FARM ANIMAL DISEASES.

 

Names of disease causing organisms

Be reminded that a disease is an abnormality in health. They are caused majorly by micro-organisms known as pathogens such as Virus, Bacteria, Fungi, Protozoan and Worms.

These disease organisms get into the animals by various means.

1. Droppings of infected animals,

2. Contaminated feeds and water,

3. Contact with infected animals,

4. Air,

5.insects,

6.feed or water troughs.

Diseases of livestock could be infectious or contagious.

Infectious disease affects animals without physical contact with the infected animals. It can be transmitted to healthy animals through water, air, or feed. E.g Anthrax, Coccidiosis, and Fowl typhoid.

While Contagious disease affect animals when there is physical contact with the infected animals.e.g Contagious abortion(bucellosis) ,Foot and Mouth , and Mastitis(inflammation of the udder)

Diseases that are transmitted from animals to human are termed Zoonotic disease. e.g Bird flu and Swine fever. It could cause death if not treated properly.

 

Names of diseases, causative organisms livestock affected, symptoms, mode of spread and control measures 

• Names of diseases = mastitis
• causative organisms = bacteria
• livestock affected = cattle
• symptoms = the udder becomes swollen, reddened and painful
• mode of spread = water, food, injuries on the udder, milking machine
• control measures = good hygiene, get rid of files, disinfect milking machine

 

• Names of diseases = contagious abortion
• causative organisms = bacteria
• livestock affected = cattle
• symptoms = irritation, catarrhal condition in the womb
• mode of spread = serving the infected bull, files, contaminated pasture
• control measures = vaccination, contact a vet doctor

 

 

• Names of diseases = Anthrax
• causative organisms = bacteria
• livestock affected = cattle, sheep and goat
• symptoms = blood stained discharge from mouth or nostril, swelling of the neck, death of the livestock
• mode of spread = contact with the infected animals or their produce
• control measures = invite the vet doctor, disinfect pens, burn or bury dead animals

 

 

 

• Names of diseases = tuberculosis
• causative organisms = bacteria
• livestock affected = cattle, sheep, goats, poultry, pigs
• symptoms = persistent cough, emaciation, loss of weight, death
• mode of spread = contact with the discharge or sputum of the infected animals
• control measures = vaccination, if the animal dies, bury the infected animal

 

 

 

 

• Names of diseases = fowl typhoid
• causative organisms = bacteria
• livestock affected = poultry
• symptoms = dullness, yellowish discharge
• mode of spread = contacted with the infected bird
• control measures = vaccination, proper sanitation

 

 

 

• Names of diseases = foot and mouth diseases
• causative organisms = virus
• livestock affected = cattle
• symptoms = sores on the feet, lips, foaming, lameness
• mode of spread = contact with the infected animals
• control measures = vaccination and isolation

 

 

 

• Names of diseases = Rinderpest
• causative organisms = virus
• livestock affected = cattle
• symptoms = blood stained diarrhea, grind of teeth, difficult in breathing
• mode of spread = contact with the infected animal or food
• control measures = vaccination

 

 

 

• Names of diseases = ringworm
• causative organisms = fungus
• livestock affected = all animals and birds
• symptoms = lesions or scab on the skin. Falling off of grey patches on wattle and combs of birds
• mode of spread =contact with the infected birds
• control measures = treat with iodine, good sanitation, isolate the infected bird

 

 

• Names of diseases = Trypanosomiasis
• causative organisms = protozoa
• livestock affected = cattle
• symptoms = weakness, sleepy
• mode of spread = through tsetse flies bites
• control measures = treat with trypanosomide drug, clear bushes around pen, kill flies with chemical

 

 

 

• Names of diseases = coccidiosis
• causative organisms = protozoa
• livestock affected = poultry
• symptoms = blood stained watery droppings, ruffled feather, loss of weight, death
• mode of spread = contact with contaminated feeds or water
• control measures = good sanitation, treat with the right medicine

 

 

 

 

 

 

 

 

 

 

Presentation

 

The topic is presented step by step

 

Step 1:

The class teacher revises the previous topics

 

Step 2.

He introduces the new topic

 

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

Conclusion

The class teacher wraps up or concludes the lesson by giving out short notes to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where the needs arise.
