Existence of synchronization of reproduction at the level of the social group of the European wild boar (Sus scrofa).
Reproductive events were recorded in two groups of female wild boars kept in semi natural conditions. The first group had been kept for 2 consecutive years with a male. Most farrowing took placeExpand

Non-pheromonal stimulation by the male of LH release in the anoestrous ewe
In the anoestrous ewes, the introduction of rams leads to an increase in the secretion of LH and ovulation. Several studies have led to the hypothesis that a ewe's response to the male is mediated byExpand

Effectiveness of testosterone-treated wethers and ewes as teasers
Abstract Two series of experiments were conducted in October 1979 to determine the effectiveness of ewes or castrated male sheep treated with testosterone to induce anovular ewes to commence breedingExpand

Effect of pheromones from male goats on LH-secretion in anoestrous ewes
Pheromones from ram's wool or buckhairs lead to an increase in the LH pulse frequency, thus inducing ovulations in seasonally anoestrous sheep and goats, respectively. Indications exist thatExpand

Non-involvement of the accessory olfactory system in the LH response of anoestrous ewes to male odour.
In anoestrous ewes, male chemosignals elicit rapid increases in luteinizing hormone (LH) secretion that can ultimately lead to ovulation. To assess the possible involvement of the accessoryExpand

Temporal variation in LH and testosterone responses of rams after the introduction of oestrous females during the breeding season.
The response of sexually experienced Ile-de-France rams to the presentation of oestrous females in October at sunrise (Subgroup S) or at 11:00 h (Subgroup N) was studied and compared withExpand

Luteinizing hormone, testosterone and cortisol responses in rams upon presentation of estrous females in the nonbreeding season.
The physiological responses of luteinizing hormone, testosterone and cortisol in sexually experienced Ile de France rams to the introduction of estrous females were studied during the nonbreedingExpand
