“…For three consecutive flocks, NaHSO 4 was applied at a rate of 0.24 kg/m 2 , with two re-applications being performed at 5 and 10 days. For the first three flocks, there was no significant difference in nitrogen and NH 4 + concentrations of the litter (Hunolt et al 2015); however, after the fourth flock, 42.5 g/kg of nitrogen was recorded in the treated litter, compared with 38.6 g/kg in the control litter (Hunolt et al 2015). Ammonium concentration of the treated litter was 15.3 g/kg after the fourth flock, which again was more than the 13.2 g/kg in the control (Hunolt et al 2015).…”

“…Ammonia volatilisation was observed at a 269% increase when manure remained untreated, as opposed to the test that utilised NaHSO 4 re-application (Hunolt et al 2015). Treated litter had a nitrogen concentration of 26.5 g/kg compared with 24.6 g/kg for untreated litter, indicating an increase in nitrogen retention (Hunolt et al 2015). A single initial application of NaHSO 4 resulted in NH 3 concentrations being significantly lower than in the control test (Hunolt et al 2015).…”

“…Initial NaHSO 4 application was applied at a rate of 0.48 kg/m 2 , with re-applications being at a rate of 0.24 kg/m 2 . Ammonia volatilisation was observed at a 269% increase when manure remained untreated, as opposed to the test that utilised NaHSO 4 re-application (Hunolt et al 2015).

“…Treated litter had a nitrogen concentration of 26.5 g/kg compared with 24.6 g/kg for untreated litter, indicating an increase in nitrogen retention (Hunolt et al 2015). A single initial application of NaHSO 4 resulted in NH 3 concentrations being significantly lower than in the control test (Hunolt et al 2015). These results suggested that a single application of NaHSO 4 could be enough to reduce NH 3 concentration; however, re-application would result in further reductions, but at an increased cost.…”

“…When applied to litter, NaHSO 4 dissociates to Na + , H + and SO 4-,with the hydrogen ion causing the pH in the litter to be reduced (Jones-Hamilton AG 2018). Hunolt et al (2015) conducted a controlled 14-day laboratory experiment and a field study using different strategies of NaHSO 4 application to reduce NH 3 volatilisation. Fresh manure was added every 48 h to simulate bird excretion.…”

Suitability of litter amendments for the Australian chicken meat industry

et al. 2020

The Australian chicken meat indutstry is rapidly expanding due to the increasing consumption of chicken meat. As a result, the industry has growing issues of sourcing new bedding materials and disposing of spent litter, which can be attributed, in part, to a lack of widespread litter re-use for rearing chickens. According to insights and perspectives recently gathered from industry stakeholders, it is believed that re-using litter will become more common in the future, so as to reduce production costs and ease pressures on both the supply of new bedding materials and disposal of spent litter. However, there are potential risks that need to be addressed if litter re-use increases, particularly with regard to the production and mitigation of ammonia, which can negatively affect chicken health if not managed correctly. The present review discusses the potential benefits reported for different types of litter amendments, which have the primary goal of reducing ammonia volatilisation, but may also contribute to improvements in bird performance, welfare, pathogen loads, fertiliser value of spent litter, and reduced costs associated with purchasing new bedding materials. Acidifiers have been shown to be the most effective of all amendment types, with sodium bisulfate or alum being among the most commonly tested products mentioned in research literature. Litter amendments are currently rarely used in Australia, but it is hoped that the information provided in the present review, based mostly on overseas usage and research, will help inform future decision-making on the use of these products in Australian poultry production systems.

Reused poultry litter microbiome with competitive exclusion potential against Salmonella Heidelberg

et al. 2020

The success of poultry litter reuse in U.S. poultry production can be attributed to the efficient treatment methods used by producers during downtimes (the time lapse between consecutive flocks, during which the broiler house is empty). During this period, reused litter may be decaked, tilled/windrowed, or treated with acid-based amendments to reduce ammonia and bacteria levels. Competitive exclusion, pH, and temperature are proposed factors that influence the level of pathogens and the overall litter microbiome during downtimes. We previously reported on the bacterial genetic factors associated with the fitness of two strains of Salmonella enterica serovar Heidelberg (SH) incubated for 14 d in reused litter. Here, we investigated the physicochemical parameters and the microbiome of the litter correlating with SH abundance during this period. We used 16S ribosomal RNA gene sequencing to determine the litter microbiome and whole genome sequencing to characterize bacteria with competitive exclusion potential against SH. The β diversity of the litter microbiome was significantly affected by the duration of incubation, microcosm, and microcosm plus Heidelberg strain combinations. In addition, β diversity was significantly affected by litter parameters, including NH 4 , pH, moisture, water activity, and aluminum. The major phyla observed in the reused litter throughout the 14-d incubation experiment were Firmicutes and Actinobacteria, although their abundance differed by microcosm and time. Amplicon-specific variants homologous to the members of the genera Nocardiopsis and Lentibacillus and the family Bacillaceae_2 were found to significantly correlate with the abundance of Salmonella. A consortium of Bacillus subtilis strains isolated from the litter microcosms reduced the growth of SH in vitro.

Succession patterns of the bacterial community in poultry litter after bird removal and sodium bisulfate application

Sulfate-based acid amendments are used for treating litter between broiler chicken flocks and during grow-out for in-house ammonia abatement. These amendments reduce litter pH and inhibit ammonia volatilization by converting ammonia to nonvolatile ammonium. Research on the effects of acid amendments on litter microbiota is limited and usually done in microcosms, which do not replicate natural environments. In this study, we determined the changes in bacterial populations present in litter during downtime (the period after a flock was removed and before new broiler chicks were placed) and 24 h before and after the application of a sodium bisulfate (NaHSO 4 )-based amendment. We used DNA sequencing technologies to characterize the litter microbiota, elucidating microbial shifts in litter samples with respect to downtime, litter depth, and NaHSO 4 application. During downtime (∼18 d), the litter microbiota was dominated by Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria. Sodium bisulfate affected the microbiota in the top layer (3 cm) of reused litter topdressed with fresh pine shavings and resulted in an increase in Escherichia spp. and Faecalibacterium spp. and a decrease in members of the phylum Acidobacteria. Furthermore, culturable Escherichia coli decreased by 1.5 log units during downtime, but an increase was observed for topdressed litter after NaHSO 4 was applied. Although the effect of acidifiers on ammonia reduction, bird performance, and litter performance are well documented, their effect on litter bacteria is not well understood. Our results suggest that acidifiers may perturb litter bacteria when topdressed with fresh pine shavings and that further research is required.
