Guidelines come supplemental lightingAdd supplemental bright in the evening and also in the winter till 11 p.m.Provide 16 hrs of consistent lighting daily.Use a 200-watt incandescent bulb or 2 40-watt fluorescent tubes; you should have the ability to comfortably review a newspaper everywhere in the stall.Expose pregnant mares, due at an early stage in the season, come lighting as they may stop cycling following their foal heat.

Rule out infections

Many stud farms require a uterine society (pre-breeding swab) on open up mares to preeminence out infection. Uterine cultures can additionally benefit the mare owner by identifying undiagnosed infection. Infections deserve to waste several warm cycles.

Occasionally, maiden windsucking mares will have actually an infection. For much more information on windsucking and also other unwanted behaviors see undesirable behaviors and vices in horses. A finish veterinary exam of the reproductive street can inspect these mares for injuries and also structural defects that influence fertility and also cycling.

During pregnancy

Feed your mare to maintain moderate to good body condition throughout pregnancy and lactation. You can expect your mare to acquire 9 to 12 percent of she body weight during pregnancy.

However neither of this forages will meet her enhanced need for phosphorus. Grass forages will likewise be as well low in calcium. To correct this, mares need to receive a day-to-day salt-calcium-phosphorus mineral mix supplement. You can purchase supplements details to the kind of forage friend feed.

Supplement v vitamins and also trace minerals for fetal development. Copper, zinc, manganese, and also iron space stored in the fetal liver. Research shows mares that did not obtain a copper complement in the last trimester had less sound foals than mares the did acquire copper. Feeding supplemental copper come the education foals no correct the problems.

Give mares herbal vitamin E daily, 30 days before foaling, to boost the passive carry of antibodies from mare to foal.

During lactation

Once lactation starts, the mare"s energy and protein needs boost further. High quality forage with a mineral supplement can fulfill these needs, yet most mares should also receive a grain/protein mix. You can feed these mixes about 0.5 come 1 lb per 100 pounds the body load daily.
