This article is about the domesticated species. There are over 300 distinct breeds of goat. Goats are among the goat farming project pdf 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. The horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. 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. In various places in China, goats are used in the production of tea. The goats’ droppings fertilise the tea plants. At birth, the rumen is undeveloped, but as the kid begins to consume solid feed, the rumen soon increases in size and in its capacity to absorb nutrients.
Large-framed goats need more calories than small-framed goats for maintenance of daily functions. File:The goats behavior within a herd. An example of the goats’ social behavior within a flock. They are also agile and well known for their ability to climb and balance in precarious places. Due to their agility and inquisitiveness, they are notorious for escaping their pens by testing fences and enclosures, either intentionally or simply because they are used to climb on. If any of the fencing can be overcome, goats will almost inevitably escape. Due to their intelligence, once a goat has discovered a weakness in the fence, they will exploit it repeatedly, and other goats will observe and quickly learn the same method.
When handled as a group, goats tend to display less herding behavior than sheep. When grazing undisturbed, they tend to spread across the field or range, rather than feed side-by-side as do sheep. Goats were first domesticated as livestock more than 10,000 years ago. Research conducted to test communication skills found that the goats will look to a human for assistance when faced with a challenge that had previously been mastered, but was then modified. Specifically, when presented with a box, the goat was able to remove the lid and retrieve a treat inside, but when the box was turned so the lid could not be removed, the goat would turn and gaze at the person and move toward them, before looking back toward the box. This is the same type of complex communication observed by animals bred as domestic pets, such as dogs. Researchers believe that better understanding of human-goat interaction could offer overall improvement in the animals’ welfare.
