An egg farmer is experimetnting with different feed rations with the aim of increasing his production whilst reducing the cost of the feed per egg produced. The data from two feeding experiments is given below.

Which feed composition give the least cost per egg produced ?

Options

A. `{:("Protein (concentration (%)",,"Total vitamin level" (mg//kg)),(16,,100):}`
B. `{:("Protein (concentration (%)",,"Total vitamin level" (mg//kg)),(14,,50):}`
C. `{:("Protein (concentration (%)",,"Total vitamin level" (mg//kg)),(14,,100):}`
D. `{:("Protein (concentration (%)",,"Total vitamin level" (mg//kg)),(14,,150):}`

Answer

D

Explanation

In experiment 1, cost per egg produced from different protein concentrations can be calculated as follows:
Cost per egg `= ("Cost of feed per 100 hens per day")/("Number of eggs per 100 hens per day")`
The calculations show that the cost per egg for different protein concentrations is `0.085, 0.100, 0.100, 0.100, 0.109` and `0.112` respectively.
Similarly in experiment 2, cost per egg is found to be `0.114, 0.103, 0.100, 0.097, 0.094, 0.097` and `0.100` respectively with increased vitamin level. Hence, on analysing the given experimental results, it becomes clear that least cost per egg in incurred in feed with `10%` protein concentration and vitamin level at `100 mg//kg` but out of the given options, option (d) i.e., feed ration with `14%` protein concentration and `150 mg//kg` vitamin level gives the least cost per egg i.e., `0.094`.
