Abstract

A study was conducted to evaluate the use of deuterium oxide (D2O) for in vivo estimation of body composition of diverse types of pigs. Obese (Ob, 30) and contemporary Hampshire X Yorkshire (C, 30) types of pigs used in the study were managed and fed under typical management regimens. Indwelling catheters were placed in a jugular vein of 6 Ob and 6 C pigs at 4, 8, 12, 18 and 24 wk of age. The D2O was infused (.5 g/kg body weight) as a .9% NaCl solution into the jugular catheter. Blood samples were taken immediately before and at .25, 1, 4, 8, 12, 24 and 48 h after the D2O infusion and D2O concentration in blood water was determined. Pigs were subsequently killed by euthanasia injection. Contents of the gastrointestinal tract were removed and the empty body was then frozen and later ground and sampled for subsequent analyses. Ground body tissue samples were analyzed for water, fat, N, fat-free organic matter and ash. Pig type, age and the type X age interaction were significant sources of variation in live weight, D2O pool size and all empty body components, as well as all fat-free empty body components. Relationships between agemore »« less

Relationships between age and live weight or weight of empty body components, and between live weight, empty body weight, empty body water or D2O space and weight of empty components were highly significant but influenced, in most cases, by pig type. The results of this study suggested that, although relationships between D2O space and body component weights were highly significant, they were influenced by pig type and were little better than live weight for the estimation of body composition.},

Efficacy of deuterium oxide to estimate body composition of growing swine

Journal Article Shields, Jr, R; Mahan, D; Byers, F - J. Anim. Sci.; (United States)

An experiment involving 73 pigs was conducted to evaluate the efficacy of the deuterium oxide (D/sub 2/O) dilution procedure for in vivo estimation of body composition in swine. Pigs were infused with known quantities of D/sub 2/O at 6.4 and 18 kg and then at approximately 18 kg increments to 145 kg body weight. Postinfusion blood D/sub 2/O concentrations were partitioned into early- and total-equilibrating pools. Results from D/sub 2/O analyses were compared with empty (ingesta-free) and total body water values obtained from chemical analysis of the ground animals. Both early- and total-equilibrating D/sub 2/O pools seemed to be goodmore »« less
Deuterium oxide dilution kinetics to predict body composition in dairy goats

Journal Article Brown, D; Taylor, S - J. Dairy Sci.; (United States)

Body composition and D2O dilution kinetics were studied in 15 female goats ranging from 38.0 to 70.1 kg live weight. Infrared spectrophotometric analyses of blood samples drawn during the 4 d following D2O injections were used to estimate D2O space. All does were slaughtered without shrinking and analyzed for dry matter, fat, nitrogen, and ash content. Estimates of D2O space from the late slope of the dilution curve, together with live weight, were used to predict body composition. Conclusions were 1) deuterium oxide space with live body weight accounts for about 90% of the variation in dairy goat empty bodymore »« less

Proposed mechanism(s) of transitory ischemic injury to myocardium

Journal Article Schneider, M; Kelman, B - Am. J. Vet. Res.; (United States)

The main objective of this study was to produce primary acute ischemic injury to myocardium in a live animal. In vitro, guinea pig platelets were sensitive to perturbation and aggregation by a suspension of ultrafine fibrillary collagen material isolated from the aorta of an aged burro (Equus asinus). The platelets responded to this material down to 100 to 200 ng (dry weight) added to 0.45 ml of platelet-rich plasma, as determined by aggregometric technique. Aortic fibrillary collagen material injected IV into guinea pigs circulating platelets within 5 minutes. In blood samples taken 2.5 hours after injection, 50 to 75% ofmore »« less
A New Method of Selective, Rapid Cooling of the Brain: An Experimental Study

Journal Article Allers, Mats; Boris-Moeller, Fredrik; Lunderquist, Anders; ... - Cardiovascular and Interventional Radiology

Purpose. To determine whether retrograde perfusion of cooled blood into one internal jugular vein (IJV) in the pig can selectively reduce the brain temperature without affecting the core body temperature (CBT). Methods. In 7 domestic pigs, the left IJV was catheterized on one side and a catheter placed with the tip immediately below the rete mirabile. Thermistors were placed in both brain hemispheres and the brain temperature continuously registered. Thermistors placed in the rectum registered the CBT. From a catheter in the right femoral vein blood was aspirated with the aid of a roller pump, passed through a cooling device,more »« less

Glucose kinetics in gluconeogenesis-inhibited rats during rest and exercise

Journal Article Turcotte, L; Rovner, A; Roark, R; ... - American Journal of Physiology; (USA)

To evaluate the role played by gluconeogenesis in blood glucose homeostasis, female Sprague-Dawley rats were injected with mercaptopicolinic acid (MPA), a gluconeogenic inhibitor. Glucose kinetics were assessed by primed, continuous infusion of (U-14C)- and (6(-3)H)glucose via an indwelling jugular catheter at rest and during submaximal exercise at 13.4 m/min on level grade. Blood samples were taken from carotid catheters and analyzed for glucose and lactate concentrations and specific activities. Tissue glycogen samples were obtained from rats after exercise as well as from unexercised animals. When compared with the sham-injected animals, MPA-treated animals had 22% lower (5.92 +/- 0.36 vs. 7.62more »« less
