Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray

Electronic Theses and Dissertations

After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect …

Analyzing The Management Practices Of East Texas Beef Cattle Producers, Hiliary Cheyenne Swor

Electronic Theses and Dissertations

A survey of East Texas beef cattle producers was designed to evaluate the management practices that were prevalent in the area. Demographic and cattle operation data from 103 respondents were analyzed using SPSS (Version 25; Chicago, IL). This electronic-based survey was distributed through Qualtrics. Respondents were located in Angelina, Nacogdoches, or Cherokee county. Most producers (38.8%) had a Bachelor’s degree. A negative correlation was established between castration method and weaning weight (p = - 0.204). Calves were weaned 50 pounds heavier when band or surgically castrated. Females were less likely to castrate their calves or utilize a mineral program. Approximately, …

Evaluation Of Absorbezz On Swine Reproductive Health And A Comparative Study Of Two Commercially Available Swine Show Feeds, Scott G. Sutton

Electronic Theses and Dissertations

The efficacy of a feed supplement fed to gilts and sows was tested in study I. The supplement was stated to improve reproductive soundness, conception rates, immune health, and overall well-being of livestock. Thirty gilts were split into a control group (Base diet) and a treatment group (Absorbezz® 0.32 mL on base diet). Upon completion of the trial results indicate the treatment group significantly underperformed (

Two commercially available show pig growing rations were tested in study II to find a high quality, cost efficient product. A total of 10 pigs (5 barrows, 5 gilts), at an average weight of …

Evaluation Of Different Probiotic Strains Supplemented In Commercial Broiler Rations And Their Influences On Performance, Yield, And Intestinal Microbiota., Justin M. Glasscock

Electronic Theses and Dissertations

The objective of this study was to evaluate Bacillus megaterium, Bacillus licheniformis, and Bacillus subtilis, as probiotic strains compared to Bacitracin Methylene Disalicylate (BMD) 50 as the antibiotic growth promotor, supplemented in commercial broiler rations and their influences on performance, yield, and intestinal microbiota. This trial was completed as a randomized-block design with 4,800 birds split into 96, 5’x10’ pens, and randomly assigned to one of eight treatment groups. The birds were placed at a stocking density of 1.00 ft²/bird, (50 birds/pen), and reared on used pine shaving for 55 days. Throughout the study, bird …
