A project in Huila, Colombia, is using Girolando plus cattle, a breed resulting from the manual mix of gyr and holstein genetics and created through in vitro fertilization, to improve milk production and quality in local farms. The best gyr females and holstein bulls are selected for this program, which has led to offspring capable of producing twice the milk of regular cows, especially in hot climates. The transfer of sexed embryos to recipient cows allows for more control over the type of offspring produced and can potentially save producers up to 14 years of raising cattle by providing similar results in just two years. The project also emphasizes the importance of vitamin and calcium supply, periodic purging, and comprehensive technological packages, including pasture improvement and sanitary management, for the successful rearing of these highly genetic animals.
