Vocal Individuality And Species Divergence In The Contact Calls Of Banded Penguins, Livio Favaro, Claudia Gili, Cristiano Da Rugna, Guido Gnone, Chiara Fissore, Daniel Sanchez, Alan G. Mcelligott, Marco Gamba, Daniela Pessani

Alan G. McElligott, PhD

Penguins produce contact calls to maintain social relationships and group cohesion. Such vocalisations have recently been demonstrated to encode individual identity information in the African penguin. Using a source-filter theory approach, we investigated whether acoustic cues of individuality can also be found in other Spheniscus penguins and the acoustic features of contact calls have diverged within this genus. We recorded vocalisations from two ex-situ colonies of Humboldt penguin and Magellanic penguin (sympatric and potentially interbreeding in the wild) and one ex-situ group of African penguins (allopatric although capable of interbreeding with the other two species in captivity). We measured 14 …

Autonomic Nervous System Reactivity In A Free-Ranging Mammal: Effects Of Dominance Rank And Personality, Elodie F. Briefer, James A. Oxley, Alan G. Mcelligott

Alan G. McElligott, PhD

Modulation of the autonomic nervous system (ANS) activity allows animals to effectively respond to internal and external stimuli in everyday challenges via changes in, for example, heart and respiration rate. Various factors, ranging from social such as dominance rank to internal such as personality or affective states can impact animal physiology. Our knowledge of the combinatory effects of social and internal factors on ANS basal activity and reactivity, and of the importance that each factor has in determining physiological parameters, is limited, particularly in nonhuman, free-ranging animals. In this study, we tested the effects of dominance rank and personality (assessed …

Acoustic Divergence In The Rut Vocalizations Of Persian And European Fallow Deer, J. B. Stachowicz, E. Vannoni, B. J. Pitcher, Elodie F. Briefer, E. Geffen, A. G. Mcelligott

Alan G. McElligott, PhD

We conducted a study of the male rut vocalizations (groans) of two closely related species, Persian and European fallow deer. Persian fallow deer are endangered, restricted to Iran and Israel, and their rut vocalizations have never been studied. By contrast, European fallow deer are one of the most common deer species in the world, and have been the subject of numerous detailed studies. Persian bucks are approximately 16% larger than European bucks, and this can have important implications for vocalizations. Persian bucks were recorded in Israel, and European bucks were recorded in the UK and Ireland. We measured temporal, fundamental …

How Useful Is Gsv As An Environmental Observation Tool? An Analysis Of The Evidence So Far., Katherine Nesse, Leah Airt

SPU Works

Researchers in many disciplines have turned to Google Street View to replace pedestrian- or carbased in-person observation of streetscapes. It is most prevalent within the research literature on the relationship between neighborhood environments and public health but has been used as diverse as disaster recovery, ecology and wildlife habitat, and urban design. Evaluations of the tool have found that the results of GSV-based observation are similar to the results from in-person observation although the similarity depends on the type of characteristic being observed. Larger, permanent and discrete features showed more consistency between the two methods and smaller, transient and judgmental …

Exploring The Impact Of Olfaction On Short-Term And Long-Term Maternal Recognition In Peromyscus Californicus, Mariah F. Conley

Honors Projects

Previous studies have established a connection between social behavior and olfaction, in that as anosmia causes a decrease in perception of social cues, social behavior itself decreases. Studies investigating maternal behavior specifically have focused on foster care, in which the behaviors formed during parturition are conserved and displayed with unrelated pups. The combination of long-term retention of maternal behavior, maternal recognition, and olfaction has yet to be explored. In this study, I induced anosmia in Peromyscus californicus, a monogamous, biparental species, and analyzed their behavior with their own pups and with foreign pups in the days after birth, as well …

Investigation Of The Impact Of Increased Dietary Insoluble Fiber Through The Feeding Of Distillers Dried Grains With Solubles (Ddgs) On The Incidence And Severity Of Brachyspira-Associated Colitis In Pigs, Bailey Lauren Wilberts, Paulo Elias Arruda, Joann M. Kinyon, Timothy S. Frana, Chong Wang, Drew Robert Magstadt, Darin M. Madson, John F. Patience, Eric Ryan Burrough

Bailey (Wilberts) Arruda

Diet has been implicated as a major factor impacting clinical disease expression of swine dysentery and Brachyspira hyodysenteriae colonization. However, the impact of diet on novel pathogenic strongly beta-hemolytic Brachyspira spp. including “B. hampsonii” has yet to be investigated. In recent years, distillers dried grains with solubles (DDGS), a source of insoluble dietary fiber, has been increasingly included in diets of swine. A randomized complete block experiment was used to examine the effect of increased dietary fiber through the feeding of DDGS on the incidence of Brachyspira-associated colitis in pigs. One hundred 4-week-old pigs were divided …

