Four experiments involving 3- to 4-wk-old, ad libitum-fed weanling pigs (n = 809) were conducted to determine the effects of initial pig weight, co-mingling of litters, numbers of pigs/pen and room temperature on pig performance in a conventionally equipped nursery. Pigs that were largest at birth were largest (P less than .01) at weaning (r = .66) and also at 28 d postweaning (r = .62). Light-...

The purpose of the heifer herd is to provide replacements for cows leaving the herd and to improve genetic progress. First-lactation cows significantly contribute to herd production and profit. A recommended goal for dairy replacement heifers is to calve at 24 months of age with a targeted postcalving body weight of 1250 pounds. A common misconception is that this goal is either unattainable or...

The main aim of the study was to compare the rearing effect of calves kept outdoor in individual hutches and indoor in group pens. During the experiments, the following measure ments were carried out: body weight, daily gains, feed intake, morbidity and mortality. The study was conducted on 90 calves from 5th to 90th day of age; all calves were fed the same feed and according to the same schedu...

CONTEXT Repletion of lean body mass (LBM) that patients lose in human immunodeficiency virus (HIV) infection has proved difficult. In healthy, HIV-seronegative men, synergy between progressive resistance exercise (PRE) and very high-dose testosterone therapy has been reported for gains in LBM and muscle strength. OBJECTIVE To determine whether a moderately supraphysiologic androgen regimen, i...

BACKGROUND Because pregnant African American women and teens are at risk of low birth weight, they are frequently counseled to strive for gestational weight gains at the upper limits of the Institute of Medicine's recommended ranges. OBJECTIVE The objective was to examine whether such weight gains improve birth outcomes in a cohort of disadvantaged African American adolescents of low (<19.8),...

BACKGROUND There are limited data about whether patients who receive initial treatment for differentiated thyroid cancer (DTC) gain or lose weight during long-term follow-up under thyroid stimulating hormone (TSH) suppression. This study was aimed to evaluate whether DTC patients under TSH suppression experience long-term weight gain after initial treatment. We also examined the impact of the r...

The factors influencing weight changes during the grazing season of Brown Swiss autumn-calving cows and Brown Swiss and Pirenaica spring-calving cows and their calves were studied over an 8-yr period in Spanish mountain conditions. The data set comprised 552 annual production cycles of cows that calved in two consecutive years. The animals grazed on alpine ranges during the summer and on forest...

Background: The timing of maternal weight change in pregnancy may be an important determinant of birth weight. The objective of this study was to measure weight gain patterns from early pregnancy until delivery, and to examine the relationship between prenatal weight gain and low birth weight. Methods: A total of 500 pregnant women within 15-20 days of conception, with confirmed pregnancies and...
