&PARASITES
Submission
Form
From 'House Cows' providing the family's milk to rare breed stud bulls, cattle form a key role on the smallholding. But there is a world of parasites in your grazing keen to infect your precious cows.
​
Good parasite control can increase the quality of cows you sell, improve their growth & feed conversion rate and substantially increase their milk yield. Over-do your wormer use and you'll just breed resistance.
​
Recommended cow FEC testing frequency: every 3-4 months
Optimum Schedule: Jan-Feb, May, Aug-September
Plus: mum & calf at 3-6 weeks old for coccidia
​
Cost of WEC test: £14.50 up to 5 samples
