why do the goats panic when i lifted them up?

in 2016 when we went to a lodge in Jaldapara national park in india which is 50 km from Falakata there was a nearby village and there were goats too. i was a 15 yr old boy that time and tried to lift a baby goat but i touched it in such a way that it hurted its rib cage and it panicked and screamed mehhhhh. then i left it. i am sad because my grandpa can easily lift them and they never panic
