Feeding and Feeding Methods From the 15 days before the cow's delivery to the peak of milk production (30 to 45 days after childbirth), it is necessary to feed more concentrate and less feed. Feeding 1.5 to 1.8 kg per day per cow from day 15 onwards of the cow, and then increasing it by 0.3 to 0.5 kg per day until feeding 1 to 1.5 kg of concentrate per 100 kg of body weight. Dairy cows can produce early milk, lactation peak, mid lactation and end of lactation during lactation. Dairy cows have peak milk production from January to March in the post-natal period, and milk production per month gradually decreases by 5% to 10%. According to this feature, dairy cows should continue to feed 0.3 to 0.5 kilograms of concentrate each day after delivery until the peak of milk production occurs, but the maximum daily feed of concentrates should not exceed 17 kilograms. After the peak period, the cows are raised according to normal standards.
The limited-feeding method provides pre-feeding restrictions for healthy and well-fed dairy cows. During the dry period, feed more quality succulent feed or hay and feed less concentrate (less than 4 kg per day). From the 1st week after delivery, feed 0.3 to 0.5 kg per head per day until each day. The material does not exceed 17 kilograms. The concentrate should be mixed and mixed so that the cow can eat freely and maintain it for 2 to 3 months.
Alternating feeding method To stimulate the appetite of dairy cows in order to achieve high and stable yield, high- and low-period alternating feeding of concentrates should be performed. From the 10th day after the delivery of the cow, 8 kg of green hay, 10 kg of silage (12 kg of green grass or vegetable leaves) and 7 kg of concentrate are fed every day for 1 week. Then, the concentrate was gradually reduced to 3 kg, the amount of hay on the day was increased to 11 kg, and 30 kg of succulent feed (grass, vegetable leaves, root tubers, etc.) were fed. The others were unchanged, and they were fed for 1 week. The concentrate was gradually increased to 13 kg until the end of the milk production peak period.
