Accomplishments

Objectives:

Identify measures of animal stress and well-being and characterize factors affecting the biology of stress and immune responses
Identify and assess genetic components of animal stress and well-being
Development of management strategies and/or tools to enhance farm animal well-being under conditions of climatic change or other stressful environment
Station(s): Virginia Tech (VT)

The overall objective of our research is to identify hypothalamic neuronal pathways that are involved in the appetite response to nutritional and thermal stressors in chickens, with an emphasis on broilers. We have developed a model in which chicks are delayed access to feed and transiently exposed to elevated or reduced temperatures in the brooder. The goal is to elucidate epigenetic mechanisms that regulate gene expression during this time, leading to persistent changes in feeding behavior that affect long-term growth performance and well-being.

Targeted Objectives: 1,2,3

Station(s): University of Virgin Islands (UVI)

Our projects evaluate stress on livestock, sheep and cattle, in a tropical environment.

Targeted Objectives: 1,2,3

Station(s): University of Kentucky

Equine athletes under heavy exercise need to be called out quickly. Traditional method for cooling horses is to drench the horses with cool water until physiological responses return to normal range. This study looks to combine drenching with airspeed provided by a fan to increase the rate of cool out. Unfortunately, the industry is looking at misting tents at many of the higher-level equine competitions for hot humid climates. The misting tent drops air temperature while increasing humidity which reduces evaporation effectiveness and maybe a concern with cool out potential. This study aims to provide an alternative option for improving cool out under these hot humid conditions.

Objectives 1,2.

Station(s): Tarleton State University (TSU)

We aim to better understand the physiology of dairy cattle (Cows and calves) under heat stress condition and to apply this knowledge for finding practical solutions within current housing and management strategies among Texas dairies.

Station(s): University of Nebraska, Lincoln (UNL) and University of Arizona (UofA)

The overall objective of our research team is to further elucidate the impact of stressors including heat stress, β-adrenergic agonist (βAA) supplementation, and the combination thereof, on ruminant livestock. To this end, we are examining genomic, physiological, and production (quality and quantity) measures of the response of livestock to these treatments. As an outcome, we will produce rigorous scientific data to serve as a basis upon which to develop new strategies to increase the efficiency of livestock production.

Objectives: 1,2,3

Station(s): University of Puerto Rico (UPR)

Thermal stress is responsible of the reduction in nutritional and reproductive performance of small ruminants in tropical climates. It is necessary to evaluate feeding strategies to enhance lamb production and characterize reproductive performance of sheep raised under heat stress.

Objectives: 1,3

Station(s): University of Wisconsin-Madison (UWM)

Thermal stress is responsible of the reduction in nutritional and reproductive performance of small ruminants in tropical climates. It is necessary to evaluate feeding strategies to enhance lamb production and characterize reproductive performance of sheep raised under heat stress.

Objectives: 3

Station(s): University of California-Davis (UCD) and AgResearch of New Zealand (NZ)

The overall objective for our groups is to create, validate, and refine behavioral toolsets for their use as biomarkers for stress and immune resilience. These behavioral toolsets are used in conjunction with immunological and physiological biomarkers of acute and chronic stress to evaluate and modify animal management and housing strategies.Objectives: 3

Station(s): Kansas State University and University of Nebraska, Lincoln (KSU-UNL)

Others collaborating with K-State: Provimi-Cargill, Texas Tech University,

K-State’s specific research objective is to develop novel and refine existing behavioral, physiological, and immunological biomarkers to for rapid identification of animals (on a per animal basis) that are in clinical and subclinical states of distress, injury, and sickness. These measures can help stakeholders make timely decisions for managing severe or chronic stressors among farm animals.

Objectives: 1,3

Accomplishments

VT: Student-development (Y. Xao, G. Wang, L. Liu, J. Yi, B. McConn, J. Wang); Peer-reviewed publications, completed animal work; started molecular analyses; Applied for 5 Grants (4 Denied, 1 Pending)

KY: Completed Horse response and physiological analyses. One Master’s Student completed thesis. Collected all data for heat stress abatement in Dairy cattle.

