1. Scrubbing the breasts: Scrub the breasts before milking. Keep the water temperature at 45-50°C. Scrub with a wet towel, then wring out the towels and wipe them dry. This is not only clean, but also due to warm stimuli can make the blood vessels of the venous dilate, so that the blood flow to the breast increases, and promote lactation.
2. Massage the breasts: Massage the breasts before milking, give appropriate stimulation, and promote rapid breast discharge. There are three kinds of massage methods: First, support the breast with both hands, rubbing the left and right, from top to bottom in turn, each time rubbing 3-4 times, about 0.5 minutes; second is to use a finger to stimulate the nipple, about 0.5 minutes (More than 2 minutes, it will cause chronic papillary trauma, lead to mastitis), irritation should not be excessive, so as not to cause pain; 3 is to hit the massage method, which mimics the action of the lamb eating milk against the top of the breast, both hands loosely hold the base of the two nipples, up Colliding 2-3 times, and then milking, these 3 kinds of massage methods can be performed in succession, because the oxytocin in the blood is the highest concentration at 2 minutes after the start of stimulation, and then it drops sharply, ending about 0.5 minutes. For this reason, the time for scrubbing and massage should not be too long. Generally, it should not exceed 3 minutes. Otherwise, the most appropriate milking time will be missed, causing adverse consequences such as reduced milk production and increased breast morbidity.
3, boxing milking: the use of two-handed boxing method milking can cause strong milk reflection, crowded milk, the method is to use the thumb and index finger to close the nipple base, block the nipple cavity and the milk pool Hole to prevent milk flow four. Then lightly and forcefully press the middle finger, ring finger, and small hand to pressurize and push the milk out. After each squeeze squeezed milk, the thumb and index finger immediately relax, and then re-clenched, so rhythm a grip and loose repeatedly, operation hands to hold the two nipples, both hands should be light and agile, grip strength Uniform, uniform speed, alternating. For individual nipples that are too short to be squeezed, a squeezing method can be used. The nipple can be pinched with the thumb and forefinger and slid from top to bottom to extrude the milk.
4. Squeeze speed is faster: Because the reflection of milk ejection is dominated by nerves and there is a certain time limit, beyond a certain period of time, it will not squeeze out. Therefore, to quickly milk, the middle non-stop, usually 80-100 times per minute is appropriate, after squeezing a sheep takes 3-4 minutes. Avoid slow movement or slipping with one hand.
5, milk should be squeezed out: each milking must be squeezed, if the net is not squeezed, the remaining milk is easy to induce mastitis, but also reduce milk production, shorten the lactation period. Therefore, before the milking is over, a breast massage is performed to squeeze out the last drop of milk.
6, the appropriate increase in the number of times: the smaller the pressure inside the breast, the breast lactation faster and more. Therefore, appropriate increase in the number of milking, reducing the internal pressure of the breast can increase the rate of lactation and increase milk production. According to calculations, high-yielding dairy goats, under good feeding conditions, squeeze 2 times a day and squeeze 1 time to increase milk production by 20-30%, and squeeze 3 times a day and increase by 12-15% over 2 times. From a practical and convenient point of view, sheep should be squeezed twice a day, and high-yielding sheep should be squeezed three times.
7, to achieve three sets: that is, milking every day to be regular, fixed, set, do not arbitrarily change. In addition, the milking environment should be quiet.
8, check the breasts: milking should carefully check the situation of the breast, if found nipple chapped, broken or breast inflammation, redness, heat pain, milk mixed with bloodshot or floc, should be promptly treated.
9, bath nipples: In order to prevent mastitis, after each squeezed milk can choose 1% iodine, 0.5-1% chlorhexidine or 4% sodium hypochlorite soaked nipple solution.
10, timely dry milk: In order to enable the ewes to timely replenish the body's nutrition, to ensure the normal growth and development of the fetus, is conducive to the next lactation period to obtain high yield, should be based on eczema and age, the ewes pregnant for about 3 months, In other words, milking is stopped about two months before the birth, and it is gradually carried out. From the first day, it is squeezed 2-3 times. It is changed to 1 day and squeezed 1-2 times. It is changed to 1 day or every other day. Once a day, until completely stopped. After the last milking, 800-100,000 units of penicillin should be injected through the nipple, which can effectively prevent the occurrence of mastitis during dry period.
