the aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of romanian simmental dairy cattle. for the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...

Repeatability of ultrasound-predicted percentage intramuscular fat was studied using observations from 144 head of cattle. Animals were scanned at an average age of 433-d by a certified technician. Each animal was scanned five times using two Aloka 500V machines. Percent intramuscular fat was then predicted by placing a box at two different positions within an image. Overall standard deviation ...
