Graphical and mathematical modeling of five-phase stress-free technology of reproduction, rearing and fattening pigs

The article presents an analysis of pork production problems, ways to improve the production. Based on the analysis of methods and technologies for pigs in small pig farms found that the most promising technologies are the stress-free methods of reproduction, rearing and fattening of pigs. The use of stress-free technology of reproduction, rearing and fattening pigs allows to limit or eliminate the effect of stress on the pigs, caused by forced displacements and rearrangements between the phases of the process. This allows for better productivity of the animals and thus shorten the duration of growing pigs to marketable weight. Provided a detailed analysis and describes the requirements for the five-phase stress-free technology of reproduction, rearing and fattening of pigs. Based on the established structural modeling scheme five-phase stress-free technologies have been developed graphical models of growth and weight gain of pigs. Received graphical model allowed to define mathematical models of growth and weight gain of pigs, in the form of polynomial functions of the 3rd and 2nd order, respectively. A brief description of the comprehensive mechanization and experience in the design of the object implementation five-phase stress-free technology for pigs - pig for reproduction, rearing and fattening 500 pigs per year.
