Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry, and in particular to a healthy milk-producing feed formula for low-production cows. Background Art

[0002] Low-production dairy cow milk feed is a diet designed specifically for the stage of declining milk production (such as late lactation and early dry period). Its core goal shifts from pursuing high production to maintaining body condition, restoring health, ensuring reproduction, and reducing environmental burden.

[0003] During the process of realizing the present invention, the inventors discovered that the existing technology had the following problems: insufficient fiber content in roughage leads to decreased rumen health; low protein utilization and high urea nitrogen emissions cause environmental pollution; excessive pursuit of milk production leads to excessive fatness, affecting reproductive performance; conventional additives do not take into account carbon emission control needs. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a healthy milk-producing feed formula for low-yielding dairy cows, which solves the problems of the existing feed formula, namely, insufficient roughage fiber content, which leads to decreased rumen health; low protein utilization rate, high urea nitrogen emissions causing environmental pollution; excessive pursuit of milk production leading to excessive fatness, affecting reproductive performance; and conventional additives that fail to take into account carbon emission control needs.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a healthy milk-producing feed formula for low-yielding dairy cows, comprising the following components by weight: 280-350 parts of organic whole-plant silage corn; 28-35 parts of soybean meal; 15-22 parts of corn DDGS; 18-25 parts of organic corn flakes; and 5-7 parts of premix;

[0006] The premix contains:

[0007] Fat powder, organic dicalcium phosphate, sodium bicarbonate, organic calcium source, sodium chloride, magnesium oxide, yeast, methionine, lysine;

[0008] Vitamin and trace element complex, organic chromium, yeast selenium, organic zinc, rumen bypass glucose, protease.

[0009] Preferably, the organic calcium source is natural calcium carbonate or calcium citrate, and the added amount is 8-12% of the total weight of the premix.

[0010] Preferably, the soybean meal is processed by a heat treatment process, and the rumen bypass protein ratio is ≥60%.

[0011] Preferably, the amount of protease added is 3-5 g per ton of diet to reduce rumen methane emissions.

[0012] Preferably, the organic chromium is chromium picolinate, and the addition amount is 0.02-0.05% of the total weight of the premix.

[0013] Beneficial effects

[0014] This invention provides a healthy milk-producing feed formula for low-yielding dairy cows. This formula offers the following health benefits: high-fiber silage restores rumen papilla growth; a combination of organic trace elements reduces the incidence of hoof disease; and body condition scores steadily improve, preventing overweight. Milking performance: daily milk yield increases; milk protein content is improved. Environmental and economic benefits: rumen methane emissions are reduced; urea nitrogen excretion is reduced; and daily feed costs per cow are reduced. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] The present invention provides a technical solution: a healthy milk-producing feed formula for low-yielding dairy cows, comprising the following components by weight: 280-350 parts of organic whole-plant silage corn; 28-35 parts of soybean meal; 15-22 parts of corn DDGS; 18-25 parts of organic corn flakes; and 5-7 parts of premix.

[0017] The premix contains:

[0018] Fat powder, organic dicalcium phosphate, sodium bicarbonate, organic calcium source, sodium chloride, magnesium oxide, yeast, methionine, lysine;

[0019] Vitamin and trace element complex, organic chromium, yeast selenium, organic zinc, rumen bypass glucose, protease.

[0020] This embodiment is further configured such that the organic calcium source is natural calcium carbonate or calcium citrate, and the addition amount thereof is 8-12% of the total weight of the premix.

[0021] This embodiment is further configured such that the soybean meal is processed through a heat treatment process, and the rumen bypass protein ratio is ≥60%.

[0022] This embodiment is further configured such that the amount of protease added is 3-5 g per ton of diet to reduce rumen methane emissions.

[0023] This embodiment is further configured such that the organic chromium is chromium picolinate, and the addition amount is 0.02-0.05% of the total weight of the premix.

[0024] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0025] Example: High-stubble organic silage is used as the primary roughage to provide physically effective fiber; heat-treated soybean meal increases rumen-pass protein to over 35% of total protein; and corn DDGS and organic corn flakes are combined to provide slow-release energy. Per ton of ration: 320 kg of organic whole-plant corn silage; 32 kg of heat-treated soybean meal; 18 kg of corn DDGS; 20 kg of organic corn flakes; and 6.25 kg of premix. Preparation process: Silage is cut to 2-3 cm lengths, soybean meal is steamed at 120°C for 20 minutes, and the premix is ​​mixed in stages to ensure uniformity. The premix features the following: an organic trace element system: yeast selenium boosts immunity, and organic zinc protects hoof health; a metabolic regulation system: rumen-pass glucose stabilizes blood sugar, and methionine protects liver metabolism; and an environmental improvement system: protease reduces methane emissions, and sodium bicarbonate buffers rumen pH.
