this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...

different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by aspergillus oryzae in submerged fermentation. enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. results ...

Two experiments were conducted to evaluate the effects of irradiated ingredients in meal and pelleted diets on nursery pig performance. In Exp. 1, a total of 192 pigs (initial BW, 6.0 kg) were used in a 25-d experiment. Pigs were blocked by BW and randomly allotted in a 2 x 2 factorial arrangement of treatments with main effects of diet form (meal or pellet) and either irradiated (11.92 kGy) or...

In situ degradabilities were determined for some commonly used grains and by-product feeds in dairy cattle rations. Ingredients evaluated were barley, shelled corn, soybean meal, brewers dried grains, corn gluten feed, distillers dried grains, soybean hulls, and wheat middlings. In situ studies were conducted in three rumen-fistulated Holstein cows. Cows were fed a total mixed Ž . rations conta...

the present study was carried out to investigate the replacement of soybean meal by different levels of canola meal (either with or without canola meal undergoing heat processing). two hundred forty commercial layer hens (lsl strain) at 54th week of age, selected based on the same egg production percentage and body weight. the experimental design was a crd, in a factorial arrangement of 4 repli...

Soybean meal (SBM) was treated with acid or alkali to determine effects on N solubility, in vitro NH3-N accumulation, in situ N degradability, and N digestion and retention in growing lambs. The following SBM treatments resulted in decreased (P less than .05) N solubility and in vitro NH3-N accumulation compared with control SBM: spraying with 2.5 or 5% acetic or propionic acid, soaking in .5 N...

A modified true metabolizable energy bioassay was used to determine the nitrogen-corrected apparent (AMEn) and true (TMEn) metabolizable energy of various feed ingredients for ducks. In each of two experiments, which lasted 102 h with a 54-h excreta collection period following a 48-h period of feed withdrawal, six male White Pekin ducks were assigned to each of three test feed ingredients and d...
