> You can only mature the calves if you can spare the milk, and you get a lot more calories from just drinking the milk. Perhaps in the short term. But after 10 weeks calves exclusively eat grass. And after a year on grass the riginal 10 week dairy calorie investment is dwarfed by the beef fat calories produced. I think it comes down to land costs and labour costs. Most Irish land is only suitable for livestock. Rough grassland is cheap. And hand milking is labor intensive. The Dexter cattle breed originated in Ireland, is suitable for both dairy and beef, and is tough enough for harsh conditions. Scaling up on beef male cattle makes sense if the grassland is available.
