With Jub's help, that negates the Animal Handling check's disadvantage, allowing Brutrumukk to cruise on in with a roll of 18.
....
Well, that is a success.
However, I will say that Jub's Help includes informing Brutrumukk that the owlbear is a carnivore. The owlbear eats meat...A lot of meat.
So, while the Owlbear would eat jerky in the rations, it would ignore the rest of the rations and look for more meat.
