[QUOTE="Bovine breeder, post: 1558662, member: 29557"] This is a very interesting topic. I’ve been wrestling with the milk EPD myself recently anyway. I think there was some discussion in another thread about it. The EPD definition reads “pounds of calf weaned attributed to milk production” that sounds good but how do we really know? I feel like most people just evaluate how well the calf grows and how big the udder is when reporting data. But many dairy experts tell me udder size does not mean much when it comes to true milk production. Which brings up the discussion about protein and fat content in the milk vs. fluid volume. But again, without actually measuring it, how do you know? I realize calf performance is a roundabout way of doing so, but it just isn’t as scientific as I’d like it to be. Lol. To circle back to the question, in the genomic data I’ve received on my cows, I’ve found milk has a huge variability. I used Hickok who is Average for milk, and had daughters with raw scores between 26 and 77. I would say milk is like any other trait in that the more generations you stack it into the cattle with a consistent approach, the more consistent the results will be. I would probably expect the fire and ice matings to land all over the board. [/QUOTE]
