Chesapeake Bay has been the subject of intensive research on cultural eutrophication and extensive efforts to reduce nutrient inputs. In 1987 a commitment was made to reduce controllable sources of nitrogen (N) and phosphorous (P) by 40% by the year 2000, although the causes and effects of eutrophication were incompletely known. Subsequent research, modeling, and monitoring have shown that: (i)...
OBJECTIVE This study was conducted to evaluate various wheat supplementation levels on growth performance, blood profiles, nutrient digestibility, and pork quality in growing-finishing pigs. METHODS A total of 120 growing pigs ([Yorkshire×Landrace]×Duroc), with an average 27.75± 1.319 kg body weight, were used in growth trial. Pigs were allotted into each treatment by body weight and sex in 4...
The present study was undertaken to evaluate the effects of soybean varieties on content of anti-nutritional factors, growth, and nutrient digestibility in rat. For this purpose, the content of trypsin inhibitor and lectin was firstly measured in five soybean varieties. Then sixty male Wistar rats were randomly divided into six groups and fed on different diets as follows: groups 1 to 5 were fe...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
Plants absorb nutrients needed for plant type, growing season, depending on soil and yield. Absorb of nutrient 30-90 percent depends management practices in the use of fertilizer. Can be used fertilizers in most cases soil and for foliar feeding can be quickly absorbed into the plant at the proper levels of nutrition in cucumber. In this experiment, was used a split plot in a randomized complet...
The study was planned to determine the comparative efficacy of leaf extract of Azadirachta indica, Cichorium intybus and Moringa oleifera, on haematology, intestinal histomorphology and nutrient digestibility in broilers. Day old broiler chicks (n=180) purchased from a commercial hatchery were reared in a group for one week (adaptation period). At day 8, these birds were individually weighed an...

The effects of four prebiotics (fructo-oligosaccharide, Bio-MOS, transgalacto-oligosaccharide and GroBiotic-A) on digestive enzymes and intestinal morphology were studied in juvenile hybrid striped bass (Morone chrysops × M. saxatilis) and red drum (Sciaenops ocellatus) using two separate 8-week feeding trials. Red drum were fed experimental diets with the four prebiotics each individually supp...
