Decomposing profit efficiency using a slack-based directional distance function
This paper develops a slack-based decomposition of profit efficiency based on a directional distance function.
متن کاملEffects of milk yield on biological efficiency and profit of beef production from birth to slaughter.
Effect of milk yield (MY) on biological efficiency and gross margin as an indicator of profit potential of beef production from birth to slaughter was determined. Data included 9 yr of spring-born single male calves. Biological efficiency was calculated as carcass weight/total feed energy intake, including nonlactating and lactating intakes of cow and creep and feedlot intakes of calf. Slaughte...
متن کاملMaximizing efficiency of rumen microbial protein production
Rumen microbes produce cellular protein inefficiently partly because they do not direct all ATP toward growth. They direct some ATP toward maintenance functions, as long-recognized, but they also direct ATP toward reserve carbohydrate synthesis and energy spilling (futile cycles that dissipate heat). Rumen microbes expend ATP by vacillating between (1) accumulation of reserve carbohydrate after...
متن کاملMaximizing profit using recommender systems
Traditional recommendation systems make recommendations based solely on the customer’s past purchases, product ratings and demographic data without considering the profitability the items being recommended. In this work we study the question of how a vendor can directly incorporate the profitability of items into its recommender so as to maximize its expected profit while still providing accura...
متن کاملTriennial Lactation Symposium: Opportunities for improving milk production efficiency in dairy cattle.
Increasing feed costs and the desire to improve environmental stewardship have stimulated renewed interest in improving feed efficiency of livestock, including that of US dairy herds. For instance, USDA cost projections for corn and soybean meal suggest a 20% increase over 2010 pricing for a 16% protein mixed dairy cow ration in 2011, which may lead to a reduction in cow numbers to maintain pro...
