| George Washington – Father 
      of our Country – but father of the American Mule as well? Yes, George 
      Washington is often given credit as the first mule breeder in the 
      Americas, although a few sources will cite otherwise. It is a fact that 
      General George was given two fine Spanish Jacks, one dubbed “Royal Gift”. 
      This animal, so eagerly awaited for the production of mules, had not, 
      apparently, been trained to serve mares. Modern breeders with jennet jacks 
      or mule jacks will understand quite well that Royal Gift’s mares were 
      covered the first year by an Arabian horse stallion who was more than 
      willing to take his place. 
       The 
      following season, Royal Gift was helped to his duty with the use of a few 
      jennets, and the American Mule was on its way. This jack was much in 
      demand, and eventually toured the southern states, siring mule foals all 
      the way. But of course, one jack could not sire all the mules in the 
      country, and no one breed of donkey is used today in the production of 
      mules. Today’s Mammoth Jackstock is a blend of a number of different 
      breeds, some with strikingly different characteristics. A breed is defined as a specific type of equine with similar 
      characteristics. If two members of the same breed are mated, the result is 
      another is another purebred with the same body type, coloration, etc. 
      There are no longer any real populations of true donkey breeds in the 
      United States. The registries are bound by size, not breed type. A few 
      small populations of endangered or “rebred” breeds survive worldwide, but 
      their blood can be found blended in the donkeys classified as Miniature, 
      Standard, Large Standard, and Mammoth in the U.S.
 The distinct body types and characteristics of some of the now-lost breeds 
      can be easily seen in the Mammoth jackstock of today. The fine-boned, 
      black Majorcan type, or the heavy-boned, dappled Andalusian can be seen 
      side by side in the show ring. Depending on the preference of the owner, 
      both of these types of jackstock can sire excellent mules for a number of 
      uses.
 
 All known former breeds of donkeys have made a contribution to the Mammoth 
      at one time or another. Although the Mammoth is still determined by size, 
      breeding for characteristic and type can be achieved by breeding like 
      animals to attain a certain look. Many breeders are no longer 
      familiar with the types used to produce the gentle giant, but occasionally 
      an advertisement will state “Catalonian Jack” or “Andalusian Jack”. These 
      should be carefully examined for pedigree, for with a solid recorded 
      background, these animals are merely of Catalonian or Andalusian type, and 
      should not claim that bloodline. In a noted example, the long 
      shaggy coat of the Poitou is so dominant a trait that a 1/10th Poitou 
      animal may have as heavy a coat as a purebred, although lacking in bone.
 
 By the beginning of the 20th century, Mammoth jack breeders had combined 
      the breeds available to produce a type of jack specifically for the 
      production of mules. Today, the types are being used once again for 
      different purposes, instead of continuing the blend into the perfect 
      specimen. The tall, slender black jack may be used for saddle mules, and 
      the heavy-boned, drafty dappled red roan used for draft mules.
 
 To be listed as Mammoth Jackstock, the jack should stand 56” and taller, 
      the jennet 54” and taller. The tallest known Mammoth stood 17 hands, 
      although this animal only lived to the age of three. Color is not an 
      issue, although black or sorrel (or dappled red roan) jacks are favored in 
      draft mule production. The gray-dun (slate) color prevalent in the smaller 
      donkey types is not favored, although it can be seen. Even large spotted 
      Mammoths are being used to produce spotted saddle mules. No matter the 
      height or color, the Mammoth breeding jack should be a superb specimen, 
      with good proportion and sufficient bone to be in balance.
 
 A frequent fault found in Mammoths is long back, with small hips and weak 
      loins. The hip of the donkey is already smaller in proportion to that of a 
      horse, and this fault seems to go with other body types in some cases. 
      Jacks used for jackstock production should be the absolute best specimens 
      available. Those used exclusively for mule production may be forgiven some 
      flaws, but conformation can affect performance, especially in the working 
      of the “power train,” the hind end.
 
 There are five main breeds that were incorporated into the development of 
      the Mammoth jack of today: the Andalusian, Catalonian, Majorcan, Maltese, 
      and Poitou. The gray-dun and spotted influence most likely came from 
      Standard breeding, since the original breeds did not include these colors.
 
