MARIUS GHEORGHE DOLIS, CRISTINA SIMEANU, ALEXANDRU USTUROI, DANIEL SIMEANU RESEARCH REGARDING CHEMICAL COMPOSITION AND THE DIGESTIBILITY OF THE MULBERRY LEAVES FROM EFORIE VARIETY
During the growth of silkworm larvae study, also was done a research which aimed to determine the chemical composition and the digestibility of mulberry leaves from a Romanian variety, Eforie. The results showed that advancing in the vegetation stage at the same time with different periods of the silkworm larvae’s growth, the mulberry leaves experience an aging process being noticed through its quality decreasing from chemical composition point of view. So, for example, the CP which was in average 20.98±0.670% (from DM), decreased during the study with 3.11%; while the CF had an average of 17.91±0.434%, (from DM) increased with 2.29%. Accordingly, with this, the majority of nutrients from mulberry leaves, excepting cellulose, had an increasing of digestibility with 33.94%. It was noticed a continuous digestibility decreasing during the growth period for the CP with 22.79% and with 33.53% for NFE. The nutrients digestibility from the leaves registered a value of 59.20%.
