In fact, pig farming was not taught before, but now it has become popular. What is the main purpose of using teaching slots? The summary is classified as 3 points.
First: The first priority of the teaching slot is “teachingâ€, which means that the church suckling pigs feed on non-breast milk feed.
In fact, from the point of view of suckling pigs' love for food, when using liquid feeds, micro-powder feeds are the second, and pelleted feeds are at the end; however, liquid feeds are basically not available at home and require special equipment for feeding, so it is difficult to practicalize; The feeding process is wasteful, and it is too powdery. Because of the reason of some raw materials, it is easy to stick your mouth and eating is also troublesome. Therefore, it is mostly based on granular materials. However, the pellets also have unfavorable factors, because the development of the suckling pigs begins, the gums are tender and the chewing muscles are weak, and they are not particularly fond of feeds with relatively high hardness and relatively coarse powder particles.
Therefore, it is expected that the chute material can be eaten by a large number of people. In terms of current material type and quality, it is not realistic, unless the material quality is greatly changed and human food technology is used for production, but the pig estimates Nothing such a blessing, and then the cost is not easy to bear.
Secondly, the amount of time spent on the teaching slot is in the “slotâ€, which means that the suckling pig is used to eating the feed in the “slotâ€.
What does this mean? Why should pigs get used to eating the feed in the tank? The purpose is to cultivate the intestinal tract and avoid invading the intestinal tract after forced weaning of high antigen feeds after weaning directly without weeds, seriously affecting the digestion and absorption of nutrient substances, and affecting the breeding efficiency.
To get suckling pigs accustomed to eating in the trough when they are hungry, it is necessary to use some means. The first is that the work of “teaching†is to be done well, and the second is that this material must be eaten by suckling pigs, easily digested, and the villi of the intestines will not be seriously damaged. The suckling pigs will love it and are accustomed to eating it.
Third: Promote extra growth in weight.
The above two factors are summarized. One of the teaching materials is to let suckling pigs “learn to eat†and the other is to “adapt the adaptability of suckling pig's intestine to non-sows' feedsâ€. If these are the only reasons for using the teaching material, It is not worthwhile. We need big pigs. Many years ago, we had only 10 pounds of weaned suckling pigs in the era of no promotion of the chute material and poor sow quality. And now, the average level is also close to 13 pounds, the normal level should be about 16 pounds, the high level of the point is also reached 18 pounds, the higher level should be about 20 pounds. This is the benefit of the combination of teaching materials and management levels.
Because they are used for young animals and have relatively low relative intake, most manufacturers who do not understand the truth have pushed their own teaching materials. They invariably focus their propaganda on the “material-to-meat ratioâ€, and most of them publicize their teaching channels. The ratio of material to meat is 0.8:1 or 1.1:1. It cannot be said that this propaganda is wrong. However, the fact is that in the normal pig farms, 10 pigs are fed with 1 pack of teaching materials. About an average of 4 pounds per suckling pig. Now even if we do not have to feed the slotted material, as long as the sow's lactation is normal, the 28-day weaning weight of the suckling pig can basically reach about 13 pounds. After feeding the corresponding amount of teaching material, the average pig farm has 16 pounds. About 18 pounds or so, about 20 pounds or so.
Then even if the factory material feed ratio, such as gaining 20-13 = 7 kg, only to eat 4 pounds taught trough material, then the grandiose of the public declared that "the ratio of my chute material to meat ratio of 0.6:1 you", in fact, this This kind of propaganda is relatively unreasonable. Because suckling pigs were born with 3 pounds of weight (weight N pounds during the experiment), after eating X days of milk and eating N days of teaching troughs, the body weight reached 20 pounds, which is the joint effect of the teaching material and milk, and not all of them According to merits, there are existing teaching slots.
In the current nutrition level of teaching materials, it is ridiculous to emphasize the material-to-meat ratio. If anyone really wants to test its feed ratio, there is a very simple way to use it to feed about 60 pounds of piglets. , see how much he can gain weight in 15 days. Because 60 pounds of piglet intestine has been shaped, the digestion and absorption of nutrients are relatively stable, and the measured value is the real value.
Note: The main raw material of the teaching material is mainly plasma protein powder, blood globulin powder, etc., together with some fully digested raw materials, it is easy to create an excellent teaching material. What is full digestion material? For example, glucose, which is fully digested, enters the intestine and can enter the energy cycle directly, basically consuming no additional energy for digestion. The corn pods you can not micro-powder can not be crushed directly into the metabolism, digest it is a lot of energy.
