Summary: | It is intended to provide a teat cup by which a large amount of milk can be obtained within a short time directly from udders of a laboratory animal such as a rat, a mouse, a beagle for experimental use or a miniature pig. The inner wall of the teat cup is formed according to the shape of the udder 60 of a laboratory animal. The inner wall size is somewhat larger than the udder 60. Owing to the negative suction pressure of a milking machine, the udder 60, in particular, the conical eminence 62 and the papilla base 63 thereof are adsorbed on the inner wall face. Thus, a stimulus similar to suckling behavior of newborns can be provided so that oxytocin secretion from the posterior lobe of hypophysis can be effectively promoted, thereby providing a large amount of milk in a short time.
L'invention porte sur un gobelet-trayeur permettant d'obtenir en peu de temps une quantité importante de lait directement des mamelles d'un animal de laboratoire (rat, souris, porc nain, etc.). La paroi intérieur du gobelet adaptée à celle de la mamelle (60) de l'animal, présente une largeur légèrement supérieure. Sous l'effet de la dépression de la trayeuse, la mamelle (60), et en particulier l'éminence conique (62) et la base (63) de la papille dont attirées sur la face de la paroi intérieure. On obtient ainsi un stimulus équivalent à celui de la tétée des petits qui provoque la sécrétion d'oxytocine par le lobe postérieur de l'hypophyse et par-là une abondante production de lait en un temps court. |
