A cow weighing 55 kilograms.
You can feed up to 5.59 kilograms of concentrate every day.
Two weeks * * * Feed 6O70Kg.
In order to get more nutrition for dairy cows after calving, the feeding amount of concentrate should be increased to O 45 kg per day until it reaches the peak of milk production or free feeding.
And give plenty of drinking water to reduce digestive system diseases of dairy cows.
This method is limited to high-yield cows, and it will lead to obesity for low-yield cows.
Second, the challenge feeding method cows must maintain a good nutritional state before entering the dry milk period. After entering the dry milk stage, on the basis of feeding only high-quality roughage, O 45 kg concentrate is fed every day.
After l weeks, let them eat all the concentrate, but the maximum intake per day should not exceed l5 kg.
Moreover, it is only limited to the high-energy feed of about l2 weeks, and the feed should be prepared according to the maintenance needs and normal production requirements in the future.
Thirdly, the replacement feeding method changes the diet composition every 7lO days, mainly by adjusting the ratio of concentrate to roughage, but the total nutrition of the diet remains unchanged.
For example, from 20 days after delivery, cows are fed 8 kg hay, 10 kg silage and 7 kg concentrate every day.
After feeding for 1 week, concentrate decreased to 3kg, hay increased to 1kg, silage increased to 30kg, and milk yield did not decrease.
After three consecutive weeks, the concentrate feed will be reduced to 45 kg, the hay will be increased to 14 kg, and the succulent plants will be increased to 40 kg. When the milk yield did not decrease, the concentrate gradually increased to 1 13kg in the next week, and the milk yield continued to increase.
