Book Description
Cattle consuming low-protein forage (7% CP) require additional supplemental protein to maintain BW and BCS. Daily delivery of protein supplements places undue financial burden on cattle producers. Supplementing cows as infrequently as once every 6 d) has resulted in similar changes cow BW and BCS when compared to daily supplementation. As calving season nears, producers may wish to increase supplementation frequency. The responses to a change in supplementation frequency during the third trimester of gestation have not been widely investigated. Therefore, our objective in Study 1 was to evaluate the effect of altering supplementation frequency during late gestation on performance of spring-calving cows grazing low-quality, dormant native range and supplemented with dried distillers grains with solubles (DDG). Angus x cows (n = 238; mean age = 6 ± 2.5 yr; average initial BW = 618 ± 56.2 kg; average initial BCS = 5.7 ± 0.03) were stratified by age, BW, BCS, and assigned randomly to 1 of 4 treatments: 1) DDG daily (D1); 2) DDG once every 6 d (D6); 3) DDG daily from d 1 to d 60 and then every 6 d (D1-D6); 4) DDG every 6 d from d 1 to d 60 and then daily (D6-D1). Treatments were initiated 100 d prior to expected onset of calving. Cow BW and BCS were measured every 28 d. Cows were sorted daily before supplementation at 0830 h. Supplement delivery was calculated to meet dietary CP requirements. Increasing supplementation frequency 28 d prepartum negatively affected final BW and BW change from d 61-88 for the D6-D1 supplementation group (P 0.05) compared to other supplementation groups. Cow BW change for the study (d 1-88) was also less (P

Book Description
Range and Animal Sciences and Resources Management is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Rangelands comprise over forty percent of the earth's land surface and, as one of the most prevalent land systems on the planet, rangelands are critical habitats for myriad plant and animal species and form many of the world's major watersheds Rangelands are categorized in two distinct ways: (a) as a type of land or (b) a type of (land) use. This theme with contributions from distinguished experts in the field discusses about Range and Animal Sciences and Resources Management in several related topics. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Book Description
One of the main animal welfare concerns in beef cattle production is that of pain and distress. Dehorning, castration, and branding are husbandry procedures which can cause pain and discomfort. Less acute but still distressful are those issues related to the animal environment. Extreme natural conditions can result in cattle that are heat and/or cold stressed. Drought and the resulting overstocking for available feed resources can also reduce body fatness. These are important welfare issues in modern beef production. The following bibliography explores these issues and more and should provide a useful resource for scientists, veterinarians, extension specialists, students, and others.
