A successful ovulation synchronization program with timed AI would allow farmers to add new, higher-value genetics into their herd more efficiently than with estrus synchronization and traditional AI. Estrus synchronization reduces the amount of time required for checking estrus (heat) before AI.

Third Wheel: The Insemination Of Elizabeth

Estrus synchronization combined with artificial insemination (AI) is used regularly in cattle and has been useful for breeding management. Differences between years is not surprising given differences in weather and other variables that can change from year to year, though the exact reason for the much lower rates in Year 3 is not known. CIDR removed; intramuscular injection of 3 cc Lutalyse and 2. Semen storage may not be needed. Pregnancy rate for does in NC Synch 72 group (11 of 21): 52%. The times between drug treatments were changed to better fit the reproductive responses of goats. However, using timed AI (TAI) so that all animals are bred the same day without heat checking is even more efficient, saving time, money, and labor. The NC Synch method was used with TAI and was developed based on Ov-Synch protocols used in cattle. Whitley, N. C., C. Farin, W. Third wheel: the insemination of elizabeth tchoungui. Knox, L. Townsend, J. R. Horton, K. Moulton and S. Nusz. Because exposure to buck pheromones can shift ovulation timing in does that have not been in prior contact with bucks (known as the buck effect), it is important to be sure that does are managed carefully when considering the NC Synch TAI protocol. These benefits allow for lower-cost, more efficient AI technology adoption. Pregnancy rates were higher for animals treated with the CIDR method (50%) than the NC Synch method (10.

Some advantages to timed AI include: - No heat checking is used. Does were housed together and were kept from sight, sound, and smell of all bucks until day 15 when all were allowed fence-line contact to an intact buck. Half of the animals followed the Heat Check method described below: |. At NCSU, Boer does that had kidded at least once before were assigned to either traditional estrus synchronization with AI following heat checking (Heat Check) using the AM-PM rule (if in estrus AM, breed PM, and vice versa) or the ovulation synchronization method with timed artificial insemination (NC Synch). All breeding can occur on a single day that is selected by the farmer and/or AI technician, allowing for purchase and use of semen without long-term storage. The key for effective timed AI is the s ynchronization of not just estrus but also of ovulation (egg release). Third wheel: the insemination of elizabeth arden. Frozen semen from a commercial company (Superior Semen Works, Milton, NH) was used for all AI, and motility of samples was confirmed for each straw. At about 50 and 85 days after artificial insemination, animals were checked for pregnancy status using transabdominal ultrasonography. Heat Check (18-24 hr. The same technicians did the inseminations (with equal numbers for each technician in each treatment group). Half of the does underwent the NC Synch method developed at NCSU as described above, and the other half underwent a CIDR method as follows: CIDR ®* Method. These technologies would also be useful for goat farmers interested in using AI to increase the genetic merit of offspring. A follow-up study was conducted at NCSU using 87 Boer and Boer-crossbred does that were divided into four treatment groups: Heat Check method described above, CIDR Method described above, NC Synch with TAI at 48 hours after the second Lutalyse injection (NC Synch 48) and NC Synch method with TAI at 72 hours after second Lutalyse injection (NC Synch 72, the NC Synch protocol used previously).

After the artificial insemination breeding period, all animals were returned to the flock and managed through the standard operating procedures for the farm. Blood samples were collected 31 days after insemination to determine pregnancy status (BioPRYN® BioTracking, LLC). Comparison of two ovulation synchronization methods for timed artificial insemination in goats. Data on kidding, including number of females kidding to AI breeding date, number of kids born, number of kids born alive, and twinning rate, were recorded. NC Synch 72: 21 does synchronized and bred by TAI, 11 does pregnant. All does were exposed to bucks via fence-line contact prior to the start of any treatments. At the Upper Mountain Research Station, NCSU, NCA&TSU, and station staff conducted a demonstration and applied-research project using 38 Boer-crossbred does.

Breed (AI) by AM-PM rule.

This research was conducted for three years (2007 to 2010). All Years Combined: Pregnancy rate for does in Heat Check group (35 of 66): 53%. Intramuscular injection 3 cc Lutalyse. The results are shown below: Heat Check: 22 does synchronized, 18 bred, 12 does pregnant. The low pregnancy rates associated with the NC Synch method in the Upper Mountain Research Station study may have resulted from an early ovulation in this group of does that had not been exposed to bucks prior to the start of the experiment. All animals were bred by timed AI on day 17. If an AI technician is being hired, a single trip can be scheduled. In recent research and demonstration projects at North Carolina State University (NCSU) and North Carolina A&T State University (NCA&TSU), ovulation synchronization methods for timed AI were compared. Not labeled for use in goats in the United States. NC Synch: A protocol for ovulation synchronization and timed artificial insemination in goats. Intramuscular injection 1cc Cystorelin and AI. These studies demonstrate the importance of making sure that AI occurs at the right time relative to the synchronized ovulation in TAI protocols.
