Let's talk calcium and pregnancy.
Just a heads up to everyone running rabbits right now. The alfalfa crop coming out of Texas (fall 2025) has been testing low in both mineral density and protein efficiency. That matters more than people think. If that crop made it into pellet production, your bag may not actually be delivering what the tag says on paper. And we’re starting to see it. What I’m seeing — and what others are reporting — lines up: • more brittle bones • increased fractures • does struggling to kindle • more straining in labor • poor milk production • DOA kits or underdeveloped kits • late-term losses or does dumping litters in the third week Because of this, and because I’ve now seen it in more than one doe, I’ve started supplementing calcium in the water during the last week of pregnancy through the first 5 weeks of nursing. Mix and dosage are at the end. This is now being added into Class 5 of the nutrition course, but I’m putting it here because this is one of those moments where waiting costs litters. What Calcium Is Actually Doing in a Rabbit Calcium in rabbits gets reduced to “sludge” conversations way too often, and that misses the entire point. Calcium is not a side mineral. It is a structural, metabolic, and reproductive driver. Rabbits are built to absorb calcium efficiently and use it continuously. Their entire system assumes it will be available. When it’s not, things don’t degrade slowly. They fail across multiple systems. Growth — Building the Frame Calcium is what builds the rabbit. It drives: • bone formation • tooth development (which never stops in rabbits) • structural growth When calcium is inadequate, you don’t just get “slower growth.” You get: • weaker frames • poor bone density • dental problems • long-term structural compromise You are not raising a smaller rabbit. You are raising a weaker one. Bone — Maintenance, Not Just Growth Bone in rabbits is constantly being remodeled. Calcium is moving in and out of storage all the time to support: • muscle contraction
