Ducks are a tonic to eat. In recent years, with the increase in the number of ducks, the consumer market for ducks has also been expanding year by year, which has greatly mobilized the enthusiasm of ducklings for the majority of farmers. Duck farming has become a major source of income for many farmers. Well, as a duck farmer, if you want to do a good job of duck breeding, the choice of ducklings is very important. Because the quality of ducklings will directly affect the breeding efficiency of duck farmers. Then we will specifically introduce the precautions for selecting ducklings to the farmers' friends. The first point is to choose the ducklings that are hatched by their parents. Instead of choosing ducks that are hatched by breeding ducks on the market, there are many types of ducks that are grown on the market with the commodity and the second generation of the commodity. Although its price is relatively low, its hatched ducklings are of poor quality. Mainly in the relatively slow growth rate, size uniformity is relatively poor, relatively high material and meat ratio, the cost is relatively high. Secondly, from the appearance of ducklings, there are still a lot of knowledge in the actual selection. This requires that you have considerable experience. The simplest thing is to look at five places: The first is to look at its eyes, whether the eyes can open normally, is not very god. And some ducklings if the parental nutrition is not good or hatching conditions are not good, the technology is not off, its eyes may be dim. Then it is to see if its mouth and limbs are ruddy and smooth. Then it is to look at its navel, if the normal duck, its navel protein egg yolk absorption is good, its navel should be very clean, no faeces and eggshell stained on it. Then, looking at its claws, the limbs of the normally hatched ducklings are very bright and there is no dehydration. In addition, the majority of duck farmers are concerned about the quality of ducklings, but also should care about the price of ducklings. Because this will directly affect your farming costs. In general, the market price of ducklings is constantly fluctuating during the year, but it is not without rules. The price of ducklings and the price of ducks are basically synchronized. The general situation of duck prices is relatively low in March and April. Generally, the price of ducks is high before the National Day of the Mid-Autumn Festival. Therefore, the price of ducks will be high one month ahead of schedule. This is a change throughout the whole year. It is suggested that the majority of duck farmers should pay more attention to the collection of market information when selecting ducklings. In general, if they live, When the duck market is good, some people will deliberately raise the price of duck seedlings. At this time, if you buy it, it will inevitably increase the breeding cost, and your aquaculture benefits will also decrease. On the contrary, if the price of the duck seedling you buy is less than one yuan each, then the quality of such a duck seedling can hardly be guaranteed. Therefore, the duck farmer's friends must take into account the quality factors and price factors of the ducklings when selecting ducklings. Try to be good and cheap, don't try to be cheap, buy low-quality ducklings, otherwise you will suffer.
The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. This chemical product does not require a production license for medicines, and can be produced in ordinary chemical plants. As long as it reaches a certain level, it can be used for the synthesis of medicines.
