... The effect of adding steam (at 0.6 and 1.2 bar) and water (1.9% and 64% of the flux of soy grits) in a conventional barrel type conditioner and its effects on protein dispersibility index (PDI), nitrogen solubility in 0.2% KOH and trypsin inhibitor activity (TIA) of commercial soy grits was studied. In addition, conditioned soy grits were subjected to expander treatment at two different screw spee ...

Abstract:
... A commonly used equation for the calculation of the apparent digestibility coefficients of feedstuffs for fish and crustaceans is shown to be incorrect. The correct (but rarely used) equation is presented and contrasted with the previous equation. Data from a previously published trial is used to illustrate the differences between these equations. In many cases the values obtained using the two eq ...

Abstract:
... Apparent digestibility and availability coefficients for beef and bone meal, lamb and bone meal, a high protein meal from mixed species (mixed meat meal, reduced ash, no bones) and from Provine, a high protein meal based on selected ingredients, were determined for juvenile silver perch. Experimental diets comprised a reference diet plus meat meal products at either 15% or 30% inclusion. Silver pe ...

Abstract:
... Nitrogenous waste control in aquaculture systems is necessary to maintain healthy animals and to meet effluent standards. Decreased ammonia production has been attained in traditional livestock production systems by adding extracts of Yucca shidigera to the feed or storage lagoon system. An extract of Yucca shidigera was fed to post yolk-sac and juvenile channel catfish Ictalurus punctatus and hyb ...

Abstract:
... A growth experiment was conducted to investigate the effects of replacement of fish meal (FM) by meat and bone meal (MBM) in diets on the growth and body composition of large yellow croaker (Pseudosciaena crocea). Six isonitrogenous (43% crude protein) and isoenergetic (20 kJ g-1) diets replacing 0, 15, 30, 45, 60 and 75% FM protein by MBM protein were formulated. Each diet was randomly allocated ...
... 1. Increasing proportions of soybeans in poultry diets have highlighted the importance of correct processing to inactivate the anti-nutritional factors present whilst maintaining protein quality. 2. Ground full fat soybeans (FFSB) were extruded using a Clextral laboratory model twin-screw extruder with 0.75 l/h of water and end barrel temperatures of 90, 110, 130 and 160 degrees C resulting in try ...
... The value of soybean [Glycine max (L.) Merr.] is determined in part by functionality of major seed components, extractable oil and high protein meal. Soybean meal is an important protein source for animal feeds, and use of soybean meal by the food industry is increasing. Food allergens have negative impacts for both foods and feeds. The major soybean allergen, Gly m Bd 30K, was identified as the P ...

Abstract:
... Optimum conditions were determined for protein precipitation from acid whey derived from Oaxaca‐type cheese production. Protein precipitation was thermally treated at 93C, with three pH levels (4.60, 4.95 and 5.30) and three heating times (30.00, 37.50 and 45.00 min). The composition of protein concentrate was the response variable and a fourth‐order model was used for the response surface analysi ...

Abstract:
... We compared performance (growth, survival, and condition) of northern largemouth bass Micropterus salmoides salmoides fingerlings fed one of three commercial starter feeds: Otohime Marine Weaning (OMW; Marubeni Nisshin Feed), Bio-Oregon BiVita Fry (BVF; Bio-Oregon), and Purina Aquamax Starter (PAS; PMI Nutrition International LLC). Nine 833-L circular tanks, connected in parallel to a recirculatio ...
... The aim of the study was to determine the yield and chemical composition of milk from TMR-(group I) and pasture-fed Simmental cows (group II). The study was conducted with second and third lactation Simmental cows between 30 and 200 days of lactation. The present research showed that compared to TMR feeding, the use of summer pasture feeding and proper supplementation with high-energy feeds allow ...
... The present study tested antibacterial activity of a rice hull smoke extract (RHSE) against a multidrug‐resistant strain of Salmonella Typhimurium and examined its mode of suppressive action in vitro and in mice. In vitro studies showed that the minimum inhibitory concentration (MIC) value of RHSE was 1.29% (v/v). The inactivation was confirmed by complete loss of cell viability in the range of 10 ...
