Finishing precocity visual score selection was adopted to estimate the time from birth to reach slaughter age. This study estimated (co)variance components and genetic correlations for the finishing precocity score at weaning (WP) and yearling (YP) stages by using daily weight gain (BWG = from birth to weaning; WYG = from weaning to yearling) and speed of weight gain (BWR = from birth to weanin...

In an age of increasing numbers of lifestyle diseases and plasticity of longevity, exercise and weight training have been increasingly recognized as both preventing and mitigating the severity of many illnesses. This study was designed to determine whether significant weight-lifting gains could be realized through the Anatoly Gravitational System. Specifically, this study sought to determine wh...

Periodization of resistance training or planned changes in training volume and intensity are used to maximize strength and fitness gains. Several types of periodized resistance training plans have been developed. The most common of these plans is linear also termed classic or strength/power periodization and nonlinear periodization. The biggest difference between these two types of training pla...

Hereford and Charolais steers were fed at three levels of feed intake (low, medium or ad libitum) to similar weights within breed groups to evaluate effects of energy intake on energetic efficiency and body composition. Two methods were employed to partition metabolizable energy intake into use for maintenance and gain. Method one used an assumed daily fasting heat production of 77 kcal/weight ...

Crossbred ewe lambs initially weighing approximately 90 lb (41 kg) were fed rations varying in roughage level prior to breeding to examine the influence of level of dietary energy upon subsequent reproductive performance when bred as lambs. In the two trials conducted over a 2-year period 200 spring-born Iambs were placed in four lots of 25 lambs each year and received rations containing 12% cr...

PURPOSE This study aimed to investigate the relative weight gain at 2-week intervals up to 6 weeks after birth to predict retinopathy of prematurity (ROP) requiring treatment among very low birth weight infants. METHODS A total of 211 preterm infants with birth weights <1,500 g and gestational age <32 weeks were retrospectively reviewed. The main outcome was the development of ROP requiring t...

The authors examine weight gains associated with smoking cessation in the Lung Health Study (1986-1994) over a 5-year follow-up period. A cohort of 5,887 male and female smokers in the United States and Canada, aged 35-60 years, were randomized to either smoking intervention or usual care. Among participants who achieved sustained quitting for 5 years, women gained a mean of 5.2 (standard error...

Three trials were conducted to study the effect of various levels of metabolizable energy (ME) on reproductive performance of crossbred gravid sows from breeding through gestation. One-hundred-one litters resulted from 124 sow matings during two summer and one winter trials over a 1 1/2-year period. Sows were fed 1.3 kg of a basal diet with additions of corn starch to provide 4,000, 5,000, 6,00...
