background: mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. these fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. the aim ...
Mycotoxins affect poultry production by being present in the feed and directly causing a negative impact on bird performance. Carry-over rates of mycotoxins in animal products are, in general, small (except for aflatoxins in milk and eggs) therefore representing a small source of mycotoxins for humans. Mycotoxins present directly in human food represent a much higher risk. The contamination of ...
The poultry industry in the United States faces numerous challenges that both directly and indirectly impact the sustainability of the nation’s poultry production systems. The intensive selection for fast growth and high feed efficiency in modern-day birds has been accompanied by a weakened immune system, increased disease susceptibility and dependence on in-feed antibiotics. Consumers have voi...
The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environm...
Effects of addition of a mycotoxin detoxifier in poultry feed were studied in broilers. Aflatoxins were present in the poultry feed as 28 ppb (normal feed), 78 ppb (contaminated feed) and 170 ppb (highly contaminated feed). The mycotoxin detoxifier was used in 3 concentrations i.e. 1, 3 and 5 kg/ton of feed. Aflatoxins reduced the body weight in broiler chicken and treatment of contaminated fee...
This paper gives recognition to the recent rapid technological, scientific and industrial changes that have taken place in the poultry sector, and uses these as a baseline for the prediction of future trends in nutrition. It is predicted that elevated levels of poultry feed will be required, in the fast-developing poultry sectors of Asia in particular, to meet the burgeoning consumer demand for...
in this study, we investigated the effect of savory (satureja hortensis) essential oil, garlic(allium sativum) powder, and garlic aqueous extract on fungal load of poultry feed. tothis end, savory essential oil and garlic aqueous extract each amounting 62.5, 125, and250 μl/ml and mg/ml, respectively, per kilogram of feed and garlic powder amounting2.5, 5, and 10 g/kg of feed were used. one and ...
Feed related costs are the main drivers of profitability of commercial poultry farms, and good nutrition is mainly responsible for the exceptional growth rate responses of current poultry species. So far, most research on the poultry feeding behaviour addresses the productivity indices and birds’ physiological responses, but few studies have considered the biomechanical characteristics involved...
