This is a good question. I think you might be mistaken in your question. I think you are referring to the commandments, which the first answerer has given to you. However, these commandments come later. The best we can do is say that Old Major planted the seed of the commandments.
Old Major did not give any commandments before he died. However, he did set the stage by making some points about the nature of their poor lot in life.
Old Major gathers the animals and clears his voice and says:
"Now, comrades, what is the nature of this life of ours? Let us face it: our lives are miserable, laborious, and short."
"Man is the only creature that consumes without producing. He does not give milk, he does not lay eggs, he is too weak to pull the plough, he cannot run fast enough to catch rabbits. Yet he is lord of all the animals."
The conclusion for Old Major is rebellion. The animal must do something now. He says:
Remove Man from the scene, and the root cause of hunger and overwork is abolished for ever.
So, although Old Major did not give an explicit commandment, he is the catalyst of what is to follow.
