powder. When feeding, it is added to the mixing barrel in a certain proportion and fully stirred and mixed to meet the nutritional needs of dairy cows. Nutritional agents are also added to the feed during the peripartum period.

[0004] Since the feed is relatively dry, the dosage of nutritional agents added to the feed should not be too much, otherwise the nutritional agents will not be fully mixed with the feed. When adding feed to multiple dairy cows, the nutritional agents fed to each cow will be different, resulting in a decrease in the milk production of the cows. Therefore, a feeding method is needed to increase the milk production of periparturient dairy cows. Summary of the invention

Then, the liquid inlet pipe 404 connected to the liquid filling port 403 at the top of the annular liquid outlet sleeve can be connected to the nutritional medicine, so that the nutritional medicine enters the interior of the annular liquid storage sleeve 401. The outer surface of the annular liquid storage sleeve 401 is provided with a The liquid outlet 405 is connected with the delivery channel 42 opened inside the delivery rod 41, and then the nutrient solution can be delivered to the liquid outlet head 43 through the delivery rod 41 and flow out. The liquid outlet head 43 extends into the bottom of the mixing tank 2 with the help of the delivery rod 41, and the nutrient solution can be added to the bottom of the feed in the mixing tank 2. The stirring rod 31 stirs the feed to make the feed loose, and the nutrient solution added to the feed can be fully mixed with the feed, so that each cow can eat the nutrient solution fully mixed with the feed, thereby improving the milk production of the cow;

[0054] It should be noted that when the conveying rod 41 rotates with the stirring rod 31, it can also stir the feed to make the nutritional medicine mixed more fully, and the conveying rod 41 rotates in contact with the inner wall of the mixing tank 2, and can scrape off the feed adhering to the inner wall of the mixing tank 2 to make the feed fully mixed.
