الملخص EN

This study was carried out at Research Station, and laboratory, Animal Production Dept.

, Agric.

College, Al-Muthanna Univ.

, during /2016 to 2017 to improve the quality of cryopreservation semen goats by identifying the best concentration of soy milk and comparing it to Egg yolk, besides glycerol 7% was used as a check treatment.

The results showed a significant superiority( P≤0.05) for the TFCSM (Consists of tristtmen 3.63 g/100 ml, fructose 0.5 g/100 ml and citric acid 1.99 g/100 ml+5% soy milk) and difference in cry protectants results.

G7% with TFCSM showed significant superiority( P≤0.05) in the percentage of progressive motility Type A, the non-progressive motility type D, Agglutination, live sperm with averages 18.88, 45.44, 3.86 and 76.50, respectively.

The EG5% with TFCSM showed significant superiority( P≤0.05) in the percentage of progressive motility type A and B, the non-progressive motility type C and D and the percentage of normal sperm, with averages 17.76, 20.15, 15.82, 45.64 and 88.51, respectively.
