Chemical composition of green forage in relation to legume plant species and its share in the meadow sward
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 3
Abstract
The aim of the study was to evaluate the impact of various percentage shares of legumes in the sward on the nutritional value of forage. Two species of legume plants were used in this experiment: red clover (Trifolium pratense L.) variety Chlumecky and birdsfoot trefoil (Lotus corniculatus L.) variety Leo. The research material consisted of green forage sam-ples in which percentage shares of tested species of legume plant ranged from 0% to 100%. The content of organic and mineral components in green forage was evaluated. The relation between the percentage shares of red clover and birdsfoot trefoil and the content of nutritive components in green forage was calculated. Forages with birdsfoot trefoil in them, regardless of its percentage share, contained more total protein, crude ash and NDF and ADF fibers fraction. In contrast, forages with the participation of red clover contained more sugars, Ca, Mg and Mn, and were characterized by higher digestibility of organic matter. The proportions of both species also had a significant impact on the content of the majority of nutrients. Increasing the proportion of both red clover and birdsfoot trefoil in green forages resulted in a decrease in crude fiber content and its fractions: ADF and NDF. However, the share of both species was positively correlated with the total protein content, crude ash, ADL and organic matter digestibility. A positive correlation was found between the proportion of red clover in mixture and the Ca, Mg and Fe contents. The proportion of birdsfoot trefoil was positively correlated with the content of P, Ca, Mg and Fe.
