one of the main factors affecting on the technical and economic performance of farms and livestock is the ability or capacity management. main goal of farm management is achieving specific performance, profitability and productivity; there for measurement management and performance in livestock farms are necessary. considering the necessity of increasing production and quality in the dairy indu...

documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. for this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. in t...

This study was conducted to investigate the scenario of buffalo production and reproduction under different farming systems at Subarno Char, in the coastal area of Bangladesh. A total of 14 farms were randomly selected and studied for various traits live weight (LW); daily milk yield (DMY); lactation length (LL); lactation production (LP); calving interval (CI); gestation length (GL); post part...

Introduction Improving milk productivity is essential for ensuring sustainable food production. However, the increasing difficulty of supervision and management, which associated with farm size, one major factors causing inverse relationship between size productivity. Digital technology, has grown in popularity recent years, can effectively substitute manual labor significantly improve farmers'...

In Serbia, carrots are produced on various land areas within agricultural companies and family farms. This study includes detailed analytical calculations of the realized value production, cost calculation, financial results carrot production three farms different sizes, as well comparison obtained results. The calculation presented in is based actual costs made during technological process fro...

this study investigates issues on efficiency and elasticity of broiler production in peninsular malaysia. data from 296 broiler farms were subjected to sfa, dea and bootstrap methods for technical efficiency; translog and tobit regression analyses to estimate elasticity of production and determinants of efficiency respectively in broiler production. we found that farmers produce mean efficiency...

From a total of 656 broiler farms with the permission of exploitation in Guilan province, data was gathered from 20% of active farms including 85 units (Capacity of over 1663000 portions of broiler chickens) to evaluate the management of nutrition and nourish using questionnaire. The questionnaires were completed by the interview method. The methods of making feed, feed formulation, the shape o...

We used variation in algal d13C between river habitats to study the spatial scale of energy flow through river food webs. We found a strong negative relationship between herbivore d13C (which reflects algal d13C) and water velocity in three productive Northern California rivers but not in unproductive streams. The contrast among habitats suggests that water velocity affects algal d13C most stro...
