L'activité FSH (test de Steelman et Pohley) et l'effet oestrogénique de l'extrait aqueux du mélange de feuilles d'Aloe buettneri, Dicliptera verticillata, Hibiscus macranthus et Justicia...
Seasonality of reproduction and production in farm fishes, birds and mammals (2007)
Chemineau, P., Malpaux, B., Brillard, J.P., Fostier, A.
A very large majority of farm animals express seasonal variations in their production traits, thus inducing seasonal availability of fresh derived animal products (meat, milk, cheese and eggs). This...

In the ewe, seasonal anestrus results from an increased responsiveness of the hypothalamus to the negative feedback of estradiol (E2) on the gonadotropic axis under long-day conditions. However, this...
Chemineau, P., Daveau, A., Pelletier, J., Malpaux, B., Karsch, F., Viguie, C.
Background: We wanted to determine if changes in the expression of serotonin 2A receptor(5HT2 A receptor) gene in the premammillary hypothalamus are associated with changes in reproductive...
Chemineau, P., Morello, H., Delgadillo, J.A., Malpaux, B.
Resumen Los pequeños rumiantes presentan, como sus ancestros salvajes, un período de reposo sexual estacional de duración e intensidad variable entre razas. Ambos sexos tienen una actividad sexual...
Zarazaga, L. A., Malpaux, B., Chemineau, P.
We investigated if absolute (nocturnal) or relative (ratio nocturnal/diurnal) plasma melatonin concentrations were associated with the seasonal ovulatory activity in Ile-de-France ewes. Ninety-six...

Two experiments were conducted to determine the response of Creole male goats treated with long days and melatonin implants, and the response of the anovulatory does to male effect using males...
Neuroendocrine interactions and seasonality (2002)
Thiery, J.C., Chemineau, P., Hernandez, X., Migaud, M., Malpaux, B.
Abstract Sheep in temperate latitudes are seasonal breeders. Of the different seasonal cues, photoperiod is the most reliable parameter and is used by animals as an indication of the time of the year...
Delgadillo, J.A., Carillo, E., Moran, J., Duarte, G., Chemineau, P., Malpaux, B.
The aim of this study was to determine whether the sexual activity of local male Creole goats in subtropical Mexico can be induced during the non breeding season by a longday treatment followed...
