Cooperative pig
Commonly known as Heicuo Pig, Mountain Pig
The variety source center is located in the areas of cooperation, Zhayou, Bula, Meiwu and Jiamuguan in Xiahe County, Gannan Tibetan Autonomous Prefecture, Gansu Province, and is also distributed in the semi-agricultural and semi-pastoral areas of Luqu, Tieni and Diebu counties at an altitude of about 3000m.
The coat of Hezuo pig is mostly black, and the belly, limbs and tail tip are white. Piglets often have brown and yellow vertical stripes, which gradually fade with age, and the stripes disappear after 3 ~ 4 months old. The head is narrow and tapered, canine teeth are well developed, ears are small and erect, and there are no obvious wrinkles on the forehead; the neck and body are short; the chest is narrow; the waist is straight or slightly raised; the hindquarters are slightly higher than the forequarters; the buttocks are tilted, the limbs are strong, and the hooves are small and firm; nipples are usually 5 pairs. Hezuo pigs matured earlier, boars were 3 ~ 4 months old and sows were 4 ~ 5 months old. The litter size of first-born sows is 2, and that of post-parturient sows is 4-7, as many as 8-10. Cooperative pigs are mostly raised by grazing, one-year-old weight 25kg, two-year-old can reach 40kg, such as grazing and house feeding combined with one-year-old body weight can reach more than 40kg, slaughtering rate of 65%, delicious meat.

Biogas is used to incubate chickens
Biogas incubation has the advantages of simple operation, safety and reliability, high hatching rate, reducing cost and so on. Due to the small capacity of household biogas digester, this technology is very suitable for small-scale (less than 1000) farmers. The relevant technical parameters are listed later for reference: 1 cubic meter of biogas can hatch 475 eggs, biogas incubator consumes 300.40 litres of gas per hour, the hatching rate of fertilized eggs is more than 90%, and the hatching rate of biogas is 5% 15% higher than that of electricity and oil. and there is no worry of power outage, saving 3 kilograms of fuel for every 100 eggs hatched.

Prevention and treatment of Infectious serous peritonitis in Duck
Duck infectious serositis, also known as Pasteurella anatipestifer, is a chronic or acute septic infectious disease that infects ducklings (goslings). It is characterized by fibrinous pericarditis, pericarditis, pneumocystitis and arthritis. With the rapid development of duck industry and the expansion of trade in poultry products, the incidence of duck infectious serositis is increasing year by year, and it is easy to occur and difficult to treat, which has become one of the important diseases restricting the rapid development of duck industry. Controlling and eliminating the disease is of great significance to promote the rapid development of duck industry. Combined with the reality of my work, I would like to talk about the prevention of the disease.
