Animal Husbandry WAEC

Anatomy And Physiology And External Orientation

Übersicht

Before a livestock officer opens a single textbook on the rumen or the heart, she runs her eyes and her hands over the animal in front of her: the set of its ears, the fill of its flank, the dryness of its muzzle, the way it stands on its pasterns. Every farmer, buyer and veterinary officer in Nigeria reads an animal this way first, from the outside in, using a shared vocabulary of named body regions long before any internal system is discussed. That vocabulary, and the two words that frame everything else in this section of the syllabus, anatomy and physiology, are what this lesson builds.

You will learn precisely what anatomy and physiology mean and how they differ, why a stockman who knows both spots trouble earlier and treats it more safely, and the standard external points, poll, muzzle, dewlap, withers, brisket, barrel, flank, hock and pastern, used to describe conformation and locate a problem exactly. Eight further notes in this section will each open up one internal system, the digestive, nervous, endocrine, integumentary, skeletal, muscular, reproductive, circulatory, respiratory and excretory systems in turn, and every one of them leans on the orientation you learn here.

Lektionshinweis

A goat keeper in Gwagwalada calls the nearest veterinary extension officer to report that his West African Dwarf goat is unwell. If he can only say "it looks sick", the officer learns almost nothing. If instead he says the goat's flank looks tucked up and hollow, its muzzle is dry, and there is a soft swelling near the brisket, the officer can already begin narrowing down the problem before ever seeing the animal. The difference between those two phone calls is anatomy, the shared vocabulary of named body parts, working alongside physiology, the understanding of what a normal, healthy body is supposed to be doing at each of those parts. Every topic in this section of the syllabus, from the digestive system to the skeleton to reproduction, is built on the orientation this lesson teaches.

Specimen K (Head of a cock)

(a) Drawing and labelling of five parts of specimen K

The head of a cock is drawn below with five parts clearly labelled: the comb, the eye, the beak, the nostril and the wattle.

figure
Labelled drawing of Specimen K - the head of a cock.

(b) One function of each of the labelled parts

Labelled partOne function
CombHelps to regulate the body temperature of the bird (heat loss).
EyeFor sight / vision.
BeakFor picking up feed and drinking water (also for scratching and defence).
NostrilFor breathing (respiration) and for smelling.
WattleAids temperature regulation and serves as a sign of sex appeal / maturity.

(c) Two management practices that could be carried out on specimen K

  1. Debeaking - trimming the tip of the beak to prevent cannibalism, feather pecking and egg eating.
  2. Dubbing (decombing) or dewattling - trimming the comb and/or wattle to prevent frostbite and injury and to reduce fighting.

Specimen L (Pair of scissors)

(d) One tool that could be used in place of specimen L

A sharp knife could be used in place of the pair of scissors to carry out the management practices on specimen K. (A sharp blade, a scalpel or a beak trimmer would serve the same purpose.)
