The objective of this study was to compare the growth performance of two Nguni ecotypes and its crosses (Nguni x Landim) raised under the same feedlot conditions at the Posto Fomento do Impaputo, in southern Mozambique. Live weight feedlot data, from entry to marketing, were collected every fortnight between 1999 and 2009 from 453 oxen of the Nguni and Landim male ecotypes, as well as the crosses. Year-season of birth had significant effects on live weight at entry in the feedlot and at marketing age. Overall means for average age at entry in the feedlot was 31.8 ± 4 months, with the Landim being younger than the Cross (p=0.07). The average live weight at entry in the feedlot was 390 ± 42.5 kg, with no differences between ecotypes (p>0.05). Males born in dry year-seasons were heavier than males born in wet years-seasons (p<0.0001 to p<0.05).The average age at marketing of the Nguni ecotypes was 34.4 ± 5.08 months, with the Landim being younger (p<0.05) than the Cross. The average live weight at marketing was 446 ± 42.2 kg. The average live weights at entry and at marketing were higher in dry years-seasons than in wet years-seasons. There were no differences between ecotypes for average daily gain (0.89 ± 0.79 kg) in this study. Growth rates for the feedlot in the Nguni cattle obtained in this study were substantially lower than that obtained for the Ngunis in South Africa albeit they entered the feedlot at a much older age. This study demonstrates that in Mozambique feedlot industry is still underdeveloped with main constraints on feed resources, especially concentrates.

he survey was carried out in Horro district of Horro Guduru zone, west part of Ethiopia. The objectives of the survey were: to describe cattle production system, trait preferences, breeding practices, and constraints in utilization of the breed and to use the information generated as baseline data to design breeding strategy of the breed. Data were collected through in-depth interviews, group discussions and secondary data collections from different sources. Statistical Package for Social Science was employed to analyze data. Horro cattle are kept in a mixed crop-livestock production system and are the dominant livestock species in the area. Cattle have multi-functional roles in the production systems. Among reason of keeping cattle, draught power was ranked first followed by milk production. Farmers prefer composite traits from their male and female cattle. Draught power performance, body size, hump size, adaptability and coat color were among the higher ranked preferred traits for male cattle in that order. Preferred traits for female cattle include milk yield, fat yield, calving interval, adaptability and coat color.

In order to describe the ways of handling, processing and marketing of milk in urban and peri-urban production systems of the North western Ethiopian highlands, 256 and 54 dairy farms were selected for survey and monitoring data collection, respectively. Due to poor market access and high transaction costs and the perishable nature of raw milk, the amount of sold milk (products) and prices were significantly lower for peri-urban producers. Prices were also low during fasting periods and during the wet season; when milk production was reactively high. Traditional ways of milk processing at household level include practices which may contain risks for product quality affecting consumers’ health. Providing basic handling and health education for producers therefore is likely to result in improved milk (product) quality on the markets. Direct delivery to the nearby consumers was the largest primary milk outlet for producers of both systems, while retailers and milk cooperatives were the second most common outlets for the urban and the peri-urban system, respectively. Therefore, to enhance dairy production and marketing, milk co-operatives that could be able to market larger volumes and sufficiently reduce transaction costs should be supported by governmental and non-governmental organisations through providing technical and infrastructural support.

Nigerian indigenous chicken (NIC) from three agro-ecological zones (Rain Forest, RF; Derived Savanna, DS; and Guinea Savanna, GS) were evaluated for age at first egg, egg production and egg weight, percent hen-day egg production and percent laying mortality. Data for this work were collected over a period of 72 weeks. A total of 579 eggs from DS and RF zones and 505 growers from DS, GS and RF were evaluated. Data were compiled by Dbase IV and analysed using the General Linear Model (GLM) procedure of Statistical Analysis System (SAS). Agro-ecological zones, age and sex were the fixed effects in the model. Means for each variable effect were compared using the Least-Square Analysis of Variance and Duncan option of SAS. For all the traits evaluated, there was no significant difference between the chickens from the three ecological zones. Hence, the Nigerian indigenous chickens from these zones cannot be said to belong to different genetic groups.

