An experiment was carried out on 384 7d old commercial broiler chicks (Lohman) to study the effect of changes in source and level of dietary calcium and limestone particle size on the performance and tibial growth and calcification of broiler chicks. From day 1 to day 7, the chicks were fed with the commercial basal diet. On day 7, the chicks were weighted and randomly assigned to 64 groups, si...

in the present study, five log-normal models, normal model (n), and two four- parameter models namely gompertz (g) and fredlund (fr) were tested on 71 psd data from 10 soil textural classes. the jaky (j) and fr models had the smallest and largest r2 values for all of the soils, respectively. the results of comparing the n and simple log-normal (sl) models showed that the accuracy of the n model...

Introduction: Determining the size distribution of the particles for assessing their effects on human health and their control mechanisms is very effective. One of the most important equipment used in determining particle size distribution is the DMA. In this study, in addition to the design and construction of a DMA, the size distribution measurement of aerosol particles was carried out. Mate...

The objectives of this experiment were to determine effects of reducing particle size on growth performance, carcass characteristics, stomach morphology, and VFA concentration in the hindgut of growing-finishing pigs if diets were formulated to a constant ME. Thirty-six gilts and 36 barrows (32.00 ± 1.58 kg initial BW) were individually penned and randomly allotted to 4 dietary treatments in a ...
