The Cooperative has been proposing mating plans to its breeders for many years, with the possibility to indicate the desired EBV profiles for the sires to be mated to their individual cows.
However, males re-use their mating organs and by experimentally mating males to many females, we show that the sperm supply is divided between copulations without reloading the pedipalps.
Specifically, mating to too few males may be maladaptive [ 63], whereas mating to too many males may be costly [ 64].
Ms. Palin, of Alaska, has had a rocky time since being named as Senator John McCain's running mate, but to many conservatives her future remains bright.
Another possible contributor to the variable response to daily restricted female access is that the females were not always in estrus, and thus unlikely to be willing to mate for many of the restricted access periods.
The study in question involved the prairie vole, a rodent species whose males are naturally monogamous and enjoy spending time with their partners, and the meadow vole, whose males prefer to mate with many females and then like to wander off and be alone.
Bro-Jørgensen reasoned that female topi, particularly if they have already mated with a less fit male, should want to mate as many times as possible with desirable males to maximize their chances of conceiving high-quality offspring.
Females may wait to be visited by males and do not increase their mobility for finding a mating partner, similar to many other rodents [ 53].
Bubbles, for her part, would probably have been happy to mate with many of her suitors, for while it is in the interest of the alpha to monopolize her, females generally seek to have intercourse with as many of the senior males as possible.
For example, males may seek to mate as many times as possible, whereas a female benefits from less frequent matings that don't stress her nutritional reserves.
