Two experiments involving Brangus and Hereford x cows (3 to 10 yr) were conducted at four locations in western Texas determine the effects of supplemental feeding interval on serum urea nitrogen (SUN) patterns, intake supplement forage, winter changes live body weight condition score. Treatments control (Control; no feed) equivalent .91 kg/d cottonseed meal (CSM) fed daily (Daily), three times per week (3T/WK), or one time (WK). At each location, pasture group was given all treatments (four...
This survey consisted of data collected from 23 beef harvest plants to document transportation procedures, management practices, and health assessments market dairy cows bulls (about n ≅ 7,000 animals). Gooseneck/bumper-pulled trailers were used more often transport cattle than whereas tractor-trailers cattle. All loads (n = 103) met the American Meat Institute Foundation guidelines for spacing. Loads where 3% slipped during unloading observed in 27.3% 29.0% loads. Beef had numerically...
There exist common-pool resource systems where it is difficult to prevent prospective beneficiaries from receiving profits the use or harvest of shared resources, and they are often subject continual utilization, leading degradation economic erosion (a behavior known as ‘tragedy commons’). Nigerian nomadic grazing currently undergoing tragedy commons pose a great challenge agrarian communities, herders political stability throughout country due violent conflicts property destruction migrate...
Tanglehead is a native bunchgrass with pan-tropical distribution. Historically, tanglehead was common but not abundant in southern Texas and considered decreaser whose presence indicated good range condition. Beginning the late 1990s, Coastal Sand Plain ecoregion witnessed dramatic increases abundance distribution of tanglehead: thousands acres former grasslands were replaced by dense monotypic stands tanglehead, reducing habitat quality for livestock wildlife. Our research has focused on...
The use of limpograss [ Hemarthria altissima (Poir) Stapf et C.E. Hubb.] as a pasture plant is relatively recent development. Available cultivars possess distinctly different characteristics. ‘Bigalta’ has been widely planted on peninsular Florida Spodosols, but stand loss under grazing common. A more persistent cultivar, ‘Floralta’, recently become the most grown cultivar in Florida. When same pasture, Bigalta was heavily grazed by yearling steers ( Bos indicus L. and taurus spp.) before...
In a 4-yr study, molasses (M; 6% CP), molasses-urea (MU; 17.5% CP; 92% molasses, 4% urea and water) molasses-cottonseed meal-urea (MCSM; 73% 25% cottonseed meal, 1% were compared as winter supplements for Braford cows (514 matings) consuming low-quality forage. Cows fed 1.35, 1.50 1.27 kg·head−1·d−1 of the respective 127 d beginning in December. wintered on bahiagrass pasture (avg 8%CP) stargrass hay 5% CP).

The three most well-recognized sustainability pillars are environmental, social, and economic. Ranch economic hinges on asset value dynamics ranch profitability. metrics include multiyear average positive accrual adjusted net income, rate of return assets (valued at market value) >1.5%, equity to ratio >50%, current >2%.
