30 days before cows dry milk
It is a time when the cows are fully rested, promote fetal growth and development, repair body tissue, accumulate nutrients, and renew breast tissue. Cows are affected by endocrine and dry matter intake is significantly reduced. It can be seen that dry milking is necessary to increase milk yield and maintain cow health. 13 70 days after childbirth is the initial stage of lactation. During this period, the dry matter intake of dairy cows has not completely recovered, about 15% lower than the late lactation period. A few days after delivery, the appetite is the worst and food intake is low, while the amount of lactation is increased every day (4 to 8 weeks post-partum, lactation peaks occur), resulting in nutrient deficits. In order to supply the energy needed to produce milk, cows consume fat while suppressing body fat synthesis.
