Opis:: The aim of this study was to determine the effect of various additives (straw, grass, molasses, dried sugar beet pulp – pellets, inoculant, organic acids) on the quality and fermentation profile of Virginia fanpetals (Sida hermaphrodita L.) silage. Silage samples were assayed for the content of dry matter – DM, crude ash, crude protein – CP, water soluble carbohydrates – WSC, neutral detergent fiber – NDF, acid detergent fiber – ADF and acid detergent lignin – ADL as well as pH and the concentrations of ammonia nitrogen, lactic acid, acetic acid and butyric acid. Silage quality was evaluated according to the DLG Key. Apparent digestibility was determined in sheep, and the digestibility coefficients of DM, CP, NDF, organic matter – OM and digestible OM were calculated. The tested additives increased DM, decreased ADL content (P≤0.01), and reduced WSC utilization (P≤0.05, P≤0.01) in silages. Only sugar beet pulp decreased the content of NDF and ADF (P≤0.01). All silages had similar pH values (4.01 - 4.10). The analyzed silages were characterized by intense lactic acid fermentation, which was inhibited only by the grass additive (P≤0.01). All additives suppressed acetic acid fermentation (P≤0.05, P≤0.01). Grass and sugar beet pulp significantly decreased the concentration of butyric acid (P≤0.01). The addition of grass decreased CP digestibility (from 92.1% in the control silage to 89.3%), whereas the addition of a bacterial inoculant (P≤0.01) and a blend of organic acids (P≤0.05) increased CP digestibility to 93.8% and 92.8%, respectively. The addition of grass and sugar beet pulp increased the coefficient of NDF digestibility by 6 percentage points relative to 60.9% in the control silage. The addition of the inoculant and organic acids decreased NDF digestibility to 56.0% and 50.5%, respectively. Dried sugar beet pulp was the most effective additive, which positively affected the chemical composition, fermentation profile and apparent digestibility of Sida silage.

Opis:: Sida hermaphrodita as a crop plant could be used as raw material for the production of forage. The aim of this study was to evaluate the overall nutritional value of fresh and ensiled biomass of Sida hermaphrodita, harvested in the bud formation stage. The chemical and amino acid composition, fatty acid profile, concentrations of minerals and polyphenols of herbage and silage were determined. Additionally fermentation products were assessed in silage. Herbage contained crude protein (CP) of 182 g kg-1 dry matter (DM), neutral detergent fiber (NDF) of 375 g kg-1 DM and lignin content in NDF (L/NDF) was 8.88. Nitrogen fractions changed as a result of ensiling (P<0.010), non-protein nitrogen (NPN) from 274 g kg-1 total nitrogen (TN) in herbage to 683 g kg-1 TN in silage, and neutral detergent-insoluble nitrogen (NDIN) from 74.6 g kg-1 TN in herbage to 79.5 g kg-1 TN in silage. Silage was characterized by intensive lactic fermentation (114 g kg-1 DM) and pH of 4.30. It contained CP of 176 g kg-1 DM, NDF of 378 g kg-1 DM, and L/NDF (11.3) was higher than in the herbage. The CP of Sida hermaphrodita silage had a high content of essential amino acids (AAs) Lys, Thr, Val, Leu and Phe (3.98, 4.19, 4.55, 7.14 and 4.00 g 100 g-1 CP, respectively). Sida hermaphrodita silage was characterized by the highest K (6.262 g kg-1DM) content among macronutrients, and the highest content of Fe (40.88 mg kg-1 DM) and Mn (33.01 mg kg-1 DM) among micronutrients. Polyunsaturated fatty acids (PUFAs) predominated in the ether extract herbage and silage, and their proportion was three-fold and seven-fold higher than the proportion of monounsaturated fatty acids (MUFAs), respectively. Herbage had high quercetin content (652 µg g-1 DM), which decreased by 45% during the ensiling. Changes in the chemical composition suggest that this crop plant can be preserved by ensiling. The results of this study indicate that Sida hermaphrodita can be used for producing high-quality silage for ruminants.
