Ten ways to increase milk production in dairy cows
In recent years, phosphogypsum has been explored as a feed additive in some foreign countries. When added to the base diet of dairy cows at a rate of 71.5 grams per cow, it can boost milk production by 1.7%, increase milk fat percentage by 10.5%, and reduce feed consumption per kilogram of milk by 11.4%. This shows the potential of using phosphogypsum as a cost-effective supplement.
Another method involves feeding porridge to cows. Compared to dry or wet feed, porridge-based diets have been shown to increase milk production by up to 31%. The preparation process includes adding a small amount of salt to the powdered concentrate, mixing it with a little water, and then cooking it until the water boils, stirring for 5 to 10 minutes.
Carotene supplementation has also shown promising results. Russian cattle breeders added 7 grams of carotene to the diet of cows 30 days before calving and 92 days postpartum. This led to a shortened lactation period by about one week and an increase in milk yield by 200.8 kilograms per lactation cycle.
Oyster shell sunflower seeds are another effective feed option. Rich in protein and fat, they can be added at a rate of 10–20% in the feed, which has been found to increase milk production by approximately 15%.
Feeding fish and shrimp is another strategy. Adding 0.3 kg of cooked fish and shrimp to each cow's daily diet can increase milk output by 2 kg. In the early stages of lactation, adding 0.75 kg of fishmeal daily can raise fresh milk production by about 1.5 kg per day.
Sodium bicarbonate has also been studied in the U.S. for its effects on dairy cows. Feeding 150 grams per cow daily, which makes up 0.8% of the dry matter in their diet, significantly boosts milk production during peak periods and maintains high yields for 32 weeks. This leads to an average of 176 kg of milk per cow and a 3.1% increase in milk fat content.
Light exposure plays a crucial role in milk production. Research from the University of Michigan showed that allowing cows to receive 16 hours of light per day during the first 60 days of lactation can increase milk production by 10%. In winter, increasing light exposure to 16 hours can lead to a 10% higher milk yield compared to natural lighting.
Postpartum management is equally important. The 3rd to 8th weeks after calving are critical for milk production. Cows that give birth in summer tend to produce 10 kg less milk than those calving in other seasons. Therefore, careful planning of breeding cycles to avoid summer calving can help maximize milk output.
Hoofing, or trimming hooves, has proven beneficial. A German study found that cows with trimmed hooves before grazing produced 200 kg more milk annually. At China Agricultural University, an experiment showed that 30 cows in the experimental group had a net milk increase of 436.5 kg over 15 days after hoof trimming, resulting in a 4.43% increase in production.
Parasite control through deworming has also been shown to improve milk yield. Using thiabendazole to remove nematodes from the digestive tract of dairy cows increased milk production. In 21 pastures in Hokkaido, Japan, dewormed cows produced an average of 409.3 kg of milk per lactation, with an additional 12.6 kg of milk fat.
These techniques highlight various ways farmers can enhance milk production through improved nutrition, environmental management, and health care. Linyi County Government Office
The main effects and production process of Amino Acid chelate: improve bioavailability: after the metal ions in amino acid chelate are combined with amino acid, its absorption and utilization in human body or plants and animals are greatly improved, improve stability: amino acid chelate is more stable in and out of the body and does not easily react with other components, thus maintaining the activity of minerals.
Promote plant growth: In agriculture, amino acid chelate can be used as trace element fertilizer to improve the absorption of trace elements by plants and enhance their disease resistance and growth rate.
High purity amino acids and metal salts are selected as raw materials. Common amino acids include glycine, lysine, etc. Metal salts include zinc sulfate, magnesium sulfate, etc. The amino acid solution is mixed with the metal salt solution in a certain proportion and the reaction is carried out under suitable pH and temperature conditions. This process is usually carried out in a stirred reactor to ensure a homogeneous reaction.
The quality of the produced amino acid chelate is tested to ensure that its purity and stability meet the requirements. Finally, the product is packaged to prevent moisture and contamination.
Amino acid chelates are widely used in human and animal nutritional supplements and plant fertilizers because of their high efficiency and safety.
