The objective of this course is to introduce students to the principles of dry matter intake in dairy cattle feeding, and to provide them with the ability to meet nutrient requirements during lactation phases, transition, and dry periods according to international standards. The curriculum covers the interactive relationships between rational feeding and milk composition, reproductive performance, and heat stress. Additionally, calf and heifer rearing strategies, the prevention of metabolic diseases associated with nutritional imbalances through feed management, and the evaluation of TMR quality using the Penn State Particle Size Separator are targeted.
1. Current status of the dairy cattle sector, genetic and environmental factors influencing milk yield, and the role of rational feeding on farm profitability. 2. Physiological and physical factors affecting dry matter intake in dairy cattle, and core theories in the regulation of feed consumption. 3. Nutrient requirements of dairy cattle. 4. Feeding strategies during the transition period, lactation phases, and the dry period, along with the management of metabolic diseases resulting from nutritional imbalances. 5. Interactive relationships between nutritional management and reproductive performance, service period, and milk composition 6.Feeding of calves and heifers, utilization of feed additives, and evaluation of TMR quality.
| Prof. Gürhan KELEŞ |
| 1. | Analyzes the physiological and physical factors influencing dry matter intake in dairy cattle enterprises, and explains the core theories in the regulation of feed consumption. |
| 2. | Evaluates the energy, protein, mineral, and vitamin requirements of dairy cattle across different physiological periods such as lactation, pregnancy, and growth according to international feeding standards. |
| 3. | Manages nutritional strategies during the transition period, lactation phases, and the dry period in dairy cattle; controls metabolic disorders (acidosis, ketosis, hypocalcemia, etc.) associated with nutritional imbalances through feeding practices. |
| 4. | Develops ration modifications against the adverse effects of heat stress on intake and milk yield; evaluates the effects of nutrition on reproductive performance, days open (service period), and milk composition. |
| 5. | Defines the nutrient requirements and target body weight gains suitable for the rumen development characteristics of calves and replacement heifers; analyzes and interprets the physical structure of TMR in mature cattle using the Penn State Particle Size Separator. |
