Crown vetch (Coronilla varia L.) is a widely spread legume species that can be used as a forage crop for herbivores. The crown vetch herbage was ensiled with 0, 4, or 8% of crushed barley grain on a wet basis. The crude protein (CP) and neutral detergent fiber in organic matter (NDFom) contents of crown vetch herbage were higher than those of crown vetch silages (p < .05). The malondialdehyde (MDA) concentrations of herbage and silages with barley grain were lower than that of silage without barley grain (p < .05). The linoleic acid (C18:2) percentage of total fatty acids in forage decreased with the ensiling process (p < .05). The addition of crushed barley grain in the ensiling process of crown vetch herbage preserved the α‐linolenic acid (C18:3) percentage of total fatty acids (p < .05). The crushed barley grain positively affected dry matter (DM) and ammonia‐nitrogen levels, acidity value (pH and lactic, acetic and propionic acids) and in vitro ruminal fermentation values (cumulative gas production, metabolic energy [ME], net energy lactation [NEL] and organic matter digestion [OMd]) of crown vetch silage (p < .05). The concentration of volatile fatty acids (acetic, butyric, propionic, iso‐valeric and iso‐butyric acids) in the in vitro ruminal fermentation fluid was similar in herbage and silages of crown vetch (p > .05). Consequently, crushed barley grain (especially 4% rate) in the ensiling process of crown vetch increased hemicellulose, easily digestible carbohydrates, linoleic acid, α‐linolenic acid in silage and in vitro ruminal digestion parameters, positively affected silage acidity and decreased lipid peroxidation.

“…Reducing ruminal methane emission is vital because of its negative contribution to global warming (IPCC, 2014). While reducing ruminal methane emission, feed digestion in the rumen should not be adversely affected (Kara, 2021; Kara et al, 2018). Although methane production decreased in the FA50MA50 group, in vitro total gas production and other digestive values were also adversely affected.…”

The study aimed to determine the effect of fumaric and maleic acids on the ensiling process. The corn herbage was ensiled without additives (control silage) or with 0.25% fumaric acid (FA25), 0.50% fumaric acid (FA50), 0.25% maleic acid (MA25), 0.50% maleic acid (MA50), FA25 + MA25 (FA25MA25) and FA50 + MA50 (FA50MA50) (treatment silages) as wet basis. The starch contents of FA50 and MA50 silages were lower than the content of the control silage (p < .05). The lactic acid content of the FA50MA50 silage was lower than that of the control silage (p < .05). Percentages of linoleic acid of MA25 and MA50 silages were higher than that of the FA50 silage (p < .05). The in vitro methane production and metabolic energy (ME) value of FA50MA50 silage was lower than that of the control silage (p < .05). The in vitro organic matter digestion (OMD) values of FA25, MA25 and FA50MA50 silages were lower than that of control silage (p < .05). The molarities of acetic (AA), propionic (PA), butyric (BA), isovaleric (IVA), isobutyric (IBA) and total volatile fatty (TVFA) acids of the in vitro ruminal fermentation fluid for the FA50MA50 silage were lower than that of the control silage (p < .05). As a result, the addition of fumaric and maleic acids (0.25% alone and together, or 0.5% alone) in ensiling of corn herbage did not change the quality, acidity (except for propionic, butyric and isobutyric acids) and nutrient contents (except for non-fiber carbohydrates and starch) and in vitro ruminal fermentation values (gas-methane production and organic acids).The combined use of 0.5% fumaric plus 0.5% maleic acid harmed silage quality and in vitro ruminal fermentation values. However, 0.5% maleic acid was partially more effective than those other organic acid additions in preserving linoleic and α-linolenic acids in the silage material.

BackgroundIn ruminants, fibrous feedstuffs must be included in the ration to ensure normal rumen physiology and to prevent the occurrence of rumen‐related metabolic diseases. In addition to being a source of fibrous feedstuffs, they contain energy depending on the level of digestion and protein, minerals, fatty acids, minerals, and secondary compounds.ObjectivesThis study aimed to determine the nutrient matter, fatty acid, mineral and in vitro rumen fermentation values of the pennyroyal (Mentha pulegium L.) plant.MethodsThe pennyroyal plant samples were collected at different phenological stages (vegetative, full flowering, and seed bulking) from the natural meadow. The samples were analysed for core nutrients, condensed tannins, minerals, fatty acids, and in vitro ruminal fermentation parameters.ResultsThe calcium (Ca) and iron (Fe) contents and in vitro ruminal fermentation parameters (total gas production and methane production, organic matter digestion (OMd), and the ammonia‐nitrogen) decreased with increasing phenological stage (p < 0.05). The percentages of linoleic, α‐linolenic, ω‐3, ω‐6 and polyunsaturated fatty (PUFA) acids of the pennyroyal plant linearly increased with the phenological stages (p < 0.05). However, butyric acid (BA) concentration in the in vitro ruminal fermentation fluid in the full flowering stage was lower than that of other stages (p < 0.05).ConclusionsPennyroyal plant is a functional plant in terms of high values of ether extract (EE), α‐linolenic acid, linoleic acid, ∑ω‐3 fatty acids, Ca, Fe and Zn contents. For this plant to be used as animal feed, the stage when it has the highest values for Ca, Mg, S and Zn minerals and in vitro OMd were vegetative and full flowering. The stage with good potential as animal feed for ∑ω‐3 and ∑ω‐6 fatty acids and core nutrients (CP and EE) is the seed bulking stage.
