Evaluation Of Internal Markers For Predicting Digestibility And Fecal Output By Cattle Fed Bermudagrass Hays Of Varying Quality, Juvenal Kanani Aug 2012

Evaluation Of Internal Markers For Predicting Digestibility And Fecal Output By Cattle Fed Bermudagrass Hays Of Varying Quality, Juvenal Kanani

Graduate Theses and Dissertations

The potential of in situ rumen undegradable dry matter (RUDM), indigestible neutral-detergent fiber (INDF), indigestible acid-detergent fiber (IADF), acid-detergent insoluble ash (ADIA), alkaline-peroxide lignin (APL), and acid-detergent lignin (ADL) to predict digestibility (DMD) and fecal output (FO) by cattle fed bermudagrass [Cynodon dactylon (L.) Pers.] hay-diets categorized by their low (L), medium low (ML), medium high (MH), or high (H) CP concentrations (79, 111, 131, and 164 g/kg DM, respectively) was evaluated. The second objective was to evaluate the effects of time (0600, 1200, 1800, and 2400 h) of fecal sampling on the prediction of FO and DMD. A replicated …


Effects Of Management Strategies And Molecular Breeding Values On Cattle Performance And Carcass Traits, Benjamin Collins Williamson May 2012

Effects Of Management Strategies And Molecular Breeding Values On Cattle Performance And Carcass Traits, Benjamin Collins Williamson

Graduate Theses and Dissertations

Forty-eight Gelbvieh x Angus steers (265 ¡À 40 kg) were utilized to determine the relationships among molecular breeding values (MBV), steer performance, and carcass traits. Body weight (BW), hip height (HH), hip width (HW), exit velocity (EV; rate at which steers exited the squeeze chute and traversed 1.8 m) and body ultrasound measurements of steers were recorded at d 0, 93 and 154 of grazing mixed stockpiled endophyte-infected and -free tall fescue. Tissue samples were collected for genomic profiling (Igenity, Merial Limited, Duluth, GA). Steers were transported to the Oklahoma State U fed for 159 d, harvested and carcass parameters …


Characterization Of The Vasotocin Receptor Subtype 4 (Vt4r) In The Brain And Pituitary Gland Of The Chicken, Gallus Gallus, Rajamani Selvam May 2012

Characterization Of The Vasotocin Receptor Subtype 4 (Vt4r) In The Brain And Pituitary Gland Of The Chicken, Gallus Gallus, Rajamani Selvam

Graduate Theses and Dissertations

The present study investigated the distribution of the vasotocin subtype four receptor (VT4R) in brain and pituitary gland of the chicken, Gallus gallus. The anterior pituitary cell types associated with the VT4R were also determined. Two polyclonal antibodies were raised in rabbit against a cocktail of peptides, 15 amino acids from the amino terminal region and 17 amino acids from the carboxy terminal region of VT4R receptor. The antibody was validated utilizing the Western blot and immunocytochemistry. A single band at 47KDa utilizing membrane protein extracts of chicken brain and pituitary tissues was shown for the VT4R antibody. A peptide …
