Pedigree Dairy Breeds : Ayrshire


History


The Ayrshire breed originated in the County of Ayr in Scotland, prior to 1800 and was regarded as an established breed by 1812. During its development, it was referred to first as the Dunlop, then the Cunningham, and finally, the Ayrshire. How the different strains of cattle were crossed to form the breed known as Ayrshire is not exactly known. There is good evidence that several breeds were crossed with native cattle to create the foundation animals of the breed. In Agriculture, Ancient and Modern, published in 1866, Samual Copland describes the native cattle of the region as "diminutive in size, ill-fed, and bad milkers." Prior to 1800 many of the cattle of Ayrshire were black, although by 1775 browns and mottled colours started to appear. 


The improvement of the native stock is thought to of begun around 1750 when it was crossed with other breeds such as the Teeswater cattle and Channel Islands cattle. 

Regardless of the details of origin, the early breeders carefully crossed and selected the various strains of cattle to develop the cow we now know as the Ayrshire. She was well suited for the land and climate in Ayr. The Ayrshire is an efficient grazer; noted for her vigour and efficiency of milk production. Ayrshire's are especially noted for the superior shape and quality of the udder. The composition of the milk made it ideally suited for the production of butter and cheese by the early Scottish dairymen.

Many changes have taken place during the late 1980's and early 1990's which have affected the numbers of Ayrshires (and all other breeds) leading to a decrease. Much of this is due to increased profitability of all dairy cows, which has led to an over-supply of milk to the domestic market. However, careful management has convinced Ayrshire breeders that their chosen breed has served them well, and will continue to do so in the future.

Characteristics


Ayrshires are red and white in colour. The red colour is a reddish-brown mahogany that varies in shade from very light to very dark. On some bulls, the mahogany colour is so dark that it appears almost black in contrast to the white. The colour markings vary from nearly all red to nearly all white. The spots are usually very jagged at the edges and often small and scattered over the entire body of the cow. Usually, the spots are distinct, with a break between the red and the white hair. Some Ayrshires exhibit a speckled pattern of red pigmentation on the skin covered by white hair. Brindle and roan colour patterns were once more common in Ayrshires, but these patterns are rare today. 


For many years, the Ayrshire horns were a hallmark of the breed. These horns often reached a foot or more in length, they gracefully curved out and then up and slightly back. When polished for the show ring, the Ayrshire horns were a spectacular sight. Horns are not very practical, and today almost all Ayrshires are dehorned as calves. 

Ayrshires are medium-sized cattle and weigh approximately over 1200 pounds at maturity. They are strong, rugged cattle that adapt to all management systems including group handling on dairy farms with free stalls and milking parlors. Ayrshires excel in udder conformation and are not subject to excessive foot and leg problems. 

Few other breeds can match the ability of the Ayrshire to rustle and forage for themselves under adverse feeding or climatic conditions. The ruggedness of the terrain and the unfavourable climatic conditions of their native land led to the selection for those points of hardiness that adapt them to less than ideal conditions. These traits make Ayrshires outstanding commercial dairy cattle. 

Other traits that make Ayrshires attractive to the commercial dairyman include the vigor of Ayrshire calves. They are strong and easy to raise. Ayrshires do no possess the yellow tallow characteristic that would reduce carcass value, so Ayrshire bull calves can be profitably raised as steers. 

The Ayrshire is a moderate butterfat breed. Top producing Ayrshires regularly exceed 20,000 pounds of milk in their lactations. The current world record for Ayrshire is held by Lette Farms Betty's Ida. In 305 days, on twice-a-day milking, she produced 37,170 pounds of milk and 1592 pounds of fat. The Ayrshire Breeders' Association does not officially recognize records in excess of 305 days, but one Ayrshire has produced over 41,000 pounds of milk and 1800 pounds of butterfat in 365 days.

They are known for low somatic cell counts, ability to convert grass into milk efficiently, and hardiness. The breeds strong points are the now desired traits of easy calving and longevity, Ayrshires are also free of genetic disease. 


Ayrshire milk is referred to as "the ideal drinking milk". Their milk is not excessively rich, not lacking adequate fat, and it possesses quantities of desirable non-fat solids such as protein. 

