preparation example Construction

[0046] The invention also discloses a method for preparing feed for improving milk production and hoof shell hardness of dairy cows, which includes the following steps:

[0047] Step 1, preparation of perilla seed extract:

[0048] Step 1.1, pressing the perilla seeds, controlling the pressing temperature at 35-45°C, and pressing to obtain perilla seed oil and perilla seed meal;

[0049] Step 1.2, pulverizing the perilla seed meal with a pulverizer to a fineness of 30-40 mesh to obtain perilla seed meal powder;

[0050] Step 1.3. Take the perilla seed meal powder and mix it evenly with the filler, put it into the material barrel of the extraction kettle, the volume ratio of the perilla seed meal powder to the filler is 1:2, put the material barrel into the supercritical CO 2 In the extraction kettle of the equipment, the pressure of the extraction kettle is controlled at 20-28MPa, and the temperature is controlled at 37-45°C;

[0051] Step 1.4, perilla seed oil with CO 2 Th...

Embodiment 1

[0059] The feed formula to improve milk production and hoof shell hardness of dairy cows is 550kg of corn per 1000kg of concentrate feed; 30kg of bran; 130kg of soybean meal; 80kg of cotton meal; ; Fatty acid calcium 25kg; Calcium hydrogen phosphate 10kg; Light calcium carbonate 15kg; Calcium bicarbonate 23kg; Magnesium oxide 7kg; Salt 12kg; Seed extract 150g.

[0060] The feed formula is prepared by the following methods:

[0061] Step 1, preparation of perilla seed extract:

[0062] Step 1.1, pressing the perilla seeds, controlling the pressing temperature at 40°C, and pressing to obtain perilla seed oil and perilla seed meal;

[0063] Step 1.2, pulverize the perilla seed meal with a pulverizer, and the crushing fineness is 35 mesh, and obtain the perilla seed meal powder;

[0064] Step 1.3. Take the perilla seed meal powder and mix it evenly with the filler, put it into the material barrel of the extraction kettle, the volume ratio of the perilla seed meal powder to the ...

Embodiment 2

[0073] The feed formula to improve milk production and hoof shell hardness of dairy cows is that every 1000kg of concentrate feed contains 550kg of corn; 30kg of bran; 130kg of soybean meal; 80kg of cotton meal; 90kg of imported distiller's grains and its solubles; 10kg; light calcium carbonate 15kg; calcium bicarbonate 23kg; magnesium oxide 7kg; salt 12kg; dairy cow lactation premix 25kg; The preparation method of this feed is with embodiment 1.

Abstract

The invention discloses a feed for increasing milking yield of dairy cows and hardness of hoof shells and a preparation method thereof. The feed is prepared from the following components in parts by mass: 540 to 560 parts of corn, 28 to 32 parts of bran, 24 to 26 parts of fatty acid calcium, 100 to 140 parts of soybean meal, 70 to 90 parts of cottonseed meal, 80 to 100 parts of distiller's dried grain and soluble matter thereof, 8 to 12 parts of calcium hydrophosphate, 14 to 16 parts of light calcium carbonate, 21 to 25 parts of calcium bicarbonate, 6 to 8 parts of magnesium oxide, 11 to 13 parts of edible salt, 24 to 26 parts of premixer in lactation period of the dairy cows, 1 to 2 parts of Proceatin, and 2 to 3 parts of ConditionAde, wherein the total part by mass is 1000 parts; the feed also comprises 30 to 300g / kg of fructus perillae extract in total parts of the components by mass. After the feed is fed to the dairy cow, the milking yield is increased, the hardness of the hoof shells is improved, and the immunity of the dairy cow is enhanced.

Description

technical field [0001] The application belongs to the field of feed processing, and in particular relates to a feed for improving the milk yield and hoof shell hardness of dairy cows and a preparation method thereof. Background technique [0002] There are many causes of limb and foot disease, such as genetic factors, environmental factors, nutritional factors and so on. Leg and hoof disease of dairy cows is a general term for a series of diseases that cause lesions on the limbs and hooves of dairy cows, among which hoof diseases can account for 88%. The common and harmful ones in production include: laminitis, sole abscess or ulcer, white line crack, foot rot, etc. Second only to mastitis, dairy cow limb and hoof disease has risen to become the second major disease affecting the development of the dairy industry in recent years. In the UK, nearly 60% of dairy cows suffer from foot disease; in the United States, 73% of dairy cows are reported to have foot disease; the prop...
