Using invasive plants as non-conventional forage in livestock production can contribute to meeting climate change targets and provide a competitive advantage in a global market. This study evaluated the nutritional potential of several non-conventional plants: Pennisetum setaceum, Ricinus communis, Arundo donax, Acacia melanoxylon, Opuntia ficus-indica, Agave americana, Pittosporum undulatum, and Hedychium gardnerianum. Chemical composition, in vitro digestibility, gas production, and energy estimates were determined. Opuntia showed the lowest DM value (6.65%), while the highest was found for Acacia (39.43%). Ricinus recorded the highest levels of CP (23.56% DM), RFV (273.86), and in vitro gas production at 24 h (43.49 mL/200 mg DM). The highest NDF (80.39% DM), HEM (39.03% DM), and CEL (36.81% DM) values were observed for Pennisetum. Agave produced the highest amount of gas from the start to the end of incubation (22.68 to 48.99 mL/200 mg DM), while Acacia produced the least (3.83 to 14.78 mL/200 mg DM). The highest ME (8.72 MJ/kg DM) and NEL (5.06 MJ/kg DM) estimates were obtained for Agave. Correlations between the chemical compositions and feed quality indices of the plants were observed, showing strong negative correlations between ADF and DMD, OMD, and DMI (r > 0.86, p < 0.01). We can conclude that all these non-conventional plants have potential as an alternative feed for ruminants when there are fodder shortages.

This study aimed to elucidate the effects of various chemical treatments on the in vitro dry matter digestibility (IVDMD) and concomitant feed value of dried grape pomace (DGP). Sun-dried grape pomace, derived from grapes processed in Denizli, Türkiye province was used in the experiment. One control group and three treatment groups were established, each with eight replicates. The first, second and third experimental groups were treated with 1.5% ammonia (NH3), 3% urea (CH4N2O) and 3% sodium hydroxide (3%) (NaOH), respectively. The dry matter content was set at 50% for all groups. The control group received no additional chemicals. All groups were kept in airtight, closed plastic bags at room temperature for one week. Adding NH3 and CH4N2O significantly improved crude protein levels (24.45 and 19.84%, respectively) and in vitro protein degradability (59.84 and 65.69%, respectively) in the experimental groups (p

The aim of this study is to evaluate the effects of treatment with sodium hydroxide on the nutritional value of banana (Musa acuminata) trees to see if they can be used as a source of fibre for ruminants since there is large banana production and consequently some waste. The samples were collected and dried in an oven with a controlled air flow. They were then sprinkled with a sodium hydroxide solution (2, 4, 6 and 8% of dry matter) and placed in a suitable container. The chemical properties were analysed. The results show that sodium hydroxide treatment leads to a significant decrease in neutral fibre and acid lignin contents in both leaves and pseudostems. A significant (p < 0.05) increase was observed in ash, and digestibility values were lower in leaves, confirming the values for neutral detergent fibres. The total amount of gas produced was measured after 4, 8, 12, 24, 48, 72 and 96 h of incubation. The results showed that the gas production in the leaves was lower in all treatments compared to the pseudostem, which was consistent with the digestibility results. Analysis of the results showed that the best NaOH concentration to improve the nutritional value of M. acuminata was 6 and 8%.
