On day 0 (15-ene-2021), the first sample was taken and sent to the laboratory for bromatological analysis, obtaining an FDN of 49.6, the following sample of the fooder mixture was sent 30 days after the re-growth (día 14-feb-2021) for another bromatological analysis obtaining a FDN of 44.00 with a thermal sum of 389.5 °C and it was culminated with the collection and then the third sample was sent to the next 10 days (24-feb-2021) for analysis with a FDN of 47.6 with a thermal sum of 434.5°C.For this research work 9 cows were used.3 in the first third of lactation, 3 in the second third of lactation, and 3 in the third of lactation,. Weights were taken from them, a record of daily milk production was kept, and blood samples were taken and sent to the BUN and in urine for ketone body analysis With the new grazing management, production increased from 13.3 lts / day to 16 lts / day in average cow / day. |
