“…Rare earth chitosan chelate salt (RECC), a new chelate salt, was produced through the coordination chelation effect between rare earth ions and chitosan [ 17 ]. Dietary supplementation with 175~200 mg/kg of RECC improved the immune and anti-oxidant capacity and growth performance of broilers [ 18 ], 200 mg/kg RECC improved the growth, immunity, and microbial balance of weaned piglets [ 19 ], 800 mg/kg enhanced the growth performance and immunity of Carassius auratus gibelio [ 20 ], and 5 g/kg may improve intestinal health and digestive capacity of Leiothrix lutea [ 21 ]. Therefore, RECC chelated through special processing with chitosan probably has both the chemical properties of rare earth and the biological function of chitosan.…”

Rare earth chitosan chelate salt (RECC) is a potential feed additive and is a product of the chelation effect between rare earth ions and chitosan. This research study aims to explore the effects of dietary RECC on performance, egg quality, intestinal digestive function, and the immune and antioxidant capacity of laying hens in the late phase of production. A total of 360 56-week-old Dawu Jinfeng laying hens were randomly allotted into four treatment groups with six replicates per treatment and 15 birds per replicate. The laying hens were fed the basal diet supplemented with, respectively, 0 (control: CON), 100 (R1), 200 (R2), and 400 (R3) mg/kg for 8 weeks. Dietary RECC significantly improved average daily feed intake (ADFI) and average daily egg yield in both linear and quadratic manner (p < 0.05). In addition, albumen height and HU were improved significantly (p < 0.05) in a dose-dependent manner of RECC. In addition, a significant decrease (p < 0.05) in serum TP, IgA, and MDA for the R1 group and IgG in the R2 group were notable, while the increase in serum TP and decrease in T-AOC were found for R3 dietary group compared to CON (p < 0.05). The level of intestinal IL-2 and TNF-α was decreased by dietary RECC (p < 0.01). The activities of the digestive enzyme (α-Amylase, lipase, and Trypsin) showed a quadratic change with an increase and then decrease in response to increasing dose of RECC, 200 mg/kg RECC significantly increased the activity of lipase and Trypsin (p < 0.01). Supplementation of dietary RECC at low doses compared to higher doses impacted positive effects on the antioxidant capacity and immune function (p < 0.05). The utilization of RECC as a feed additive in the diet of aged laying hens exerted beneficial effects on egg production, albumen quality, humoral immunity, inflammatory response, and activity of digestive enzymes. Thus, the regulation of antioxidant capacity and duodenal function via increased enzyme activity and immune and inflammatory response were critical to the improvement of laying performance and egg quality in aged hens. The optimal supplemental dose is 100–200 mg/kg.

“…In particular, the addition of 200 and 300 mg/kg of cerium dioxide to the feed of laying hens led to a significant (p<0.01) increase in the breaking strength of the eggshell. The concentration of Calcium and Phosphorus in blood serum increased significantly (p<0.05) after the administration of 100 mg/kg of cerium oxide [5]. It was also noted that the superoxide dismutase activity and concentration of malondialdehyde (MDA) in blood serum significantly decreased with the addition of cerium dioxide.…”

“…In recent years, there have been reports in the literature about the use of metal nanoparticles, in particular cerium, in animal husbandry, since the use of antibiotics as growth promoters is prohibited in the European Union. It is reported that rare earth elements (REEs) can be successfully used as new natural feed additives to increase animal productivity [5,7].…”

The scope of application of cerium dioxide and its special physical and chemical properties are considered in the work. The effect of the size factor on the properties of nanodispersed cerium dioxide determines the biological activity of the material, low toxicity and high oxygen non-stoichiometry. Specific properties of CeO2 include the ability to regenerate oxygen non-stoichiometry, which is expressed in the ability of cerium dioxide nanoparticles to return to their initial state after participating in the redox process in a relatively short period of time, which enables their repeated use. Nanoparticles, due to their small size, easily penetrate into the body through the respiratory, digestive, and skin organs and exhibit more pronounced biological activity due to the large surface area per unit mass. The change in the physical and chemical mechanisms of action of nanoparticles is due to the fact that most of the atoms are on the surface. Such an arrangement changes the physical, chemical, biological, toxicological properties of the substance and facilitates the interaction of nanoparticles with a living organism. Once inside a biological system, nanoparticles come into contact with a number of physical and chemical features of the organism, which affect their properties and can change the response. These features are largely due to the ability to pass through the redox cycle between two natural oxidation states (Ce3+ and Ce4+). The influence of cerium dioxide nanoparticles on metabolic processes in the body of broiler chickens has been established. Their introduction contributed to an increase in the content of total lipids in the blood by 24.6–31.3 %, albumins – by 16–22 %, and a decrease in the content of uric acid to the level of 63–67 % of the control. Non-toxicity of poultry meat treated with nano-cerium for consumers was established. The high degree of biocompatibility, low toxicity and catalytic activity of nanodispersed cerium dioxide make it possible to consider it as a promising nanobiomaterial for use in biology, medicine and agriculture. Key words: nanobiotechnologies, nanoparticles, ceriumdioxide, layinghens, lipids.

The purpose of the research was to determine the effectiveness of using the chitosan complex “KX-1” in the technology of feeding broiler chickens under conditions of increased stocking density of 23.5 birds/m². Broilers of the 1st control group received feed with standard nutritional value; broilers of experimental groups 2-4 were additionally introduced to a similar diet with a chitosan complex at the rate of 50, 70 and 100 g/t throughout the entire growing period. It was found that the highest efficiency of growing broiler chickens was in the 3rd experimental group, which received the chitosan complex “KX-1” at the rate of 70 g per 1 ton of feed. At 39 days of age, the chickens of this group in live weight exceeded their peers from the control group by 3.5%, from the 2nd experimental group - by 1.9%, and from the 4th experimental group - by 1.2%. The European productivity index in the 3rd experimental group was 9-20 units. (2.3-5.3%) higher than in other groups. The chitosan complex “KX-1” had a positive effect on the zootechnical parameters of poultry rearing under conditions of increased stocking density at a broiler factory and is a valuable feed additive for broilers.
