Abstract:
Ongole crossbred (CO) is a local cow that has long been bred in Indonesia. One strategy to
increase population is to produce frozen semen with good quality. Semen production is
influenced by libido which is known through male sexual behavior. The purpose of this study
was to determine the effect of sexual behavior on semen production. The research material
included 3 OC cattle studs aged 4-5 years with a body weight of 500-600 kg. Semen is
collected twice a week using the artificial vaginal method. The method used in the study was
observational. Sexual behavior parameters include libido and ejaculation duration. Semen
production variables are known by calculating total spermatozoa and total motile
spermatozoa. Data were analyzed using Randomized Block Design (RBD) consisting of 3
treatments and 10 replications. If there is a difference, continue with Duncan's Multiple
Distance Test. The relationship between sexual behavior and semen production was
calculated by Pearson correlation and its effect was calculated by linear regression. The
results showed that the length of libido was not significant (P> 0.05), the duration of
ejaculation was significantly (P <0.01), the total spermatozoa was significantly (P <0.01), and
the total motile spermatozoa was significantly (P <0.01) in all three male males. The
relationship between the duration of libido and semen production was insignificant (P> 0.05),
while the duration of ejaculation had a significant relationship (P <0.05) to total spermatozoa
with R2 = 22.15% and total motile spermatozoa with R2 = 25.84 %. The conclusion of the
study was that there was an influence on sexual behavior on semen production in OC cattle
