Boer goat
The Boer goat is a goat developed in South Africa in the early 1900s for meat production. Their name is derived from the Dutch word "Boer," meaning farmer. The Boer goat was probably bred from the indigenous goats of the Namaqua Bushmen and the Fooku tribes, with some crossing of Indian and European bloodlines being possible. They were selected for meat rather than milk production; due to selective breeding and improvement, the Boer goat has a fast growth rate and excellent carcass qualities, making it one of the most popular breeds of meat goat in the world. Boer goats have a high resistance to disease and adapt well to hot, dry semi-deserts. United States production is centered in west-central Texas, particularly in and around San Angelo and Menard. The original US breeding stock came from herds located in New Zealand. Only later were they imported directly from South Africa.
Boer goats commonly have white bodies and distinctive brown heads. Like the Nubian goat, they possess long, pendulous ears. They are noted for being docile, fast growing, and having high fertility rates. Does are reported to have superior mothering skills as compared to other goats. Mature Boer bucks weigh between 110–135 kg (240-300 lb), and mature does between 90–100 kg (200-220 lb).
Meat goats are minimal care animals that are browsers by nature, preferring brush, shrubs, and broadleaf weeds rather than grass. Boer goats raised for meat production are typically raised on pastures. The main reasons for this are twofold: pastured goats are on average healthier animals than pen-raised goats; secondly, it costs far less to raise Boer goats on a diet of brush and weeds, than on bags of commercial feed. The ideal option is adequate year-round grazing with only mineral supplementation. Boer goats can be raised effectively in combination with cattle or sheep due to their preference for browse and the resulting limited impact on the grass cover. They do compete with other browsers, such as deer.
Trace minerals, especially copper, are particularly important to good goat health. Feed and mineral blocks marked "for sheep and goats" should be avoided. Copper in quantities suitable for goats is toxic to sheep, so dual sheep/goat feeds will almost always lack sufficient copper for goats. Copper deficiency is known to cause anemia, diarrhea, infertility, spontaneous abortions, and lethargy.
Bucks:
The most critical part of any meat goat operation is the selection of a herd sire (breeding buck). A high quality buck can produce high quality offspring even when mated with an average doe. Boer goats tend to gain weight at about the same rate as their sire, so a buck from a proven fast growing bloodline will command the highest price, as its offspring will tend to also be fast growers. The primary market for slaughter goats is a 22–36 kg (50-80 lb) kid; kids should reach marketable size at weaning age. The kid of a proven fast-growing sire might weigh 36 kg (80 lb) at 90 days, while the kid of a poor quality sire might weigh only 15 kg (35 lb) at 90 days. An average quality buck will initially be less expensive to purchase; however, they can significantly undermine an operation's long-term profitability. Other criteria for a breeding buck include:
Jaw alignment – most meat goats are raised on pasture. A goat with poor jaw alignment will be at a significant disadvantage when feeding on pasture; poor jaw alignment is not acceptable in a commercial herd sire.
Good feet and legs: needed to move about the pasture. Hoof rot is a common problem for goats that live in high rain areas if the hooves are not clipped regularly.
Two well formed equal-size testes in a single scrotum: the main purpose of a buck is to breed does.
For breeding purposes, one buck is normally required for every 25-35 does. Under ideal conditions the ratio can be as high as one buck for every 50 does. Bucks are normally separated from the does except for when breeding is specifically intended. Often does are bred for six weeks every 8 months, resulting in three kid crops every two years.
Successful bucks must be able to survive on pasture. Pen-raised bucks will stay near their pen, while the does they are supposed to breed are out in the pasture.
Does:
Does used to breed show quality goats are normally very large, as show goats are expected to be of large stature. For commercial meat production medium size does are normally preferred as they produce the same number of kids, but require less feed to do so.
As a general rule the more kids born per doe, the greater profit margins for the owner. Boer goats are polyestrous (they can breed throughout the year), and they reach sexual maturity at 5 months of age. A typical breeding program is to produce 3 kid crops every 2 years; meaning the does are pregnant for 5 months, nurse their kids for 3 months, and then are rebred. Multiple births are common and a 200% kid crop is achievable in managed herds. Usually first time does will have one kid, but it is possible for them to have more. After that, they will have an average of two kids each time.
Weaning size is largely controlled by how much milk the mother produces, along with how long she allows each kid to nurse. Does weaning large kids should be kept, those weaning small to medium kids should be removed from the herd.
