type of rabbit
Lionhead
The Lionhead rabbit is one of the newest breeds of domesticated rabbits. It has a furred body, but Angora-like wool surrounding the face, reminiscent of the mane of a male lion, hence the name. There may also be wool along the flanks, though this is not a desirable characteristic. Lionheads come in many of the same colors as other breeds. However, the wool on the mane and flanks diffuses the color, so that black rabbits will often have gray-looking manes and flank wool.
The Lionhead rabbit is a compact breed, usually weighing between 2.5 and 4.0 pounds. It also tends to have a rounded head and slightly shorter ears than most breeds.
The Lionhead rabbit is thought to have originated in Belgium. It is reported to have been produced by breeders trying to breed a long coated dwarf rabbit by crossing a miniature Swiss Fox and a Belgian dwarf. The Lionhead seemed to have been more popular than the long coated dwarf, and so breeders carried on this trend in breeding them intentionally, and so came what we know today as the Lionhead rabbit.
The "Lionhead" mane appearance comes from a mutation of the M-gene in rabbits. It exhibits a simple dominant expression, with MM resulting in a "double-maned" lionhead, and a Mm resulting in a "single-maned" lionhead. The single-maned lionhead will usually exhibit the breed's characteristic wool growth around the head and chest, potentially with some wool growth in other areas such as the flanks. The double-maned lionheads will have extensive wool growth in most areas besides the back.[9] The breed standard demerits for growth in uncharacteristic areas like the flank and out right eliminates rabbits due to wool high on the ears.[10] This standard prevents most double-maned lionheads from successfully showing, and thus most show rabbits are single-maned lionheads.
While single-maned Lionhead kits look like other rabbits, double-maned kits are distinct from all others. When they are born, they are bald around the abdomen, sides, bottom, and cheeks, giving them a peculiar "mohawk" appearance. The bald areas are where the wool grows in later as they mature.
This rabbit has an energetic, but sweet personality. They are great loving pets. But they do tend to act conceited.They are for the more experiened rabbit owner. Lionhead rabbits are easy to breed and are good mothers, even fostering kits from other litters or breeds.
The breed has been recognized by the British Rabbit Council, however, as of yet it is not a fully recognized breed by the American Rabbit Breeders Assiciation. Theresa Mueller passed her first of three required presentations before the ARBA Standards Committee with Black, Black Tortoise and Ruby Eyed White at the 2010 National Convention. The current COD (Certificate of Development) varieties (20):Black, Blue, Chestnut Agouti, Chinchilla, Chocolate Agouti, Chocolate, Orange, Otter (all 4 varieties shown as one class),Red, Ruby-eyed White, Sable Marten, Sable Point, Seal, Siamese Sable, Smoke Pearl, Pointed White(all 4 varieties shown as one class), Squirrel, and Tortoise(each variety to be shown separately): Black, Blue, & Chocolate are showable at most ARBA shows in the exhibition class.
Lop Bunnies
Among the oldest breeds of domesticated rabbits, lops are known for their distinctive floppy ears. There are five types of American Rabbit Breeders accepted lop varieties as well as a few other breeds being created. The ARBA recognized lop breeds are the French Lop, English Lop, Mini Lop, American Fuzzy Lop and the Holland Lop. In the UK the Dwarf Lop is the equivalent of the US Mini Lop, and the US Holland Lop is called a Miniature Lop in the UK. In the US, two of the proposed new breeds that are under development are the Velveteen Lop which is similar to an English Lop with a Rex rabbit's plush fur, and the Plush Lop which is similar to a Mini Lop with plush Rex rabbit fur.
The smallest of these is the Holland Lop [in the US otherwise known as the Miniature Lop] in the UK weighing around 3 lb (1.4 kg) and being a close relative of the Netherland Dwarf. The next largest is the Mini Lop in the US which has a weight range of 4½ to 6½ pounds, followed by the English, German, Meissener and French Lop breeds. The Meissener is a very rare breed available in only a couple of colours and is hardly ever seen at shows. They weigh around 3 and 1/2 and live to be approximately eight years.
Mini Lop
It is a different breed from the Holland Lop, which is the smallest (and only dwarf lop) of lop breeds in the USA.
Its equivalent in the UK is the Dwarf Lop; however there is a breed called the Miniature Lop in that area, which is the equivalent of the Holland Lop in the United States.
Miniature Lop
There are also miniature Lop Rabbits with cashmere fur called Miniature Cashmere Lop (Lop Breeds-No.2) and miniature Lop Rabbits cross-bred with Dwarf Lionheads called Miniature Lion Lop (Lop Breeds-No.9).
The Miniature Lop, is often called the Mini Lop in the UK, however, it is a different breed from US Mini Lop. The Miniature Lop is the equivalent of the US Holland Lops, however it can be smaller than the US Holland Lops.
