adaptation of fleckvieh cows to climates and nutrition conditions in the western part of romania

Our research sets out to quantify the way in which the nutritional value of the food ratios influences the milk production in Fleckvieh cows which were imported in Agriland ranch in the summer of 2008, from Germany. The different types of fodder existent at the ranch and their supply in the animals’ ratios according to the season has been taking into consideration when calculating the nutritional value which has been afterwards compared with the expected values. The main objective was estimating the potential production and then comparing it with the real one obtained in the ranch, under the specific conditions of shelter and feeding. The health of the animals has also been observed. The evolution of the real graphic of lactation is very different from the potential one, in the sense that in the first two or three months of lactation the production decreases, and its peak is somewhere between the fourth month and the fifth month. This proves a feeding which is not proper, because it is not differentiated by production. The ratios should be made proper and this is done relatively easy by including phosphates into the ratio. The energy level can be corrected by individually administering the concentrated fodder which has to be correlated with the milk production.
