Relationship between production and days open at different levels of herd production.

Journal of dairy science - 1 Jun 1994

Marti C F, Funk D A

Abstract excerpt

Five production variables and days open were analyzed using 611,680 records from 348,243 cows in 5694 herds enrolled in the Wisconsin DHI program. Production variables included 305-d milk production and several production measures adjusted for combinations of mature equivalent, fat and protein content, and effects of days open. Herds were divided into four groups by herd production. Heritability estimates for...
