Answer 1

For animals 2-45kg:
RER = 30 x bodyweight(KG) + 70(Kcal)

For animals <2kg or >45kg:
RER = 70(Kcal) x bodyweight(KG)^0.75

Vitamin E - protects skin cells from oxidant damage
Vitamin C - helps heal wounds
Protein - hair is made up almost entirely of protein

Question 3

What is the impact of lack of protein or fats on skin and hair?

Answer 3

Hair is made up almost entirely of protein - lack of protein => hair may fall out or become dry, weak and brittle
