The OLIBS ewe is a two breed composite of Polled Dorset and Rideau Arcott. The lineage of both ewes and rams can be traced to the original OLIBS research flock from the University of Guelph. The Replicating Breeder's Association is working to ensure the genetic progress of the OLIBS flock for the benefit of commercial buyers. There are several advantages for commercial producers to purchase OLIBS replacement ewes. The genetics and health status are the same among the Replicating Breeder's flock so large orders can easily be supplied. Through single sire mating, extensive flock records and sire referencing, the Replicating Breeder's achieve ongoing genetic advancement to the benefit of commercial buyers. Purchasing OLIBS replacements ewes every year, allows the commercial producer to concentrate on providing uniform quality lambs for the meat market. High index, terminal sires can be purchased and utilized for their full productive life without risk of in-breeding. Replacement ewe lambs are born throughout the year. High-health ewes relate to lower flock depreciation costs and should wean more pounds of lamb per ewe as well as more lambs per ewe. The health status also provides commercial producers with opportunities to participate in future Quality Assurance schemes. The OLIBS Replicating Breeder's have been participants in the Ontario Sheep Health Program (OSHP) since its inception. They have the level one health certificate and an "A" status on the Maedi Visna project. In 2004, the Replicators began a monitoring program for Scrapie. All flock sires were genotyped for Scrapie resistance. All ewes that die on the Steele farm are tested for scrapie and all test results to date have been negative. The OLIBS Flock lambs in January, April/May and September on the "3 times in 2 years" accelerated lambing system over a 34 day period. Lambs are weaned at 50 days of age. All animals are individually identified and recorded. All females, surplus to flock replacement needs, are sold as replacement ewes to commercial producers. |

All
ewes are single sire mated and recorded on the Ontario Sheep Flock Improvement
Program. Ewe lambs are bred at 7 months of age to lamb at 1 year old.
Replacement ewes are selected for maternal traits under intensive management
conditions, i.e. fecundity and 50 day lamb weights. The genetic worth
of the OLIBS ewes is established by SFIP records and EPD's. The
OLIBS Flock is also recorded on the Ewe Byte computer program. Ewe Byte
is a comprehensive sheep management system designed for health, lamb
production and pedigree tracking. |

| It provides extensive action lists, reports, including graphical presentations. Also provided are in depth life history reports for ewes and rams, including lifetime productivity and health. Ewebyte farm records can be easily downloaded into the Ontario Sheep Flock Improvement Program for calculation of adjusted weights and multi-trait indexes as well as EPD's. | |||||||||||||||
