Dry dairy cows (or dry dairy cows) refer to cows that have passed from the stop of milking to the first 15 days of calving. The goal of this phase of the campaign is to ensure the development of the fetus, recovery of the sensation, and nutrient reserve.
The body condition of dry cows should be maintained at a moderate level. Cows are over-fertilized and are prone to dystocia. Most of the post-partum appetite suffers from ketosis. Therefore, you should feed more hay within 10 days after stopping your milk, and then adjust the diet according to your body condition, breast expansion, and appetite. If the body condition of the cow is poor and the breasts are not inflated, the concentrate may be fed in an appropriate amount. If, on the other hand, the breasts are inflated, the concentrate may not be fed. The general dietary dry matter intake should be controlled at 2% of the cow's body weight, and the concentrate feed amount is 0.6-0.8% of body weight. The crude-to-coarse ratio is 35:65, and the general weight is 600 kg. The output of lactating cow dry milk is: 4 kg of concentrate, 20 kg of silage corn, and 5 kg of hay. In order to improve the health of dairy cows, diets should also be supplemented with minerals, vitamins and salt.
Conditional dairy farms, dry dairy cows can exercise for 2-3 hours a day, which is conducive to childbirth, but also can prevent postpartum placental clothing, sputum and limbs disease.
