Potential threats to our reputation

I believe strongly that the potential risks to human and animal health and the risk to our industry reputation of altering the rumen of our ruminants through methane vaccines, methane boluses, feed additives and GM grasses is of such huge consequence that all NZ farmers should get a say in this decision.

NZ farmers will be asked to spend time and money on products that will deliver no tangible benefit to their farming systems whatsoever, except perhaps giving them a 'license to farm' in the sense of 'being seen to be reducing ruminant emissions'. Reductions in global temperatures due to these measures will be impossible to measure because they are totally insignificant.

What I find really concerning is that Beef + Lamb and Federated Farmers were very quick to embrace discussions around GMO grasses, methane vaccines, feed additives, methane boluses and any other 'biotech tool' that alters the rumen of the gut without seeking clearance from farmers. The subject of genetic modification and/or gene editing can be an emotive and polarising topic. Many times people have an opinion that is based on very little scientific understanding or they may resort to 'group think' without knowing what they are truly supporting.

Regarding methane vaccines: while vaccination for unwanted diseases is a common practice, an additional vaccination that has no benefits to the animal and that targets a naturally occurring rumen organism could well face consumer, regulatory and animal welfare hurdles.

I urge great caution on this journey of fast-tracked novel biotechnology tools.

There is huge risk for very little gain. Advancing biotechnology in the name of climate change is only ever going to serve those with commercial interests in the biotech companies. Trying to trim millionths or even thousandths of a degree warming, which is a temperature difference virtually impossible to measure, is both illogical and unjustifiable. The benefits are an expensive illusion.
