the effect of levels of nitrogen on growth and nitrogen uptake patterns and grain protein quality of grain sorghum was investigated by two experiments which were conducted at pakdasht-tehran in 2003. in a completely randomized design with three replications, grain sorghum (sorghum bicolor (l.) moench) hybrid h-726 was grown under greenhouse conditions using water culture technique. the first ex...

In the course of the nutrition investigations in this laboratoq m-e have occasion to make a great many estimations of fat in samples of portions of animals and in feeding stuffs. The usual Soxhlet extraction of the thoroughly dried sample with ether is the method that has been employed. It is understood that this method gives a determination of the crude fat or total ethersoluble material. By t...

Fruits of Broussonetia papyrifera from South China were analyzed for their total chemical composition, and antioxidant activities in ethanol and aqueous extracts. In the fruit of this plant, the crude protein, crude fat and carbohydrates was 7.08%, 3.72% and 64.73% of dry weight, respectively. The crude protein, crude fat and carbohydrates were 15.71%, 20.51% and 36.09% of dry weight, respectiv...

The effects of acidic polysaccharides purified from Gastrodia rhizome on blood pressure and serum lipid levels in spontaneously hypertensive rats (SHR) fed a high-fat diet were investigated. Acidic polysaccharides were purified from crude polysaccharides by DEAE-Sepharose CL-6B. Thirty-six male SHR were randomly divided into three groups: Gastrodia rhizome crude polysaccharide (A), acidic polys...

Ackee canners often harvest mature fruits that are placed on sun racks to complete ripening (indicated by podopening). It is unknown whether the nutrient composition of rack-ripened fruits differs from those completely ripened on trees. This study compares proximate, mineral and fatty acid composition of raw, mature arils of tree-ripened and rackripened fruits. Proximate and mineral composition...

Porang (Amorphophallus muelleri) is a tuber plant that contains lot of glucomannan fiber. Glucomannan soluble fiber can form gel mimics the characteristics fat so it has potential to be used as replacer in high-fat products such cookies. The purpose this study was determine effect using on sensory acceptability and steps carried out were concentration porang flour (5 7.5%). Fat with firmness cl...

To determine the effect of Dietary Crude Protein (DCP) on milk production and protein metabolism, a two group pre/post experimental design was used. The CP level in the ration fed to the two groups (high, low) of lactating dairy cows was increased by 2% for a period of 21 days. Data from each group was collected regarding manure scores, milk fat, milk protein, Milk Urea Nitrogen (MUN) and overa...
