PRINCIPAL GOAT DISEASES |
|
Goats are animals subject
to many diseases. These are divided into three groups: -caused
by parasites or protozoa (intestinal verminous,
Coccidiosis....); -caused
by bacteria (Brucellosis); -caused
by viruses (C.A.E.V.). The
Brucellosis is the most dangeurous diseases for man; infact it is trasmitted
eating not cooked milk and cheese. Another way for the infection is the
contact with a death foetus, when there is an abortion of the animal. The
symptoms of this illness are natural abortions in this case also cattle can
be infected if it's breed in the same shed. In the man the disease called
Malta fever or undulatory fever. It prodeces a sudden thermical rise,
followed by periods of apparent normality; for this it is difficult to
dyagnose. Today it's curable, but in many cases it leaves conseguences people
such as: trembling or nodules. In the
territory the control by the Vet Service for the Brucellosis, is made through
blood samples from animals that have an age over 6 months. Other
sanitary controls of the Vet Service are made on food through the analysis of
fedders. Also the sanitary condiction of animal shelters are controlled. At
the end there's a control through milk testing that must be free of bacterial.
In the cheese production farms the rooms used for processing cheese are
controlled. C.A.E.V.
(the French name for Caprine Encephalitis Arthritis) is a disease that
arrived in our territory in the last years. The
diffusion of C.A.E.V. in this area dates back to the '70's, when after a
renewed interest in goat breeding, many animals were imported from other
neighbouring European contries, in particular from France. Probabily some
imported goats were infected by this illness. The
Caprine Encephalitis Arthritis is a diseases caused by a virus that produces
in infected goats a diminution in the quantity of milk produced and a bone
decalcification. It's a
virus that can be latent in the animal, in this phase there aren't visible
sign of the illness; it can also be clearly. In many case the latent phase
passes to diagnosed, but it can also remain in the first phase. Among
the goats the infection is pricipally trasmitted through suckling , because
the mother's milk produced just after birth made up many antibodies.
Infection caused by living togheter in the same shed with ill animal is also
possible. In the
mid '90's in our area fist experimental programs for defeating the disease
was started. Before this project was carried out only in Switzerland and
France. Later after some controls it was discovered that in the vet district
of Asti all animals were sick, although they didn't show any
symtom. The
program foresees a separation between the babies and the mother, just after
birth in order to avoid contagion; then these babies grow and live for all
their life in a separating shed. In many case there was another way for the
infection caused by the breeder looking after them then it was planned
to create weaning centres: the kid was separated from the mother and given to
another breeder that bred it with artificial milk and then grew it with other
healthy animals. As for
intestinal verminous each breeder cares for his animals once a year. Despite
the diffent diseases that can infect a goat, the most frequent case of death
is due to birth infection or difficulties. Infact the goat has got a very
thin uterus and if a breeder tries to help the animal at the moment of birth
he may cause very serious damages. |
