Two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (PB) extract. PB was soaked in water with a ratio of 1:5 (w/v) for 12 h. After filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

The apparent digestibility coefficients of three protein levels of reference diets (without fish meal) and test diets (with fish meal) were estimated for Labeo rohita. Three test diets (test diet-I, test diet-II and test diet-III) and three reference diets (reference diet-I, reference diet-II and reference diet-III) having 28, 30 and 32% protein levels were prepared. Chromic oxide was used as a...

in the first experiment, twelve species of the most plentiful and fresh seaweeds and one species of seagrass from the beach were collected at kingston, south australia. all species were then separately sun-and oven-dried and ground. the ground samples were analysed for dry matter, ash, organic matter, crude protein, crude fibers, ether extract and digestibility in vitro. the digestible and ...

Crude wild pear lipoxygenase (LOX) from ripe Kurdistan wild pears was used in this study. Extracted crude LOX was assayed spectrophotometrically for raw, ripe wild pear lipoxygenase and after 7-day storage. The effects of different buffers and pHs, substrate preparations, temperature, inhibitors and metal ions on LOX activity were evaluated at three conditions. The enzyme was most active with H...

Effects of artificial diets on growth, spawning performance, egg and larval biochemical compositions and quality of Acanthopagrus latus in the Persian Gulf were studied. Nine diets representing a combination of three protein levels (40, 50 and 60%) and three energy levels (22.5, 23.5 and 24.5 MJ GE/Kg) were tested in triplicates. Each tank was stocked with 10 fish with a sex ratio of 1:1 and wi...

this study was conducted to investigate the effect of physical and chemical processing on crude protein fractions of two varieties of canola (okapi and modena) and safflower (62 and zarfan) seed using cornel net carbohydrate and protein system and on protein subunits using sodium dodecyl sulfate polyacrylamide gel electrophoresis. formaldehyde was used as chemical treatment, while toasting and ...
