10 month 26, WHO subordinate International Cancer Research Institute of fresh red meat, ranked second only to processing meat Products of "carcinogenic higher probability" food, causing panic among the public. In white meat, although chicken is eaten most, many people are deterred by hormones and antibiotic residues. In October 29th, the provincial animal husbandry bureau held the "face to face" of broiler production and consumption. Experts and scholars answered questions on the spot.
at the meeting, many consumers questioned, according to the growth rate of white feather chicken, usually more than 40 days can be released. Is this a hormone? "Hormones are too expensive, unless they are neurotic. Wang Baowei, a professor and PhD supervisor at Qingdao Agricultural University, said impolitely.
Wang Baowei explained that the fast growth rate of white feather chickens is determined by genetic breeding, nutrition and environment, in which the factors of genetics and breeding can account for 40%. "Since the 80s of last century, we have begun to introduce fine varieties from abroad and make use of and improve local varieties in China." Wang Baowei indicated that the white feather chicken grew fast and the feed conversion rate was high, that is, the chicken introduced at that time. At present, China's yellow feather broilers, white feather broilers and meat hybrid chicken complement each other, of which the white feather chicken occupies 64% of the current market.
"at present, broilers do not have the ability to transgene, and the Internet is also a rumor about those chickens that are genetically modified." Wang Baowei said, "six wings" chicken and so on are all nonsense.
"broiler is easy to get sick. Will there be any pesticide or antibiotics in the chicken?" Many consumers have doubts about it. "Now, a large broiler breeding enterprise uses about 0.8 yuan for each chicken." Wang Baowei told reporters, "there is an enterprise boss told me that their goal is to reduce the use of drugs to about 0.5 yuan." Wang Baowei said that there are three main reasons for antibiotic residues in livestock and poultry products, which are the feed additives for livestock and poultry, antibiotics used in livestock and poultry diseases, and the abuse of antibiotics.
"with the change of breeding mode, the drug residues of broilers are obvious now." Wang Baowei said that the disease rate of broilers has also been decreasing gradually from heavy padding culture to online maintenance and then to cage farming. "Some antibiotics are allowed, some are not allowed." Wang Baowei said that feeding antibiotics play a very important role in preventing and controlling animal diseases, improving production efficiency and improving the quality of livestock and poultry, but some antibiotics should avoid the use of animals.
"the cost of drugs and antibiotics is higher than that of feed, and if overused will increase costs without any cost." The head of an enterprise at the conference told the reporter. Wang Baowei said that the application of enzymes and microecological preparations is gradually replacing antibiotics.
Wang Yueming, director of the poultry Institute of Shandong Academy of Agricultural Sciences, said that the processing methods of poultry products are single, and the common people are mainly chicken stewed chicken or fried chicken, and few roast chicken. "This requires us to make more efforts in the food processing discipline, to develop some chicken processing methods, so that the people can easily do some delicious chicken food, which can greatly improve the consumption of chicken."
