As short chain fatty acids produced in the forestomach are insufficient to satisfy the energy requirements of the concentrate selecting roe deer (Capreolus capreolus), it is proposed that these animals may have other mechanisms to avoid energy losses due to microbial fermentation. Nutrients bypassing down the ventricular groove (rumen bypass) or ruminal(More)
Geometry is the study of shape and space. Without spatial ability, students cannot fully appreciate the natural world. Spatial ability is also very important for work in various fields such as computer graphics, engineering, architecture, and cartography. A number of studies have demonstrated that technology has an important potential to develop spatial(More)
Plasma 13,14-dihydro-15-keto prostaglandin F2alpha (PGFM) and progesterone levels were determined in actively ovulating, 1- to 2-yr-old female geese (Anser anser domesticus) at hourly intervals during the oviposition cycle, using the enzyme immunoassay (EIA) technique. The plasma PGFM concentration showed a peak at the time of oviposition and decreased to a(More)
Migraine attacks increase during the perimenstrual period in approximately half of female migraineurs. There are differences in the pathogenesis and clinical features of menstrually related and non-menstrual migraine attacks. The objective of this study was to compare the characteristics of migraine in patients with menstrually related and non-menstrual(More)
Twenty-one maiden and 29 pluriparous milking Ankara Saanen goats received either two i.m. injections of PGF(2)alpha (n=25) or intravaginal MAP sponges (n=25) early in November at the start of the breeding season. About twice as many pluriparous goats as maiden goats exhibited estrus after either treatment (87% vs. 47%). Breeding after this induced estrus(More)
