At Ziwani Poultry we are now selling a new breed from Hubbard, the JA57 Ki. The JA57 Ki is a recessive female which allows the offspring bred from these breed to possess the male’s phenotype; meaning, all the chicks will look like the male (cock), therefore is the male is black, all the chicks will be black.
There are other range of 3 females with different characteristics. But we decided to use the JA57 Ki. JA 57 Ki: boasts the best PS productivity, with more than 227 eggs. at 68 weeks, and allows chicks to be feather sexed. The chicks are slow growing broilers just like the Kenbro, but they can be reared as kienyeji. They adapt easily as free ranged and are resistant to disease.
The Kenbro as we know it in Kenya is a breed from Hubbard, they supplied the Redbro to Kenchick who then called it Kenbro.
We use brown and black Differentiated Growth males. These are able to satisfy the requirements of farmers seeking marketable live weights of 1.4 to 3.0 Kg at a minimum age of 40 to 70 days. That is around 2.5Kgs in 60 days or 2 months, when well feed according to Hubbard’s Guidance ManualGoogle+
