“…It is assumed that the intake of a nutrient is related to the amount of that nutrient in the feed. In the present study, the higher CP intake and higher NDF and ADF intake by sheep fed on OT and NH, respectively, may be a reflection of the chemical composition of the feed more than of the DMI (Abdelraheem et al, 2019); in our research, the DMI tends to be similar between tested herbage. Jafari and Javarsineh (2005) observed a significant positive relationship between digestibility and WSC concentration.…”

“…Hence, the studies concerning OT digestibility, nutrient metabolism and N excretion in urine and feces are still scarce. In our previous publication (Abdelraheem et al, 2019), we compared the nutritive value of native herbage and oat forage in winter (during forage shortage period in QTP). Unlike winter, supplementary feeding in summer is a key way to reduce grazing pressure and maintain the balance between the supply of pasture and the demand for grazing livestock.…”

Satisfying the animals feed demand from the forage supply by grasslands remains a major challenge in the grassland–livestock ecosystem. To provide an alternative forage sources, this study conducted two feeding trials in the summer of 2015 and 2016 to compare the nutritive value, digestibility and nutrients utilization of native pasture (NH) and oat forage (OT) fed to Tibetan sheep (Ovis aries). Twelve Tibetan sheep with a mean body weight of 39.11 ± 3.66 kg in 2015 and 27.97 ± 2.69 kg in 2016 were use in this study. The experiment was 2 (year: 2015 and 2016) by 2 (forage: NH and OT) factorial. Data on proximate analysis, fiber fraction and nutrients digestibility were collected and analyzed using general linear model. However, the crude protein (CP) and water‐soluble carbohydrates contents in OT were higher (P < .001) than those in NH by 7.81–8.93% and 46.40–47.05%, respectively. In contrast, the neutral detergent fiber (NDF) and acid detergent fiber contents were higher (P < .001) in NH by 14.28–15.78% and 15.62–18.00%, respectively. The dry matter digestibility coefficient in OT (0.82 in 2015 and 0.79 in 2016) was significantly higher than that in NH (0.68 in both years). In addition, the OT diet had higher (P < .001) organic matter, NDF and CP digestibilities. Animals fed OT retained significantly more nitrogen (2.66 g/day in 2015 and 1.93 g/day in 2016) than those fed NH (0.96 g/day in 2015 and 0.42 g/day in 2016). The digestible energy and metabolizable energy were higher (P < .001) in OT than in NH. Our data indicated that Tibetan sheep urinary N excretion increased by 0.726 g with increase of 1 g in the nitrogen intake. Conclusively, the OT had higher nutritive value than NH and could therefore use to satisfy livestock demand and reduce the grazing pressure on grasslands.

“…Studies have shown that increasing the ruminal fermentability of high-quality forage fed to ruminants would have the same benefits as feeding concentrate, because it could increase the energy supply from volatile fatty acid (VFA) and protein from microbial protein synthesis ( Broderick et al., 1999 ; Cantalapiedra-Hijar et al., 2009 ; Zhu et al., 2013 ). In addition, numerous studies confirmed that the digestible energy content of forage is largely determined by the digestibility of dry matter (DM) or neutral detergent fiber (NDF) ( Aboagye et al., 2015 ; Abdelraheem et al., 2019 ). Therefore, ensuring the long-term quality of green forage and improving its digestibility have received a great deal of attention in the dairy industry of the world.…”

“…Independent of cultivation practice, the protein content measured in switchgrass forage (5–6%) is substantially greater than the values reported for rice hay [ 52 ], barley ( Hordeum vulgare L., 4.3%) [ 53 ], and wheat (3.5%) [ 54 ], but lacks behind the protein content reported for oats hay by 1–1.8% [ 55 ]. Nevertheless, the digestibility of switchgrass hay, as measured by ADF and NDF values, appears to be greater than that of oats [ 55 ].…”

Nowadays, the lack of cattle feed, particularly green fodder, has become a key limiting factor in the agricultural economy. Switchgrass appears to offer a viable solution to the feed shortage. An improved cultivation practice might be needed to boost switchgrass forage production all season long. This study was conducted to quantify the positive effects of introducing different legume crops (vetch and pea), optimally fertilized, on the production and quality of mixed harvested switchgrass–legumes hay in late spring (May) and switchgrass hay harvested once more in early fall (September). The studied intercropping systems, independently of the legume species used, increased forage productivity (almost threefold), reaching 7.5 t ha−1 and quality characteristics, with protein content almost rising threefold, reaching 12.5%. The aforementioned practice can assist the perennial crop (switchgrass) in providing a high hay production during the early fall harvest, even without fertilization. The overall annual economic benefit for the farmers may be increased by 90–720 € per ha, depending on the prevailing weather conditions. Overall, it may be concluded that the suggested cropping system produces a significantly higher yield of cattle feed compared to traditional monocultures, improving the agricultural economy while reducing the negative effects of modern agriculture on the environment.
