All animals and man can be hosts to parasites which live on the skin. These parasites look like insects.
⚫▪️𝗠𝗶𝘁𝗲𝘀: are very small and cannot be seen without a microscope. They live and lay their eggs on the skin.
⚫▪️𝗟𝗶𝗰𝗲: (singular is louse) are big enough for you to see. Man can be infected with the head louse. Cattle, buffalo, sheep and goats can be infected with different lice which attack the body, legs or tail region. Lice live and lay their eggs on the skin amongst the hair or wool.
⚫▪️𝗧𝗶𝗰𝗸𝘀 : are bigger than lice and can be as big as a fingernail. Young ticks have 6 legs while adults have 8 legs. All ticks feed on the blood of the host and then drop off onto the pasture. They lay their eggs on the ground. Some ticks live on one host while others may live on two or three different animals throughout their lives

▪️𝗠𝗶𝘁𝗲𝘀 cause mange. They infect the head, legs, body or tail region causing the skin to become crusted and cause loss of hair and wool. The infected area itches and the animal scratches. The host does not feed well. The infections cause loss of valuable wool in sheep and damage hides of cattle and goats.
Sometimes young animals become infected with a skin disease called ringworm. Ringworm causes circular, whitish patches on the skin which do not itch. Animals can have both mange and ringworm and large areas of skin may be affected
▪️𝗟𝗶𝗰𝗲: also cause irritation of the skin and the animal scratches, rubs and bites the infected areas. The host loses, or does not gain weight, and looks in poor condition.
Both lice and mites can pass from one animal to another. Biting and scratching are the first signs of infection. If you examine the animal you will be able to tell if the skin problem is caused by lice or mites, if lice are on the animal you will find them in its coat, if you do not see any the animal probably has mange caused by mites.
▪️𝗧𝗶𝗰𝗸𝘀 are very important parasites. They bite the host and suck its blood and when full drop off onto the pasture where they can live for many months without feeding again. Animals can be poisoned or paralysed by the bites of some ticks. Ticks also spread diseases, tick-borne diseases, which can cause death of the host. Ticks cause the loss of meat, wool, milk and leather.

▪️Mites and lice are controlled by washing the infected area, spraying or dipping the animal with a suitable treatment .All of the flock or herd must be treated to ensure control.
Some animals can be infected but show little or no sign of infection and the parasites will spread from them to other animals if they are not treated too.
▪️If an animal has only a few ticks these can be carefully pulled off making sure the mouthparts of the tick are removed. Rubbing ticks with a cloth soaked in kerosene (paraffin) will make them drop off the host. Large numbers of ticks are treated using sprays and dips . It will be necessary to treat all of the herd or flock.
▪️Moving animals to different pastures and resting the contaminated pasture for a length of time can help to control the ticks. Cutting the bushes and ploughing the affected area can help to control ticks. Large numbers of ticks can be found around water holes and animal shelters. Keeping poultry in these areas can help to reduce numbers of ticks as the birds will eat them.
▪️If mange or ticks are a problem in your community's livestock you should talk to your local veterinarian about it. He will advise you on the best treatment and control to use in your area. He may ask you to collect some ticks or take scrapings of skin from animals with mange so the parasite can be identified. This will help him to decide which treatment you should use.
