“…Forage nutritive value is determined by nutrient composition, particularly NFC, NDF, ADF and CP, as reported by Lyons et al (2019) and Wahyono et al (2019). Non-fibre carbohydrate includes rapidly fermentable carbohydrates (starch and soluble sugars) (Kondo et al, 2015) and is calculated through a formula that uses ash, EE, CP and NDF (Table 2) (Ayaşan et al, 2020b).…”

The objective of this study was to evaluate the yield, nutrient profile and in vitro digestibility of new BMR mutant lines of sorghum in Indonesia. These mutant lines were GH2.1, GH2.2, GH2.3, GH4.1, GH4.2, GH4.3 and GH4.4. One sorghum mutant line (CTY) and two national sorghum varieties (Super 1 and Bioguma) were also evaluated as controls. In vitro digestibility and rumen fermentation were measured using Ankom Daisy Fermenter and Hohenheim gas test methods, respectively. In vitro measurement consisted of ten treatments with five replications following a completely randomized design. The highest stem sugar content was found in Bioguma (11.22%) and GH4.4 (9.32%) (p<0.05). The Bioguma variety and the GH2.3 mutant line had a higher number of stem segments and fresh forage yield than the Super 1 variety (p<0.05). A greater concentration of crude protein (CP) was observed for the GH.2.1, GH2.2, GH2.3 and GH4.1 lines (p<0.05). The GH2.3 mutant line had the lowest acid detergent lignin (ADL) content (p<0.05), while Bioguma had the highest level of non-fibre carbohydrate (NFC) compounds (p<0.05). The highest relative feed value (RFV) was observed for the GH2.3 line (p<0.05). Furthermore, GH4.2 and GH2.3 had greater in vitro true digestibility (IVTD) (p<0.05) but were not significantly different from Bioguma. Regarding yield characteristics, nutrient composition and in vitro digestibility values, the highest values were found in the Bioguma variety and the GH2.3 mutant line. Except for n-valerate (nC5), significant differences in all rumen fermentation parameters were observed among sorghum cultivars (p<0.05). Regarding the interrelationship between parameters, we found a medium correlation of DMD with the ADL and cellulose content of sorghum forage (R 2 = -0.489 and R 2 = -0.674, respectively). Based on these findings, the GH2.3 BMR mutant line should be further developed as forage sorghum.

“…Santos et al (2018) demonstrate the production of biosurfactant from Yarrowia lipolytica IMUFRJ 50682 using tiger nut fiber and corn steep liquor as carbon and nitrogen sources. Ayaşan et al (2021) recommended the use of tigernut as a cheap energy source for ruminants based on its fat and carbohydrate values. Fiber waste from tigernut processing can be used in the development of eco-friendly materials with low thermal conductivity to be used as lowcost insulating materials (Okorie et al, 2020).…”

There is a need to explore the nutritional and medicinal potentials of underutilized crops such as tigernut. Most conventional foods that are rich and balanced are scarce and expensive, and cannot be afforded by consumers in developing countries. Promoting tigernut consumption will play an imperative role in the health, nutrition, and economy of many developing countries. This review was intended to provide an overview on the nutritional and nutraceutical properties of various tigernut products. Also to provide information on the effects of various processing operations on the nutritional and functional properties of various tigernut products. Tigernut is rich in essential nutrients, numerous bioactive compounds with proven health benefits were found in all tigernut cultivars. Genetic variations, environmental and growing conditions make the yellow, brown, and black cultivars of tigernut to have different physicochemical, phytochemicals and functional properties. Tigernut and its products are recommended in the production of bakery goods and complementary foods. Tigernut extracts are potential candidates for the production of nutraceutical diets and drugs. Compounds with anti-inflammatory, antioxidant, anticancer, antidiabetic, antihypertensive, anti-obesity, antimicrobial and antiseptic properties were found in tigernut. The oil can be used in cooking and frying, the oil is rich in polyunsaturated fatty acids, phytosterols, and tocopherols. The fatty acids composition of the oil is affected by the extraction methods. In addition to industrial applications, wastes and by-products from tigernut processing can also be used as food and feed ingredients.

“…To determine the in vitro feed degradability, ruminal fluid, serum tubes, and experimental treatments were prepared exactly the same as the gas production procedure (Ayasan et al, 2020). The difference was that there were three replications for each treatment, tubes were immediately removed from the incubator after 2, 4, 8, 12, 24, 48m and 72 h of incubation, and transferred to a freezer at -21 °C to prevent further degradation.…”

The effect of using black and green tea waste extracts on the diet nutritional value was investigated with three methods of in vitro degradability, gas production, and McNiven’s enzymatic digestion in the present experiment. Total phenolic compounds and total tannin for green tea extract were 20.3% and 14.8% of dry matter (DM), respectively, and for black tea were 18.7% and 12.7% of dry matter, respectively. The addition of green and black tea waste extracts reduced both gas production during incubation hours and dry matter degradability (DMD) in the diet (p < 0.05). A significantly reduced ruminal dry matter disappearance (p < 0.05) and a significantly increased post-ruminal dry matter disappearance (p < 0.05) were observed by adding black and green tea waste extracts. According to the results, the dry matter disappearance throughout the gastrointestinal tract was not significantly different between treatments. It can generally be concluded that the addition of phenolic compounds can be used depending on the nutritional strategy, such as reducing ruminal degradability and increasing rumen nutrient escape.
