testing with living subjects such as animals, plants, or cells. ex: fecal bag/ crate
in vitro

Is the artificial bag technique, ex: nylon bags

They are done mainly on steers because if it was done on heifers it would not only collect fecal matter but urine as well due to the position of the urethra
in fimo
samples derived from human and animal excrement and examined carefully
What ways can you research and measure digestibility
In vivo, In vitro, and In situ

uric acid
what are kittens very particular about and why?
