Anaerobic degradability and acid hydrolysis organic manure as an illistration of dietary organic matter utilization in crows in relation to lactation period.
Original language description
The objective of the present paper was to verify a hypothesis whether the method of studying the anaerobic degradability of organic matter of excrements could reveal the utilization of dietary organic matter in the digestive tract of ruminants in relation to lactation period and application of a mineral product and whether it could be replaced by a cheaper and easier method of acid hydrolysis of excrements. Changes in anaerobic degradability and hydrolysis yields of excrements were investigated in an experimental herd of 30 cows divided into two groups differing in lactation period by 30 days. The results document that anaerobic degradability is a suitable indicator of anaerobic digestion conditions in the digestive tract of animals and of the fitness of their organism. However, the results of excrement hydrolysis according to the Rovira et Vallejo (2002) method were hardly reproducible and so they could not be used, if only the very labile organic fraction LPI is evaluated. The evaluation of the sum of fractions LPI and LPII (semi-labile fraction) provides easily available values, but these are only orientative values that cannot replace the costly and labour-consuming determination of anaerobic degradability of excrements.
