Adjustment and Differences in Farm Performance - a Farm Management Perspective from the Netherlands

Poppe, Krijn J.; van Meijl, Hans.

There are differences in performance between farmers. In the Netherlands this has been a major topic of research for at least 30 years. Research has shown that the managerial capacities of farmers play a major role in differences in economic and environmental performance. Management can be measured and the optimal level is not the maximum level. Farmers differ in their objectives, competences and local external situation and therefore their strategies. These strategies can be identified. In recent years strategic management has become more important and this can be supported with consultancy. Farmers also differ in their adoption and innovation behaviour. These micro economic results, that correlate with large differences in income and high prices of fixed...

Agro-food chain: an innovative paradigm for food and rural policy analysis and agro-food chain segments’ systemic performance at regional level

Samoggia, Antonella; Maccani, Paola; Marchi, Alan.

The food chain concept is an increasingly common theoretical instrument for food and rural development policy and many countries adopt the so-called “new rural paradigm”, so to integrate different sectoral policies. This paper aims at adopting the food chain paradigm in order to analyse the regional agro-food system and to sustain the design and delivery of consistent inter-sectoral policies. It adopts the netchain concept (Lazzarini et al, 2001) and the theory of governance patterns in global value chains (Gereffi et al, 2005). Results show this innovative approach contributes to better understand and stimulate economic performance of the whole agro-food network.

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS

Alternativas de manejo do capim tifton 85 sob pastejo por cabras leiteiras em lotação rotativa.

Rosario, Joe A..

Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

The need for suitable diets in chickens, considering the ideal protein concept associated with phytase, is important in order to improve the productivity of birds. The aim of this study was to assess the need for the correction of amino acid levels in the diets of broilers, by using different combinations of crude protein (CP) supplemented with phytase. For performance, eight days old Cobb 875 broiler chicks, with initial body weights of 155 ± 1.4g were used. The birds were distributed in a completely randomised design with seven treatments (nutritional plans) and five replicates of 25 birds. For the metabolism trial, 300 birds were selected which were also distributed using the same design, but with five, four and three birds per experimental stage: 8-21...

An experiment was carried out to evaluate the effects of Echinacea purpurea (EP) extract at 5 levels (0, 0.25, 0.5, 1 or 2 mL L-1 of drinking water) on performance, internal organs and gut microflora of Japanese quail (Coturnix coturnix Japonica). The results showed that EP extract decreased feed intake and body weight gain of quails. The feed conversion ratio of quails fed with EP extract at the level of 0.5 ml L-1 drinking water was significantly decreased compared to the control group. Adding EP extract at the levels of 0.25, 0.5 or 1 mL L-1 drinking water decreased carcass yield of the birds (p < 0.05). The relative weight of internal organs of the birds fed different levels of EP extract was not significantly different. Birds consumed EP extract at...
