Abstract:
Madura cattle are Indonesian native germplasm which
has a high productivity. Madura bulls used for artificial insemination
programs must be superior bulls with a high libido and semen
production. The libido can be seen through the sexual behavior of the
bulls before semen collection. The purpose of this study was to
determine the relationship between sexual behavior and semen
production in Madura bulls. This research was conducted on
February 20 until April 25, 2018, at the Laboratory of Singosari
National Artificial Insemination Center, Malang. The materials used
were 4 Madura bulls aged at 8 to 11 years. The parameters observed
were sexual behavior (libido duration and ejaculation duration) and
semen production (total spermatozoa and total motile spermatozoa).
The method used was observational in a randomized block design.
The results showed that the individual bulls had no significant
differences (P>0.05) on libido duration and ejaculation duration, but
had a highly significant difference (P<0.01) on total spermatozoa
and total motile spermatozoa. The highest libido duration was
observed in the Kanwa bull with an average of 2.45±3.41 minutes.
Meanwhile, the highest ejaculation, total spermatozoa, and total
motile spermatozoa were found in the Pasean bull with an average of
7.17±1.60 minutes, 7,374.2±1,888.05 million/ejaculate, and
5,133.52±1,359.65 million/ejaculate, respectively. It could be
concluded that there are no differences in sexual behavior among
individual Madura bulls, however, there are differences in
spermatozoa production. In addition, the sexual behavior stimulation
could increase spermatozoa production.