The objectives of this study were to (1) describe the economic agents of the chain and their commercial and legal relationships; (2) identify the articulations between links, technological levels, indicators of efficiency, installed capacity (scale), and degrees of occupation; (3) characterize and estimate the costing and pricing structures, and the generation of value in different links of the chain; (4) identify those critical costs that can be modified through technological interventions, policy, or other activity; (5) determine the biological and economic risk factors throughout the chain; and (6) develop a methodology to identify and estimate the costs and benefits in each segment and evaluate the generation of value throughout the beef chain. Data at the farm level was obtained from a national livestock survey (CORFOGA 2005b), which provided data on production systems, inventories, productivity, culling, and labor. In addition, surveys were carried out in different segments: (1) auction houses, (2) slaughterhouses, (3) butcher shops, and (4) supermarkets. The aim of these surveys was to describe behavior, determine risks and costs, and identify problems. The weak dynamics of livestock production in Costa Rica are reflected in unsatisfactory productivity indicators. The annual gross income was estimated as US$44/ha for cow-calf operations, $126/ha for dual purpose (including income from milk sales), and $135/ha for fattening activities. Such income rates are considered extremely low, if one uses as reference the commercial value of land allocated to livestock production (ranging between $1000 and $2000/ha). The aforementioned biological inefficiencies, combined with high land costs, impede the recovery of opportunity costs for the capital invested in land, thus making beef production uncompetitive. The cow-calf operation, with its low productivity, remunerates family labor with wages below the legal minimum. On the assumption that the only cash cost is that of labor, cow-calf farms pay family workers at a wage that is equivalent to 60% of the legal minimum. Auctions present relatively good profits per event. However, when these profits are analyzed on a calendar-day basis, they are unattractive because of the low use of installed capacity. One strategy that would usefully improve the efficiency of the auction system in Costa Rica is its integration to reduce the number of fixed operational costs or encourage sharing of these houses so that administrative and operational personnel are rotated among the several existing auctions, taking advantage of the fact that they differ in their days of operation. This scheme would help reduce fixed costs and the commission collected without affecting profits, thus improving efficiency in this link of the chain. However, this option is not easy to implement, as auctions are run by private operators, whose various interests do not always coincide. The industrial sector formed by rural and industrial slaughterhouses shows a low occupation of installed capacity, resulting in high operational costs and low labor efficiency. The total operational costs of slaughtering and dressing are estimated as being between US$32 and $66 per animal. If the estimated unit costs are compared with the rates charged per slaughtered animal (between $15 and $23), then we have to conclude that rural slaughterhouses work at a loss and that industrial slaughterhouses cover their operational costs with processing services and the very small profit margins from sales of byproducts. The best performance in terms of efficiency and profitability is found in the retail sector of butchers and supermarkets. The rate of profits, expressed as the fraction of the final price paid by the consumer that remains in the butcher’s hands as remuneration of his work, ranges widely between 3% and 40%, with an average of 32%. If these profit rates are compared with those of other retail businesses, which are about 8%, then this type of activity presents excellent profit margins with relatively low risk. If, in addition, we take into account that this sector also offers the consumer a broad range of meat cuts from other animals such as pork and chicken, and processed meats, then profit margins are still higher. The value generated throughout the chain, as a percentage of the final value of the young steer at retail price according to activity, is distributed as follows: fattener (34%), retailer (33%), breeder (19%), slaughterhouse (7%), transporter (6%), and auction house (1%). As observed, the distribution of value throughout the beef chain is totally inequitable and incongruent with the level of individual risk confronted by the actors who form it. The inequity observed in the distribution of added value reflects a clear dominant position in the market of some actors of the chain, which enables them to capture a very high fraction of the profits. The value generated in the chain, adjusted for operational time in each link, ranges between US$0.28/animal per day for the breeder and $45.85/animal per day for the butcher. Thus, the highest proportion of the total added value concentrates on the final link of the chain. The butcher or supermarket obtains, on the basis of one animal in the same unit of time, 164 times more value that the breeder located in the first link of the chain. The latter has to confront biological and economic risks not covered by insurance policies, whereas retailers may mitigate risks through insurance policies for their raw materials, equipment, and infrastructure. The competitiveness of the beef chain is the aggregate of the efficiency and productivity of all the links that form it. In a situation where, in the final segment, the demand for beef is low and weakly dynamic, then economic signs of modernization and the technological change it promotes, are not being generated in other components of the chain, particularly in the first link of production. This, in turn, results in a vicious cycle, generating low productivity and lack of competitiveness. To promote technological change, efficiency, and competitiveness in the value chain for beef in Costa Rica, we propose the following six recommendations: 1. That successful experiences of other chains such as that of poultry be analyzed and learned from to identify strategies that would increase the efficiency of the beef chain as a whole. 2. That strategies for promoting the milk production of breeding cows be developed to increase family income, as remuneration of labor is currently below the minimum wage. This option would be viable only in localities where a milk market exists. That livestock producer funds [a livestock producer fund consists of granting livestock in company to produce meat, provided that the producer concerned has adequate pastures for this purpose on his farm] be created as mechanisms to develop social capital, reduce transaction costs, and help improve the chain’s productivity and profitability. These organizations would bring together the different classes of the chain and favor synergies in the interaction of public and private actors. 3. That incentives be created to promote the large-scale adoption of already available improved forage species, as most of the problem of low livestock productivity originates in poor and deficient feed. This strategy would emphasize feeding during dry seasons, thereby minimizing seasonal weight losses in the national herd and improving the profitability of farms. 4. That a carcass classification system be established, based on quality and price that would permit differentiating supplies for different segments of the market. 5. That consumer education be promoted on the health benefits of beef, forms of preparation, and differentiating between cuts, uses, and qualities of beef products.

