If there is a
thread on this already, just beam me to it. I searched but did not find.
I am at a loss how to assess mineral levels in my 4
dairy goats.
Here is my situation. I use rotational grazing with my 4 does. The pasture is not all the way developed yet, but progress is being made. I've only had goats for less than three years. I understand that they have specific mineral needs.
Deborah Niemann's Raising Goats Naturally has been very helpful, in fact I am going to write a 9 or 10 acorn review soon as I organize myself into it.
Pat Coleby's Natural Goat Care is also an excellent reference, but the mineral depletion she describes in her goat keeping in Australia is not necessarily equal to the mineral status of my soil. The
local ag extension guy says we have"young" soil, not yet depleted, but how do I know?
Steve Solomon's The intelligent Gardener describes a system for assessment and remineralization of the soil. His system is based on tests and targets that differ from the generic recommendations of agribusiness and most extension agents. He gives particular consideration to alkaline soils (which I have). I had the tests he recommended, and I do have less copper than optimum, but usually copper comes as copper sulfate, and I have too much sulfur, so it is a puzzle.
Further, though most of the valley considers there to be a selenium deficiency in the region's soils, I do not have the standard soil for the region, and my
irrigation water from the Gunnison River while most of the valley uses the Colorado, runs through a region that has major selenium, so it is hard for me to believe there is a selenium deficiency at my place.
Niemann and Coleby and many others describe the effects of copper deficiency in goats, it disrupts their reproductive cycle and their coats (important for various reasons), among other things.
I dosed copper sulfate with dolomite and do see some improvement, but I would like those girls to bloom! I looked at getting COWP, but the fine print says it's not very bioavailable. Elsewhere I read that selenium levels affects the animal's ability to absorb copper, so a goat can have a copper deficiency when there is plenty of copper if the selenium is wrong. Cobalt is also a variable.
I don't know how to assess MY goats needs for minerals.
Currently, the two doelings I kept from this spring's kids have lush coats, lots of undercoat and the ends of their tails are great plumes. Their heats were easy to detect. Of the remaining two, the three year old has minor "fish tail", a shining coat with lots of underfur. Her heat was easy to detect. She only gives about a third as much
milk as my 4th goat.
In my fourth goat, who is older (~ 6 or 7) who gives almost two gallons a day at peak, and is still giving 3 quarts a day, her coat is rougher, she has the fish tail, and she did not come in to heat that I could detect (got blood test confirmation of pregnancy in the other three).
I treated them all for internal and external parasites with
DE, and really would like to get them all the minerals they need.
My concerns also include the knowledge that in humans at least, and therefore possibly other mammals, an oversupply of iron cannot be detected by blood tests as the body stores the iron somewhere, and it is possible to have iron toxicity, which developed despite blood levels being normal. Niemannn has described instances where she requested liver tissue be tested on her goats that died, in order to confirm her suspicions and further her knowledge of goat health and goat demise. I don't want to wait for a goat to die, and liver biopsy seems pretty drastic and likely very expensive.
So, there you have all my confusion factors. I don't know how to assess the individual goats' needs for minerals, and don't want to just dose them all on everything because toxicities can be as bad or worse than deficiencies. There is added expense there as well as endangering the goats through toxicities and just generally messing with the microflora of their miraculous rumens.
So how do all of you work the puzzle of what minerals when for your goats?
Thanks so much!
