Effect 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...
متن کاملAmmonia Emissions Rate from Composted Laying Hen Manure
During the past five years we have developed three emission calorimeters (EC) that can be used to evaluate mass generation and utilization of gasses. We have tested various treatments that significantly reduced ammonia generation by laying hen manure (Harrison and Koelkebeck, 2002; 2003). Disciplines Agriculture | Bioresource and Agricultural Engineering | Poultry or Avian Science Comments Post...
متن کاملEffects 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...
