Paperback. Condizione: New. Print on Demand. This book reveals the nutritional requirements of pregnant swine in unprecedented detail, examining the growth of fetuses and their nourishing environment across gestation. The author meticulously measured the chemical composition of the uterus and its contents at different stages of pregnancy, providing a comprehensive understanding of fetal nutrient deposition. Detailed balance experiments conducted on pregnant swine determined the minimum daily requirements for nitrogen, calcium, and phosphorus, offering insights into the complex metabolic processes at play. The book also explores the relationship between fetus weight and litter size, as well as the distribution of nutrients within the fetus. Its findings have significant implications for understanding the nutritional needs of pregnant animals, and contribute to the broader field of reproductive physiology, making it an invaluable resource for researchers and practitioners alike. 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 delves into the utilization of calcium and phosphorus in growing swine. The author investigates the relative effectiveness of various mineral supplements, including bone meal, limestone, and rock phosphate, in promoting growth and bone calcification. The results challenge the long-held belief that complex mineral mixtures are superior to simpler supplements and provide valuable insights into the specific role of different calcium sources. The book also addresses the question of whether swine rations are likely to be deficient in phosphorus, and the author's findings suggest that phosphorus deficiency may not be as common as previously thought. This research is crucial for maximizing swine production efficiency and ensuring adequate nutrition for these animals.
