1 What is the teaching material?
The teaching material is the feed product of the suckling pig stage, which is a special feed product containing high nutrient content from the stage of birth to the four-week age of the suckling pig, also called artificial milk, opening material and the like. It is the first feed in a pig's life.
2 The role of the teaching material
2.1 Shorten the suckling period of suckling pigs
The weaning time was reduced from the traditional 45-60d to 21-28d. In traditional weaning, the use of the teaching material can overcome the problem of decreased breast milk weight due to insufficient breast milk. But nowadays, the rapid development of breeding, breeding and feed technology, many farms often use weaning at 3-4 weeks of age, and the use of the teaching material can not only improve the weaning weight of suckling pigs, but also avoid the weaning stress of suckling pigs. To create a stable environment for growth.
2.2 Improve the efficiency of pig production
Since the lactation period of the suckling pig is shortened, the basic sow can shorten the breeding interval and increase from the original two years to 2.6 per year. At the same time, it increases the growth rate, reduces the time for slaughtering, reduces the chance of disease infection, and improves the utilization rate and labor productivity of pig facilities.
3 types of teaching materials
At present, the types of teaching materials used in the production of suckling pigs are mainly in the form of particles, broken, powder and liquid. In actual production, the top three are used most, and only a few large pig farms use liquid teaching materials.
4 How to choose to use the teaching material
4.1 Quality teaching materials should have the characteristics of
Evaluation of the teaching material generally refers to whether the feed intake and growth rate of the suckling pig continue to increase, and whether the diarrhea rate is reduced. Under the conditions of pig breeds and software and hardware management techniques, the suckling pigs after eating the feed material showed “like to eat, digest, and feed intakeâ€, especially after the transfer of the material to the next product. Within one week, the rate of nutritional diarrhea was less than 20%; the feed conversion rate was about 1.2; the average daily weight gain was over 250g; the feed intake was more than 300g. Therefore, people must pay attention to the choice of teaching materials. Practice has proved that the quality teaching material should have at least the following characteristics:
4.1.1 Suitable for digestion and nutrient absorption
The content of anti-nutritional factors and allergic factors in the feed trough is low, and the feed digestibility is high, which is the key to improving the feed intake of suckling pigs. The feed has a good performance after being digested and re-deposited. The daily gain of suckling pigs at this stage is of great significance to the whole process of commercial pigs.
4.1.2 Good palatability
Suckling pigs like to eat, and the feed intake is very large, so they can have good daily gain indicators.
4.1.3 comprehensive nutrition balance
The nutrients of various raw materials are different and the digestibility is also different. Therefore, it must be scientifically formulated and carefully prepared.
4.1.4 Low incidence of pigs
In particular, the incidence of diarrhea should be minimized. Indigestion feed, which enters the large intestine after passing through the small intestine, is a good medium for bacteria in the large intestine, leading to rapid propagation of bacteria in the large intestine, which is the main cause of diarrhea in suckling pigs. In the case of nutritional diarrhea, in addition to protein, electrolytes, vitamins, amino acids and other nutrients are also lost with "thin". Many feed companies attempted to solve diarrhea by adding antibiotics to their feed, which turned out to be futile.
4.1.5 no weaning stress phenomenon
The occurrence of weaning stress will cause the piglets to lose weight after weaning and the growth is stagnant. In order to restore the normal growth rate of pigs as soon as possible and make up for the loss of weaning stress, it is necessary to improve the feeding conditions by increasing the feeding of weaned pigs.
4.2 When purchasing the teaching material, you should choose the big manufacturer, brand product
In the past ten years, due to the rise and popularity of the teaching materials, it has brought good economic benefits to farmers. There are many brands of teaching materials on the market, and the quality and price are uneven. How to choose the correct material? Farmers must first understand and investigate manufacturers and brands. Be sure to use products with good reputation, high output, good quality and suitable price. This is because the manufacturer pays close attention to the following four points in the development and production of the teaching materials: First, the digestibility of raw materials is more important than the nutritional parameters; second, feed intake is the key factor; third is the selection of protein and carbohydrate raw materials. The fourth is to reduce nutritional sputum through scientific modulation. Simply put, the suckling pigs after feeding the teaching materials should realize “love, no diarrhea, and grow fastâ€.
to feed the teaching material
5.1 Mastering Time
The time of using the teaching material is from 7 days after birth of piglets to 14 days after weaning (weight 10kg); 7-14 days after delivery, a small amount of feeding every day, for feeding, 14d to 4-5 times per day before weaning, through These two stages ensure that the piglets can successfully feed the teaching trough, and gradually transition to the nursery material after 10-14 days after weaning.
5.2 Selection Method
The use of the teaching material is mainly used: free feeding and divided feeding. Free feeding is the regular addition of a sufficient amount of feed, and the residual contaminated feed should be removed in time for each addition. The fractional feeding is 1d 4-6 meals, so you can do less feeding.
When feeding the teaching material in the early stage, you can feed a few pellets when you are putting a health needle or a vaccination needle; apply it to the sow's teat after making a paste, and let the piglet eat it when you are breastfeeding; The proportion of 4..1 is adjusted into a paste-like filling; first, the piglets are supplemented with a little pellet, and then the breast milk is taken after a while.
The pig farm can choose the appropriate method according to its own management conditions, but it must be done from less to more and gradually increase the dosage. At the same time, add enough clean drinking water during the feeding. In actual production, the liquid feed is better than the wet mix, and the wet mix is ​​fed better than the pellet.
6 Note
1 bagged feed should be tightly tightened after opening and taking out the package. The general packaging is mostly 5-20kg, and the shelf life is generally 45-60d to prevent deterioration due to moisture absorption. 2 Keep the trough and the environment to prevent the feed from being polluted. 3 When feeding, ensure that piglets can drink clean drinking water. 4 Less feeding, and gradually transitioning feed. 5 pay attention to keep the piglets warm.
