EXTERNAL PARASITES: TICKS

Ticks! Ticks! Ticks!

Ticks are blood sucking insects found on livestock, primarily cattle, goats and sheep.  Ticks are also found in game animals.

If left unchecked and controlled, this external parasite can significantly reduce cattle weight and milk production.  Mmmm! Could that be why some cattle are skinny?

1.  The mature female lays up to 3000 eggs and dies.

2.  The eggs/larvae hatch.  Once hatched they climb on the grass.       They also hide in tree barks. 

3.  As the animals graze, the ticks climb on their bodies and attach     mouth pieces on the animals skin.
4.  Here, on the animals body, they grow and develop further             becoming more mature with every drop of blood.
5.  The female ticks detach from animals body into the environment.     And lay eggs again.  Process than repeats itself many times         more.

Below are the effects of ticks on livestock.

Loss of blood
It is believed that every tick sucks 30 drops of blood in its life time.  Image an animal with hundreds of ticks.  The loss of blood results in retarded growth and weight loss.

Toxins
The saliva found in ticks release toxins in the body of an animal. This than effects health and productivity of animals.

Diseases
Ticks are great disease carriers.  Tick borne diseases are theileriosis, heartwater, redwater, gallsickness and sweating sickness (in calves).

Wounds
These wounds can be super massive.  When attaching mouthpieces demage the skin tissue, leaving wounds.  As a results, germs can pass though into the animals body. Worms can easily enter and gather around the wound and cause more harm.

Tick worry
How irritating!  I would be irritating if I had ticks on my body and do not know how to remove them.   This results to limited grazing.

Loss of distal end of tail
I have seen this!  Numerous times!  Clusters of ticks on tail brush cause harm.

Pain
The bite is painful.


How do I control this disaster?

Ticks can be controlled easily.  There are a lot of effective drips, sprays and ointments that can be applied to an animal.  You can contact your nearest VET and ask for advice.  I personally use deadline on ticks.  Its quiet expensive, but useful.  Building dipping trenches can also be used to kill ticks.  As for sweating calves, we have been using traditional alcohol like 'tomboo'.  It seemed to have worked.
