The effect of changing the stereotype in conditions of a dairy farm on the functional status of dairy cows and dynamics of their yields
According to Professor A.D. Sineshchokov the daily regular repetition of the same routine on the farm causes the production of conditioned reflexes in animals, which provide the normal course of physiological processes. A certain consistency and accuracy in time work on the farm causes the conditioned-reflex training of the animals to milking, eating and so on [2]. Violation of the usual animal order of the day always leads to a more or less severe violations in the course of physiological processes, and often ruin them. In the practice of animal husbandry there is a huge number of facts and cases similar to the above, when under the influence of the external environment the productivity of animals changes dramatically, the basis of which is a change of metabolic processes regulated by the nervous system and, first of all, the cerebral cortex. The influence of external factors that could have an impact through the cerebral cortex on the course of internal processes that determine animal productivity, in many cases it should be considered by livestock producers when establishing their daily routine on the farm. On October 24, 1980, the Council of Ministers of the USSR adopted the decree "On procedure of calculation time on the territory of the USSR", which set the annual transition from winter time to summer and back again. Some experts asserted that the body adapts quickly to moving arrows, and saves energy in large quantities. Others argued that the saving is not more than 1%, and the biorhythms of the body lose their way, causing stress or jet-lag (from the Latin "de" - a negative particle and Greek "synchronisms" -"the coincidence in time"). Canadian scientists have found that in the first days after such transitions to a new time the number of car accidents doubles. Swedish scientists have noted that the most probable spring desynchronosis is more actual. Weakened during winter the body is rebuilt into a summer mood and biorhythms go astray. There is even a special term - "a syndrome of spring fatigue". In 2011 Russia abolished the seasonal transition time. Currently in the mass media the need to return to the translation watch hands is being discussed again - with the purpose to increase daylight and save electricity consumption. The article presents data on the effect of seasonal transition of the calculation time to the daily rhythm of milking cows and dynamics of their yields. The expediency of preservation of a mode of the day on a dairy farm in a constant time mode has been stated in the article.
