Method for zoology-and-hygienic prediction of the performance level of the first litter gilts and suckling piglets obtained from them according to the sows’ body defenses and indicators of their hematological profile
It became possible to use software in various areas of biology along with development of High Technology Park in Belarus. Information technologies have been used in zoology engineering in the last few years primarily in selection and breeding work. The aim of research is to develop method for computer zoology-and-hygienic prediction of the performance level of the first litter gilts and suckling piglets obtained from them according to the sows’ body defenses and indicators of their hematological profile. The paper presents curvilinear mathematical models developed based on hematologic profile of the first litter gilts with blood samples obtained from on day 3-4 after piglets birth, allowing to simulate numerical values of sows multiple pregnancy rate, average daily weight gain of piglets and their safety in the first three weeks of life, based on change in morphological, biochemical and immunological blood indices. It has been determined that the positive correlation between hematological parameters of the first litter gilts with the performance indicators are mainly of the humoral defense factors; separate indicators of lipid and carbohydrate metabolism; protein fractions; indicators of protein and pigment metabolism; serum enzymes; separate macro and trace elements. Thus, the computer program allows to predict the sows’ multiple pregnancy rate, average daily weight gain and safety of suckling piglets according to the available parameters of sows’ blood.
