The objective of this study was to investigate the effect exogenous protease supplementation in diets formulated with poultry by-product meal on growth performance, small intestine magnitudes, and meat physiochemical characters broiler chickens from 21 35 days post-hatch. A total 120, one-day-old "Arbor Acres Plus" (male: female - 50:50) were allocated one two dietary treatments give six replic...

Antimicrobials used in poultry production have the potential to bioaccumulate in poultry feathers but available data are scarce. Following poultry slaughter, feathers are converted by rendering into feather meal and sold as fertilizer and animal feed, thereby providing a potential pathway for reentry of drugs into the human food supply. We analyzed feather meal (n = 12 samples) for 59 pharmaceu...

the aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (pbpm) fed during late gestation on the performance, blood metabolites, and colostrum composition of holstein dairy cows. sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1) 14% and 2) 16% crude protein. the cow’s bcs was 3.56 ...

Approximately 25 to 40% of the DM in premium dog diets is animal by-product. However, limited information is available regarding the composition and digestibility of these by-products, especially small intestinal digestibility. The effects of raw and rendered animal by-products incorporated into dog diets on nutrient digestion at the ileum and in the total tract were studied in this experiment....

The potential use of poultry by-product meal (PBM) and meat and bone meal (MBM) as alternative dietary protein sources for juvenile Macrobrachium nipponense was studied by a 70-day growth trial. Triplicate groups of M. nipponense (initial body weight: 0.37 g) were fed at 20.7-22.4 degrees C on each of the five isoenergetic and isonitrogenous diets (protein content about 38%) with different repl...

Several protein sources were tested as deer repellents with captive deer. Black-tailed deer were offered Western redcedar seedlings treated with corn gluten meal, feather meal, poultry blood, hydrolyzed casein, or a control (latex sticker used for treatment proteins). After 37 days, feather meal and hydrolyzed casein provided equivalent protection against browse damage (only 23% of seedlings si...
