An attempt was made at identifying the activity of acid phosphatase (AcP) and β-Nacetylhexosaminidase (Hex) in the whole raw milk of cows maintained on ecological farm and over the autumn/winter and spring/summer seasons (AW and SS season, respectively) fed with typical feeding rations. Both enzymes play a crucial role in animals’ metabolism, affect the technological properties of milk and are indicators...
Experiment was conducted with 36 dairy cows (in II-VI lactation), divided as analogues to three groups per 12 weeks (3 weeks before calving to 0 day – day of calving and second period first 70 days of lactation): group I – without glycerin supplement, group II – 300 ml·head-1·day-1 and III – 500 ml·head-1·day-1 supplemented to daily feed ration. All cows were fed two kinds of TMR, according to DLG...
From the second week after calving to the 120th day of lactation a mineral-fat (PMT) supplement was used in feeding high yield cows; group I - 1.1 kg, group II - 0.8 kg daily per animal. In the first four months of lactation, a statistically significant higher daily milk yield was noted from cows from the experiment groups as related to those from the control group (ca. 1.5 kg daily). In the group...
