Pig Genetic Breeding Management, Systems Analysis And Design,

Based on investigating status quo of heredity breeding and analyzing record of breeding, the author researched such theory of heredity breeding as growth curve, biostatistics, heredity parameter estimated, breeding value estimated.Using Sybase to manage the data information, design with visual programming language PowerBuilder and Object Oriented Programming Method (OOPM), established a software system which provide decision-making sustain information达式for heredity breeding, producing and administering.In this system, the author mostly completed forecasting the breeding value and adjusting feeding method based on analyzing growth cun}e ; design feeding prescription W th fuzzy linear programming; calculating the breeding value with BLUP method and increase the veracity of breeding value. Another, completed arithmetic design of biostatistics, heredity parameter, breeding value;making use of Sybase in heredity breeding analysis system which made base for breeding analysis theoy networkDesigning rag system with OOPM, it both decreases the number of code and makes all system credible, effective. structure clarity, be prone to maintenance and extend.
