ANALISIS KUALITAS SEMEN BEKU SAPI SIMMENTAL MENGGUNAKAN PENGENCER ANDROMED® DENGAN VARIASI WAKTU PRE FREEZING
ABSTRACT: The goals of
research was to know the effect of pre freezing time to the frozen semen
quality ofSimmental and the best time of pre freezing that can preserve the
frozen semen quality of Simmental.This study was conducted in Regional
Technical Service Unit - Regional Artificial InseminationOffice Lampung,
Terbanggi Besar District, Central Lampung Regency, Lampung Province on 7th
–13th April 2014. The completely randomized design was used in this research
with 5 treatments (5minutes; 6 minutes; 7 minutes; 8 minutes; 9 minutes) and 4
times of replication. The data wereanalyzed using analysis of variance and then
continued with orthogonal polynomial test.The results showed that the time of
pre freezing did not affect significantly (P> 0.05) on thepercentage of
sperm motility and the percentage of life sperm after pre freezing, but the
effect wassignificant (P <0.01) on the percentage of sperm motility and
percentage of life sperm post thawing.Orthogonal polynomial test showed that
the effect of pre- freezing time on the percentage of spermmotility and
percentage of life sperm after thawing had linear pattern with each equation
those were Y= -28,88+7,38X and Y = -24,97+8,09X. Pre freezing for 9 minutes was
able to show the percentage ofsperm motility and percentage of life sperm after
thawing better than the pre freezing for 5 − 8minutes.
