Goat evolution is the process by which domestic goats came to exist through evolution by natural selection. Wild goats — medium-sized mammals which are found in noticeably harsh environments, particularly forests and mountains, in the Middle East and Central Asia — were one of the first species domesticated by modern humans, with the date of domestication generally considered to be 8,000 ...
As indicated above, some mammals typically used for food production (such as goats, sheep, pigs, and cows) have been modified to produce non-food products, a practice sometimes called pharming. Use of genetically modified goats has been approved by the FDA and EMA to produce ATryn, i.e. recombinant antithrombin, an anticoagulant protein drug. [20]
The goats are easier to handle in large groups than spiders and thus this could potentially increase the efficiency of silk production and consumer cost. [2] This technology is also being used to make bio-diesel to power cars. Biotech company, Amyris, in Emeryville, California, has applied synthetic biology to yeast.
Goats produce about 2% of the world's total annual milk supply. [63] Dairy goats produce an average of 540 to 1,180 kg (1,200 to 2,600 lb) of milk during an average 284-day lactation. [64] The milk can contain between around 3.5% and 5% butterfat according to breed. [65] Goat milk is processed into products including cheese [66] and Dulce de ...
A genetic chimerism or chimera (/ k aɪ ˈ m ɪər ə / ky-MEER-ə or / k ɪ ˈ m ɪər ə / kim-EER-ə) is a single organism composed of cells with more than one distinct genotype. Animal chimeras can be produced by the fusion of two (or more) embryos .
Goat breeds (especially dairy goats) are some of the oldest defined animal breeds for which breed standards and production records have been kept. Selective breeding of goats generally focuses on improving production of fiber, meat, dairy products or goatskin. Breeds are generally classified based on their primary use, though there are several ...
There have been incidents of polycerate goats (having as many as eight horns), [9] although this is a genetic rarity thought to be inherited. The horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. 4 horns are the norm for the Austrian goat breed Vierhornziege (four-horned goat). [10]
While goat and cattle leather have a wide variety of use, sheepskin is suited only for clothing purposes. [75] Wool from Merino hoggets is the finest and most valuable. Merino wool is 3–5 in (7.6–12.7 cm) long and very soft. Coarse wools, being durable and resistant to pilling, are used for making tough garments [76] and carpets.
