Increasing dietary soybean-derived trypsin inhibitor protein compromises nursery pig performance, nitrogen digestibility, and retention.

Trypsin inhibitor proteins, intrinsic to soybeans and soy products, have been found to impair amino acid bioavailability, thereby attenuating pig growth performance. The objective of this experiment was to examine the effect of varying dietary trypsin inhibitor units (TIU) on the performance, nitrogen digestibility, and retention in nursery pigs. Sixty barrows (5.

Increasing trypsin inhibitor concentrations in growing pig diets compromises growth performance and protein digestibility.

Soybeans contain trypsin inhibitor proteins that are antinutritional and may result in growth performance inhibition through reduced amino acid bioavailability. The objective of this experiment was to determine the level of active trypsin inhibitor units (TIU) per milligram (TIU/mg) of complete feed that leads to reductions in growth performance and nitrogen digestibility. Forty-five grower gilts (39.

Increasing dietary soybean trypsin inhibitor protein attenuates nursery pig performance.

Trypsin inhibitor proteins are antinutritional compounds innate to soybeans that reduce protein digestibility, amino acid bioavailability, and growth performance of pigs. The objective of this study was to evaluate the impact of increasing levels of dietary trypsin inhibitor unit activity (TIU/mg) on nursery pig growth performance and health. In a 41-d study, 1,140 newly weaned nursery pigs (5.

Impact of dietary soybean hulls or withdrawal prior to market on growth performance, nutrient digestibility, and carcass characteristics of grow-finish pigs.

In two experimental approaches, this study aimed to evaluate the effects of increasing levels of soybean hulls (SBH) (Exp. 1) and the withdrawal of high SBH from diets prior to marketing (Exp. 2) on growth performance, carcass characteristics, and apparent total tract digestibility (ATTD) of nutrients in grow-finish pigs.

The associations between cardiovascular and pain responses to a cold pressor test differ between males and females.

Nociceptors contribute to the cardiovascular responses during a cold pressor test (CPT). While these responses are lower in females, data suggest that they perceive the CPT as more painful. Thus, we examined sex differences in associations between pain and cardiovascular responses to a CPT (Aim 1) as well as differences between females using (OC), and not using (NC), an oral contraceptive (Aim 2).

Strategies to manage barn feed supply to prolong and hold late finishing pigs during a supply chain disruption.

The U.S. pork production system is sensitive to supply chain disruptions, including those that can create challenges of feed delivery and feed management during the event of a foreign animal disease outbreak.

Eight weeks of inorganic nitrate/nitrite supplementation improves aerobic exercise capacity and the gas exchange threshold in patients with type 2 diabetes.

Patients with type 2 diabetes mellitus (T2DM) have reduced exercise capacity, indexed by lower maximal oxygen consumption (V̇o) and achievement of the gas exchange threshold (GET) at a lower % V̇o. The ubiquitous signaling molecule nitric oxide (NO) plays a multifaceted role during exercise and, as patients with T2DM have poor endogenous NO production, we investigated if inorganic nitrate/nitrite supplementation (an exogenous source of NO) improves exercise capacity in patients with T2DM. Thirty-six patients with T2DM (10F, 59 ± 9 yr, 32.

Hypoxia offsets the decline in brachial artery flow-mediated dilation after acute inactivity.

Intermittent (IH), as opposed to continuous hypoxia (CH), is thought to have beneficial effects on cardiovascular function and health. In the present study, we examined the acute effects of IH and CH (∼80% pulse oxygen saturation via 10% oxygen tank) on peripheral vascular function. Brachial artery flow-mediated dilation (FMD) was used to assess vascular function in 12 young adults (23 ± 5 yr; 8 M/4 F) before and after 50 min of IH (5 cycles; 4-min normoxia/6-min hypoxia per cycle), CH (20-min normoxia followed by 30-min hypoxia), or time control (50-min normoxia) interventions.
