A method of estimating heritability of the functional symmetry of the udder, without using classification of groups of related animals


, : A method of estimating heritability of the functional symmetry of the udder, without using classification of groups of related animals. Lucrari Stintifice, Institutul de Cercetari pentru Cresterea Taurinelor (6): 59-66

For 370 Romanian Simmental, 41 Romanian Brown and 60 Friesian cows, the h2 of the difference between milk production of the front and the rear halves of the udder was 0.61, 0.77 and 0.42 resp. in the 1st lactation, 0.64, 0.46 and 0.33 in the 2nd, and 0.46, 0.56 and 0.46 in the 3rd.

The ability to discriminate between ruptured and unruptured cerebral aneurysms on a morphological basis may be useful in clinical risk stratification. The objective was to evaluate the importance of inflow-angle (IA), the angle separating parent v...

Studies were performed to determine if the sustained elevation in [Ca2+]c noted previously in glomerulosa cells in response to Ang II resulted from the presence of HEPES in the experimental medium. At confluence, primary cultures of bovine glomeru...
