Paperback. Condizione: New. Print on Demand. This fascinating book chronicles an experiment that began in 1911, in which common grade dairy cows were selectively bred over generations with pure-bred sires of either Ayrshire or Holstein breed. The author meticulously documents the milk production levels and profit margins of both the offspring and their dams across five lactation periods. This provides valuable insights into the significant benefits of using proven sires with established milk production lineage to improve the profitability of a dairy herd. The book also illustrates the importance of carefully selecting and retaining the most productive individuals and highlights the impact of a sire's genetic makeup on the type, color, and production characteristics of their progeny. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Condizione: New. Print on Demand. This book meticulously analyzes data collected over 16 years from an experiment in selective breeding to improve milk production and profit. The author uses this data to demonstrate the significant impact of using purebred sires on the development of a profitable dairy herd, even when the foundation cows are of mixed or common stock. The book underscores the importance of careful sire selection, emphasizing that sires with proven ancestry and strong dairy lineage are essential for herd improvement. The author also highlights the economic advantages of culling low-producing cows and using the most productive animals for breeding. The book concludes with a powerful reminder of the profound role that selective breeding plays in not only enhancing the physical characteristics of a herd but also in improving its overall profitability and sustainability.
