The same technicians did the inseminations (with equal numbers for each technician in each treatment group). Third wheel: the insemination of elizabeth holmes. After the artificial insemination breeding period, all animals were returned to the flock and managed through the standard operating procedures for the farm. 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.

Intramuscular injection 3 cc Lutalyse. Half of the animals followed the Heat Check method described below: |. At the Upper Mountain Research Station, NCSU, NCA&TSU, and station staff conducted a demonstration and applied-research project using 38 Boer-crossbred does. 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. Based on the research and demonstration work of Dr. Charlotte Farin and William Knox, North Carolina State University, and Dr. Niki Whitley, The Cooperative Extension Program at North Carolina A&T State University. Estrus synchronization reduces the amount of time required for checking estrus (heat) before AI. Pregnancy rates based on ultrasound at 50 and 85 days after breeding. NC Synch 72: 21 does synchronized and bred by TAI, 11 does pregnant. Pregnancy rate for does in NC Synch 72 group (11 of 21): 52%. Whitley, N. C., C. Farin, W. Knox, L. Townsend, J. R. Horton, K. Moulton and S. Nusz. 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. Blood samples were collected 31 days after insemination to determine pregnancy status (BioPRYN® BioTracking, LLC). References (peer-reviewed abstracts): E. C. Bowdridge, W. B. Knox, C. S. Whisnant, and C. Third wheel: the insemination of elizabeth nj. E. Farin. NC Synch: A protocol for ovulation synchronization and timed artificial insemination in goats.
All does were exposed to bucks via fence-line contact prior to the start of any treatments. 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). The times between drug treatments were changed to better fit the reproductive responses of goats. Intramuscular injection 1cc Cystorelin and AI. These technologies would also be useful for goat farmers interested in using AI to increase the genetic merit of offspring. These benefits allow for lower-cost, more efficient AI technology adoption. The key for effective timed AI is the s ynchronization of not just estrus but also of ovulation (egg release). The results are shown below: Heat Check: 22 does synchronized, 18 bred, 12 does pregnant. Third wheel: the insemination of elizabeth j. The remaining does were bred using the NC Synch with TAI method described below: NC Synch with TAI Method. 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.

Heat Check (18-24 hr. Breed (AI) by AM-PM rule. Not labeled for use in goats in the United States. The NC Synch method was used with TAI and was developed based on Ov-Synch protocols used in cattle. Comparison of two ovulation synchronization methods for timed artificial insemination in goats. 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). 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. All Years Combined: Pregnancy rate for does in Heat Check group (35 of 66): 53%. This research was conducted for three years (2007 to 2010). 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. 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. Some advantages to timed AI include: - No heat checking is used. All animals were bred by timed AI on day 17.
