BACKGROUND Body weight (BW) cycling, the yo-yo effect, is generally thought to have adverse effects on human metabolic health. However, human and animal experiments are limited in number and do not provide clear answers, partly due to large variations in experimental design, parameters measured, and definitions of BW cycling. Here, we examined the effect of repetitive BW cycling versus single- ...

Two genetic lines of barrows and gilt pigs with lean BW gain averages of 280 and 375 g/d were used to evaluate their macro- and micromineral contents at BW intervals from 20 to 125 kg of BW. The experiment was a 2 x 2 x 5 factorial arrangement of treatments (i.e., 2 sexes, 2 genetic lines, and 5 BW intervals) conducted in a completely randomized design in 6 replicates using a total of 120 pigs....

A retrospective study was performed to evaluate the relationships between BW at first insemination and subsequent body development, feed intake, reproductive performance, and culling rate of rabbit does. Young rabbit does are vulnerable to body energy deficit in first lactation, resulting in decreased reproductive performance and high replacement rate. Heavy does at first insemination might be ...

BACKGROUND Echocardiography is a cost-efficient method to screen cats for presence of heart disease. Current reference intervals for feline cardiac dimensions do not account for body weight (BW). OBJECTIVE To study the effect of BW on heart rate (HR), aortic (Ao), left atrial (LA) and ventricular (LV) linear dimensions in cats, and to calculate 95% prediction intervals for these variables in ...

This study was conducted to determine the relative contribution of feeding behavior, DMI, apparent DM digestibility (DMD), and passage rate on variation in BW gain. One hundred forty-three crossbred steers were used in this study to determine the factors that contribute to variation in BW gain. Steers were 304 ± 1 d of age and had an initial BW of 338 ± 3 kg. Steers had ad libitum access to fee...

Recent evidence indicates that efficient expression of major histocompatibility complex (MHC) complexes requires their interaction with the resident endoplasmic reticulum (ER) chaperone calnexin, which for certain proteins functions as a lectin specific for monoglucosylated glycans. In the current report, we studied the expression of MHC class I proteins in BW wild type thymoma cells (BW WT) an...
