Poultry feathers, consisting largely of keratin, are a low-value product of the poultry industry. The safety and digestibility of a dietary protein produced from keratin (KER) was compared to a cysteine-supplemented casein-based diet in a growing rat model for four weeks. KER proved to be an effective substitute for casein at 50% of the total dietary protein, with no changes in the rats' food i...

Along the plant ingredients, rendered animal protein sources such as blood meal, meat and bone meal and poultry by-product meal have potential to be replaced by fishmeal in rainbow trout feed. Therefore, the main objective of the present study is to determine the effect of full replacement of fishmeal by poultry by-products meal (PBM) on fish performance, nutrient digestibility and also liver c...

Propionic acid (PA) is a fungicide and bactericide, registered to control fungi and bacteria in stored grains, hay, grain storage areas, poultry litter, and drinking water for livestock and poultry. European Union (EU) certifies PA as the great of grain preserver and most efficient in controlling Salmonella and other pathogens.

Background: Since the prohibition of antibiotic growth promoter in poultry ration by the European Union, poultry producers have been  trying to replace them by other growth promoters like medicinal herbs. Lipia citridora is a medicinal  herb enriched by several powerful phenolic compounds and with antioxidant and antimicrobial properties which lead to enhancing appetite and growth performance o...

Population diets have impacts on both human and planetary health. This research aims to optimise a New Zealand (NZ) version of the EAT-Lancet diet model impact this population health if it was adopted in NZ. The optimisation methods used mathematical equations Excel ensure: met nutritional recommendations; diet-related greenhouse gas (GHG) emissions did not exceed NZ GHG boundary; costs baselin...

In Cambodia, influenza A(H5N1) virus surveillance at live poultry markets (LPMs) relies on virus isolation from poultry specimens; however, virus is rarely detected by this method. We tested 502 environmental LPM samples: 90 were positive by PCR, 10 by virus isolation. Virus circulation could be better monitored by environmental sampling of LPMs.

Distillers dried grains with solubles (DDGS) is a corn derived co-product of the ethanol industry. Recent renewable fuels legislation is encouraging more production of ethanol, thus using more corn but resulting in greater supplies of DDGS available for animal feeding. As corn prices increase some relief could be provided by feeding DDGS as it would replace some corn and soybean meal in poultry...

Background: Some medicinal plants can stimulate growth in poultry. Objective: To compare the effects of dietary addition virginiamycin antibiotic and galbanum plant (Ferula gummosa) on performance, carcass characteristics, immune system, blood factors broiler chickens. Methods: A total 250 one-day-old male Ross 308 chickens were randomly assigned to five treatments with replicates (10 birds per...
