Poultry litter amendments (LA) are commonly used to maintain good litter quality; the most common ones; are acidifiers. However, concern over the lifespan of LA acidifiers (d) and corrosive nature revealed a need for alternative LA. Products of interest include biochar (BC), superabsorbent polymers (SAPs), and alum mud (AM). Experiment 1 was a screening study (n=17 treatments, no birds) conducted to determine the optimal application rate/method of BC, SAPs, and AM vs.commercial LA and a control. Most SAPs treatments measured metrics may be similar (i.e., bacteria, water activity) or better (pH) vs. commercial LA (PLT). High inclusions of novel LA elicited the most litter quality benefit; therefore, were chosen for experiment 2 to determine their effects on 60 d litter quality and broiler performance and processing. Overall, novel LA improved litter quality parameters (i.e., moisture content, pH water activity) without negatively affecting live performance and processing parameters vs. control
