Accomplishments

Kifle Gebremedhin, NY

Heat stress is a challenge facing the dairy industry. It is estimated to cause a 4-7% revenue loss per year for the $36-billion US dairy industry. Thermal stress imposed on cows adversely affects health and productivity. We developed models that predict thermal stress levels of dairy cattle, and design cooling systems to alleviate thermal stress. Conductive cooling for dairy cattle is an emerging technology that holds promise as a way of relieving heat stress. Waterbeds were placed in stalls of dairy cows to serve as heat exchangers between the cows and the water in the waterbeds.

Overall Impact:  A novel conductive cooling system for dairy cows was developed. The cooling system increased milk yield by 5%, dry matter intake by 14%, decreased rectal temperature by 1.0°C and respiration rate by 18 breaths/min. Thus, conductive cooling may be a useful tool to alleviate heat stress in dairy cows. To avoid moisture condensation in the bedding of these systems, the bedding thickness should exceed 2.5 cm. The predictive performance of the model was better than models existing in the literature with respect to predicting skin temperature, respiration rate, and core-body temperature.

Water restriction has been used in the weaning process when lambs were weaned at 60 days of age in an accelerated lambing system to help dry up milk production of the ewe.  Now that weaning is being done at 120 days of age we evaluated the effect of water restriction during weaning on St. Croix White ewes and lambs. To further characterize traits that help to make local livestock adapted to the tropical environment, the relationship between body temperature, and ambient temperature was evaluated in Senepol and crossbred heifers, and in St Croix White and Dorper X St Croix White ewes.

We created protocols for an in-pen approach tests to distinguish sub clinically injured pigs from sham-treated pigs.  In addition, we developed a standard protocol for conditioning pigs to be able to test cortical  function through somatosentory  stimulation. These protocol swill be published in a peer-reviewed journal during the next performance period. In addition, we tested the efficacy and the stress-responses on sows subjected to of a commercially available technology that uses aversive stimuli (vibration and electric  impulse) to cause a sow to stand when sensors and artificial intelligent programming detect a piglet during crushing. We found that although treated sows show behavioral signs of distress in the seconds after the stimulus, their overall behaviors and circadian cortisol were less disrupted than sows that were convent ally stimulated (hand-slap to hind quarters).

 We also developed validated an automated environmental enrichment device for boars that they continuously use (especially in evenings and mornings). We will further test in the next period if this automated information can be used to distinguish sub clinically injured pigs from healthy pigs. Following that development, we will work with NE and WI to test the devices on commercial boars and determine if this information will be a useful predictor for semen quality.  (PI: Hulbert)

Our projects are focused on addressing welfare concerns for food producing animals in three significant areas: 1) instances in which animals may experience pain or distress, 2) morbidity or mortality, and 3) the deleterious effects caused by climate variability. Results from the research directly address the public’s concerns relative to animal welfare which are being raised across the United States and globally. 

Overall Impact:  Weaned and transported pigs are inherently stressed by these procedures which are unavoidable. An experiment to determine the threshold for efficacy of L-glutamine as an antibiotic alternative for swine producers following weaning and transport was conducted.

It was determined that a range between 0.40 and 0.50% was the level at which L-glutamine would provide a maximal positive effect on swine welfare and productivity. In addition, this finding has further refined and built upon previous work in which it was found that 0.20% L-glutamine was also effective.

This project investigates the development of tail biting in pigs through monitoring activity changes. The hypothesis is that changes in activity levels may be an indicator of outbreaks of tail biting in pigs, and activities in pigs could be monitored by an optical flow platform.

Overall Impact:  Swine producers may predict outbreak of tail biting by monitoring changes in activity levels of pigs. Prediction of tail biting outbreaks will give pig producers opportunities to implement management strategies to prevent the outbreak.        

