Abstract The objective of this study was to comparatively analyse the physical parameters, basic chemical composition and macro- microelement content offal obtained from fattening pigs raised in deep litter slatted floor housing systems. experiment involved a group 80 Puławska fatteners, including 40 kept deep-litter pens (group I) without bedding II). Offal (tongues, kidneys, hearts, lungs liv...

Three chick experiments were conducted to investigate possible explanations for why pork liver provides no bioavailable Cu to chicks. Autoclaving, acid-hydrolysis, and protease-digestion increased (P < .01) Cu bioavailability in pork liver to 32, 46, and 63%, respectively, from virtually 0% of the Cu in unprocessed pork liver (relative to CuSO4, which was set at 100%). Addition of EDTA at 200 m...

Two experiments were conducted using direct method to determine the standardized ileal phosphorus (P) digestibility coefficient (SIPDC) of meat and bone meal (MBM) poultry byproduct (PBM) for broilers. In first experiment, three MBM from different batches evaluated, with four treatments (MBMI, MBMII, MBMIII, a P-free diet) nine replicates seven birds each, totaling 252 distributed across comple...

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...

Shea nut meal is a by-product of the shea fat industry in West Africa. The objective was to determine the effect of shea nut meal fermentation using Aspergillus niger on growth performance of broiler chickens. An expeller shea nut meal was fermented in a closed plastic container for 8 d after the addition of 0.25 g of A. niger spores per kg of shea nut meal in 2 parts of water. Each of the 2 sh...

Limited information is available on digestibility of nutrients in various practical ingredients used in diets for commercially important finfish species, such as hybrid striped bass. This information is especially needed for sunshine bass, Morone chrysops 3 M. saxatilis, to improve least-cost diet formulations and to allow effective substitution of feedstuffs. A study was conducted with large (...

for their nutritional content. The metabolizable energy of the samples (nitrogen corrected) could be predicted fairly accurately from the ash and protein 'contents of the ingredients. PBPM samples of relatively high and low qualities were incorporated into corn and soybean meal-based diets at the 5% level on an isoenergetic and isonitrogenous basis. Significant differences in chick growth or fe...

Previous results indicated that performance of chicks fed a high level (10%) of poultry by-product meal(PBM) was lower than performance of chicks fed a corn-soybean meal (SBM) diet. The latter difference was hypothesized to be due to variation in digestible amino acid (AA) levels among the diets. This study evaluated diets containing PBM formulated on equivalent total AA basis vs. an equivalent...
