Quality and fertility of cooled rabbit semen supplemented with cyclic-AMP stimulators

Autor: M.N. El-Gaafary

Publikováno v: Animal Reproduction Science. 34:307-313

Semen was collected from ten New Zealand White bucks by means of an artificial vagina. Ejaculates exhibiting active progressive motility and high concentration were pooled, diluted with Tris-based diluent, cooled to 5°C over 2 h and stored at this t

Re-activated bull spermatozoa: motility, acrosome status and ability to penetrate cervical mucus and zona-free hamster oocytes

Autor: C.N. Graves, M.N. El-Gaafary, Paulo Bayard Dias Gonçalves

Publikováno v: Animal Reproduction Science. 32:163-172

Semen of four dairy bulls was inactivated by centrifugation twice through a 7% Ficoll solution. After the second centrifugation, the sperm fractions were resuspended in 14G buffer and stored for 0, 3, 6 and 9 days at room temperature. At the end of e

Effects of caffeine on bull semen quality and sperm penetration into cervical mucus

Autor: A. H. Daader, A. Ziedan, M.N. El-Gaafary

Publikováno v: Animal Reproduction Science. 23:13-19

Tris-based diluent is superior to citrate-based diluent for bull semen dilution. Caffeine (1,3,7-trimethyl-2,6-dioxy-purine), a cyclic nucleotide phosphodiestrase inhibitor, maintained good semen criteria when added to the semen at levels of 10 and 2

Artificial insemination

Autor: R.F.E. Axford, A.G. Chamberlain, M.N. El-Gaafary

The success of artificial insemination of sheep depends on various factors that act in a complex way. These include quality of semen, sperm cell count per dose, the timing of oestrus in sheep, number of inseminations, time of insemination and site of
