[QUOTE="hillsdown, post: 651366, member: 5106"] Thank you SL2, and that totally clarifies things and is probably why their are so many "feed lot" pregnancies ....Prostaglandin alone is not good enough you need to give it in conjunction with dexamathesone (or a similar drug) as you do not know how far bred your heifers are they could have conceived at 4 months hence they would be 3-4 months bred if you work them at 8 months old ,or they could have conceived last week. Also it is not 100% effective so it realistically should be done twice... under 3 months bred prostaglandin 3-6 months bred prostaglandin and dex 6 and above dex alone I have Gelbvieh who are known to mature at around 4 months so when we vaccinate the heifers in the fall each heifer gets estrumate (prostaglandin) and dex..So far I have ad good luck with that and the girls come into heat shortly after, however if If I do end up with a yearling bred I will change my protocol and give shots again if I do not see a heat within 4-6 weeks.. BTW,,I do this for all heifers, Pb and commercial, whether I sell them after weening or keep them for replacements.. Hope this helps :wave: ... [/QUOTE]