In South Africa, a chain of large upscale stores selling only high quality products had their cliental taste different kinds of dairy milk (Ayrshire, Holstein, and Jersey). Over 70% preferred the taste of Ayrshire milk over all the other milk. As well, the high fat, protein and kappa casein in Ayrshire milk is a more desirable milk for conversion into yogurt, cheese and ice cream because the particles of fat are slightly smaller and better distributed throughout the milk. The actual average of all Ayrshires on Official DHIR test is over 12,000 pounds of milk with a 3.9% test. 

Ayrshires respond to good management and feeding practices and individual Ayrshire herds average as high as 17,000 pounds of milk and 700 pounds of butterfat. These days it is not rare to see an Ayrshire cow producing over 10, 000 kg of milk per lactation or 80, 000 kg or more in a lifetime.

Distribution


Ayrshires remain popular in many countries such as Russia, North America, Britain, Australia, New Zealand, Africa and parts of Europe and South America. 

Pedigree Dairy Breeds : Dutch Belted


History

The Dutch Belted (Lakenvelder) breed traces directly to the original belted cattle which were described in Switzerland and Austria. The breed was then established in the Netherlands in the 17th century. From the records obtainable, it seems they were bred by the nobility who conceived the idea of breeding animals of all kinds to a particular colour, mainly with a band of white in the center and both ends black. 

The Dutch were very protective of their belted cattle and would generally not part with them. They were highly prized for their milking and fattening abilities. The breed began to flourish in Holland around 1750. (This historical account is found in Professor Raymond Becker's book, Dairy Cattle Breeds: Origin and Development.) 

The American Livestock Breeds Conservancy now lists Dutch Belted as on the critically rare breeds of livestock in the North America, with fewer than 200 registered cattle in the country.

In 1976, after two and a half decades of cross breeding the original Lakenvelders, the remaining cattle of those herds were only 2% well-marked. Since reintroduction of pure bloodlines via semen from the U.S. in 1990, the national Lakenvelder herd is 57% well-marked. 

Dutch Belted have other unique characteristics which make them desirable in crossbreeding programs. Of course, due to the rarity of the pure Dutch Belted crossbreeding can only be recommended by use of Dutch Belted males or semen on common cows, not crossbreeding Dutch Belted females to males of other breeds. Such crossing has been to some extent responsible for the decline in numbers of pure Dutch Belted.

Characteristics

The name Lakenvelder or Lakenfield cattle derives from the word “laken” meaning a sheet or cloth, referring to the white band passing around the body. In some countries animals with this marking are known as “sheeted” cattle. This belt or sheet is of pure white hair extending from the shoulders to the hip bones and should encircle the body completely. The cattle are otherwise black (or occasionally red). In their original form they were horned and primarily a dairy breed – comparing favourably with the Holstein in milk yield. Cows weigh from 900-1500 pounds with bulls bulls weighing 1350-2000 pounds. Their milk tests 3.5 to 5.5 per cent butter fat making it an ideal drinking milk. Dutch Belted are small-boned, making them very easy calving. They have unusual longevity and fertility, high meat yield and friendly dispositions.

  • The breed retains excellent grazing ability and forage efficiency.
  • Optimum calving interval is an important trait for seasonal dairy production.
  • Many cows produce over 20,000 pounds of milk, primarily on forage.
  • Longevity reduces replacement costs, and there are many teenage cows still in production.
  • Moderate frame size results in high dairy beef yield.
  • Heifers breed early and produce a calf every year.
  • Conception rate far exceeds the average 2.7 services required for Holsteins.
  • An average birth weight of 70 pounds assures calving ease and less postpartum stress.
The Dutch Belted offers remarkable genetic consistency resulting from centuries of pure breeding and selection. Dutch Belted bulls are prepotent, and their offspring are highly predictable and uniform. Dutch Belteds can impart significant hybrid vigor when crossed with other breeds. These crossbreds have found great favor in grass-based dairy production. Due to the rarity of the breed, crossbreeding can be recommended only if using Dutch Belted semen on dairy cows of other breeds. Pure Dutch Belted cows must only be bred to pure Dutch Belted bulls.

Distribution

The Dutch Belted although still quite rare can be found in the Netherlands, the USA, Canada, Mexico and there are a small number in New Zealand.
