Character association and inheritance studies of different sorghum genotypes for fodder yield and quality under irrigated and rainfed conditions
Cyanide poisoning is the major problem in sorghum fodder. This poisoning results in livestock mortality and causes economic loss to the people. Some work have been reported on quantity but little work has been focused on quality especially the cyanide content in sorghum fodder in Pakistan. Inheritance mechanism for some fodder yield and quality traits were studied among 25 sorghum genotypes under irrigated...

Utilisation of organic and inorganic nitrogen sources by Scleroderma sinnamariense Mont. isolated from Gnetum africanum Welw.
The ability of Scleroderma sinnamariense Mont. to utilise some organic and inorganic nitrogen (N) sources for growth was examined in axenic liquid cultures. Pisolithus tinctorius Pers. was included for comparison. Both fungi species produced measurable biomass on all the N sources used in this experiment. The growth of S. sinnamariense on ammonium-N was better than that observed...

Population dynamics of Caspian spirlin (Actinopterygii: Cyprinidae) in the Kesselian Stream, Iran
Studies on age, growth, mortality and recruitment of Alburnoides sp. were conducted in Kesselian Stream, South Caspian Sea, Iran from July 2008 to June 2009. Length frequency data were analyzed by using FISAT (FAO-ICLARM Stock Assessment Tools) software for estimating population parameters. Asymptotic length (L∞) and growth coefficient (K) were estimated at 104.48 mm and 1.19/year. Growth...

Detection of Aspergillus spp. and determination of the levels of aflatoxin B1 in rice imported to Bushehr, Iran
Aflatoxins (B1, B2, G1 and G2) are hepatotoxic metabolites produced by Aspergillus flavus on a number of agricultural commodities. Their levels were studied in rice samples imported to Iran through a southern port in Bushehr. Aflatoxins analysis was performed by solvent extraction, immunoaffinity clean-up and determination using high performance liquid chromatography (HPLC) equipped with...

Development of a potential lignocellulolytic resource for rapid bioconversion of rice straw
This study was conducted at the Laboratory of Food Crops and Floriculture, Institute of Tropical Agriculture, Universiti Putra Malaysia to characterize the potential lignocellulolytic bacteria for rapid bio-bioconversion of rice straw. Fifty isolates of bacteria were isolated from several in-situ and in-vitro sources. Isolates B3, B13, B21, B37 and B46 showed the highest enzymatic...

The essential oil composition and antimicrobial activity of leaves of Schistostephium hippifolium
The essential oil from the leaves and branches of Schistostephium hippifolium were extracted by hydro-distillation during summer and winter months. Both essential oils were analyzed by gas chromatography- mass spectroscopy (GC-MS) respectively during their extracted period. Fourteen compounds were identified from essential oil extracted during the February, summer month in South...

Characterization of a cellulase from the haemolymph of the giant African snail (Archachatina marginata)
The giant African snails (Archachatina marginata) are herbivorous tropical gastropods. They are commonly located in areas littered with decaying vegetable matters which they feed on. When the haemolyph of this organism was passed through Sephadex G-200, the resin was digested. The ability of snails to digest vegetable matters and the digestion of Sephadex G-200 resin by the haemolyph led to the suspicion of...

Effect of dietary vitamin E on Eimeria tenella-induced oxidative stress in broiler chickens
An experiment was carried out to investigate the impact of high doses of dietary vitamin E on antioxidant status in broiler chickens (Ross 308) experimentally infected with Eimeria tenella. One day old chicks were assigned to five groups (25 each) and given basal diet (A and B) or basal diet supplemented with 100, 316 or 562 mg/kg of vitamin E (C to E), respectively. On the 21st day, all chicks...
