Opis:
Small ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.

Opis:
Egyptian waste cooking oils have special specifications because it expose to high temperatures during use for long hours. In the present experimental study, the performance and emissions of a four strokes, single cylinder, aircooled diesel engine fuelled with two different biodiesel from Egyptian used cooking oil (palm and sunflower) are evaluated at different speeds. The measured performance parameters include torque, fuel consumption and exhaust gas temperature. Brake power, brake specific fuel consumption and brake thermal efficiency was calculated using the measured test data The emission parameters include carbon monoxide, particulate matter and the oxides of nitrogen. The tests have been carried out with different blends of B5 to B100 of biodiesel with diesel fuel. The results showed that the cetane number of sunflower biodiesel has dropped significantly as a result of high temperatures and negatively affected the performance and emissions of the diesel engine also the engine performance with the palm biodiesel blend B5 is closed to diesel fuel also, for B5 CO emission decreased from 53 to 70% while NOx emission decreased from 13 to 80% compared to diesel fuel.
