EFFECT OF USING A NEW AUTOMATIC HEATING SYSTEM POWERED BY RENEWABLE ENERGY ON POULTRY HOUSES

Abstract

A new automatic simple heating technique was established to improve performance within poultry houses using renewable energy sources (Biogas energy). Four different heating systems were used in the work as follow: H.S 1 ; Conventional heating system using the cylinder of Liquefied Petroleum Gas LPG with open direct fire flame. H.S 2 ; Heating system using Biogas energy and the cylinder of LPG with open direct fire flame manual converting. H.S 3 ; Heating system using the cylinder of LPG with the automatic manufacturing heater and air distribution perforating tube. H.S 4 ; Heating system using Biogas energy and the cylinder of LPG with the automatic manufacturing heater and air distribution tube. The obtained results revealed that using Biogas increase poultry body weight/bird after 6 weeks by about 3%, and by about 4% approximately in total body weights, and increase production efficiency factor (PEF) by about 10.3% compared to conventional system. Also, applying H.S 4 increase poultry body weight/bird about 175 and 163% after first and second week respectively compared with the initial stage. In addition, increase the poultry weight/bird after 6 weeks by about 30%. Applying new system, also increase feed intake ranging about 6-8%, and decrease Feed conservation ratio ranging 29-33%. Applying a new system and using biogas increasing the survival ratio by about 6%, sequent decrease mortality rate. In addition, increase PEF by about 85% comparing with conventional. Applying H.S 4 the total energy decreased by about 53%, Also the specific energy requirements (SER) highly improving where decreased by about 66% comparing with H.S 1 .
