Goals / Objectives
Identify measures of animal stress and well-being and characterize factors affecting the biology of stress and immune responses Development of management strategies and/or tools to enhance farm animal well-being under conditions of climatic change or other stressful environments.
Project Methods
Methods are observational of environment and other condtions and do not require direct measures on farm animals.For both objectives listed above, typical field demonstration and research methodswill be employed to gather environment (air quality) and animal paramenters. Projects typically employ off-the-shelf instrumentation with setup that assures high-quality on-farm measurements. Information will be diseminated through Penn State Extension's animal welfare initiative and other means within that team.Evaluation via informal survey of changes in management that reflect increased awareness of how to reduce farm animal stressors will be conducted.

What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Objective 1. Chicken respiratory health and growth parameters were studied in relation to aerial environment challenges with our development of new sensor technology to monitor the bird environment. The project team developed dataloggers with integrated sensors to record room temperature, relative humidity, light intensity, room exhaust air speed, carbon dioxide concentration, ammonia concentration, and airborne dust concentration. Dataloggers automatically controlled ammonia and dust generation based on sensor feedback for three sets of environmental conditions including control conditions with no added ammonia or dust. The ammonia gas generator can automatically maintain a concentration of 50 ppm (or other setpoint) and the dust generator that dispersed poultry house particulate matter into the air to maintain a desired concentration. Instrumentation system can be used in future growth chamber lab experiments to evaluate animal welfare related to aerial contaminant levels found in commercial poultry production. Objective 2. A carbon-cycle featuring concept and technical aspects of methane and other farm-based climate change topics will be incorporated into the Dairy Virtual Farm for sustainability. Funding sub-contract is in place for development starting in early 2022. Improved ventilation systems for floor-raised cage-free hen housing provide not only comfortable conditions at hen level but also reduce potential for disease spread within buildings. Practical ventilation recommendations were documented, which have been and will continue to be provided to egg producers and poultry house builders. A completed study, and follow-up funding, simulates the flow of air and particles to quantify the effectiveness of ventilation systems using a computational fluid dynamics (CFD). Of interest is that mid-wall alternative inlet designs in combination with the vertical roof-level exhaust were able to limit most disease contamination to the half of the hen house were the vector was introduced. This Egg Industry Center supported study has been successful in attracting additional funding for more complicated CFD modeling. Results will address practical issues related to indoor air quality of agricultural buildings in the future.

Impacts
What was accomplished under these goals? Objective 1. The biological effects of airborne dust and ammonia gas on chicken respiratory health and growth parameters is being studied along with development of new sensor technology to monitor the bird environment. The project team developed dataloggers with integrated sensors to record room temperature, relative humidity, light intensity, room exhaust air speed, carbon dioxide concentration, ammonia concentration, and airborne dust concentration. Dataloggers automatically controlled ammonia and dust generation based on sensor feedback for three sets of environmental conditions including control conditions with no added ammonia or dust. The ammonia gas generator can automatically maintain a concentration of 50 ppm (or other setpoint) and the dust generator that dispersed poultry house particulate matter into the air to maintain a desired concentration. Instrumentation system concept can be used in this and future growth chamber lab experiments to evaluate animal welfare related to aerial contaminant levels found in commercial poultry production. (Hofstetter primary; Fabian support role) Objective 2. A completed two-year study offers improved ventilation systems for floor-raised cage-free hen housing. The improvements provide not only comfortable conditions at hen level but also reduce potential for disease spread within buildings. Practical ventilation recommendations were documented, which have been and will continue to be provided to egg producers and poultry house builders. The study simulates the flow of air and particles to quantify the effectiveness of ventilation systems by using a well-established engineering computer modeling technique computational fluid dynamics (CFD). Four three-dimensional CFD models analyzed a full-scale floor-raised hen house with the standard top-wall inlet sidewall exhaust ventilation system and three alternatives using mid-wall inlets with exhaust at the roof level. One-eighth of a real commercial hen house was modelled although the reduced size included a representative number of hens, ventilation inlet and fan features and portions of a barn important for hen management, for example nest boxes, feed and water area and litter scratch floors. Over two-thousand individual birds were modeled with simplified but realistic shapes. Particles of ammonia were introduced to the hen house at the upwind ventilation inlets to represent a contaminant, such as virus. The contaminant dispersion through the house and outdoor environment was simulated by comparing their outputs at locations represented by cross-sectional planes in the model at a ventilation rate suitable for cold weather (0 degrees C). Five animal-occupied zones within each of the model planes were evaluated for practical hen comfort attributes, air velocity and temperature, and ventilation performance, static pressure difference and presence of the contaminant mass fraction. Results indicated the three alternative models showed comparable performance in maintaining desirable microclimate at the bird level, compared to the standard ventilation model. The temperature at the bird level was maintained atacceptable 20 to 24 degrees C on average by all models. The indoor static pressure was stabilized at -25 to -21 Pa, which fell in the normal range for a hen house with the negative-pressure ventilation. Simulation results also revealed the standard ventilation model and two of the alternative models had indistinguishable performance in containing the contaminant, while the average contaminant level in mid-wall inlet design with a ceiling duct exhaust was 19% lower than the others within the majority of the indoor space. Of interest is that the mid-wall alternative inlet designs in combination with the vertical roof-level exhaust were able to limit most contamination to the half of the hen house where the vector was introduced. This Egg Industry Center supported study was part of a completed Ph.D. dissertation that demonstrated CFD modeling was a powerful tool for studying ventilation systems for animal housing and for addressing practical issues related to indoor air quality of agricultural buildings in the future.

