Abstract

Gangatiri is a dual purpose cattle breed, found in Eastern Uttar Pradesh and Western Bihar along the river Ganga. It is medium milk producer and possess good draftability. These cattle are well adapted to low to medium input production system and produce about 2.5 to 8.0 Kg milk a day. The objective of the study was to identify the factors affecting variation in conception rate of Gamgatiri cattle inseminated under field conditions. Total of 2362 artificially inseminations of Gangatiri cattle were studied in Ara, Azamgarh, Buxar district during period 2009 to 2013. In district wise study conception rate in Ara was 54.98±3.72%, 67.78±2.31% in Azamgarh and 61.42±4.94% in Buxar. In economic status wise study, it was found that conception rate was 60.56±3.00% in Above Poverty Line (APL) and 62.22±2.95% in Below Poverty Line (BPL). In parity wise study in heifer conception rate was 60.64±3.19% while in first parity it was slightly higher 61.99±3.20. It was 62.73±3.39% and 60.21±3.82 in second and third parity. In year wise study conception rate was 62.27±4.52 in year 2009 and 59.11±2.81% in 2010. It was 58.90±3.43%,56.58±3.42% and 70.11±3.89% in 2011,2012 and 2013 respectively. In seasonal study conception rate was higher in rainy season 63.25±3.18% followed by Summer 60.98±3.04% and lowest in winter 59.95±3.19%. In AI sequence wise study conception rate was highest in first insemination 63.93±2.12% followed by in second 63.33±3.19% and lowest in third 56.92±5.98%. Out of all parameters only district and Insemination year was having significant effect.

Key words: Artificial insemination, Gangatiri, Conception rate, APl, BPL
