80% av alla avblekbara skimmel hästar drabbas av cancer. Tumörerna finns oftast på perianala platser (där saker kommer in eller ut) och svansroten men också på huvudet och vid yttersidan av könsorganet. Resterande 20% av alla avblekbara skimlar skulle förmodligen utveckla cancer senare i livet om de hann med att leva tillräckligt länge. Tumörerna verkar inte vara elakartade men sänker ändå livskvalitén på hästarna. Denna cancerform är mycket ovanlig att andra hästar som inte är skimlar får.
Så vi funderade lite över om det kanske hade ett samband med att avblekbara skimlar föds i en färg och bleks med tiden ner till gråvit (svart hud, vit päls). Enda sättet att testa om så är fallet är: 1 föda upp en skimmel och aldrig låta den träffas av solensljus (men det hade förmodligen klassats som djurplågeri i Sverige, finns dock en helt naken häst i USA som har levt hela sitt liv inomhus dagtid och utomhus nattetid). Eller 2. föda upp en White skimmel. Eller typ en homozygot splash tobiano cremello skimmel. För dubbel splash skapar en häst som är vit på hela undersidan av kroppen, tobianot tar bort mycket färgade områden från ryggen och övriga kroppen och cremellot är nästan vitt som det är. Lägger man skimmel på det så kan den inte skimmla ut jättejätte mycket..
Sen började jag titta lite på pudlarnas genetik, och insåg att det fanns en förekomst av cancer inom rasen. Och att även de har en skimmel gen. Eureka! Tänkte jag. Även fast jag ännu inte vet om cancern är färgbunden, väldigt intressant skulle det vara att veta. Även om det har kommit fram mer motstridiga uppgifter nu... Googlade lite på det för en stund sedan nämligen och fick fram denna sidan. Med exempel utdrag i texten:
"The Scottish terrier, Boston terrier, Airedale terrier, cocker spaniel, boxer, springer spaniel, Irish setter, Irish terrier, chow chow, Chihuahua, and Doberman pinscher are the most common breeds affected by melanomas of the skin and toes. The poodle, dachshund, Scottish terrier and golden retriever are the most common breeds affected by melanomas located in the mouth. Other breeds affected include the giant schnauzer and miniature schnauzer, Golden retriever, and Gordon setter. "
Känns som om jag måste börja forska lite snabbt i de övriga rasernas färger och genförekomst. Det kanske inte ens gäller för Sverige. Men teorin om att solen skulle ha stor inverkan börjar kännas avlägsen. Men det skulle ju egentligen kunna finnas många olika sorters cancer som ger samma/liknande symptom/uppkomst även om det påverkas av olika saker...

Old country breeds of swedish hens
Skånsk blommehöna (scania flower hen / flower hen)
From the southern flatcountry of sweden (scania) comes the biggest of the swedish old country breeds. In the villages Vomb, Tofta and Esarp were farmyard flocks found which today is the foundation of todays breed of flower hens. The breed have got its name from elderly scanians which talked about them as “di gamle blommede” (the old flowering).
The shape of their bodies are round and robust. Feathercolor have got its character from the white feathertips on the not so white background color. The groundcolor can be black, bluishgrey, wild/agouti, orange/brown or light yellow. Like most old breeds the flowerhen have single and sawtoothed comb. Some flowerhens have a tuft on the head. Today are the number of hens 900 and 170 males.
----------------------------------------------
Åsbohöna (pronounced: Oss-bo-hoena)
The foddersupply have been very different between the rich flatcountry (Scania) and the poor not so flat northen scania and southern smaland in the past. This little type of hen was pretty common before in villages in that area. The left over birds was recovered in the villages Esborrarp and Linneröd and they are a modest breed adepted to meagre conditions. The birds have lots of colors ie. wild/agouti, weathen, black, blue etc. Some bireds can be speckled as the flower hen. Feathered legs are rare but occur. Shortlegs and dwarfism occur but its nothing breeders keep on breeding.
----------------------------------------------
Ölandshöna [Öland is one of Swedens biggest islands]
Just 6 birds of this breed were found in a village on Öland, on the same farm as the last and now extinct “Ölandshorse” lived. The flock of birds had been there for a very long time and no other breeds had been added to the flock even if someone tried to cross them with leghorns but failed. The birds had many colors before but the remaining birds had just two colors; Striped gray and beige. But now there is some black and wild coloureds. The legs are featherless and the comb is single. The males have a sturdy comb and long bib.
