The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.3, 6.9, 48.9, 2.1, 32.4, 83.8% and 23.6 MJ kg, respectively. The average Ca,...

This study was performed in order to evaluate the effect of dried yeast from sugar cane when replacing soybean meal in dairy heifers’ diets. Twenty-four heifers, with an initial body weight (BW) of 178 kg, were distributed in a completely randomized design. The treatments were four levels of inclusion of dried yeast from sugar cane replacing to soybean meal (0, 33, 67 and 100% on a dry matter (...

BACKGROUND: Although the effects of resistant starch (RS) on postprandial glycemia and insulinemia have been extensively studied, little is known about the impact of RS on fat metabolism. This study examines the relationship between the RS content of a meal and postprandial/post-absorbative fat oxidation. RESULTS: 12 subjects consumed meals containing 0%, 2.7%, 5.4%, and 10.7% RS (as a percenta...

In this study, peanut meal was used as the substrate for continuous production of even carbon volatile fatty acids (ECFA) through anaerobic fermentation. First, a stirred reactor (CSTR) started by adjusting initial pH to acclimate related bacteria, and then hydraulic residence time (HRT) optimized. The effects different HRT on potential ECFA fermentation, transformation utilization main organic...

Tilapia are the third most important cultured fish group in the world, after carps and Salmonids. Tilapia culture is also one of the fastest growing farming activities, with an average annual growth rate of 13.4% during 1970–2002. They are widely cultured in about 100 countries in the tropical and subtropical regions. As a result, the production of farmed tilapia has increased from 383,654 mt i...

Many studies with fin fish have demonstrated the potential to use alternative dietary protein sources to fish meal based on growth responses, although these trials mostly neglect to determine if such protein sources affect immune function. This study investigated the effect of fish meal replacement with dehulled lupin meal (LPN) or hydrolysed poultry feather meal (FTH). Atlantic salmon (Salmo s...

the aim of the current study was to evaluate the replacement effect of soybean meal (sbm) at different levels (0 as d1, 33 as d2, 67 as d3 and 100% as d4 based on crude protein (cp) content) by guar meal (gm) on ruminal gas production kinetics, ruminal digestibility and fermentation characteristics of a fattening diet for lambs. three experiments were conducted. the first experiment of 144-h in...
