In order to increase the milk production of dairy goats, scientific feeding and management methods should be adopted to select the appropriate age of the ewes for timely breeding, the rational breeding of pregnant ewes, the careful feeding of the ewes during lactation, and proper milking techniques. Avoid damage and harm to dairy goats during production and raising, and artificially reduce milk production. Specifically, the following measures should be taken:
1. Reasonably raise pregnant ewes. During pregnancy, ewes should be fed daily feeds such as bean cakes that are rich in protein. For pregnant ewes, prevent violent eviction from fright, and do not allow pregnant ewes to drink too cold water and eat spoiled feed, otherwise, it can easily lead to miscarriage of ewes. Ewes who are still milking during pregnancy are generally required to reduce the amount of condiment feeding and the number of milking during the two months before delivery. Gradually stop the milking. The last milking must be completely squeezed to prevent it. Causes mastitis.
2. Carefully raise the lactating goats. In the 15 to 20 days after the delivery of milk, the concentrate and succulent feed should be gradually increased to increase milk production. About 1 month after the delivery of milk, the amount of lactation reached a peak. At this stage, high-quality green and hay-based or silage materials should be used, and compound feed should be added. About 2 kilograms of sheep with a daily milk output were fed with 0.4 kg of cornmeal and 0.1 kg of soybean cake. The sheep with a daily milk output of about 3 kg had a daily feed of 0.5 kg of cornmeal and 0.2 kg of soybean cake. In addition, add 3 kg of salt and 2 kg of bone meal for every 100 kg of material. And to provide adequate drinking water, otherwise affecting feed intake, affecting lactation.
3. Take the right milking technique. Milking should be done in a regular, fixed, and fixed position, and the milking environment should be kept quiet. Before milking, first clean and disinfect dairy goats' breasts, nipples, and milking staff's hands. Use a warm towel around 45°C to scrub the breasts and nipples. Massage your breasts thoroughly before milking. Do not exceed 1 minute. The milking posture must be correct. The milkmaid should sit on the stool and stick his shoulders close to the shoulders of the goats. Hold the two nipples of the goats in the right and left hands. Do not go too loose or too tight. Feel comfortable. The milking staff must be able to move at one go. Speed ​​control is 80 to 100 times per minute. It takes 3 to 4 minutes to squeeze a sheep. Do not yell at the sheep so as not to affect the milk production. Each milking must squeeze the milk clean, avoiding mastitis, and also reduce milk production and shorten the lactation period. General sheep milking 2 times/day, high-yielding sheep milking 3 times/day.
4. Maintain reasonable exercise. Pregnant ewes stick to proper exercise to prevent compulsive labor; milk goats with high milk production adhere to proper exercise can enhance physical fitness, promote digestion and improve production performance. If the house is kept in captivity, the sheep should be driven to exercise for only 1 to 2 hours every day. Grazing is the ideal sport. It should be about 4 hours per day. Do not grazing on rainy days and avoid parasitic diseases.
5. Do a good job of pest control and epidemic prevention. Each year should be carried out once in spring and autumn. Medicinal baths are generally available for ectoparasites and are performed in sunny and windless weather. 0.5% trichlorfon is used. Pregnant ewes do not have a medicinal bath. For internal parasites, choose the appropriate drugs.
