The study was to identify the reproductive performance of Vietnamese local chickens, named Noi chickens from 36 - 46 weeks of age. The study aimed to determine the effect of breeds and rearing system on laying performance and egg quality of local chickens. The study was a factorial design with 2x2 factors and involved with 120 layers. The first factor was 2 rearing systems (experimental free-range farming system in Tra Vinh province and local free-range farming system in Ben Tre province). The second factor was 2 breeds (egg and broiler purpose). The results showed that egg production rate, laying egg per week were significantly different between breeds and rearing systems (P<0.05) while feed intake was not different. The highest egg production rate recorded at week 44 with 38.42%. For egg quality, yolk diameter, yolk color and yolk index were different breeds and rearing system. It can be recommended that rearing system in Ben Tre province and egg purpose breed was better for egg production and quality.
