Abstract:
An experiment was conducted to evaluate the performance and blood biochemical parameters of Daothigir birds under intensive system of management. A total of 300 number of day-old chicks were reared in the farm premises of AICRP on poultry breeding Khanapara, under deep litter system of management with standard managemental practice. Blood biochemical parameters were recorder as Total protein (g/dL) 3.49±0.19, serum cholesterol (mg/dL) 77.25±8.78, serum bilurubin (mg/dL)23.59 ± 3.12, SGOT (IU/L) 221.76±15.24, SGPT (IU/L) 7.43±1.05, serum calcium (mg/dL) 7.98±0.86, serum phosphorous (mg/dL) 5.59±0.58, blood glucose (mg/dL) 158.23±9.78.The different performance traits measured were body weight of the birds at day old, 5th week, 20th week, 40th week and 52th week of age. Conformation traits and FCR at 5^th week of age, age at maturity, egg weight at 32^nd, 42^nd, 52^nd, 72^nd weeks of age, egg production upto 40th, 52nd and 72nd week, fertility and hatchability of egg, carcass characteristics and egg quality. Body weight at day old of combined sex was recorded as 26.25±1.21 g. Daothigir chicken gained 1031.49±98.43 g body weight at 20^th week of age. The Feed Conversion Ratio, breast Angle, shank length and keel length recorded at 5th week of age were 3.15, 42.10°, 6.16±0.79 cm and 5.98±0.84 cm respectively. At the end of 72^nd week the egg production was recorded as 121.59±10.67 numbers. Albumen index, yolk index and haugh units recorded at the end of 72nd week in the present study were 3.71±0.59, 0.47±0.09 and 80.24±5.12 respectively. The dressing and giblet percentage for both male and female recorded in the present study are 71.81±3.45, 70.29 ±5.19 and 5.13±0.38, 4.86±0.74 respectively. Therefore, it can be concluded that Daothigir has the production potential for higher production which needs to be exploited through selection, feed supplementation, creating awareness among the farmers. The results of the study will be helpful for accurate interpretation of biochemical tests of the indigenous poultry breeds.
