Research on the Assessment and Quality Control of Maize Silage, Produced and used in the Research-Development Station for Cattle Breeding Dancu, Iași
Abstract
The objective of this research was to observe the quality of the corn silage obtained within SCDCB Dancu, Iași at 2, 4, 6 and 8 months after silage process. The maize was sown at a distance between rows of 70 cm, its fertilization being carried out according to the soil characteristics, using 150 kg / ha NPK (16-16-16). 110-120 days after sowing, when the plants have shown the optimal stage of harvesting. In conducting this study, in order to determine the quality of corn silage, the NIR Analyzer, type Perten DA 7200 was used. The dry matter had a slight upward trend, the observed values being between 37.22% and 37.34%. The crude protein showed small variations between analyzes, the observed values being between 6.6 and 6.7%. In the present study, the values recorded for NDF ranged between 47.25 and 48.10% and the level of ADF showed values between 19.05 and 19.30%, the variations from one analysis to another being insignificant. Regarding ash, the minimum value obtained was 5.4% in the first analysis and 5.5% in the last analysis. Based on the results obtained, it can be concluded that the analyzed corn silage has optimal qualities for its use in animal feed.
