I found this in a horse breeding article I had saved from Southern Horseman (Oct 2001). I don't always have the time the time to read them immediately, but do save those I want to read later and to have for reference.
Since people were talking about problems with mares and breeding in FL and the SE the past 2 years, and we have had a drought in NC the past 2 years........that this could prove relevant to some breeders.
Getting Your Mares to pay you dividends...
rechecking pregnant mares in the fall for pregnancy...
Mares that were grazing endophyte-infected fescue pastures WHEN MATED may also now be open.
Mares that were in their first4 0 days of pregnancy when dry weather brought on a severe pasture slump, may have not remained pregnant.
Data shows that mares getting low quality nutrition in the first 40 days of gestation can decrease the pregnancy rate or have an early embryonic death.
It suggests having mares rechecked in the fall, if you have poor quality fall pasture or have a shoratge of good quality hay for the winter.
Second-trimester mares still need to be maintained separately and differently than their Open counterparts, especially when they had been lactating in a dry summer. Mares gain about 70% of their weight gain of pregnancy in the second trimester.
I had two come back open in August and September. One is 14 and hasn't had much of a broodmare history..not bred much, but had one foal known of. The other, a well-proven broodmare had a mild bout of founder with a temp change, and had came back in heat the next week. Both had been verified pregnant by ultrasound. Both were bred in June, prior to a long heatwave/drought in July. The first mare, the vet thought the embryo was small...but I have heard that before on Paso embryos. They are used to checking Thoroughbreds, warmbloods and QHs. so no majr biggee, but could of been a factor.
Thoughts.......
