Differences in chicken production at home and abroad

Introduction: the author found that the hardware facilities of chicken houses in domestic chicken farms are not worse than those in foreign countries, some of which are better than those in foreign countries, and the difference lies in the software of production management, especially in the "little things" in production According to my own opinions, the author lists out some differences in the breeding of chickens for the reference of colleagues in the chicken industry (1) disinfection of poultry farms outside the country generally does not have a disinfectant pool, and vehicles come in and out with spray sprays and disinfectant This not only saves medicine and water, but also has good disinfection effect There are disinfection pools at the gate of domestic chicken farms Not only the amount of disinfectant is large, but also most of them cannot be changed in time As a result, the disinfection pool has become a sewage pool, making the so-called "disinfection" formalism Many kinds of chicken farms in foreign countries add 3-5g polyformaldehyde (because formaldehyde is toxic, special tools must be used) to the padding of each egg box every week to disinfect the newly born eggs, so as to greatly reduce the possibility of egg shell spreading the disease This is rarely done in domestic chicken farms (2) drug use: developed countries have controlled or eliminated diseases such as pullorum and Mycoplasma gallisepticum With strict "biosafety" measures, there are few bacterial diseases, no need for drug treatment, but only in the prevention and control of coccidiosis, and the drug can be stopped as scheduled Therefore, there is basically no drug residue in poultry products The domestic broilers are fed with medicine almost every day from shelling out to marketing Not only antibiotics are added to the feed to promote growth, but also drugs are used to control chicken dysentery, mycoplasma, coccidiosis, etc Moreover, due to the emergence of drug-resistant strains, the larger the dosage is, the more serious the drug residues in the chicken exceed the standard (3) in the selection of roosters, in the process of raising and breeding roosters, second cocks shall generally be eliminated The foreign practice is: at dusk, the technician enters the chicken house, among the cocks standing on the high bed, selects the elimination objects according to the appearance, and sprays the iodoform on their feathers once selected On the second day, the breeder eliminated the cocks with yellow iodoform on their feathers The reason is: after the window of the chicken house is closed, the concentration of carbon dioxide and ammonia on the ground is higher than that on the high bed; the chicken standing on the ground is more comfortable than that on the slats on the high bed A good Rooster wants to stand comfortably on the ground A bad rooster is sensitive to carbon dioxide and ammonia He prefers to stand on a high bed if his feet are uncomfortable The practice of most kinds of chicken farms in China is: after technicians enter the chicken house in the daytime, they are eliminated subjectively according to the body shape and appearance of the rooster and lack of objective standards (4) hanging red cloth strips in the chicken house is a habit of pecking frequently It only takes about 2 hours for the house chickens to eat In order to meet the habit of chicken like to peck, we can hang several red cloth strips in the chicken house to let the chicken peck This can prevent the chicken from pecking Few domestic breeding farms do this, so the incidence of pecking addiction is relatively high, and only in the lack of nutrition to find reasons, ignoring the habits of chickens (5) often rake loose chickens with hard bedding on wet bedding for a long time, which is prone to leg disease In order to reduce the incidence of breeder leg disease, foreign breeder farms often rake the hard bedding loose (micro tractors are used in good conditions) to make the bedding soft and dry Most of the domestic chicken farms have ignored such trifles, so the incidence of leg disease of breeding chicken, especially for meat, is much higher than that of foreign countries (author:) share to feed Weibo share to:
