In summer and autumn, the temperature changes greatly during the replacement period, and various pathogens are prone to breeding and breeding, which may cause disease, resulting in the death of cattle due to mass and epidemic diseases, resulting in large loss of farms. Therefore, Huinongwang Xiaobian suggested strengthening farm management and disease prevention. In the summer and autumn, we should pay special attention to the prevention and treatment of the following two kinds of cattle diseases.
First, attention should be paid to the prevention and control of cattle epidemic fever during the summer and autumn alternation
Cattle fever is an acute, highly contagious disease that is easily caused by high temperature in cattle. It mainly occurs in dairy cows and yellow cattle. The symptoms of lactating cows are the most serious, and the incidence of calves is low. The disease has a very obvious seasonality, which occurs mostly in the summer and autumn when the climate is hot and the rainfall is high.
The main manifestations of sick cows are anorexia, sudden drooling, runny nose, and high fever (above 41.6 °C). If the treatment is not timely, the joints will be stiff, lying, and unable to stand. Cattle fever has developed rapidly. Generally, cows have symptoms such as anorexia, salivation, and salivation in the morning. In the afternoon, the sick cows have high fever. After the timely infusion, the fever can be significantly improved on the second day, but the flow of a few sick cows Symptoms such as convulsions and salivation will continue for a long time. Although the fatality rate of cattle is not high, it can cause milk production in dairy cows to drop, miscarriage, stillbirth and lying down.
The treatment principle of the disease is early detection, early isolation, rational use of drugs and proper care. In order to prevent the sick cow from suffocating due to difficulty in breathing, oxygen can be given to the cow or bloodletting therapy can be taken; in the high temperature period, it is recommended to feed the cow with compound antipyretic such as Anjibi Lin and An Nai. According to the symptoms of sick cows, drugs such as cardiotonic, diuretic, stomachic and sedatives should be used for remission.
For areas where cattle fever is not affected and threatened by the disease, it is necessary to strengthen the management of dairy farms, strictly prevent, quarantine and isolate measures, pay close attention to the epidemic situation in various regions, and do not transfer cattle from diseased cattle farms and areas. Vaccination is given to cattle before the onset of the hot season from April to May each year.
Second, the summer and autumn alternation should pay attention to the prevention and treatment of beef belly disease
The disease of the cow's belly is also called "rumen suffocation". The disease occurs mostly in summer and autumn. The main reason is that the cow eats a lot of young and juicy grass, especially legumes such as cockroaches. These grasses, which cannot be moved down due to excessive consumption, generate a large amount of gas in the rumen for a short time, causing the rumen to rapidly expand. As a result, the abdomen of the diseased cow is enlarged, especially the left ankle is more prominent. In severe cases, it can even be higher than the back. At this time, the compression is elastic and beaten with drum sound. The sick cows showed mental distress, the rumors stopped, the heart sounds obviously increased, the breathing performance was difficult, and they often looked back and looked at the abdomen. Finally, they died due to rupture of the rumen.
In the summer and autumn, when you feed the cows with young grass, you should add some high quality hay. For sick cattle, apply a trocar to puncture the rumen to release gas, and inject 50ml kerosene or 20ml into the rumen to the rumen, and use about 100g of cumin, about 100g of garlic, about 250g of vinegar, mix and mashed with vinegar. 1 time of filling.
The above content is the two kinds of cattle diseases that need to be guarded against in the summer and autumn cattle breeding organized by Huinong. I ask the farmers to pay attention and do early prevention and early treatment.
Handrails play a very important role in the aging of the family. Through a small handrail, create a safe and secure living environment for the elderly at home. When installing the handrail, pay attention to determine the installation height of the handrail according to the height of the elderly at home. The armrest is located at the crotch of the elderly. Generally speaking, it is about 80 to 85 cm from the ground. In order to provide safe and effective support for the elderly, different products need to be selected according to different installation conditions. Some families want to install handrails on non-load-bearing walls. We suggest that they install lining plates first, and then install handrails on the lining plates.
When selecting the material of the handrail, pay attention to the coordination with the furniture environment, create a warm atmosphere, avoid making it cold and hard, and do not give the elderly the illusion of "being a patient". For example, the wooden handrail in the video looks very warm and feels good. It is suitable for the elderly.
