We don't expect our bucks to look anything but rangy this time of year. Winn used up one whole service memo book, while GE only bred 56 does this year

Pi our new young buck bred 17 does before he was 9 months old and is now breeding 2 more next month. Yep rangy. GE has always had the ability to keep on more weight, he also doesn't perfume himself like Winn does either, so his hair stays fluffy and blonde
Mine get about 3 pounds of alfalfa pellets each, minerals, all the grass hay they want, 10 acres of woods to eat through and 3 pounds of grain each once a day (it's a goat grain with ammonium chloride in it). Once out of rut because we are appraising them in april, PI about 150 pounds will stay on 3 pounds, but the big boys, over 200 will more up on grain pellets) But do keep them wormed, I don't fecal the boys they are much more likely to have adult blood sucking worms way before you see alot of eggs this time of year...no worm mom worth her salt is going to lay a bunch of eggs this time of year that would be pooped out onto the frozen ground!!! So you normaly see much less eggs in poop this time of year. But do check your goats for anemia...got a FAMACHA chart? Really you don't need one Doc, just look at one, it will give you the idea quickly.
Once the oat hay comes in, in Feburary and the bucks are out of rut, they will gain weight...appraisal here is in April, so they had better gain some weight! Vicki
