Comprehensive prevention and control measures of porcine pica
Pig pica is one of the problems often encountered in pig production, especially in the winter and spring when the light time is insufficient and the temperature is low. Improper feeding and management, environmental discomfort, imbalance of feed nutrition supply, disease and metabolic disorders are the causes of the disease. Due to long-term eclipse, pigs often cause growth retardation, weight loss and anorexia, causing unnecessary economic losses to pig farmers. 1. Clinical symptoms: pig pica is characterized by tail biting, ear biting, rib biting, navel sucking, especially eating chicken dung and urine.

Diagnosis and treatment of Bovine Taylor Disease
Bovine Taylor disease is a kind of bovine hematozoonosis caused mainly by the parasitism of Tyleria annulata in cattle. The disease is mainly transmitted by intermediate host ticks and occurs more frequently in spring. 1 the body temperature of cattle with clinical symptoms increased to 40 ℃ ~ 41.8 ℃, which was missed fever and maintained at about 41 ℃ in 4 to 10 days. A small number of diseased cattle showed relaxation fever or intermittent fever. with the increase of body temperature, diseased cattle showed depression, inability to walk and lagging behind, while some diseased cattle showed coma, lying on the ground, weak and fast pulse and increased respiration.

Nutritional exhaustion of cattle and its treatment
Bovine nutritional exhaustion generally occurs in winter and is dangerous in spring. Especially since last winter and this spring, it has been overcast and rainy for a long time in the south of the Yangtze River, the grazing time of cattle is less, and the time of house feeding is too long, which leads to more diseases and a wide range of diseases this spring, and the affected animals lose their economic value, seriously affecting farmers' spring ploughing and service. 1 the etiology of bovine nutritional failure is different from acute organ failure such as heart failure and renal failure. The fundamental reason is that there is a negative balance between nutrition supply and consumption, resulting in the storage of fat, protein and glycogen in the body.

Scientific preparation of feed for lactating sows
The task of sows is very heavy. In particular, lactating sows should not only provide their own nutrition, but also provide breast milk for the survival, growth and development of newborn piglets. However, the living and production environment of lactating sows in high temperature season is more disadvantageous, and high heat stress is a severe challenge for parturient sows. Therefore, how to scientifically allocate the summer diet of lactating sows and strengthen feeding management should be the problems that pig producers must actively consider and focus on solving. Optimize the configuration and improve the energy level

Different types of pigs have different immunity.
Immunity of backup pigs. The reserve pigs should be vaccinated with the following vaccine one month before breeding and after weaning sows: ⑴ classical swine fever vaccine, 4 doses each. ⑵ combined vaccine of porcine erysipelas and porcine pneumoconiosis, 1 copy per head. ⑶ porcine Japanese encephalitis vaccine, 1 dose per head. ⑷ porcine parvovirus vaccine, 1 dose each (inactivated vaccine can be vaccinated twice at an interval of 15 days). ⑸ porcine pseudorabies vaccine should be used according to the instructions. Immunity of parturient pigs. Parturient sows should be vaccinated with the following vaccines 15-40 days before delivery: ⑴ piglet Escherichia coli quadruple vaccine (K88, K99, 9)

Chicken stomach erosion
The disease is mostly caused by feeding inferior fish meal. [Main symptoms] Sick chickens are stunted, their combs are pale, their appetite is reduced, they are dehydrated, their feathers are unkempt, and they are lethargic. Sick chickens occasionally see dark black liquid flowing out of their mouths. Necropsy was characterized by erosion, ulceration and hemorrhage of the musculogastric mucosa. It mainly occurs in chicks of 3 to 6 weeks old and is sporadic, with mortality sometimes as high as 20%. The amount of fish meal should be controlled or not inferior fish meal. Drinking water with 0.1% potassium permanganate at the beginning after onset. Vitamin K(5) can be added to feed

Occurrence and control of epidemic diseases in different feeding stages of pigs
The incidence of swine fever, swine erysipelas and porcine lung disease are collectively referred to as the three major infectious diseases of pigs. In China, the total mortality rate of infected pigs accounts for about 8% of the total, and the mortality rate of pigs in areas with better prevention and control is also 5%. Therefore, the level of prevention and control of pig disease should be improved. If the total mortality rate of pigs can be reduced by one percentage point every year, which is equivalent to an increase of 5 million pigs, what a great wealth it is. According to the relevant statistics,

The champion of bouncing-- bouncing fish
In China's coastal high tide areas or brackish water estuarine shoals, there lives a small fish with a large and square head, a protruding eye and a rotational eye, and a muscle handle at the base of the pectoral fin, which can be used as an organ to support and crawl on land. the left and right ventral fins healed into a sucker. Catfish have the habit of foraging out of water, whenever the tide goes out. It often relies on the pectoral fin muscle handle to crawl on the mud to find food, or climb to the rocks and mangrove bushes to prey on insects, or climb to the stones to bask in the sun. When it comes out of the water, it's developed.

Autumn tube pond fish catch and fattening
The golden autumn season is the peak season for fattening and fattening of fish. to do a good job of feeding and management in this period is the key link to increase fish production and improve economic benefits. The main measures are as follows: first, improving water quality and maintaining good water quality is an important condition for fish to gain fat. It is necessary to inject new water frequently and increase the amount of dissolved oxygen in the water. Generally, about 5-6 days to add new water, each change of water to 15-25 centimeters for degrees. Sprinkle quicklime solution 2 or 3 times a month to eliminate bacteria and increase calcium. A pond with a general depth of 1.5 meters per mu

Summer Flower Fish: mainly raise one fish without putting carp feed combined with strong feeding
Summer flower fish species are small and delicate, and their ability to resist adverse environment is weak, coupled with the transformation of summer flower feeding at this stage, but the structure and function of their digestive system are not yet well developed, and their digestive ability is poor. If the feeding method is improper, there will be a large number of deaths. Through the experiment, the author found that the following culture methods can significantly improve the survival rate and culture benefit of summer flowers. Scientific stocking and reasonable matching of traditional breeding methods are mainly mixed culture of multiple varieties. However, from the perspective of production practice, due to the different eating habits of fish, this kind of culture

Several common green environmental protection fishery drugs
Although quicklime and salt are not special fishery drugs, they have good effect in preventing and controlling aquatic diseases, and do not pose a threat to the environment, and there is no drug residue problem. Sprinkling quicklime regularly into aquaculture water can not only reduce the occurrence of various diseases, but also provide calcium essential for aquaculture organisms, especially for crustacean aquaculture. Use method: select unweathered quicklime, clear pond disinfection with 150 - 200 kg per mu; disease control generally 5 - 9, 20 days or so once, water depth 1
