However, in 8(c) (i-iii), majority of the candidates could not solve the calculation on the formulated diet as presented in the table above.
The expected answers include:
Weight gain per day
- Weight gain = Final - Initial
- Diet I = 70 – 40 = 30kg
- Diet II = 79 – 41 = 38kg
- Diet III = 88 – 38 = 50kg
- Diet IV = 76 – 42 = 34kg
- Weight gain per day
1000g = 1 kg = Weight gain x 1000g
(180 days)
Diet I = 30 kg x 1000
180 = 166.67g
Diet II = 38 kg x 1000
180 = 211.11g
Diet III = 50 kg x 1000
180 = 277.78g
Diet IV = 34 kg x 1000
180 = 188.89g
Feed intake per day = Total feed intake
180 days
Diet I = 576 kg = 3.2 kg
180
Diet II = 738 kg = 4.1 kg
180
Diet III = 450 kg
180 = 2.5 kg
Diet IV = 558 kg
180 = 3.1 kg
Percentage of the body weight
= Feed intake per day x 100
Final live weight
Diet I = 3.20 x 100
70 = 2.24%
Diet II = 4.1 x 100
79 = 3.24%
Diet III = 2.5 x 100
88 = 2.20%
Diet IV = 3.1 x 100
76 = 2.36%
