On the celebration of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder vegetation (NVWV) agreed to arrange a world Symposium on a subject matter relating to in depth grass and fodder construction structures. The subject chosen was once "Animal manure on grassland and fodder vegetation: Fertilizer or waste?" This Symposium used to be prepared lower than the auspices of the ecu Grassland Federation and held on the foreign Agricultural Centre in Wageningen from 31 August to three September 1987. the issues hooked up with the disposal of animal waste have bought a lot recognition in recent times, particularly in areas with extensive animal of animal manure in keeping with hectare agricul­ husbandry. while the construction tural land elevated strongly, the necessity for it lowered due to the advent of inexpensive inorganic fertilizers that are more straightforward to address and feature a extra trustworthy impression on crop progress. in this case, many farmers cast off animal manure as affordably as attainable, while heading off harm to grassland and vegetation and paying little cognizance to powerful use of the crops food inside the manure. current practices of manure dealing with and alertness usually result in environmental difficulties. the increase in understanding of those difficulties renewed curiosity in percentages to enhance the usage of meals from animal manure in crop construction. examine in this subject has been encouraged in lots of international locations over the past decade and the purpose of this Symposium was once to check and investigate present-day knowledge.

However, the NEL/CP ratio in the pressed residue is only changed moderately compared to the original material [24]. Furthermore this method is expensive and energy consuming. Several research groups have tried to increase protein supply to the small intestine by inhibiting protein degradation in the forestomachs. One approach has been the inclusion of tannin containing legumes like sainfoin (Onobrychis viciifolia [4]) or Lotus pedunculatus [2]. Proteolysis of tanninprotein complexes is reduced or takes place more slowly.

Data from Peperzak et al. [16] are illustrative. l to 1%. In fresh chicken manure organic phosphate may amount to 60% of total phosphate, in pig manure to 40%. Faeces contribute most to the total as well as to the organic phosphate. In urine, P is mainly present in the form of inorganic phosphates [10]. Using another fractionation procedure, Gerritse [8] found that the main organic phosphates in fresh pig slurry were inositol hexaphosphate (phytin) and adenosine triphosphate. Transformations during storage and treatment Nitrogen compounds When faeces and urine are deposited, their composition immediately starts to change.
