Proposed mechanisms for enzymes as modifiers of ruminal fermentation
Beauchemin and Rode (1996) recently reviewed the use of enzymes in ruminant diets, however, enzymes in the form of crude whole fungal cell preparations have been used to enhance ruminant production for many years. This paper aims to investigate the similarities between the emerging feed enzymes and fungal feed additives, and to use this information to speculate on potential modes of action of d...
متن کاملRuminant Nutrition Symposium: Improving cell wall digestion and animal performance with fibrolytic enzymes.
This paper aimed to summarize published responses to treatment of cattle diets with exogenous fibrolytic enzymes (EFE), to discuss reasons for variable EFE efficacy in animal trials, to recommend strategies for improving enzyme testing and EFE efficacy in ruminant diets, and to identify proteomic differences between effective and ineffective EFE. A meta-analysis of 20 dairy cow studies with 30 ...
متن کاملExogenous enzymes in nutrient digestion and health of non-ruminant: Carbohydrases enzyme
Not all nutrients in farm animal’s diet are fully digested by animals own digestive enzymes as a consequence important nutrients are unavailable to the animal. But supplementation of enzymes to farm animals has shown to increase the digestibility of poorly digested diets to a much greater extent. By targeting specific anti-nutrients in certain feed ingredients, feed enzymes allow especially pig...
متن کاملImproving Forage Quality and Animal Performance with Fibrolytic Enzymes
Enzymes have been used for decades to improve the utilization of swine and poultry diets. For instance phytase, amylase, ß-glucanase and xylanase are added to the cereal-based diets of such monogastrics to increase the utilization of dietary phosphorous, starch, ß-glucans and arabinoxylans respectively. For many years, researchers were discouraged from using enzymes to enhance the utilization o...
متن کاملEffect of long-term onion (Allium cepa) feeding on antioxidant enzymes in goat erythrocyte
The effect of long-term onion consumption on red blood cell antioxidant enzymes [glucose-6-phosphate dehydrogenase (G6PD), superoxide dismutase (SOD) and glutathione peroxidase (GPx)], were measured. The relationship of these enzymes with PCV and hemoglobin (Hb) concentrations was also determined. Twelve adult female goats were used for the experiment and randomly assigned to three groups. Anim...
