In the analysis of the purified wax (1) isolated from the human tubercle bacillus it was found that the principal ether-soluble constituent was a hydroxy acid of very high molecular weight which was designated by the term “unsaponifiable wax” (2). This substance has been the subject of further studies, the results of which are reported in this paper. The so called waxes of the human tubercle ba...

the chemical and fermentative parameters of three fresh forages and silages of sorghum including sweet, pegah and speedfeed varieties were compared with corn using in vitro method, also degradability coefficients of forages and silages were determined by in situ method. forages were planted in the same condition and harvested in soft dough stage, then ensilaged in four replicates for each time ...

Five different hays were used to determine the effect of 5 different soaking and steaming treatments on the water soluble carbohydrate and microbial (bacteria and mould) contents of UK hay. Hays were subjected to the following 5 treatments: 1. Dry; 2. Steamed for 50 minutes in the Haygain- 600 steamer; 3. Soaked in water at 16°C for 9 hours; 4. Steamed then soaked and 5. Soaked then steamed. Po...

information on quality characteristics of forage species help the range managers to select a suitable grazing program that minimizes the damages to vegetation. water soluble carbohydrates (wsc) -the main photosynthetic products- are stored in various plant parts and are more likely to be consumed when plants require them. in order to investigate the changes of wsc in distinguishable organs in t...

in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...

drought, ultraviolet radiation and atmospheric co2 are some three environmental factors that seriously affect future food security. the objective followed in the present research was to study the effect of two levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv a, b and c with intensities of 18, 25 and 40 microw.cm-2 respectively) and water deficit (%100 and %60 of field capac...

Strategies of carbon (C) and nitrogen (N) utilisation are among the factors determining plant distribution. It has been argued that submersed macrophytes adapted to lower light environments are more efficient in maintaining C metabolic homeostasis due to their conservative C strategy and ability to balance C shortage. We studied how depth distributions of 12 submersed macrophytes in Lake Erhai,...

Bedouin goats were fed on wheat straw as a single-component diet under two watering regimens, drinking once daily or once every 4 d, in order to clarify whether lignin-degradation products were absorbed, metabolized and excreted in urine. Acid-soluble lignin accounted for 220 g/kg total lignin, its digestibility was the highest (0.87) and was unaffected by water deprivation. Acid-insoluble lign...
