The technique of the processor farm has become very widely used for paral-lelising applications, often being mentioned without reference to any source. The goal of this work has been to put together a complete and rigorous understanding of what the technique can be used for and what is needed in order to arrive at an eeciently farmed application. This paper consists of these two parts. We have ...

This contribution is based on the personal experiences of the author as a typical crop farmer in Holland in 1925-1991, as a researcher at the Dutch Institute of Agricultural Engineering (19541964), and as the Director of that Institute in the period 1964-1983. In essence, the 20th century developments in mechanized agriculture are considered from a historical perspective. The future of farm mec...

We studied genotype by environment interaction (G × E) for body weight (BW) of Atlantic cod (Gadus morhua L.) from the National cod breeding program in Norway. Records of 13,811 fish in a nucleus farm (NUC) and two test farms (PENorth, PESouth) in year-class (YC) 2007, and for 9149 fish in NUC and one test farm in YC 2010 were available. Heterogeneity of variances and heritabilities ( ) were es...

The aim of this study was to develop a new genetic evaluation model to estimate the genetic merit of boars for growth based on 1) performance of their crossbred progeny fattened in the test station and 2) their own performance or those of relatives from the on-farm testing system. The model was a bivariate random regression animal model with linear splines and was applied to Piétrain boars from...

Popular government presupposes the existence of liberty, equality, and justice as its fundamental principles. Theoretically these principles prevail in Michigan. Practically they do not. How is it as to political rights ? One-half of the people, though subject to the laws, have no voice in making those laws. Their right to vote and the right of the people to cast their votes for them is denied....

BACKGROUND Health, productivity and antimicrobial use in the production of pigs are expected to be interrelated to some extent. Previous studies on register-based data have investigated these correlations with a subsequent large variation residing at the farm level. In order to study such farm factors in more detail we designed an elaborate interview-guide. By in-depth interviews of farmers wit...

Of all markets, the land market has been thought independent variables.2 Respondents were asked to to be one of the most difficult to explain. Techniques report on one randomly selected 1970 transaction for predicting land prices leave much to be desired. with which they were familiar. Of the 155 Nevertheless, the importance of this market continues questionnaires sent, 63 were returned with es...

Many farmers in the developing world have limited access to agricultural technologies and markets. Mobile phone-enabled services that offer price information and market linkages could contribute towards bridging this gap by reducing uncertainty about expected profits, information asymmetries and market inefficiencies. This article uses the example of the price information and marketing service ...