Impacts

  1. Objective 1 Dairy: A model that predicts level of heat stress imposed on cattle was developed. The model links environmental stressors and physiological responses of cows. (PI: Kifle Gebremedhin)
  2. Objective 1 Dairy: Water condensation in bedding should be a design consideration when conductive cooling systems are installed in dairy barns. (PI: Kifle Gebremedhin)
  3. Objective 1 Dairy: Published in the Journal of Animal Science evidence that susceptible cows affected by heat stress may be identified at the farm-level (PI: Mendonca)
  4. Objective 1 Swine: A machine learning algorithm was trained to predict rectal temperature, skin-surface temperature and hair-coat surface temperature of piglets based on environmental data. (PI: Kifle Gebremedhin)
  5. Objective 1 Swine: The study demonstrated that pigs had higher optical flow during the first outbreak of tail biting compared to before and after the outbreak, and during outbreaks after the first, suggesting activity changes during the development of tail biting outbreaks. In general, pigs had lower optical flow at noon compared to morning and afternoon, suggesting that pigs were less active at noon which was supported by the data of behavioral time budget. These results suggest that optical flow might be a promising tool for monitoring activity changes in pigs during the development of tail biting.
  6. Objective 1 Sheep: Analyses were completed on genomic, physiological, and performace data from our 2016-2017 live animal heat stress/βAA trial (N=49). Data include RNA-seq on skeletal muscle and liver, microbiome sequencing, skeletal muscle metabolic studies and fiber analyses, blood plasma analyses, animal performance, and carcass characteristics. (PI: Petersen, Yates, Schmidt)
  7. Objective 1 Sheep: Data are being disseminated and used for hypothesis building. Students presented data from this project at the Western Section meeting of the ASAS and in departmental seminars. Three theses defensed have been successfully completed. Data were also presented in an invited talk and the overall project featured in a Departmental publication. (PI: Petersen, Yates, Schmidt)
  8. Objective 1 Sheep: A digital method (cameras) for measuring respiration rate was validated. This method will be employed for future studies of heat stress. (PI: Schmidt, Petersen, Yates)
  9. Objective 2 Sheep: Analyses were completed on genomic, physiological, and performance data from our 2016-2017 live animal heat stress/βAA trial (N=49). Data include RNA-seq on skeletal muscle and liver, microbiome sequencing, skeletal muscle metabolic studies and fiber analyses, blood plasma analyses, animal performance, and carcass characteristics. (PI: Petersen, Yates, Schmidt)
  10. Objective 2 Sheep: Data are being disseminated and used for hypothesis building. Students presented data from this project at the Western Section meeting of the ASAS and in departmental seminars. Three theses defensed have been successfully completed. Data were also presented in an invited talk and the overall project featured in a Departmental publication. (PI: Petersen, Yates, Schmidt)
  11. Objective 3 Dairy: Extension publication to demonstrate to dairy farmers that reproductive efficiency during the summer may be improved by mitigating heat stress (heat abatement in the parlor) (PI: Mendonca)
  12. Objective 3 Dairy: Extension publication to show evidence that herd reproductive efficiency and postpartum herd health during the summer are associated (PI: Mendonca)
  13. Objective 3 Dairy: Tested and published results about the effects of different flow rates and timing intervals on cattle behavior and physiology (PI: Tucker, Schutz)
  14. Objective 3 Dairy: Contributed to a new heat-load index (PI: Gebremedhin, Tucker)
  15. Objective 3 Dairy: Determined appropriate weaning strategies for calves fed higher planes of nutrition during the preweaning phase using behavior, and digestibility. (PI: Hulbert)
  16. Objective 3 Swine: Demonstrated that short-term dietary modification can have long-lasting effects on behavior, cognition and welfare in pigs. Pigs fed a synbiotic or L-glutamine coped better with stressful events and had cognitive advantages, being better able to perform a variety of behavioral tests. (PI: Marchant-Forde)
  17. Objective 3 Swine: The study demonstrated that pigs had higher optical flow during the first outbreak of tail biting compared to before and after the outbreak, and during outbreaks after the first, suggesting activity changes during the development of tail biting outbreaks. In general, pigs had lower optical flow at noon compared to morning and afternoon, suggesting that pigs were less active at noon which was supported by the data of behavioral time budget. These results suggest that optical flow might be a promising tool for monitoring activity changes in pigs during the development of tail biting. (PI: Marchant-Forde)
  18. Objective 3 Poultry: Developed an equation to predict core body temperature from facial skin temperature in broiler chickens using infrared thermography (PI: Johnson)
  19. Tested the feasibility of cooling perches in laying hen cages to help hens cope with heat stress. Based on the results collected from the heat stress study, the perches of the enriched (or furnished) cages can be modified as a thermal cooled device (10 C cooled water circulated through the perch system) to prevent or reduce heat stress effects in laying hens. (PI: Cheng)
  20. Objective 3 Sheep: These data show that hair sheep in the tropics do not exhibit signs of dehydration, based on hematocrits, from water deprivation during a 48-h weaning process. Water deprivation only slightly decreased udder volume which may help to manage udder health. Future studies will be done to evaluate breed comparisons (St. Croix White vs Dorper x St. Croix White) (PI: Bob Godfrey, Sue Lakos, Serena Joseph)
  21. Objective 3 Sheep: The greater lag time for maximum vaginal temperature of St Croix White ewes may be a part of their adaptation to the tropical climate. (PI: Bob Godfrey, Sue Lakos)
  22. Objective 3 Sheep: A digital method (cameras) for measuring respiration rate was validated. This method will be employed for future studies of heat stress. (PI: Schmidt, Petersen, Yates)
