Hi, I need some advice. I have been feeding Manna pro goat mineral to my goats since ive had them which has been over a year. But it is only sold in a 8lb bag. This doesnt last that long. Well the feed mill the next town over sells Kent brand and Hubbard Feeds brand. The kent brand only has 1,000 ppms of copper that seems kinda low to me. But I looked up the other kind and here is what it has in it. Calcium (CA) min 14.6% Calcium (CA) man 17.5% Phosphorus (P) min 7.0% Salt (NAC1) min 20.0% Salt (NAC1) max 24.0% Copper (CU) min 1,500 ppm Copper (CU) man 1,800 ppm Selenium (SE) min 26.0ppm Vitamin A min 200,000 lu/lb Vitamnin D min 40,000lu/lb Vitamin E min 400 lu/lb Does this look good to any of you. Do any of you use this kind of goat minerals. Also some of my goats are pregnant changing their minerals wont hurt them will it? I think their website did say it had added zinc in it and something else cant remember. Also when changing minerals do you have to do it like feed slowly. I know alot of questions and im sorry. But really need some help with this. Cause the minerals im buying now im paying almost ten a bag for 8lbs. and with this other kind it would be 15 for 25lb. Thanks in advance for all the help.
