In a Nutshell Apple cider vinegar has been long advocated for its health benefits. Apple cider vinegar is held to have multiple medicinal purposes, ranging from improved haircoat, to greater milk production and reduced mastitis, to decreased urinary calculi in bucks, to increased doe kids of supplemented dams. Three Iowa farms tested treatments of apple cider vinegar suppliments in goat production. Animals were weighed at the begin- ning and end of the trial, and total and average daily gains were calculated. No great gains were seen, but benefits were observed. Time Period: May-September 2013 Background Apple cider vinegar (ACV), an acidic fermentation product, has been long ad- vocated for its health benefits. It contains mainly acetic acid, as well as vitamins, mineral salts, some amino acids, polyphe- nols, and other organic compounds (John- ston and Gaas 2006). While not extensive or replicated in many larger mammals, trials on rodents have found lowered blood pressure after ACV supplementa- tion, perhaps due to changes in calcium absorption, possibly due to pH changes (Kondo et al. 2001). Among farmers, ACV is held to have multiple medicinal purposes, ranging from improved haircoat, to greater milk produc- tion and reduced mastitis, to decreased urinary calculi in bucks, to increased doe kids of supplemented dams (Welcome Home Farm 2011, Winter 2012). Some credit is given to the vitamins, minerals, and other nutrients in ACV, though the concentrations are extremely low (Mercola 2009). Meanwhile, farmers report goats enjoying water with some ACV added – perhaps the improved hydration is part of the health benefits (TheGoatSpot 2009). Acetic acid, the main acid of vinegar, is used by the mammary gland for fat synthesis (Marinez et al. 1976), but it is uncertain whether an animal will willingly consume enough ACV to cause a notice- able increase. In addition, the acid and other compounds are said to correct pH imbalances in the body; again the volume of ACV required to elicit a change is questionable (Acres USA). In hamsters, a connection has been found between off - spring sex and vaginal pH at mating; lower pH towards the end of estrus is correlated with more male births (Pratt et al 1987). While similar observations are made for cattle – more females if bred early – it is not known whether there is a pH differ - ence; and ACV supplementation should theoretically decrease pH (associated with males, at least in hamsters). Practi- cal Farmers, curious about these claims, designed a project to track differences in ACV-supplemented and unsupplemented goats over several months. Come next spring, the sex of the does’ kids will be reported as well.
