This article is about the domesticated species. There the kid stays in the picture pdf over 300 distinct breeds of goat. Goats are among the earliest animals domesticated by humans. 8000 and 9000 years ago.
Studies of DNA evidence suggests 10,000 years BP as the domestication date. Within each breed, different strains or bloodlines may have different recognized sizes. Unlike cattle, goats have not been successfully bred to be reliably polled, as the genes determining sex and those determining horns are closely linked. As with other mammal ruminants, they are even-toed ungulates. Goats reach puberty between three and 15 months of age, depending on breed and nutritional status.
However, this separation is rarely possible in extensively managed, open-range herds. Successful breeding in these regions depends more on available forage than on day length. 21 days for two to 48 hours. Bucks of equatorial breeds may show seasonal reduced fertility, but as with the does, are capable of breeding at all times.
Rut is characterized by a decrease in appetite and obsessive interest in the does. Sebaceous scent glands at the base of the horns add to the male goat’s odor, which is important to make him attractive to the female. Some does will not mate with a buck which has been descented. Birthing, known as kidding, generally occurs uneventfully. Just before kidding, the doe will have a sunken area around the tail and hip, as well as heavy breathing. She may have a worried look, become restless and display great affection for her keeper.
After the lactation, the doe will “dry off”, typically after she has been bred. Occasionally, goats that have not been bred and are continuously milked will continue lactation beyond the typical 305 days. The unusual smells of leftover food in discarded cans or boxes may further stimulate their curiosity. Aside from sampling many things, goats are quite particular in what they actually consume, preferring to browse on the tips of woody shrubs and trees, as well as the occasional broad-leaved plant. However, it can fairly be said that their plant diet is extremely varied, and includes some species which are otherwise toxic.