       The 
      Andalusian This donkey was the drafty, heavy-boned, dappled animal. Most of the 
      original animals imported into the U.S. (even up into the 1900’s) were 
      dappled gray-roan (sometimes called blue roan) or red roan. The average 
      height of the Andalusian was 14.2-15hh. Many of the heavy sorrel jacks 
      used in draft mule breeding resemble the purebred Andalusian quite 
      closely. The head should be in proportion, but this is the breed most 
      likely to have a thick jaw, and Roman-type nose. The bone was heavy 
      especially through the leg, and breeders wishing for a heavier type of 
      jack should look to this type to add substance in both jackstock and 
      mules. Most jacks today that exhibit the Andalusian characteristics are 
      sorrel or dappled red roan, with little or no visible cross being 
      preferred.
   
       The 
      Catalonian This was one of the most popular breeds for use in creating American 
      jackstock. The purebred Catalonian was always black, no grays or roans 
      were ever allowed. The haircoat was fine, short and glossy. The Catalonian 
      was finer-boned and used exclusively in Spain for the production of mules. 
      This breed became the one of choice when creating the Mammoth, even though 
      the average height was only 15 hands and the bone was finer and lighter 
      than that of other jackstock breeds. Today a very tiny population of 
      Spanish Catalonians still exists in Spain, and another small Mexican 
      Catalonian population as well.
 MajorcanThe Majorcan jack, also of Spain, was often crossed with the smaller 
      Catalonian to produce a superb breeding jack. Black in color, although not 
      quite with the fine-textured haircoat of the Catalonian, these jacks 
      contributed size and bone to the Mammoth. They were often described as 
      “sluggish” in disposition, but there is also the possibility that they 
      were some of the largest jackstock in existence. The demand for these huge 
      animals quickly depleted the supply and there are no known populations of 
      this breed today.
 MalteseFrom the Island of Malta, early jackstock breeders purchased every 
      animal with any hope of breeding quality, including those whom it was 
      hoped would grow taller. Most did not, and the animals as a breed were 
      less than 14 hands tall. They were often a clean black, and their manner 
      described as having extreme vigor and vitality.
 
       Poitou Probably the most striking of the jackstock breeds, the Poitou 
      survives today as an endangered breed. It is felt by some jackstock 
      historians that the Poitou was used far less in the production of today’s 
      Mammoth than it should have been. The Poitou is found in France (although 
      evidence supports they were bred from Spanish stock many centuries ago), 
      and was used almost exclusively for the production of mules. Bred to an 
      incredibly heavy draft horse breed called the Mulassier, mules believed to 
      be some of the finest work and draft animals in the world were produced.
 
 The Poitou is noted for the heavy bone, and memorably, for the long 
      tangled coat, forming dreadlocks to the ground. The coat color is 
      exclusively black or dark brown (termed bai-brun by the French) and should 
      never bear a cross or stripe. This horrific coat, matted with filth and 
      years’ worth of shed hair caught year after year, was prized (!) and said 
      to be a symbol of purity in the breed.
 
 A few Poitous were exported for breeding, and early engravings of these 
      noted animals show them with shaggy, yet neat, coats. It is suggested that 
      these jacks lacked the matted coat and were penalized in France. Those 
      that were used in jackstock production contributed bone to the Mammoth, 
      not only in leg, but in the length of the back and distinctive shape to 
      the face.
 
 Cost of transporting jacks to the United States, as well as the high cost 
      of the animals themselves, may have contributed to the fact that these 
      jacks did not play as large a role as they could have in Mammoth 
      production. If greater numbers had been available, or transportation 
      easier, the Poitou might have further shaped American Mammoths. There are 
      less than 200 purebred Poitous left in the world, and the Poitou Mule has 
      become almost extinct.
 
       Today’s 
      Mammoth Although today’s Mammoth is a blend of these breeds, and certainly of 
      even Standard donkeys of unknown origin (the spotted and dominant gray-dun 
      influence), he is a far cry from the first mule sire, which was probably a 
      Syrian Wild Ass. Mules in Biblical times were vastly different from the 
      wide range of types and sizes enjoyed by the longear fancier of today.
 
 The modern mule breeder can take a jack of any color from black to sorrel 
      to dappled to spotted and breed to quality mares of any imaginable breed, 
      and produce a mule suited for any type of work or use. Draft mule breeders 
      may prefer the matched blonde sorrel in their mule, but the saddle mule 
      owner can selectively try for spotted, dun, white, dapple gray, bay, 
      palomino, or even colors and patterns unique to that marvelous mule. 
      Choose jackstock wisely, regardless of color, and the mules of tomorrow 
      can be assured of a place in the public eye as animals more worthy of 
      praise than of “old wives’ tales”. With support and care, the mule and 
      the mule jack are outgrowing old stereotypes and taking their place 
      alongside developed horse breeds as the Equine of Choice!
