Workability, endurance and energy shifts in consolidation and memory in aggressive and non-aggressive animals and and Neurochemical profile

Aggression is a motivational behaviour which has a definite direction. On the other hand, we can consider it as a reason of social degradation or it can be viewed as a population and civilization suppressor. Insensive researches are being carried out in resent years in order to define the characteristic mechanisms of aggression, for example, to determine the emotional condition of the subject. Emotions are specific objective changes typical for viability which are identified through biochemical, electrophysiological, motor functions (2,4,9). This is why the objective of our work is to determine endurance and workability in aggressive and non-aggressive animals

Causes, consequences and biomarkers of stress in swine: an update

BACKGROUND: In recent decades there has been a growing concern about animal stress on intensive pig farms due to the undesirable consequences that stress produces in the normal physiology of pigs and its effects on their welfare and general productive performance. This review analyses the most important types of stress (social, environmental, metabolic, immunological and due to human handling), and their biological consequences for pigs. The physio-pathological changes associated with stress are described, as well as the negative effects of stress on pig production. In addition an update of the different biomarkers used for the evaluation of stress is provided. These biomarkers can be classified into four groups according to the physiological system or axis evaluated: sympathetic nervous system, hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-gonadal axis and immune system. CONCLUSIONS: Stress it is a process with multifactorial causes and produces an organic response that generates negative effects on animal health and production. Ideally, a panel of various biomarkers should be used to assess and evaluate the stress resulting from diverse causes and the different physiological systems involved in the stress response. We hope that this review will increase the understanding of the stress process, contribute to a better control and reduction of potential stressful stimuli in pigs and, finally, encourage future studies and developments to better monitor, detect and manage stress on pig farms

Palynological and Archaeological Evidence for Ritual Use of Wine in the Kura-Araxes Period at Aradetis Orgora (Georgia, Caucasus)

Pollen and non-pollen palynomorphs from two zoomorphic Kura-Araxes vessels (ca. 3000 b.c.) from Aradetis Orgora suggest they were utilized for the ritual consumption of wine and likely represent the beginning of the enduring tradition of animal-shaped wine-drinking containers in Georgia. This hypothesis is supported by archaeological and geoarchaeological data: they resemble later wine-containing vessels from Georgia and elsewhere and were found in a building whose context is suggestive of a small shrine. Their palynological spectra match those of present-day wine and wine containers of other periods. One of them was intact, with only a small access hole; consequently, its palynological spectrum can be utilized as a standard for determining the presence of wine in other archaeological vessels. Palynological analyses from different contexts of the Aradetis Orgora settlement and its cemetery (Doghlauri) yielded other significant results regarding the practice of viticulture and the cultural relevance of wine during the Kura-Araxes period
