| Summary: | (Group AP; n = 12). Exogenous progestins were administered 1 2; 83 %) than allantoic puncture (6/12: 50 %). The control affected fetal outcome in the allantoic puncture group. allantoic fluid and treatment with erogenous progestins AP mares with non-viable fetuses. Differences were not as a method of pregnancy reduction in the mare. Mares were aspiration procedures with a tendency (P=0.06) for fetal daily, 30 days) (Group PP; n = 12), or 2) aspiration of death occurred as a result of both allantoic puncture and death rates to be higher following allantoic aspiration (I O/ detected between treatment groups for mean plasma detected if a single fetus remained viable following the erogenous progestins (control; Group C; n=4). Pregnancy Fetal death rate was increased (P=0.01) when the allantois fetuses than in Group PP mares with viable fetuses or Group mummified fetuses occurred more often (P=0.03) in mares of gestation: 1) needle puncture of allantois and treatment on all mares with non-viable fetuses 30 days following one week following treatment and weekly for three additional procedure did not result in fetal death. Day of treatment progesterone concentration. progestin treaunent (Group NP; n=8), or 4) ultrasonography puncture or aspiration of the allantois without erogenous Quarter Horse-type mares (n=36) were used to investigate randomly assigned to one of two treatment groups at Day 40-50 status was monitored using transrectal ultrasonography for termination of a twin. For comparative purposes, two to simulate elevated progesterone concentrations, as would be transvaginal ultrasonographically-guided allantoic aspiration treated with exogenous progestins than in mares not treated treatment groups were added during the second year: 3) treatment to identify and retrieve mummified fetuses. Fetal was higher (P=0.05) for mares in Group PP with non-viable was punctured between Days 40-44 of gestation as compared weeks. Intrauterine endoscopic examinations were performed with Days 4550 of gestation. Following fetal death, retained with erogenous progestins (Altrenogest, 22 mg, per os, once with exogenous progestins.
