Effect of extruded rapeseed cake and extruded full-fat soybean in cows’ diet on casein fractions and amino acid profile of milk

Original language description

The aim of the study was to determine the effect of two protein supplements, i. e. extruded rapeseed cake and extruded full-fat soybean in cows’ diet on casein fractions and amino acid profile of milk. The experiment was carried out on four lactating Holstein cows as replicated Latin square in a double reversal design. The experiment was divided into four periods of 42 days consisting of a 21-day preliminary period and a 21-day experimental period. Cows were divided into two groups. The control group (R) was fed a diet based on extruded rapeseed cake while the experimental group (S) received a diet containing extruded full-fat soybeans. The dry matter intake did not differ between groups (P>0.05). Milk yield and yields expressed in 4% FCM and ECM were higher in S compared to R (P<0.01). The concentration of milk protein was higher in R than in S (P<0.05) while concentration of casein was similar in both groups being 2.53 and 2.55 g/100g in R and S, respectively (P>0.05). Concentration of kappa-casein was lower in R in comparison to S (P<0.05) and concentration of beta-casein tended to increase in the R group (P=0.089). Content of alpha-casein did not differ significantly (P>0.05). The concentration of individual amino acids in milk as well as the sum of essential and non-essential amino acids in both groups reached almost the same values (P>0.05).
