Profitability and Profit Efficiency of Catfish Fingerlings Production in Edo South, Nigeria
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy, 2021-12-23) Joseph Ahmadu, Joseph; Odum, Emmanuel Egbodo Boheje; Osariemen, Faith Omoyemwen; Department of Agricultural Economics and Extension Services, Faculty of Agriculture, University of Benin, Benin City, Nigeria; El-Bohej Agro-Network and Consultancy Services, Edo State, Nigeria
This study used descriptive statistics, budgetary analysis, and stochastic profit function to analyze data collected from 120 catfish fingerlings producers in Edo State, Nigeria to examine the profitability and profit efficiency of their production. Results from the study show that catfish fingerlings production is a male dominated activity with a modal age of 21-40 years and 53.3% engaged full time as fingerlings producers. Clarias gariepinus was the dominant species used for fingerlings production. Producers earn a revenue of NGN 2,885,443.2 and make NGN 2,084,004.24 as net profit per production cycle 120,000 implying that catfish fingerlings production is a profitable venture in the study area. Labor cost, depreciation, and cost of transportation affected the profits of fingerlings producers positively in that they led to an increase in their normalized profit. About 70% of the catfish fingerlings producers operated above the mean efficiency value implying that most of the farmers were relatively efficient in profit making. Inadequate water supply, cost of feed, high cost of transportation, and inadequate funds were the major constraints faced by the respondents in the study area. Pest and disease outbreaks were not serious constraints. The study therefore recommends that causes of inefficiencies should be considered and treated so as to enhance higher efficiencies by catfish fingerlings producers and to operate at the optimum profit frontier. It is also recommended that solutions should be proffered to constraints to catfish fingerlings production by concerned authorities to make the venture sustainable in meeting with demands all year round.
Liquidity and Profitability of Meat Processing Enterprises in Poland
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy, 2021-12-23) Szymańska, Elżbieta; Lukoszová, Xenie; Warsaw University of Life Sciences, Faculty of Economics, Warsaw, Poland; Technical University of Ostrava, Czech Republic
The research aimed to identify changes in the level of liquidity and profitability of meat industry enterprises and determine the relationship between liquidity and profitability in this industry. The authors made a hypothesis that there is a positive relationship between the liquidity and profitability of meat enterprises, which means that along with the increase in financial liquidity the profitability of enterprises increased. The research used information from meat processing and preservation companies, except poultry, employing more than nine persons. The analysis covered companies that were obliged to submit financial statements to the National Court Register. In 2007, there were 467 such enterprises in Poland and 316 in 2018. The descriptive statistics, Pearson correlation coefficient, and linear regression analysis were used in the data analysis. The analyses show that the number of meat businesses in Poland is decreasing as a result of their consolidation and winding-up due to the difficult financial situation. The average current liquidity ratio of the enterprises analyzed between 2007 and 2018 remained at a satisfactory level from 1.054 to 1.49. The research shows a significant correlation between current and quick liquidity ratios and returns on assets and equity. The highest level of correlation occurred between the quick liquidity ratio and the asset profitability ratio. The profitability of meat enterprises in the long term is associated with maintaining financial liquidity. In turn, maintaining the ability to meet current obligations requires a rational management of profit and working capital.
Processed Animal Protein as One of the Elements of the Policy for Reducing Gmos in the Feeding of Livestock
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy, 2021-12-23) Dzwonkowski, Wiesław; Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy
The aim of this article is to present various conditions and aspects of the use of processed animal protein (PAP) in the feeding of livestock in the perspective of lifting the 20-year ban on its use in feed and determining its role in the policy of reducing GMOs. The study analyzes the current legal status, as well as new conditions and requirements at each production stage, with the management of processed animal protein based on the relevant Polish and EU legal acts. It also determines the scale of production and directions of the current PAP management, as well as the price conditions of its potential use in feed production. In the analysis, in addition to the literature on the subject, the authors used mainly source data from the Chief Veterinary Inspectorate, Statistics Poland, and the Ministry of Finance. The analysis of organizational and production conditions led to the conclusion that the main problem may be to maintain the so-called species purity in the production of PAP and feed with its use, followed by cross-feeding (PAP from poultry in pig feed and PAP from pigs in poultry feed), and severe consequences in the event of detecting irregularities. Moreover, a limiting factor may be the high price in relation to other protein feeds and consumer expectations that the animal products offered for sale were produced without the use of animal feed. The role and importance of processed animal protein approved for feeding in the balance of high-protein feed raw materials is likely to be small, but every possibility of using domestic protein sources should be encouraged and exploited to reduce the use of imported GM feed and improve protein self-sufficiency. However, a larger scale of domestic use of this very valuable source of protein may require administrative action by introducing indicative targets for the substitution of imported GM feed with domestic protein sources.
Supply and Demand Situation and Prices on the Global and Polish Sugar Market
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy, 2021-12-23) Chmielewski, Łukasz; Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy
The aim of the paper is to present the global and Polish sugar balance and the price situation. Several issues have been given particular attention. Firstly, the relationship between the production of sugar and bioethanol in Brazil and world sugar prices. Secondly, the relationship between Brazilian sugar and bioethanol exports and world sugar prices. Thirdly, the relationship between sugar prices in Poland and the world ones when the market support mechanisms at the EU level are in force and after they expire. The study used data from Statistics Poland, USDA-FAS, FAOSTAT, OECD-FAO, to name a few, and was based on correlation and linear regression analysis, as well as the Herfindahl-Hirschman index. The data analysis showed a statistically significant correlation between the production and exports of sugar from Brazil, as well as between Brazilian exports and world sugar prices. The analysis also showed a greater correlation between food prices than sugar and oil price quotas. A much greater correlation was also observed between the selling and retail prices of sugar in Poland and the world sugar prices after the abolition of sugar production quotas and minimum prices for sugar beet in the EU, as compared to the period of application of the support mechanisms.
