the artificial insemination with frozen-thawed semen in ewes
artificial insemination of the sheep is an advantageous management practice aimed at the genetic improvement at farm level and a program of genetic selection.Furthermore artificial insemination has the potential for a significant impact on the sheep breeding industry.The main role of artificial insemination in sheep production is to increase the rate of genetic improvement and artificial insemination also contributes to achieve other goals, allowing extensive use of the best available rams, therefore increasing selection pressure and the rate of response to selection.With artificial insemination, superior rams can be identified more easily through progeny testing.
