Research Notes Cryopreservation of Rooster Semen in Thirteen and Sixteen Percent Glycerol

roosters was cryopreserved with glycerol concentrations of 13 and 16 % in a microprocessor-controlled freezer. Thawing and deglycerolation were facilitated by the use of an improved microprocessor-controlled thawing device and high speed dialyzer. Deglycerolated semen (100 fjL; 192 and 154 million sperm, respectively, for the 13 and 16 % glycerol concentration) was inseminated int
