Cay Cum chicken is the indigenous breed raised in the north mountainous areas. The typical characteristics of this breed are lower tailwithout rumphigh quality of meat and flavors. The objectives of this study was to identify the affect of raising mode on the growthfeed conversation ratioeconomic number of Cay Cum chicken and confribute to conservation of this indigenous chicken breedhousehold economic development of ethnic people living in this areas. The study consisted 300 chickens from one day old to 20 weeks of agesthat were divided in three treatments (intensive raising
semi-intensive raising and traditional raising). The obtained results showed that (i) the raising mode affected to the growth of Cay Cum chickenamong that the highest was the intensive raisingthe following was semi-intensive and the last was traditional raising. The body weight of Cay Cum chicken at 20 weeks of age was 2,206.71g at the intensive2,021.20g at the semi - intensive and 1,618.06g at the fraditional raising mode
(ii) The ability of feed intake and feed conservation ratio of Cay Cum chicken raised by the intensive and the semi-intensive mode were better than traditional mode. At 20 week of ageFCR of the intensive mode was 4.08 kg
the semi-intensive mode was 4.30 kg and the traditional mode was 5.25kg
(iii) The production number (PN) and economic number (EN) of the intensive and the semi-intensive mode were better than traditional mode (43.93 and 41.36 compared 26.57 for PN and 0.14 and 0.13 compared with 0.08 for EN). In mountainous conditionsCay Cum chicken breed shoulds be raised in the semi-intensive mode.Gà Cáy Củm là giống gà bản địa được nuôi tại các tỉnh miền núi phía Bắc.
