Alpharma Beef Cattle Nutrition symposium: alternative energy sources for beef cattle finishing diets.
The Alpharma Beef Cattle Nutrition symposium was held at the joint annual meeting of the American Society of Animal Science, the American Dairy Science Association, and the Canadian Society of Animal Science in Montreal, Quebec, Canada, July 12 to 16, 2009. The symposium was organized to discuss the increased incorporation, challenges, and management options when alternative energy sources are ...
متن کاملEnergy Requirements of Zebu Beef Cattle
Projections for beef cattle production in Brazil for the next 10 years forecast an annual increase of about 3.5%. For the same period, a 2.22% growth in the domestic intake of beef cattle and an increase of 3.07% a year in exportation is estimated. This annual increase in exportation could reach 3.4 million tons by 2019, establishing Brazil as the main beef exporting country (MAPA/AGE, 2009). T...
متن کاملPreliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement
The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
متن کاملMineral Supplements for Beef Cattle
elements for normal bodily maintenance, growth, and reproduction. Minerals that are required in relatively large amounts are called major or macro elements. Those needed in small amounts are classified as micro, minor, or trace minerals. These terms, however, have no relationship to the metabolic importance of a mineral in the diet. A trace mineral can be as essential to the health and performa...
متن کاملAlternative Feeds for Beef Cattle
As a beef cattle nutritionist, two things have been drilled into to me from early on: 1) the cheapest way to feed the cow is to let her “harvest” her own feed by grazing, and 2) corn is the cheapest source of energy for fed cattle. However, fluctuations in corn and land prices in more recent years have raised questions regarding the truth in these old adages. The objectives of these proceeding ...
