“…(2008) , who reported that reducing dietary Met level (0.36 vs. 0.31%) had no influence on eggshell quality. Moreover, this result was contrary to the previous result that adding taurine (1.96 g/kg diet) increased the egg shell breaking strength in hens after peak production by increasing the integrity of calcium columns and decreased the size of egg shell pores ( Hajjarmanesh et al., 2022 ). The effect of TAU and/or Met on calcium absorption and deposition during eggshell formation needs to be investigated further.…”

“…The unobvious changed laying performance by 21TAU and 42TAU and 0.1%TAU treatment indicated that dietary supplementation of TAU or partial replacement of Met with TAU has no unfavorable influence on the laying performance of hens. This result was in line with the previous work by Hajjarmanesh et al. (2022) , who reported that dietary TAU supplementation (1.96 g/kg diet) had no significant effect on egg production and egg weight of laying hens fed a basal diet with 0.42% digestible Met during 71 to 76 wk of age.…”

“…Thus, the content of Zinc was higher in the blood of experimental B birds compared to experimental A and control, which Hofmann & Hagey (2008) attributed to the dynamics of protein metabolism. As proved by Jegede et al (2011) and Hajjarmanesh et al (2022), the bioavailability of Zinc depends on the levels of phytic acid and Cuprum. Thus, the content of Cuprum in the blood of experimental poultry increases (P < 0.01), which is associated with the active participation of this element in the processes of hematopoiesis and is consistent with the dynamics of haematological parameters in chickens.…”

Using probiotic preparations and their complexes in poultry farming is an important step towards increasing poultry resistance and productivity, and thus producing environmentally friendly products. The purpose of the study was to investigate the effect of the complex action of symbiotic drugs and biocidal agents by investigating the clinical and biochemical parameters of blood and mineral metabolism in the body of broiler chickens under the conditions of their use according to the developed scheme. Hematologic, biochemical and immunologic blood parameters were explored by conventional methods, micro- and macroelements by optical emission spectrometry with inductively coupled plasma. Using the proposed complex of symbiotic and biocidal agents in the technology of rearing broiler chickens activates the processes of erythropoiesis, haemoglobin production, restoration of protein metabolism and normalisation of mineral status within physiological limits, which indicates the strengthening of the body's defences, increased resistance to stress factors and adverse environmental conditions, and will further have a positive effect on the growth and productivity of the target bird. The pronounced effect of the complex combination of drugs on the body of broiler chickens of experimental B is a better assimilation of many inorganic elements (by increasing the content of Calcium, Phosphorus, Cuprum, Ferrum and Selenium, Magnesium, Manganum); and, accordingly, causes the sustainable development of metabolic processes due to the prevalence of anabolic over catabolic processes (by increasing the level of total proteins against the background of a physiological increase in the number of globulin fractions; including the induction of the endogenous detoxification system – by reducing the level of production of toxic metabolites of purine metabolism: uric acid and creatinine; reduction of Chromium content; normalisation of transamination processes and deceleration of alkaline phosphatase activity) and immunobiological reactions (by enhancing erythropoiesis and haemoglobin production; induction of lysozyme, bactericidal and phagocytic activity), respectively. The proposed system of rearing young poultry using a complex of symbiotic preparations in combination with biocidal agents promotes the synergistic effect of the latter and their effective action on the body of experimental broiler chickens, which increases nonspecific resistance and restores metabolic reactions

“…As a constituent of the carbonic anhydrase enzyme, zinc is crucial in preparing bicarbonate ions during eggshell formation. A deficit of this enzyme prevents the secretion of bicarbonate ions (the central particle required for the precipitation of calcium within the frame of calcium carbonate) (Hajjarmanesh et al., 2022 ). It causes a decrease in the weight of the eggshell.…”

Nanotechnology is an innovative, promising technology with a great scope of applications and socioeconomic potential in the poultry industry sector. Nanoparticles (NPs) show the advantages of high absorption and bioavailability with more effective delivery to the target tissue than their bulk particles. Various nanomaterials are available in different forms, sizes, shapes, applications, surface modifications, charges and natures. Nanoparticles can be utilised in the delivery of medicines, targeting them to their right effective site in the body and, at the same time, decreasing their toxicity and side effects. Furthermore, nanotechnology can be beneficial in the diagnosis of diseases and prevention of them and in enhancing the quality of animal products. There are different mechanisms through which NPs could exert their action. Despite the vast benefits of NPs in poultry production, some concerns about their safety and hazardous effects should be considered. Therefore, this review article focuses on NPs’ types, manufacture, mechanism of action and applications regarding safety and hazard impact.
