The amount of brewers' grains fed to cows should be moderate. Based on local experience, feeding each cow 7–8 kilograms per day has been shown to significantly improve production performance without causing any adverse effects. For lactating cows, the daily intake should not exceed 10 kilograms, especially during summer when spoilage is more common.
Fresh brewers’ grains contain a high water content and can spoil quickly, so it's essential to ensure they are fresh before feeding. If they cannot be used immediately, they should be stored properly to maintain quality. In hot weather, it’s best to feed them daily. Additionally, adding 150–200 grams of baking soda per cow per day can help balance the diet and support digestion.
It's important to consider the nutritional balance when feeding brewers’ grains. While they are rich in crude protein, they tend to be low in calcium and phosphorus, and the mineral proportions may not be ideal. Therefore, it's recommended to increase the concentration of dietary concentrates and pay close attention to calcium levels. Adding 2% bone meal to the concentrate mix can help improve milk production and overall health in dairy cows.
Lactating cows that have given birth within the past one month should avoid excessive feeding of brewers’ grains, as this could worsen negative energy balance and delay the recovery of their reproductive systems.
In cases of chronic poisoning due to improper use of brewers’ grains, it’s crucial to reduce the feeding amount immediately and provide appropriate symptomatic treatment to minimize harm. Always monitor the animals closely and adjust feeding practices based on their condition and environmental factors.
