RESUMO
Forty-one Day 5.0 to Day 5.5 embryos and one unfertilized ovum were recovered nonsurgically from 24 superovulated, parous buffalo (Bubalus bubalis ) and transferred nonsurgically to 28 synchronized recipients by a team of Bulgarian and American scientists. Five pregnancies were established and four live buffalo calves were born at the end of normal gestation periods.
RESUMO
Cattle grazing St. Augustine grass growing on peaty muck soils in the Florida Everglades developed anemia associated with the presence of Heinz bodies and suboptimal concentrations of selenium in blood. Selenium supplementation corrected the anemia, prevented Heinz body formation, increased the body weight of cows and calves, and elevated blood selenium. This may be the first recorded example of widespread anemia in a population due to selenium deficiency.

A normal, live 35-kg water buffalo bull calf was born 300 days after it was nonsurgically collected as a 7-day blastocyst from a water buffalo donor and transferred nonsurgically to an unrelated water buffalo recipient. The development of estrus synchronization, superovulation and estrus detection methods in water buffalo are described.
