Glucose and fatty acids have long been regarded as the primary sources of energy for the absorptive epithelial cells (enterocytes) of the avian small intestine. However, little is known about the use of amino acids for ATP production in these cells. Based on studies with mammalian enterocytes, we hypothesize that aspartate, glutamate, and glutamine...

Euthanasia is a moral obligation of all individuals working in the swine industry. A majority of acceptable methods have been validated for market weight pigs, while less attention has focused on heavy-weight mature boars and sows. The objectives of the current study were to evaluate the effectiveness of a mobile electric stunner (E-STUN) as a meth...

Feeding sows sugar beet pulp (SBP) has many known benefits, for example, increased satiety, and it is a highly fermentable fiber source for sows. This study investigates how efficient sows utilize energy for fat and protein retention in response to increased SBP inclusion in the diet. After a demanding lactation, sows need to restore body fat and c...

Understanding which dietary amino acids (AA) may impact the release of gut hormones involved in the modulation of feed intake, such as cholecystokinin (CCK) and glucagon-like peptide 1 (GLP-1), can help improve pig feed formulations. The series of studies presented assessed the effect of the 20 proteinogenic non-bound AA on the secretion of CCK and...

An allele of PLAG1 genotype had a significant and positive relationship with Brahman heifer fertility, although the effect on fertility diminished as cows aged. While there was no effect of PLAG1 genotype on growth, there was a significant and negative relationship of the allele improving heifer fertility with mature cow weight.

Indoor group housing using automatic feeders was the most labor-efficient system investigated. All calves displayed positive health and growth indicators; however, behavioral patterns of calves housed individually outdoors may suggest compromised well-being.

Estimation of variance components is becoming computationally challenging due to the increasing size of genomic information. We investigated the impacts of using the algorithm for proven and young (APY) in genetic evaluations. The use of APY has no impact on variance components and genetic parameters estimation.

Titanium dioxide is a marker fed to animals to help determine diet digestibility indirectly by measuring the concentration of TiO2 in fecal samples. This paper describes an accurate and precise method to analyze TiO2 in equine feces. The precision of this method is demonstrated by the low variation between sample duplicates. This method requires fe...

We hypothesized that lubabegron fumarate (Experior, Elanco, Greenfield, IN) would act as an antagonist to β-adrenergic receptor subtypes in primary bovine backfat (subcutaneous) and marbling (intramuscular) adipocytes differentiated in culture. Fat cells were isolated from marbling of longissimus muscle and overlying backfat. In backfat cells, luba...
