[QUOTE="edrsimms, post: 675504, member: 10970"] This could be an array of different things: 1. AI Protocol - what Synchronization method are you using? CIDR inserted 55 days post-calving. I believe that CIDR's are the best way to go, but with a little different way. When you insert the CIDR, you should also give them a 2cc shot of Cystorellin to clear any cystic cows prior to breeding. Pull CIDR Day 7 and for moderate framed cows 5 cc of Lutalyse and larger frame cows 6 cc of Lut. This will make a difference. 2. Check your heifers prior to breeding for any malformed reproductive organs- this will save time and money. 3. Pre- breeding health--- 30 days post calving you should worm your cows and give them a MLV like Titanium 5, which will increase conception rates. Never use a Pour-on during AI. 4. Time of year---- Conception rates are higher during the cooler months (fall calvers) than in late Spring (Spring calvers) 5. Nutrition is a big one.... when you are AI'ing cows 55+ days post-calving they are entering their peak milk production phase where their nutritional requirements are the highest all year-- if you drop the ball 30 days prior you won't have good conception rates. 6. Poor semen handling, which includes thawing, protecting the thawed straw from sunlight, etc. 7. Your AI tech may be punk in his/her skill. 8. Becoming too dependent upon heat patches 9. Not following the breeding rules--- ex: standing heat at 6 am --- breed 6 pm. It is better to breed a little later than to breed early. 10. Some cows just wont cycle when you want them to LOL, some may be in standing heat at Noon or at 11 pm- so you might as well forget your private life until breeding season is over. I would say all these things are important, but Health and Nutrition are usually the biggest factors that cause failure in AI, if everything else is done correctly. You will know of your failure by day 17 to 21..................... [/QUOTE]
