Coat Colour Lakeland Terrier A Discussion of Coat Colour Genetics in the Lakeland Terrier Chapter 8— Liver By Ron Punter Liver/Chocolate/Brown - the bb gene A recessive Red homozygous for Liver gene will have a liver nose. The first Gallaher cigarette card featuring a Lakeland I saw looked Liver and Tan but have since seen much darker ones so probably that's just a function of the printing process but in real life Liver is a very distinct colour. Liver has long been in the standard but it omits to say Liver and Tan. Even though it’s not spelt out it’s clearly implied and will be legitimately produced from the Lakeland Terrier gene pool and nobody could sensibly argue that Liver and Tan is not an acceptable colour. The American KC standard does precisely list it: “A saddle may be blue, black, liver, or varying shades of grizzle” The American standard is generally much better written as regards colour although they do have an “alternative” registration code for “Brindle” which would be untypical in a Lakeland Terrier. These pups are already trained to do a “down stay” at 7 weeks old. Two rather different looking Livers. An interesting observation from the principle breeder of Liver and Tan Lakelands in the UK: “You know how the Black and Tans have a sort of grey in their coats when they are about ready to strip, especially the grizzle ones. The Livers do not get that only gold.” Page 2 As the bb changes all eumelanin not just in the coat : Noses will always be Liver in a Liver and Tan also the eyes will be lighter. The first standards only mentioned a black nose. From about the 1960’s The Lakeland Terrier Club included a note about Liver noses in Liver dogs . When the KC revised standards in about 1980 we got them to include Liver noses in Liver dogs. I well remember the debate at the LTS, I was chairman at the time. Most people even though they might not understand the genetics are fair minded and it was decided that if the standard allows Liver and it’s impossible not to have a liver nose then the standard must allow it. Someone queered if a red nose in a Red dog should be allowed but that did not find favour on the grounds that it is possible to have a black nose in a Red dog even if some people were finding it difficult to breed one at that time! There have been at least three mutations over time that have produced changed structure in the Tyrosinase Related Protein 1. These are often labelled bc, bd and bs though they all have the same effect -produce eumelanin granules which are smaller and rounder in shape which appear not as black but a lighter colour -basically brown. These three can be genetically tested for at the time of writing, more could follow. It would first need to be established which type is present in Lakelands. The Liver coat colour in Lakelands gives an object lesson in how a recessive gene can be carried forward for many generations before coming out . Years ago I had a dog at stud that carried it and he was line breed to Ch Tarnbreck Comet. Other breeders who had produced Livers in the north of England had Comet in the pedigrees as the common denominator. Page 3 People who have had a Liver often would like to have another and a farmer with a Liver bitch specifically wanted to mate her to a dog, not too closely related, that carried Liver. It was a 50:50 chance and could not offer any guarantee but happily he did get his wish and bred a Liver puppy to run with its mother. Don’t know of many Livers in the north of England nowadays. It’s mostly Rachel Chamness (Kelda) in Devon that is keeping the colour going. On geographical location one might think that Liver came into Kelda line from Joe Blackburn’s Culverdale breeding. Joe showed a couple of livers and had a stud dog that Biddy Morris thought a carrier. It was Joe who wrote the note that the Let us in! LTC put on the standard The Liver colouration is not so obvious about the nose colour. In in an adult as it is in a whelp. fact it would seem that the Kelda liver strain too comes from Comet. Chocolate Drop of Ashgate, born 1986 is the last Liver and Tan that I can remember in the show ring, he was not breed by Miss Morris but was used by her and has brought the Liver colour into the current Kelda pedigrees he is of Northern breeding from two kennels that used Comet fairly extensively. The other dog carrying the Liver gene into modern Kelda is Kelda Henry of the Tors –traced him to Ch Tarnbreck Comet on both sides of his sires pedigree in fairly short order! Pedigrees of Liver and Tan’s in the USA indicates that a grandson of Comet, Ch Scartop Crazy Horse might have taken the gene across the Atlantic. Page 4 A stud dog has much more chance to influence a breed than ever a bitch can, in the case of passing on the gene for Liver coat colour its not a problem and those with a preference for the colour have cause to be grateful to Ch Tarnbreck Comet. However its a clear illustration why it’s a problem in breeds with inherited diseases and how a problem from way back comes to the fore again when decedents of an undetected carrier are mated together. Thankfully genetic tests will soon make it easy to breed out health problems and limiting a particular sires influence in a breed will no longer be an issue. Genetic testing should soon be sweeping away much of the criticism of pure bred dogs. Liver and Tan youngster trimmed out for show. The colour is not very obvious in this photograph and might never be as obvious as it is in a whelp. A lot depends on just how the light falls. Page 5 .

