there was a lot of little bits of info today, so instead of ranting about all of it and wasting my time, i'll just say refer to "comparison of introduced and native pasture species/pastures"
its a big table with 3 columns.
the general geist is that introduced pastures are more tasty, digestible, nutritious and contain more energy, however native plants are more resistant to weeds, extreme climate and dont necessarily need re-sowing after grazing. however they dont withstand heavy grazing as well as introduced species do.
overall native species are more sustainable coz they dont cost as much and you dont need to pay for things to protect them from weeds and climate and such as much.
one last thing we did was seeing the relationsb etween pasture quality and animal production quality.
eg. irrigating pasture will maximize photosynthesis, thus growth & nutrient uptake, making more nutritious and delicious plants, and so cows produce more milk
