Body size and conformation traits of present-day Zemaitukai horse (ZH) were found corresponding or similar to those of the ancient type, showing that many valuable characteristics of the breed are retained. Mares' milk yield and composition were evaluated, as well as development of foals based on body dimensions. Genetic variation, genetic structure as well as relationship between the lines and families of ZH were studied using blood typing and electrophoretic analysis of serum proteins. Gene frequencies are presented at six blood groups and five protein loci. The genetic diversity within blood groups and serum proteins in ZH kept in a closed population showed that out of eleven gentic systems examined, six were polymorphic. The distribution of allele frequencies varied between the lines and families
