żubroń
Żubroń (; ) is a hybrid of domestic cattle and wisent. The wisent ( in Polish) is the European bison; hence, the żubroń is analogous to the American cattalo. 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 , various scientists considered żubroń a possible replacement for domestic . Żubroń turned out to be more durable and less susceptible t ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovid Hybrid
A bovid hybrid is the Hybrid (biology), hybrid offspring of members of two different species of the bovid family. There are 143 extant species of bovid, and the widespread domestication of several species has led to an interest in hybridisation for the purpose of encouraging traits useful to humans, and to preserve declining populations. Bovid hybrids may occur naturally through undirected interbreeding, traditional pastoral practices, or may be the result of modern interventions, sometimes bringing together species from different parts of the world. ''Bos'' hybrids The following are examples of hybrids including species or sub-species in the ''Bos'' genus. Hybrids between bison and domestic cattle The American bison (''Bison bison'') and European bison (''Bison bonasus'') have been hybridized with domestic cattle (''Bos taurus''). European bison The wisent, or European bison, was originally crossed with cattle in an attempt to reinvigorate the declining wisent popula ...

Białowieża National Park
Białowieża National Park () is a national park in Podlaskie Voivodeship, in Eastern Poland adjacent to the border with Belarus. The total area of the park is . It is located southeast of Białystok (Poland). It is known for the protection of the best preserved part of the Białowieża Forest, Europe's last temperate primaeval forest fragment that once allegedly stretched across the European Plain. It is home to the world's largest population of European bison (), the continent's heaviest land animals. The border between the two countries runs through the forest, the Belovezhskaya Pushcha National Park is adjacent on the Belarus side of the border. There is a border crossing for hikers and cyclists within the forest. According to one study, the park brings in tourist revenues of about 72 million zloty per year. The characteristic feature of the park is its biological diversity. Białowieża National Park is the only Polish natural property designated by UNESCO as a World ...

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.

Beefalo
Beefalo constitutes 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. However, genomic analysis has found that the vast majority of Beefalo, even those considered pedigree by the breed association, have no detectable bison ancestry, with no sampled Beefalo having higher than 18% bison ancestry, with most Beefalo consisting of a mixture of taurine cattle and zebu cattle ancestry. History and genomics Accidental crosses were noticed as long ago as 1749 in the Southern states of North America, during British c ...

Infertility
In biology, infertility is the inability of a male and female organism to Sexual reproduction, reproduce. It is usually not the natural state of a healthy organism that has reached sexual maturity, so children who have not undergone puberty, which is the body's start of fertility, reproductive capacity, are excluded. It is also a normal state in women after menopause. In humans, ''infertility'' is defined as the inability to become pregnant after at least one year of unprotected and regular sexual intercourse involving a male and female partner. There are many causes of infertility, including some that Assisted reproductive technology, medical intervention can treat. Estimates from 1997 suggest that worldwide about five percent of all heterosexual couples have an unresolved problem with infertility. Many more couples, however, experience involuntary childlessness for at least one year, with estimates ranging from 12% to 28%. Male infertility is responsible for 20–30% of infert ...

Parturition
Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species, the offspring is precocial and can move around almost immediately after birth but in others, it is altricial and completely dependent on parenting. In marsupials, the fetus is born at a very immature stage after a short gestation and develops further in its mother's womb pouch. It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are ovoviviparous, with the eggs being hatched inside the mother's body, and others are viviparous, with the embryo developing inside their body, as in the case of mammals. Human childbirth Humans usually produce a single offspri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesarean Section
Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the Surgery, surgical procedure by which one or more babies are Childbirth, delivered through an incision in the mother's abdomen. It is often performed because vaginal delivery would put the mother or child at risk (of paralysis or even death). Reasons for the operation include, but are not limited to, obstructed labor, twin pregnancy, pre-eclampsia, high blood pressure in the mother, breech birth, shoulder presentation, and problems with the placenta or umbilical cord. A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section. A trial of Vaginal birth after previous C-section, vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. A C-section typically takes 45 minutes to an hour. It may be done with a spinal block, where the woman is awake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
