In the Carpathian Basin the wild boar (Sus scrofa) belongs among the most important game species both ecologically and economically, therefore knowing more about the basics of the genetics of the species is a key factor for accurate and sustainable management of its population. The aim of this study was to estimate the genetic diversity and to elucidate the genetic structure and location of wild boar populations in the Carpathian Basin. A total of 486 samples were collected and genotyped using 13 STR markers. The number of alleles varied between 4 and 14, at 9 of the 13 loci the observed heterozygosity was significantly different (p < 0.05) from the expected value, showing remarkable introgression in the population. The population was separated into two groups, with an Fst value of 0.03, suggesting the presence of two subpopulations. The first group included 147 individuals from the north-eastern part of Hungary, whereas the second group included 339 samples collected west and south of the first group. The two subpopulations’ genetic indices are roughly similar. The lack of physical barriers between the two groups indicates that the genetic difference is most likely caused by the high reproduction rate and large home range of the wild boars, or by some genetic traces’ having been preserved from both the last ice age and the period before the Hungarian water regulation.

Penelitian ini bertujuan untuk mengetahui kadar estradiol 17-β dan gambaran dinamika folikel yang menyertai kejadian siklus estrus yang pendek Penelitian ini menggunakan 7 ekor sapi Bali yang ada di Kebun Pengembangan Penelitian Pertanian, dan Peternakan (KP4), betina, umur 2 tahun, sehat dan bersiklus estrus normal. Pengukuran diameter folikel menggunakan ultrasonografi (USG) dan darah diambil dari vena jugularus dimulai hari pertama setiap hari dalam waktu yang bersamaan selama 3 siklus. Kadar estradiol 17-β dianalisis menggunakan metode Enzyme Immuno Assay (EIA) Hasil penelitian menunjukkan 4 ekor sapi Bali mempunyai siklus estrus pendek (n=7) diantara siklus estrus normal. Sapi Bali tersebut mempunyai 1 gelombang perkembangan folikel dengan panjang siklus 7-10 hari, diameter folikel ovulasi maksimal dan kadar estradiol 17-β menyerupai siklus normal. Kadar tertinggi estradiol 17-β pada siklus tersebut 107,77 ± 55.94 pg/ml pada hari ke 7-10 saat ukuran folikel ovulasi mencapai 10.5 ± 0,38 mm. Kesimpulan penelitian ini adalah kejadian siklus estrus pendek dapat terjadi diantara siklus normal pada sapi Bali.
