FEED GRAINS ARE A GROWING AND SIGNIFICANT MARKET Livestock industries are a major market for grains on Australia’s east coast and a significant market for grain exports from WA and SA. Hafi and Connell (2003) have estimated that 80% of the annual demand for nearly 9 mmt of feed grains (cereals, oilseeds and pulses) is from livestock industries in the eastern states. An analysis of this demand i...

Deoxynivalenol (DON), a mycotoxin produced by Fusarium spp., is a frequent contaminant of cereals. Because of their rich cereal diet, pigs could be exposed to this mycotoxin. Pigs are among the animal species showing the greatest sensitivity to DON. Effects of intermediate to high levels of DON on pigs are well known and include feed refusal, decreased feed intake, and alteration of the immune ...

Experiment 1 consisted in the genetic selection of two divergent lines D+ and Don the basis of AMEn value measured at 3 weeks of age with birds being fed a wheat diet, using the wheat Rialto cultivar characterised by a high in-vitro viscosity value. Significant difference (3413 J/g DM; P< 0.0001) in AMEn between lines reached 29 % on 4 generation. From the experiment 2 consisting in the test of...

Despite the importance of feedstuffs and feed ingredients in the food chain, few studies have analyzed the effectiveness of usual methods for the microbial decontamination of feeds. This work aimed to study the combined effect of temperature and organic acids (formic or lactic) on the inactivation of 10 isolates of Salmonella enterica and Escherichia coli obtained from vegetable feed ingredient...

Aflatoxins are highly toxic compounds that are produced as secondary metabolites by some Aspergillus and Emericella species. Despite huge progress on aflatoxin research during the past 50 years, we have witnessed many cases of food contamination with aflatoxins all over the world. Aflatoxins have mutagenic and carcinogenic effects and they are capable of inducing hepatocellular carcinoma in hum...

Ethanol is mainly produced from sugar cane (Brazil) and corn or other cereals (US), but these sources induced criticisms as for social sustainability, being directly competitive with the food and feed chain. Therefore, a second generation concept was introduced for biofuels, by developing processes for their production from waste biomass or energy crops not competitive with agriculture. However...

Because of the protein content of their seeds, grain legumes, pseudocereals, and other crops are candidates to satisfy the growing demand for plant protein for food and feed. Crop production worldwide is highly specialized and currently relies on a very small number of species, raising questions about the sustainability of farming (Tilman et al., 2002). The role of legumes in nutrition has been...

Poultry diets are formulated primarily using cereals and protein meals (corn, wheat and soybean meal) as the main ingredients. There is noted shift in using coproducts from cereals and oilseeds in poultry diets due to availability and relatively lower cost. However, there is wide variation in the nutritional values of both conventional feedstuffs and coproducts, which creates a necessity of dev...

BACKGROUND Antisecretory factor (AF), a 41 kDa cloned and sequenced protein, suppresses intestinal inflammation and hypersecretion in animals. Endogenous AF production can be induced by dietary modifications in several animal species, and this feed has been shown to reduce the incidence of diarrhoeal disease in weaning piglets. The role of AF in intestinal disease in humans is not known. AIMS...

between SI WRC and IUS was: WRC = 0.0279 IUS + 0.7047 (R2 = 0.654). On the other hand, extrusion of cereals promoted a significant increase in Gastric WRC, probably due to the gelatinization and dispersion of starch. Extrusion and grinding promoted decreases in SI WRC, which was associated with a decrease on the amount of IUS rather than a variation on the feed particle size. Further studies ar...
