The proportion of transferable beef embryos obtained after superovulation, follicle aspiration, and in vitro maturation and fertilization has been small. To seek possible explanations, cows on different planes of nutrition were treated with exogenous

To test the hypothesis that bull antisperm antibodies have the capacity to interfere with fertilization, antisperm antibodies were generated in three 13-mo-old Holstein bulls by auto-immunizing each bull with sperm three times. All bulls produced ser

Changes in the plasma membrane of bovine sperm during heparin-induced capcitation were detected by the binding of fluorescent labeled lectins to unfixed sperm. Of the seven lectins evaluated, only binding of wheat germ agglutinin (WGA) changed with c

Eight different lectins conjugated to fluorescein isothiocyanate (FITC) were used to screen for sperm plasma membrane changes during in vitro capacitation of bovine sperm. Analysis of lectin binding to sperm was done using flow cytometry. Of the eigh

The objective of this study was to determine whether the initiation and length of the zygotic S-phase differs for embryos sired by bulls demonstrating high versus low fertility in vivo. Bovine oocytes were matured in vitro for 24-27 h and fertilized

The objective of this study was to investigate the importance of cAMP during capacitation of bovine sperm. The competitive antagonist of cAMP, Rp-adenosine-3'5'-cyclic monophosphorothioate (Rp-cAMP), blocked heparin-induced capacitation (p0.05). The

Fourier harmonic analysis (FHA) of sperm nuclei is a precise and objective method to evaluate shape of the sperm head, with the calculated harmonic amplitudes highly related to male fertility. The FHA approach has been developed for use in the bull a

Incubation of bull sperm with liposomes made with phosphatidylcholine (PC) containing fatty acyl chains of either 10 (PC10) or 12 (PC12) carbons resulted in greater than 90% of the sperm exhibiting an acrosome reaction (AR) within 15 min. Liposomes o

The effect of equipment design, separatory media, and time and temperature of separation were studied. Discontinuous 4%/10% bovine serum albumin (BSA) gradients were used to isolate highly motile spermatozoa in rabbit and bull semen. For all conditio
