Performance of Polypay, Coopworth, and crossbred ewes: I. Reproduction and lamb production.

Journal of animal science - 1 Jan 1992

Nawaz M, Meyer H H

Abstract excerpt

Six ewe genotypes, generated by mating Coopworth (C), Polypay (P), and Suffolk (S) rams to Polypay and Coopworth-type (Ct) ewes, were exposed to Hampshire rams for spring lambing from 1986 through 1990. Data from 1,092 exposures and 1,044 resultant lambings were used to analyze reproductive trait...
