The rutabaga when fed raw in excess causes thyroid congestion.
Glucosinolates are present in different ratios in peel and pulp of turnips.
I am not elaborating here on the properties of the individual glucosinolates.
According to a Scottish study stockbeet when stored for 3 months looses about 1/3rd of its nitrate content.
I think the following might be the only extant cultivars:
Barres (available in Poland and the Ukraine)
Brigadier (available in the U.K.)
Eckendorf (yellow and red varieties)
Golden Tankard (a famous English variety)
Long Red (high yield but poor storing capacity)
Vilmorin's Yellow Intermediate
When fed in excess stockbeet causes urinary afflictions especially in rams.
Stockbeet contains adipic acid.
I favour the course white carrot originating in Belgium for livestock feed owing to its lower carotene level; this might be different with lactating animals.
I have done some preliminary research in dietary supplementation with white salsify for swine, this has a lower inulin level than chicory root, excess inulin congests the liver and elevates the blood ammonia level.
Of the former a cooked mash could be made and cultured with lactobacillus species, for infirm swine, though it should be noted that Streptococcus thermophilus toxin will irritate the liver, so I would exclude that bacteria from any cultured mash. Noted is that lactobacillus species will hydrolise inulin.
As solanine according to my research is a thyroid irritant, the level of that compound in pototoes should be addressed when that root is fed to swine.
I'll eventually write something here regarding kale cultivars, Maris Kestrel and Caledonia, respectively developed for small ruminants and cattle.
A blend of seed for self-mown hay.
I am not addressing here the phytochemicals in the plants.
1 kg Danish Roskilde Cocksfoot or Orchard Grass ( Dactylis glomerata )
1.5 kg Aberystwyth S. 143 Cocksfoot ( Dactylis glomerata )
1.5 kg Aberystwyth S. 26 Cocksfoot ( Dactylis glomerata )
1 kg Danish Meadow Fescue ( Festuca pratensis )
500 gr Alta American Tall Fescue ( Festuca elatior )
250 gr Rough Stalked Meadow Grass ( Poa trivialis )
125 gr Smooth Stalked Meadow Grass ( Poa pratensis )
2 kg R.V.P. Italian Ryegrass ( Lolium italicum )
3.5 kg Reveille Tetraploid Perrenial Ryegrass ( Lolium perenne )
500 gr Canadian Climax Timothy ( Phleum pratense )
1 kg Grasslands Huia White Clover ( Trifolium repens )
750 gr Alsike Clover ( Trifolium hybridum )
500 gr Atlaswede Red Clover ( Trifolium pratense perenne )
250 gr Kent Wild White Clover ( Trifolium repens silvetre )
500 gr French Chicory ( Chicorium intybus )
1 kg Burnet ( Poterium sanguisorba )
500 gr Sheeps Parsley ( Petroselinum sativum )
250 gr Ribgrass ( Plantago lancelota )
125 gr Yarrow ( Achillea millefolium )
From the list neither Kent clover nor burnet are cultivated in Denmark, ribgrass and yarrow are considered common weeds.
Large scale cultivation occurs in Denmark of Dactylis glomerata and Poa pratensis for seeds, and also large scale cultivation of Lolium italicum, Lolium perenne, and Trifolium hybridum.
Chicory is grown for seeds in Denmark and also the root is sometimes fed to swine to reduce "boar taint", but as above I consider white salsify might be of interest.
I am not elaborating here on the phytochemical properties of Chicorium intybus, nor of Tragopogon porrifolius, other than the mention of inulin content.
I'll eventually write something here regarding field preparation for pasture raised swine.
There was some interest a few years ago on improvement of chestnut cultivars suited to the Danish climate, I'm not familiar with the congealing of lard of swine fed chestnuts, this doesn't occur when they are fed acorns, the former however in analysis of the Chinese variety (Castanea mollissima) contains β-D-glucopyranoside, a renal irritant.
