South Korean scientists have bred "biochemical pigs" to produce therapeutic agents for cerebral thrombosis.
South Korean scientists have successfully developed a biochemical pig (biopig) that produces a therapeutic agent for cerebral thrombosis (cerebral hemorrhage) through urine. South Korea's Rural Revitalization Agency said a few days ago: "the gene for the treatment of cerebral thrombosis (TPA) was injected into the fertilized eggs of pigs and successfully bred four pigs whose therapeutic substances can be excreted through milk and urine." South Korea has become the second country in the world after the United States to produce animals that can be genetically modified to treat cerebral thrombosis. The United States adopted transgenic technology in 1997.

Treatment of Chicken Gump-Paul Disease
1 the diseased chickens were isolated, each diseased chicken was injected with 2 ml antiserum intramuscularly, and each chicken without disease was treated with 1 ml emergency prevention. 2 0.05% oxytetracycline was added to the feed for 3 days to prevent secondary infection of bacterial diseases. (3) disinfect chickens with them. Disinfect thoroughly with 1 ∶ 1000 disinfectant and pay attention to feeding management at the same time.

Lean cattle grazing and fattening
Grazing fattening cattle is a fattening method based on the use of natural pastures. The grazing and fattening method has the advantages of low feeding cost, good fattening effect and easy to be popularized in the vast agricultural and pastoral areas. During the 150-day grazing and fattening period of lean cattle, the daily gain of local cattle was 0.5ml 0.7 kg, the daily gain of beef hybrid cattle was 0.8ml 1.2 kg, and the total weight gain of each cow was 100ml 180kg, which increased the economic benefit by 300Mel 400 yuan. The techniques of grazing and fattening cattle are introduced as follows. 1. Selection of fattening cattle

Mineral nutrition of pigs
It has been proved that there are more than 40 kinds of essential mineral elements in pigs, which can be divided into two categories: major elements and trace elements according to their content in pigs. Elements with a content of more than 50 mg / kg are major elements, which are mostly expressed by percentage content; elements less than 50 mg / kg are mostly represented by mg / kg. Pigs need at least 14 inorganic elements, including major elements calcium (Ca), phosphorus (P), sodium (Na), chlorine (Cl), potassium (K), sulfur (S), magnesium (Mg) and

Why is the pig fed with dry material?
Many pig practices have proved that pig feeding lean food will seriously affect digestion and absorption, resulting in dry feces, red eyes, reduced defecation times, intestinal peristalsis weakening, pig growth slow. Thus it can be seen that it is best for pigs to be fed with raw and dry powder, allow pigs to eat freely, and set up a trough for drinking water or heavy feed, with a feed-water ratio of 1 ∶ 1. This can prevent feed from freezing in winter and spoilage in summer, so that pigs can eat full and grow quickly.

What is the effect of carbohydrates on pigs
Carbohydrates, which are composed of carbon, hydrogen and oxygen, are the main components of plants, accounting for about 70%, 80% of all plant nutrients, and are the main source of energy in pig feed. Carbohydrates are converted into energy after a series of changes in pigs, providing heat for various life activities of pigs. After meeting the daily energy consumption, the remaining carbohydrates can be converted into fat and stored in pigs as energy reserves for use when hungry. Pig fat and suet are the reserves of this remaining energy.

Prevention and treatment of Clonorchis sinensis in pigs
1. The pathogen is caused by Clonorchis sinensis parasitic in the bile duct of the liver. In addition to pigs, dogs, cats and people can also be infected. Clonorchis sinensis is a small and transparent trematodes, 10-20 cm long and 2-5 mm wide. With the fecal ratio, the eggs were swallowed by the freshwater snail of the first intermediate host in the water, developed in the snail body and escaped as cercariae. Cercariae enter the body of the second intermediate main freshwater fish to form metacercariae, and the final host (pigs, etc.) is infected by eating undercooked fish containing metacercariae. In the pig small intestine, the metacercaria wall membrane is eliminated.

Technical measures for raising eggs
Chickens transferred to breeding house at 7 weeks of age began to enter the breeding stage, the success of this stage of breeding, to a great extent, determine the physical maturity and laying performance of laying hens, so to cultivate high-yield reserve layers that meet the requirements of the breed, the key link is to do a good job in breeding chicken feeding management. First, do a good job in the disinfection of the internal and external environment of the chicken house to create a safer living environment for the chickens. Many diseases in the laying hen farm are caused by horizontal transmission. Therefore, through the disinfection of the chicken house, the surrounding environment and the chicken body,

Pig food plus seasoning has a good fattening effect.
The taste of pigs is well developed, and there are as many as 15000 taste cells in the mouth. Adding seasoning (seasoning) to feed can promote the secretion of salivary glands, gastric glands and pancreas, increase food intake and promote growth and development. At present, there are the following kinds of seasonings: sweet seasoning in the diet of fattening pigs per kilogram, adding 0.05 grams of saccharin can increase the daily gain of pigs by 6.4% and reduce feed consumption by about 5%. The addition of 60ppm saccharin to the diet of lactating sows can prevent anorexia and excess during lactation.

Key points of raising piglets in spring
Sows are mated and conceived from October to November, and the piglets from February to March next year are called spring piglets, and in some places they are also called December piglets. Better economic benefits can be obtained by choosing to raise spring piglets. Because the conception rate of sows is high from October to November, the external temperature is low in the later stage of pregnancy, the appetite of sows is strong, the embryos can get rich nutrition, and the weight and survival rate of piglets are very high. In addition, because the sows have a strong appetite, more milk and good milk quality, the piglets are strong, weaning is significant, and the corresponding weight gain is fast.

Vitamin d deficiency, calcium and phosphorus metabolism disorders in geese
Vitamin D (VD) deficiency or calcium and phosphorus deficiency as well as calcium and phosphating disorders can cause osteoporosis, rickets in young geese or osteomalacia in adult geese. The disease is a nutritional bone disease, which can occur in geese of different ages. Clinically, it is often found in 3-week-old goslings. The main manifestations are growth stagnation, bone deformation, limb weakness, soft feet and paralysis. When the adult goose is sick, the number of eggs is reduced or soft-shell eggs are laid. In addition, the disease can also induce other diseases, often causing certain economic losses to the goose industry. 1. Disease

Matters needing attention when chicken is mixed with full-price feed
1. Make full use of local feed resources due to different crop varieties cultivated in different places, the types of feed are also different. In the spirit of adapting measures to local conditions and using local materials, we should make full use of local feed resources, especially those with low prices. In this way, the intermediate links can be reduced, the freight required for grain relocation can be reduced, and the source of feed can also be guaranteed. According to the survey, this measure alone can reduce feed costs by 3% and 5%. It is one of the effective measures to improve the economic benefit of raising chickens. 2. Raw materials
