How to raise cows in high temperature season

During the hot season, cows are prone to heat stress, which not only affects the normal milk production and breeding rate, but also reduces the cow's resistance and raises the incidence. In order to minimize the effects of high temperatures, the following points should be noted. 1, to improve the barn microclimate when the cowhouse temperature exceeds 30 °C, it will affect the body surface heat of dairy cows, resulting in metabolic disorders. Therefore, in the high temperature season, all the vents of the cowshed should be opened and the air circulation should be strengthened to reduce the temperature of the cowhouse and eliminate the foul gas in the house. Conditional fans or curtains can be installed. After milking in the afternoon, it is also possible to cool the bovine body surface spray directly. 2. Adjusting the structure of the diet Due to the cold and heat-prone cows, the intake of dairy cows will decline during the high temperature season. In order to keep the cows' milk yield higher, the diet structure should be properly adjusted to reduce the proportion of crude fiber. In addition to the diversification of the types of concentrate, we must also increase the level of protein and feed more green grass such as high-quality green grass and vegetables. In addition, the feeding time can be adjusted by adopting the method of early morning feeding and late evening feeding, which can also increase the feed intake of the cow. 3, provide adequate drinking water General lactation of dairy cows daily water intake of not less than 100 kg. Water should be added to the sink, and enough sinks should be installed on the sports ground to ensure that the cows have sufficient drinking water and increase the amount of urine excretion to bring about excess body heat and reduce the increase in body temperature and sweat. Loss of body fluids. In order to promote the digestion of dairy cows and ensure the balance of water and salt metabolism, cows can drink 0.5% saline. 4, do a good job of cleaning the barn to clean up, remove the manure in a timely manner, and wash the ground with water, can not let the feces in the cowhouse fermentation pollution of the environment. To enhance ventilation and ventilation, to ensure that there is no odor, dry, cool, ammonia, carbon dioxide and other harmful gases do not exceed standards, and regular environmental disinfection. 5. Killing mosquitoes, flies, and flies not only bite the body of the cow, affecting its rest, resulting in a decrease in the amount of milk produced, and it can also spread diseases. Therefore, the screen door can be installed in the cowshed, and the bovine body can be sprayed with a dilution of 600-800 times of 90% trichlorfon to disperse mosquitoes and flies. However, it should be noted that the drug concentration should not be too high, there can be no odor, can not penetrate into the milk.

Rheumatoid arthritis (RA) is a chronic, etiology of inflammatory synovitis-based systemic disease. It is characterized by hand, small joints of the joints, symmetry, invasive joint inflammation, often associated with external organ involvement and serum rheumatoid factor positive, can lead to joint deformity and loss of function. According to statistics, the incidence of rheumatoid arthritis in women is 2 to 3 times that of men.It can occur at any age, high incidence of age 40 to 60 years old. People who has rheumatoid arthritis in the late, severe or long-term bedridden patients, due to combined infection, gastrointestinal bleeding, heart, lung or kidney disease can be crisis to life. The main purpose of treatment for Rheumatoid arthritis is to reduce the inflammation of the joints, inhibit the development of lesions and irreversible bone destruction, as far as possible to protect the function of joints and muscles, and ultimately achieve complete disease remission or low disease activity target. Treatment principles include 1. Patient education, 2. General treatment 3. Drug treatment 4. Immune purification 5. Functional exercise 6. Surgical treatment. Anti-Rheumatoid Arthritis drug treatment mainly includes non-steroidal anti-inflammatory drugs, slow-acting anti-rheumatic drugs, immunosuppressive agents, immune and biological agents and botanicals. Over the past decade, the treatment of extra-articular lesions and the emergence of new therapies, so that the efficacy of rheumatoid arthritis has been significantly improved. Most patients with rheumatoid arthritis can get a good control or even complete remission.
