1. Adhere to self-support
In order to ensure the safe production of beef cattle, the most effective measure is to choose healthy, good-quality breed bulls and cows, and breed yaks, which are both cheaper and healthier than the market to buy cows. If you can use the heterosis of the hybrid generation better, you can improve the quality of cattle and reduce the cost of cattle. The purpose of self-cultivation and self-cultivation is to prevent the introduction of cattle into the disease and cause the spread of the disease. Even when it is necessary to introduce improved varieties, it is necessary to do a good job of quarantine and isolation observation at the time of introduction. After 30 to 45 days, the quarantine department decides whether or not there is an epidemic disease and then does it. However, it is necessary to prohibit the introduction of cattle from affected areas to control the occurrence of infectious diseases.
2. Strict health and epidemic prevention
To run a cattle farm, only cattle can be raised, other livestock and poultry can't be kept, and even surrounding animals can't be allowed to enter the farm to facilitate the health of cattle. The cattle farm should improve the regular and emergency disinfection system. There should be disinfection rooms and disinfection pools at the entrances and exits of the farms. The cattle farm is to be sterilized at least once a quarter, the cowshed is to be sterilized once a month, the cow bed is to be sterilized once a week, and the feeding troughs and utensils are to be regularly sterilized. The sterilization of the cattle environment can be disinfected once a month with 0.1% benzalkonium chloride or 0.3% peracetic acid to facilitate the reduction of bacteria and other microorganisms in the environment. During the midwifery, breeding and treatment of cattle, the body must be disinfected in the hindquarters, genitals and treatment sites to reduce the chance of pathogen infection of cattle. The cattle farm refused to enter the country. When they needed to visit, they should be thoroughly disinfected and change their shoes. Keep the barn clean and hygienic. When excrement and its pollutants are removed, it must be promptly pushed to the off-site fecal field for compost fermentation. The diseased cattle should be isolated in time, and the dead cattle and their products should be treated as harmless according to relevant regulations. Use 10 to 20% quicklime or 1% to 2% fire alkali water to completely disinfect and eliminate the source of infection so as not to spread the disease. The staff of the cattle farms are required to have regular medical examinations. If infectious diseases such as tuberculosis are detected, they should be promptly recalled. Personnel and vehicles must enter the site to change their clothes and disinfect, and uniforms cannot be worn out of the court.
3. Pay attention to plan immunity
According to the regulations and requirements of the epidemic prevention department, the cattle farms are regularly vaccinated against the relevant infectious diseases. Healthy cows will undergo a quarantine of tuberculosis and brucellosis every spring and autumn. Detection of positive cattle should be promptly culled. For suspected cows, segregation and re-examination, such as the emergence of suspected cows 2 times in succession, should be treated as positive cattle culling. Every year in the autumn, cows of more than one week old need to be immunized with spores of anthrax, followed by a refill of the spring of the year to strengthen immunity.
4. Regular deworming care
Beef cattle are susceptible to parasitic diseases in both feeding and grazing. They not only seize the nutrients of cattle, but also cause cattle to lose weight and become ill. They also reduce the economic benefits of beef cattle. Therefore, beef cattle with parasites are not harmful. Deworming should be selected for high-efficiency, low-toxicity, broad-spectrum, easy-to-use thiabendazole and ivermectin, etc. to feed cattle fasting seasoning. If pests are to be driven on a large scale, they should first be tested in a small area and be fully developed after gaining experience. It is best to repel insects in specialized places with isolation conditions. After deworming cattle, they should be isolated for a certain period of time until the parasites and eggs are discharged. Insects and eggs and contaminated excreta are collected at any time after insect repelling. Composting and fermentation can prevent the eggs and larvae from contaminating the external environment, prevent the spread of pathogens, and help protect the health of beef cattle, thereby reducing the worms of beef cattle. Quantity, this can significantly improve the deworming effect of beef cattle. The nutrients digested by beef cattle can be effectively utilized, with fast fattening, early slaughter, and high profitability.
5. Grasp environmental health
Maintaining the environmental hygiene of cattle farms and cattle houses can effectively reduce and prevent the infection of pathogenic bacteria, cut off the transmission of diseases, and control the contact between pathogenic microorganisms and susceptible herds. To strengthen the environmental hygiene management, the key is to do a good job of beef cattle breeding and management to improve the disease resistance of cattle. Keep the cowshed dry, ventilated, cool, disinfect, control and eliminate the source of infection. Early detection and treatment of diseased cows, isolation of pathogenic cattle, to prevent the spread of pathogens. To achieve early disease, no disease early prevention. Timely implementation of drug prevention and immune prevention for cattle disease enhances the ability of cattle to resist disease infestations. The excrement of diseased cattle must be cleaned at any time and strictly fermented.
6. Effective prevention of poisoning
To prevent pesticide poisoning, to prevent feed and drinking water from being contaminated by pesticides, and to control the source of green feed in particular, feed crops and green grass that have been sprayed with pesticides cannot be grazing and mowing. Water from the farmland is polluted by chemical fertilizers and pesticides and cannot be used to drink cows. Store the feed storehouse to be dry and ventilated. The temperature should not be too high and prevent mildew in feed. It is forbidden to feed cows with raw cakes such as mouldy feeds and non-toxic cottonseed cakes. When cattle are fed with potatoes, they must be rotted, germinated, and green. Regardless of feeding or grazing should pay attention to prevent toxic grass, wood food poisoning. To prevent the poisoning of rodenticides, the toxicity of rodenticides is large, and cows can eat it and cause hemorrhagic gastroenteritis or acute poisoning and can not be ignored.
Welding mask is a type of headgear used when performing certain types of welding to protect the eyes, faceandneck from flash burn, ultraviolet light, sparks, infrared light, and heat.
welding
masks are most commonly used with arc welding processes such as
shielded metal arc welding, gas tungsten arc welding, and gas metal arc
welding. They are necessary to prevent arc eye, a painful condition
where the cornea is inflamed. welding masks can also prevent retina
burns, which can lead to a loss of vision. Both conditions are caused by
unprotected exposure to the highly concentrated ultraviolet and
infrared rays emitted by the welding arc. Ultraviolet emissions from the
welding arc can also damage uncovered skin, causing a sunburn-like
condition in a relatively short period of welding.
