Relationship of fertility to milk yield in Swedish cattle.

Journal of dairy science - 1 Jan 1991

Oltenacu P A, Frick A, Lindhé B

Abstract excerpt

Data consisted of 48,830 and 21,136 records of Swedish Red and White and Swedish Black and White cattle. Fertility in virgin heifers and in first lactation cows was measured by first service pregnancy rate and number of services per pregnancy. Production trait considered was FCM produced in first 100 d of lactation. The heritabilities for fertility traits in virgin heifers and first lactation cows were about .05...
