[The cattle breeding program of the Republic of Cuba]. / Zum Rinderzuchtprogramm der Republik Kuba.

ABSTRACT

The Cuban cattle breeding programme has remained unchanged over more than 20 years and aims at the genetic transformation of the indigenous population by means of crossbreeding within a high-performance cattle stock. Focus is on the breeds Holstein X Zebu in order to produce the crosses "Holstein Tropical" (7/8H 1/8Z), "Mambi" (3/4H 1/4Z), and "Siboney" (5/8H 3/8Z). Besides these, other new breeds are envisaged for milk and meat production. Representative parameters of the production and reproduction of the new genotypes are being reported and discussed.