The non-spore forming gram-positive bacterium Listeria monocytogenes is a food pathogen bacterium and the causative agent of listeriosis. The aim of study was to determine the survival limits of L. monocytogenes inoculated in manufactured cold smoked sausages depending on water activity (aw) and pH values. Enumeration of L. monocytogenes colony forming units per gram (cfu gE-1) was done according to ISO standards. The decreasing water activity conditioned by moisture (weight) loss during ripening and pH decrease ensured negative exponential growth rate of inoculated L. monocytogenes lg cfu gE-1 - 0.44 each day. A significant Pearson's correlation (p is less than 0.01) was established between decreased values of L. monocytogenes count, aw (0.99), pH (0.92), moisture % (0.96), and weight loss (0.93) in sausages during ripening. The experiments were done at the Faculty of Veterinary medicine of the Latvia University of Agriculture and in a sausage manufacturer's laboratory.

Innovation capacity has to be viewed as a consequence of properly operating innovation system. Well established and functioning innovation system is a result of enhanced by government innovation policy. In comparison with other European Union (EU 27) countries, innovation capacity indicators in Latvia remain low and considerably underperform, reflected in the 'European Innovation Scoreboard 2008', where Latvia took the 30th place among 32 countries. Problems and solutions are illustrated to represent innovation capacity in Latvia. This article consists of the following parts: first - theoretical aspects are selected to describe the essential definition of the analyzed subject. In the second part, experience from abroad is described, at the end – Latvian innovation policy and situation is analyzed and suggestions for further needs are formulated. The main results of analysis show that only a few elements of innovation capacity building are functioning at Latvian enterprises, whose aim is to build a base for the innovation capacity of the country.

Regional development should not be a unified process even for a small country such as Latvia. There is a stereotype that people living in big cities and rural areas differ in their values and behaviour. This study compares the human values of Riga, the Riga district urban area and different rural regions in Latvia. During the last three years - 2007, 2008 and 2009 the survey of 1450 inhabitants showed no substantial difference in peoples' social values; comparing rural and urban locations. Rather, a noticeable difference in human values between people living in different regions of Latvia was observed. It was also observed that the set of values expands in different directions over time, forcing a future increase in fragmentation and segmentation of the population in the country.

Despite Latvia being a small country, it bears marked territorial or regional differences both between smaller administrative territorial units (local municipalities, republican cities and districts) and between larger territories – regions. From 2004 till 2008 Riga received 50% of all European Union (EU) funding. Latgale received the smallest part of financing (10%); the rest of the funding was split almost equally among Zemgale (12%), Vidzeme (12%) and Kurzeme (13%). As specific tasks for the development of specific territories or a balanced distribution of financing were not put forward for the strategy of acquiring funds, the fund investment has been attracted only to those territories where the yield could be the biggest or where the absorption capacity was the highest.

The study was accomplished in 2010. The applied research methods are based on the analysis of the studies by other authors, industry experts, statistic data and the (unpublished) information provided by the Latvian district heating merchant “xxx”. Spearman’s rank correlation coefficient was used for evaluating data regularity. In 2020 the energy produced from renewable sources (Directive 2009/28/EC) in total energy consumption in Latvia has to reach 40%. Such an objective can be achieved by promoting the use of biomass at cogeneration (CHP) plants, the potential of which is the district heat supply system. Wood as an energy resource in its structure accounts for only 25-30%; therefore, the primary condition is the introduction of modern technology which would provide the possibility to diversify energy resources. The calculations confirm that the realised amount of thermal energy indirectly affects profit; directly it is affected by the rate of thermal energy, so the structure of use of energy in heat supply enterprises is associated with lowering the cost of (restrictive) factors - the energy cost, specific production technologies, energy efficiency. Currently, the primary condition of heating companies is to find such energy resource(s) to ensure the approved schedule of temperature and thermal load. The next determining factor is the energy price. In assessing the factors that will affect energy usage in the future, the main strategic principle of energy consumption will be linked to limiting the growth or even reducing heat tariff, by realising optimal efficiency and minimal environmental pollution during energy transmission.
