ABSTRACT
The present study was conducted on two indigenous layer breeds of India and the aim was to evaluate the data consisted of body weight up to 6 weeks, carcass traits at 5th week of age and immune response traits collected from a generation of Aseel and Kadaknath maintained at the Poultry Research Farm, GADVASU, Punjab. The average body weight of Aseel at 0 day, 1, 2, 3, 4, 5 and 6 weeks of age were recorded as 28.74±0.15, 56.57±0.38, 88.51±0.82, 129.31±1.31, 192.49±1.94, 253.75±2.65 and 346.98±3.93 grams, respectively and the average body weight of Kadaknath upto 6 weeks of age were recorded as 29.05±0.15, 54.75±0.40, 84.44±0.88, 113.49±1.26, 175.27±1.72, 235.38±2.32 and 322.51±1.06 grams. The difference in growth pattern between the layer breeds was not distinct until 3 weeks of age. From 4 weeks onwards Aseel showed linear increase in body weights until 6 weeks. Aseel was superior in different carcass traits viz. live weight (326.23±8.26), dressed weight (231.63±6.41), eviscerated weight (161.97±5.20), breast (37.37±1.84), thighs (28.27±0.96), drumsticks (27±0.96) and legs (55.27±1.88) which were significantly (p<0.05) higher than Kadaknath. The weight of different support organs viz. liver, gizzard, lung and intestine were not significantly different between the layer breeds except heart. Immune response to Sheep Red Blood Cells (SRBC) was measured in terms of Haemagglutination titre (HA) at three stages viz. 0 (pre inoculation), 5 and 10 days post primary inoculation (PPI) of SRBC. The HA titre on 10 day was significantly higher in Aseel (1.88±0.10) than Kadaknath (1.09±0.06). The in vivo cell mediated response to mitogen phytohaemagglutinin estimated using foot pad index was significantly higher in Aseel (0.68 mm) than Kadaknath (0.43 mm). Specific immune response to IBDV was estimated by ELISA using commercial test kit. The antibody titre for IBDV got increased during 7, 14, 21 days post immunization (DPI). At 14 DPI the titres were significantly different in two breeds in which Aseel exhibited the higher titre (2.96±0.04) than Kadaknath (2.64±0.06). It was found that at 21 DPI antibody response was highest in the two breeds, but not significantly different. Overall better growth, carcass traits and immune response to IBDV was found in Aseel than Kadaknath.
Key words: Immune responsiveness, Sheep Red Blood Cell, Phytohaemagglutinin, Aseel, Kadaknath.
