Physiology Collection

The peripartal dairy cow experiences a state of reduced liver function coupled with increased inflammation and oxidative stress. This study evaluated the effect of supplementing basal diets with rumen-protected Met in the form of MetaSmart (MS) or Smartamine M (SM) (both from Adisseo Inc., Antony, France) during the peripartal period on blood and hepatic biomarkers of liver function, inflammation, and oxidative stress. Thirty-seven multiparous Holstein cows were fed the same basal diet from −50 to −21 d relative to expected calving [1.24 Mcal/kg of dry matter (DM); no Met supplementation]. From −21 d to calving, the cows received diets …

Generation And Use Of Monoclonal Antibodies To Ldentify Subpopulations Of Post Thaw Stallion Sperm, Sarah Abdulaziz Almuhanna

Masters Theses

Artificial insemination (AI) is commonly used for breeding of horses. Selecting high quality semen is critical to AI success but is difficult to achieve. In this study, we investigate the potential of generating antibodies against stallion sperm to identify subpopulations of post-thaw sperm based on surface markers. Female Balb/C mice are immunized with semen from a 24-year-old fertile stallion followed by booster immunizations each week for at least six weeks. Monoclonal antibodies are generated by fusion of myeloma cells to mouse spleen cells. Eight monoclonal antibodies resulting from these fusions are subdivided into four immunostaining patterns. These patterns differentially recognize …

Timing For Male Reproductive Tract Gene Expression And Gonopore Complex Development Of Giant Freshwater Prawn (Macrobrachium Rosenbergii), Prapruddee Piyaviriyakul, Damri Darawiroj

The Thai Journal of Veterinary Medicine

Mono-sex culture of giant freshwater prawns (Macrobrachium rosenbergii) gives more benefits than mixed-sex culture because of high market demand for male prawns. Unfortunately, sex differentiation in crustaceans could not obviously be observed in their early larval stage. Therefore, sex segregation or sex reversal techniques need to be developed and timing for sex differentiation in M. rosenbergii during larval development needs to be examined. In this study, three genes related to male reproductive hormone (IAG, MRR and MAL) were isolated and amplified from terminal ampulae (TA) of adult male M. rosenbergii. The male specific transcripts demonstrated that they could be used …

Glutaredoxin 2 (Grx2) Gene Deletion Induces Early Onset Of Age-Dependent Cataracts In Mice, Hongli Wu, Yibo Yu, Larry David, Ye-Shih Ho, Marjorie . F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

Glutaredoxin 2 (Grx2) is an isozyme of glutaredoxin1 (thioltransferase) present in the mitochondria and nucleus with disulfide reductase and peroxidase activities, and it controls thiol/ disulfide balance in cells. In this study, we investigated whether Grx2 gene deletion could induce faster age-related cataract formation and elucidated the biochemical changes effected by Grx2 gene deletion that may contribute to lens opacity. Slit lamp was used to examine the lenses in Grx2 knock-out (KO) mice and age-matched wild-type (WT) mice ages 1 to 16 months. In the Grx2 null mice, the lens nuclear opacity began at 5 months, 3 months sooner than …

Genetic Parameter Estimates And Breed Effects For Calving Difficulty And Birth Weight In A Multi-Breed Population, Cashley Ahlberg

Department of Animal Science: Dissertations, Theses, and Student Research

There are multiple breeds of beef cattle available to utilize in breeding systems to maximize production and economics. Calving difficulty (dystocia) is a significant cost to beef production and is more prevalent in first-calf heifers. The objectives of this study were to estimate genetic parameters and breed differences for calving difficulty and birth weight as a first step towards the development of across-breed adjustment factors for calving difficulty.

Two models were employed to analyze birth weight (BWT) and calving difficulty (CD) recorded on 4,579 first parity females from the Germplasm Evaluation program at the United States Meat Animal Research Center …
