Observation

1. It is surprising to note that some candidates concluded that the knapsack sprayer is used for killing insects, weeds etc instead of its use in animal production.
2. Only few candidates  understood the major nutrients in palm kernel cake as some of them wrote iron, calcium, potassium etc; thus losing marks.
3. Many candidates are unfamiliar with the advantages of feeding rabbits with plantain peels. The candidates noted that ‘it is cheap’, easily available’ etc but the major test is the advantages of plantain peels as a fibre source in rabbit nutrition.
