This research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. In this experiment, 375 one-day old male broiler chickens (Ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...

37 In coastal forests of the Pacific Northwest, young coniferous plantations typically contain a 38 mixture of planted and natural Douglas-fir (Pseudotsuga menziesii) and western hemlock (Tsuga 39 heterophylla). Swiss needle cast (SNC) disease inhibits the growth of Douglas-fir to varying 40 degrees in these stands, depending on SNC severity. In addition to the value differential between 41 Dou...

this experiment was conducted in order to determine the effects of different dietary growth promoters on growth performance and nutrient digestibility in male broiler chickens. a total of 360 male broiler chicks (day-old ross 308 strain) were distributed into a completely randomized design (crd) having 6 dietary treatments with four replicates and 15 birds in each replicate. experimental treatm...

To characterize the disturbance regime of one type of vegetation, study areas in which relatively small-scale disturbance predominates were chosen in several old-growth mesic forests in the eastern United States. Canopy openings covered 9.5% of total land area. New gaps were formed at an average rate of 1% of total land area per year; old gap area closed at a similar rate primarily by sapling h...

This research was conducted to investigate spatial variability and estimate tree attributes in a plantation forest in the Caspian region of Iran using geostatistical analysis. Sampling was performed based on a 50m?125m systematic grid in a maple stand (Acer velutinum Boiss) 18 years of age using circular samples of 200m2 area. Totally, 96 sample plots were measured in 63 hectares and 14.25 he...

A 21 ac, 28-yr-old water oak (Quercus nigra L.)plantation, on an old-field loessial site in north Louisiana, was subjected to three thinning treatments during the winter of 1987-1988: (I) no thinning, (2) light thinning to 180 dominant and codominant trees/at, and (3) heavy thinning to 90 dominant and codominant trees/at. Prior to thinning, the plantation averaged 356 trees/at and 86@/ac of bas...

A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal di...
