V. Lykhach, S. Kramarenko, P. Shebanin. The use of entropy-information analysis to assess the reproductive qualities of crossbred sows
\nThe possibility of using entropy and information analysis (EIA) in various fields of biological science has been noted by many authors. However, most of these works showed examples of the application of EIA in the study of discrete (qualitative) characteristics. Modification of EIA for quantitative traits using the integrated density estimates of the distribution of standardized values, gave the opportunity to expand the application of this method for the evaluation of various quantitative indicators of efficiency of agricultural animals. For carrying out entropy and information analysis using a modification for quantitative traits were used data on age-related dynamics of the reproductive qualities of two-breed sows: large white (LW) and Ukrainian meat (UM) in combination with boars of Landrace (L). The reproductive traits of sows was measured in terms of total number of born piglets (TNB), number of born alive piglets (NBA) and number of weaned piglets (NW). The animals belonged to the LLC “Tavriysky pigs”, Kherson region. Were used for research data on productivity according to the results of the first seven farrowing eighty sows each of the genotypes. It is proved that the degree of determinacy reproductive characteristics, including age-related dynamics, influenced by the breed sows. It is established that the highest level of order is characterized by the number of piglets at weaning (NW). Therefore, this indicator should be used as a reference when assessing the reproductive characteristics of sows.
