The Riverside County
“Planned Lay-out Program” was developed and later adopted by the county
to allow an additional 7 year period for poultrymen operating farms in
zones other than AP, to conform (acquire the AP designation) or phase
out their operations. This allowed an orderly transition with minimal
business disruption to the poultry industry while conforming to the
county’s General Plan.
The gross size and
structure of the bursa of Fabricius (a significant organ to the immune
system of the chicken) was characterized at different ages in male and
female single-comb white Leghorn chickens. This led to teaching flock
managers how to monitor bursal size in order to detect possible immune
impairment caused by infectious bursal disease virus infections in their
flocks.
Systematic mapping of
light intensity and temperatures in various types of poultry houses was
conducted over several years. These studies led to wide spread use of
fluorescent lighting systems and the use of house ventilation and design
systems that offer greater uniformity of temperature and air quality.
Was instrumental in the
development of the California Egg Quality Assurance Program (CEQAP); one
of the first of it’s type in animal agriculture in the United States.
This program is thought to have significantly contributed to the decline
in egg associated human outbreaks of Salmonella enteritidis in
California. The rapid containment of the last outbreak of Avian
Influenza and exotic Newcastle disease in California has been attributed
to the biosecurity measures adopted by the egg industry as a result of
the CEQAP.
Prior to and during the
recent outbreaks of Avian Influenza and exotic Newcastle disease,
biosecurity programs were developed for farms and egg processing plants
to minimize the likelihood of disease spread between farms. Teams of
veterinarians, managers and I walked through farms and processing plants
to evaluate and improve biosecurity practices in use by the industry.
Training workshops in biosecurity were also provided to all agency
personnel visiting poultry farms and plants throughout the state.
Over a period of 10
years several experiments and field studies were conducted to study
control strategies, chemical resistance and damage done to egg laying
flocks of chickens infested with northern fowl mites. New methods of
field monitoring, control strategies were developed. We demonstrated
and measured the economic damage of infestations and showed that beak
trimming of laying hens increased the dependence on chemicals as a
control strategy.
Several studies of
on-farm co-composting of chicken carcasses with manure produced on the
farm were conducted. Required composting time and temperature
relationships were determined for pathogen reduction and elimination.
Methods for safe and rapid burial of contaminated carcasses at landfills
were developed in the case of catastrophic die-off’s during emergencies. |
