A rainfall simulation study was conducted to determine the effects of spring-applied dairy cow () manure (none, in-barn composted, and exterior walled-enclosure pit) with >200 g kg organic solids content following fall corn biomass removal with and without incorporation (chisel plow [CP] and ...
[114] reported the inactivation and reduction of pathogenic microbes, such asE. coliandSalmonella enterica, by BSFL in poultry manure. Similar results were observed for dairy cow manure substrate, as BSFL significantly reduced the population ofE. coli. In both studies, temperature significantly ...
(50, 100 and 200m 3 ha 1 y 1 ) of pig and cow slurries on yield, botanical composition and nutrient content of herbage of an original perennial ryegrass sward were assessed in a three-cut silage system and compared with unamended and fertilized controls in the 36th year of the ...
Use of magnesium hydroxide and calcium compounds with and without a carrier medium to treat animal waste: to reduce air emissions (including ammonia volatilization) from, retain nutrients from, and manage phosphorous solubility of decayi... A method for treating CAFO animal litter, manure and waste...
LO Tedeschi,DG Fox,JB Russell - 《Journal of Animal Science》 被引量: 132发表: 2000年 The effects of ruminally degraded protein on rumen fermentation and ammonia losses from manure in dairy cows This experiment investigated the effect of dietary crude protein (CP) and ruminally degraded protein...
Optimizing feed composition for improved methane yield during anaerobic digestion of cow manure based waste mixtures. This study investigated methane yield via anaerobic digestion of multi-component substrates based on mixtures of biodegradable single-component substrates ......
(liquid cow manure: 80 Mg/ha/year) or inorganic fertilizers (260 kg N ha/year and 57 kg P/ha/year) (six plots each). Fertilizers were incorporated into the soil with a disk harrow (12–15 cm depth) within two hours of application. Grain yield was measured in two rows (12.8 m2) ...
2. A process according to claim 1, wherein the treated site is litter or liquid manure. 3. A process according to claim 1, wherein the treated site is a floor or building. 4. A process according to claim 1, wherein the treated site is a building for the commercial rearing of animal...
This experiment was conducted in order to determine the efficacy of a dye, bait, and adjuvant combination as a phototoxic insecticide for fly larvae. Three different formulas were tested in cow manure piles to determine their toxic efficacy. A first formula contained 4% Phloxine B mixed with de...
Urinary urea nitrogen losses were increased by HOLL, which, as a consequence, increased the ammonia-emitting potential of manure. The ratio of milk N-to-N intake was greater for CMEC and RPS. Replacing solvent-extracted canola meal with the high-oil meal decreased milk fat 12:0, 14:0, ...
