Livestock produce gaining popularity in recent years is helping in sustainable livelihood security and poverty alleviation. It has given rise to the need for a critical analysis on various aspects of climate, sustainability, preference and performance etc. With a stratified random sampling technique a study was conducted in Dibrugarh, Kamrup and Bongaigaon districts of Upper Assam, Middle Assam and Lower Assam respectively in flood affected blocks selected for data collection. At the village level, random sampling method on the basis of lottery was adopted to select the respondents. Precision investigations were ensured by the check lists and methods specially prepared for the purpose of this study. Information was collected personally by the researchers in a pre-tested, reliable and valid interview schedule containing the features of micro climate indicators. The data such collected were arranged, tabulated and analyzed so as to arrive at useful conclusion and interpretation. Flood was recognized as the most important factor affecting livestock in all the three districts. The micro-climate factors affecting livestock production had no significant mean difference among the districts in Assam. The major micro-climatic factors affecting livestock production in order of their impact were Flood (6.09%), Less availability of grass (5.82%), Parasitic infestation (5.72%), Education (5.66%) and Draught (5.56%). Flood had significant affect and the five critical indicators of micro-climate could express as high as 35.00 per cent of the variations in livestock production, although there was a significant difference as far as R value (1.75*) was concerned.
