Evaluation of productivity of fodder area in chosen dairy farms in Lublin voivodeship

Abstract

Summary. The evaluation of productivity of fodder area in dairy farms localized in three regions differentiated by habitat conditions in Lublin voivodeship is presented in the paper. The method which was used during the research was a survey and the basic instrument was a questionnaire. The study was conducted in 145 farms. The productivity level of fodder area types, expressed by chosen indexes was regionally differentiated and dependent on the number of cows in a herd. Less productivity of the natural fodder area was achieved by farms in which grasslands area per 1 livestock unit was the biggest. The productivity of the basic forage area, measured in kg of protein, was mostly influenced by: cereal yields, grasslands area per 1 LU, their share in the agricultural acreage, the share of feed in a special area of arable land and their share in forage area in the agricultural acreage. Its level, however, expressed in MJ of energy was mainly affected by the area of farmland, the share of maize in the crop structure and the size of the non-economic forage area. The productivity of the forage area, expressed in units of cereal was mostly affected by the area linkage per 1 LU of their proportion in the agricultural acreage, grain yields, the share of feed in a special area of arable land and their share in the forage area in the agricultural acreage.
