I have one Grumpy daughter that I like very much. Also an Alstar daughter who is very nice plus she gave me a gorgeous Yogibear daughter this past June (Friday the 13th). I forget who my third adult female is sired by without looking at her registration.
A number of companies carry Guernsey semen. I tend to work with select sires because there's a rep close to me and they carry more (but not a lot) bulls than I've seen elsewhere. I was lucky that I was able to buy a variety of small amts of semen from the dairyman who I bought my girls from.
I've not had Guernseys long but have also found them hearty. They all did well in last Winter's extreme cold and don't seem bothered by the heat. They pasture with my beef cows and do well though they know the beef cows are the bosses. I recently visited an Amish dairyman who has about 30-40% Guernseys in his commercial dairy with Holsteins and crosses. He loves them and uses a lot of Guernsey semen on his Holsteins. His Guernseys look great with great udders. The guy said he obviously doesn't show but likes cows that look like they could. My vet said that herd is the highest producing herd that his wife tests.
Last year when my first Guernsey was about to freshen I talked to my vet about possible problems. He just said, "she's a Guernsey, they almost never have problems freshening".
That being said, my Yogibear heifer calf was huge and needed a little traction at birth. I was close to calling the vet. A few days later, her mom had surgery for a displaced fourth stomach, which apparently is not that rare in dairy cows after delivery. She had that big surgery standing up with a lot of local and petting. She healed great and kept on milking.
