Seeking approval to dispose of animal trial samples.

Details:
The research team collected various tissue samples, blood, urine and/or faeces for some animal trials funded by the PGGRC.
The tissue and excreta samples are now a minimum of 8 years old and have likely deteriorated to the point where results from analyses would be compromised and are therefore of little if any value for publication or scientific purposes. In addition, the samples are for PG classes that have been either patented (PG2000, PG12000, PG17000) and/or dropped for consideration for development into methane inhibitors (PG4000, PG5000).
We are now seeking approval to dispose of the tissue and excreta samples in the tables attached. 
In addition, histology samples (stored in formalin) have been taken for most animal trials since 2019 from the rumens of affected animals (not all animals in each experiment). These have in most cases been analysed by veterinary pathologists and the results reported to the PGGRC or NZAGRC-AgriZero. We also seek approval to dispose of these samples (as they represent a health risk), but not samples relating to the current PG25000 class and its related classes. We will keep those for now.
