“…Annual forage species might meet this instant need (Aydın et al, 2015;Kazemi and Valizadeh, 2019;Uzun and Ocak, 2019), but annual species without autumn to spring cycles are not essential components of sustainable grazing systems (Frost et al, 2008;Abbaye et al, 2009;Uzun and Ocak, 2019). Based on our RFV and RFQ results, weeds had better values than desirable legumes (Lotus corniculatus, Medicago sativa, Trifolium pratense, Trifolium repens), grasses (Dactylis glomerata, Festuca ovina, Lolium perenne) and other families (Cichorium intybus and Sanguisorba minör) collected from same rangelands (Aydın et al, 2022). Similarly, perennial weeds in rangelands have had equal or superior forage quality compared with some desirable grasses and legumes species (Frost et al, 2008;Abaye et al, 2009;Kazemi and Valizadeh, 2019).…”

“…Digestible DM (DDM), DM intake (DMI), metabolizable energy (ME), net energy lactation (NEL), estimated net energy (ENE), total digestible nutrients (TDN), relative feed value (RFV) and relative forage quality (RFQ) of weeds were calculated (Undersander et al, 2010;Pflueger et al, 2020;Aydın et al, 2022). The NEL and TNE values were expressed converting to MJ/kg DM.…”

In this study, common weed species (Anthemis sp., Anthemis tinctoria L., Pilosella hoppeana Schultes, Doranicum orientale Hoffm, Muscari neglectum Guss. ex Ten., Ornithogalum armeniacum Baker, Ornithogalum narbonense L., Ornithogalum wiedemannii Boiss., Anchusa azurea Miller, Echium plantagineum L., Echium vulgare L., Ajuga orientalis L., Stachys germenica L., Juncus sp., Anacamptis pyramidalis L., Ophrys apifera Huds., Carex panicea L., Ranunculus sp., Hypericum perforatum L., Primula elatior L. Hill., and Galium rotundifolium L.) of the rangelands of Akdağ mountains, Samsun were evaluated by principal component analysis (PCA) and cluster analysis (CA). These species were collected at least three times in two consecutive years. The proximate nutrients (organic matter, ash, crude protein, ether extract, neutral and acid detergent fibre, non-fibrous carbohydrate and hemicellulose), neutral detergent fibre properties (nitrogen-free neutral detergent fibre and in vitro neutral detergent fibre digestibility), and forage quality indicators (digestible dry matter, dry matter intake, metabolizable energy, net energy lactation, estimated net energy, total digestible nutrients, relative feed value, and relative forage quality) were assessed by chemical analysis and empirical equations. There were significant variations in the nutritional dynamics among the weed species. The PCA results demonstrated a relationship between the dietary dynamics assessed. Component 1 (65.5%) and component 2 (14.5%) described 80.0% of the total variation, with eigenvalues of 11.788 and 2.609 in the weed species, respectively. The loadings plot of components shows that most forage quality indicators were distributed to Quadrant 1 and Quadrant 4. Three clusters are observed from the CA for the weeds with significant linkage distance, indicating relatively high independence for each cluster. Due to high variation in their nutritional dynamics, the weed species (P. elatior, O. wiedemannii, O. narbonense, and G. rotundifolium) were more similar on component 1 ordination and in Cluster 1 of the dendrogram. In conclusion, our results suggest that the highlighted species have significant potential for grazing livestock as forages and could fulfilling the possible forage gap in the grazing system.

High-quality forage in livestock feeding will significantly enhance both the yield and quality of animal products. In this respect, it is crucial to know in advance the forage quality traits to make the right choice. Accordingly, the research was fulfilled to determine forage crude protein content and the other forage quality traits in some annual plant species from different families. According to the variance analysis, it was determined that there were statistically highly significant (P<0.01) differences between the species in terms of all the of the examined traits, and the examined traits were found to be in the following ranges; dry matter content (DMC) 15.67–26.97%, crude protein (CP) content 11.93–24.11%, acid detergent fiber (ADF) content 29.54–46.488%, neutral detergent fiber (NDF) content 38.30–62.89%, digestible dry matter (DDM) contents 52.33–65.89%, dry matter intake (DMI) 1.91–3.14%, metabolizable energy (ME) 7.67–10.27 MJ kg-1 DM, relative feed value (RFV) 77.5–160.2, calcium (Ca) content 6.72–18.72 g kg-1 DM, phosphorus (P) contents varied from 3.59–5.35 g kg-1 DM, magnesium (Mg) content 2.25–4.35 g kg-1 DM, potassium (K) content 28.58– 44.40 g kg-1 DM, Ca:P ratio 1.50–4.91 and K/(Ca+Mg) (tetany) ratio 1.34–3.94. Additionally, as a result of comparing the research results with the literature knowledge, it was understood that the Ca, P, Mg and K contents of the examined species were sufficient for the livestock needs. However, due to relatively higher-level K content and lower Ca and Mg contents, the tetany (K/(Ca+Mg) ratios of grasses species, Lolium multiflorum and Triticum aestivum, were found to be over the critical value (2.2) for grass tetany illness. Thus, when livestock intensively feed forages of the grass species, risk of getting grass tetany disease would be higher than the other species. On the other hand, the biplot analysis showed that there was a positive and significant relationship between CP, DDM, DMI, ME and RFV traits, and legume family species, Lathyrus sativus, Trifolium nigrescens and Pisum sativum spp. arvense came to fore in terms of these five traits. These legume species with having higher level the most important forage quality traits, their forage quality was found quite better than the other species.
