The effects of the rate of gain during four periods of growth on carcass characteristics in swine
Records of 176 Hampshire pigs, consisting of 118 barrows and 58 gilts, were used in this study. The least squares method was applied to estimate the effect of rate of gain during four periods of growth (birth to 50 pounds, 50 to 100 pounds, 100 to 150 pounds, and 150 to 200 pounds) on carcass …

The influence of weaning age on growth and development of the baby pig and reproductive efficiency in the sow
Thirty-nine litters containing 385 pigs of mixed breeding were weaned at 1, 7, 14, 21, 28 or 35 days of age in two experiments conducted during the spring and summer of 1966 . A creep ration constituted the only diet from weaning to 56 days with the exception of pigs weaned at 1 or 7 days. These …

Bromide residues in tissues from rats maintained on diets fumigated with methyl bromide
The effect(s) of bromide residues in rat diets on tissue bromide accumulations, organ size, growth rate and physical activity were studied. In Experiment 1, the treatment groups were fed diets containing 290, 600 and 1177 ppm bromide, respectively. The control group received 36 ppm from untreated …

An Analysis of Carcass, Ultrasonographic, and Projected Measurements of Feedlot Animals to Determine the Benefits and Accuracy of Harvest Groups Vs. Visual Selection
Ultrasonic measures of fat thickness (FTU) and percent fat (PFATU) were taken on Hereford steers (n = 49) and heifers (n = 2) ranging in age from 10 to 20 months in a production setting in central Missouri and used to evaluate carcass attributes and slaughter readiness. This information also …
