Effect Of Dietary Supplementation Of Symbiotic, Prebiotics And Probiotics On Conformation Of Teats In Rabbits, Saqib Kakar, Allah Bux Kachiwal, Saeed Ahmed Soomro, Akeel Ahmed Memon
Journal of Bioresource Management
This study evaluated the effects of dietary supplementation with prebiotics, probiotics, and symbiotics on the reproductive and physiological performance of New Zealand White rabbits, emphasizing teat conformation. Forty-eight rabbits were divided into four groups: control (a), prebiotics (b), probiotics (c), and symbiotics (d). During the first parity, teat conformation varied across dietary treatments, with group d (symbiotic supplementation) generally exhibiting superior teat morphology. Horizontal teat length was highest in group a (4.38±0.35) and lowest in group d (4.02±0.43). The rear teat distance from the floor was longest in group d (1.71±0.25) and shortest in group a (1.41±0.50), with a similar …
Hematologic And Serum Biochemical Reference Intervals For Formosan Sika Deer (Cervus Nippon Taiouanus) From A Semi-Free-Ranging Population In Taiwan, Chen-Wei Wang, Ke-Lun Chen, Hung-Yi Wu, Chia-Ying Lin
Hematologic And Serum Biochemical Reference Intervals For Formosan Sika Deer (Cervus Nippon Taiouanus) From A Semi-Free-Ranging Population In Taiwan, Chen-Wei Wang, Ke-Lun Chen, Hung-Yi Wu, Chia-Ying Lin
The Thai Journal of Veterinary Medicine
The Formosan sika deer (Cervus nippon taiouanus), an endemic Taiwanese subspecies, holds a pivotal role in local conservation. This study addresses a significant knowledge gap by establishing population-specific reference intervals (RIs) for this species, as existing RIs are based on limited captive populations and may not accurately reflect the health of semi-free-ranging cohorts. We analyzed 632 sampling events from 232 healthy adult deer within Kenting National Park over 12 years (2013–2024). This study adhered to ASVCP guidelines, establishing instrument-specific RIs and employing linear mixed-effects models (LMMs) to evaluate the complex interactions among analytical instruments, sex, and body weight. …
Preliminary Study Of A Support System For Noninvasive Pneumonia Detection Using Breath Sound Analysis In Calves, Yasuhiro Morita, Seiji Inoue, Satoshi Ohkura
Preliminary Study Of A Support System For Noninvasive Pneumonia Detection Using Breath Sound Analysis In Calves, Yasuhiro Morita, Seiji Inoue, Satoshi Ohkura
The Thai Journal of Veterinary Medicine
Pneumonia in calves is caused by a complex association between host, pathogen, and environmental factors, and it is challenging to detect the subclinical stages. Therefore, it is crucial to accurately and rapidly identify calves with pneumonia on farms to provide appropriate treatment in a timely manner. In the present study, we focused on the frequency components of lung sounds to distinguish calves with and without pneumonia, without the need for veterinary expertise. In addition, we evaluated the pathogenesis of pneumonia by clarifying the relationship between the frequency components of lung sounds and lung ultrasound findings in calves. Although further case …
The Effect Of Diet Formulations Containing Different Protein Sources On Energy And Nitrogen Utilization In Lactating Jersey Cows, Kortney Ann Harpestad
The Effect Of Diet Formulations Containing Different Protein Sources On Energy And Nitrogen Utilization In Lactating Jersey Cows, Kortney Ann Harpestad
Department of Animal Science: Dissertations, Theses, and Student Research
It is well understood that lactating dairy cows require metabolizable protein (MP) for milk yield and milk protein synthesis. Diets with conventional feed sources like corn and soybean meal (SBM) may not sufficiently meet all MP and amino acid (AA) requirements so supplementation with more rumen undegradable protein (RUP) rich feeds or rumen-protected AA can be fed to support animal performance. The growth trajectory of biofuels has resulted in dramatic increases in the production of feeds like heat treated soybean meal (HTSBM). While the chemical composition of this product is understood, there is a need to better understand how HTSBM …
Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn
Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn
LSU Master's Theses
While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …
Diagnosis, Treatment, Genetic Basis, And Prevention Of Canine Hip Dysplasia, Nathaniel R. Woody
Diagnosis, Treatment, Genetic Basis, And Prevention Of Canine Hip Dysplasia, Nathaniel R. Woody
Senior Honors Theses
Canine Hip Dysplasia (CHD) is a genetic disorder that results in an improper formation of the hip joint. This results in joint laxity, which eats away at the cartilage of the acetabulum. CHD causes arthritis, making normal walking painful for dogs. CHD is the result of many different genes and mutations working together. The best way to prevent CHD in dogs is to selectively breed animals who are not genotypic for the mutation. For dogs that already carry the mutation responsible for CHD the earlier the diagnosis and treatment the better chance they have of a full pain free life …
Digestibility, Palatability, And Nutrient Composition Of Three Species Of Whole Prey In Three Species Of Snakes, Morgan R. Kienzle
Digestibility, Palatability, And Nutrient Composition Of Three Species Of Whole Prey In Three Species Of Snakes, Morgan R. Kienzle
Department of Animal Science: Dissertations, Theses, and Student Research
Snakes in human care often lack diversity in the diet. Rodents account for the majority of meals, while wild snakes are consuming a varied diet composed of multiple different whole prey species. By feeding only one species of prey, the chance of nutrient deficiencies and other health concerns increases. To promote variety in the managed diet, two commercially available whole prey species (mice (Mus musculus) and chicks (Gallus spp.)) and one novel species (Seba’s short-tailed bats (Carollia perspicillata)), were analyzed for their dry matter (DM), organic matter (OM), crude protein (CP), crude fat …
Methane Mitigation And Its Effects On Energy Utilization In Lactating Dairy Cattle, Shan C. Sherwood
Methane Mitigation And Its Effects On Energy Utilization In Lactating Dairy Cattle, Shan C. Sherwood
Department of Animal Science: Dissertations, Theses, and Student Research
Improved methane (CH4) mitigation strategies are needed to achieve the greenhouse gas emission goals of the dairy industry. The first experiment was conducted to evaluate the effects of feeding black cumin (Nigella sativa) seed oil and acetate (BCA) on CH4 production and whole-animal energy utilization. Twelve dry Jersey cows were used in a 2-period crossover design study with 28d periods. The BCA treatment was compared to a control diet with corn oil. Both BCA and corn oil were added to the base diet as a top dress. Results from this study did not show any …
Gonadotropin-Releasing Hormone Ii And Its Receptor: Novel Regulators Of Semen Quality And Follicular Function In Swine, Caitlin Elizabeth Ross
Gonadotropin-Releasing Hormone Ii And Its Receptor: Novel Regulators Of Semen Quality And Follicular Function In Swine, Caitlin Elizabeth Ross
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Pigs are the only mammalian livestock species encoding functional proteins for the second form of gonadotropin-releasing hormone (GnRH-II) and its receptor (GnRHR-II). In the first study, GnRHR-II localized to developing germ cells and the connecting piece of ejaculated spermatozoa. Concurrently, GnRH-II was most abundantly produced in the testis compared with other reproductive tract organs and was present within seminal plasma. Moreover, treatment of extended semen with GnRHR-II analogues altered sperm motility, morphology, and kinematics. For remaining studies, we utilized a swine line with ubiquitous knockdown of GnRHR-II (GnRHR-II KD) developed in our laboratory. The second study demonstrated that circulating GnRH-II …

