Yakalo
The yakalo is a cross of the yak (''Bos grunniens'') and the American bison (''Bison bison'', known as a buffalo in North America). It was produced by hybridisation experiments in the 1920s, when crosses were made between yak bulls and both pure bison cows and bison-cattle hybrid cows. As with many other inter-specific crosses, only female hybrids were found to be fertile ( Haldane's rule). Few of the hybrids survived, and the experiments were discontinued in 1928.Deakin, A, Muir, G W, Smith, A G (1935). "Hybridization of domestic cattle, bison and yak. Report of Wainwright experiment".

Beefalo
Beefalo constitute a hybrid offspring of domestic cattle (''Bos taurus''), usually a male in managed breeding programs, and the American bison (''Bison bison''), usually a female in managed breeding programs. The breed was created to combine the characteristics of both animals for beef production. Beefalo are primarily cattle in genetics and appearance, with the breed association defining a full Beefalo as one with three-eighths (37.5%) bison genetics, while animals with higher percentages of bison genetics are called "bison hybrids". History Accidental crosses were noticed as long ago as 1749 in the Southern states of North America, during British colonization. Cattle and bison were first intentionally crossbred during the mid- 19th century. One of the first efforts to cross-breed bison and domestic cattle was in 1815 by Mr. Robert Wickliffe of Lexington, Kentucky. Mr. Robert Wickliffe's experiments continued for up to 30 years. Another early deliberate attempt to cross-br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Żubroń
Żubroń (; pl, żubroń ) is a hybrid of domestic cattle and wisent. The wisent (''żubr'' in Polish) is the European bison; hence, the żubroń is analogous to the American beefalo. The name żubroń was officially chosen from hundreds of proposals sent to the Polish weekly magazine ''Przekrój'' during a contest organised in 1969. History The żubroń was first created by Leopold Walicki in 1847, although the hybrid may also have appeared at an earlier time. After World War I, various scientists considered żubroń a possible replacement for domestic cattle. Żubroń turned out to be more durable and less susceptible to disease. In addition, the animal could be bred on marginal grazing land with no farm infrastructure and with minimal husbandry in huge state agricultural farms (SAFs). From 1958, the work on żubroń herds was continued by the Polish Academy of Sciences in various laboratories, most notably in Białowieża and Młodzikowo. During the first 16 years of experimen ...

American Bison
The American bison (''Bison bison'') is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovid Hybrids
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday, ...
