RESEARCH AND DEVELOPEMENT

Everything we do is based on science and on proven methods. These matters are too important to be left for guessing and assuming. Which despite rules and regulations is quite common even today. Especially in emergency situations where the end trumps the means and farmers are left for themselves to solve it.

PROOF OF PRINCIPLE FOR STUNNING PIGS APPLYING NITROGEN ANOXIA IN HIGH EXPANSION FOAM

Four scientists from SLU, Swedish University of Agricultural Sciences and from RISE, Research Institutes of Sweden, published on the 25th of November 2020 (after four years of study) the proof of principle for stunning pigs applying nitrogen anoxia high expansion foam technology. The study shows that it could be a feasible method for humanely stunning pigs. Besides the effectiveness of the nitrogen, the study also shows that there was little, if any aversive behaviours among the pigs, towards the foam. Which gives evidence of many advantages over carbon dioxide, electrocution and other stunning methods.

POTENTIAL ALTERNATIVS TO HIGH CONCENTRATION CARBON DIOXIDE STUNNING OF PIGS

High concentrations of carbon dioxide have been known for decades to cause pain, fear and distress in pigs before loss of consciousness, and the stunning method is clearly assosiated with animal welfare concerns. This study reviewed the scientific literature to find recent developments or evaluations of alternative methods that could lead to the replacement of carbon dioxide for stunning of pigs. The research is done by Erik Sindhoj, Cecilia Lindahl and L.Bark at RISE Research Institutes of Sweden, Lotta Berg at SLU Swedish University of Agricultural Sciences and the study gives proof to the use of nitrogen anoxia captured in high expansion foam as a recommended alternative.

PROOF OF PRINCIPLE FOR STUNNING POULTRY APPLYING NITROGEN ANOXIA IN HIGH EXPANSION FOAM

In May 2013, the results of the assessment of the Anoxia Method were published in Poultry Science. The focus of the assessment was on the welfare implications for poultry of the use of high-expansion gas-filled foam as a potentially humane, emergency killing method. In laboratory trials, broiler chickens, adult laying hens, ducks, and turkeys were exposed to air-, N2-, or CO2-filled high expansion foam under standardized conditions. The main conclusions was that the anoxia high expansion foam method is fundamentally different from low expansion fire fighting foam, and that the method provides a humane, rapid and highly effective method of stunning.
