Abstract: The aim of undertaken studies was to determine an impact of Keton Blend SP-1 supplement (containing both propylene glicol and choline chloride) on milk yield and energy parameters of Holstein-Friesian cows in early lactation. Research was undertaken in 2013 in one of the agro-breeding farms in the Sztum district, Pomeranian voivodeship. Research material consisted of Holstein-Friesian race cows in 2nd lactation. Keton Blend SP-1 supplementation applied to the diet of cows from research group (20 pieces) was used in research. Application of the supplement started on the 15th day of lactation and continued for the next 30 days. During the experiment blood samples were collected 3 times from the jugular vein of each cow, i.e., on 14th day of lactation, after 30 days of supplementation and 30 days after discontinuation. During the experiment condition of cows was assessed by BCS (Body Condition Score) method using the 5-grade scale. Daily milk yield (kg) and content (%) of basic milk components as well as dry weight (%) and urea (%) in the studied periods were also determined. Basing on the undertaken experiment to apply Keton Blend SP-1 as nutritional supplement it is not possible to clearly define its positive impact on the energy balance of dairy cows in an early lactation. Research showed only a slight increase in daily milk yield of supplemented dairy cows with a slight decline in their condition.