The fur should be rollback, dense, fine, glossy, and about 1 inch long. To be showed a Miniature Lop should have a flat face, and sit up in a distinct manner. This breed often makes a very good pet due to their generally friendly temperament. Female Rabbits should start having babies at 6 months old.
New Zealand rabbit
New Zealand rabbits are available in three colors white, red, black, and broken. Although, cross breeding can result in many different combinations of these three basic pigmentations. There are efforts with certificates of development on a blue and broken variety. The Red has bright golden red fur with a slightly harsher fat. One of the larger breed of rabbit, it can weight anywhere from 9 lb. to 12 lb (5 kg).

Info Mengenai Arnab
Arnab atau kelinci merupakan sejenis haiwan mamalia yang tergolong dalam famili Leporidae yang tergolong dalam order Lagomorpha. Arnab mudah dikenali dengan telinganya yang panjang dan tirus, gigi acip tengah yang ketara dalam mulut, kaki belakangnya yang besar berbanding kaki depan, serta ekornya yang pendek. Arnab boleh hidup secara liar mahupun dijadikan haiwan peliharaan atau ternakan yang memberikan sumber makanan kepada manusia.
Dalam bahasa Melayu, perkataan "arnab" berasal dari bahasa Arab, iaitu arnab[1] (أرنب). Perkataan "kelinci" pula lebih banyak digunakan dalam bahasa Indonesia, dan berasal dari bahasa Belanda, yakni istilah konijntje yang bererti "anak arnab".[2] Apapun, ini jelas menunjukkan bahawa masyarakat Nusantara mula mengenali arnab atau kelinci daripada perdagangan antarabangsa pada zaman silam, padahal di Pulau Sumatera ada satu spesies arnab asli (Nesolagus netscheri) yang baru ditemui pada tahun 1972.[3] Nama saintifik famili "Leporidae" pula berasal dari perkataan lepus, iaitu arnab dalam bahasa Latin.
Pembiakan
Arnab mempunyai kadar pembiakan yang besar sekali. Musim membiak bagi kebanyakan arnab adalah 9 bulan, dari Februari hingga Oktober. Di Australia & New Zealand, musim membiak adalah dari akhir Julai hingga akhir Januari. Tempoh kebuntingan biasanya adalah 30 hari, ataupun lebih lama lagi bagi arnab dalam genus Lepus. Arnab biasanya boleh melahirkan 4 hingga 12 ekor anak, tetapi baka yang lebih besar mampu melahirkan banyak lagi arnab. Seekor anak arnab boleh bercerai susu sebaik mencecah umur 4 hingga 5 minggu. Ertinya, dalam satu musim, seekor ibu arnab boleh melahirkan sebanyak 800 anak, cucu dan cicit. Arnab betina sedia membiak pada usia sekitar enam bulan, dan arnab jantan pula sekitar tujuh bulan. Arnab mengambil masa yang sangat singkat untuk pikat-memikat dan mengawan, iaitu selama 30 hingga 40 saat. Kelakuan arnab ketika pikat-memikat melibatkan jilat-menjilat, hidu-menghidu, dan si jantan mengejar si betina. Arnab juga sering menyembur kencing sebagai kelakuan seksual. Arnab betina mungkin keguguran bulu bergumpal-gumpal sewaktu tempoh hamil.
Proses penghasilan ovum bermula 10 jam selepas mengawan. Selepas mengawan, arnab betina membuat dan mengalas sarangnya dengan bulu dari gelambir, rusuk dan perutnya. Kelakuan ini juga mendedahkan puting arnab betina untuk membolehkannya menetek anak-anaknya. Dalam kebanyakan spesies, anak arnab lahir buta, dogel, dan tidak berupaya (kecuali spesies-spesies dalam genus Lepus dan Sylvilagus yang anaknya sudah berbulu, boleh membuka mata dan mampu menjaga diri sebaik sahaja dilahirkan). Keimunan pasif (keimunan yang diperoleh melalui pemindahan antibodi atau limfosit peka daripada haiwan lain) diperoleh oleh anak arnab sebelum lahir melalui pemindahan plasenta. 10 atau 11 hari selepas lahir, anak arnab boleh membuka mata, kemudian ia boleh makan sendiri sekitar usia 14 hari.
