New Approaches of Estrus Synchronization to Improve Reproductive Performance in Dairy Animals

Pakistani Funding (HEC):  $98,093
US Funding (Department of State): $88,780
Project Dates: November 15, 2010 - November 14, 2012 (completed)
 
Project Overview
 
Of total milk production in Pakistan during 2008-2009, cows were the source of 34 percent and buffaloes 62 percent. Despite their merits, buffaloes have relatively poor reproductive efficiency, particularly when bred artificially. All these factors lead to long calving intervals and reduced milk production. The latest technologies can help overcome these problems, including methods for synchronization of estrus and ovulation, and the objective of this collaborative study is to determine the effect of several factors on follicular development, estrus expression, ovulation, and pregnancy rate with the ultimate goal of improving livestock reproductive rates. The research should also be useful on the US side as well, as optimal management of the reproductive efficiency of dairy cows is a major factor contributing to efficiency and profitability of dairy farms in this county. By combining their complementary expertise and experience in both research and extension work with dairy farmers, this team hopes to make progress on problems directly related to Pakistani government priorities aimed at increasing meat and milk production in the country. By carrying out some of the experimental work in collaboration with Pakistani farmers, they hope that the project results will create a ripple effect and encourage commercial dairy operators to adopt new strategies to increase their production and profitability and thus improve the lives of Pakistanis associated with the livestock industry.
