Moderator: On behalf of the food and drink channels Sohu Sohu welcome to participate in the four to visit our forum, first of all ask each of you to play with Sohu to greet friends.
Cheng Guang Chao: Hello everybody!
Moderator (Ma Chuang): Mr. Cheng Guangchao genetically from the Chinese Academy of Sciences Director of Research, Cai Huiyi feed from the director of the Chinese Academy of Agricultural Sciences, Miss Chen Fang from China Agricultural University, Institute of Food Science and Nutrition.
I am a horse break from the China Animal Husbandry Association. We understand that many consumers of technology for the development of the poultry industry is not very understanding, for example, 40 days for broilers which can grow to two kilograms of doubt to the fact that that you do something in this respect Cheng introduced.
Cheng Guang Chao: I start with two simple data, since the reform and opening up our country by the rapid development of livestock, the current amount of meat in our country with the total eggs have been ranking first in the world, the total amount of poultry meat is the second, China's livestock industry can be said that the international community has a pivotal position. the total meat production in 2005 according to figures released by the Ministry of Agriculture, our country is 77,431,000 tons, the U.S. is 39,305,000 tons, poultry production was 14.643 million tons in China, the United States is 18,506,000 tons, egg production was 28.795 million tons in China, the United States is 5,329,600 tons. These figures show that our country has made animal husbandry great progress, per capita consumption is not explained in detail, because our country is relatively large, large population and spending habits are not exactly the same with the foreign, if per capita consumption is, we per-capita figures are not so high.
The second set of figures, the current international, including domestic chickens, laying hens have reached a very high level of production, broiler-type chicken eggs soon reach 2 kg for 40 days, 72 days or 45 days up to 2.5 kg, feed conversion is 1.8:1 or 1.65:1,1.8 1.65 pounds of feed or feed can grow a pound of meat is the meat of the chicken more, listed 1.2m3 kg body weight, time to market is 56,70,90,105,120 days, more than 50 days to 100 days to achieve more than a kilogram, a little slower than the fast layer, but good meat quality. aspects of a chicken egg laying up to 330 years, total 21 kg of material to egg ratio of 2.6: 1, which is more advanced. our advanced a chicken farm for a year the average number of egg 280, 17 kg of total egg production, feed egg ratio 2.3:1.
two sets of figures shows that China's meat, eggs, laying hens reached a high level, mainly from the perspective of science and technology is now applied, chicken and other various scientific disciplines with respect, and today many experts to have engaged in food and nutrition, there are engaged in food production, There are disease control, and advanced science and technology used to achieve such a high chicken on a good level. I refer to the University of Edinburgh Professor WIENER constitute elements of productivity of livestock and poultry breeding one, one is nutritional, one is management, there is a health care, there is physiological or pharmacological regulation. These views of experts summarized according to a more specific figure is given, the proportion of breeding up to 45%, which is the contribution of nutrition, 25% m30% , disease prevention and control accounted for 15%, other including environmental control, production organization and management and even marketing strategies, advertising, etc. account for 10% m15%, the proportion of breeding large.
Moderator: Mr Cheng the teacher talked about the development and contribution in the production of which, feed accounts for 25% m30% the proportion of the following please tell us about Caisuo Zhang feed and feed additives in China the development of the basic situation.
Caihui Yi: first to find out the concept of , people eat something called food, animal feed, to eat something called, but we are talking about industrial production of feed is out after different animals, different production purposes and even for the different needs of the market specializes in the manufacture of special raw materials, feed a wide range, we usually refer to energy feed such as corn, wheat, called the supply of energy to feed some of it is protein feed, such as fish meal, plant protein, animal protein is the protein feed. there is a category including mineral feed, including dicalcium phosphate, ferrous sulfate, copper sulfate, and so are minerals. The fourth most vitamins such as vitamin ABCD the entire series. total includes four major components together, constitute only about the animals we eat feed . feed, which divided the full price of feed, refers to a scientific formula, in accordance with their own nutritional needs of animals, designed a special feed produced is called the full price of feed, so we usually talk about is the feed. in the feed some of the above named concentrated feed, the so-called concentrated feed means to feed the energy removed and only gave birth to a protein, minerals, vitamins, composed of three parts, it's probably the ratio should be around the 15% m20%. Beyond that is pre-mixed feed, we referred to as premix, mineral and vitamin premix mainly referring to drug additives as well as some with the premix, which accounts for the general in the feed of about 0.5% m1%. the last upward of feed additives, feed additives is the process in which the feed to add it for human or animal nutritional needs of a small amount of additives necessary for disease prevention, many different types of additives, and we just talked about, including a dozen vitamins, ten kinds of trace elements, There are defensive additives to promote growth, but also to some extent is treatment with the drug class of additives. a wide variety of additives, it is now most concerned with the safety of feed additives may be directly related to that of antibiotics, hormones and stimulants so people think that this type of poultry meat or eggs directly affect the quality of the product material.
Moderator: We have previously heard the reaction of many consumers in this regard, they believe can grow up to 40 days broiler more than two kilograms, which they believe is the feed added hormones, so there is such a fast growth, many children are precocious problem boils down to this issue because the chickens ate feed with hormones, but they did eat, the residual problems caused by hormone chicken, which is you please clarify how the matter in the end.
Caihui Yi: We talked about a phenomenon, why can a long 42 days to 2.5 kg or more than 30 days of the time, a few factors, Professor Cheng has just talked about the contribution of poultry production, the species is first and foremost, we have different breeds is not the same growth rate, local varieties of domestic chicken relatively slow growth rate, slaughter time 60m100 days ranging from yellow chicken, the chicken is a kind of hybrid of the slow growth of domestic species, all species rely on this slow growth can not meet the needs of domestic poultry products. should be said that nearly two decades last ten years we will introduce a large number foreign varieties, our society often described as fast as the chicken, because it grows fast, short length of 35 days m42 days to 5 pounds or so will be able to.
addition to variety, the second factor is that we feeding the environment and keeping the way, the chicken rearing environment for good, then the chicken is also relatively long fast.
third factor, there is no interference from the chicken disease is also growing fast.
