In our 4-H group there is a large debate on which is better for kids that are bottle fed either by breeders choice or orphaned- cow's milk or milk replacer. Which do people use and why? Do some people mix the two? I am currently bottle feeding Athena and topping off Augustus after he has nursed. I do have a bag or milk replacer but have never used it. My children's 4-H group says we should use the replacer. Thoughts?
