Proximate composition, amino acid profile and some anti-nutrients of Tithonia diversifolia cut at two different times

Abstract

The experiment assessed the proximate and amino acid compositions, metabolizable energy and antinutrient constituents of Tithonia diversifolia leaf meal (TDLM) harvested separately in the months of May and September, respectively using standard laboratory methods. The crude protein (20.5±0.1%), crude fibre (18.8±0.01%) and ash (14±0.1%) significantly (p˂0.05) increased in TDLM for September cutting than that of May (18.05±0.1%, 11.17±0.3% and 13.01±0.1%, respectively). All the anti-nutrient factors (ANFs), namely, oxalate, phenols, phytin, phytin P, saponins and tannins except alkaloids and flavonoids were significantly (p˂0.05) affected by the cutting time of the plant leaf. The ANFs contents in May cutting were oxalate (1.88±0.1 mg/100 g), phenols (0.31±0.01 mg/100 g), phytin (77.3±0.1 mg/100 g), phytin P (21.8±0.1 mg/100 g), saponins (21.8±0.1 mg/100 g) and tannins (0.5±0.01 mg/100 g). The metabolisable energy (ME) for May cutting of TDLM was 2908.27 kcal/kg while that of September was 2565.18 kcal/kg. Glutamic acid had the highest value of 10.94±0.02 mg crude protein among the determined amino acids in TDLM whereas cystine was the lowest (0.94±0.01 mg crude protein for both May and September cuttings. TDLM is limiting in methionine with a chemical score of 30 in both cuttings. Proximate composition of TDLM was higher for September cutting than May and could be used as vegetable protein source.

Quality evaluation of tithonia (Tithonia diversifolia) with fermentation using Lactobacillus plantarum and Aspergillus ficuum at different incubation times

“…Also, it can affect the health and production of animals through mechanisms of decreasing nutrient intake, digestive and RONI PAZLA 1,♥ , NOVIRMAN JAMARUN 1,♥♥ , MARDIATI ZAIN 1 , GUSRI YANTI 2 , RIKI HISKIA CHANDRA 3 absorption disorders and causing other adverse side effects. Oluwasola and Dairo (2016) stated that the most antinutrient content in tithonia was phytic acid, 79.2 mg/100gr. The high phytic acid content in tithonia causes a bitter taste, so it is not liked by livestock.…”

The Effect of Different Farm Altitudes on The Production, Quality, and Mineral Contents of the Etawa Crossbred Dairy Goat’s Milk

“…T. diversifolia grows in the highlands and contains anti-nutritional substances, such as phytic acid, which binds phosphor. The phytic acid content of the tithonia plant is 79.2mg/kg (Oluwasola and Dairo 2016). Furthermore, the phytic acid that enters the rumen will be degraded by microbes, which produce phytase enzymes, thereby allowing the release of bound phosphorus into available form (Pazla et al 2021b;Pazla et al 2021c).…”

Production Performance, Feed Intake and Nutrient Digestibility of Etawa Crossbreed Dairy Goats Fed Tithonia (Tithonia diversifolia), Cassava Leaves and Palm Kernel Cake Concentrate

“…Tithonia is also rich in P mineral, which can potentially increase the number of rumen bacterial populations (Fasuyi et al 2010;Adrizal et al 2021;Pazla et al 2021b). Oluwasola and Dairo (2016) reported that tithonia plants are also rich in amino acids. The mixture of tithonia with elephant grass as a fiber source in ECDG ration can optimize intake, digestibility, and milk production (Pazla et al 2022).…”
