Biomass Enriched with Minerals via Biosorption Process as a Potential Ingredient of Horse Feed

Abstract

In the present work, dry plant biomass that is commonly used in horses feeding: alfalfa, chopped grass pellets and chopped grass was used as a biosorbent of microelement ions: Cr(III), Zn(II), Cu(II) and Mn(II). Biosorption process was used to potentially enhance supplementation of minerals in horses diet. In order to characterize the biosorption properties of the examined biomass, preliminary experiments (kinetics and equilibrium studies) were conducted with Cr(III) ions. The effect of pH and initial metal ions concentration (C 0 ) on the biosorption capacity (q) was investigated. On this basis, the best experimental conditions were chosen (pH 5, C S 1.0 g/L (biomass content), C 0 200 mg/L). For them, biosorption of Mn(II), Zn(II), Cu(II) ions was carried out in a periodic and continuous system (biosorption column). Equilibrium of the biosorption was described using Langmuir equation. The mineral composition of the raw and enriched biomass was also examined using ICP-OES, as well as SEM-EDX technique. In general, the best biosorption properties were observed for alfalfa. The maximum biosorption capacity for Zn(II) was 27.5 mg/g, for Cu(II)-38.5 mg/g, for Mn(II)-13.6 mg/g and for Cr(III)-33.2 mg/g. Therefore, the biomass of enriched alfalfa can be recommended as a feed supplement for horses.

A comprehensive analysis of biosorption of metal ions by macroalgae using ICP-OES, SEM-EDX and FTIR techniques

“…The aim of the present paper was to obtain and characterise a feed additive for animals, especially for equine nutrition based on the biomass of a freshwater macroalga– Cladophora glomerata . The biomass was enriched separately with Cr(III), Mn(II) and Mg(II) ions, because they seem to be crucial in an equine clinical nutrition [ 3 , 12 , 18 , 24 ]. In a dietary management of horses, especially with a diagnosed metabolic syndrome, soaking of hay in water is also recommended.…”

Influence of Non-Traditional Feed Additives on the Quality of Horse Breeding Products

“…In accordance with the research program, the control group of milking mares received the main household diet, which is presented in table 1, and animals of the I and II experimental groups, in addition to the main household diet, received Zeolite-Sapropel feed additives once a day in the norm: zeolite 0.5 g per kg of body weight with 200 and 300 g of Sapropel, respectively. The theoretical basis of these studies was the work of scientists on the problems of using natural mineral feed additives in the feeding of farm animals (Adegbeye et al, 2019;Michalak et al, 2019;Neustädter et al, 2019). In the process of conducting research, there were used methods that are generally accepted in animal husbandry: analytical, biochemical and statistical.…”

Valorization of Biomass Residues by Biosorption of Microelements in a Closed-Loop Cycle

“…Valorization of plant residue of pharmaceutical, cosmetic, and food origin is a new opportunity for a circular economy enabling biomass used as a food supplement for livestock production [2,3]. A good example comes from a soybean meal commonly used in livestock farming as a source of assimilable protein.…”

“…The biomass of algae enriched with Cu was used in swine breeding, its bioavailability [7]. Feed additives obtained through sorption of Cr, Zn, Cu and Mn ions on alfalfa biomass were used as potential ingredients in feed for hen husbandry [2].…”
