During December mating periods of 2000-2003, wool and meat breeds crossed with East Friesian milk sheep and rams of prolific breeds (Finn or Romanov) were examined laparoscopically. Ovine ovaries were examined between 4 and 9 days after mating. The litter size was recorded and compared with the number of ovulations. The fertility of the analyzed animals was 69.6%, with 192.6% prolificacy. The d...

Eur J Cardiothorac Surg 2015;48:515. [2] Je HG, Shuman DJ, Ad N. A systematic review of minimally invasive surgical treatment for atrial fibrillation: a comparison of the Cox-Maze procedure, beating-heart epicardial ablation, and ...
Knowledge of epidemiological mechanisms and parameters underlying scrapie transmission in sheep flocks remains very limited at present. Here we introduce a method for fitting stochastic transmission models to outbreak data to estimate bounds on key transmission parameters. We apply this method to data describing an outbreak of scrapie in a closed flock of Romanov sheep. The main findings are th...
Namen prispevka je prikazati neenakomerno in nekoliko naključno plasiranje nekaterih sodobnih slovenskih romanov v bolgarščini. Zanima nas, kolikšni meri infrastruktura kulturnega procesa (prevajalci, založbe, knjižna distribucija, festivali, branja, gostovanja, oglaševanje) odraža avtentično, dostojanstveno reprezentativno podobo slovenske literature, pa gre za rezultat naključja manipulacije....
This study was carried out to identify polymorphisms of BMP15, GDF9 and BMPRIB genes in cross- bred of Romanov×shal sheep. For this reason 79 blood samples were collected from a flock in Gonbad kavous city in Golestan province. DNA was extracted using modified salting out method. Polymerase chain reaction was done by specific primers for amplification of two fragments with 141and 153 bp from ...
The clock gene Period 1 (Per1) may be a prolificacy gene, because it localized to the mouse oocyte and Per1-null drosophila shed fewer eggs. Because Per1 mapped to a region of mouse chromosome 11 syntenic to bovine chromosome 19 where a quantitative trait loci (QTL) for ovulation rate existed, we hypothesized that Per1 influenced folliculogenesis and ovulation rate in ruminants. Ovarian cortex ...
