Saisonnalité de la reproduction et de la production chez les poissons, oiseaux et mammifères d’élevage

Abstract: Les diverses productions issues d’animaux d’élevage sont fréquemment saisonnières, et par là même leur disponibilité en produits frais sur les marchés (viandes, lait et fromages, oeufs). Ceci relève, en partie, de la décision de l’éleveur qui vise à commercialiser ses produits à la période la plus favorable. Cette saisonnalité peut être aussi imposée par l’accès à des ressources alimentaires saisonnières, comme chez les herbivores, ou par des contraintes biologiques spécifiques, comme celle de la température d… Show more

“…In relation with laying rates and feed conversion ratios, it can be noted that the use of artificial light to increase the lighting length shows some positive effects on the former variables. These results are similar to those of Sauveur [9,10] as well as to those of Galéa et al [11], Thiele [12], Chemineau et al [13] and of Fellah Trade [14]. The likely reason of this variation could be bound to the more active and persistent neurohormonal mechanisms among animals treated with a longer lighting length.…”

“…Improving the productivity of sheep farming goes hand in hand with the control of reproduction and the improvement of its performances. It allows choosing the period of farrowing, reducing the unproductive periods and optimizing the size of the embryo (Chemineau, 1996). Some authors advocate the genetic pathway and argue that it can be obtained by selection or by crossing.…”
