Ways to increase dairy milk production in winter
To optimize milk production in dairy cows, several key management practices should be implemented from the beginning of their lactation period. First, maintaining consistent lighting is crucial. For the first 60 days after calving, ensure that cows receive 16 hours of light daily. This helps regulate their biological rhythms and can lead to a milk yield increase of over 10% compared to natural light conditions.
Second, supplementing with carotene has proven effective. Providing 7 grams of carotene supplements 30 days before and after milking can result in an additional 200 kg of milk per cow during the lactation period. This supports better udder health and overall milk quality.
Third, feeding potassium-rich diets can significantly boost milk output. Potassium plays a vital role in milk synthesis, and by including such feeds, cows can produce 5–10% more milk daily. It’s essential to balance potassium intake for optimal results.
Fourth, adding baking soda to the diet can enhance milk yield and prolong peak production. Feeding 100 grams of baking soda per day during lactation helps maintain high milk output for up to seven months. When combined with a ration of 40% roughage, 60% concentrate feed, 1.5% baking soda, and 0.8% magnesium oxide, milk production can increase by 3.8 kg per cow per day.
Fifth, incorporating nitrogen and sulfur into the feed through urea and alkali-treated water improves silage quality. Mixing 5 kg of urea and 0.5 kg of alkali nitrate per ton of green corn stalks increases milk production by 7.3–10.3%. This enhances the nutritional value of the feed and supports better digestion.
Sixth, using phosphogypsum in the diet not only provides calcium sulfate but also adds trace minerals like potassium, sodium, and iron. Adding 71.5 grams of phosphogypsum per cow can increase milk production by 1.7%, while reducing feed costs per kilogram of milk produced by 11.4%.
Seventh, ensuring adequate salt intake and access to warm water is important. Adding 0.18–0.24% salt to dry feed and keeping drinking water above 17°C can improve hydration and milk output by up to 10%.
Finally, encouraging regular exercise can also contribute to higher milk yields. Allowing cows to move freely in the farm during sunny midday hours for about an hour each day helps stimulate circulation and overall well-being, which in turn supports increased milk production. These strategies, when combined, can significantly improve both the quantity and quality of milk produced by dairy cows.
