Water and forage intake, diet digestibility, and blood parameters for beef cows and growing heifers consuming water with varying concentrations of total dissolved salts
(2020-12)
As water becomes a more limited resource, efficient water utilization is needed to continue animal production during water scarcity and declining water quality. The objective of this study was to investigate the effects ...
Effects of varying levels of trace mineral supplementation on performance, carcass characteristics, mineral balance, and antibody concentrations in feedlot cattle
(2021-05)
The objective of this experiment was to determine the effects of increasing concentrations of trace minerals (TM) on finishing cattle performance, carcass characteristics, mineral balance, and antibody concentrations. Angus ...
Using whole cottonseed to replace dried distillers grains plus solubles and prairie hay in finishing cattle rations balanced for physically effective neutral detergent fiber
(2022-07)
Two experiments were conducted to determine the effects of replacing prairie hay and dried distillers grains plus solubles (DDGS) with whole cottonseed (WCS) in finishing diets balanced for physically effective neutral ...
Effect of nutrient intake during gestation on estrus of beef cows and postnatal growth and development of calves
(2008-05)
Scope and Method of Study: Effects of treatment of anestrous beef cows with estradiol cypionate at 25 of 50 d after calving on onset of estrus and luteal activity was evaluated in cows that calved with a BCS < 5 or ? 5. ...
Effects of growing programs and beta-adrenergic agonists on gene expression in adipose tissue depots in finishing beef steers
(2009-07)
Scope and Method of Study:
Determining the existence of bunk preference in an automated individual intake system and the effects of increased roughage late in the finishing period on feedlot steer performance, intake, and efficiency
(2020-07)
The objective of the first experiment was to determine the existence of bunk preference and if access to a preferred bunk affects performance, intake, and efficiency of feedlot steers. Angus steers (n = 123; initial BW = ...
Predicting dry matter intake of gestating and lactating beef cows
(2020-12)
In 1996, the NASEM beef cattle committee developed and published an equation to estimate cow feed intake using results from studies conducted or published between 1979 and 1993. The same equation was recommended for use ...
Determining the role of tryptophan, isoleucine and valine in regulation of growth and nutrient metabolism in young pigs
(2022-12)
Tryptophan (Trp), Isoleucine (Ile) and valine (Val) play important roles on variety of physiological processes, but their mechanisms of action on regulation of growth and nutrients metabolism are not fully understood. The ...
Molecular and biochemical basis of dark-cutting beef
(2022-12)
Dark-cutting beef is a meat quality defect where beef fails to have a characteristic bright-red color typical of normal-pH beef. The occurrence of dark-cutting beef is associated with a high muscle pH resulting from defective ...
Analysis of seasonal effects on nutritive value of native forages in the southern Great Plains and its relationship to sampling method
(2022-05)
The objective was to investigate forage value throughout the year using near infrared reflectance spectroscopy (NIRS) while comparing sample types. Samples were collected from tallgrass native range pastures being grazed ...
