Answer:
18.3 pounds
Step-by-step explanation:
We are given;
Weight of horse = 588 kg
Calories required by horse each day per kg = 0.0333 Megacalories = 0.0333 × 1000 KCal = 33.3 kcal/kg
Thus, calories used by the 588kg horse = 33.3 × 588 = 19580.4 kcal
Now, we are told the food provides 1070 kcal for each pound of food.
So, if 1070 kcal produces 1 pound,
Then, 19580.4 kcal will produce;
19580.4/1070 pounds = 18.3 pounds
The horse needs 1.8 pounds of food each day
Since the energy requirement is 0.0333 Megacalories (Mcal) each day for every kilogram (kg) it weighs.
For a 588 kg horse, the energy requirement is:
Energy requirement = 0.0333 Mcal/kg * 588 kg = 19.5804 Mcal
Since each pound of food provides 1070 kcal per pound, hence:
Number of food in pounds needed = 19.5804 Mcal/1070 kcal per pound
Number of food in pounds needed = 19.5804 * 10³ kcal/1070 kcal per pound
Number of food in pounds needed = 1.8 pounds
Hence the horse needs 1.8 pounds of food each day
