Parasites hupunguza performance kimya kimya. Nguruwe anaweza kula kila siku lakini growth ikawa ndogo kwa sababu nutrients zinapotea au intestine imeathirika. Control nzuri inachanganya hygiene, manure management, stocking density, quarantine na treatment inayolengwa.

Internal parasites

Roundworms na worms wengine wanaweza kuishi kwenye intestine au tissues. Eggs zinaweza kuishi kwenye mazingira kwa muda. Outdoor pigs wako kwenye risk kubwa ikiwa pens/soil hazipumzishwi. Signs si specific: poor growth, pot belly, rough coat, diarrhoea, coughing na poor FCR.

External parasites

Mites na lice huleta itching, rubbing na skin damage. Nguruwe wanaweza kuambukizana kwa contact na contaminated housing/equipment. New breeding stock ni chanzo muhimu, hivyo quarantine na skin inspection ni muhimu.

Faecal examination

Faecal sample inaweza kusaidia kujua parasite burden na aina zinazohusika. Hii ni bora kuliko kutoa dewormer kila mwezi bila kujua kama inahitajika. Overuse inaweza kuongeza resistance na gharama.

Mpango wa control

• Safisha manure na wet areas.
• Tumia all-in/all-out inapowezekana.
• Tenganisha age groups.
• Quarantine na treat/assess newcomers kulingana na vet plan.
• Fanya faecal tests kwa risk periods.
• Tumia product sahihi, dose kulingana na uzito na withdrawal period.
• Pima response; ikiwa parasite problem inaendelea, chunguza resistance, reinfection na dosing accuracy.
