With the development of the modern pig industry, many pig breeds with excellent production performance have been introduced, which has greatly improved the pig production level in China, and the weaning pigs’ age at the weaning time has also been greatly advanced (the current large-scale pig farms mainly focus on 21- Weaning for 28 days, of course, must have a matching feeding management model. Under the requirement of high production performance, high-nutrition sucker feed is required to meet the purpose of breeding. The problem then follows: “The traditional nutritional formula, although able to meet the requirements of early weaning and diarrhea, does not provide a high growth rate.†And the industry’s effectiveness in using granulated or powdered pigs is always good. There are different arguments. This article analyzes whether the modern "high-grade sucker feed" should use powder or pellets.
The high-grade sucker pigs are accompanied by early weaning techniques and will be applied and promoted in China around the year 2000. This material is in line with the requirements for early weaning of modern pigs.
High-quality sucker pigs have the following characteristics:
1, good palatability, suckling pigs love to eat;
2, easy to digest, easy to absorb, no diarrhea;
3, high levels of nutrition, production speed, so that weaned pigs can be stable and rapid growth after weaning.
In order to meet the above requirements, from the point of view of formula design, in the general case, extruded puffed corn, puffed soybeans and other puffed basic materials will be used in the formula, and a large amount of whey powder, plasma protein powder and yeast extract will also be used. And other high-quality raw materials. Since these raw materials all have high cohesiveness, especially high whey powder, granulation is difficult. The difficulty is that the pellets produced are hard and do not meet the crisp and soft requirements of suckling pigs. The processing of the powder is relatively easy to achieve, as long as the corresponding raw materials are crushed to the required fineness, and then fully mixed can be achieved.
So why should you choose to feed the pigs?
First, the so-called pellets can send feed digestibility, palatability issues.
High-grade sucking pig powder has been used in the expansion of corn, extruded soybeans and other extruded basic materials, the use of the basic formula itself has a good palatability and digestibility, which is equivalent to the granulation granulation process, both sterilization and curing of raw materials, but also The use of a large amount of whey powder, plasma protein powder, and yeasts has a good lure and highly digestible raw materials, and since the nutrients of the raw materials can be well preserved in the processing process, the high-grade suckling pig powder is now very good. Palatability and digestibility. And now high-end sucker pigs are widely recognized by the market, which also proves this point.
Second, the so-called particulate materials reduce diarrhea
Regarding diarrhea, weaning diarrhea is a concern for farmers. The main cause of diarrhea is still the feed itself, not the disease. Most of them are nutritional diarrhea, that is, the feed cannot be fully digested by sucking pigs. Diarrhea caused.
Granules can reduce diarrhea mainly due to the fact that they are compared to traditional, uncured, low-grade sucker feeds; while modern high-quality sucker feeds are due to the maturation of basic raw materials and the use of large quantities of high-quality whey powder and immunoglobulin-rich plasma. Protein powder, etc., has overcome this problem of diarrhea. In addition, because the raw materials can be crushed more finely than the particles, the diarrhea problem of high-grade powders is basically solved.
Third, the granules are more economical
Regarding the feeding characteristics of suckling pigs, starting from 7 days, the sows were able to obtain enough nutrients because they had enough milk. Pigs feed on feeds only because they are curious about the shape, aroma, and sweet taste of the feed, and they don't actually eat; even if the feed pellets are not eaten by the pigs, the pigs really feed heavily. Time has only appeared after weaning. Therefore, the amount of feed that is tempted before weaning is relatively small, and there is a certain amount of waste both in terms of particles and powder. Therefore, the pellets do not necessarily save material.
Fourth, the disease caused by the use of powder more convenient
With the current swine industry, new diseases are emerging and mixed infections are becoming more common, making it more difficult to prevent diseases. In the actual breeding process, some farmers will properly add medicines and health care agents to prevent the disease according to their own conditions. For the addition of drugs, the powder is definitely more convenient than the pellets.