Reduction In Activity By Noxious Chemical Stimulation Is Ameliorated By Immersion In Analgesic Drugs In Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Waleed Al-Nuaimy, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Research has recently demonstrated that larval zebrafish show similar molecular responses to nociception to those of adults. Our study explored whether unprotected larval zebrafish exhibited altered behaviour after exposure to noxious chemicals and screened a range of analgesic drugs to determine their efficacy to reduce these responses. This approach aimed to validate larval zebrafish as a reliable replacement for adults as well as providing a high-throughput means of analysing behavioural responses. Zebrafish at 5 days postfertilization were exposed to known noxious stimuli: acetic acid (0.01%, 0.1% and 0.25%) and citric acid (0.1%, 1% and 5%). The behavioural response of each …

Perception Of Emotional Valence In Horse Whinnies, Elodie Briefer, Roi Mandel, Anne-Laure Maigrot, Sabrina Briefer Freymond, Iris Bachmann, Edna Hillmann

Bioacoustics Collection

Background: Non-human animals often produce different types of vocalisations in negative and positive contexts (i.e. different valence), similar to humans, in which crying is associated with negative emotions and laughter is associated with positive ones. However, some types of vocalisations (e.g. contact calls, human speech) can be produced in both negative and positive contexts, and changes in valence are only accompanied by slight structural differences. Although such acoustically graded signals associated with opposite valence have been highlighted in some species, it is not known if conspecifics discriminate them, and if contagion of emotional valence occurs as a result. We tested …

Physiological And Behavioural Evaluation Of Common Anaesthesia Practices In The Rainbow Trout, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a widely-used model species with relevance to both aquaculture and natural ecosystems. This study sought to establish the relative acute impact of commonly used anaesthetics on rainbow trout when used for anaesthesia or euthanasia by exploring their effects on aversion behaviour and stress physiology. Five widely used anaesthetics were investigated at two concentrations reflective of common laboratory practises: MS-222, benzocaine, 2-phenoxyethanol, …

Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala

Animal Sentience

It is not possible to demonstrate that dogs (Canis familiaris) feel emotions, but the same is true for all other species, including our own. The issue must therefore be approached indirectly, using premises similar to those used with humans. Recent methodological advances in canine research reveal what dogs experience and what they derive from the emotions perceptible in others. Dogs attend to social cues, they respond appropriately to the valence of human and dog facial expressions and vocalizations of emotion, and their limbic reward regions respond to the odor of their caretakers. They behave differently according to the …

Route Of Mannheimia Haemolytica And Pasteurella Multocida Vaccine Administration Does Not Affect Health Or Performance Of Receiving Heifers, T. Spore, M. E. Corrigan, T. R. Parks, C. S. Weibert, M. L. Detray, W. R. Hollenbeck, R. N. Wahl, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Light weight stocker calves often experience health problems shortly after arrival to feeding facilities. Preventative health programs are routinely administered to calves upon arrival to reduce the incidence of Bovine Respiratory Disease. The major route of vaccine administration in cattle is via injection through either intramuscular or subcutaneous routes. Several products have been introduced that utilize the intranasal route of vaccine administration. There are several reasons why intranasal vaccine administration may be more beneficial: 1) Intranasal vaccine administration alleviates concerns that injections pose for Beef Quality Assurance programs. 2) Intranasal vaccine administration may be less stressful on the animal. 3) …

Intermittent Feeding Of Tylan Reduces Use Of In-Feed Antibiotics While Still Controlling Incidence Of Liver Abscesses In Finishing Steers, H. C. Muller, R. G. Amachawadi, H. M. Scott, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Liver abscesses are a cause of concern for many feedlots across the country as they lead to a decrease in feedlot performance of finishing cattle as well as a decrease in the final carcass value. Loss in carcass value is due to not only the abscessed liver being condemned, but also due to trim loss associated with the condemned liver. The macrolide drug tylosin phosphate is the drug of choice for metaphylactic treatment of liver abscesses in feedlot cattle. The Food and Drug Administration approved the drug for over-the-counter use, however, from January 2017 all medically important (used in human …

Producer Opinions On Antibiotic Use In The Beef Industry, T. Lee, C. D. Reinhardt, E. F. Schwandt, D. U. Thomson

Kansas Agricultural Experiment Station Research Reports

Antibiotic use in the beef industry is of increasing interest to consumers and has become a point of discussion for producers, veterinarians, and professional scientists in recent years. With the vast amount of information available on the internet and social media, consumers are becoming more knowledgeable about beef production practices and the use of antibiotics in the food animal industries. Furthermore, scientists have devoted a large amount of time and money to research to investigate consumer opinions and perspectives about management practices used in food animal production. However, many of these investigations fail to include the opinions and perspectives of …

Antioxidant Feeding Does Not Impact Incidence Or Severity Of Liver Abscesses, H. C. Muller, C. L. Van Bibber-Krueger, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Liver abscesses are a large source of economic loss in feedlot cattle. Not only do liver abscesses lead to a decrease in feedlot performance, but these livers are condemned in the abattoir and can also lead to a further decrease in carcass value due to trim loss. Tylosin phosphate is a metaphylactic macrolide drug that effectively decreases the occurrence of liver abscesses. The drug is approved by the Food and Drug Administration for over-the-counter use. However, in January 2017 the FDA will require a veterinary feed directive for medically important antibiotics (antibiotics that are used in human health) used in …

