Annual Forages Differ in Response to Partial-Season Irrigation Deficit in Both Spring Seeded and Summer Seeded Cropping Systems

Creator:: Fan, Qianqian
Abstract:: Water scarcity during summer becomes a serious problem in the Pacific Northwest, threatening forage production provided to livestock. Annual forages show great potential in handling drought because of their flexibility in seeding date and short growing season, and can shift the production to periods of feed shortage and fill the...

Impacts of Stocking Density on Development and Puberty Attainment of Replacement Beef Heifers

Creator:: Schubach, Kelsey M.
Abstract:: The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...

Creep-feeding to stimulate metabolic imprinting in nursing beef heifers : impacts on heifer growth, reproductive, and physiological parameters

Creator:: De Meireles Reis, Maria
Abstract:: The following experiment presented herein compared growth, physiological, and reproductive responses of beef heifers with (MI) or without (CON) access to a creep-feeder, as a manner to stimulate metabolic imprinting while nursing their dams. On d 0 of the experiment, 60 Angus × Hereford heifers were ranked by initial BW...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

Management Strategies to Improve Immune Function and Performance of Feeder Cattle

Creator:: Lippolis, Katana D.
Abstract:: Three experiments evaluated the effects of different management strategies on immune function and performance of feeder cattle. The objective of experiment 1 was to compare the effects of anticipating, delaying, or vaccinating against Bovine Respiratory Disease (BRD) at the time of weaning and feedlot entry on growth, DMI, and plasma...

Nutritional strategies to improve the reproductive performance of beef females

Creator:: Cappellozza, Bruno Ieda
Abstract:: In the first set of studies, 2 experiments evaluated the influence of supplement composition on ruminal forage disappearance, performance, and physiological responses of Angus × Hereford cattle consuming a low-quality, cool-season forage (8.7 % CP and 57 % TDN). In Exp. 1, 6 rumen-fistulated steers housed in individual pens were...

Cooling characterization and practical utilization of sub-micron slurry ice for the chilling of fresh seafood

Creator:: Keys, Dustin R.
Abstract:: Consumption of seafood products continues to grow each year, but post-harvest losses and inedible seafood waste remain as high as 25%. Ice-based systems are the most common form of preservation to increase shelf life, preserve product quality, and enhance product safety. Slurry ice is a type of chilling media, consisting...

Effects of camelina meal supplementation on ruminal forage degradability, performance, and physiological responses of beef cattle

Creator:: Cappellozza, Bruno Ieda
Abstract:: Three experiments compared ruminal, physiological, and performance responses of beef steers consuming hay ad libitum and receiving grain-based supplements with (CAM) or without (CO) inclusion of camelina meal. In Exp. 1, 9 steers fitted with ruminal cannulas received CAM (2.04 kg of DM/d) or CO (2.20 kg of DM/d). Steers...

Nutritional characteristics of dormant season grazing within a winterfat (Krascheninnikovia lanata (Gueldenstaedt)) dominated plant community, and the effect of seedbed preparation on the emergence and survival of winterfat and squirreltail (Elymus elymoides (Raf.) Swezey) seedlings

Creator:: Estes, Mark G.
Abstract:: The effect of seedbed preparation on the emergence and survival of winterfat (Krascheninnikovia lanata (Gueldenstaedt)) and squirreltail (Elymus elymoides (Raf.) Swezey)) seedlings was determined, while quantifying nutritional changes through the dormant season for four range species. In November of 2004 twenty 9m x 8m plots were randomly prepared with one...

Nutritional Management of Beef Cows During Late-Gestation to Enhance Offspring Productivity

Creator:: Marques, Rodrigo Da Silva
Abstract:: Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...
