APPLICATION OF CHEMOMETRICS TO PREDICT INTAKE AND FEED EFFICIENCY USING FEEDING BEHAVIOR PATTERNS IN GROWING CATTLE

Johnson, Jocelyn Rose (2019-07-26)

Residual feed intake (RFI) is an ideal trait for use in selection programs to improve feed efficiency in beef cattle, as it quantifies between-animal variation in DMI that is independent of body size and productivity, to ...

Characterization of Feed Efficiency Traits and Relationships with Temperament, Serum Hormones and Serum Metabolites in Growing Brangus Heifers

Gomez, Robynne 1977- (2010-09-03)

Physiological traits that are biologically associated with feed efficiency may be useful indicator traits residual feed intake (RFI). The objective of this study was to examine the relationships between RFI, temperament, ...

Development of a Mathematical Model for Predicting Digestible Energy Intake to Meet Desiered Body Condition Parameters in Exercising Horses

Zoller, Jennifer Leigh (2016-12-08)

Information regarding dietary requirements to maintain or alter body condition in the horse is scarce; however, a recently developed nutritional model was acceptably accurate in prediction of the energy required to alter ...

Effects of Multi-valent Vaccine Treatment and Temperament on Feed Intake, Performance, and Feeding Behavior Responses to BVD Viral Challenge in Beef Steers

Smith, Paul Stephen (2017-08-24)

The objectives of this study were to examine the effects of vaccine treatment (VT) and temperament on DMI, performance, and feeding behavior responses to a BVD viral challenge. Nellore-Angus crossbred steers (N =360; initial ...

Energy Expenditure in Growing Heifers with Divergent Residual Feed Intake Phenotypes. Effects and Interaction of Metaphylactic Treatment and Temperament on Receiving Steers

Paddock, Zachary Dean (2011-10-21)

Cattle classified as having low residual feed intake (RFI) phenotypes are those that consume less feed than expected based on body weight and growth performance. Mechanisms contributing to the variation in RFI are not ...

Examining Mechanisms Contributing to the Biological Variation of Residual Feed Intake in Growing Heifers and Bulls and in Mid-Gestation Females

Hafla, Aimee (2012-10-19)

The objectives of this study were to characterize residual feed intake (RFI) in growing bulls and heifers and in mid-gestation females to examine relationships with performance, body composition, feeding behavior, digestibility ...

An Exploration of Biological Mechanisms that Impact Intake and Feed Efficiency in the Grazing Animal

Wiley, Leanne (2013-05-21)

Biological mechanisms that potentially contribute to residual feed intake (RFI) have not been fully understood in the grazing animal. The objective of this study was to determine the differences of RFI measured in confinement ...

Nutritional Programming of Puberty in Beef Heifers

De Carvalho Cardoso, Rodolfo (2014-06-26)

Nutritional and metabolic statuses during postnatal development control the timing of pubertal maturation in mammals. Studies reported herein had two overall aims. In Aim I, objectives were to characterize functional and ...

Relationship between the Rumen Microbiome and Residual Feed Intake-Efficiency of Brahman Bulls Stocked on Bermudagrass Pastures

McCann, Joshua; Wiley, Leanne; T. David Forbes; Rouquette, Francis; Jr; Tedeschi, Luis (PloS One, 2014)

Ruminant Methanogenic Activity in the United States Beef Cattle Industry

Klopatek, Sarah B (2016-05-24)

In the U.S., gastrointestinal fermentation from cattle is estimated to account for approximately 25% of total anthropogenic related methane (CH4) emissions. In addition, 2-8% of gross energy consumed by cattle is lost in ...

Understanding Consumer Perception of Beef Through the Development of Tenderness and Juiciness Thresholds, Statistical Modeling, Traditional Liking Questionnaires, Eye Tracking, and Facial Expression Software

Martinez, Hillary Augusta (2019-12-05)

Understanding factors that drive and motivate consumers requires a multidisciplinary approach. As technology advances and statistical tools develop, new methods may be developed to better understand consumer opinion of ...
