1. Before breast-milking, wash the breast water temperature at 45°C-50°C, scrub the breast with a warm towel first, then dry the breast with a wrung towel.
2, breast milk massage before full massage method is usually there are three kinds of ways: 1 with both hands supporting the breast gently, rub around, from top to bottom in turn, each rubbing 3-4 times, about half a minute. 2 Use your fingers to excite the nipple. Do not exceed 1 minute for more than 2 minutes. This will cause the nipple to become traumatic and cause mastitis. Do not over stimulate, so as not to cause pain. 3 top collision massage method, imitating the action of the lamb eating milk against the top of the breast, both hands loosely hold the base of the two nipples, knocked up 2-3 times, then milking, this massage method can be done in sequence. Scrub and massage time should not be too long, generally not more than 3 minutes.
3. Use a two-handed fist to squeeze the milk. First, close the base of the nipple with your thumb and forefinger, and block the hole between the nipple cavity and the milk pool to prevent backflow of milk. Then lightly and forcefully press the middle finger, ring finger, and small hand to pressurize and push the milk out. After each squeeze, the thumb and forefinger are immediately relaxed, and then they are clenched again. During operation, both hands should hold the two nipples respectively. The movement should be light and agile, the grip strength should be uniform, and the speed should be consistent. When the individual nipples are too short to be squeezed, the squeezing method can be used to hold the nipples with the thumb and forefinger, and slide the milk from the top down.
4, milking speed is generally 80-100 times per minute squeezed, squeezed a sheep takes 3-4 minutes. Every milking must squeeze milk to clean milk. The remaining milk can easily induce mastitis, and it can also reduce milk production and shorten the lactation period.
5, to properly increase the number of milking speed and how much milk secretion, and breast pressure is negatively correlated, that is, the smaller the pressure inside the breast, breast milk faster and more. Therefore, increasing the number of milking and reducing the internal pressure of the breast can increase the speed of lactation and increase milk production. It is estimated that high-yielding sheep can increase milk production by 20% to 30% after being squeezed twice a day, and in a good feeding management situation, milking twice a day can increase milk production by 12% to 15%. Normal sheep are squeezed twice a day, and high-yielding sheep are squeezed three times a day.
Milking should be done in such a way as to "set three times," that is, to schedule, set people, and set the venue every day. It should not be changed casually. In addition, the milking environment must be kept quiet.
6, each milking should carefully check the breast condition such as found nipple dry, broken or red breast swelling, heat pain, milk mixed with bloodshot or floc should be promptly treated. To prevent mastitis, 1% iodine solution or 0.5%-1% solution of chlorhexidine sodium hypochlorite can be used to soak the nipple after each squeeze.
7, dry milk should be timely in order to enable the ewes to timely replenish the body nutrition, to ensure the normal growth and development of the fetus, is conducive to the next lactation period to obtain high yield, according to the lyrics of ewe, different age, in the ewes pregnancy 2-3 months At that time, milking is stopped 2-3 months before delivery. In addition, 800,000 units of penicillin can be injected through the nipple, which can effectively prevent mastitis in dairy goats during the dry period.
