Brett’s Blurb (Brett Wilson, Dohne Data Manager)
Sheep Genetics Reports: Episode 4.
The fourth report from Sheep Genetics that needs investigating is the Reproduction Summary.
This report is complete review of reproduction records for your stud in the analysis and is used to review the quality of the reproduction data recorded.
This is normally a one page report with the results in the top half and some explanations in the bottom half. The report is normally displayed in Landscape view; however for this newsletter I have split the report so I can display it easier.

 

The first 5 columns of data are simple counts of the number of lambs, dams and different conception methods in the data for each year of birth.
The next 2 columns show the ewe fertility for each year as a percentage. No Dohne stud should lamb the maiden ewes at Yearling stage so that is always “0.0” The Adult column is what needs to be checked.
The Analysis Flags is Sheep genetics way of representing if the NLB (Number Lambs Born) and NLW (Number Lambs Weaned) data is being included in the reproduction analysis. You want this to be Y:Y (Yes for NLB and Yes for NLW) at the adult stage (we don’t look at Yearling Fertility)

The right hand side of the report has another 13 columns of information.
The Preg Scan records are only used if lambing outcome is unknown. With full pedigree of lambs and inclusion of Dry ewes and Dead lambs Dohne breeders should have a complete listing of lambing outcomes.
Repro Dams is the count of dams in the reproduction analysis.
Ewes Missing is a count of ewes that were present in both the year before and the year after but not in this year. This is used to determine if you are missing Dam records.
The Next 8 columns of data have counts for the different Birth Types followed by counts of Rear Type.
Finally the count of ewes that have been excluded from the reproduction analysis due to a sire failure is listed. If a Sire has a problem we cannot blame the ewe for not getting pregnant so therefore is not included.

Important points of this report
Note this is a high quality dataset but the 2015 drop has an issue.

  1. Notice the Ewe Fertility % at adult stage is 100% for the 2015 drop. It is not really possible to have 100% fertility.
  2. Notice that the 2015 analysis flags for NLW and NLB are No and No. So due to a failure in the data these dam records are not be included. Illustrated by having “0” Repro Dams.
  3. The question becomes what is wrong with the 2015 drop data. The answer is shown by the fact there are Zero Birth Type records of Zero. This means there is not a single dry ewe from the 2015 drop joining, that is not possible. The DAB lambs are included as shown by the 102 lambs with a rear type of Zero.
    • This stud is in the process of going through the mating records and sending me a list of dry ewes for the 2015 drop to fix this problem.
  4. Interesting to note that in 2013 and 2014 there were 20 odd ewes in each year that are listed as missing but were mated the year before and the year after.
  5. Also note that the 2017 drop has 168 adult dam reproduction records excluded because of a sire failure. The stud does not believe there was a sire issue and we are investigating the issue.

One last point I would like to look into is the issue of Rear Type. It has never been a requirement for Dohne Breeders to record Rear Type. We record Full Pedigree and Birth type but the analysis system does not work out Rear Type for us. If Rear Type is not supplied in the data the system automatically issues a rear Type of 0 for any DAB or DRY and a 1 for any live lamb, this is shown in the example for the 2013-2016 drops. The stud in this example has identified the value in reporting rear type and has started supplying that information as shown by the 456 Twin rear type in the 2017 drop data.

Next time I will continue to review the sheep genetics reports, till then happy data collecting.
