Ammoniation of rice straw using poultry litter: Effect on nutrient composition and patholgenic microbial flora

Abstract

La valeur nutritive et la flore microbienne pathogene de la paille de riz traitee a la litiere de volaille dans un essai factoriel 5x3x3 a ete evaluee a l’Universite Abubakar Tafawa Balewa, a Bauchi, au Nigeria. La paille de riz a ete melangee avec la litiere de volaille (RSPL) dans cinq proportions differentes 5:5, 6:4, 7:3, 8:2 et 9:1. L’eau a ete melangee avec chacun des RSPL (1-5) dans trois proportions differentes, 50:50, 60:40 et 70:30, respectivement. Les melanges ont ete conserves dans des futs metalliques etanche pendant 7, 14 et 21 jours.. La masse microbienne par gramme (UFC/g) etait significativement (P facon significative (P The nutritive value and pathogenic microbial flora of poultry litter treated rice straw in a 5x3x3 factorial trial was conducted at the Abubakar Tafawa Balewa University, Bauchi, Nigeria. Rice straw was mixed with poultry litter (RSPL) in five different ratios; 5:5, 6:4, 7:3, 8:2 and 9:1. Water was mixed with each of the RSPL (1-5) in three different proportions; 50:50, 60:40 and 70:30 respectively. The mixtures were kept in air-tight metal drums for treatment periods of 7, 14 and 21 days respectively. The colony forming unit per gram (CFU/g) was significantly (P while the CF and CFU/g decreased with days of treatment. It may be concluded that treating rice straw with poultry litter can improve the nutritive value while at the same time reduce the pathogenic microorganisms of the treated straw. An equal proportion of crop residue to poultry litter with an equal amount of water is required to enhance treatment. Treatment period of 21 days is required for effective treatment making the material safe for feeding to livestoc.
