Evaluation of Assamese buffaloes considering important economic traits under field conditions in their home tracts

Abstract

The Assamese buffaloes are being reared by the farmers/breeders for milk, meat and for draught purposes. These buffaloes are known for higher fat contents in their milk (8.5 percent on an average) and are famous in the market with a great demand and are known as “Khuti milk”. They are good source of livelihood for breeders and the graziers both in its breeding tract and have attracted researchers to consider the study of some important economic traits under field conditions. The present study was organized and considered the data on a total of 324 Assamese buffaloes distributed over three districts namely Kamrup, Nagaon and Darrang in Assam covering 35 khutis (open herds) during the year 2015-16 eighteen months. The lactation milk yield of Assamese buffalo was observed as 448.38±1.67 kg with a lactation length of 237.06±0.74 days and the peak yield and days to attain were measured as 3.41±0.02 kg and 54.16±0.19 days respectively. The reproduction traits like age at first calving, gestation period, service period and inter-calving period were considered for the study based on the breeders’ interview using pre-structured formats. The age at first calving was recorded as 52.28±0.81 months, the gestation period was observed as 323.10±0.68 days with an inter-calving period of 465.70±1.67 day. The service period and the dry period for these buffalo was 171.34±0.82 and 252.84±1.47 days respectively. The production and reproduction performance of Assamese buffaloes need special attention to be addressed for further improvements to help a large size of population of Assam, who are entirely depending for their livelihood on these valuable AnGR (buffaloes) of Assam.
