Checked by the Skolra question team · Last updated 23 October 2026

WAEC Animal Husbandry: 244 objective past questions from 8 papers between 2016 and 2023, each with the answer and an explanation. Here are ten.

1. 1.Which of the following feed ingredients is required most in formulating ration of layers?
   1. A
      Bone meal
   2. B
      Maize
      Correct
   3. C
      Fish meal
   4. D
      Vitamin-mineral premix
   Show answerHide answer

   Answer: B

   Maize is correct. When a ration is formulated, ingredients are combined in different proportions depending on the nutrient they supply and how much of that nutrient the bird needs in bulk.

   So although calcium is critical for layers specifically, the question is about which ingredient is needed in the greatest quantity in the ration - and that is the energy source, maize.

2. 2.The transfer of an animal from its country of origin to another country is called
   1. A
      Transhumance
   2. B
      Importation
   3. C
      Exportation
      Correct
   4. D
      Migration
   Show answerHide answer

   Answer: C

   Exportation is the correct term. It is defined as the transfer (sending out) of an animal from its own country of origin to another country, usually for sale or to help improve livestock stock in the receiving country.

3. 3.In West Africa, farm animals are mostly kept for___________
   1. A
      Meat production
      Correct
   2. B
      Draught (farm labour) purposes
   3. C
      Milk production
   4. D
      Egg production
   Show answerHide answer

   Answer: A

   Meat production is correct. In West Africa, including Nigeria, farm animals such as cattle, goats, sheep, pigs and poultry are kept mainly to supply meat as a source of animal protein in the diet.

4. 4.which of the following types of meat is obtained from sheep?
   1. A
      Mutton
      Correct
   2. B
      Pork
   3. C
      Chevon
   4. D
      Beef
   Show answerHide answer

   Answer: A

   In animal husbandry, each livestock species has a specific name for the meat it provides. Mutton is the meat gotten from sheep, which is why it is the correct answer here.

5. 5.Cellulose is broken down in the rumen mainly with the help of _____
   1. A
      Micro-organisms (bacteria and protozoa) living in the rumen
      Correct
   2. B
      Salivary amylase produced in the mouth
   3. C
      Pepsin enzyme secreted by the stomach wall
   4. D
      Hydrochloric acid secreted by the abomasum
   Show answerHide answer

   Answer: A

   Ruminant animals such as cattle, sheep and goats do not themselves produce cellulase, the enzyme needed to break down cellulose, the tough fibrous carbohydrate in plant cell walls. Instead, the rumen (the first and largest chamber of the ruminant stomach) houses a huge population of micro-organisms — bacteria and protozoa — living in a symbiotic relationship with the animal. These micro-organisms produce cellulase and other enzymes that ferment cellulose into volatile fatty acids, which the animal absorbs and uses as its main source of energy.

6. 6.Anaemia in farm animals is caused by
   1. A
      Deficiency of calcium and phosphorus in the diet
   2. B
      Deficiency of vitamin A in the diet
   3. C
      Blood-sucking parasites such as ticks, lice and mites
      Correct
   4. D
      Excess carbohydrate in the ration
   Show answerHide answer

   Answer: C

   Anaemia is a condition in which an animal's blood has too few red blood cells or too little haemoglobin, so the blood cannot carry enough oxygen round the body. The animal becomes weak, pale (check the gums and inner eyelids) and tires easily.

   So the correct cause of anaemia here is the blood-sucking parasites, because they remove blood directly from the animal's body.

7. 7.Which of the following disease would directly affect milk production in cows
   1. A
      Foot-and-mouth disease
   2. B
      Trypanosomiasis
   3. C
      Mastitis
      Correct
   4. D
      Brucellosis
   Show answerHide answer

   Answer: C

   Mastitis is correct. Mastitis is an inflammation of the udder (mammary gland), usually caused by bacteria entering through the teat canal. Because it attacks the milk-producing tissue of the udder directly, it reduces milk yield, changes the milk's colour and consistency (clots, blood-tinged or watery milk), and can make the milk unfit for sale or consumption. This is why mastitis is the disease most directly linked to milk production in dairy cows.

8. 8.pasture crops are best used in preparing silage when they
   1. A
      have wilted and dried out in the field
   2. B
      are young and succulent
      Correct
   3. C
      have matured and become fibrous and woody
   4. D
      have flowered and are beginning to set seed
   Show answerHide answer

   Answer: B

   Pasture crops are best used in preparing silage when they are young and succulent, usually cut just before flowering.

9. 9.Which of the following signs is not exhibited by an animal on heat?
   1. A
      Reddening and swelling of the vulva
   2. B
      Mounting of other animals in the herd
   3. C
      Restlessness and frequent bellowing
   4. D
      A marked increase in milk yield
      Correct
   Show answerHide answer

   Answer: D

   An animal on heat (oestrus) shows a well-known set of physical and behavioural changes caused by the surge in oestrogen just before ovulation.

10. 10.Which of the following plants is not a forage legume?
    1. A
       Stylosanthes guianensis
    2. B
       Centrosema pubescens
    3. C
       Panicum maximum
       Correct
    4. D
       Calopogonium mucunoides
    Show answerHide answer

    Answer: C

    Panicum maximum (Guinea grass) is the odd one out. It belongs to the grass family (Poaceae), not the legume family (Fabaceae/Leguminosae), so it is not a forage legume — it is a forage grass.

    The other three are all well-known tropical forage legumes used for pasture improvement and as cover crops in Nigeria:

    Centrosema pubescens (centro), Stylosanthes guianensis (stylo), and Calopogonium mucunoides (calopo) are all creeping or climbing legumes that form root nodules with Rhizobium bacteria, fixing atmospheric nitrogen and enriching the soil while also providing protein-rich fodder for livestock.
