摘要:Moringa oleifera (Moringa) leaves contain high levels of nutrition that can be utilized as a feed supplement to increase libido and semen quality. This study was aimed to evaluate the effect of Moringa leaves supplementation on libido and sperm quality of Bali bulls. This study used two-sample t-test on four Bali bulls were kept under individual pens for two periods of eight weeks. During the first period (control), the experimental Bali bulls were fed concentrates (1% of body weight) and rice straw ad libitum. During the second period, the experimental Bali bulls were fed similar to the first period with an additional of Moringa leaves 15% of the weight of the concentrate (treatments). Libido and sperm quality were measured twice a week. Plasma samples were taken three times a day (06:00, 14:00, and 22:00h) on the last day of each period. Plasma testosterone concentrations were analyzed by using ELISA techniques. Variables measured were compared using paired student's t-test. Supplementation of Moringa leaves increased testosterone levels (P<0.05) (4.57 vs 4.79, 0.45 vs 4.78, and 2.35 vs 5.63 ng/mL, respectively during 06.00; 14.00; and 22.00h), increased libido (P<0.05) (7.20±1.49 vs 3.49±0.40 min), and increased both the total motility (P<0.05) (63.99±3.37% vs 84.96±3.09%) and the progressive motility (P<0.05) (52.77±1.76% vs 67.03±3.74%) of sperm. Supplementation of Moringa leaves also increased (P<0.05) the velocity and the amplitude and decreased (P<0.05) the linearity of sperm. It can be concluded that the supplementation of Moringa leaves could increase plasma testosterone concentrations, libido, and sperm motility of Bali bulls.
其他摘要:Daun kelor mengandung nutrien yang tinggi sehingga dapat dimanfaatkan sebagai bahan pakan tambahan untuk meningkatkan libido dan kualitas semen. Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi daun kelor terhadap libido dan kualitas sperma pejantan sapi Bali. Penelitian ini menggunakan uji perbandingan dua nilai tengah terhadap 4 ekor pejantan sapi bali yang dipelihara secara intensif pada kandang individual selama 2 periode, masing-masing 8 minggu. Pada periode pertama (kontrol), sapi pejantan diberi pakan konsentrat 1% bobot badan dan jerami padi secara ad libitum. Pada periode kedua, sapi pejantan tersebut diberi pakan yang sama dengan pada periode pertama dengan tambahan daun kelor 15% dari bobot konsentrat (perlakuan). Libido dan kualitas sperma diukur 2 kali seminggu. Sampel plasma diambil 3 kali sehari (pukul 06.00, 14.00, dan 22.00) pada hari terakhir setiap periode. Konsentrasi testosteron dalam plasma dianalisis dengan menggunakan teknik ELISA. Peubah yang diukur dibandingkan dengan menggunakan uji t berpasangan (paired student’s t-test). Suplementasi daun kelor meningkatkan kadar hormon testosteron dalam plasma (P<0,05) (4,57 vs 4,79; 0,45 vs 4,78; dan 2,35 vs 5,63 ng/mL), masing-masing pada pukul 06.00, 14.00, dan 22.00), meningkatkan libido (P<0.05) (7,20±1,49 vs 3,49±0,40 menit), dan meningkatkan motilitas total (P<0.05) (63,99±3,37% vs 84,96 ± 3,09%) dan motilitas progresif (P<0.05) (52,77±1,76% vs 67,03±3,74%) sperma pejantan sapi bali. Suplementasi daun kelor juga meningkatkan (P<0,05) kecepatan dan amplitudo, serta menurunkan (P<0,05) linearitas sperma. Dapat disimpulkan bahwa suplementasi daun kelor dapat meningkatkan kadar hormon testosteron dalam plasma, libido, dan motilitas sperma pejantan sapi bali.
