Mated males were dissected at fixed times following this mating period (0 hours, 2 hours, 8 hours, 24 hours and 48 hours) and the sizes of their testes and accessory glands were compared to unmated control males.
Due to the possibility of using multiple sires in JIVET, three separate matings were assigned to females for JIVET in the same mating period, whereas AI/N and MOET females only received one mating.
Individuals in the sample are the male offspring produced by females from experimental groups that differed in population density during the pre-mating period (PM), and in the number of possible mates during the mating period (M).
Females were assigned to experimental groups that differed in population density during the pre-mating period (PM), and in the number of possible mates during the mating period (M).
Cows were fed these diets for 92 days on average, from calving until three weeks into the mating period.
Ground vibrations may be used to warn one another of danger, and also to find mates during an elephant's very brief mating period.
Selection for harvest weight in GIFT should improve spawning success of Nile tilapia, provided the mating period is limited to 20 32 days.
Females may solicit copulations from multiple males and receive sperm one or two times an hour during their 10-day mating period.
Female A129 mice were infected with 103 p.f.u. of DN-1, DN-2 or H/PF/2013 intravenously (i.v.) 6 days after a 4-day mating period and killed at 7 days post infection (Fig. 9a).
If bears are roaming-to-mate, we predicted greater range size and daily displacement, and more linear movements for receptive animals during the mating period compared to post-mating.
Other male moths are then attracted to the males that smell like females and try to mate with them, wasting time and effort during their limited mating period.
