I have been raising Boer Goats as a hobby for 11 years. This year ALL but one of my 2021 doelings look like barrels with legs. They developed the big bellies when weaned. The first couple scared me and I treated for bloat but they are all healthy. FAMACHA is great. They are all sired by the same quality buck (first time used) but since the mommas have been bred before and produced normal looking kids, I am wondering if this is a trait in the sire's bloodline. They are on a large professionally managed pasture and are fed twice a day with 24/7 access to minerals and have received copper bolus. The other older does in the same environment are "normal" looking. Any thoughts?
