Acorns do have feed value ... but they can also be a danger to livestock.Every deer hunter knows that deer love acorns. In the old days pigs were left to run in the woods where they survived on mast, including acorns. Acorns were a staple in the diets of some American Indians American Indians: see Americas, antiquity and prehistory of the; Natives, Middle American; Natives, North American; Natives, South American. . Yet, every once in awhile we hear of someone losing animals to "acorn poisoning." Here are several items relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc that. COUNTRYSIDE: Someone requested information on acorn nutrition. I became interested in this several years ago after reading about them in Tree Crops. I had always read that oak leaves and acorns were poisonous to goats, but David Mackenzie's Goat Husbandry claims that it is only green acorns and leaves. Once dry, they are nutritious and my goats gobbled them like kids eat candy. They even preferred them over their daily grain ration. It's not practical to grind the acorns as they would spoil quickly. The goats had no problem with them whole anyway. I found I could gather about 60 pounds an hour under a "good" tree. I stored them in feed sacks but found that if they were brought into the cellar where it was warm, a small worm hatched inside them. After that I kept them in the barn. Here is the information given on page 200 of Goat Husbandry regarding acorn composition: 41.2 lbs. starch equivalent/100 lbs. 2.7 lbs. digestible digestible having the quality of being able to be digested. digestible energy the proportion of the potential energy in a feed which is in fact digested. digestible protein see digestible protein. protein/100 lbs. 50 percent moisture Mineral state is low Palatability is acceptable (This I find understated!) The following sample feed program set up by my agricultural extension Agricultural extension was once known as the application of scientific research and new knowledge to agricultural practices through farmer education. The field of extension now encompasses a wider range of communication and learning activities organised for rural people by agent using Mackenzie's tables provides the 1.36 pounds starch equivalent and .13 pound digestible protein required for daily maintenance of a 140 pound goat.
