(a) ldentify specimens M, N, O, and P
(b) State three uses each of specimens M, N, and O.
(c) State one advantage each of using specimens M and N.
(d) State two disadvantages of using specimen P in brooding of chicks.
Explanation
a) ldentification of Specimens:
- M- chicks' water fountain/drinker/water
- N - wooden feed trough / feeding trough / feeder
- O - egg candler
- P- lantern/bush lamp/lamp
(b) Use of Specimens M, N, and O.
Chicks' water fountain;
- water is poured into the container and then covered with the base,
- the container is turned upside down so that water drips out of a small opening into the cover which serves as the base
- it is placed on the floor of deep-litter house or on a raised platform
- the chicks gather around the trough to drink water from the base.
Wooden feed trough;
- Feed is poured directly into the wooden trough and spread inside.
- Trough should be half-filled to avoid wastages resulting from scratching by chicks when feeding
- Trough is re-filled regularly as the content diminishes.
- It is usually placed On the floor of deep-litter house.
Egg Candler:
- The egg is placed in a hole on the candler, and the light is switched on to illuminate the egg thus, revealing the egg's content particularly the developing embryo.,
- the egg candler is usually used during or before incubation to determine the fertility of eggs.
(c) Advantages of using Specimens M and N:
Specimen M Chicks' water fountain;
- The water inside the trough cannot be easily contaminated by the chicks' droppings.,
- The system is cheap,
- is self-regulating, thus avoiding water wastage.
Specimen N Wooden feed trough:
- It is easy to construct
- cheap to construct,
- easy to maintain;
- reduces feed wastage:
- reduces feed contamination.
(d) Disadvantages of using Specimen P - lantern.;
- It is not very effective since few chicks can be taken care of,
- the fumes are unhealthy to chicks: and can cause fire disaster.,
- chicks can get burnt when they jump on top of the lantern