What do you plan to do during the next reporting period to accomplish the goals?Continue with develpment of Extension products and interactions with commercial farm community.

Impacts
What was accomplished under these goals? Goal 1. A project is underway to study the biological effects of airborne dust and ammonia gas on chicken respiratory health and growth parameters. Developed dataloggers with integrated sensors to record room temperature, relative humidity, light intensity, room exhaust air speed, carbon dioxide concentration, ammonia concentration, and airborne dust concentration. Dataloggers automatically controlled ammonia and dust generation based on sensor feedback for two sets of environmental conditions and control conditions with no added ammonia or dust. The ammonia gas generator can automatically maintain a concentration of 50 ppm (or other setpoint) and the dust generator that dispersed poultry house particulate matter into the air to maintain a desired concentration. Instrumentation system concept can be used in this and future growth chamber lab experiments to evaluate animal welfare related to aerial contaminant levels found in commercial poultry production. Goal 2. A study funded by the national Egg Industry Center evaluated ventilation system designs in floor-raised cage-free hen housing for maintaining suitable, comfortable conditions at hen level while also evaluating the potential for disease spread within those buildings. The study used a well-established engineering computer modeling technique computational fluid dynamics (CFD) that simulates the flow of air and particles to quantify the effectiveness of ventilation systems. Four three-dimensional CFD models were developed of a full-scale floor-raised hen house, corresponding to ventilation configurations of the standard top-wall inlet sidewall exhaust and three alternatives using mid-wall inlets with exhaust at the roof level. In addition, 2,365 birds were individually modeled with realistic but simplified shapes. One-eighth of a real commercial hen house was modelled although the reduced size included a representative number of hens, ventilation inlet and fan features and portions of a barn important for hen management, for example nest boxes, feed and water area and litter scratch floors. A surrogate virus contaminant, particles of ammonia, were introduced to the hen house at the upwind ventilation inlets and their dispersion through the house and outdoor environment was simulated. Performance of the standard ventilation configuration and alternative designs were analyzed and evaluated by comparing their simulation outputs at locations represented by cross-sectional planes in the model. The simulated ventilation rate for the hen house in each model fell in the desired range for cold weather (0 degrees C). Five animal-occupied zones within each of the model planes were evaluated for practical hen comfort attributes, air velocity and temperature, and ventilation performance, static pressure difference and presence of the contaminant mass fraction. Results indicated the three alternative models showed comparable performance in maintaining desirable microclimate at the bird level, compared to the standard ventilation model. The temperature at the bird level was maintained between 20 and 24 degrees C on average by all models, which was acceptable in the cold weather. The indoor static pressure was stabilized at -25 to -21 Pa, which fell in the normal range for a hen house with the negative-pressure ventilation. Simulation results also revealed the standard ventilation model and two of the alternative models had indistinguishable performance in containing the contaminant, while the average contaminant level in mid-wall inlet design with a ceiling duct exhaust was 19% lower than the others within the majority of the indoor space. Of interest is that the mid-wall alternative inlet designs in combination with the vertical roof-level exhaust were able to limit most contamination to that half of the hen house were the vector was introduced. Considerable simulation results and subsequent analyses substantially demonstrated these alternative models had the capacity to create satisfactory indoor conditions for the cage-free hen house. Practical ventilation recommendations are documented based on simulation output, which have been and will continue to be provided to egg producers and poultry house builders. This study was part of a completed Ph.D. dissertation and demonstrated that CFD modeling was a powerful tool for studying ventilation systems for animal housing and for addressing practical issues related to indoor air quality of agricultural buildings in the future.

