Assessment of consumer awareness regarding the implementation of innovative food packaging
(Estonian University of Life Sciences, 2025) Gaworski, M.; Sołtys, P.
Food packaging fulfills many practical functions. They protect against harmful external factors and facilitate transport, distribution on the market, and storage of products in households. They also provide information on food products' type and composition, preparation method, and shelf life. The important role played by packaging contributes to their continuous improvement. An example of this improvement is the implementation of innovative solutions, including active and intelligent packaging. The question remains whether consumers know about these innovative facilities and whether they use them. In search of an answer to this question, a survey was conducted on 210 respondents in the Mazovian region (Poland). The survey aimed to assess consumer knowledge and awareness of active and intelligent food packaging. The study was conducted using the CAWI (Computer-Assisted Web Interview) method. As many as 79% of respondents did not know the term active packaging. It was similar in the case of intelligent packaging - 79% of respondents did not know this type of packaging. Respondents also showed a low level of knowledge regarding the different types of inserts in active packaging and examples of benefits offered by intelligent packaging. The survey results suggest the need to disseminate knowledge and benefits related to active and intelligent packaging.
Assessment of dairy cow herd indices associated with different milking systems
(2018) Gaworski, M.; Leola, Arvo; Kiiman, Heli; Sada, Oliver; Kic, P.; Priekulis, J.; Estonian University of Life Sciences. Institute of Technology
The objective of the research was to find whether any differences exist between cattle herds operated by certain milking installations. The cattle herds were studied not only by herd size but also by certain data, like annual milk yield, age and number of lactations. Data collected on dairy farms that operate pipeline milking systems, milking parlours and automatic milking systems were analysed. These farms are situated in three Baltic States. The investigated Estonian dairy farms indicated a decreased tendency in the prevalence of disease cases for udder diseases with an increase in cow herd size. An index of cow production potential was proposed to compare different (including number of lactations) group of cows in dairy farms.
Association between body condition and production parameters of dairy cows in the experiment with use of BCS camera
(2020) Chlebowski, J.; Gaworski, M.; Nowakowski, T.; Matusiak vel Matuszewski, B.
Dairy production effectiveness in the farm depends on many technical, technological and biological factors. State of the dairy cow condition constitutes one of the most important element in the assessment of dairy herd and production indices. Including access to modern technical solution to assess body condition of dairy cows, i.e. BCS camera, some results of observation in the herd with 362 cows were collected to find any relationship between BCS index and milk yield per cow including 5 lactation groups and cows differed in age as well as four seasons. Basing on data collected in the period of 11 months it was found that cows with the BCS index lower than 2.9 showed the highest daily milk production. Increase in BCS index was associated with decrease in amount of produced milk per day. The statistical analysis showed significant effect of lactation period, age of animals and season on BCS results in the considered dairy cow production cycle.
Attitudes of a group of young Polish consumers towards selected features of dairy products
(2021) Gaworski, M.; Borowski, P.F.; Zajkowska, M.
Consumer opinion surveys include key elements of improving the food market and assessing consumers’ approaches to current issues related to access to high-quality food. In the survey, which aimed to find out the opinions of young Polish consumers about dairy products, the focus was on issues related to the assessment of selected features of dairy products and their packaging, evaluation of regional products and innovations in dairy production. The methodology for assessing the significance of the features of dairy products and their packaging was based on the proposed feature significance index (FSI). In the carried out research, young respondents pointed to the importance of taste and quality of dairy products, and indicated the small role of packaging, determining the choice of products concerned. The ease of product identification based on packaging has gained the greatest importance among the assessed packaging features. Over two-thirds of respondents indicated that they did not pay attention to the biodegradability of dairy product packaging. When asked about regional dairy products, respondents paid most attention to their value resulting from natural methods of production without preservatives, and least to freshness. In the opinion of young consumers, access to regional products increases the certainty of using raw materials from a given region and facilitates the development of local agricultural business. A small percentage of young respondents showed knowledge of the idea of dairy production ‘from grass to glass’, which would indicate insufficient interest in innovative solutions in the dairy sector.
The effect of the calibration of the spiral feeder and the type of feed pellets on the precision of its dosing
(Estonian University of Life Sciences, 2024) Chlebowski, J.; Gaworski, M.; Nowakowski, T.
