Conventional versus green ZnO nanoparticle pre-treatment effects on Mucuna pruriens utilis seed potential nutritional value for beef cattle

P. G., Nozipho and M. N. M., Doctor and M. M., Caven and M., Sydney and C. O., Damian (2024) Conventional versus green ZnO nanoparticle pre-treatment effects on Mucuna pruriens utilis seed potential nutritional value for beef cattle.

The utility of Mucuna pruriens utilis seed meal (MSM) in beef cattle nutrition is limited by high fibre content and antinutritional factors. Hence, this study investigated conventional (C- Nano-ZnO) and green (G-Nano-ZnO) ZnO nanoparticle pre-treatment effects (0, 1, 5, 10, 15, and 20 mg/kg) on the legume’s nutritional composition and in vitro ruminal fermentation. Both nanoparticle types differentially increased DM, OM, and EE (P < 0.001) and tended to increase ash (P = 0.055) whilst they decreased NDF, ADF, ADL, cellulose (P < 0.001), and hemicellulose (P < 0.01) contents of MSM, with 20 mg/kg G-Nano-ZnO inducing greater effects. Also, they increased MSM’s Ca (P < 0.001), P (P < 0.001), Mg (P < 0.001), S (P < 0.001), Fe (P < 0.001), and K (P < 0.001), with 20 mg/kg C-Nano-ZnO generally inducing greater effects. However, both nanoparticle types generally induced no effects on MSM’s CP, Cr, Mn, Rb, gas production rate, in vitro ruminal gas production kinetics, and cumulative gas production (P > 0.05), except for increased 12 h post-incubation gas production rate induced by 20 mg/kg G-Nano-ZnO (P < 0.001) and decreased immediately degradable DM fraction a (P < 0 .001) and 12 h post-incubation cumulative gas production (P < 0.001) induced by, respectively, 20 mg/kg G-Nano-ZnO and 15 mg/kg C-Nano-ZnO. Interestingly, both nanoparticle types increased in vitro ruminal OM degradability and partitioning factors (P < 0.001), with 20 mg/kg G-Nano-ZnO inducing greater effects. In conclusion, pre-treatment with 20 mg/kg G-Nano-ZnO mostly enhanced potential nutritional value of MSM.

Abstract

The utility of Mucuna pruriens utilis seed meal (MSM) in beef cattle nutrition is limited by high fibre content and antinutritional factors. Hence, this study investigated conventional (C- Nano-ZnO) and green (G-Nano-ZnO) ZnO nanoparticle pre-treatment effects (0, 1, 5, 10, 15, and 20 mg/kg) on the legume’s nutritional composition and in vitro ruminal fermentation. Both nanoparticle types differentially increased DM, OM, and EE (P < 0.001) and tended to increase ash (P = 0.055) whilst they decreased NDF, ADF, ADL, cellulose (P < 0.001), and hemicellulose (P < 0.01) contents of MSM, with 20 mg/kg G-Nano-ZnO inducing greater effects. Also, they increased MSM’s Ca (P < 0.001), P (P < 0.001), Mg (P < 0.001), S (P < 0.001), Fe (P < 0.001), and K (P < 0.001), with 20 mg/kg C-Nano-ZnO generally inducing greater effects. However, both nanoparticle types generally induced no effects on MSM’s CP, Cr, Mn, Rb, gas production rate, in vitro ruminal gas production kinetics, and cumulative gas production (P > 0.05), except for increased 12 h post-incubation gas production rate induced by 20 mg/kg G-Nano-ZnO (P < 0.001) and decreased immediately degradable DM fraction a (P < 0 .001) and 12 h post-incubation cumulative gas production (P < 0.001) induced by, respectively, 20 mg/kg G-Nano-ZnO and 15 mg/kg C-Nano-ZnO. Interestingly, both nanoparticle types increased in vitro ruminal OM degradability and partitioning factors (P < 0.001), with 20 mg/kg G-Nano-ZnO inducing greater effects. In conclusion, pre-treatment with 20 mg/kg G-Nano-ZnO mostly enhanced potential nutritional value of MSM.
