The use of pea seeds is limited due to the content of antinutritional factors that may affect gut physiology. Heat treatment such as extrusion may reduce heat-labile antinutritional factors and improve the nutritional value of pea seeds. This study determined the effect of partial replacement of soybean meal in pig diets by raw or extruded pea seeds on growth performance, nitrogen balance and p...

An experiment was conducted to investigate the effects of dietary lipid and inorganic phosphorus supplementation on growth, retention and loading of phosphorus and nitrogen in young red sea bream. Two levels of lipid (190 and 250 g/kg) and two levels of phosphorus (14 and 19 g/kg) in the dry diets were tested. Four practical diets were formulated and coded as L0P0, L0P1, L1P0 and L1P1, respecti...

this experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. for tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. then, pistachio by-products were removed from the water and ...

Vegetable proteins such as soybean meal, canola meal and lupins are widely used as the main protein source in poultry diets. However, there is only limited information on the nutritive or anti–nutritive effects of indigestible non–starch polysaccharides in vegetable proteins. This review discusses a number of experiments which investigated the effects of feed enzymes on the utilisation of non–s...

Chilling of whole rumen contents prior to preparation of strained rumen fluid enriched with particle-associated microorganisms resulted in rumen inoculum with the highest microbial dry weight, total bacterial counts, and degradation rates for casein and soybean meal. Strained rumen fluid, whole rumen contents blended with strained rumen fluid, chilled strained rumen fluid, and strained rumen fl...

Two experiments were conducted to evaluate the nutritional value of three cultivars (Promore, Kiev mutant and Ultra) of white lupins (Lupinus albus L.) for broilers. In experiment 1, the apparent metabolisable energy (AME) and ileal amino acid digestibility coefficients of the three cultivars were determined. The cultivar effects were significant (P < 0.05) for AME, but the ileal amino acid dig...

Layers feeding are a technological factor that could increase economic efficiency in egg production if it is scientifically managed. The increasing price of raw materials used for producing diet imposes as nutritionists to look for new cheaper feedstuff able to replace the traditional and more expensive ingredients like soybean meal. This study aimed to set up new diet formulae for layers feedi...

Ž . The use of a co-extruded soybean poultry by-product meal CEPM and flashed dried poultry Ž . by-product meal FD-PBM was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Each meal was substituted for menhaden Ž fish meal on an iso-nitrogenous basis and offered to juvenile Litopenaeus Õannamei mean initial . Ž wt."S.D., 0.37"0.01...

An experiment was conducted to determine the effects of soybean meal (SBM) particle size on broiler performance, particularly P utilization. This experiment utilized a 2 x 2 x 2 factorial design with the following variables: SBM particle size, P level, and diet type, either corn-SBM or semipurified. SBM was obtained from a processing plant before (geometric mean diameter 1,239 microm) and after...

The nutritional value of raw Jack bean meal (Canavalia ensiformis) as a partial substitute for soybeans meal was investigated in this study. Preliminary investigation on nutrient composition revealed that lysine, histidine, and phenylalanine were significantly higher in C. ensiformis seed meal compared to soybean meal. However, crude protein and other essential amino acids were significantly lo...
