The purpose of using the teaching material is summarized as 3 points:
First: the first weight of the teaching material is “teachingâ€, which means that the church suckling pigs feed non-breast feed.
In fact, from the perspective of suckling pigs, when the liquid feed is the first, the micro-powder feed is the second, and the pellet feed is the end; but the liquid feed is basically not available in China and needs special equipment for feeding, so it is difficult to be practical; The feeding process is wasteful, and it is too fine. Because of some raw materials, it is easy to stick to the mouth and it is troublesome to eat. Therefore, most of them are mainly granular materials. However, the pellets also have disadvantages, because the development of suckling pigs, the gums are tender and the muscles of the chewing muscles are weak, and the feeds with relatively high hardness and coarse powder particles are not very popular.
Therefore, it is not realistic to expect that the material can be eaten in large quantities in the current material type and quality. Unless the quality of the material is changed, the technology of human food is used for production, but the pig estimate Not so good, and the cost is not easy to bear.
Second: the weight of the teaching tank is heavy in the “slotâ€, which means that the suckling pig is used to eating the feed in the “tankâ€.
What does this mean? Why do you want piglets to get used to eating the feed in the tank? The purpose is to cultivate the intestines, avoiding the intestinal damage caused by forced feeding of high antigen feed after direct weaning in the intestines, which seriously affects the digestion and absorption of nutrients and affects the breeding benefits.
Then it is necessary to let the suckling pigs get used to the food in the trough when they are used to being hungry. First of all, the work of "teaching" should be done well. Secondly, this material must make the suckling pigs love to eat, easy to digest, and the intestinal fluff will not be seriously damaged. The suckling pig will fall in love with it and get used to eating it.
Third: promote extra growth in weight.
To summarize the above two factors, one is to let the suckling pigs “learn to eat†and the other is to “cultivate the intestines of the suckling pigs to adapt to the feed of the non-sowsâ€. It is not very cost-effective, we need big suckling pigs. Many years ago, the teaching of troughs was not promoted and the quality of sows was not good. The weaned pigs were only about 10 kg. Now, the average level should be 13 pounds. The normal level should be around 16 pounds, the level high point should reach 18 pounds, and the higher level should be around 20 pounds. This is the result of a combination of teaching materials and management levels.
Because it is used for young animals, and relative to the amount of feed intake, most manufacturers who do not know the truth have pushed their own teaching materials, and the focus of the propaganda is on the "material-to-meat ratio", and most of them promote their own teachings. The ratio of material to meat is 0.8:1 or 1.1:1. It cannot be said that this kind of propaganda is wrong, but the fact is that a litter of piglets (10) in a normal pig farm is fed with 1 packet of trough. About 4 pounds of material is eaten per piglet. But even if you don't have to teach the trough to eat, as long as the sow's lactation is normal, the weaned pig's 28-day weaning weight can basically reach about 13 kg; and after eating the corresponding amount of teaching materials, the average farm has 16 kg. Left and right, the level of the high point reaches about 18 pounds, there are about 20 pounds.
Then the manufacturer even if the whole feed-to-meat ratio, such as gaining 20-13=7 kg, only eat 4 kg of the grooving material, then the arrogant foreign claim that "my sifting material is 0.6:1", in fact, this Propaganda is relatively unreasonable. Because the piglet was born with a weight of 3 kg (weight N kg during the test), after eating X-day milk and eating N-day teaching trough, the weight reached 20 kg, which is the joint effect of the teaching material and the milk, and can not all be The teaching materials are based on the work.
In the face of the current nutritional level of the teaching material, it is ridiculous to emphasize the meat-to-meat ratio. If anyone really wants to test its meat-to-meat ratio, there is a very simple way: use it to feed about 60 kg of piglets. See how much it can gain in 15 days. Because the 60-pound piglet has been shaped, the digestion and absorption of nutrients are relatively stable, and the measured value is the real value.
Note: The core raw materials of the teaching material are mainly plasma protein powder, blood globulin powder, etc., together with some fully digested raw materials, it is easy to build an excellent teaching material. What is full digestion raw material? For example, glucose, which is fully digested, can enter the energy cycle directly after entering the intestine, and basically does not consume extra energy for digestion. And corn glutinous rice, you can not crush the state of the ingredients directly into the metabolism, digestion of it is a lot of energy.
