Here are some common clinical signs of a horse with a heavy parasite burden. This could be due to a lack of worm count testing and poor management, or it may result from over-worming, which has led to worm resistance. 🪱💩🌱🐴
1. **Weight Loss**: Despite having a good appetite, a horse may lose weight due to parasites consuming nutrients.
2. **Poor Coat Condition**: A dull, rough, or unkempt coat can indicate underlying health issues, including parasites.
3. **Colic**: Recurrent episodes of colic can be a sign of parasitic infection, particularly if the parasites cause blockages or irritation in the intestines.
4. **Diarrhoea**: Frequent loose stools or diarrhoea can result from parasitic infections affecting the digestive system.
5. **Lethargy**: A noticeable decrease in energy or activity levels may indicate that the horse is battling a heavy parasite load.
6. **Bloating or Distended Abdomen**: A swollen belly can occur if parasites are causing gastrointestinal issues.
7. **Anaemia**: Pale gums and a lack of energy can indicate anaemia, which may result from blood-feeding parasites like strongyles.
If you notice any of these signs, it's important to consult a veterinarian for a proper diagnosis and treatment plan.
Both over-worming and a lack of worm count testing can lead to the same end result. Although over-worming can arguably be worse, as it contributes to the development of resistance, meaning further treatments may be ineffective and the clinical signs may persist and worsen.
