Improving the fermentation ability of unripe air-cured tobacco
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J.G. Nel --- , Republic of South Africa C.R. Wall --- , Republic of South AfricaThe fermentation of dark air-cured tobacco depends on its fermentation ability. Dry spells during the growth period can contribute towards unripe tobacco with poor fermentation ability. By blending such tobacco at a 1:1 ratio with tobacco of good fermentation ability,... -

Research note: The effect of a lactic acid bacterial inoculant on the fermentation dynamics of Eragrostis curvula during ensiling
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: R. Meeske --- , Republic of South Africa H.M. Basson --- , Republic of South AfricaMaking good quality hay from Eragrostis curvula is a risky operation in many areas in South Africa due mainly to unfavourable weather conditions. Ensiling should therefore be considered as an alternative method for conserving the forage. The aim of this... -
Influence of molasses additive and moisture level at ensiling on fermentative characteristics of Panicum maximum
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: WA van Niekerk A Hassen FM BechazSilages made from directly cut or wilted Panicum maximum treated with or without molasses, were evaluated to determine fermentative characteristics. The grass was harvested at the boot stage of growth and the material of each treatment was ensiled in separate... -
Gastrointestinal protozoa and digestive tract parameters of wild South African warthogs (Phacochoerus aethiopicus)
Item type: Journal Article • Journal: African Zoology • Authors: D.G. Booyse --- Department of Anatomy and Physiology, B.A. Dehority --- Department of Animal Sciences,The warthog (Phacochoerus aethiopicus) is a grazer and hindgut fermenter with an apparent unique population of protozoa; however, only a limited number of specimens have been studied to date. In addition to having a very low number of protozoal species,... -
Umami in wine
Item type: Journal Article • Journal: • Authors: Peter Klosse --- Academy for International Hospitality Research, Stenden University, PO Box 1298, 8900 CG, Leeuwarden, The Netherlands Academy for Gastronomy, Amersfoortseweg 86, 7346 AA Hoog Soeren, The NetherlandsThe positive effects of umami on flavour are widely documented, but as far as the author is aware, wines are not mentioned in umami-related literature; vice versa, in wine-related scientific publications, references to umami were not found. In the fermentation... -

The sorghum plant was chopped and treated with different levels of urea (0.1756,... -
Silages in the form of diet based on spineless cactus and buffelgrass
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Alberto Jefferson da Silva Macêdo --- Department of Animal Science, Brazil Edson Mauro Santos --- Department of Animal Science, Brazil Gherman Garcia Leal de Araújo --- Embrapa Semi-arid, Brazil Ricardo Loiola Edvan --- Department of Animal Science, Brazil Juliana Silva de Oliveira --- Department of Animal Science, Brazil Alexandre Fernandes Perazzo --- Department of Animal Science, Brazil Wilma Cristina Cavalcante dos Santos Sá --- Department of Animal Science, Brazil Danillo Marte Pereira --- Department of Animal Science, BrazilThis study was conducted to evaluate the fermentation pattern and the in situ dry matter degradability of silages in the form of diet. Five diets were formulated based on spineless cactus (Opuntia fícus-indica cv. ‘Gigante’) and buffelgrass (Cenchrus ciliaris). The... -
