A) About Cows:

1. What are the  5 most common pathologies of cows? Mention them and give a little description too.

  • Foot and Mouth Disease: it is a highly contagious disease in livestock that causes lesions similar to blisters on the tongue, nose, mouth and toes of the animals. The disease does not normally kill the livestock but creates painful ulcers after the blisters burst, and can cause high fevers, weakened legs, and even the loss of the ability to walk. 
  • Brucellosis and tuberculosis: these are two highly contagious diseases carried by cattle. Similar in nature, these diseases are spread by infected material during calving. The diseases threaten humans, because the unpasteurized milk of infected cattle can spread the disease.
  • Anaemia: this in animals is often caused by bush ticks that attach themselves to the livestock. Normally found in the ears, around the tail, and on the underside of the animal, bush ticks transfer, especially to cattle, a disease known as theileriosis. The disease creates symptoms similar to anaemia in humans: lethargy, loss of appetite, inability to exercise. Cattle with anaemia may have pale/yellow colored gums and abort babies if pregnant.
  • Bracken poisoning: it most commonly occurs in the fall when grass does not grow. Bracken is a plant that contains toxins poisonous to animals who graze. Bracken is considered cancerous and is almost always fatal to infected livestock. When an animal eats a large amount of bracken, disease forms because of depressed bone marrow and lack of production of white blood cells. Death can occur as soon as five days after the first sign of symptoms.
  • Dehydration and heat stress: these are common issues livestock face during the hot summer months. This diseases can to cause Sunken eyes, yellow dark urine and fever. Treating dehydration requires rehydration of the animal with plenty of water and electrolytes.

1. Choose a good website that refers to your animal. Explain why you like the website. (50 words)

I choose the website livescience because it is a science magazine website. This online magazine is very important to global level. When I went to school my biology teacher sometimes say that "livescience" its a very good website to search information. So when I search information about rabbit and I found this page I think that get information will be sure. Then I get in to the page and I found many fact about rabbits like: size, offspring, diet, habitat, habits, taxonomy classification, species and conservation status. 


2. Find a good picture showing (with names) the animal's external anatomy.
