The effects of herd size, semen type, generation overlapping and breeding goal on genetic gain in Holstein cows were studied through stochastic simulation. Three levels of herd size (100, 200, and 400), two levels of semen type (unsexed and sexed), three levels of generation overlapping (low, average and high) and two levels of breeding goal (narrow and broad) were combined together to make 36 ...
arginine (arg) requirements of male broilers (ross 308) reared at high altitude (2100 mabove sea level) during the 1-to 3-week period was estimated in a graded supplementationmethod, in which six diets (230 g kg-1 cp and 3200 kcal me kg-1) with arg increments of1.25 g kg-1 were applied to four pens of fifteen birds each. dietary arg content of theexperimental groups ranged from 10 g kg-1 (80% o...
Patterns of pregnancy weight gain and predictors of first trimester and total weight gain were investigated in a sample of 1367 women from Cebu, Philippines, with pregnancy intervals of < 2 y. The mean total weight gain based on actual measurements of prepregnant weight was 8.4 kg. Controlling for gestational week when weight was measured, multivariate-regression models predicted higher first t...
purpose weight loss in wrestling has been found to be an interesting issue for researchers. in this regard, complications of weight loss in wrestlers before the competitions and their weight gain in course of competitions have been debated in previous studies. the objective of this study was to investigate the extent of weight gain and to estimate the percentage of body fat in participants in t...
