Abstrakt:


The purpose of this experiment was to study the effect of adding mixtures of extruded rapeseeds and faba beans to dairy cows’ rations on milk production and ruminal parameters An experiment was carried out on 75 Holsteinizated Lithuanian Black-and-White dairy cows divided into 3 groups. All cows were fed the same basal balanced diet, but the difference between the treatment was in the adding of extruded rapeseed 30% and extruded faba beans 70% mixture (Trial group – T-1) and extruded rapeseed 70% and extruded faba beans 30% mixture (Trial group – T-2) while the Control group (C-0) was fed the basal diet only. Comparing the beginning and the end of the experiment, total milk yield (P<0.05), content of fat (P<0.05) and protein (P<0.05) increased in both groups fed extruded products. The difference in the lactose content in milk was statistically significant (P<0.05) at the end of the experiment between groups T-1 and T-2 relative to C-0. The total content of saturated, monounsaturated and polyunsaturated fatty acids was affected by the treatment (P<0.05). The content of Palmitic acid and Oleic acid was increasing during the whole experiment in all the groups (P<0.05). The mixtures of extruded rapeseeds and faba beans did not have significant influence on the rumen fluid parameters or on in vitro digestion (P>0.05).
