KARI improved Kienyeji was bred by the Kenya Agricultural Research Institute(KARI), now known as Kenya Agricultural and Livestock Research Institute (KARLO) at their research center in Naivasha, with collaboration with researchers from Egerton University, Njoro.

Research and Breeding of the KARI improved Kienyeji started in 2002, where breeders at the KARI research center wanted to come up with an improved chicken breed that had the characteristics of indigenous chicken, gains weight faster and matures fast.

After three years of intense research, KARLO came up with a pure indigenous breed that would have better productivity than indigenous breeds. The Kari Improved Kienyeji was the name of the new breed, that lays between 200 and 280 eggs, as compared to commercial layers that lay 300 eggs per year. It has better meat quality, less overhead costs, and greater disease resistance when compared to their commercial counterparts.

KALRO then perfected the breed over 7 more years and KARLO improved Kienyeji was launched into the market in 2012.

Kari Improved Kienyeji is 100% indigenous chicken. It was not a product of crossing indigenous breeds with exotic breeds but a result of breeding different indigenous parents with good characteristics. 

KARI Improved Kienyeji Background Information

The main objectives for the researchers in the ASAL department of KARLO were to produce a breed that would keep the characteristics of indigenous chicken, with more productivity than the indigenous chicken and can be kept all over Kenya, especially in the Arid and semi-arid areas of Kenya.

They took time to research the characteristics of village chicken all over Kenya vis a vis exotic layers and broilers and used that as a benchmark for the breed they were working on.

The breed gained popularity and by 2016, Kari had distributed over 300,000 day-old chicks. 40,000 month old, 1000 breeding cocks and 3800 hatching eggs.
