THE ISRAELI BREEDING PROGRAM
THE ISRAELI BREEDING PROGRAM
1 .300 elite cows selected based on their genetic evaluations. About ½ of these cows are mated to local elite bulls, and the remainder with elite foreign bulls.
2 .About 60 bulls calves sons of elite cows are purchased by the AI institutes yearly.
THE ISRAELI BREEDING PROGRAM
3 .All first parity cows are inseminated with semen from young bulls. About 100 milk daughters are produced from each sire.
4 .In addition, 20,000 cows are inseminated with semen from high P.I. Bulls.
THE ISRAELI BREEDING PROGRAM
5 .About five elite sires are selected based on first parity daughter evaluation, and are returned to general service.
6 .These five sires are mated to about 1,000 virgin calves to test for dystocia and calf mortality.
THE ISRAELI BREEDING PROGRAM
7 .All other virgin calves are mated to proven sires with favorable evaluation for
dystocia .
8 .All later parity cows are inseminated with semen from proven bulls at a flat rate fixed to cover operational costs of the AI institutes and the ICBA.
