FEED BEHAVIOR OF BREED NUTRITION AND FORECASTING CONSUMPTION OF ANIMAL FEEDING IN ANIMAL GRAZING ORGANIZATION

Abstract

The article deals with the use of parameters of fodder behavior of cattle and productive characteristics of herbage for the purpose of rational use of pasture. As a result of the review of literary sources on technological aspects of feeding of ruminants, an analysis of the current status of the study of issues related to the organization of the use of pastures in dairy cows during the summer is made. In particular, the main parameters and factors that determine the conditions of their nutrition on the pasture are analyzed: productive characteristics of the grass, peculiarities of feeding behavior of animals, duration of grazing of animals, etc. It was found that only the maximum consideration of the abovementioned parameters in the planning of grazing can provide a high level of productivity of animals in pastures. Analyzing literary sources in the direction of technological aspects of the use of natural lands with ruminants, it has been established that pasture is an integrated system whose rational use requires special knowledge and skills that provide an assessment of animal nutrition conditions and, if necessary, the planning of their feeding. This paper examines the results of experimental studies on pastures that allow a clearer idea of the relationship between animal feed behavior, grass field performance, feed consumption and animal productivity, and also discusses the main models used to predict feed intake. The article notes that in most studies, attention is focused mainly on qualitative indicators of herbage, on the indicators of its nutritional value, and practically does not pay attention to the supply of feed, productive indicators of herbs (considering that in the presence of high–quality pasture grass the animals will be able to eat enough feed), which ultimately leads to an underestimation of animal feed intake, and therefore to a decrease in their productivity. That is why, under such a traditional approach, it is not possible to adequately assess the conditions of feeding animals, and therefore rationally organize their feeding. In this regard, the article analyzes in detail the influence of the productive indices of grassland pastures on feed consumption and animal productivity. Thus, estimation of feeding conditions of cows on pastures should be carried out precisely through the prism of features of animal feed behavior, productive characteristics of herbs, which will allow to provide effective recommendations for the rational use of such kind of grounds by animals.
