Correct Answer

(A) To get clean milk

Explanation

Solution: The major advantage of weaning cows is to get clean milk. Weaning is the process of switching an infant's diet from breast milk or formula to other foods and fluids.

[#172] Match the following columns Column-I (Nutrients) Column-II (Deficiency symptoms) a. Biotin 1. Loss in weight b. Cynoco - balamine 2. Slow growth c. Choline 3. Westing sickness d. Pantothenic acid 4. Goose stepping
Correct Answer

(C) a-2, b-3, c-1, d-4

Explanation

Solution: a. The deficiency of Biotin causes Slow growth. Biotin helps maintain hair growth and helps with inflammation. b. The deficiency of Cynocobalamine causes wasting sickness. Wasting syndrome refers to the process by which a debilitating disease causes muscle and fat tissue to "waste" away. c. The deficiency of Choline causes Loss in weight. Choline's efficient metabolism of fats has also been linked to a greater level of satiety, which, in turn, leads to a decreased consumption of calories, resulting in overall weight loss. d. The deficiency of Pantothenic acid causes Goose stepping. Pantothenic acid deficiency may develop in animals (particularly pigs) on rations of corn. Clinical signs include pelvic limb ataxia and a “goose-stepping” gait in which the stifle joints remain extended and the hips flex to lift the limbs off the ground.
