Tenability of ram semen

Storage of ram semen.

Storage of ram semen in liquid and frozen state, the diluents used for both methods, processing, cooling, freezing and thawing of semen are reviewed. Factors influencing the fertility of stored semen and methods used for improvement are discussed, and fertility results of long-term frozen stored ram semen are also given.

The Use of Formalin in the Storage of Ram Semen

A calcium-free Krebs Ringer solution, supplemented with 1 mg/ml glucose, with or without 0.025% formalin, was used to dilute freshly collected ram semen on a 1:l basis. The treated semen was inseminated into the cervix of Merino ewes either within 60 minutes of collection or after storage at 5OC for 24 h. Although the Ringer-formalin diluent always caused complete immobilisation of the spermato...

Tenability Pursuit

Recently Hájek prophesied that “as fans of the Friday the 13th series know, you should never be surprised if Jason suddenly reappears in a new guise – and the same is true for Stalnaker’s Thesis” (Hájek, 2011, p. 14). So what better day to pick for a plea for the thesis than today? Obviously, a new guise is also needed for the thesis; it cannot live on in the way as it is understood in the triv...

The relationship between semen quality and mineral composition of semen in various ram breeds.

Semen was collected during the breeding season from rams by electroejaculation from two native (13 Najdi and 8 Naemi) and three imported (6 Merino, 7 Somalian and 9 Sudanese) sheep breeds. There was a marked reduction in sperm concentration and the percentage live spermatozoa (p<0.01) produced by the Somalian (Barbari) and Sudanese (Sawakni) breeds. On the other hand, these two breeds showed th...
