It didn't hurt me when i was young ! :cboy:kjerckie":u7hxdbii said:Does it harm the bull, mentally or physically, to breed at an early age? I read that you shouldn't (on purpose) before he is a year.
How soon after or how far after the bull gets in with the heifer can this shot be adminsistred :roll: ?txshowmom":3a1jrk7f said:She may be bred then. Give her a shot of Lutlyce if you don't want her bred.
txshowmom":1910bgtq said:Two products for aborting heifers are Lutalyse and Estrumate. Both products induce regression of the corpus luteum. The corpus luteum produces progesterone, a hormone that aids in maintaining pregnancy. However, these products are less effective after 120 days of pregnancy because progesterone is being produced by the uterus at this stage.
Studies indicate that a deep intramuscular injection of 25 milligrams of Lutalyse to feedlot heifers at 100 days of gestation or less aborts about 80 percent of the time within 14 days and about 90 percent of the time within 35 days. These abortifacients are about 70 percent effective for heifers 100 to 150 days pregnant and not very effective for those over 150 days of gestation.
