“…It was also noticed that the presence of green macroalgae Enteromorpha prolifera and Cladophora sp. in laying hens' diet influenced advantageously egg weight, eggshell thickness, as well as the body weight of hens [19]. Also Witkowska et al (2014a) showed that the qualities of eggshell strength, eggshell thickness, albumen height and yolk color of the hens fed with soybean enriched via biosorption were enhanced.…”

Abstract:The aim of the study was to perform feeding experiments on growing pigs in order to assess the impact of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions via the biosorption process on the mineral composition of blood, meat, liver, feces and urine. In the control group, microelements were supplemented as inorganic salts, whereas in the experimental groups they were replaced by enriched macroalga. After 3 months of the feeding experiment, it was found that the meat was biofortified with Cr, Mn, Fe, Cu and Zn. The average content of Zn in the blood from the pigs fed with algae was higher by 9.5%, compared to that in the blood from pigs in the control group. The liver of growing pigs from the experimental group contained 16% less Cu and 18% less Zn than the liver in the control group. Growing pigs fed with macroalgae excreted in feces 27% more Zn than growing pigs in the control group, but 3.5 times less Cu. It could be concluded that the bioavailability of microelements to pigs from algae was higher than from the inorganic salts. Baltic macroalgae enriched with microelement ions could be potentially used as a biological feed additive.

“…erefore, in the feed industry and among breeders, there is an increasing interest in the possibility of using new materials such as algae enriched in microcomponents [11], fossil materials [12], food industry waste such as yeast [13], and other organic waste [5]. e appropriate content of macro-and microelements in compound feed is also necessary from the point of view of production economics because it will not only allow obtaining products with an increased content of these ingredients but also help to maintain the health and production parameters of animals at an optimal level [14].…”

In recent years, there has been a steadily growing demand for animal protein. Consumer awareness is also growing every year, which is why breeders are obliged to provide animals with the best possible environmental conditions that will determine the productivity of animals and the quality of raw materials obtained from them. Today's consumer is looking for not only the highest quality food but also the one that will characterize health-promoting properties.erefore, food is sought, which will be characterized by a favorable profile of fatty acids and a high content of biologically active ingredients, such as vitamins or minerals. One of the most effective methods of enriching food with these ingredients is their supplementation in feed. However, it should be remembered that the form in which such a component will be delivered is very important. High hopes are associated with the possibility of using organic forms of macro-and micronutrients, which are sometimes better absorbed than inorganic salts. e aim of the work was to collect and systematize knowledge related to the possibility of enriching food of animal origin with micronutrients using additional feed containing these ingredients in organic form.

“…In our previous studies we showed that biomass enriched with microelement ions constituted a source of highly bioavailable minerals to animals (laying hens, pigs, goats) and can partly replace traditionally used inorganic salts as a main source of microelements [20][21][22]. In these studies it was shown that the bioavailability of microelements from the enriched biomass was higher than from inorganic salts.…”

“…Before the analysis, enriched biomass (about 0.5 g) was digested with 5 mL of concentrated 69% nitric acid (Supra pure grade from Merck, Darmstadt, Germany) in Teflon bombs in a microwave oven (type Milestone MLS-1200 MEGA, Bergamo, Italy). The solution after mineralization was diluted to 50 mL and analysed by ICP-OES [20,31].…”

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.
