  • sows
  • This project is focused on evaluating existing methods of oestrus detection and developing new ones that will enable producers to quickly and easily determine the optimal time of AI for their sows and gilts. (edu.au)
  • Typically, sows were weaned on Thursdays and oestrus detection was conducted in the presence of a boar once a day from Monday vto Wednesday. (biomedcentral.com)
  • onset
  • Using a mounting detecting device, researchers determined that P/AI was greatest when the interval from first mount (onset of estrus) to AI was 4 to 12 hours 1 . (umn.edu)
  • 16 hours after onset of estrus) may reduce P/AI because by the time sperm cells are ready for fertilization there would be no viable egg to be fertilized. (umn.edu)
  • Of particular interest is the timing of AI in relation to the onset of estrus. (umn.edu)
  • Actually, researchers demonstrated that P/AI of Jersey heifers inseminated with sex-sorted semen was greatest when AI occurred approximately 16 to 24 hours after the onset of estrus (12 to 16 hours = 37.7%, 16.1 to 20 hours = 51.8%, 20.1 to 24 hours = 55.6%, 24.1 to 30 hours = 45.5%) 4 .

  • vaginal
  • To date, there are no reports of the detection of Simonsiella spp in the vaginal flora of any felid. (up.ac.za)
  • Oestrus was identified by typical female reproductive behaviours, as well as by enlarged and separated vulvar lips, and a predominant proportion of superficial cornified cells, clearing of the background, and high bacterial presence in the vaginal smear. (up.ac.za)
  • Simonsiellaspp were identified by their characteristic morphology in 58% (60 of 103) of the vaginal samples collected during oestrus. (up.ac.za)
  • Additionally, Simonsiellaspp were opportunistically found in a vaginal smear from a zoo housed female Sri Lankan leopard in oestrus, during a routine reproduction assessment. (up.ac.za)
  • interval
  • In the month prior to observation, a commercial 2500-sow unit experienced an increase in the wean-to-estrus interval and reduced conception rates. (aasv.org)
  • cycle
  • For this reason, the estrus cycle is currently monitored using 24-hour surveillance cameras and acceleration sensors. (kyocera.co.uk)
  • If the cow is not observed to enter back into estrus approximately 21 days after end of the previous cycle, it is highly possible the cow is pregnant. (mom.me)
  • show
  • Some mares may not show estrus when being actively teased by the stallion but may do so as the stallion moves away. (extension.org)
  • However, no conclusive published data show temporal changes in putative sex pheromone levels during estrus. (diva-portal.org)
  • producers
  • Consequently, avoiding "missed estrus" is a priority among livestock producers, and an area offering great potential for improvement. (kyocera.co.uk)
  • System
  • 10. A remote monitor system for animals according to claim 9, wherein said bolus further includes means for encoding the data burst signal with error detection and correction parameters and said processing means includes means for performing error detection and correction on received data burst signals. (google.com)
  • The proposed system includes a detection and classification model that arranges three binary-classifier support vector machines (SVMs) hierarchically. (thefreelibrary.com)
  • changes
  • A control programme was recommended based on management changes involving oestrus detection, movement of gilts post-service, hygiene in the service area, boar exposure post-service and urinary acidification. (biomedcentral.com)
