Texas A&M Beef Cattle Short Course: Program Evaluation, Nicola Oosthuizen, Pedro Fontes, Graham C. Lamb, Jason J. Cleere

The Journal of Extension

Survey results (n = 3,748) collected over a period of 7 years from the Texas A&M Beef Cattle Short Course (BCSC) were analyzed to evaluate course demographics and the impact of the course on attendees. Results of this survey demonstrate that attendee demographics of the BCSC are representative of beef cattle producers in the United States and that the BCSC is effective at delivering information that positively impacts beef production in Texas. Extension professionals can make use of these findings to tailor future education programs to better serve the needs of beef cattle producers nation-wide.

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus is an important component of bodily functions and is critical for adequate growth and development. This experiment evaluated the effect of maternal phosphorus intake on the growth and health of the calves. Treatments were 1) a free-choice mineral containing no supplemental P or 2) a free-choice mineral with 4% supplemental phosphorus. Primiparous, or pregnant for the first time, crossbred Angus beef cows (n = 36) were stratified by body weight and pregnancy status (bred by artificial insemination or natural service) then assigned to pasture groups (4 groups, 2/treatment, 9 heifers/group). These bred heifers had been receiving these same dietary …

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, …

Seasonal Variation In Vitamin D Status Of Beef Cattle Reared In The Central United States, E Casas, J D. Lippolis, L A. Kuehn, T A. Reinhardt

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The objective was to retrospectively measure seasonal sunlight-associated variation in serum concentrations of 25-hydroxyvitamin D (25OHD) in beef cattle. The concentration of 25OHD was measured in crossbred animals born from March to May in 2011 and 2012. Vitamin D status 2 to 3 mo after birth (period 1) was only available for 2012 calves and was measured in June 2012. Period 1 animals had serum 25OHD concentrations of 26.3 +- 1.5 ng/mL. The 25OHD concentrations for late summer (period 2) were 46.6 +- 1.4 and 51.0 +- 1.5 ng/mL for 2011 and 2012, respectively. Serum concentration of 25OHD in early …

Beef Marketing As A Guide To Production Techniques, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …
