She may frequently raise her tail and urinate. She may kick at her belly, pace, lie down and get up, look or bite at her flanks and sweat. "Waxing" of the teats occurs (a yellowish, honey-like secretion appears one to four days prior to foaling).The teats become engorged four to six days prior to foaling.The tailhead may become more prominent a few days prior to foaling. The muscles of the vulva and croup relax.The mare's udder begins filling with milk two to four weeks prior to foaling.The following is a general guideline, but be prepared for surprises: Some mares may show all the signs like clockwork, others show practically none. However, the timetable is far from absolute. Mares provide clues that they will soon give birth. Remove manure and soiled bedding promptly and disinfect the stall between deliveries. Straw (particularly wheat straw) is preferable to shavings, as it won't cling to the wet newborn or mare the way small wood particles can. Dirt or clay floors make sanitation more difficult. If possible, the stall should have adequate bedding and a floor that can be readily cleaned and disinfected. Should you choose to foal your mare in a stall, provide one that is a minimum of 14' x 14'. However, many owners prefer to confine the mare to observe her progress. You won't have to worry about the mare crowding into a corner or foaling too close to a wall. An open grassy area is likely to be cleaner than a stall and provides a healthy environment with adequate room to foal. Allowing the mare to foal in the pasture even has some advantages. Horses have been giving birth on the open range for eons, and this is still an acceptable choice. What your mare will need, however, is a clean, safe, quiet place to foal. It is advisable to have your veterinarian's telephone number nearby in case of an emergency. Hiring a foaling attendant, installing a video monitor or using a birth alarm system can save the life of the foal if a problem should arise. Mares seem to prefer to foal at night in privacy, and apparently have some control over their delivery. In most cases, you will simply need to be a quiet observer. Every effort should be made to be present during foaling. Labor and delivery, while momentous, are generally uncomplicated. It appears, therefore, that binding of apotransferrin to macrophages may not be essential for iron excretion by the cells.If your mare has made it through 11 months of pregnancy, you're almost home free. Pronase treatment of macrophages, which abolishes their ability to bind transferrin, depresses iron release no more than 10–15%. The absence of apotransferrin depresses iron release only slightly, with much of the iron then released in a form readily available to the protein in vitro. No distinct preference of released iron for either site of transferrin could be observed. When apotransferrin is present in the culture medium, from 39% to 72% of iron released from macrophages is bound to the protein, with most of the remainder in a ferritin‐like form. Summary, Rat peritoneal macrophages are capable, in vitro, of processing and releasing iron derived from phagocytosed, immunosensitized red cells, From 20% to 60% of the red cell iron can be returned to the culture medium in 24 h, with resident macrophages more active than inflammatory, peptone‐induced macrophages.
