Abstract

Five, non-related, female and male progeny groups of rams were qualified in their body composition and milk production characteristics. Body composition characteristics (fat tissue, muscle tissue and water dense substances) were examined on 38 rams-to-be in 38-48 live weight with CT. Milk production data were collected from the half-sisters (n=106). According to our judgement the influence of rams can be proven statistically in both production characteristics. As we have found close (in order: r = -0,786 and r = 0,721; P<0,05) connection between daily milk production and the areas of muscle tissue and water dense substances of the carcass measured by CT, we suggest taking the correlation between them into consideration in the selection of milk production. To get a precise prediction equation, further examinations are needed.
