Prevention and treatment of common diseases in spring sheep
Acute flatulence is due to long-term feeding of hay in winter, and sheep tend to overfeed when they occasionally eat grass in spring. Grass in the stomach acute fermentation, produce a large amount of gas, so that the rumen expansion, if the rescue is not timely or improper rescue methods will lead to sheep death. Rescue method: put a willow stick into the sheep's mouth, tie the two ends to the sheep's head, let the sheep chew, and massage the left side of the sheep with your hand to help exhaust. You can also peel off 5-10 cigarettes and shove the cut tobacco into the sheep's mouth twice. If you are mildly ill, you will be cured 1 hour later. Also available

It's good to feed the chickens with manganese sulfate.
Winter and spring is the peak incubation season for chickens. During this period, we should pay attention to adding an appropriate amount of manganese sulfate to the chicken feed. Because manganese is the activator of many enzymes, it plays an important role in the growth, development and reproduction of chickens. Lack of green feed in winter and spring, chickens often give priority to seed feed, but seed feed contains very little manganese, so chickens are easy to suffer from manganese deficiency in winter and spring. When the chicken is deficient in manganese, one is abnormal bone development, the leg bone is thick and short, bent, and the diseased chicken limps, which mostly occurs in 3-6-week-old chicks; second, it is in eggs.

Selection of drugs for Porcine parasites
There are many kinds of deworming drugs for pigs, but we should choose drugs with fast effect, easy to use, cheap, low toxicity and no drug resistance, as long as we choose them properly, we will get the effect of deworming. Anthelmintic drugs are divided into anti-nematode drugs, anti-trematode drugs, anti-tapeworm drugs and antiprotozoal drugs. Due to the different properties of the agents, even the anti-nematode drugs are not effective against all nematodes. For example, levamisole and albendazole are ideal nematode repellents at present, which are cheap, safe and reliable with low toxicity. And

How to do well the immunity of reserve pigs
1. The production and importance of good immunity of reserve pigs after the first injection of vaccine to pigs, the corresponding antibodies will be produced after a certain period of time, at this time, the antibody titer is low, the maintenance time is short, and they do not have the ability to resist pathogen invasion. but it laid the foundation for the establishment of effective immunity in the future, so it is called basic immunity. Re-inoculation of the same vaccine in a certain period of time can induce the recall response of memory cells after the first vaccination, which can quickly produce high titer and maintenance time in a short period of time.

Pork Chop White Urine Prevention Method
Fattening pigs and post-breeding sows excrete white lime-like substances after urination, and this situation sometimes occurs in young piglets, but it does not affect the normal feeding and growth of pigs. This situation is mainly caused by inflammation of the pig's urinary system-kidney or bladder, causing some metabolites to accumulate in the renal pelvis, and when it reaches a certain amount, it is accompanied by urine discharged to the body. Prevention and treatment methods: ① use antibiotic treatment, there are many antibiotics available, such as amoxicillin, enrofloxacin, ofloxacin, urofloxacin

Effects of different temperatures on Pigs and its Countermeasures
First, the effect of environmental temperature on pigs. 1. The effect on the health of pigs. In the environment of continuous high temperature, the resistance of pigs decreased significantly, the body heat balance was destroyed, the body temperature increased, coma, heat radiation disease occurred, and died in severe cases. In a low temperature environment, pigs contract peripheral blood vessels in order to keep warm, causing local frostbite. Low temperature can cause respiratory diseases, but also often cause rheumatism, arthritis and other diseases. Low temperature has a greater impact on piglets. According to statistics, half of the piglets who died were frozen to death or died of cold-related diseases.

Methods of preventing heat and cooling pigs in summer
Pigs are afraid of heat, in hot summer, if the method of preventing heat and cooling is not appropriate, pigs will get heatstroke and die in serious cases, causing unnecessary losses. The methods of preventing heat and cooling are as follows: 1. Suitable temperature: pigs have different requirements for growth and development because of their different body weight. For pigs weighing about 20 kg, the suitable temperature for the environment is 24 ℃, 23 ℃ for 50 kg, and 20 ℃ for 100kg. In general, the suitable temperature for pig growth is 15-28 ℃, and the best temperature is 22 ℃. If the temperature reaches 35 ℃, the cooling work can not keep up with the 45 kg body weight.

Effect of Light on Pigs
The light of piggery can be divided into natural light and artificial light according to different light sources. Natural illumination means that direct and scattered light from the sun enter the pig house through transparent structures such as doors and windows. Visible light accounts for 50% of the solar spectrum, and the remaining 50% is mostly infrared light and a small amount is ultraviolet light. The natural light of the pig house is generally expressed by the ratio of the total area of the pig house that can be transparent to the ground area of the house, which is called the lighting coefficient. Artificial lighting is illuminated by artificial light sources (incandescent or fluorescent lamps, etc.). Infrared light accounts for 60% of the spectrum of incandescent lamps.