----------------------------------------------
Gotlandshöna [Gotland is the biggest island to Sweden]
In the 1980 were two persons, without knowing the existence of each other searching in many different directions, back and forth across gotland in a look for the old gotlandish strain of hens. Both found what they were searching for on Fårö (which is a small island on the north side of gotland, home to the famous and now dead Ingemar Bergman).
The body of the birds are rough and robust. Feather colouring are commonly wild or brown shaded. But light yellow, black, blue, white and striped occur. Single combed are most common. 466 birds are left today.
----------------------------------------------
Orusthöna (prounounced: O-rust-hoena)
Sometime during 1910 was a flock of small old country breeds collected on the island, were they still was pretty common. They was sold in 1950 as Orusthöns, but it wasnt until 30 years later when someone really saw the bird as a part of the culture and that the birds have genetic worthyness.
The colour are unregular white and black sprackles, so some feathers might be black with white tip and some white with black tip. Some birds got the wild colour, mostly the males which get a golden coloured neck and saddle. White feathers have occured. Single mid sized comb and legs without feathers, often with grey/black spots on them. 371 birds are left today.
----------------------------------------------
Bohuslän-Dals Svarthöna (swedish black hen)
It have been spoken of a raven black hen breed in the border between Bohuslän (in sweden) and Norway. The birds which is the ground for todays Black hens were bought from two brothers in 1958. Their black hens were from their parents which moved to Sweden from Norway in the turn of the century. The birds are beleved to originate from black hens from Mozambique / Africa. The ability which is characteristic for the birds allow black color to spread, not just on the feathers but also on comb, skin, beak, legs. Even their meat are dark. The males can get wild colours. The birds feathers are most commonly smooth but curly can occur. They have featherless legs with 4 toes. White animals can occur too. Featherless skin (comb etc.) are black to redpurple and singlecombed.
----------------------------------------------
Kindahöna (not sure how it is supposed to be pronounced, in swedish xD but i guess its like Chi-nda-hoena)
Elderly people who knows about the breed from their childhood describe it as “the hen with the black color”, “the weird comb” and “the hairy legs”. They comes from a part of the county Östergötland (named Kindabygden). Around 1950 gave an old man around 80yrs old away his birds to a breeder, these birds are the foundation of the todays birds, which is about 600.
Feather colouring vary, but alot of black, wild (with many colour segment in the neck and saddle). The feather structure is either smooth or curly similar to the feathers on silkies. The comb are mid sized and single. Featherled legs are very common. Four toes are common but five toes occur aswell.
----------------------------------------------
Hedemorahöna
Its the most northen of the saved old country breeds. They have being used as gift for the brides family when she left for moving in with her new family (in the past). The bird which are the ground of the todays bird was recovered in a village named Trollbo in Hedemora county (middle of Sweden). They are blue, black, white, wild, weathen and almost white. They have thick layers of feather and down, perfect for the cold climate, (especially during the winters which in that area gives alot of snow.) The feathers on some are curly, like on a silkie. Legs can be smooth or with mild feathering.
----------------------------------------------
Öländsk dvärghöna (dwarf hen from Öland)
Probably have the dwarfhen from Öland its origin from old dwarf hens which were called backyardhens and which were spread via England. They were often white speckled and the ground of Mille Fleur too. They were presumably transported to Sweden. Dwarfhens are not mentioned before 1800. In former times dwarfhens were called pearlhens.
The body are short and rough with tall attitude. Featherings are threecoloured in different shades of brown, black and white. Legs are often smooth with smal amount of feathers on the legs. Single comb
----------------------------------------------
Gammalsvensk dvärghöna (old swedish dwarf)
1860 came a group of “tame bankivahens” to Sweden on the swedish eastindian company boats. The hens were later named “brown bantam”. The now standardised swedish dwarf originate most likely from them. The most unchanged part of the breed preserves as “gammalsvensk dvärghöna” (old swedish dwarf). The body are short and rough with tall attitude. The colouring are wild.
From the southern flatcountry of sweden (scania) comes the biggest of the swedish old country breeds.
