Annual Report of the AETA Statistics Committee For Calendar Year 2006

1 Annual Report of the AETA Statistics Committee For Calendar Year 2006 Embryo production is still on the rise in both dairy and beef cattle! Take a look and compare your ETB s data to others in your region. Fewer ETBs Reporting Data for 2006 (Down 8 from 2005) # ETBs 2004 # ETBs 2005 # ETBs 2006 NorthEast SouthEast NorthCentral SouthCentral NorthWest SouthWest s There were 113 certified ETBs reporting in 2006 as compared to 115 in Most of the reduction in reporting was non-certified companies, which dropped from 19 in 2005 to 13 in Diversification is inching into the ET industry. 63 ETBs reported being full time, and nearly as many, 61, claim to professionally devote only part time to ET. Data also indicate only 1.01 professional ETB, while the average ETB employs

2 2.1 support staff. There could be some confusion about what defines support staff. For example, for those ETBs housing donors (69 in all), do they count outside employees who feed cattle as support staff, or do they count lab support staff only? Also, what about clerical or secretarial staff? Should they be included as support staff? Our committee will try to define support staff more precisely before next year s questionnaire is sent to the membership.

It was up over 2600 collections and 10,000 viable embryos produced.

However, it should be noted that only a fraction of the equine data are included in this data set, both for 2005 and The number of equine embryos collected for 2006 very likely exceeds 10,000, and probably 15,000. The AETA does not have many members in the equine industry; therefore, the data collected are a poor representation of the industry s actual numbers. The same could be said for sheep and goats.

It will likely be a future generation that benefits from our data, but we should be good stewards and collect them diligently. Please keep accurate records whenever possible on a daily basis regarding the number of non-usable ova. Embryo Transfer Conception s and Data Combined Preg. Glyerol Preg. DT Preg Over 90% of these data for conception rates are estimated. Since the mid 1980s, when ET practitioners started no longer being paid by the pregnancy, actual pregnancy data are difficult to acquire. Conclusion The statistical committee would again like to thank you, the members, for getting your stats in on time. For those who didn t, and haven t yet, it really slows down the process of gathering and assimilating the data. Each that has to be written and each phone call made in behalf of these delinquent files is an added burden to the committee, the president, and to the AETA office and it costs money. The benefits are obvious. ET practitioners and ETBs can evaluate their volume relative to their geographical counterparts as well as a nation wide comparison. Those of us in and outside the industry can see the direction of the industry from year-to-year. These numbers are very beneficial to potential buyers of US genetics. There were some very good comments on the questionnaire this year. One suggested that we ask for data on donors bred with sex sorted sm. The committee will consider some clarifications and possible new questions, but there will likely be few changes in the questionnaire for 2007 data. Brad Stroud, DVM Chairman AETA Stats Committee
