Rumen Manipulation to Improve Animal Productivity
Anaerobic rumen microorganisms mainly bacteria, protozoa and fungi degrade ligno-cellulosic feeds consumed by the ruminants. The ruminants in developing countries are predominantly maintained on low grade roughage and grazing on degraded range land resulting in their poor nutrient utilization and productivity. Hence, manipulation of rumen fermentation was tried during last two decades to optimi...
متن کاملManipulation of the Rumen Microbial Environment to Improve Performance of Beef Cattle
It is well known that rumen fermentation processes play a key role in ruminant nutrition, as it is this distinctive symbiotic feature between the host and the rumen microflora that lends the ruminant animal several advantages in digestive and metabolic processes over non-ruminants. The extent of complexity of interactions between diverse groups of microorganisms which inhabit the rumen is such ...
متن کاملIntelligent scheduling for emergency room(ER) personnel to improve productivity
Improving productivity in emergency services and managing limited resources of emergency room(ER) are key challenges for health managers of oil industry. One critical and costly resource is ER personnel and its lack can lead to long queue of patients. Thus appropriate scheduling for nurses and physicians can help ER managers to get maximum benefit of their current human resource and reduce th...
متن کاملRumen Protozoa - Potential for Manipulation
The manipulation of rumen function through the removal of the ciliate protozoa has not resulted in consistent changes in ruminant production. Current research findings are discussed with particular emphasis given to the role of protozoa in fibre digestion in the rumen and the availability of protein for intestinal digestion. Dietary conditions under which positive responses to defaunation can b...
متن کاملNew products for rumen manipulation.
In terms of improving animal productivity and profitability, the use of monensin and related ionophoric antibiotic growth promoters has unarguably been one of the major successes of rumen microbiology in contributing to ruminant nutrition (Russell & Strobel, 1989). Addition of ionophoric antibiotics to ruminant diets has been associated with beneficial changes in the ratio of volatile fatty aci...
