Silver Appleyard

Silver Appleyard is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Silver Appleyard rather than just read about it. In short: The Silver Appleyard is a British breed of duck. It was bred in the first half of the twentieth century by Reginald Appleyard, with the aim of creating a dual-purpose breed that would provide both a good quantity of meat and plenty of eggs.

Key takeaways

  • Silver Appleyard belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Silver Appleyard to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Silver Appleyard from memory before moving on to harder problems.

Reference excerpt

The Silver Appleyard is a British breed of duck. It was bred in the first half of the twentieth century by Reginald Appleyard, with the aim of creating a dual-purpose breed that would provide both a good quantity of meat and plenty of eggs. Like the majority of breeds of domestic duck, it derives from the wild species Anas platyrhynchos.

History The Silver Appleyard was bred in the 1930s at Priory Waterfowl Farm near Ixworth, in Suffolk, by Reginald Appleyard, an expert poultry breeder who also created the Ixworth breed of chicken. His aim in creating the breed is described in a leaflet he put out after the end of the Second World War: to create white-skinned duck with a wide, deep breast, which would also be beautiful to look at and would lay abundant white eggs. By the time the pamphlet was issued, his birds had won prizes at the Dairy Show in London and at Bethnal Green. In 1947 a pair of Silver Appleyards was painted by the animal painter Ernest George Wippell. Appleyard worked on the development and stabilisation of the breed until his death in 1964, but never produced a standard. The appearance of his original stock is unknown; when the Silver Appleyard standard was drawn up in 1982, it was based on Wippell's painting. Some birds were taken to the United States in the 1960s. The breed was added to the Standard of Perfection of the American Poultry Association in 2000. It is listed as "threatened" by the Livestock Conservancy. There are two small-sized versions of the Silver Appleyard. A Silver Appleyard Bantam was bred by Reginald Appleyard in the 1940s by cross-breeding Khaki Campbell ducks and Call drakes; it thus did not have the same genetic origin as the large bird. The Silver Appleyard Miniature was created in the 1980s by Tom Bartlett of Folly Farm and was recognised as a separate breed in 1997; it is about a third of the size of the large bird, and so is not small enough to be termed a bantam. Appleyard's bantam version was renamed, and is now the Silver Bantam.

Characteristics The Silver Appleyard is a compact duck of medium length, with a broad and rounded body carried at some 20° to the horizontal. The bill is broad and of medium length; it is yellow with a dark bean, somewhat more greenish in the drake than in the duck. The legs are yellow, the eyes hazel. The plumage is closely similar to that of the Rouen Clair, but with pigmentation of the head and body reduced by the action of the restricted mallard gene. Body weights are in the range 3.2 to 3.6 kg for ducks, 3.6 to 4.1 kg for drakes.

Use The Silver Appleyard was created as a dual-purpose breed, reared both for meat and for eggs. Birds for the table may reach a weight of 3 kg at nine weeks; ducks are good layers of white eggs, and may lay some 200–270 per year. The birds are also kept for showing.

Worked examples

Example 1 — a first encounter with Silver Appleyard

Start with the simplest possible case. Write down what Silver Appleyard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Silver Appleyard before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Silver Appleyard ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Silver Appleyard

In research
Silver Appleyard appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Silver Appleyard in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Silver Appleyard is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal breeds on the RBST Watchlist, Duck breeds, Duck breeds originating in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life
Look for Silver Appleyard outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
