“…The difference between all stages in terms of CP ratios was significant (p<0.001). The results of chemical analysis of Phacelia showed that CP content decreased with the growth and maturity of the plant, which is consistent with the results of some previous studies (Soya et al, 1999;Kamalak et al, 2014;Kaplan et al, 2017;Ayaşan et al, 2021). In another study (Geren et al, 2007) on two different Phacelia cultivars, it was observed that the mean values of the ratio CP were lower than the values obtained for all four stages in this study.…”

“…In our study, these values increased in a general trend. The daily gas production values of Phacelia plant for the preflowering stage in this study were very low compared to the values reported for quinoa and wild trefoil (Kaplan et al, 2017;Kamalak et al, 2014Ayaþan et al 2020bAyaşan et al, 2021). In this study, CH 4 concentrations for the first, second, third and fourth stages were 0.93, 5.33, 4.74 and 5.38 mL, respectively, while CH 4 ratios were 3.…”

Backround: This study was carried out to determine the nutritional value and methane production potential of Phacelia tanacetifolia plant in different growth stages in April-May year in the ecological conditions of the province of Adiyaman in Turkey. Methods: Phacelia (Phacelia tanacetifolia) plant samples were collected with four replications in four different stages, pre-flowering, early flowering, mid-flowering and end of flowering (seeding). The nutrients of the feed samples were determined. The gas production was measured after 24 hours of incubation of the forage with rumen fluid. Result: The effect of harvest time on chemical composition was highly significant. In vitro gas production was lowest in stage I. and highest in II. The methane (CH4) lowest production values were found in the 1st stage, whereas the highest value was observed in the 4th stage (seed-binding stage), where the difference was statistically significant. ME was 7.49, 9.54, 8.90 and 8.61 MJ/kg DM respectively and the difference between the stages was statistically significant. It was concluded that Phacelia tanacetifolia, which is known as an important nectar source in the world and in Turkey. It is appropriate to harvest the phacelia plants in the second stage, i.e., at early flowering for higher ME contents and OMD.

“…In forage plants, quality is associated with the contents of nutrients and toxic substances. It is affected many factors such as ecological conditions, plant species and variety, harvest time, and fertilizer (Gülcan et al 2002;Ayasan et al, 2021). Feed quality, that is, the capacity to provide the desired nutrients to ruminant animals, (Adesogan et al, 2006;Newman et al, 2006;Muir et al, 2007) is economically important in selling or purchasing (Schut et al, 2010).…”

The purpose of this study was to compare the chemical composition, metabolizable energy, net energy lactation, total digestible nutrient, in vitro digestion parameters, and relative feed quality of some grass forage plants growing naturally in the meadows and pastures of Erzurum province in Turkey. Orchardgrass (Dactylis glomerata), Variegated brome (Bromus variegatus), and Intermediate wheatgrass (Agropyron intermedium) were used as the research material. In this study, the metabolizable energy (ME) and net energy lactation (NEL) contents of the green grass crops forage plants were determined by in vitro gas production method, and their digestibility parameters and relative feed quality (RFQ) by the neutral detergent fiber (NDF) procedure using an Ankom Daisy incubator. As a result of the study, the differences between the forage plants were found to be statistically significant in terms of chemical composition, metabolizable energy, net energy lactation, true organic matter digestibility (TOMD) and RFQ (P<0.05). While the green intermediate wheatgrass was found to have the highest crude protein (CP) (19.56%), crude fat (CF) (3.06%), dry matter (DM) (9.14%), ME (8.82%), NEL (5.42%), and TOMD (97.75%); the green variegated brome was found to have the highest RFQ (149.79). The green orchardgrass was found to have the highest contents of neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) with 66.23%, 34.14, and 8.52%, respectively. In conclusion, the green grass forage plants examined in this study can be used to eliminate the quality roughage deficit.

“…In ruminant determination of nutritional value of feeds and the effect of various processes including heat treatment is important, also it is important to study the amount of disappearance in the rumen, intestine and the entire gastrointestinal tract, which can be examined using methods such as nylon bags, gas production technique and three-step laboratory method (Ayasan et al, 2021).…”

Due to improving the nutritive value of oilseeds and changing their digestion site in ruminants, processing, including heat treatment, seems necessary. The present research was conducted to evaluate the effect of applying heat processing such as roasting, microwaving and autoclaving on nutritive values; the amount and rate of degradability in rumen, and the disappearance of rapeseed nutrients in rumen, post-rumen and total tract. This evaluation was performed using mobile nylon bags techniques; three-step method of digestion and protein CNCPS fraction. A completely randomized design was used to investigate the effect of applying heat processing, and SAS software was used to analyze the data. The field Emission Scanning Electron Microscope was used to monitored the effect of heat treatment on surface of rapeseed. The application of heat processing in this research (roasting, microwaving and autoclaving) had no significant effect on the chemical composition of rapeseed. The results obtained from mobile nylon bags method and three-step digestion method showed that raw rapeseed has the highest disappearance of DM and CP in rumen and therefore has a significant difference with processed seeds (P<0.05). Also, the disappearance of DM and CP of processed rapeseed in intestines was significantly higher than raw seed (P<0.05), and this was higher than other processing for autoclaved rapeseed. According to the results obtained from CNCPS protein fractionation, applying heat processing altering protein fractionation (P<0.05). Applying microwave processing has created cracks in the surface of the rapeseed wall, and this condition was not observed in the wall surface of other heated seeds. In general, it can be said that in addition to increasing the digestibility of rapeseed in the entire gastrointestinal tract, applying heat processing reduces its degradability in the rumen and has increased the disappearance of nutrients in the intestine, that it can be stated the digestion site is altered from rumen to intestine, which can prevent the loss of protein sources in ruminant feed.
