The effects of altering forage particle size and source of rapidly degradable carbohydrates on in situ degradation and ruminal variables were studied in four Iranian male sheep. The study was designed...
This experiment was conducted to evaluate the effects of single or multi-particle size limestone on the egg shell quality, egg production, egg quality and feed intake in laying hens. A total of 280 la...
The objectives of this study were to measure particle size and evaluate the effect of increasing alfalfa hay particle size on production characteristics in lactating Holstein dairy cows. Ninety multip...
In this study, we examined production efficiency in broiler chickens fed diets based on three wheat cultivars (Equinox, Regency and Claire) that resulted in different particle spectra (P<0.05) on ham...
We examined gizzard morphology and diet particle size reduction in broiler chickens fed a wheat-based diet that was offered in either a mash or a pelleted form. The pelleted diet had a lower proportio...
This study was conducted to investigate the effect of feed particle size and feed form on growth performance, nutrient metabolizability and intestinal morphology in broiler chickens. This experiment w...
Six dry Holstein cows were used to evaluate the effect of dietary neutral detergent fiber (NDF) concentration and particle size (PS) on chewing activity. Treatments were arranged in a 3횞3 facto...
Two experiments were conducted to determine the effects of reducing particle size of corn from 1,000 to 500 m in simple and complex diets for nursery pigs and broiler chicks. In Exp 1., 192 nursery pi...
