When large groups of drugs are often used when a drug is required in a chicken farm, large groups of drugs are usually administered by adding a desired drug to drinking water or feed. We often hear that a few percent or more of a drug is added to feed or drinking water to treat a disease, but in actual production it is often not guaranteed that the bird does get an effective dose of the drug, thus failing to achieve the desired effect.
Chickens, like other animals, should be dosed based on their individual body weight. Although it is very simple to add calculated drugs to feed and drinking water, it is sometimes difficult to meet the individual needs of chickens because the concentration of these drugs is calculated based on the normal amount of water or feed intake of chickens, so this The breeding chicken is not very suitable for the period of restriction. For example, when a commercial broiler is fed at the age of 5 weeks, it can consume more than 120 grams of feed per day, while the feed intake of broilers of the same age is only half. In addition, if the 3.5 kg weight of the breeding hen after the peak period of the egg production is more than 160 grams, it is only half of the free feed intake. In this way, these breeders will not be able to get their expected drug dose.
When an outbreak occurs, the affected chickens stop eating or feed intake. In this way, if drugs are added to the feed, those chickens that are in urgent need of drug treatment will not get or get a small amount of drugs that are less than the effective dose. At the same time, the feeding time of breeding chickens is usually about half an hour in the breeding period, and only 1-4 hours in the laying period, so those chickens with weak and poor appetite cannot receive effective treatment.
Some people overcome this problem by using double-dosing methods. However, this will result in excessive feeding of healthy chickens, resulting in severe drug poisoning when the drugs used are more toxic (eg furazolidone and sulfonamides).
Therefore, the use of drinking water for breeding breeders is better than mixed feeding. First, drinking water can be restricted without any restrictions or without affecting the amount of feed intake. Second, most diseased chickens also drink water without appetite, although drinking water may be less. However, some drugs must be mixed in the feed, such as anticoccidial drugs or drugs for the treatment of chronic chicken cholera.
If it is necessary to administer the drug in the feed, the following factors must be taken into consideration when calculating the dose: an effective dose per kilogram of body weight, such as oxytetracycline 55 mg/kg body weight. The average weight of chickens. For example, the average weight of the breeding hen at the age of 19 weeks is 2 kg. Daily feed intake per bird. Such as: daily 95 grams of such oxytetracycline in the amount of feed should be: 55mg2kg/0.095kg=1158mg/kg or 1158g/ton feed.
The result calculated from the above example is that 1158 grams of terramycin pure powder should be added per ton of feed. Because the commercial drugs in the market usually contain only a certain percentage of pure drugs, they should be calculated correctly and adjusted accordingly. At the same time, since the calcium in feed can reduce the absorption and utilization of oxytetracycline, 13 kg of sodium sulfate per ton of feed can be added during the treatment to avoid the influence of calcium (the laying period is disabled). In this way, a well-calculated medication regimen will ensure that the birds take the correct dose of the drug, and the treatment results are much better than using the same regimen for all chickens under different conditions.
Pork is a very common meat in life, especially in China. Pork consumption is much higher than other meats and is the main source of meat. Pork tastes and tastes very good, it doesn't get tired when you eat it regularly, and it has a variety of practices. It can be delicious with a variety of ingredients.
Although the pork chop is made of pork, it has no fatty feeling at all, and it is particularly chewy. It is processed through many processes, not to fry or cook pork. The pork that is made out has a lot less oil, and the feeling of eating meat is particularly cool. The authentic pork chop uses the pig's hind leg meat. This part of the meat is mainly lean meat, and the fat is rare. It is more suitable for pork. breast
