No full textU radu su prikazani mogući alternativni izvori proteina i masti u hranidbi peradi. Poseban fokus stavljen je na uporabu brašna ili ulja crne vojničke muhe, brašna cvrčaka i skakavaca, algi i vodene leće u dizajniranju krmnih smjesa za perad. Istraživači su eksperimentima dokazali pozitivan učinak uporabe alternativnih izvora proteina i masti u hranidbi peradi na zdravlje, performanse brojlera i kokoši te kvalitetu mesa i jaja. Navedeni alternativni izvori proteina i masti u krmnim smjesama za perad mogu uspješno zamijeniti konvencionalne izvore proteina poput ribljeg brašna i sojine sačme. Zaključno gledajući, uvođenjem alternativnih izvora proteina i masti u hranidbu peradi može se značajno unaprijediti održivost i ekonomičnost proizvodnje peradi.The paper presents possible alternative sources of protein and fat in poultry nutrition. A special focus is placed on the use of black soldier fly flour or oil, cricket and grasshopper flour, algae and duckweed in the design of feed mixtures for poultry. Through experiments, researchers have proven the positive effect of using alternative sources of protein and fat in poultry nutrition on the health, performance of broilers and hens, and the quality of meat and eggs. The mentioned alternative sources of protein and fat in feed mixtures for poultry can successfully replace conventional sources of protein such as fish meal and soybean meal. In conclusion, by introducing alternative sources of protein and fat in poultry feeding, the sustainability and economy of poultry production can be signifi-cantly improved
Heavy metal contaminator of wild ducks diffrnt tissues caught by using steel shot
No full textCilj istraživanja bio je obraditi koncentraciju teških metala u tijelu divlje patke (Anas platyrynchos platyrynchos) u oba spola i utvrditi postoji li prekomjerna koncentracija ikojeg teškog metala. Tijekom ožujka 2023. godine skupljeno je 11 uzoraka sa Pisarovinskih ribnjaka. Neposredno nakon odstrjela uzorci su u 2 navrata odneseni u Veterinarski institut u Zagrebu gdje su uzeta tkiva za analizu. U svrhu analize uzeto je 6 različitih tkiva. Uzorci su se zatim obradili nakon čega smo dobili parametre 14 teških metala. Od svih parametara dobivenih u analizi, obrađeno je odabranih 5, a to su redom željezo (Fe), cink (Zn), bakar (Cu), kadmij (Cd) i olovo (Pb). Obradom podataka zaključeno je da se u tijelima pataka nalazi povišena koncentracija teških metala što ukazuje na onečišćenje okoliša u kojem obitavaju.The aim of the research was to analyze the concentration of heavy metals in the body of the wild duck (Anas platyrhynchos) in both sexes and to determine if there is an excessive concentration of any heavy metal. During March 2023, 11 samples were collected from the Pisarovina fish ponds. Immediately after the culling, the samples were taken twice to the Veterinary Institute in Zagreb, where tissues were collected for analysis. For the purpose of the analysis, six different tissues were taken, with the note that an additional already-formed egg was taken from one female specimen. The samples were then processed, after which we obtained parameters for 14 heavy metals. Out of all the parameters obtained in the analysis, five were selected for processing, namely iron (Fe), zinc (Zn), copper (Cu), cadmium (Cd), and lead (Pb). The data analysis concluded that there is an elevated concentration of heavy metals in the bodies of the ducks, indicating environmental pollution in their habitat
Pig fattening familiy farm Pilaš
No full textSvinjogojska proizvodnja kojom se već dugi niz godina bavi OPG Pilaš pokazala se vrlo uspješnom i profitabilnom. Ostvarivanjem prava na EU fondove, gospodarstvo je prešlo u višu razinu poslovanja i time će u narednim godinama konkurirati na lokanom tržištem. Planiranjem i dobrom brigom za sva grla na imanju, gospodarstvo pokušava svesti svoje troškove na što manji iznos, a svinje dovesti do što boljih proizvodnih rezultata i boljeg zdravstvenog stanja životinja. Definiran je cilj proizvodnje temeljem zahtjeva mesnih industrija i konzumenata, a koji se svodi isključivo na proizvodnju mesa određene kvalitete te polutrajnih i trajnih proizvoda od mesa. Ovakvi zahtjevi tržišta stoga zahtijevaju i iskorištavanje izrazito mesnatih pasmina svinja. Temeljem dosadašnjeg poslovanja, glavni plan OPG-a Pilaš je povećanje proizvodnje i razvijanje u korak s konkurentnim proizvođačima na tržištu.Pig production, which OPG Pilaš has been engaged in for many years, has proven to be very successful and profitable. By realizing the right to EU funds, the economy has moved to a higher level of business and will therefore compete on the local market in the coming years. By planning and taking good care of all the pigs on the farm, the farm tries to reduce its costs to the lowest possible amount, and bring the pigs to the best possible production results and a better health condition of the animals. The production goal is defined based on the requirements of the meat industry and consumers, which is limited exclusively to the production of meat of a certain quality and semi-permanent and permanent meat products. Such market demands therefore require the use of extremely meaty pig breeds. Based on the previous operations, the main plan of OPG Pilaš is to increase production and develop in step with competitive producers on the market

