Effect of split ejaculation and seminal extenders on longevity of donkey semen preserved at 5° C Arq. Bras. Med. Vet. Zootec.
Mello,S.L.V.; Henry,M.; Souza,M.C.; Oliveira,S.M.P..
The aim of this study was to evaluate the longevity of donkey sperm comparing the rich seminal fraction and the whole semen in two extenders, Kenney and modified Baken extenders. Semen of five donkeys were collected through an open-end artificial vagina once a week for five consecutive weeks. The two first jets (rich fraction) of semen were collected separately from the rest of the ejaculate. Whole semen samples were obtained mixing proportionally part of the rich with part of the poor seminal fractions. Seminal samples were immediately diluted 1:1 in each extender and maintained at room temperature during sperm concentration analysis. Samples were further diluted to rich 50×10(6) sperm per ml, cooled in a refrigerator at the initial rate of -0.6° C/min...