When feeding dairy cows, there is a need for precise dosing of concentrate feed. The quality of the feed dosing process is influenced by the physical properties of the feed material and the accuracy of the feeder calibration. The aim of the study was to investigate the influence of the accuracy of calibration of the spiral feeder and the type of granulated feed on the precision of dosing feed material at the feeding station. The study used a feeding station intended for feeding cattle, equipped with a spiral feeder with a feed rates of up to 1 kg min-1. Three types of feed material with different granule diameters were used for the tests. The characteristics of the feed pellets included their bulk density, diameter and length of the pellets. In the study, the accuracy of the feeder calibration was related to the number of feed mass measurements obtained in the calibration procedure. Options for three and six mass measurements were included. The tests were performed for two feed rates, i.e. 0.3 and 0.4 kg min-1. In order to determine the accuracy of feed dosing by the spiral feeder, the dosing accuracy index was calculated. The research results were subjected to statistical analysis. A statistically significant impact of calibration on the accuracy of feed dosing was found. In the study, increasing the diameter of the granules was accompanied by an increase in the accuracy of its dosing.
Milk yield of cows in some European countries and the implementation of automatic milking systems
(Estonian University of Life Sciences, 2023) Gaworski, M.
The research study addresses the problem of implementing progress in agricultural production. This problem was developed on the basis of equipping farms with automatic milking systems (AMS). Different forms of progress can be identified on a dairy farm, including technical progress represented by AMS and biological progress expressed by milk yield of cows. The purpose of this research study was to compare whether the milk yield of cows in certain European countries meets the requirements for utilizing the milking potential of automatic milking systems. The study used information on the suggested amount of milk that an one-stall milking robot should milk per year. The second group of data was the annual milk yield of cows in the European Union countries and Great Britain. In eight countries, the annual milk yield of cows was in the range of 8,601–10,600 kg. It was found that in 2020, in these eight countries of the European Union, the milk yield of cows was at a level that meets the performance requirements of one-stall milking robot.
Trend of cow herd size in Baltic states
(2021) Leola, Arvo; Priekulis, J.; Česna, J.; Gaworski, M.; Estonian University of Life Sciences. Institute of Technology
The article analyses trend of cow herd size from 2000 to 2019 in four Baltic states: Estonia, Latvia, Lithuania and Poland. It has been stated that during this period of time the average size of cow herds has increased 3–4 times, except in Estonia, where it has increased 8 times. Nevertheless, the number of cows in the herds is different in individual countries. In the herds with up to 5 cows in Estonia there are about 2% of cows, but in the other Baltic states it is 10–18% of the total number of cows. In turn, in the herds with 50 or more cows, what corresponds to implementation of modern milk production technologies and machinery, in Latvia and Lithuania there are about 50% of cows, in Poland 30%, but in Estonia 90% of the total number of cows in the country. It has influenced the specific labour intensity of the people working in milk production. In Estonia, this indicator in 2019 was about 100 man-h per cow per year, but in the other Baltic states it was 300–350 man-h calculating per cow per year. Still, with robotization and automation of all basic work operations the specific labour intensity in milk production can be decreased to 30–50 man-h calculating per cow per year. Therefore, there are still great development possibilities in all Baltic countries.
Understanding animal welfare by students and graduates of different studies
(2020) Gaworski, M.; Turbakiewicz, S.
Animal welfare is one of the key elements of contemporary approach to animal production. Social consciousness of animal welfare concerns first of all persons responsible for practical implementation of individual solutions for animal welfare improvement. But what about other group of peoples and their relation to animal welfare? The aim of the paper was to analyze some aspects of animal welfare assessment including opinions given by young Polish citizens. The idea of the paper was to investigate, how kind of higher education represented by citizens show effect on understanding of animal welfare problems. The scope of the paper included survey, where 165 graduates of different studies (humanities, polytechnic, medical, economic, art and life sciences studies) had the possibility to present and assess their knowledge on animal welfare. In one of the questions, interpreting an ideal farm with animal production, most respondents, regardless of the field of study, pointed to the key role of maintaining the highest standards determining the welfare and comfort of livestock.