Differences In Efficacy Between Gamithromycin, Tilmicosin, And Tulathromycin As Metaphylactic Treatments In High Risk Calves For Bovine Respiratory Disease, T. Miller, M. E. Hubbert, E. F. Schwandt, D. U. Thomson, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

The cost of Bovine Respiratory Disease to the beef industry due to death, poorer conversions, and therapy is estimated to cost more than $3 billion per year. Identifying and mitigating Bovine Respiratory Disease in cattle can be difficult due to the increased susceptibility for Bovine Respiratory Disease in high risk cattle. One management option to minimize an outbreak of respiratory disease is the use of metaphylaxis, the mass treatment of a group of calves to reduce the incidence and adverse effects of respiratory disease on high risk animals. Criteria used to determine the necessity of metaphylactic treatment against Bovine Respiratory …

Twenty-Four Hour Holter Monitoring In Finishing Cattle Housed Outdoors, D. A. Frese, J. D. Thomason, C. D. Reinhardt, S. J. Bartle, D. N. Rethorst, G. H. Loneragan, E. F. Schwandt, D. U. Thomson

Kansas Agricultural Experiment Station Research Reports

Ambulatory electrocardiogram monitoring, in the form of Holter monitoring, has been used in human and veterinary medicine for decades as an aid in the diagnosis and determination of appropriate therapy of heart rhythm disturbances. Within veterinary medicine, Holter monitors have been primarily used in companion animal species, yet little attention has been given to food animal species. Moreover, the heart rhythm in clinically normal cattle fed high concentrate diets and housed outdoors in confined drylot facilities has not been previously reported. In order to properly identify pathologic arrhythmias in cattle, the normal rhythm and arrhythmia prevalence in healthy cattle should …

Effect Of Calsporin On Nursing Piglet Growth Performance And Fecal Microflora, M. B. Menegat, C. M. Vier, H. S. Cemin, D. Shawk, J. M. Derouchey, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 26 lactating sows (DNA 241, DNA Genetics, Columbus, NE) and litters were used in a discovery study to evaluate the effects of Calsporin, a direct-fed microbial containingBacillus subtilisC-3102, on fecal microflora of nursing pigs. The treatments consisted of providing a daily oral dose of Calsporin or a placebo control to piglets during the nursing phase. Sows were randomly assigned to treatments based on farrowing date, parity, and initial BW. The treatments were applied individually to piglets once a day from d 2 after farrowing and equalization until weaning on d 19. Sow BW, sow ADFI, …

Quantifying Medium Chain Fatty Acid Mitigation Activity Over Time Against Porcine Epidemic Diarrhea Virus In Nursery Pig Diets, J. T. Gebhardt, J. C. Woodworth, M. D. Tokach, J. M. Derouchey, R. D. Goodband, C. K. Jones, S. S. Dritz

Kansas Agricultural Experiment Station Research Reports

Medium chain fatty acids (MCFA) are six to twelve carbon length molecules that have shown significant promise as potential mitigants of biological hazards in feed and feed ingredients. The use of residual duration of activity approaches, such as MCFA, have significant advantages compared to point-in-time mitigation strategies. The primary advantage of MCFA is the ability to mitigate the risks generated by post-processing contamination; however, the duration of mitigation activity has not been established. Therefore, the objective of this experiment was to characterize the mitigation properties of MCFA-treated swine feed 40 d following feed manufacturing. Treatments (n = 8) consisted of …

Identifying Immuno-Dominant And Neutralizing Epitopes From K88 Fimbriae Of Enterotoxigenic Escherichia Coli (Etec), T. Lu, W. Zhang

Kansas Agricultural Experiment Station Research Reports

Enterotoxigenic Escherichia coli (ETEC) bacteria are the primary cause of diarrheal disease, especially porcine post-weaning diarrhea (PWD). Post-weaning diarrhea is one of the most common diseases in piglets 3 to 10 days after weaning and causes the loss of millions of dollars annually to United States swine industry and other countries. These ETEC bacteria produce two types of virulence factors: 1) fimbriae adhesins, which promote bacterial attachment and colonization in pig small intestine; and 2) enterotoxins that disrupt fluid homeostasis and cause fluid hype-secretion and watery diarrhea. The F4 (K88) is the most important fimbria in ETEC bacteria causing PWD. …

Genome Diversity And Molecular Detection Of Prrs Field Strains And Vaccine Strains, And Pcv3 And Pcv2 Strains, Y. Wang, F. Yuan, X. Liu, W. Zheng, H. Zhang, J. Zhang, K. Yoon, L. Peddireddi, Y. Fang, G. Anderson, J. Bai

Kansas Agricultural Experiment Station Research Reports

Molecular diagnosis of porcine reproductive and respiratory syndrome virus (PRRS) and porcine circo virus (PCV) are challenging due to high genetic diversity in the viral genomes. Differentiating PRRS vaccine strains is even more challenging and is currently done by DNA sequencing, which is expensive and time-consuming. A multiplexed system (Luminex) allowing multiple detection targets in the same reaction is available. However, this system is not fully developed for common swine pathogens. Therefore, an assay was built to detect the majority of field PRRS strains by using different pairs of primers, and at the same time, to provide differentiation of the …
