Document Summary
Can build timeline about when animals will be going into labour. Make sure people are available to help out. Having similar groups you can control exposure to pathogens. Most likely they are in luteal phase and manage that way. Instead of trying to sync them in the follicular. Back of vaginal wall will absorb the drugs. Spring loaded y-shape keeps it in and touches the vagina. As soon as you remove it the progesterone will drop off (as long as they don"t have a cl) Make sure to give pgf2 alpha a day before the removal to regress any cl that may be. Then after extraction the cow will go into heat. How much progesterone to maintain cl differs between species. Hard to get enough progesterone in pigs through a vaginal insertion. Horses have too big of a vagina so on this too. Sometimes you give it after they are bred to help maintain progesterone until placenta can take over.
