Mimeo DH-105
Revised September, 1967
AVAILABLE AI SIRES, SEPTEMBER 1967
The sires listed herein were reported as active in AI on January 1 ,1967 or later, and having sufficient daughters with herdmates to meet minimum qualifications for summary. Bulls were considered as active if alive, or if semen is available in regular service if the bull is dead.
Records of production of daughters of these sires are shown in comparison with their non-paternal herdmates calving in the same season of the year. Production data shown for daughters with herdmates includes records from states other than Indiana.
For convenience in use of this mimeo, sires listed are by breeds and in numerical order or registration number. The number of states in which daughters are now located (No. St.) is shown in the second column followed by the stud number in which the bull is located; see key following list of sires.

Percent of daughters sold for beef or died in their first lactation (Inc. %) is shown next. This column is blank if the first lactations were not available on 50% or more of the daughters. The number of daughters (No. Daus.) with herdmates included in the sire summary is listed next.

Average 305-2X-M.E. production of these AI daughters tested is shown. Next appears the production of herdmates with their 305-2X-M.E. production.

Repeatability of sire summary indicates the repeatability of this summary to future sire summaries. It should be used as a "confidence factor" or measure of the relationship between this proof and the true breeding merit of the bull.

The predicted difference is an indicated change in level of production of a sire's daughters from the average of herdmates and variances from the breed average under wide use and under all types of feeding and management conditions. This difference is indicated in part by the number of states reporting daughters on test.

Thus, a sire with a large number of daughters in many herds and states with a large increase in both milk and butterfat production would be expected to provide satisfactory genetic improvement for a breeder.

Lists of sires by registration numbers can be checked quickly through use of sire lists Applied by technicians or your own registration papers or breeding slips.

Additional information on these and other AI service sires is available in the DHIA  Summary List. This list is available at your County Extension Office. This mimeo supplements other issues of DH-105 and should be filed with your other issues of DH-105.
