There has been an increasing global demand for large bluegill (Lepomis macrochirus) to supply the food-fish market. Current diets resemble those largemouth bass and contain a high percentage of marine fish meal (FM). Research into use alternative protein ingredients need be conducted not only conserve finite resources, but reduce cost expand We evaluated growth, survival body composition fed in...

Banned Antibiotic in Poultry Feed The U.S. FDA banned the use of fluoro­ quinolone antibiotics in poultry production in 2005 in part due to increased resistance to the drugs among Campylobacter bacteria. But a new study finds evidence that these antibiotics are still being used or are inadvertently contaminating poultry feed. The authors analyzed samples of U.S. and Chinese feather meal, a by­p...

Investigating the Effect of Replacing Soybean Meal with Poultry Slaughterhouse Waste Mixed Rice Bran and Urea on Performance, Blood Rumen Parameters Fattening Lambs

Reduction of feed costs is a major concern of poultry producers. However, replacement of components of a corn-soybean diet with a lower-cost alternative requires the assessment not only of poultry performance and carcass characteristics but also of resulting meat quality. A brief overview of research studies, conducted over the past 10 yr, investigating the effects of alternative poultry feedst...

Feed costs account for nearly 70 to 80% of the total production costs as nearly all ingredients used in feed manufacturing in Botswana are imported. Therefore, complete feeds are expensive and out of reach of smallholder poultry farmers who lack economies of scale and access to credit. This makes the prospects of utilising insects as a source of protein feasible because they are available throu...

Many studies with fin fish have demonstrated the potential to use alternative dietary protein sources to fish meal based on growth responses, although these trials mostly neglect to determine if such protein sources affect immune function. This study investigated the effect of fish meal replacement with dehulled lupin meal (LPN) or hydrolysed poultry feather meal (FTH). Atlantic salmon (Salmo s...

The increased interest in becoming green for consumers and companies is driving groups to develop innovative ways to become more efficient and reduce their waste. Foods past their expiration dates are large sources of waste and are causing food-manufacturing companies to develop waste disposal strategies. Integrating by-products from these companies into animal diets, specifically that of layin...

The objective of this study was to evaluate the apparent total tract digestibility (ATTD), ME, and fecal characteristics of adult dogs and puppies fed raw soybeans (RSB) and their by-products. Six treatments were evaluated: 1 reference diet (REF), based on a maize-poultry by-product meal, and 5 extruded diets containing 70% of the ingredients of the REF diet and 30% of a soybean processed produ...
