Features: This book is mainly divided into six chapters:
Chapter 1 takes each beverage raw material as the description object, organizes its feed description and all nutrient indicators, andly places them in a standardized data table for easy reference and use by readers. All generated data tables are derived from (Nutrient Requirements of Dairy Cattle) (2001).
Chapter 2 adopts a data exploration approach, classifying and managing the different attribute data of feed, i.e., nutrient indicators, in separate tables, facilitating the comparison of the same (category) nutrient targets or attribute data across different feeds. All data are converted to feeding status values.
Chapter 3 compiles and collects the tables of dairy cow nutrient requirements published in 《》, and the accurate translation of the dairy cow requirement tables has been permitted by the National Academy of Sciences Press. The average values provided in the tables should be used in conjunction with computer models for dynamic simulation to accurately predict dairy cow nutrient requirements.
Chapter 4 primarily collects several corresponding research reports. In the practice of utilizing the developed software system and applying the new dairy cow standard system to optimize dairy cow ration formulations, it was found that the new system's dairy cow ration formulation design has its own certain patterns, which are not only different from the formulation design of monogastric animals (total concentration formulation design) but also fundamentally distinct from the digestible crude protein system that China had previously implemented.
Chapter 5 utilizes the dairy cow ration formulation system studied by us. Under the premise of selecting a set of feed raw material combinations, certain principles are pre-agreed during the optimization process through repeated screening, resulting in typical lactating dairy cow formulations tailored to different body types, daily milk yields, milk fat rates, and milk true protein levels. Additionally, using the mathematical models recommended in 《》, the flow of various essential amino acids entering the duodenum after feeding each ration is estimated, including the total amino acid flow and the available amino acid flow.
The sixth chapter of this book introduces the basic interface of the "High-Yield Dairy Cow Full-Process Rearing, Nutritional Knowledge Consultation, and Ration Optimization Decision Intelligent System (International Edition)" for reference by the system's users.
