Guidelines for Collecting Samples
Number of goats to be sampled:
• If the herd consists of fewer than 10 goats, sample all goats.
• For herds up to 50 in number, sample 10 to 15 goats.
• For herds up to 100 , sample 20 to 25 goats.
• Use the same animals for sampling throughout the year.
• We will be taking samples every 8 weeks for a total of 6 times.
Animals requiring worming will be retested two weeks after they have been wormed to measure effectiveness of the wormer being used.
Fecal samples must be fresh. Pellets can be stored in a refrigerator for 1 to 2 days but should not be frozen. However, it is best to test samples the same day.
Samples can be collected in two ways. A producer can watch his/her goats and collect fresh pellets after defecation or the producer can put on an examination glove, lubricate with water and tease five to six pellets from the rectum. In either case, the pellets should be put into a ziplock bag and the animal’s identification number and/or name be recorded on the bag. After fecal samples are collected, the producer needs to assess the goats FAMACHA score and write the score on the ziplock bag.
The cost of fecal samples will be 50 cents per sample if the producer assists in making slides. If the producer is unable or unwilling to assist in slide production the cost will be $2.50 per sample.
