The purpose of the study was to investigate the influence of production year on the milk yield per standard 120-day milking period of sheep from the Bulgarian Dairy Synthetic population in the flock of Agricultural Institute-Shumen. Milk productivity data of 2193 sheep of different ages for six production years, were analysed. For the individual years, the following were determined: duration of lactation and milking period, milk yield per milking period (TMM), average daily milk yield per milking period (ADMYmilking period) and milk yield per 120-day standard milking period (TMM120). The influence of the production year on milk yield per standard 120-day milking period was determined by the ANOVA model for one-way analysis of variance. The total milk productivity for the standard 120-day milking period of sheep in the individual production years was within 94.798-115.541 l, with the determined differences having a high degree of significance (Р≤0.001). A highly significant effect of the production year factor on the milk yield per standard 120-day milking period per consecutive lactation was established.