  • Chronic Liver Disease and Complications 0615-01
    Chronic Liver Disease and Complications www.weilab.com 0615-01 Nonalcoholic fatty liver disease (NAFLD) is a clinicopathological term that encompasses a disease spectrum ranging from triglycerides and other fat accumulations in hepatocytes (hepatic steatosis) to steatohepatitis with inflammation, fibrosis, and cirrhosis. It is believed that NAFLD is the cause of many chronic conditions including type II diabetes, cardiovascular and athroskelerosis which is the leading cause of death in the US, brain and neurologic problem such as stroke and Parkinson’s. NAFLD is the biggest health concern now affecting 20% (32 millions) of Americans. Recent studies support a “two-hit” model to explain the progression of NAFLD. The “first hit” constitutes the deposition of triglycerides in the cytoplasm of the hepatocyte. The disease does not progress unless additional cellular events occur (the “second hit”) that promote inflammation, cell death, and fibrosis, which are the histologic hallmarks of nonalcoholic steatohepatitis (NASH). 1) The First Hit: Hepatic Steatosis or Fatty Liver Hepatic Steatosis, or fatty liver is characterized by excess fat especially triglycerides built up in liver cells. The liver is one of the major organs to synthesize triglycerides as the body's energy supply and cholesterol which function for bile, Vitamin D, hormones production and cell membrane support. Its synthesis is under feedback regulation through activation and deactivation of the sterol receptor element binding protein-1c (SREBP-1c). The abnormally increased activation of this protein causes over production of cellular lipids resulting in accumulation of excessive fat in the liver. Research has shown that malnutrition, especially a deficiency of choline and a high fructose diet with a high degree of sweetness such as high fructose corn syrup found in our processed food upregulate SREBP-1c activation and is believed to be the major cause of fatty liver.

  • Sporting Group Study Guide Naturally Active and Alert, Sporting Dogs Make Likeable, Well-Rounded Companions
    Sporting Group Study Guide Naturally active and alert, Sporting dogs make likeable, well-rounded companions. Remarkable for their instincts in water and woods, many of these breeds actively continue to participate in hunting and other field activities. Potential owners of Sporting dogs need to realize that most require regular, invigorating exercise. The breeds of the AKC Sporting Group were all developed to assist hunters of feathered game. These “sporting dogs” (also referred to as gundogs or bird dogs) are subdivided by function—that is, how they hunt. They are spaniels, pointers, setters, retrievers, and the European utility breeds. Of these, spaniels are generally considered the oldest. Early authorities divided the spaniels not by breed but by type: either water spaniels or land spaniels. The land spaniels came to be subdivided by size. The larger types were the “springing spaniel” and the “field spaniel,” and the smaller, which specialized on flushing woodcock, was known as a “cocking spaniel.” ~~How many breeds are in this group? 31~~ 1. American Water Spaniel a. Country of origin: USA (lake country of the upper Midwest) b. Original purpose: retrieve from skiff or canoes and work ground c. Other Names: N/A d. Very Brief History: European immigrants who settled near the great lakes depended on the region’s plentiful waterfowl for sustenance. The Irish Water Spaniel, the Curly-Coated Retriever, and the now extinct English Water Spaniel have been mentioned in histories as possible component breeds. e. Coat color/type: solid liver, brown or dark chocolate. A little white on toes and chest is permissible.

  • Fatty Liver Diet Guidelines
    Fatty Liver Diet Guidelines What is Non-Alcoholic Fatty Liver Disease (NAFLD)? NAFLD is the buildup of fat in the liver in people who drink little or no alcohol. NAFLD can lead to NASH (Non- Alcoholic Steatohepatitis) where fat deposits can cause inflammation and damage to the liver. NASH can progress to cirrhosis (end-stage liver disease). Treatment for NAFLD • Weight loss o Weight loss is the most important change you can make to reduce fat in the liver o A 500 calorie deficit/day is recommended or a total weight loss of 7-10% of your body weight o A healthy rate of weight loss is 1-2 pounds/week • Change your eating habits o Avoid sugar and limit starchy foods (bread, pasta, rice, potatoes) o Reduce your intake of saturated and trans fats o Avoid high fructose corn syrup containing foods and beverages o Avoid alcohol o Increase your dietary fiber intake • Exercise more o Moderate aerobic exercise for at least 20-30 minutes/day (i.e. brisk walking or stationary bike) o Resistance or strength training at least 2-3 days/week Diet Basics: • Eat 3-4 times daily. Do not go more than 3-4 hours without eating. • Consume whole foods: meat, vegetables, fruits, nuts, seeds, legumes, and whole grains. • Avoid sugar-sweetened beverages, added sugars, processed meats, refined grains, hydrogenated oils, and other highly processed foods. • Never eat carbohydrate foods alone. • Include a balance of healthy fat, protein, and carbohydrate each time you eat. © 7/2019 MNGI Digestive Health Healthy Eating for NAFLD A healthy meal includes a balance of protein, healthy fat, and complex carbohydrate every time you eat.

This meeting has been kindly funded by the Government of the Federal Republic of Germany, through the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB). UNEP/CMS/AWA/ Inf.1 The African wild ass (English translation by Robin Stocks (2016) of p. 164-180 from the German book ‘Wildesel’ [Wild asses], Thorbecke, Stuttgart, 221 pp., 1999, by Gertrud and Helmut Denzau, proofread by the authors) Between the middle ages and early modern times, wild asses and zebras were sometimes confused with each other (Oken 1838). Before they were first scientifically described, there were numerous references to the existence of African wild asses, such as in the report by Cailliaud (1826), which lists onager together with other wild animals as desert dwellers in northeastern Sudan. In 1851, an Abyssinian wild ass was brought alive from Massawa to Paris that Geoffroy (1855) designated Asinus ferus or Equus asinus ferus. This animal was variously classified in later years and ultimately, including by Groves (1966), deemed on the basis of its skull dimensions to be a domestic donkey hybrid. Even before a trapper or hunter could get hold of a truly wild specimen, taxonomists had already begun assigning names (see p.
