The aim of this study was to investigate the disease problem, mortality pattern and live weight performance of broiler chicken flocks raised in the rural farms of Assam and compare the results of current study with the corresponding data obtained from an instructional farm. On the basis of obtained results level of income generation by farmers from the sale proceeds was also determined in this study. The rural farms witnessed higher (17.21%) mortality than that of instructional farm (2.16%). Average live weight performance of birds at a market age of 49 days was 2.34 kg/bird in the rural farms against an average record of 2.79 kg/bird in the instructional farm. Post-mortem examination of dead birds showed that the farms were affected with coccidiosis (44.44%), colibacillosis (22.22%) hydropericardium syndrome (15.55%), gout (13.33%), brooder pneumonia (8.88%) and enteritis (6.67%) of which enteric infections were found to be the major cause of death. Experimental subclinical coccidiosis resulted an average 451.67g less weight gain compared to healthy controls and this also paralleled to the lower performance observed in the rural farms. The farmers were found to incur 15.38% and 13.65% losses of sale proceeds obtained in instructional farm due to higher mortality and lesser weight gain respectively with a total 29.03% income loss. The findings of the study warrant technical support to untrained farmers in the neglected areas of litter management, health care and disease prevention for a better prospect towards improving the farmers’ income. * Corresponding author KEYWORDS
