Abstract
Four healthy mature bucks of Zaraibi breed were used in this study. Semen samples were collected twice weekly using Electro-ejaculator. Samples with Progressive motility (>80%), total abnormalities (<10%). Five extenders were used, Tris 2.5 % egg yolk extender with 5 ml glycerol as a control, and substitution of whole egg yolk with 4, 6, 8 and10% low density lipoprotein (LDL), respectively. Semen was diluted to 200x106 sperm/ml, and refrigerated (5°C) for three hours, prior to storage in liquid nitrogen (LN) for one week. Sperm progressive motility, life sperm, intact acrosome, plasma membrane integrity and abnormalities were assesd at post-thawing (at 37°C for 30 sec.). The LDL extenders were more effective in preservation of progressive motility, intact acrosome and integrity of the plasma membrane of buck spermatozoa than whole egg yolk extender. Sperm progressive motility, intact acrosome and plasma membrane integrity were much higher (P< 0.05) in the 8 % LDL extender (53.50, 54.64, 54.11) vs. (31.0, 26.31, 37.25) in the control 2.5% egg yolk. It was concluded that LDL 8% in extender improved the freezability of buck spermatozoa.

Key words: LDL,freezing, buck semen
