Effects of Laying Hen Manure Application Rate on Water Quality
Excessive use of animal manure on agricultural lands can impact the quality of surface and groundwater resources. A three–year study (1998–2000) was conducted on nine 0.4–ha plots and on six 2.1–m 2 lysimeters to investigate the effect of two nitrogen (N) application rates from laying hen manure and one N application rate from urea ammonium nitrate (UAN) fertilizer on surface and groundwater qu...
متن کاملEffects of Corn Distillers Dried Grains on the Performance and Egg Quality of Laying Hen
A study was conducted to determine the effects of corn distillers’ dried grain (CDDG) on the performance and egg quality of laying hens. The hens were fed dietary inclusions of CDDG at 0, 10, 20, 30 and 40% for a period of eight weeks. Average feed intake, weight gain, feed conversion ratio and nitrogen economy varied significantly (P<0.05) among dietary treatments. Birds fed 30% dietary CDDG h...
متن کاملEffects of Dietary Modifications on Laying Hens in High-Rise Houses: Part II—Hen Production Performance
Dietary manipulation can substantially lower ammonia emissions from laying hen manure. However, such dietary changes would be of little value if the changes cause inferior egg production and hen performance. Therefore, the objective of this study was to evaluate the effect of a diet containing EcoCalTM (gypsum and zeolite), which has been shown to lower ammonia emission in laboratory-scale test...
متن کاملEffect of Different Levels of Germinated Barley on Performance and Egg Quality in Laying Hen
Objective: The experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. Methods: One hundred and twenty laying hens, 44-weeks old, Lohmann LSL hens were used in this experiment. Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment w...
