Question

Carefully read the following information to answer the question -

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

Experiment 1

Protein concentration in feed (%)	10	11	12	13	14	15	16
Total vitamin level (mg/kg)	100	100	100	100	100	100	100
Cost of feed ration per 100 hens per day	6.00	7.00	7.50	8.00	8.50	8.75	9.00
Number of eggs per 100 hens per day	70	70	75	80	85	80	80

Experiment 2

Protein concentration in feed (%)	14	14	14	14	14	14	14
Total vitamin level (mg/kg)	50	75	100	125	150	175	200
cost of feed ration per 100 hens per day	8.00	8.25	8.50	8.75	9.00	9.25	9.50
Number of eggs per 100 hens per day	70	80	85	90	95	95	95

Which feed composition gives the least cost per egg produced?

• A. Protein concentration (%) - 16; Total vitamin level (mg/kg) - 100
• B. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 50
• C. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 100
• D. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150

Answer 1

The correct option is D Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150

In Experiment 1-At protein concentration 16% vitamin level 100, the cost of feed is 9.00 and the number of egg produced is 80 per 100 hens

In experiment 2 - At protein concentration 14%, vitamin level 150, the cost of feed is 9.00 and the number of eggs produced is 95, an increase of 15 per 100 hens.

So, the correct answer is 'Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150'