TSU: Submitted publication for calf heat stress experiments.

UNL-UofA: Conducted live-animal study of the effects of β1AA supplementation and heat stress on market lambs with focus on alteration in adipose tissue and cardiac function as well as the microbial community. Data analyses underway and some results will be presented at the Western section ASAS meeting in June. Coordinated study with University of Arizona researchers on heat stress and β2AA supplementation in beef cattle to be conducted July - Aug 2019.,

UPR: Performance of growing lambs in feedlot conditions fed TMR with two energy levels under stress was conducted. The effect of the season on ram semen quality have been determined Feeding strategies for ewes and lambs raised under heat stress have been evaluated.

UWM: Animal work on 2 research projects and preliminary analysis were conducted. We began animal work on 1 new project. Four abstracts were presented at American Dairy Science Association annual meeting (2019). Many extension presentation were provided at producer/industry meetings. In addition, I applied for and gained USDA-NIFA funding for 1 project

UCD-NZ: We published scientific, peer reviewed manuscripts centered on Dairy Cattle and Heat stress. We analyzed existing data sets for drool as an additional indicator of heat stress in cattle.

KSU-UNL-PC-TTU: Several peer-reviewed publications were accomplished. Two grant proposals were submitted and one was funded. Two M.S. Students completed their theses and one undergraduate researcher from K-State accepted a position with USDA-ARS at Purdue (D. Lay).

Impacts

VT: These efforts have contributed to our understanding of how early post-hatch nutritional and thermal stressors affect feeding behavior, thereby affecting growth and well-being of the chicken.
UVI: The greater lag time for maximum VT of STX ewes may be a part of their adaptation to the tropical climate and the STX ewes may have a lower sensitivity to environmental temperature than the DRPX ewes.
KY: Student development, 2 proceedings, 1 abstract, 1 poster presentation
TSU: Three abstracts were presented at scientific meetings and one M.S. student completed her thesis (S.E. McGill, Student of B. Jones).
UNL-UofA: There are no indications that β1AA and heat interact to decrease wellbeing or performance. However, heat itself caused increased circulating white blood cells and cardiac hypertrophy; the latter of which was improved by β1AA. Because of this work, MS student theses and undergraduate researchers will gain animal and lab experience through this collaboration between UAZ and UNL. Moving our lamb model to beef cattle we will generate data to address goals of our main objective. Also, we gained recognition from this work: Two Western Section of ASAS Young Scholar awards were granted to C. Cadaret and R. Posont, D. Yate’s students.
UPR: Appropriate feeding and management of sheep raised under heat stress, improved productive and reproductive performance as evidenced by lambs growing parameters, ram semen quality and ewe productivity. We also found that semen quality of rams raised under heat stress is influenced by season of the year. Our results indicate great impact on performance of finished crossbred lambs fed TMR with energy levels higher than recommended. In addition, pre-wean lambs raised under heat stress conditions with access to creep-feeding with a high protein level concentrate enhanced its growing and health parameters. Student have advanced their careers because of this work: 1) J. Suarez , MS student working in the project, was accepted in the Veterinary Medicine College at Louisiana State University; 2) M. Rodríguez , undergraduate student working in the project, was accepted in the Veterinary Medicine College at Penn State University.
UWM: These multistate efforts quantified the effectiveness of providing heat abatement in both conventional and unconventional locations on a dairy facility using cows' physiological and behavioral indicators of heat stress.
UCD-NZ: Overall impact is the refinement of additional measures for assessing heat stress in dairy cattle. Also, two student’s careers progressed because of these efforts (A. Druenk of NZ and G. Tresoldi of UCD)
KSU-UNL: Overall, the impact the work has: strengthened our knowledge about the physiological underpinnings of behaviors during stress; increased management of novel technologies, and, we gained knowledge about how stress mitigation strategies can be applied to improve efficiency. In addition, two Latin-X students advanced their careers and one undergraduate gained a graduate position because of multistate efforts. At K-State, one professor became the director of the Dairy Cattle Reproduction Council (DCRC)
