an experiment was conducted to evaluate the effect of early feed restriction on performance and serum thyroxin concentration of broiler chicks. the experiment was designed in a 2×2 factorial with 5 replicates of floor pens with 12 male or female chicks in each. 240 male and/or female day-old chicks of a commercial strain (hybrow) were wing banded, weighed and randomly allocated to two treatment...
A completely randomized design experiment was conducted to determine the effects of physical form of the diet (pellets or mash) on the growth performance and water intake of broiler chicken. Twenty seven days-old (n=32) broiler chicks were randomly allocated into 8 deep litter cages. Each cage housed 4 birds and contained a feeder and a drinker. Birds in four cages were fed a commercial broiler...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods. For evaluating of protein quality, 90 male broiler chicks in a com...
