A) About Cows:

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

1.   Bovine Virus Diarrhea (BVD)

This is one of the most costly diseases for cattle producers. Signs may include scours, nasal discharge, coughing and fever. BVD can also cause infertility, abortion and birth defects. Type 2 BVD can cause haemorrhaging and death in susceptible young calves and adult cows.

2.   PI3 (Parainfluenza Type 3)

This common, mild respiratory disease suppresses the animal's immune system, allowing other diseases to develop. The virus is shed in nasal and eye secretions, and infects non-vaccinated animals through the mouth and nasal passages.

3.   IBR (Infectious Bovine Rhinotracheitis)

Also known as "Rednose", this highly contagious virus causes respiratory disease, abortions and infertility. Signs include inflamed nasal passages, fever, rapid breathing, deep cough and loss of appetite.

4.   Mastitis

Bovine mastitis is the persistent, inflammatory reaction of the udder tissue due to physical trauma or microorganisms infections. Mastitis, a potentially fatal mammary gland infection.

5.   Internal Parasites

These diseases are caused by internal helminths (roundworms, tapeworms and flukes) as well as external arthropods (mites, lice, ticks, and flies).  Parasitic diseases of cattle impair health, reproduction, growth, and productivity.  In severe cases, parasitic diseases may even cause death.

B) About horses

1. Look for  a good website that refers to horses. Copy its link. Explain why you like the website. (50 words)

http://www.rodeoyrienda.cl/

I like this web site because; it represents very well the history of the Chilean horse. It is a very intelligent horse and pretty beautiful; also talks about anatomy, behaviour of them, etc.

I like too how this natural monument has been preserved because it has a
birth certificate control to register them.

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

3. Publish a good image of the horse's cardiovascular system (with names)
