The current study evaluated the effect of a commercial wheat-maizesoybean meal based diet supplemented with an organic acid product containing a specific combination of formic and propionic acids (pHorce) on performance parameters in broiler chickens. One day-old broiler chickens (Ross 308) were randomly allotted to 2 treatments with 10 replicate cages/treatment and 2 birds/cage from d 1 to 21....

Within a simple model of non-localized, Hotelling-type competition among arbitrary numbers of media outlets we characterize quality and content of media under different ownership structures. Assuming advertising-sponsored, profit-maximizing outlets, we show that (i) topics sensitive to advertisers can be underreported (self-censored) by all outlets in the market, (ii) self-censorship increases ...

Two experiments were conducted to study the effect of phytase supplementation to lowphosphorus starter and finisher broiler diets on mineral utilization and growth performance.

In Experiment 1, four replicate groups of 15 commercial broiler chicks, one-day old, were randomly assigned to each of two dietary treatment...