The Thai Journal of Veterinary Medicine
Colostrum composition, including lactose concentration in relation to metabolomic profiles on kids’ growth performance of Black Bengal goats, has not yet been elucidated. Macronutrients, including lactose and metabolomic profiles, were determined in 37 colostrum samples using MilkoScan and 1H-nuclear magnetic resonance technique, respectively. Kids’ growth performance, including birth weight, average daily gain at 0–4 weeks (ADG0-4W), 4–8 weeks (ADG4-8W), and wean weight were determined. A total of 51 metabolites were detected in the colostrum. From the general linear model for univariate analysis, kids born from multiple litter sizes showed lower ADG during the first month postpartum (P = 0.004). …
Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston
Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston
Nebraska Beef Cattle Reports
This study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Heifers were artificially inseminated with semen from one of three single-sires or semen from a combination of the same three sires. Pregnancy rates did not significantly differ. Paternity testing suggests sire parentage can be unequal when semen is mixed from multiple sires. In summary, producers can expect similar pregnancy rates using single-sire and multi-sire semen, but progeny may have unequal sire representation.

Mobulas (manta and devil rays) are large-scale ram filter feeders that separate planktonic food particles from large volumes of water with minimal clogging. This contrasts with most human-made filters that can suffer from problematic clogging requiring additional mechanisms for clearing blocked surfaces and maintaining performance. Prior studies have shown that mobulas employ a unique mechanism referred to as ricochet separation to filter feed, whereby captive vortices in filter pores cause particles to bounce off the filter surfaces and away from the filter pores. This mechanism enables the filtration of particles smaller than the pore size and reduced clogging. However, few …
Assessing Reproductive Health In Zoo-Managed African Elephant Bulls (Loxodonta Africana), Kaitlyn Marie Campbell
Assessing Reproductive Health In Zoo-Managed African Elephant Bulls (Loxodonta Africana), Kaitlyn Marie Campbell
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Populations of zoo-managed African elephant (Loxodonta Africana) exhibit substantial individual- and population-level variation in reproductive success, yet research has largely focused on females, leaving male fertility poorly understood. Subfertility in bulls, characterized by low libido and inconsistent semen quality, poses significant challenges to genetic management and long-term population sustainability. This study a) systematically evaluates semen quality, b) identifies physiological, behavioral, social, and environmental determinants of fertility, and c) advances ex situ conservation through the expansion of the African elephant sperm bank. Between January 2023 and July 2025, 209 semen collection events were conducted from 13 sexually mature bulls …

The feeding ecology of wildlife populations has important implications for individual health, population productivity and distribution patterns. For ursids (bears), food resources and feeding behaviour primarily affect population dynamics via effects on cub production and survival. Much of what is known about the feeding ecology of bears is based on analyses of tissues collected from capture-based research efforts, harvested animals or non-invasive approaches. However, inference about diet from hair has been limited by a lack of quantitative data on the timing of the moult and hair growth rates. We conducted a study to develop and test two methods of quantifying …
