WAEC Animal Husbandry 2022 questions and answers

1. 1.Farm animals with four-chambered stomach are referred to as
   1. A
      Ruminants
      Correct
   2. B
      Pseudo-ruminants
   3. C
      Monogastrics
   4. D
      Omnivores
   Show answerHide answer

   Answer: A

   Ruminants is correct. Ruminants are farm animals with a four-chambered stomach — the rumen, reticulum, omasum and abomasum — which allows them to digest fibrous plant material (cellulose) through microbial fermentation before true digestion happens in the abomasum (the "true stomach"). Examples include cattle, sheep, goats and buffalo.

2. 2.The number of animals that could be grazed on a given pasture land is referred to as
   1. A
      Stocking density
   2. B
      Grazing intensity
   3. C
      Carrying capacity
      Correct
   4. D
      Stocking rate
   Show answerHide answer

   Answer: C

   Carrying capacity is the correct term. In animal husbandry, carrying capacity is defined as the number of animals that a given pasture (or rangeland) is able to support (graze) over a given period, usually a grazing season, without causing damage to the pasture or a decline in animal performance.

3. 3.A secondary reason for keeping dairy cow is for
   1. A
      Work purpose
   2. B
      Milk production
   3. C
      Mutton production
   4. D
      Breeding purpose
      Correct
   Show answerHide answer

   Answer: D

   Breeding purpose is correct. A dairy cow is kept first and foremost to produce milk — that is its primary reason. But a dairy herd must also be bred continuously: cows are mated to produce calves that replace ageing animals, build up herd size, and allow the farmer to select and improve the stock over time. That makes breeding a genuine secondary reason for keeping the animal.

4. 4.Which of the following diseases is transmitted by tick?
   1. A
      Trypanosomiasis
   2. B
      Newcastle disease
   3. C
      East Coast fever
      Correct
   4. D
      Foot-and-mouth disease
   Show answerHide answer

   Answer: C

   East Coast fever is the disease transmitted by tick. It is caused by the protozoan parasite Theileria parva, which the brown ear tick (Rhipicephalus appendiculatus) picks up from an infected animal and injects into a healthy one while feeding. This is why farmers are taught to dip or spray cattle regularly to control ticks and reduce the spread of this disease.

   So whenever a question links a disease directly to the tick as the carrier, East Coast fever is the one to pick among these.

5. 5.The type of animal identification commonly used by herds in West Africa is
   1. A
      Ear notching
   2. B
      Branding
      Correct
   3. C
      Ear tagging
   4. D
      Tattooing
   Show answerHide answer

   Answer: B

   Branding is the method of animal identification commonly used by herds (especially cattle herds kept by pastoralists such as the Fulani) in West Africa.

6. 6.Microbial digestion and enzymatic digestion occur in the
   1. A
      poultry and rabbits
   2. B
      non-ruminant livestock
   3. C
      pigs and poultry
   4. D
      ruminants such as cattle, sheep and goats
      Correct
   Show answerHide answer

   Answer: D

   Farm animals are grouped by how they digest their feed. Ruminants such as cattle, sheep and goats have a compound (four-chambered) stomach, and their digestion happens in two stages: first, bacteria and protozoa in the rumen and reticulum break down fibrous plant material such as cellulose — this is microbial digestion. The partly fermented feed then moves to the abomasum (the "true stomach"), where gastric juice and enzymes complete the breakdown — this is enzymatic digestion. Because both processes happen in these animals, "ruminants" is the correct completion.

7. 7.During Artificial Insemination, semen is diluted with glycerol to
   1. A
      kill disease-causing microorganisms present in the semen
   2. B
      supply nutrients to nourish the sperm cells
   3. C
      increase the volume of the semen for more insemination doses
   4. D
      protect the sperm cells from damage caused by cold shock during freezing
      Correct
   Show answerHide answer

   Answer: D

   In Artificial Insemination (A.I.), collected semen is mixed with a diluent (extender) that is made up of several components, each doing a specific job. Glycerol is added specifically because it is a cryoprotectant: it gets inside the sperm cell and around its membrane and stops sharp ice crystals from forming when the semen is cooled and frozen (usually in liquid nitrogen) for storage. Without glycerol, the ice crystals that form during freezing would tear the sperm membrane and kill the cells. So glycerol's job is to protect the sperm cells from this cold/freezing damage, which is often called "cold shock protection".

   Because glycerol's defining and well-known function in A.I. is protecting sperm from freezing/cold-shock damage, that is the correct answer.

8. 8.Vaccination provides immunity against a disease because it stimulates the body to produce
   1. A
      Antibodies
      Correct
   2. B
      Hormones
   3. C
      Antigens
   4. D
      Toxins
   Show answerHide answer

   Answer: A

   Antibodies is correct. When an animal is vaccinated, a weakened or inactive form of a disease-causing organism (the antigen) is introduced into the body. This stimulates the animal's immune system to recognise the antigen as foreign and respond by producing antibodies that are specific to it. These antibodies remain in the blood (or can be quickly reproduced from memory cells) so that if the animal later meets the real, active disease organism, it is destroyed before it can cause illness. This is the whole basis of vaccination giving immunity.

9. 9.The causative organism of contagious abortion in cattle is called
   1. A
      Brucella abortus
      Correct
   2. B
      Trypanosoma brucei
   3. C
      Mycobacterium bovis
   4. D
      Clostridium chauvoei
   Show answerHide answer

   Answer: A

   Brucella abortus is the bacterium that causes contagious abortion (brucellosis) in cattle. It infects the placenta and uterus of pregnant cows, leading to abortion in the later stages of pregnancy, retained placenta, and reduced fertility. The disease spreads easily among a herd through contact with aborted material, afterbirth, and infected milk — which is why it is called "contagious" abortion.

   So the correct organism that specifically causes contagious abortion in cattle is Brucella abortus.

10. 10.Which of the following livestock parasites possesses a rostellum?
    1. A
       Liver fluke
    2. B
       Tick
    3. C
       Tapeworm
       Correct
    4. D
       Roundworm
    Show answerHide answer

    Answer: C

    The tapeworm is correct. A tapeworm's head region, called the scolex, carries suckers for gripping the host's gut wall, and in many species the scolex also bears a small, often retractable, hook-bearing projection called the rostellum. The rostellum, together with the suckers, anchors the tapeworm firmly to the intestinal lining of the livestock host so it is not swept away with the gut contents.
