The Gerudo race is a matriarchal society of warriors that is almost exclusively female, with the only exception being that a male Gerudo is born every 100 years, who then becomes their leader. [ 2 ] [ 3 ] Their tendency to bar interaction with men is due to the belief that it will lead to disaster, with the only male interaction allowed being ...
The horns are longer than in most other breeds and are present in both males and females. Mature bulls weigh from 408.2 to 700 kg (900 to 1,543 lb). Among fighting cattle, there are several "encastes" or subtypes of the breed. Of the so-called "foundational breeds", only the bloodlines of Vistahermosa, Vázquez, Gallardo and Cabrera remain today.
The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed to create polled versions of dairy breeds. [5] In sheep, the allele for horns in both sexes is partially dominant to the allele for being polled in both sexes, and both of these are dominant to that for polling in the female only. [6]
Often, mentions of dams imply cows which will be kept in the herd for repeated breeding (as opposed to heifers or cows to be sold off sooner). A young female before she has had a calf of her own [2] and who is under three years of age is called a heifer (/ ˈ h ɛ f ər / HEF-ər). [3] A young female cow that has had only one calf is ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Before 1790, beef cattle averaged only 160 kg (350 lb) net. Thereafter, weights climbed steadily. [8] [9] Cattle breeds vary widely in size; the tallest and heaviest is the Chianina, where a mature bull may be up to 1.8 m (5 ft 11 in) at the shoulder, and may reach 1,280 kg (2,820 lb) in weight.

Bulling is a behaviour seen in cattle (and other mammals) when one mounts another, usually when one or the other is a female in oestrus (on heat); [1] "bulling" is commonly used as a term for a female in oestrus. Female cattle in oestrus may mount any adult cattle, especially a bull (fertile male) if one is present, but they will also mount ...
