A systematic weekly cutting of timothy grass over the period of the first regrowth allowed to evaluate the changes in yields, chemical composition as well as energetic value and organic matter digestibility over different development phases of the species. The range of the changes was presented as multi-factorial regression equations. A majority of the parameters studied had a high determination coefficient. Over the whole vegetation period yields and the fibre content were higher, while total protein, PDIN, PDIE and PDIF, as well as fat gross energy, UFL, UFY, ash, calcium and phosphorus content were decreasing. The most remarkable changes were noted the period from spreading to earing, white the magnitude of changes decreased over the period of flowering and seed maturing. The most significant changes of energy concentration and its digestibility as well as organic matter digestibility were noted at the last cuts. A significant effect of thermal conditions and the rainfall on the timothy grass development was observed in the spring time. A difference of a dozen days in the earing time was noted over the study period of four years. As results from the fibre content, a later earing time was accompanied not only by increasing yields but also by higher fibre amounts. In the same periods drought and high temperatures caused a decrease of the amount and digestibility of energy. Besides, weather conditions (cold or hot spring) changed directions of the changes of soluble sugars and fat accumulation as well as calcium and phosphorus content.
