Comparisons of technologies in beef production systems
(2014-05)
Beef steers (n = 180; initial BW = 250 � 19 kg) were randomized to one of two treatments in the pasture phase. Steers were implanted with 40 mg of TBA, 8 mg estradiol, and 29 mg tylosin tartrate (Conventional; CONV-Z) or ...
Influence of oxygen scavenger technology on retail stability of fresh beef in tri-gas master bag packaging
(2020-05)
The objective of this study was to evaluate the effects of three types of O2 scavengers on color stability in a retail environment. Five different products were each placed into a master bag (n = 45) with either a control, ...
Effects of growth-promoting technologies on behavior, mobility, health parameters and heat stress of finishing steers
(2014-07)
Crossbred steers (n=336; initial BW 379 plus or minus 8kg) were used in a RCBD to determine the effects of growth-promoting technologies on steers' behavior, mobility, health parameters and heat stress. Treatments consisted ...
Tenderness, Sensory, and Fatty Acid Attributes of Pasture Versus Grain Finished Beef Aged 14 and 28 Days
(2019-05-01)
The objective of this study was to evaluate the effects of two finishing systems, grain and pasture, and postmortem aging on the sensory, tenderness, display color, and fatty acid profiles of beef from their carcasses. All ...
Effect of winter growing program on subsequent feedlot performance, body composition, carcass merit, organ mass and oxygen consumption in beef steers
(2006-12)
Effect of winter growing program on finishing performance, body composition, carcass merit, organ mass and oxygen consumption of beef steers was investigated. Four steers were randomly selected as an initial harvest group. ...

(2017-12)
Animal manure is one type of organic amendment that is widely used in sustainable agricultural management. It is established that manure affects soil quality, productivity, and biomass, including soil microbiome. Many ...
Prediction of daily water intake of pigs during a 41-day nursery phase
(2021-07)
A total of 3,080 pigs (5.5 to 21.8 kg) were utilized to determine the estimated daily water intake of pigs during a 41-d nursery period. The data set included results from 11 experiments with 28 pens (10 pigs per pen). ...
Effect of rotational grazing on the performance and grazing behavior of cow-calf pairs, and the effectiveness of frequent human interaction in altering the temperament of mature beef cows
(2020-07)
The objective of this study was to evaluate several of the reported benefits attributed to rotational grazing. Rotational grazing (R) was compared to continuous grazing (C), and grazing behavior, forage and diet quality, ...
