Ayam Cemani Standard Of Perfection

Classification: All Other Standard Breeds AOSB 

Officially recorded as a Javanese breed in the 1920s, Ayam Cemani have quickly become a highly intriguing fowl due to its deeply pigmented flesh, mystical healing properties, and ornamental allure. Ayam Cemani derived from centuries of strict selective breeding and cultivation of a naturally occurring genetic mutation found in the indigenous chickens and jungle fowl of Java, Indonesia. 

Fibromelanosis (often referred to as fibro) is a dermal hyperpigmentation that can be found in a number of breeds mostly originating from Asia. Mutation and duplication of fibromelanosis, results in excessive accumulation of black pigment within the skin, bones, meat, organs, and connective tissue of the fowl. With the defining characteristic of Ayam Cemani being thorough expression of fibromelanosis; selective and competitive breeding for deeply saturated fibro has captivated breeders & enthusiasts worldwide. 

Ayam Cemani are a medium sized fowl, with a trim form, that boasts of strength and virility. Draped in lustrous iridescent black feathers, the breed calls for a single comb extending off the back of the head with 5 distinct points and tightly carried wings, slightly lower than the horizontal plane of the fowl. With a more upright stance and broad chest, Ayam Cemani have a closer resemblance to gamefowl, as opposed to heavier landrace breeds.
