[QUOTE="farmer on a bike, post: 7374127, member: 295"] We have housed our heifers this year for the first time for quite a few years. Previously we sync'd. We used a PRID sync and put on estrotect stickers. We served anything with rubbed stickers about 50 hours after pulling PRIDs using sexed semen and applied new stickers. On the following day we AI'd the heifers were now rubbed but whose stickers had not gone off the day before with sexed semen and any of the heifers served the day before but rubbed again with beef. in total we served about 85-90% of the heifers and then put bulls in. In the last 2 years doing that we have had 64% and 68% of all the heifers calve to sexed semen. Last year we had almost 100 heifers to make up for TB, unfortunately last year the bulls went off there feet in the wet autumn. Fortunately we realised what was happening so PD'd the whole bunch and kept back the 24 not showing as 28d pregnant and all 24 then came bulling, and I got 22 in calf with 4 weeks of AI. That made me think. So this year the heifers are inside but we do only have 64. We have used cow manager ear tags for spotting bulling but stickers could be an option. We had a pen with a calving gate in it off to one side and pulled out bullers as needed, usually with the help of a second person just to get them in the pen. I then sorted the AI on my own swapping which heifer I needed behind the calving gate. We have not PD'd yet but I served every heifer in 22 days and 45 are currently holding to first service (we have had about 4 long returns) and I have only served 5 heifers in weeks 5-8. So far I have just done 83 services on the 64 heifers in 8 weeks which certainly helps with reducing the work load. The biggest issue is finding the heifers, sometimes they are obvious with sweaty coats, however we are serving twice a day 10-22 hours after start of heat so they are often finished heat so less obvious. Estrotect stickers would help solve that issue of ID in a bigger group but you would probably need to handle them more to replace part worn stickers etc. [/QUOTE]
