PENGARUH PENAMBAHAN VITAMIN E DAN MINERAL Zn TERHADAP KUALITAS SEMEN SERTA FERTILITAS DAN DAYA TETAS TELUR KALKUN LOKAL [The Effect of Vitamin E and Zinc Suplementation on the Quality of Semen, Egg Fertility and Hatchability of Local Turkey]

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh penambahan vitamin E dan mineral Zn terhadap kualitas semen serta fertilitas dan daya tetas telur kalkun lokal. Penelitian menggunakan 16 ekor kalkun jantan dan 16 ekor kalkun betina. Penelitian disusun berdasarkan rancangan acak lengkap dengan 4 perlakuan : perlakuan kontrol (P0), penambahan vitamin E (P1), penambahan mineral Zn (P2), penambahan vitamin E dan mineral Zn (P3). Data yang diamati meliputi volume semen, motilitas, konsentrasi, persentase sperma hidup, dan persentase sperma abnormal untuk kalkun jantan. Pada kalkun betina diamati fertilitas dan daya tetas telur. Data hasil penelitian dianalisis ragam dan dilanjutkan uji beda nyata terkecil untuk peubah yang berbeda nyata. Hasil penelitian menunjukkan bahwa penambahan vitamin E dan mineral Zn memberikan pengaruh sangat nyata terhadap motilitas, konsentrasi, persentase sperma abnormal, fertilitas dan daya tetas serta berpengaruh nyata terhadap volume semen dan persentase sperma hidup. Pemberian vitamin E dan mineral Zn secara bersamaan memberikan kualitas semen, fertilitas dan daya tetas telur kalkun lokal yang terbaik.

Sixteen male and 16 female local turkey werw evaluated throughout the experiment. The treatments were P0 (control), P1 (supplementation of vitamin A), P2 (supplementation of zinc), and P3 (both supplementation of vitamin E and zinc). The treatments were arranged to a completely random design with 4 replications. Parameters observed of male turkey were semen volume, motility of spermatozoa, concentration of spermatozoa, percentage of spermatozoa, liveability of spermatozoa. and spermatozoa abnormality. Parameters observed of female turkey were the fertility and hatchability of her eggs. The data were analyzed using analysis of varians and then were tested using least significant defferent. The results showed that both supplementation of vitamin E and zinc had significant effects on motility, concentration, abnormal of sperm, % life of sperm, fertility and hatchability of eggs. The combination of vitamin E and zinc supplementation gave the best effect on the parameters observed. Keywords : local turkey, vitamin E, zinc, quality of semen, egg fertility, egg hatchability
