A Phenotypic Characterization of Rarámuri Criollo Cattle Introduced Into the Southwestern United States1
Archivos Latinoamericanos de Producción Animal. 2020. 28 (34) A Phenotypic Characterization of Rarámuri Criollo Cattle Introduced into the Southwestern United States1 Matthew M. McIntosh Alfredo L. Gonzalez2 †, Andres F. Cibils3 Richard E. Estell2, 3 Shelemia Nyamuryekung’e2 Felipe A. Rodríguez Almeida4 Sheri A. Spiegal2 Department of Animal and Range Sciences, New Mexico State University, USA Abstract. Our objective was to describe key phenotypic characteristics of a population of Rarámuri Criollo (RC) cattle introduced from the Copper Canyon of Chihuahua, México into the Southwestern United States almost two decades ago. We recorded 26 phenotypic traits of 37 RC individuals including mature cows, firstcalf heifers, and mature bulls raised at the USDAARS Jornada Experimental Range in southern New Mexico. This herd of RC cattle exhibited intermediate body sizes (390 kg) compared to the smaller Corriente (300 kg) and larger Texas Longhorn (400 kg) and Florida Cracker cattle (400 kg). Coat colors were similar to those described for other Criollo biotypes but horn shape and size of RC appear to be different than that of other USbased Criollo breeds. Though smaller than commercial beef breeds, RC cattle appear to be wellmatched to the Southwestern US environments as evidenced by previous studies that evaluated their grazing behavior, weight gains, and carcass quality. Rarámuri Criollo cattle are a genetic resource whose conservation could be critically important for climate change adaptation of ranches in the desert Southwest.

Proceedings BRAND CREATION for a PRESCRIBED FIRE CULTURE UTILIZING KEY SOCIAL MEDIA PARAMETERS
Proceedings BRAND CREATION FOR A PRESCRIBED FIRE CULTURE – UTILIZING KEY SOCIAL MEDIA PARAMETERS. Lars Coleman*1, J. Kelly Hoffman1, Thomas McDaniel1, R. Patrick Bixler2, Urs P. Kreuter1, Morgan Russell3; 1Texas A&M University, College Station, TX, 2University of Texas, Austin, TX, 3Texas A&M Agrilife Extension, San Angelo, TX ABSTRACT There is much information about the safe application and ecological benefits of prescribed fire as a rangeland management tool. Accordingly, many federal and state agencies, private entities, and landowner representative associations promote the use of prescribed fire and provide information, training and/or equipment to enhance its safe use. However, there is still widespread public resistance to the broad scale use of this management tool. Social media provide a valuable outlet for positive information about prescribed fire to a broader audience. However, social media are underutilized to bridge the gap between current decision makers and potential prescribed fire users. Given the rising age demographic of farmers and ranchers across the rangeland of the USA, a new generation of decision makers on these lands is inevitable. The shift to a younger demographic will result in greater use by land managers of social media sites. Building a foundation for information sharing for this group is critical for three reasons. First, there is a need to ensure greater access to information by a newer generation. Second, effective mentorship requires information utilization across multiple media platforms as a supplement to in person discussions. Third, information needs to be shared further through easier means. Interviews were conducted for landowner representative associations and government agency employees about their opinions of prescribed fire and the use of information about this tool. -

Abstract Proceedings of the 72nd Society for Range Management International Meeting February 10-13 Minneapolis, Minnesota 1 A Comparison of Two Methods to Estimate Heifer Activity Using GPS and Accelerometer Data Fatima Continanza, New Mexico State University, Las Cruces, New Mexico Jennifer Muscha, USDA-ARS Fort Keogh, Miles City, Montana Mark Petersen, USDA-ARS, Miles City, Montana Andrew Roberts, USDA-ARS, Miles City, Montana Qixu Gong, New Mexico State University, Las Cruces, New Mexico Huiping Cao, New Mexico State University, Las Cruces, New Mexico Andrés Cibils, New Mexico State University, Las Cruces, New Mexico There is increasing interest in the use of low cost GPS units to monitor livestock movement and activity patterns on rangeland. Such devices seldom include movement sensors. On the other hand, 2- or 3-axes accelerometers included in several commercially available GPS units often yield activity data with low animal-to-animal consistency. Our objective was to compare two methods of estimating activity of rangeland heifers monitored with collars equipped with GPS and 2-axis accelerometers. The first method (VEL) involved classifying GPS points based on movement velocity thresholds. Resting was assumed when velocity < 2 m/min, velocities between 2-25 m/min were assumed to indicate grazing, and velocities > 25 m/min were classified as traveling. The second method (MOV) included a classification tree model that discriminated between resting, grazing, and traveling activities considering the distance between GPS points and both horizontal and vertical movement values recorded by a 2-axis accelerometer. Lotek 3300LR GPS collars were fitted randomly on heifers (18 days) in spring 2015 (n=20), 2016 (n=18), and 2017 (n=41). -
