Sažetak
An intensive production and on-going fodder plants yield, on family farms in lowland of Croatia, enable green fodder, hay, haylage as well as part of the fodder plant concentrates and hay-grass mixture production. This will ensure daily milk production of 15 L (4 % milk fat) from 10 cows. These results are obtained with on-going fodder plant blends, from winter as well as from additional and stubble field sowing. In this way better soil and sun energy, required for dry matter formation - recoverable energy source yields are obtained. The obtained dry matter yield, from the fodder plant blends, is in a range from 13.27 to 25.11 t/ha. Digestible row proteins yield is from 1.311 to 2.507 kg/ha, which is sufficient for 1.030-1.928 meals preparation. The energy (SJ) obtained from fodder plant blends, is in the range from 10.59 to 12.56 t/ha sufficient for 1.356-1.608 meals preparation. The required acreage under winter, spring and additional crops, needed for green fodder, haylage and part of the concentrates, is 2.15 ha. In order to ensure hay and part of green fodder needs, hay-grass acreage of 1.18 ha is required. Total acreage, under fodder plant blends and DTS, required for green fodder, hay, and haylage is 40 %. Daily milk production of 15 L (4 % milk fat), from 10 cows, requires com grain acreage of 3.33 ha.
