Cattle originally meant movable personal property, especially livestock of any kind, as opposed to real property (the land, which also included wild or small free-roaming animals such as chickens—they were sold as part of the land). [2] The word is a variant of chattel (a unit of personal property) and closely related to capital in the ...
A freemartin or free-martin (sometimes martin heifer) is an infertile cow with masculinized behavior and non-functioning ovaries. [1] Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin . [ 2 ]
Artificial reproduction was not achieved because of the difficulties in hatching or feeding some farmed species such as eel and yellowtail farming. [24] A suspected reason associated with the late realization of success in selective breeding programs in aquaculture was the education of the concerned people – researchers, advisory personnel ...

Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.
Furthermore, direct evidence for meiotic recombination, indicative of mating and sexual reproduction, was also found in G. intestinalis. [11] Other protists for which evidence of mating and sexual reproduction has recently been described are parasitic protozoa of the genus Leishmania, [12] Trichomonas vaginalis, [13] and acanthamoeba.

The size of the bovine genome is 2.7 Gb (2.7 billion base pairs). [4] It contains approximately 35,092 [4] genes of which 14,000 are common to all mammalian species. Bovines share 80 percent of their genes with humans; cows are less similar to humans than rodents (humans and rodents belong to the clade of Supraprimates) and dogs (humans and dogs belong to the clade of Boreoeutheria).
