Chillin' with the herd
(If anyone reading isn't aware, alfalfa is 16-20:1 calcium : phosphorous, and corn is something like 1:5--high in phosphorous. You can feed fairly high levels of Ca or P, as long as they are balanced with each other at about 1.8-2:1 for goats. If your balance gets too far off, such as 1:1 or 5:1, you'll start seeing symptoms relating to calcium or phosphorous toxicity or deficiency, depending on your details. Now during lactation, the increased need for calcium is relatively higher than the increased need for phosphorous--yes, they need a little extra of that too--so lactating goats can tolerate higher ratios of Ca : P than they normally would. Anyway, just extra credit info for the science nerds out there . )
(And by the way, an imbalance in that ratio is what typically leads to urinary calculi, as well, generally too much phosphorous. Grains are high in phosphorous, most greens like grass and hay are the ideal of about 2:1, and that is why you most commonly see urinary calculi in pet male goats (smaller urethra and getting grain when they do not have an increased demand for production).)
