Paperback. Etat : New. Print on Demand. This book is an account of the author's scientific research into early weaning of dairy calves, beginning in 1933, and their conclusions on the rearing of dairy calves with limited milk. The author describes the experimental successes that began with one male calf in 1933 who thrived on a diet of colostrum and skim milk supplemented with cod liver oil. The author goes on to describe the expansion of this study to include over 100 calves, both male and female, over the following decade. The author describes how they tested the effects of weaning calves at different ages, ranging from 30 to 90 days, and with the addition of supplements to increase nutrient intake, such as flaxseed jelly and grain mixtures. The primary focus of this book is on the nutritional needs of calves and the practical application of this research within the economic constraints of dairy farming. The broad historical context of the book is the development of scientific knowledge about animal nutrition. The thematic depth of the book lies in the author's discussion of the balance between a calf's nutritional needs and the economic realities of dairy farming. The insights gained from this research have changed the way dairy farmers raise calves by demonstrating that calves can be raised with limited milk and without the traditional use of dried milk, dried blood, or other protein supplements of animal origin.
