Foaling S Revisited ome years ago while researching articles, a friend and I stumbled upon a one-of-a-kind foaling cam website. Thus began an addiction to MareStare, one that has plagued me for many seasons. And evidently I am not alone. It allows any viewer the opportunity to share in the beautiful foaling process and the agony of waiting hours for “something” to happen. My quick search of foal cams reveals open access to a small farm in central North Carolina, Brookhaven Miniatures. Owner Merry Black has been raising AMHA horses since 1998 and foaled out a handful of regular size horses before that- around 80 foals total. So you might say she has a good bit of experience! Merry has refined her foaling technique, but she is the first to tell you mini foaling is not for the faint of heart. Her advice is to first be educated; reading all information and guidance you can glean from other breeders, and then use every resource available. Merry relies on several tools as predictors to help decide when her mares will domino. One device she uses is a refractometer. While it isn’t generally advertised as a foaling predictor, mare owners can predict foaling within 12-24 hours. The procedure is to strip just a drop or two of mare’s milk, place the sample on the screen of the refractomer and then watch for a quick jump on the scale. The refractometer is convenient, using such a small sample and no mixing. It cost around $80. Merry has also used milk test strips distributed as hard water test strips, and these are also a pretty good indicator of impending parturition, but these also are not fool proof. This year Merry used the Maybe Baby test strips for the first time. The strips are convenient with no mixing and are typically easy to use. Her limited experience with them last year was due to user error (she ordered them last year and after testing once, immediately dropped them in the water bucket!). The instructions included indicate when the pH reaches 6.0 foaling SHOULD occur in 1224 hours. Testing on Merry’s mare this year proved otherwise when after six days, foaling was obviously not immediate- even though the refractometer reading was off the chart. 22 Miniature Horse World A P R I L / M AY 2016 Good news for the resulting foal (*passive transfer/IgG), but not the ending Merry had hoped for. *In order to check passive transfer you have to do a blood test, IgG on the foal. However, since the milk itself is testing good to very good, and the foal is nursing well, one could assume it is getting the colostrums, but an IgG test performed by your vet is recommended. An Equine Colostrum Refractometer A refractometer must be calibrated to evaluate mare colostrum. The test is rapid (less than one minute), repeatable, and uses a small volume of colostrum (1-3 drops). The steps involved are: 1. A  small amount of colostrum (i.e. 1 ml) is collected from the mare’s udder. 2. O  ne to two drops of colostrum is applied to the prism surface of the refractometer. 3. The daylight plate is closed, effectively spreading the colostrum across the surface of the prism. 4. View through the eyepiece while holding the refractometer in the direction of a light source. 5. N  ote the level or location of the color (blue) on the scale. The scale contains graduations (%) and a quality assessment score for accurate interpretation. An increase in percentage may indicate foaling within 12-24 hours. By Melissa Powell with Merry Black Within the last eight years, Merry has also incorporated the surveillance abilities of MareStare into her repertoire. As she foals the mares out single-handedly, she admittedly couldn’t do without it, as it’s impossible to watch every mare 24/7. Merry shares, “There are very knowledgeable folks on MareStare, who know what signs to look for and will call at any time, from anywhere and let you know your mare is in labor. Because MareStare is “worldwide” there are “eyes” watching from every time zone to cover times when one needs to get some rest. I have even had a woman from Sweden call me - only it was a false alarm. But I would much rather have a false alarm than something goes wrong and no one call.” Merry’s system consists of several wired cameras and a quad processor so she can watch four mares at once or switch to a single cam as needed. Previous to using MareStare, Merry tried the halter attached baby buzzer or foaling alarms. They work great for other breeders, but for her use it didn’t work well as her mares seemed always to lie flat out to sleep, sounding the (false) alarm way too often. The sew-in type alarms work very well for some farms as well, but another breeder had warned her one mare did rub the sensor out, causing her to miss a foaling when the alarm didn’t go off. Merry is most comfortable using the “all eyes on” method of the watch and wait procedure of foaling. With a mini mare, there are so many things that can go wrong and all in a short amount of time. If hard labor starts AND the water has broken and the foal doesn’t come within 15 minutes you have a problem. Merry says, “I don’t time it, but after a few minutes I will check and see if I feel two feet and a nose. If not, I will try to locate them and reposition if necessary. I have had to find a foot before but have been fortunate that that was all I had to find. Like I said, mini foaling is not for the faint of heart.” Although our MareStare with Merry and her mare, Rosie, started on February 5th
