KOJAK - HIGH FERTILITY SHEDDING MATERNAL

The BreedersBEST Kojak is a composite Non Shearing Breed developed over the last 25 years to meet the future needs of the Australian lamb industry.

BreedersBEST Genetics Kojak ewes this year achieved 155.8% fecundity.

High fertility, rapid growth, early sexual maturity, and shedding are paramount selection criteria. The importance of all these factors are critical in our Kojak breeding programs. The early infusion of both the Finn(GDF9 fertility gene) and East Friesian has provided a huge lift in reproductive rate, milking ability and subsequent growth rates.

Several seasons ago an infusion of Ultra white genetics enhanced muscle characteristics. Three leading Ultrawhite sires were sourced and utilised in an embryo transfer program over our high fertility Kojak ewes.

Right: 15 month old Kojak ewes with twin lambs at foot. These ewes will completely shed by summer, and will undergo embryo transfer flushing this season.

WHEN COMPARED TO EXISTING NON SHEARING BREEDS KOJAKS ARE . .

  • Easily contained with 6/7 line ring lock with NO requirement for a lower barb wire or electric fence.
  • Increased fertility (averaging 20 - 30% increased lambing percentages over existing non shearing breeds).
  • Produce a larger carcass - Kojaks grow out to heavy weight lambs without excessive fat coverage.
  • Kojaks have rapid growth rates - due to their larger frame, Kojak lambs have increased growth rates by a minimum10%.
  • Better shedding when grading up from Merino or other wool breeds. Second to third cross Kojaks should not require shearing.
  • Improved structural confirmation - especially feet.
  • 2% higher carcass yields in comparison trials
  • High worm resistance resulting in reduced worm burdens and less drenching requirement.
  • As the majority of progeny are produced via embryo transfer, only elite genetics are used for breeding. For a Kojak ewe to enter the breeding flock she must conceive and rear twin lambs by 13 - 15 months of age.
