- Abstract:
- ... A key challenge of precision grazing systems is identifying behavior anomalies associated with situations of reduced animal production and wellbeing. We determined typical ranges of diel variation of movement and activity patterns of steers on rangeland to identify metrics that could serve as sensitive indicators of behavior anomalies. Seventeen Raramuri Criollo or Criollo crossbred yearling steer ...

- Abstract:
- ... Honey mesquite (Prosopis glandulosa Torr.) is a potential foraging resource in southwestern United States (US) rangelands and in other semi-arid rangelands. Yet, intake by ruminants is limited. We conducted a series of in vitro digestion experiments to assess phenological changes in nutrient value and relative digestibility of honey mesquite leaves, pods and 'owers throughout the 2012 growing seas ...

The objective of this study was to compare foraging behavior of mature Raramuri Criollo (RC, heritage breed) and Angus Hereford crossbred (AH, commercial breed) cows grazing Chihuahuan Desert rangeland during summer and winter in three consecutive years. Movement, activity, and spatial distribution variables were calculated from 10-min interval GPS positions of 5–11 randomly selected cows of each ...

- Abstract:

We analyzed a 52-yr time series (1967−2018) of precipitation, ambient temperature, and perennial grass production (PGP), as well as 14 yr (2001−2014) of Moderate Resolution Imaging Spectrometer (MODIS)-derived vegetation phenomet ...

- Abstract:

Rarámuri Criollo cattle producers often crossbreed their cows with improved beef-breed bulls and/or retain and develop their yearlings on rangeland because of limited weaned calf markets, however it is unknown if Rarámuri Criollo steers exhibit marketable weight gains and carcass qualities, or desirable grazing behaviors documented in cows of this biotype. We evaluated two cohorts (cohort: 1 = 31, ...

We studied foraging patterns of Raramuri Criollo (heritage breed, “RC”) and Angus x Hereford (commercial beef breed, “AH”) cows in relation to ambient heat and body temperature during summer (2016 and 2017) and winter (2017 and 2018) in the Chihuahuan Desert. Cows of each breed grazed separately in two adjacent pastures (~1100 ha) in a crossover design for four weeks in each season/year. Animals w ...

Thirty-five cows were released into a 405-m2 rectangular dry lot, either in pairs (pilot tests) or individually (experiment tests), that contained 12 food bowls arranged in an open semicircle and placed approximat ...

- Abstract:
- ... Targeted livestock grazing is a proven tool for manipulating rangeland vegetation, and current knowledge about targeted livestock grazing is extensive and expanding rapidly. Targeted grazing prescriptions optimize the timing, frequency, intensity, and selectivity of grazing (or browsing) in combinations that purposely exert grazing/browsing pressure on specific plant species or portions of the lan ...

- Abstract:
- ... Adopting livestock with heritage genetics may help to improve the sustainability of agriculture on rangelands with harsh, challenging conditions. In the Chihuahuan Desert, preliminary evidence suggests that heritage Raramuri Criollo exploit a greater variety of range resources than do conventional cattle. Accordingly, the use of Raramuri Criollo may help sustain vegetation and soils, as well as ag ...

- Abstract:
- ... Projected global increases in ruminant numbers and loss of native grasslands will present a number of challenges for livestock agriculture. Escalated demand for livestock products may stimulate interest in using shrubs on western rangelands. A paradigm shift is needed to change the role of shrubs in rangeland ecosystems. Progress has occurred in identifying mechanisms to increase shrub use, but mo ...
