Biotech crops have now been grown commercially on a substantial global scale since 1996. This paper examines the production effects of the technology and impacts on cereal and oilseed markets through the use of agricultural commodity models. It analyses the impacts on global production, consumption, trade and prices in the soybean, canola and corn sectors. The analysis suggests that world price...

In this study, cellulase, endoglucanase, and ?-glucosidase activity produced by three fungal strains (Aureobasidium pullulans, Neurospora crassa Trichoderma reesei) were determined on differently processed canola substrates [hexane extracted meal (HECM), washed HECM (WHECM), seed sprout (CSM)] in mono- co-culture fermentation under solid- submerged- state processes. Results showed that the inoc...

Fifty-four Holstein bulls were blocked by initial BW (301 +/- 7.4 kg) and randomly assigned to 6 treatments following a 3 x 2 factorial arrangement, with 3 concentrate lipid levels (5, 8, and 11% of DM) and 2 lipid sources (whole canola seed and whole linseed), with the objective of evaluating the possibility of increasing the content of n-3 fatty acids in meat. Concentrates (mostly corn meal) ...

the cornell net carbohydrate and protein system (cncps) model has recently been increasingly employed in preparation of balanced feed ration of dairy cattle in iran. however, a lack of appropriate characterization of the feeds has restricted the model's application. this study was conducted to evaluate the protein contents of some feedstuffs (wheat bran, sugar beet pulp, soybean meal, cott...

background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

Performance of ruminants is influenced by the proportion of nutrients in their daily feed intake. Protein and energy are the main determinants in the ruminant feed that can alter the animal’s performance. However, in developing countries ruminants are mainly fed on crop residues generally receiving only 62% of their crude protein (CP) requirements (Sarwar et al. 2002). Feeding ruminants accordi...
