Control of pulsatile LH secretion during seasonal anoestrus in the ewe.
The seasonality of reproductive activity in the ewe in temperate latitudes is controlled by photoperiod. Its annual variations control the temporal organization of the sexual cycle by changing the activity of the gonadotrophic axis. Cyclic oestrous behaviour usually appears in the ewe at the end of summer or the beginning of autumn and finishes in winter or at the very beginning of spring. Seas...
متن کاملSurvival and hazard functions in the population of David’s deer (Elaphurus davidianus
Survival and hazard functions supply suitable information concerning changes in the population dynamics, especially in the case of species that are not subjected to artificial selection. One of such species is David’s deer (Elaphurus davidianus Milne-Edwards, 1866) that underwent a dramatic reduction in the population size in the first years of the XX century, but has been subsequently restored...
متن کاملDraft genome of the milu (Elaphurus davidianus)
Abstract Background: Milu, also known as Père David's deer (Elaphurus davidianus), had been widely distributed in East Asia but experienced a severe bottleneck (only 18 survived by the end of 19th century), and the current 4500 individual population was propagated from only 11 individuals reared by the 11th British Duke of Bedford. This species is known for its distinguishable appearance, the d...
متن کاملDaily GnRH and LH secretion in ewes is not modified by exogenous melatonin during seasonal anestrus.
The effect of central, short-term melatonin administration on daily GnRH and LH secretion was studied in ewes during seasonal anestrus. Melatonin, in a total dose of 32 micrograms and the vehicle were perfused for 4 hours into the mediobasal hypothalamus/median eminence (MBH/ME). The mean GnRH concentration during perfusion with melatonin decreased significantly (P < 0.05), as compared to the c...
متن کاملA new gene mapping resource: interspecies hybrids between Père David's deer (Elaphurus davidianus) and red deer (Cervus elaphus).
Three male F1 hybrids between Père David's deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 ...