Walaupun dogel ketika lahir, namun bulu anak arnab mula tumbuh dalam masa beberapa hari sahaja. Pada umur 5 hingga 6 minggu, bulu anak arnab yang lembut ini diganti dengan bulu pra-dewasa. Sekitar umur 6 hingga 8 bulan, bulu pertengahan ini diganti pula dengan bulu dewasa sepenuhnya, selepas itu arnab bersalin bulu dua kali setahun. Oleh sebab susu arnab sangat berkhasiat, anak arnab hanya perlu ditetek selama beberapa minit, sekali atau dua kali sehari.[15]
Jangka hayat arnab adalah kira-kira 9–12 tahun;[16][17] arnab yang paling panjang usia di dunia mencapai 18 tahun.[18]
Sama seperti rodensia (tikus dan sebagainya), arnab mempunyai sepasang gigi acip depan yang kuat, tetapi juga dilengkapi sepasang lagi gigi acip di kedua-dua belah gigi besar pada rahang atas, apatah lagi struktur giginya berbeza daripada gigi acip rodensia. Sama dengan rodensia juga, arnab tiada gigi taring, tetapi pipinya lebih berisi daripada rodensia. Rumus kegigian kebanyakan spesies arnab ialah
Arnab meragut dengan sekuat-kuat dan secepat-cepatnya pada separuh jam pertama waktu meragut (biasanya pada lewat petang), diikuti pemakanan yang lebih berpilih pada separuh jam seterusnya. Pada waktu ini, arnab juga mengumuhkan biji-biji tahi yang keras dan tidak dimakan semula. Jika persekitarannya tidak begitu mengancam, arnab boleh berada di luar sarang berjam-jam lamanya, dan sekali-sekala meragut makanan. Ketika di luar sarang, adakalanya arnab memakan semula biji-biji kumuhan lembut yang separa tercerna. Kelakuan ini jarang dapat diperhatikan kerana biji-biji tersebut dimakan semula sebaik sahaja dikumuhkan. Pemakanan semula ini paling biasa berlaku sekejap-sekejap dalam sarang dari pukul 8 pagi hingga 5 petang.
Bijian keras terbentuk daripada cebisan kulit ari dan tangkai tumbuhan yang seakan rumput kering, iaitu hasil buangan akhir selepas bijian lembut dimakan semula. Tahi keras ini hanya dikumuhkan di luar sarang dan tidak dimakan balik. Tahi lembut biasanya dihasilkan beberapa jam selepas meragut rumput, iaitu selepas semua tahi keras dikumuhkan. Tahi lembut ini terdiri daripada mikro-organisma dan dinding sel tumbuhan yang tak tercerna.
Bahan tumbuhan yang terkunyah berkumpul dalam sekum besar, sebuah kebuk sekunder di antara usus besar dan kecil yang berisi sejumlah besar bakteria simbiosis yang membantu pencernaan selulosa serta menghasilkan vitamin B tertentu. Biji tahi ini terdiri daripada 56% bakteria pada berat kering, dan oleh itu mengandungi purata 24.4% protein. Biji-biji ini kekal utuh selama enam jam dalam dalam perut, sementara bakteria dalamnya terus mencernakan karbohidrat tumbuhan. Tahi lembut terbentuk di sini dan mengandungi vitamin yang sebanyak lima kali ganda dalam tahi keras. Selepas dibuang, tahi lembut itu dimakan bulat-bulat oleh arnab dan dicernakan semula di dalam perut. Proses pencernaan berganda ini membolehkan arnab menggunakan khasiat yang mungkin terlepas olehnya ketika mula-mula melalui usus, dan juga khasiat-khasiat yang terbentuk daripada kegiatan mikrob untuk memastikan supaya arnab memperoleh khasiat yang secukupnya daripada pemakanannya.[5] Proses bagi arnab ini sama tujuannya dengan peruminatan bagi lembu dan kambing.[22]
Arnab tidak boleh muntah kerana dilarang oleh fisiologi sistem pencernaannya.[23]

[sunting] Pemakanan
Hampir semua arnab merupakan haiwan maun (kecuali beberapa spesies Lepus),[19][20], yang gemar meragut rumput, herba, dan rumpai berdaun, tetapi juga memakan buah-buahan dan biji-bijian. Oleh itu, diet arnab mengandungi jumlah selulosa yang banyak dan sukar dicernakan. Masalah ini diselesaikan dengan mengumuhkan dua jenis tinja yang berbeza, iaitu tahi keras dan biji-biji hitam lembut likat yang dimakan segera. Arnab memakan semula bahan buangannya sendiri (tidak mengunyah mamahan seperti yang dilakukan oleh lembu dan haiwan maun yang lain) untuk mencernakan lagi makanannya serta memperoleh khasiat yang mencukupi.[21]Sama seperti rodensia (tikus dan sebagainya), arnab mempunyai sepasang gigi acip depan yang kuat, tetapi juga dilengkapi sepasang lagi gigi acip di kedua-dua belah gigi besar pada rahang atas, apatah lagi struktur giginya berbeza daripada gigi acip rodensia. Sama dengan rodensia juga, arnab tiada gigi taring, tetapi pipinya lebih berisi daripada rodensia. Rumus kegigian kebanyakan spesies arnab ialah
