In two experiments, 720 broiler strain cockerels were used to determine the effect of pressure and temperature on poultry offal meal (P.O.M.) quality. Poultry offal meals were subjected to 20, 28 and 35 pounds per square inch gauge (p.s.i.g.) steam pressure for <1 or 15 minutes (Experiment 1) and 15, 30 and 45 p.s.i.g. steam pressure for 15 or 30 minutes (Experiment 2). All pressures were allow...

The recycling of rendered animal products back into the feed of ruminant livestock species has had a positive impact both on the efficiency of livestock production and the availability of meat and milk for consumers at an affordable price. Rendered animal products are distinguished by a high protein content containing amino acids that resist microbial degradation in the rumen, and for extracted...

This study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (P-PB) on in vitro gas production using fistulated sheep. One portion of P-PB was mixed with four portions of water for 48 h. The extracted product was sprayed on soybean meal (SBM) or canola meal (CM) with an equal ratio (1:1 v/w) and dried in the shade. The expe...

Insects have been proposed as a high-quality, efficient and sustainable dietary protein source. The present study evaluated the protein quality of a selection of insect species. Insect substrates were housefly pupae, adult house cricket, yellow mealworm larvae, lesser mealworm larvae, Morio worm larvae, black soldier fly larvae and pupae, six spot roach, death's head cockroach and Argentinean c...

Fuel ethanol production is one of the fastest growing segments in American agriculture. Currently, there are 83 ethanol plants in production, with an additional 16 ethanol plants under construction. These ethanol plants have production capacity of 4.3 billion gallons of ethanol per year (Renewable Fuels Association, December, 2004). Approximately 40% of fuel ethanol is produced by wet-mills, an...
