How to breed pigs with excellent meat quality? Need to be managed and exercised like this
As we all know, pork is a must-eat meat product for people's lives. The market demand is large, but there are many people who breed pigs in China. How do we occupy a favorable market? In fact, the method is very simple, that is to breed a different pig, improve the quality of pork. Here are some tips on quality pig management. You can refer to it. It is understood that the relatively fat pigs are now unpopular. Many people, especially girls, do not eat fat meat, and now many people pay more attention to health for their health. Therefore, everyone likes to eat lean meat. Therefore, those pig farmers must find ways to make the pigs grow lean, of course, to make the pigs grow lean, not to say that the pigs are hungry, just like people lose weight, but to make the pigs strong, except To ensure that the pig's diet is nutritious and healthy, it is necessary to let the pigs exercise more. Of course, we must first prepare the pigsty. We must create a more comfortable environment for the pigs. The pigsty should not only be clean but also ventilated. Moreover, the pig must have a separate space because the pigs are more arched. Therefore, its door must be surrounded by a relatively strong fence. Another is that pigs always urinate in places where there is water. Therefore, we have to put some water in a place far away from the pig's trough, of course, we must do a good job of draining and urinating. Otherwise, the hygiene of the entire pigsty is difficult to do. When the place is ready, we must start picking the piglets. We must choose healthy and lively piglets so that the piglets can grow up healthily and become less sick. Moreover, piglets should be taken care of carefully. When the weather is hot, they should be washed with water. When the weather is cold, they should be padded in the pigsty. The food should be carefully prepared. They should be cooked and eaten. Don't eat cold food to prevent getting sick. Of course, after the pig grows up, it should be slightly better in terms of diet. Most people will feed with feed. Because of the large-scale farming, it is definitely not enough to eat food and vegetables. Of course, we can use sweet potato poles and leaves. It’s also a good thing to smash the boiled and mixed feed, and then the rice, and the pig is also a favorite. Moreover, don't look at the pigs who prefer dirty places, such as mud pits, but we must always keep their nests clean and tidy with water when the weather is hot, otherwise the pigsty will be stinky. Easy to breed bacteria. So every few weeks, it is best to kill them. Such pigs will be healthy and less sick. Because they are kept together, as long as one pig is sick, it is easy to infect other pigs, so it is necessary to ensure the health and safety of the pigsty. Of course, if there is a venue, when the weather is good, you should always drive these pigs out to activities, because only with more exercise, they can grow stronger. In fact, we usually rely on some small water for raising pigs. Pond, if you set up a special passage in the pigsty to the small pond, you can pick a fixed time every day, drive them along the special narrow passage to the pond, force them to jump, let them swim, everyone All know that swimming is the best way to exercise , so if the pig can swim for a while, then it will definitely grow stronger. Such pigs, not only have good meat quality, but also have less fat and are sure to be loved by everyone. When it comes to raising pigs, many of my friends say that pigs are not raised, and every household in rural areas is raising. What is difficult, it is not difficult to raise pigs, but pigs who want to breed high-quality meat still need to master certain skills. of. Otherwise how to seize the market opportunity. The above is the quality pig breeding management skills, we will quickly learn from it. Urine analyzer is an automated instrument for determining certain chemical components in urine. It is an important tool for automated urine inspection in medical laboratories. This instrument has the advantages of simple and fast operation. However, improper use of urine analyzers and many intermediate links and influencing factors directly affect the accuracy of automated analysis results, which will not only cause errors in experimental results, but even delay diagnosis. Therefore, operators are required to understand the principles, performance and precautions of automated instruments. And the knowledge of influencing factors and other aspects are fully understood, and the correct use of automated instruments can make the results obtained by the urine analyzer more reliable and accurate.

application
In the 1950s, a single dry chemical test strip method was used to measure protein and glucose in urine, and the changes in the color of the test strip were observed with the naked eye and compared with the standard plate to obtain the corresponding values. In the 1980s, due to the high development and widespread use of computer technology, automated urine analyzers also developed rapidly, gradually developing from semi-automatic to fully-automated. Urine analyzers are often divided into two categories according to the test items: â‘ 8-11 screening combined urine test strips mainly used for newly diagnosed patients and health examinations. The eight test items included protein, glucose, PH, ketone bodies, bilirubin, urobilinogen, red blood cells (occult blood) and nitrite; in addition to the above eight tests, urine leukocyte test was added to the nine test items. On the basis of 9 of the 10 urine analyzer testing items, the urine specific density test was added. 11 testing items have added vitamin C testing. â‘¡It is mainly used for the observation of the curative effect of the diagnosed diseases, such as the combination test strip of PH, protein and occult blood (red blood cells) for kidney disease; the combination test strip of PH, sugar and ketone body for diabetes; the combination of bilirubin and urobilinogen for liver disease test tape.
principle
This type of instrument is generally controlled by a microcomputer, and the color change on the test strip is measured semi-quantitatively by using a spherical integrator to receive dual-wavelength reflected light. There are several reagent pads containing various reagents on the reagent strip, each of which reacts independently with the corresponding components in the urine, and displays different colors. The depth of the color is proportional to a certain component in the urine, and there is another in the reagent strip" Compensation pad", as the urine background color, compensates for the errors caused by colored urine and instrument changes.
Put the reagent strip with urine adsorbed in the colorimetric tank of the instrument, and the various reagent pads that have produced chemical reactions on the reagent strip are illuminated by the light source, and the reflected light is received by the spherical analyzer, and the photocell of the spherical analyzer is reflected. Irradiate with dual-wavelength light (measurement light passing through the filter and a reference light), and the selection of each wavelength is determined by the detection item.
The instrument automatically calculates the reflectance according to the following formula, and then compares it with the standard curve, and automatically finds and prints the corresponding results of various components. If the content of a certain component in the urine is high, the reflected light of the corresponding reagent pad is dark, otherwise it is strong.
Reflectance fraction: R(%)=Tm.Cs/TsCm×100%
In the formula, R(%) is the reflectivity; Tm is the reflection intensity of the reagent pad to the measurement wavelength; Ts is the reflection intensity of the reagent pad to the reference wavelength; Cm is the reflection intensity of the calibration pad to the measurement defect length; Cs is the calibration pair. Reflection intensity at the reference wavelength.