The presence of a buck causes does to come into estrus (heat), which lasts about 24–36 hours. The gestation period for does varies from 149 to 155 days.
Boer does are normally very good mothers, requiring only minimal attention from the owner; however, this is not always true when a doe delivers her very first kid. First time does should be supervised, as the mothering instinct may not manifest itself the first time she delivers. After the first time, Boer does normally make excellent mothers. If after that a doe does not present herself to have "mothering instincts", it is best not to keep her.
Cross breeding:
While purebred bucks are usually preferred for breeding purposes, it is common to use crossbreed does for kid production, with the resulting offspring being 7/8 or more Boer. Common crosses are Boer x Spanish goat, Boer x Angora goat, Boer x Kiko goat, and Boer x Nubian goat.
Percentage Boer goats are very common in commercial meat herds, and with those just starting out in the Boer goat business due to ease of acquisition and affordability. Over time, percentage animals can be bred up to American purebred status. An American purebred is a Boer goat of 15/16ths Boer blood (F4) for does and 31/32nds blood (F5) for Boer bucks. Bucks must be one generation of Boer breeding higher than does to achieve this status because they have the potential to spread their genetic pool much further than any single doe; a higher level of Boer blood lessens the chances of other breed qualities in the offspring. Although American purebreds can never be registered as Fullblood (FB), many breeders will still use a good American Purebred buck with excellent results.
Many producers still prefer purebred or fullblood bucks and does, and intentional crossbreeding is far from universal.
Note: The 'F' designation is the commonly used shorthand for indicating the percentage of pure blood (boer in this case) resulting from cross breeding of a Pureblood boer buck with does of other breeds:
F1 : 1/2 boer blood (Pureblood buck sire, other breed doe)
F2 : 3/4 boer blood (Pureblood buck sire, F1 doe)
F3 : 7/8 boer blood (Pureblood buck sire, F2 doe)
F4 : 15/16 boer blood (Pureblood buck sire, F3 doe)
F5 : 31/32 boer blood (Pureblood buck sire, F4 doe)
Show goats:
Although Boer goats raised specifically for show purposes may seem to have little in common with pastured commercial goats, the difference is superficial. They are bred to be larger than normal goats, and meet specific visual appearances, but these very characteristics are valuable genes to add to the commercial herd. Boer goats were originally imported into the US and other countries for this very reason. Their value to ranchers lies in the improvement the addition of their unique genes can offer any breed of goats being raised for meat. Few producers could afford to maintain a herd of essentially useless animals. Show goats are bred to represent the most desirable characteristics of the Boer goat. And their main purpose is to introduce these animals to the public. It is also a method of recognizing the best of the best, although some really superior goats are not shown due to owner preference. Bucks and does that have been bred for show can be and often are used for commercial breeding stock. To show, most Boer goats have to be registered with either the ABGA, IBGA, or USBGA.
Horns:
There is no evidence to support the claim that a goat's horns act as a "cooling mechanism" to regulate body or brain temperature. Many people try to back up their argument by pointing out the fact that a goat's horns have blood vessels inside of them. This is because horns are bones and like any other bone, they have blood vessels inside of them. Claiming that horns regulate a goat's body or brain temperature is like claiming that your ribcage regulates the temperature of your organs.
Horns are used to scratch with but are also used to fight with. This can lead to injury such as broken bones and lacerations. A goat's horns can tear a female goat's udder damaging it permanently, but this is uncommon in Boers. Some goats use their horns against people, but Boer goats are known for being docile and rarely, if ever, use their horns against people. Exceptions to this may be if a female goat is protecting her kid(s), or if a buck is "in rut" (getting ready to breed), but even then this is unlikely.
Horns can also get stuck in fences or feeders, which, if not untangled, can lead to injury, or very rarely, death.
Even though you can dehorn goats, many people do not find the risk of infection and the pain it causes the goats, worth it. Methods of dehorning usually cause severe pain to the goats. Using a general anesthetic is not recommended as goats do not react well to it, and sometimes do not wake up as a result.
Most breeders do not dehorn their Boer goats. Usually dehorning is done on dairy breeds because of their very large udders which can easily be damaged by other goats' horns.
If you are reading this section on horns, and are unsure whether or not to dehorn your Boer goats, it is recommended that you do some research and read a few books on Boers before you make your decision.
