The words 'humane' and 'slaughter' put together, are what is known in the English language as an oxymoron, i.e. 2 words that contradict each other when put together. To use the term 'humane slaughter' is as nonsensical as to say 'humane rape', 'humane slavery', or 'humane holocaust'—regarding the latter point, some synonyms for 'slaughter' in the dictionary are 'bloodbath', 'massacre', and 'holocaust'... given that it does not make sense to use the term humane for any of those 3 words, neither can it make sense to say it for the word those synonyms derive from.
Ask yourself this question: is there a nice way to kill someone who doesn't want to die? Given that animals want to live, and value their lives as we value ours, there is no nice way to kill them.
In any case, anyone looking at the methods we use to kill farmed animals can see for themselves that it's not 'humane'. Whether the animal is stunned with a bolt gun or prongs, or whether it's by gas chamber, or whether they are killed via the Halal/Schechita method, these are not exactly methods we would use to euthanise even someone who did want to die.
Grass-fed, organic, free-range etc
Regardless of the nature of their lives before slaughter, farmed animals get sent to slaughter. There is a misconception that animals get to "live out their lives" and then get killed. Animals get killed as soon as their purpose is served, or as soon as they reach a profitable size, which is at a fraction of their potential lifespan. The very definition of grass-fed/organic/free-range animals is actually very loose and can vary wildly. It doesn't mean that the animals have any kind of quality of life necessarily, it just means the farm has to meet some arbitrary requirements to earn that title. That's not to say that every single farmer treats their animals dreadfully while they live - some actually do give their animals a fair standard of life before sending them to have their throats slit. But it's ignorant to think it's the norm in the first place.
The standard legal form of slaughter for animals is for them to be "stunned" and then have their throats slit. For chickens and pigs, the stunning is generally done with an electric shock, and for other animals a pneumatic bolt pistol projects a metal rod into their forehead. It is claimed that this renders the animal 100% unconscious, but if you actually look into the facts, slaughterhouse workers will admit that there is no way to verify that this is the case for every single animal, and indeed the process doesn't always work, isn't followed routinely, and indeed, the "stun" can wear off while the animal is being killed.
But regardless of the fashion of execution, there isn't a justification for taking the life. It is still taking the life of a sentient being, for your enjoyment ultimately. If somebody killed your companion animal, I doubt you'd say "that's fine because you did it humanely" as described above.
