What are the sheep raised for? 101






What are the teeth for? 104 Teeth tells us what kind of food it eat. Canine teeth the long, pointed canine teeth stab into prey and hold it firmly. Carnassials teeth these scissor-like teeth slice flesh into chunks that the fox can swallow. Molars behind the carnassials teeth are used to crush bone. Plant-eater teeth (a sheep is a herbivore). Wide back teeth called premolars and molars up grass so it can be easily digested. Incisor teeth at the front of the jaw snip off mouthfuls of grass.

 

What are the teeth for? 80 For eating, chewing

 

What are the types of the teeth? 102 A tooth is a small, calcified, whitish structure found in the jaw of many vertebrates and use to break down food. Four types of teeth in an individual jaw: incisors (most anterior teeth), canines, premolars (lie immediately posterior to the canines), molars (most posterior teeth in the jaws).

What are the ways of brucellosis transmitting? 187 Brucellosis afflicts cattle, goats and swine. It can be transmitted from infected animals to man through raw milk, contract of an open sore or wound with an aborted fetus or after birth or from carcasses at the time of slaughter.

What are their symptoms? 181 There are some obvious signs of ill health, with sick sheep eating little, vocalizing excessively, and being generally listless.

What birds can the host birds spread the infection to? 118 Often unaffected themselves, the host birds can spread the infection to susceptible species, especially domesticated chickens, turkeys and geese, resulting in severe epidemics that kill large numbers of birds – sometimes in a single day.

 

What birds carry the viruses that cause bird flu? 117 Migratory waterfowl and ducks in particular carry the viruses that cause bird flu.

 

What can you tell about the circulatory system? 92 The circulatory system comprises the heart and the blood vessels – the arteries, the arterioles, the capillaries, the venulae and the veins. The heart pumps blood to various parts of the body.

What cattle does salmonellos is infect more often? 147 Salmonella live in the intestinal tracts of animals, including birds.

What destroys the virus? 122 Heat destroys the virus, but it can survive for extended periods in cool temperatures.

What disciplines does veterinary depend on? 5 Veterinary depends on several disciplines. Knowledge of Physics is essen- tial in understanding the function of the heart and blood vessels, the mechanics of respiration, the formation of images in the eye, and the transmission of sound waves in the ear. Knowledge of Chemistry is indispensable in unraveling secrets of digestion and metabolism and in understanding the way in which oxygen and carbon dioxide are carried in the blood. Physiology is the study of the phenomena presented by living organism. It is primarily a study of the function in the organs and the conditions, which determine their function in the living animal. To know the structure of the animal body veterinarians study Anatomy. Veterinarians must get deep knowledge of Biological chemistry because it is the basis of clinical laboratory diagnostics and therapy. Pharmacology is the scientific study of drugs and their use in the treatment of animal diseases and injuries. Hygiene is the practice of keeping animals and areas clean in order to prevent illness and disease.

What disease is anthrax? 171 Anthrax is an acute infectious disease caused by the bacterium Bacillus anthracis and is highly lethal in some forms.

What disease is cryptosporidium infection? 154 Cryptosporidium infection (cryptosporidiosis) is an illness caused by tiny cryptosporidium parasites. When cryptosporidia enter your body, they travel to your small intestine and then burrow into the walls of your intestines. Later, cryptosporidia are shed in your feces.

What disease is rabies? 162 Rabies is a very serious viral infection that targets the brain and nervous system. You can catch rabies if you are bitten by an infected animal and haven't been vaccinated.

What disease is salmonellosis? 146 Salmonellosis is a type of food poisoning caused by the Salmonella enterica bacterium. There are many different kinds of these bacteria. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common types in the United States.

Salmonellosis is more common in the summer than in the winter. Children are the most likely to get salmonellosis. Young children, older adults, and people who have impaired immune systems are the most likely to have severe infections.

What disease is the plague of dogs? 132 The plague of dogs is an infectious disease. It amazes dogs of young age, about one year.

What diseases of the sheep do you know? 180 Sheep may fall victim to poisons, infectious diseases, and physical injuries.

What do circulatory organs consist of? 34 The circulatory organs consist of the heart, the arteries, the arterioles, the capillaries, the venulae, and the veins. Together they comprise the so-called vascular system. This system is a set of closed tubes beginning and ending at the heart and having only one or two openings.

What do scientists think about outbreaks of bird flu? 124 Scientists don't think that migratory birds are carrying the virus from continent to continent because outbreaks haven't followed traditional flyways.

What do we call the bones of the head? 66 The skull of mammals consists of 30 separate bones that grow together during development to form a solid case protecting the brain and sense organs. The “box “enclosing and protecting the brain is called the cranium (see diagram 6.4). The bony wall of the cranium encloses the middle and inner ears, protects the organs of smell in the nasal cavity and the eyes in sockets known as orbits. The teeth are inserted into the upper and lower jaws (see Chapter 5 for more on teeth) The lower jaw is known as the mandible. It forms a joint with the skull moved by strong muscles that allow an animal to chew. At the front of the skull is the nasal cavity, separated from the mouth by a plate of bone called the palate. Behind the nasal cavity and connecting with it are the sinuses. These are air spaces in the bones of the skull which help keep the skull as light as possible. At the base of the cranium is the foramen magnum, translated as “big hole”, through which the spinal cord passes. On either side of this are two small, smooth rounded knobs or condyles that articulate (move against) the first or Atlas vertebra.

What does anatomy deal with? 10 Anatomy is the branch which deals with the form and structure of the principal domestic animals. Anatomy, histology, cytology and embryology.

What does anatomy use to understand the structure of the organism? 11 Anatomy, histology, cytology and embryology constitute the general science of the form, structure and development of the organism which is called morphology.
