'''বোয়ের ছাগল''' হল ছাগলের একটি জাত। এটি ১৯০০এর দশকে [[দক্ষিণ আফ্রিকা]]তে বিকাশিত হয়েছিল এবং এটি মাংস উৎপাদন করা জাতগুলোর মধ্য অন্যতম। এদের নাম উদ্ভূত হয়েছে আফ্রিকার [[সুইডিশ]] শব্দ '''বোয়ের''' থেকে যার অর্থ কৃষক।

==Doe ==
A doe used to breed show-quality goats are normally very large. For commercial meat production, medium-sized 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 margin]]s for the owner. Boer goats are [[polyestrous]] (they can breed throughout the year), and they reach [[sexual maturity]] at five months of age. A typical breeding program is to produce three kid crops every two years, meaning the does are pregnant for five months, nurse their kids for three months, and then are rebred. Multiple births are common, and a 200% kid crop is achievable in managed herds. Usually, first-time does have one kid, but they may have more. After that, they usually have two kids every other breeding. The kids can be brown, black, white, or mixed.
 
== Crossbreeding ==
[[Image:Amarugia Golddigger.JPG|thumb|A 7/8 (F3) Boer goat, paint doe|সংযোগ=Special:FilePath/Amarugia_Golddigger.JPG]]
While [[purebred]] bucks are usually preferred for breeding purposes, crossbred does are commonly used 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]], Boer x [[Nubian goat]], Boer x [[Sirohi goat|Sirohi]], Boer x Osmanabadi, and Boer x [[Jamnapari goat]]. An effort to crossbreed with the [[Malabari goat]] has been controversial.<ref>{{Cite web|url=https://www.thehindu.com/thehindu/2002/12/16/stories/2002121601670500.htm|title=The Hindu : `Malabari' goats under threat of extinction|website=www.thehindu.com|access-date=2018-08-29}}</ref>
 
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 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 crossbreeding 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 preference. Bucks and does bred for show can be and often are used for commercial breeding stock.<ref>Bowman, Gail, Raising Meat Goats for Profit 0967038103</ref> To show, most Boer goats have to be registered with either the CMGA, ABGA, IBGA, or USBGA. Though Boer goats are often bred to be shown, they can also make very good pets.
