The Cost

Recent studies at this centre (Flanagan 2003, Keady et al. 2006) have shown that grazing swards in the winter (extended grazing), either in mid, late or throughout pregnancy, provides a low-cost system for wintering ewes. With decoupling of subsidy from production post Mid Term Review of the Common Agricultural Policy it is essential to improve efficiency and reduce costs of production. One of the major costs in sheep production is the cost of rearing replacements. The aim of the present study was to evaluate the effect of herbage allowance and concentrate supplementation on animal performance during extended grazing and on compensatory growth during the subsequent grazing season. Furthermore the potential herbage allowance sparing effect of concentrate supplementation was also determined.

It is essential to improve efficiency and reduce costs of production with decoupling of subsidy from production post Mid Term Review of the Common Agricultural Policy. Recent studies at this centre (Flanagan 2003, Keady et al., 2006) have shown that extended grazing (grazing during winter), either during mid, late or throughout pregnancy, provides a low cost system of wintering ewes. The aims of this study were to evaluate the effects of herbage allowance and frequency of allocation, and potential interactions during mid gestation on ewe performance, and lamb birth weight and subsequent performance. Furthermore a direct comparison of herbage allowance and grass silages of differing feed value was also undertaken.

Autumn And Winter

Progress in the development of autumn and winter lambing systems in Northland is described. Both involve split flock lambing in which 30 or 15% of ewes lamb in autumn or winter respectivelv, the remainder in spring. Using progesterone priming, a high ram to ewe ratio (10%) and ram management, 80.90% of ewes joined lamb over 2 cycles. Winter lambing using cull ewes is simple and does not require a breeding programme. Ewes and their lambs can be sent to the meat works from September. For low cost lamb production with present breeds, autumn lambing requires a breeding programme to develop spring mating ability. Heavyweight(18kg)carcasses can be produced early in the killing season. Autumn born replacement ewe lambs consistently averaged 40kg before their first summer. Both systems offer more flexibility in sheep production on farms and in processing and marketing.

The Cost

For a determination of the system’s efficiency and decrease the cost, a low cost system for measuring solar irradiance is designed. By analyzing the influence of solar irradiance and temperature to solar cell, we have found that in case of different temperatures the variation of short-circuit current (Isc) in function of solar irradiation incident (E) is always linear. Then the read-out circuitry is designed to measure and convert the signal which is detected by the photoelectric cell and thermocouples. At last, the software is developed to compensate the temperature and make sure the device work normally. The results of detecting the system show that it’s effective and reliable.

Post Mid Term Review of the Common Agricultural Policy, beef production must survive in a subsidy-free, market led environment. It is essential that producers increase final carcass value by achieving cost effective performance from birth to slaughter. The aim of the present study was to evaluate the effects of plane of nutrition during the growing and finishing indoor feeding periods, and stocking rate and concentrate supplementation at pasture on the performance of steers and heifers from weaning to finishing.

The purpose of the article is an attempt to determine, in the 2019 perspective, the economic situation of farms specialising in cereals, oilseeds and protein crops, with the economic size of 4–25 (very small), 25–50 (medium-small), 50–100 (medium-large) and 100 thousand EUR and more (large), operating on lower soils with the soil classification index (SCI) of up to 0.7, with an emphasis on changes in the Common Agricultural Policy (CAP) 2014–2020 as compared with the CAP 2007–2013. This was made using a model-based method (linear-dynamic programming method). These models adopted the maximisation of agricultural farm income as a criterion for optimisation. It was determined that the growth in income of these farms will be limited in case unfavourable pricing conditions on the market of biotechnological products and production measures last until 2019. This will mean that, in 2019, very small cereal farms will have no funds to pay the cost of farmer and his family’s labour at the parity level and the cost of development, while medium-small cereal farms will have no funds for development. Only medium-large and large cereal farms will retain the possibility to pay the cost of farmer and his family’s labour at the parity level and the cost of further development.

Abstract Total body positron emission tomography (PET) systems are being developed by different groups worldwide. These systems have potential to change the number of applications in which molecular imaging is used. The change from a short axial field of view (FOV) to a longer one is however associated with a linear increase in the cost of these systems. This may limit their application to a small number of centers (capable of obtaining sufficient research funding). Therefore it remains interesting to see if lower cost systems can be developed and bring total body PET to the clinic for an acceptable budget. The wider availability of this low cost system can also enable more researchers to further optimize and explore the full potential of total body PET.

Community Decision

During the 1970s the European Community's Common Agricultural Policy (CAP), acclaimed only a decade earlier as prominent evidence of successful integration of member states, manifest major defects. Farm prices to the consumers increased continually, large surpluses of certain farm commodities accumulated, the cost of operating the CAP rose tremendously, and recurring changes of member state currencies made a shambles of the common price and market concept. Several general and specific causes of those problems can be identified. Strongly influenced by powerful national farm lobbies, the member governments have imposed their own interests, often at variance with the “common” interest, upon the Community decision-making framework. The large number of national officials participating in the CAP implementation process has tended to strengthen trends toward policy outcomes undesirable from the Community perspective. More specifically, the main cause for disrupting agricultural price and market unity has been the system of “green” currency rates and the monetary compensatory amounts (MCAs) which have provided the member governments with opportunities to reconstitute national control over farm prices. Fear of domestic political repercussions has restricted the creation of vigorous policies to counter surpluses, and structural improvement of farms, badly needed in some regions of the Community, has been slow.
