On the get together of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder plants (NVWV) agreed to arrange a global Symposium on an issue on the topic of in depth grass and fodder creation structures. The subject matter chosen was once "Animal manure on grassland and fodder plants: Fertilizer or waste?" This Symposium was once geared up 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 attached with the disposal of animal waste have obtained a lot consciousness in recent times, specifically in areas with extensive animal of animal manure consistent with hectare agricul husbandry. while the creation tural land elevated strongly, the necessity for it diminished end result of the advent of inexpensive inorganic fertilizers that are more uncomplicated to address and feature a extra trustworthy impression on crop progress. as a result, many farmers put off animal manure as cost effectively as attainable, when keeping off harm to grassland and plants and paying little realization to potent use of the crops foodstuff inside the manure. current practices of manure dealing with and alertness frequently result in environmental difficulties. the increase in expertise of those difficulties renewed curiosity in chances to enhance the usage of nutrition from animal manure in crop construction. examine in this subject has been influenced in lots of international locations over the last decade and the purpose of this Symposium was once to check and investigate present-day knowledge.

Minimum loss of nitrogen by dairy cows Maintenance In a recent review Owens  concluded that a 600 kg cow fed at maintenance level loses 52 to 82g N day-l (Table 1). Several factors attribute to this minimum N loss. A small proportion is lost with skin and hair. g. amino acids, nucleic acids) expelled during metabolic processes of body tissues. A third route of N excretion is faecal output. Metabolic faecal N (MFN) consists of the residues of secreted enzymes, sloughed intestinal cells and of the gastro-intestinal biota.

Influencing proteolysis in the forestomachs has also been attempted by using formaldehyde treatment to affect the molecular structure of proteins or Monensin to affect the metabolism of microbes. However, the effects have been found variable .
