Teaching materials, industry people can be said to be familiar. Before the sow material was not noticed, the teaching material was hot in the pig industry. From the technical point of view, the feeding stage, or the psychological level of the farmer, the teaching material has almost become a pen of expressiveness, and everyone is using it. The field is feeding. The teaching material is really such a god? With the development of the feed industry, the mysterious veil of the teaching material is unveiled layer by layer, people's enthusiasm is gradually cooled, and various problems appear day by day.
Around 2010, there was a new way of using the material, that is, wet mix, which is often referred to as porridge or milk powder. It was once popular in the industry, and major manufacturers competed for trials and innovations, but suddenly When the cold wind came, suddenly, the liquid material disappeared.
The phenomenon that the liquid suckling pig comes quickly and goes fast is closely related to some characteristics in the application. The author analyzes the reasons for the "tornado" effect of the liquid suckling pig material as follows:
Feeding method
The first generation of liquid suckling pig material is still powdery in the form of feed. When using it, a certain proportion of water needs to be added. What are the disadvantages of this feeding method?
First of all, the requirements for water resources are high. The water required for the mixing must be clean deep well water or warm boiled water. If the water is not clean, it will easily cause piglet diseases. Secondly, the storage is inconvenient, and the wet mix needs to be mixed. For example, if there are too many disposable ingredients, it is easy to spoil and spoil, causing bacteria, causing waste and piglet diseases. Third, in the feeding stage, the feed intake is low, and the daily feeding amount needs to be strictly controlled. Breeders must have a strong sense of responsibility to ensure that each piglet is fed.
Feeding stage
As we all know, the use stage of the teaching material is generally 7 to 10 days after the birth of the piglet and 7 to 10 days after the weaning, and the approximate period is 21 to 28 days. The traditional liquid material completely inherits this feature, the cycle is long, the feeding is inconvenient, and Caused a series of associated problems, such as material costs, labor costs, facility costs.
Feed quality
The quality of liquid feed on the market is uneven, and the composition varies greatly. For example, the composition and content of oil and molasses in liquid feed vary with the production batch and manufacturer, which also causes liquidity. The feeding effect of suckling pigs was significantly different, which did not achieve the expected results.
Feeding equipment
Given the different nature of different liquid piglets, each liquid piglet feed is slightly different. For example, some liquid formula products require separate liquid addition systems for each liquid material and special piping and silos, which are relatively expensive and time consuming.
Feeding cost
Some people compare the feed of pelleted pigs to the biscuits of human consumption from the perspective of diet. However, in terms of animal welfare, liquid materials should be more suitable for pigs than dry powders or pellets. The thrill of this! For this reason, liquid materials have extremely high requirements on feeding methods, feeding equipment and feeding personnel, etc., which invisibly increases the entire breeding cost, resulting in the acceptance rate of the user, and the liquid material is difficult to revitalize.
It mainly includes the following aspects:
1. Selection of raw materials for fermented liquid feed: At present, there are many choices for the raw materials for fermenting liquid feed. There are significant differences in the feeding effects of different raw materials, and the best raw materials for fermented liquid feed are still inconclusive.
2, the choice of diet formula design: different water materials and different diet composition can affect the feeding effect of fermented liquid feed.
3. Selection of feeding devices: It has been reported that the design of the feeding trough and the position of the feeding trough in the pens may affect the feed conversion rate and daily gain of weaned piglets. Therefore, the selection and design of feeding devices must be given sufficient attention by pig producers.
4. Fermentation control of pH: The optimal pH condition for growth and reproduction of pathogenic microorganisms is about 7. When the pH is less than 5, the activity of digestive protease is the largest. Therefore, the pH of the fermented liquid feed in the trough should be controlled within 5, and the pH of 4.5 is preferred.
5. Fermentation control of temperature: Temperature plays an important role in controlling the fermentation of liquid feed and lowering its pH. Controlling the temperature of fermentation can promote fermentation, and avoid the cause of pigs caused by too low feed temperature in cold winter. Unnecessary stress, fermentation temperature is affected by many factors.
Postscript
Up to now, different types of liquid suckling pigs have been widely used in many countries such as the European Union, and have achieved remarkable results in preventing diarrhea, increased feed intake and daily gain in weaned piglets.
However, there are still some problems in practical applications. Although the research and development of liquid piglets is still in the early stage of exploration, liquid pig feed will undoubtedly become an ideal substitute for antibiotic growth factors as long as it solves the problems of fermentation control, effectiveness and economic benefits.
With the continuous improvement of production technology, liquid suckling pigs will be generally accepted by breeding producers, and with its unique characteristics, it plays an increasingly important role in livestock production.
