40 out of 600 piglets collapsed - then the reason was discovered.
In one farm, a difficult supply situation on one acid product caused it to be replaced with another.
The mineral supplier did not seem to be aware that the chloride content would be in deficit. The pigs noticed it very fast, and productivity took a decent dive until the bug was corrected.
CHLORIDE WAS FORGED
Since late 2017, the acid product calcium formate has been difficult to obtain for some mineral companies. Therefore, in some cases it was replaced with another acid product sodium formate.
Sodium formate, in addition to the acid action, also supplies the mineral sodium. Sodium is usually added via salt (sodium chloride), so the salt content will decrease when sodium formate is also added.
This is where the problem arises: salt is also a major source of chloride. When the salt content is reduced, the chloride content falls below the norm and the pigs are in deficit.
Why was this issue not taken into account - can you wonder?
The short answer is enough: pure forgetting, or underestimating the importance of chloride for pig productivity. Perhaps also the practical fact that the admixture percentage of the mineral mixture must be changed if the chloride content is to be maintained. It is easier to continue unchanged.
The production results began to go go slowly downhill
In the herd of breeding and pig production, the pigs had been stable for a long period.
The mineral supplier announced a change in acid product from calcium formate to sodium formate with unchanged admixture percentage.
After that, the climate shed began to "quietly" just as quietly. Symptoms became more and more evident over a four-month period, regardless of what was being attempted by measures.
* The weight dropped 2-3 kg
* 30-40 pigs (out of 600) "collapsed" and fall behind
* 0.4 percent higher mortality
* Time consumption for sorting "exploded" (2-3 hours compared to the previous 0.5 hour)
* Purchased starter mix worked well (consumption doubled)
* Homemade feed 9-30 kg works poorly
LIKE TO TURN A HAND
When the chloride subfamily error was discovered, a new mineral mixture (and new acid product) quickly came into place.
According to the farmer, the departure weight was back to normal in three to four weeks and the pigs thrive completely as before.
The lesson must be that you should check the content of chloride if sodium formate is included in your mineral mixture.
Of course there can be many reason why the pigs collapse
