Influence of feed supplementation with probiotic and organic form of zinc on functional status of broiler chickens.

Background: The increase in the intensity of agricultural production is associated with the action of various stress factors on the organism of birds, which can lead to negative consequences. Prevention of the development of stress conditions in farm birds, particularly broiler chickens, in industrial production, is the most important task facing scientists and practitioners.

Aim: The objective of this study was to investigate the effect of a combined probiotic preparation and zinc glycinate on the indicators of immunity, biochemical parameters, and antioxidant status.

Cytokine and immunoglobulin profiles of Arbor Acres broiler chickens at different stages of physiological development.

Background And Aim: Modern scientific research focuses on a detailed study of the immune system, the mechanisms of immunosuppression, and the search for an effective means to restore disturbed immune homeostasis in farm animals. The present study examined the cytokine and immunoglobulin (Ig) profiles of healthy broiler chickens during physiological development.

Materials And Methods: Arbor Acres broilers (n = 28) were used in the study to achieve this objective.

Effects of the combined use of a probiotic and chromium methionine chelate on the functional state of broiler chickens.

Background And Aim: An increase in the productivity of broiler chickens is possible when creating an optimal food base that provides birds with all of the nutrients and biologically active substances required for the fullest realization of their genetic potential. In this regard, we examined the effects of the addition of a water-based probiotic and a chelated form of chromium (Cr) to the diet of birds.

Materials And Methods: Sixty 14-day-old male Arbor Acres broilers were used in this study.

The assessment of serum trace element levels as the diagnostic biomarkers of functional state of broiler chickens.

Background And Aim: Elemental analysis is a useful technique for predicting metabolic disorders in broiler chickens. Elemental imbalances are also important for the development of new methods to diagnose the health status of birds that can be implemented on a farm-wide scale. This study aimed to identify elemental markers related to pre-nosological diagnoses of metabolic disorders in broiler chickens.

Elemental composition of the hair and milk of black-spotted cows and its relationship with intestinal microbiome reorganization.

Background And Aim: The cattle breeding system is facing severe problems associated with the increased negative impact of various human activity areas on the environment and the bodies of farm animals. The use of heavy metals in different production areas leads to their accumulation in the environment due to the ingestion of animals and humans through animal products. This study aimed to assess the elemental composition of the hair and milk of black-spotted cows and to identify the relationship between the content of toxic and essential elements and the state of the intestinal microbiome.