Impacts
What was accomplished under these goals? Goal 1: No thing to report for this reporting period. Goal 2: Virtual Dairy Farm. virtualfarm.psu.edu. Primary achievements of the website: 1. A virtual tour of a modern dairy farm providing major aspects of milk production. 2. Understanding climate change within the context of sustainability and environment. 3. Offering science-based dairy content at various technical levels appropriate for multiple audiences. The layered structure offers a place for interrelated topics at the user's level of interest: from simple information of interest to the public through technical bulletins aimed at dairy producers and their professional advisors to actual research data and models. Site development was a collaboration of multiple university faculty/staff and industry professionals of various disciplines, but primarily from agricultural engineering perspectives. Having sustainability information accessible on one site is valuable to dairy industry partners who have expressed frustration with figuring out who has the information they are seeking. Dairy gypsum-bedding material and manure gas emissions. Unfortunately, several human and cattle deaths were associated with manure storage agitation events on farms using gypsum bedding. Farmers use gypsum as stall bedding for its agronomic benefits, once land-applied with the manure, along with cow health and welfare in the barn. A series of research and demonstration projects documented potentially hazardous conditions associated with a routine farm management practice. Dangerous levels of hydrogen sulfide gas were released during agitation of dairy manure storages when gypsum bedding was present; this was not the case when no gypsum bedding was used. Projects documented the gas levels then created Extension education materials, media releases, on-line information, and events to inform the agricultural community on a national level. Manure additive products were identified to mitigate the gas release from stored dairy manure with gypsum bedding. Increased awareness from our projects and education has resulted in enhanced safety around manure handling and an appreciation for how to reduce potential dangers from gypsum bedding use.

What do you plan to do during the next reporting period to accomplish the goals?Continue development of internet based virtual farm for dairy system sustainability

Impacts
What was accomplished under these goals? The dairy farming community faces challenges from extreme weather events and changing environments related to climate change. There is a need to understand the complex interactions of not only climate issues but also maintain or improve economic viability and the dairy industry's continuing commitment to sustainability. On-farm decision making and policy can be improved with access to science-based information on greenhouse gases, mitigation strategies and related production sustainability issues. Farmers can find climate change and sustainability principles in action thanks to an interactive "virtual farm" web site developed by Penn State Extension in partnership with Penn State's WPSU design team, the University of Wisconsin-Madison and the Dairy Innovation Center. The objective is to provide a 'one-stop shop' for all dairy sustainability information. The website opens with a visual tour of a dairy farm with embedded resources. Users can click on various aspects of two farm scales: 150 or 1500 milking cows. Exploration of features, such as housing, manure storage and fields, provide simple information immediately while allowing for deeper exploration of each topic depending on user interest. The site's database contains a broad range of articles, extension fact sheets, images and model data. Sustainability topics focus on milk production, herd and nutrient management, crops and soils and greenhouse gases. The website is national in scope although focused on dairy systems typical of the Great Lakes region of North America. Feedback has been complimentary regarding content and usefulness of the website. Users note the high quality layout and streamlined interaction for learning and finding information. The primary appreciation notes the layers of information ranging from simply "looking and learning" followed by user-friendly extension materials to highly technical peer-reviewed articles and research data. Science based information is found at all levels yet users do feel not "blinded by science" beyond their level of interest in a topic. Farmers interacting with the site noted its benefit for employee training. The site is being cloned for use by other farm types to organize similar sustainability information. Graduate student projects at other universities are developing site information for related topic areas. Industry leaders are adding additional resources so the site continues to grow as a "one stop" for dairy sustainability information.
