Answer 1

Correct option is (c) High-producing and pregnant cows

Easy explanation: Ruminants need a daily supply of all nutrients required for maintenance and production: milk, meat, growth and pregnancy. Quantitatively any of the types of a nutrient can limit performance levels, but the most likely to be in short supply are energy and protein; this is especially true for high and average yielding cows.
