Cow dry milk has "three strokes"

Dairy cow dry milk is generally performed at the end of 10 months of milk production or about 2 months before the expected date of production. Dry milk is suitable for 45 days to 60 days. Weak and older cows, first- and early-maturing cows, high-yielding cows, and poorly-conditioned cows may have a longer dry period of 60 days to 75 days. The dry period of cows with strong physique, low milk production, and good nutritional status can be as short as 30 days to 45 days.

Fast dry milk method

When dry milk is planned, it is necessary to stop the feeding of bad residue excipients, root tubers and juicy green feed to control drinking water and strengthen exercise. Appropriately reduce the amount of ingredients to be fed, gradually reduce the number of milking per day, disrupt the sequence of milking, and stop breast massage. So that the actual daily milk production has a significant decline every day, after 4 days to 7 days, when the daily milk production close to 8 kg to 10 kg milking, the last milking should be fully massaged, squeezed. Soak the nipples with 4% sodium chlorate or 3% chlorhexidine solution, then inject dry milk ointment and sterilize the nipple surface. After the milk is completely dry, smear the nipples with jelly rubber.

Sudden dry milk method

This method is simple and has no adverse effects on dairy cows. It is currently the simplest dry milk method. After the date of dry milk is determined according to the expected date of delivery, after normal milking, the breasts are fully massaged, the milk is squeezed cleanly, 5 grams of dry cream ointment is injected into each nipple, and milking is stopped. A small number of cows with high daily milk production still squeezed their milk after stopping for 2 days to 3 days. Nipples were injected with dry ointment. On the day of stopping the milk, the feeds for bad grains, roots and stems, and concentrates were started to be fed. The feed was reduced from 4 days to 5 days to the dry period. After 7 days to 10 days dry milk.

Gradually dry milk method

Change the feed from 10 days to 20 days before the planned dry milk, reduce grass, silage, juicy tuber feed, limit drinking water, stop exercise and grazing, stop breast massage, change the number of milking and milking time, 3 times milking Gradually changed to 2 times and 1 time, and then squeeze milk once every other day or every 2 days to 3 days. Each time the milk must be squeezed out, milking is stopped when the milk production drops to 4 kg to 5 kg.
