TY - JOUR ID - TI - EFFECT OF LEVEL OF DRY MATTER AND SOURCE OF SOLUBLE CARBOHYDRATE ON CHEMICAL COMPOSITION OF CORN STOVER SILAGE AU - Mohammed S. kareem1 and Ali A. Saeed2 PY - 2021 VL - 13 IS - 4 SP - 53 EP - 62 JO - Euphrates Journal of Agricultural Science مجلة الفرات للعلوم الزراعية SN - 20723857 AB - The study was conducted in the nutrition laboratory belongs to the Animal Production Department - College of Agriculture/Al-Qasim Green University to investigate the effect of the level of dry matter (DM) of yellow corn stover (YCS), 25, 30, 35 and 40% and the soluble carbohydrates sources (SCS), cane molasses (C-M), date molasses (D-M) and corn flour (C-F) on the chemical composition of produced silage. The results showed that the increase in the level of DM of those materials led to a significant increase (P<0.01) in the DM and ash contents of silage samples produced, while its crude protein (CP) content was decreased (P<0.01) especially in the samples made with a level of 35% DM in which this content was decreased to 5.86%. The percentages of cell wall components were also decreased with the increasing of the DM level, samples of silage made with the levels of 35 and 40% DM were characterized by the lower (P<0.01) content of the neutral detergent fiber (NDF) of 63.64 and 64.71% respectively. The lower (P<0.01) content of the acid detergent fiber extract (ADF, 33.33%) was found in samples made with a level of 35% DM. While the higher (P<0.01) content of hemicellulose (33.20%) was associated with the samples made with a level of 25% DM. With regard to the effect of the SCS, the results showed that a higher (P<0.01) DM content was associated with the silage samples made by the addition of C-F, while the CP content was significantly (P<0.01) increased to 6.25 and 6.34% in the samples made by the addition of C-M and C-F respectively. It was also observed that the addition of C-M and D-M led to a significant decrease (P<0.01) in the NDF, ADF and hemicellulose contents. While the addition of C-F led to a significant decrease (P<0.01) in the content of lignin (ADL) to 17.11% and cellulose to 11.17%.
