In world practice biologically active drugs are widely used at different technological stages of rearing pigs, poultry and cattle. Special attention should be paid to bio-grugs obtained not as a result of chemical synthesis, but isolated from organs and tissues of healthy animals. Restoration of normal intestinal microflora of the animal is the basis of the concept of probiotics. Currently, probiotics are considered as endogenous intestinal microflora most often belonging to the group of lactobacilli, streptococci or bifidobacteria or as specific growth factors for them. Probiotics are selected according to certain criteria based on scientific knowledge of the physiology of intestinal microbiology, as well as animal nutrition. The purpose of the work was to study the effect of biological products on resistance, reproductive, fattening and meat productivity of pigs, on the quality of whole-muscle and fine-structured pork products; to develop a method of application of duodenum extract in combination with probiotics to increase the productivity of pigs. Studies on the effect of extracts derived from endocrine cells of the intestine, in combination with probiotics on the productivity of pigs of Large White breed and the quality of pork, as well as studied the effect of duodenins and probiotics in different concentrations on the protective properties of animal blood have been carried out. New methods of application of extracts of endocrine cells of intestines and probiotics for increase of meat productivity of animals and quality of pork have been offered. The use of bio-drugs increased the livability of young animals in all experimental groups from 1st to 4st by 3,51; 6,05; 4,95 and 5,90 %, respectively. There was an advantage in the amount of revenue from the sale of products of all experimental groups over the control one.

This experiment was conducted and aimed to reducing mortality and losing the weight of birds transported to the slaughter house through reducing or Transport stress removal and thus to reduce financial losses. 150 birds used almost equal weights that were divided into three treatment groups and by five replicates for each treatment is control treatment (T1) without giving anything and treatment with salicylic acid concentration 1 g / liter of drinking water (T2) and treatment with ascorbic acid (T3) concentration 0.5 g / Liter of drinking water provided 24 hours before its transport. The transport process resulted in a highly significant decrease (P ≤ 0.01) in body weight in treatment T1 as it reached 4.66%, while it reached 1.68 and 1.09% in treatment T2 and T3, respectively. The transport process led to an increase in body temperature, H / L ratio, the concentration of glucose, aspartate transaminase (AST) and alanine transaminase (ALT) in the blood serum, as the transport process led to a very significant decrease (P ≤ 0.01) in the cholesterol concentration, Uric acid, intestinal villi length and crypts depth. T2 and T3 treatments showed their ability to reduce transport stress, especially T3, where they outperformed T1 in most traits. It is concluded from the study that adding ascorbic acid by 0.5 g / L drinking water 24 hours before transporting the chicks to the slaughter house reduces the transport stress and lessen financial losses, so it is recommended to use it.

Background: According to the views of psychoneuroendocrinoimmunology, many interactions exist between nervous, endocrine and immune system the purpose of which is to achieve adaptive measures restoring an internal equilibrium (homeostasis) following stress conditions. The center where these interactions converge is the hypothalamus. This is a center of the autonomic nervous system that controls the visceral systems, including the immune system, through both the nervous and neuroendocrine mechanisms. The nervous mechanisms are based on nervous circuits that bidirectionally connect hypothalamic neurons and neurons of the sympathetic and parasympathetic system; the neuroendocrine mechanisms are based on the release by neurosecretory hypothalamic neurons of hormones that target the endocrine cells and on the feedback effects of the hormones secreted by these endocrine cells on the same hypothalamic neurons. Moreover, the hypothalamus is an important subcortical center of the limbic system that controls through nervous and neuroendocrine mechanisms the areas of the cerebral cortex where the psychic functions controlling mood, emotions, anxiety and instinctive behaviors take place. Accordingly, various studies conducted in the last decades have indicated that hypothalamic diseases may be associated with immune and/or psychic disorders. Objective: Various researches have reported that the hypothalamus is controlled by the cerebellum through a feedback nervous circuit, namely the hypothalamocerebellar circuit, which bi-directionally connects regions of the hypothalamus, including the immunoregulatory ones, and related regions of the cerebellum. An objective of the present review was to analyze the anatomical bases of the nervous and neuroendocrine mechanisms for the control of the immune system and, in particular, of the interaction between hypothalamus and cerebellum to achieve the immunoregulatory function. Conclusion: Since the hypothalamus represents the link through which the immune functions may influence the psychic functions and vice versa, the cerebellum, controlling several regions of the hypothalamus, could be considered as a primary player in the regulation of the multiple functional interactions postulated by psychoneuroendocrinoimmunology.
