Researchers have been attempting to control estrous cycles in animals for the last 50 years. For the past several years, there has been considerable interest in the use of Lutalyse for estrous synchronization in beef cattle. For synchronization and artificial insemination to be successful, quality management and nutrition programs must be utilized. Some individual reports have indicated low reproductive performance can be accounted for by noncycling cows, poor management and semen handling techniques efficiency.
This study includes data from the 1980, 1981 and 1982 breeding seasons using Lutalyse to synchronize estrous in beef cattle. The purpose of this research was to evaluate the effectiveness of Lutalyse on beef cattle using a single Lutalyse injection compared to two injections given 11 days apart.
