Pengaruh Suplementasi Vitamin E, Mineral Selenium dan Zink Terhadap Konsumsi Nutrien, Produksi dan Kualitas Semen Sapi Simental
ABSTRACT: Simental bulls often
experience a decline in production and semen quality in the rainy season, which
have a higher humidity and high rainfall. This study aims to maintain nutrient
consumption, production and semen quality Simental bulls during the rainy
season through the supplementation of Vitamin E, Selenium and Zinc Minerals.
The study was conducted in July-December 2012 at the Artificial Insemination
Center (BIB) Unggaran. The research material used in this study were 12 males
Simental cows BIB Unggaran grouped by age. The experimental design used in this
study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit.
E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as
replicates. Parameters measured were dry matter intake and nutrient
consumption, production and semen quality. Cement production was measured from
fresh semen volume during the study, whereas semen quality measured motility
and concentration of spermatozoa from fresh semen. Data consumption of dry
matter and nutrient intake obtained were processed using analysis of variance,
followed by Duncan test. While data on production and semen quality were
analyzed descriptively. The results showed that the combination of vitamin E
supplementation, minerals Selenium and Zinc did not affect dry matter intake,
total digestible nutriens and crude protein, but resulted in a decrease in the
percentage of shelter, semen volume, sperm motility and concentration smaller
than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the
number of shelter respectively 41,55%, 19,56% and 13,63% compared to before
treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and
40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased by
55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm
motility, sperm concentration in treatment T , T2 and T3, respectively
decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of
vitamin E supplementation, minerals Selenium and Zinc can prevent the decline
in cement production, sperm motility and sperm concentration Simental bulls
during the rainy season.
