Deworming sows is important, and pig farmers must not ignore it
As is well known, mycotoxins are a major killer of sows. One important reason why sows are difficult to raise, prone to many problems and diseases, and low in productivity is the impact of mycotoxins. However, many pig farming friends lack a correct understanding of deworming sows, and the measures they take are merely superficial efforts.
Problem One: Sows are large in size and have strong resistance, so there is no need for deworming!
Some pig farming friends say: “Sows are large in size and have strong resistance, so a little mold does not affect them and there is no need for deworming. I even sweep up the feed scattered on the ground and give it to the sows to eat.” This way of thinking is wrong. The production tasks of sows are very heavy. Special reproductive physiological activities such as estrus, mating, pregnancy, farrowing, and lactation are all strong stressors to the sow's body, causing damage to the mother and leading to reduced resistance; in addition, some pig farms use gestation crates for sows and add medication for long periods, further reducing sow resistance. Therefore, if sows are still not dewormed, under the above circumstances the sow's constitution will be on the verge of collapse, leading to the occurrence of various problems, and no matter how high the market price is, the pig farm will find it difficult to be profitable.
Problem Two: The raw materials I buy are good, so there is no need for deworming!
Some pig farming friends say: “The corn I buy is all good corn, more expensive than what others buy, so there is no mold problem.” This way of thinking is also wrong. High-quality corn indeed has a somewhat lower rate of exceeding mycotoxin detection limits than ordinary corn, but that does not mean there is no mold contamination. According to monthly sampling inspections by professional institutions, the detection rate of mycotoxins in corn, bran, self-mixed feed, and complete feed is all 100%. Although the rate of exceeding limits is not 100%, we know that toxins accumulate. Sows have a long breeding cycle and a large feed intake. One or two days, one or two weeks may have little effect on the pigs, but one or two months, one or two years will have a big effect, which leads to the problems many friends report, such as “I raised them the same way before and there was no problem, so why did they not come into estrus this time?” and so on. Therefore, even if the raw materials are good, deworming work must still be done well.
Problem Three: I have added a mold remover, so the mycotoxin problem has already been solved!
Some pig farming friends say: “Mycotoxins really do have a big impact on pigs, so I use the most expensive mold remover or an imported mold remover, and there is definitely no problem with mycotoxins!” This way of thinking is also incorrect. There is currently no national standard for mold removers, their effects are not easy to evaluate intuitively, and the market is very chaotic. At present, most mold removers on the market mainly contain montmorillonite, which adsorbs toxins mainly through its porous structure and ionic polarity, but at the same time it also adsorbs some nutrients; some higher-end mold removers also add yeast cell wall extracts, modified aluminosilicate crystals, and the like, using composite technology to address mycotoxins, with relatively better effects. However, no matter what the ingredients are or how many ingredients are combined, all current mold removers cannot adsorb mycotoxins 100%; they can only relatively reduce the harm of mycotoxins and cannot completely solve the mycotoxin problem. Therefore, no matter how good the mold remover is, please do not rely on it excessively.
>> So, how can the impact of mycotoxins on sows be properly addressed?
1、Strictly select and store raw materials, and do a good job of basic processing
First, the most important thing is still to strictly control raw material quality. Choose good-quality raw materials. When purchasing raw materials such as corn, pay attention to key indicators such as moisture content and mold rate. When storing, pay attention to storage conditions (temperature and humidity) and storage time. Before crushing corn, it is best to use equipment such as a corn cleaning machine to screen and remove impurities. In general, select raw materials for use, and resolutely do not use moldy raw materials. This is the most fundamental measure to reduce the impact of mycotoxins.
2、Correctly view and select mold removers
Second, you can choose some mold removers with a relatively good reputation on the market, but mold removers mainly rely on the principle of adsorption, so you cannot rely excessively on them.
