Seven strokes to send milk to winter cows prolific milk
Sun Dehua, a large dairy farmer at Jianguo Village, Zhangcao Village, Jiangcao District, Ganzhou City, has been engaged in dairy farming for more than 20 years. Many dairy cattle farmers have low temperatures in winter and spring (early spring) seasons, and the weather is cold. Dairy cows have large amounts of heat and are affected more or less by low temperatures, resulting in reduced milk production. Sun Deming's dairy cows still maintain high yields during the winter and spring (early spring) seasons. He said that there are seven major tricks that allow the winter cows to produce more milk.
Raise Sherwin
Grasp the insulation of cows. The optimum temperature for black-and-white cows is 8°C16°C. Closed thermal insulation barn can not reach the requirements at night, can increase the stocking density, cows can be closed when the cowshed idle part. Or use simple plastic shed culture, can increase the temperature of the cowhouse. As long as the feeding is good, the milk production will not drop.
Supplemental lighting
With a closed warm house to raise cattle, absorb less light, can increase artificial lighting, not only increase the temperature of the cowhouse, but also increase milk prolactin, increase milk production. The method is to take less than 16 hours of light during the day and supplement it with artificial light for 16 hours. For 26 weeks, daily milk production per cow can be increased by 10%.
Drinking warm water
In winter, cows eat hay, which requires large amounts of water. If drinking water is insufficient, cattle do not love to eat grass and even get sick. It was determined that cows need 5 kg of water for every 1 kg of dry feed eaten. Cows that drink enough water in winter have better appetite than those who do not drink enough water. Better use of a large amount of pastures can help the wintering of cattle. Therefore, the number of drinking cows should be no less than 3 times a day. And be sure to drink close to body temperature (38 °C 40 °C) of warm water. Avoid drinking cold water and ice slag water, because cattle drink cold water, ice water will take away a lot of body heat, reduce cattle body temperature, cattle susceptible to diseases, will also seriously affect milk production, therefore, must use warm water to drink cattle, continuous water.
Feed high heat feed
In winter and spring, the weather is cold, and the body of the cow radiates large heat. To keep warm, the required amount of heat should be increased. Every day, the amount of mixed concentrate should be increased by 5% to maintain a good sensation, so as to ensure the normal milk production and increase the milk yield of dairy cows. At the same time, feeding silage, hay, etc., can increase milk production by about 10%. Young vegetables, potatoes, beets and other young, juicy, nutritious, dairy cows love to eat, can quickly increase milk production. In particular, sugar beet contains oxidizing enzymes, which can effectively increase the milk production of dairy cows and is a good feed for milking cows.
Brush the body
In cold winter days, the bovine vascular contraction of the body and persistence of brushing the body of the bovine body with a brush can promote blood circulation of the bovine and have a significant effect on increasing the milk production of dairy cows. Milk production can be increased by 8%10%.
Hot compress and massage breast
Adhering to the use of 53°C 56°C hot water to wash the breasts and hot breasts can rapidly expand the breast blood vessels, increase the amount of blood flowing to the breasts, strengthen the synthesis of milk fat, and stimulate the breasts to discharge more milk. Breast massage during pregnancy can promote breast development, increase milk production, the effect of the initial distribution of cows is more obvious. Massage breasts before milking can stimulate rapid expansion, easy milking, and more milking. After breast milking, the remaining milk can be squeezed out, which can increase milk production and milk fat percentage. At the same time increasing the number of milking cows, 23 times a day to squeeze, both to speed up blood circulation, metabolism, but also increased milk production.
Feeding congee
In winter, cows are fed hot porridge at a temperature of about 38°C. Not only does the cow love to eat, it is easy to digest and absorb, but it also enhances the cow's ability to resist cold and increase milk production.
