  • Estimation of stayability traits in black-and-white cows in Slovenia = Ocena prežitvene[!] sposobnosti pri kravah črnobele pasme v Sloveniji
    Pogačar, Janez, 1941-1999 ...
    Average stayability rate at age 48 months, which is 75 %, at age 60 months, which is 61 %, and at age 72 months, which is 47 %, was estimated for 4742 Black-and-White cows off spring of 35 bulls that ... had at least 30 daughters. For estimation of stayability, values should be corrected to milk production. Heritability rates for stayability traits were estimated as follows: 0.05 for stayability at age 48 months, 0.08 for stayability at age 60 months and 0.09 for stayability at 72 months. The genetic variability for stayability traits is satisfactory so that selection to stayability traits is reasonable and necessary from the point of view of economy.
