Sulfadimethoxine For Goats

Coccidiosis is caused by microscopic protozoan parasites called coccidian (Eimeria spp.). Coccidia go through a complex “life cycle” in the intestinal cells of goats. In the process, they produce large numbers of eggs (technically called oocysts) that are passed in the feces. In the process of growth and multiplication in the goat intestinal epithelial cells, the coccidia may destroy many intestinal cells. This may cause diarrhea and other signs of the disease coccidiosis. Coccidiosis is the most common cause of diarrhea in goats between 3 weeks and 5 months of age. This is especially true when goats are housed in confinement. Coccidiosis commonly strikes young goats shortly after weaning because of the stress of being suddenly separated from their dam.

Coccidiosis is a disease that results from overcrowding, dirty and/or wet pens, and unclean water. Coccidiosis is highly contagious and spreads through a herd rapidly. The first symptom is usually but not always diarrhea. Along with diarrhea always comes dehydration and sometimes fever. If treatment isn’t begun immediately, permanent damage will be done to the intestinal lining and the goat won’t be able to absorb nutrients from its food. Weight loss is substantial and too often chronic (cannot be cured); if it lives, the goat will always be unthrifty. In advanced cases of Coccidiosis, diarrhea can be watery, and may contain mucous and blood. Bloody diarrhea is blackish in color.


This antibiotic is effective against Streptococcus spp., Staphylococcus spp., KlebsiellaProteus, some E. coli and Salmonella organisms. It is also effective against coccidia organisms. Indications for Use: Use for pneumonia (shipping fever), footrot, and coccidia cases. Not approved for use in sheep and goats. Refer to extra-label drug use.

Dosage and Administration:

 Give 25 mg per pound of body weight (55 mg/kg) on the first day and then 12.5 mg per pound for 3-4 more days. This means giving 1/2 of a 5 g bolus per 100 lbs. on the first day and then 1/4 of a 5 g bolus per 100 lbs. for the following 3-4 days. For coccidia, some veterinarians recommend giving 35 mg per pound (75 mg/kg) of body weight for 3-5 days.

Duration of Treatment: If signs continue for longer than 3-4 days, re-evaluation of the problem, along with culture and sensitivity, should be considered.

Precautions and Side Effects: Side effects are of minimal concern.

Dosages for Treatment: DiMethox 

Many goat producers have the DiMethox 12.5% on hand to treat coccidia. My veterinarian recommends this one and has it on hand for me to purchase. So, it’s the one I use.
DiMethox 12.5% solution is my #1 pick for treating coccidiosis effectively.  Many producers use this as well. While it comes in liquid and powder form, I prefer liquid drenching to make sure each affected animal is receiving the recommended dosage. The dosage for succesful coccidiosis treatment using the DiMethox 12.5% is 1.6 cc per 5 pounds for 5-7 days in a row. 

Also, Di-Methox 12.5% could also be added to drinking water; follow package directions. However, I’m not a fan of adding to drinking water because I’m not sure how much medication the animal is receiving to successfully treat coccidiosis. I would rather exactly how much by drenching. Consequently, Dimethox 40% is considerably stronger than the usual 12.5% drinking water solution.  So, you can use 1/3 as much of the 40%. The dosage is 1 cc per 15 pounds for at least 5 days and no more than 7 days.
