KOJAK - HIGH FERTILITY NON SHEARING MATERNAL

The BreedersBEST Kojak is a new generation composite Non Shearing Breed developed to meet the future needs of the Australian lamb industry.

Early sexual maturity, high fertility, growth and shedding are paramount selection criteria. The importance of all these factors are critical in our Kojak breeding programs. With the infusion of the Finn Gene into the Kojak we are now enjoying a much higher reproductive rate out of their progeny.

Two seasons ago we introduced Ultra white genetics to enhance muscle characteristics. Three leading Ultrawhite sires were sourced and utilised in an embryo transfer program over our high fertility Kojak ewes.

-SELECTED FOR MATERNAL CHARACTERISTICS

-HIGH FERTILITY (EXPECTED LAMBING 145%)

-LARGER FRAME- LEANER CARCASE

-RAPID GROWTH RATE, MATING LAMBS FROM 7 MONTHS OF AGE

-EASILY CONTAINED

-IMPROVED CONFORMATION (ESPECIALLY FEET)

-LOW FAECAL WORM EGG COUNT (FWEC) SELECTION


KOJAK CLIENT TESTIMONIAL

Hamish Thorn at Kojonup mated 1800 Kojak ewe lambs in early February and achieved an 88% conception rate. The ewe lambs averaged 50 -55kg liveweight and were estimated to carry 30% multiples and mark 100% lambs - not bad for ewes that are only 12 - 14 months of age.

John South, Knack Pty Ltd at Darkan first purchased Kojak rams in 2010. He immediately observed an increase in the lambing percentage and growth rates from their then Dorper flock. John said "the BreedersBEST genetics have provided ongoing improvements to all our flock, with increasing lamb scanning percentages, weaning percentages and growth rates". "As prime lamb producers, we consider these genetics will ultimately provide us our goal which is to grow the majority of our lambs to be abattoir ready on seasonal green grass" John said. "In addition, the experiences the Heggaton's have gained from many years of practical work whilst commercially farming a large-scale prime lamb operation, provides us with a great deal of guidance and assistance".

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, leaner 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 cross Kojaks should not require shearing.
  • Improved structural confirmation - especially feet.
  • 2% higher carcass yields in comparison trials
  • 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.
