Spring time! Especially in WA

20
Q

What are factors of determining hay quality? (8)

21
Q

T/F: A forage only diet will be able to maintain a horses weight and essential nutrients

A

False.
A forage diet WILL be able to maintain their weight, but will LACK in trace minerals. So you should ass supplements to their diet.

22
Q

What are common trace minerals that would need to be supplemented in a forage only diet? (3)

A

Q

What are “brood mares”?

A

Horses producing or nursing offspring

Q

A

False!
Mares should be given grain to increase their calorie intake. Now is the time to up those calories.

26
Q

T/F: During lactation, high energy, protein, Ca, & Ph is necessary. The goal is to maintain BCS this way.
