COMPOSTING OF RABBIT MORTALITIES IMPLEMENTD IN THE EXPERIMENTAL FARM AT CHAPINGO AUTONOMOUS UNIVERSITY

Abstract

In order to investigate the feasibility of composting rabbit carcasses with various substrates, six treatments were established according to the substrate used: oat straw-rabbit manure-dead rabbit (PAEC), wood shavings- rabbit manure- dead rabbit (EVC) and oat straw-dead rabbit (PAC), with or without the addition of 0.3 % ( v / w) mixed microbial inoculum consisting of Streptomyces spp, Aspergillus sp, Cladosporium sp. Temperature, pH, dry matter (DM ), moisture, organic matter (OM), ash and ammonia was measured. The substrates were aerated by turning at 25 days of composting. The analysis was performed with the GLM procedure (SAS, 2009) and the Tukey test. The inoculum had no effect on the composting of the substrates investigated. The PAC had the highest substrate temperature (30 ° C), although this is low compared to conventional composting which manure. After the substrates were overturned, the temperature increased only in PAEC. Compost PAC had a low content of organic matter and a more alkaline pH. It was concluded that it is feasible composting dead rabbit, but to optimize the process requires improving the conditions of composting to achieve a higher temperature and mineralization and reduce nitrogen loss by degradation of the protein of meat.
