The highly pathogenic avian flu that has occurred in Asia since the end of 2003 has been directed at the most intimate friend of humans - poultry. Tens of millions of poultry were slaughtered and became human sacrifices to the virus. In the face of this sudden disaster, people can not help but ask: Is it really the best way to prevent the epidemic? How does the poultry industry bear this high risk? After the author visited the Zhengda Group's scientific farms, he had a clear answer. That is, safe poultry calls for scientific breeding. Statistics show that chickens infected with bird flu before and after the New Year are almost all free-range chickens. Science-raised chickens on modern standard farms are very difficult to infect bird flu. The reason why this is said is that modern farming techniques are safer and more reliable than traditional farming models. Due to the modernization of modern farm equipment, production automation. Automatic feed lines, water lines, automatic heating, ventilation, and cooling systems have reduced human-induced instability to a minimum. In addition, the modern farms are far away from the residential areas, and the farmland is fully enclosed. The poultry are all house-fed. The breeders must bathe and disinfect when entering the chicken farm. This self-breeding, all-in, all-out breeding method basically blocks The spread of epidemic bacteria. The main thing is that chickens have a strict immunization program during their growth so that they can eliminate the source of infection. Some people may worry that the construction of modern farms may result in the closure of a large number of free-range farms, resulting in a large number of farmers farmers unemployed. We may not count an account. Under the traditional model, one farmer can raise 1,000 chickens per batch. Under the scientific breeding model, a farmer can raise up to 100,000 chickens per batch. According to the five batches raised in one year, as long as 100 farmers can raise 50 million chickens each year to meet the requirements of a slaughterhouse. On the surface, thousands of farmers will be unemployed. However, the slaughter factory supporting such a farm needs to employ 8,000 workers, and the related industries driven by it will also generate 2,000 new jobs, and the number of employed people has actually increased significantly. The facts of the current bird flu show that the scientific farming model has the characteristics of “high input, high output, high returns, and low riskâ€, can prevent the spread of the disease, help farmers reduce the risk of breeding, and represents the development direction of modern aquaculture. It is of great significance to improve the quality of poultry products, smoothly cross the "green barriers" to exports, and solve the problem of "three rural issues" in China by expanding employment and increasing income.
