Evaluation of a Granulated Paper Waste Product as a Suitable Bedding Material for HorsesYoungblood, Amanda Arrington 12 May 2012 (has links)
Three 14 day trials were used to compare granulated paper(GP) to pine pellets(PP) and wood shavings(WS) as bedding for horses. During days 1 through 5 stalls were cleaned daily of feces only, and stalls were cleaned of both feces and saturated areas from days 6 to 14. For stall cleanliness, PP was cleaner than both GP and WS. Initial pH was greater for both GP and WS compared to PP. The water holding capacity for WS was greater than PP and GP. On day 5 there was ammonia detected for WS during trial 1. GP and WS emitted more ammonia than PP when air flow was restricted. Bacteria found in the nasal cavity were not different among bedding types. GP had more fungal growth. Minerals were found within the maximum tolerance of horses. Results indicate the use of GP as a bedding material for horses has potential.

EFFECT OF BEDDING TYPE AND SOIL INCORPORATION ON NITROGEN MINERALIZATION RATE OF BROILER LITTER AMENDED SOILSFitzgerald, Lydia A. 01 January 2019 (has links)
Broiler litter (BL) is a high value manure available to Kentucky crop producers to utilize as a fertilizer. The rate of BL application, timing of application, and method of application are all important factors to take into account when utilizing BL. A laboratory incubation was conducted to observe nitrogen (N) mineralization rates of BL amended soils over time under different conditions. Different application methods, application rates, watering frequencies, and bedding materials were used to determine their influence on N mineralization. Broiler litter applied on the soil surface, at lower rates, at lower watering frequency resulted in lower mineralization rates than BL that was incorporated, at higher rates and higher watering frequency. The rice hull bedding BL treatments had a significantly higher initial amount of NH4+-N than the wood-based bedding materials. The increased NH4+-N content produced a lower pH due to higher rates of nitrification. The difference in NH4+-N resulted in the rice hull BL treatments containing more inorganic N throughout the incubation. The wood-based BL contained significantly more carbon (C), zinc (Zn), and potassium (K). The results collected will help improve current nutrient recommendations and provide information that will help utilize BL more efficiently and economically.
