Abstract
A cross breed chicken is a breed of higher productivity as well higher adaptability to native environment. They can serve us highly proteinaceous foodstuff. Two hundred forty day old CSML X Hansli cross bred chicks were randomly distributed in 3 replicate groups to have 80 chicks per replicate group. They were given feed and water on ad-libitum basis. Then during the grower stage (8th -20th week), sex separated feeding was practiced. Male and female chicken were housed separately. Restricted feeding was practiced throughout the period. After completion of grower stage, around 80 female layers were taken and randomly distributed into 8 replicas. Feed was allotted to layers @ 110 g/ day/bird and the feeding continued from 21st to 52nd week. Proper vaccination schedule and medication were followed. Birds were reared up to 52 weeks of age. The following parameters such as Growth performance, Feed conversion efficiency, Mortality at different ages, Linear body measurement, Egg Production %, egg production performances, Age at sexual maturity in females, External egg quality parameters, Internal egg quality parameters were studied at different ages. The body weight of male and female of experimental cross at 8th week of age was 755.33±4.95g and 679.44±6.49g respectively. The body weight of male and female of the above cross at 20th week of age was 2403.94±61.72g and 1900.95±27.29g respectively. The FCR gradually increased from 1.72±0.01 at 1st week of age to 2.96±0.02 at 8th week of age. The FCR was significantly higher (p≤ 0.01) in male as compared to female at grower phase. The linear body measurements of male birds were significantly higher (p≤ 0.01) than that of female birds at all ages except shank width. The age at first lay of these birds was 170.00±0.27 days. The peak egg production 70.75±1.12 was obtained at 308.25±0.16 days. The egg weight increased significantly (p≤ 0.05) from 25th week of age (43.29±1.23) to 52nd week of age (53.00±1.73). The albumen index was 0.0957±0.007 at 30th week of age and 0.1026±0.003 at 52nd week of age. The above measured characters were compared with different crossbreeds and some native breeds which indicates dual purpose persona of these birds.
