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
3. Publish a good image e of the cow's skeletal system (with names)

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.
