This study was conducted to compare the effect of different brooding techniques on production performance and physiological parameters of broilers. One hundred eighty day old broiler chicks were purchased from a local hatchery and were randomly divided into 9 experimental units (replicate@ of 20 chicks each. These units were further allotted to -three treatments (A, B, & C@ having three replicates each. Brooding in treatment A, B and C was conducted by using Electric heating, Gas and Wood respectively as fuel sources in three separate rooms of same specifications. All the experimental birds were provided standard husbandry conditions like light, space, ventilation and relative humidity, the data regarding body weight, feed consumption, feed conversion ratio, mortality and incidence of ascites and other pathological conditions was recorded. Respiration rate, rectal temperature and room temperature were recorded daily. At the end of experiment two birds from each replicate were randomly picked up and slaughtered for dressing percentage and relative weights of liver, lungs, heart, gizzard and spleen. Blood serum samples were collected to check, glucose, cholesterol and antibody titer against Newcastle and Gumboro diseases. Analysis of variance showed a highly significant difference with respect to weight gain, feed consumption and feed conversion ratio, respiration rate (morning and evening@, antibody titer against ND and IBD at 21 & 42 days of the chicks. Statistical analysis of the data also revealed non-significant effect of treatments on the average values of dressing %age, liver, heart, gizzard, spleen and lungs weight, rectal temperature (morning & evening@, serum cholesterol and glucose level at 42-days of age. The production cost per broiler was 98.02, 93.32, and 101.5 Rs. in birds kept under A (Electric@, B (Gas@ C (Wood brooding systems, respectively. The net profit per bird was found to be 18.98 (electric@, 23.08 (Gas@ and 12.3 Rs. in (Wood@ brooding system respectively.
