The story basically covers chapter 1 & 2 of the Toriko manga which is the Garragator encounter & being the first ever animated work of the series. Key differences include the usage of blood & animation performed by UFO Table (Fate/Zero). Aside from changes in voice actors & music, this pilot is very similar to its manga content.
Pilots usually serve as a rough draft with what the anime should more or less be, however in this case there was no anime to come from it at least not within the following year. This pilot was made in 2009 & it wasn't until 2011 where Toei began to adapt the series. While the tone featured in the pilot was a lot closer to it's manga, many fans ask "Why wasn't the anime done by UFO Table?" or "Why was the anime so watered down?"
I can only speculate on these questions with no real evidence to back up my claims, however I believe there's a very simple answer as to why Toriko didn't get animated by UFO Table. For starters noticed how there's a gap in between the pilot & the anime debut being 3 years as opposed to other pilots such as Hunter X Hunter & One Piece who had animes within a year of their pilot debut. One of the reasons may have been UFO Table still being relatively small at the time but the more concrete answer would be the manga as I feel the pilot simply served as gateway into purchasing the graphic novels. The biggest reason why i believe in this, is the amount of content that the manga had. When the pilot debuted, the Toriko manga only had an estimated 50 chapters (till the end of the Regal Mammoth Arc), thus meaning not much would be adapted. If anything, Toriko may have been a 13 episode series or luckily 26 seeing how Toei covers those chapters within 17 episodes. Another guess is that no company was willing to take a risk into adapting a manga that's been published for a year. Seeing how it was 2009, most mangas didn't usually get immediate treatment as opposed to now in 2014.
Overall, the pilot is okay feature where we see Toriko being gritty. Lastly,it's usually a common practice where animes aren't drawn by the same company who drew their pilots or contain various differences in the final product. Take HxH for example as the pilot was animated by Studio Pierrot while the anime is done Nippon Animation.
