How did the introduction of animals in the columbian exchange affect many native american cultures

Natives were able to use the animals from the columbian exchange to help them in many ways. 
Some examples of these were: horses, cattle, sheep, goats, and pigs.

horses: helped Indians move from place to place faster
cattle: helped Indians in farming, gave them beef (meat) 
sheep: gave Indians wool, gave them lamb (meat)
Goats: Milk, meat,
Pigs:  Pork

hope this helps