Agri-entrepreneurship development through the sharing economy
No full textAgrarno poduzetništvo obuhvaća aktivnosti vezane uz proizvodnju, preradu i distribuciju poljoprivrednih proizvoda, zahtijevajući inovativnost i prilagodbu promjenama tržišnih i ekoloških uvjeta. Suočava se s izazovima kao što su klimatske promjene i tržišne fluktuacije, ali također koristi napredne tehnologije za poboljšanje operacija. Povezivanje agrarnog poduzetništva s ekonomijom dijeljenja otvara nove mogućnosti za održivost, omogućujući ponovnu uporabu resursa i smanjenje otpada. Ekonomija dijeljenja nema jedinstvenu definiciju, no općenito se odnosi na ponovnu uporabu nedovoljno iskorištene imovine i resursa. Modeli ekonomije dijeljenja uključuju pristup resursima na zahtjev, automatizirana tržišta i usluge na zahtjev. U ruralnim područjima, ekonomija dijeljenja može uključivati dijeljenje kuća, zemljišta i alata, donoseći ekonomske, društvene i ekološke koristi. U zbrinjavanju otpada, razvijeni su društveni konstrukt povjerenja i zahvalnosti. Istraživanja pokazuju da ekonomija dijeljenja povećava produktivnost, smanjuje troškove i optimizira resurse, pružajući brojne prednosti u usporedbi s nedostacima, kako u turizmu, tako i u zbrinjavanju otpada. Cilj rada je istražiti razvojne mogućnosti agrarnog poduzetništva kroz primjenu ekonomije dijeljenja, s posebnim fokusom na ponovnu uporabu hrane.Agricultural entrepreneurship encompasses activities related to the production, processing, and distribution of agricultural products, requiring innovation and adaptation to changing market and environmental conditions. It faces challenges such as climate change and market fluctuations but also leverages advanced technologies to improve operations. Connecting agricultural entrepreneurship with the sharing economy opens new sustainability opportunities, enabling the reuse of resources and waste reduction. The sharing economy lacks a single definition but generally refers to the reuse of underutilized assets. Sharing economy models include on-demand resource access, automated marketplaces, and on-demand services and resources. In rural areas, the sharing economy can involve sharing houses, land, and tools, bringing economic, social, and environmental benefits. In waste management, trust and gratitude have emerged as social constructs. Research shows that the sharing economy increases productivity, reduces costs, and optimizes resources, offering numerous advantages compared to disadvantages, both in tourism and waste management. The aim of this paper is to explore the development opportunities of agricultural entrepreneurship through the application of the sharing economy, with a particular focus on food reuse
Agricultural land management in the Republic of Croatia
No full textDobro upravljanje poljoprivrednim zemljištem važno je s aspekta podizanja konkurentnosti hrvatske poljoprivrede. Briga o očuvanju kvalitete poljoprivrednog zemljišta ima posebno mjesto u Zajedničkoj poljoprivrednoj politici Europske unije, odnosno Strateškom planu Zajedničke poljoprivredne politike Republike Hrvatske 2023.-2027. kojim Hrvatska kroz tri programske sheme i niza intervencija treba doprinijeti preobrazbi Europe u moderno, resursno učinkovito i konkurentno gospodarstvo. U Hrvatskoj, poljoprivrednici koji su u sustavu dobivanja poticaja, koriste oko 1.500.000 ha poljoprivrednog zemljišta. Najveći dio korištenog poljoprivrednog zemljišta (53,2 %) nalazi se u vlasništvu poljoprivrednika koji ga sami koriste, a 34,3 % poljoprivrednog zemljišta koristi se temeljem zakupa, dok ostalo čine drugi ugovorni oblici korištenja tuđeg zemljišta. Agencija za plaćanja u poljoprivredi provodi redovito i sustavno opažanje, praćenje i procjenu poljoprivrednih djelatnosti i praksi na poljoprivrednim površinama pomoću satelita Copernicus Sentiel 1 i 2, u vlasništvu EU, s ciljem donošenja intervencijskih prilagodbi za unaprjeđenje korištenja poljoprivrednog zemljišta i okoliša.Good management of agricultural land is important from the aspect of increasing the competitiveness of Croatian agriculture. Concern for preserving the quality of agricultural land has a special place in the Common Agricultural Policy of the European Union, i.e. the Strategic Plan of the Common Agricultural Policy of the Republic of Croatia 2023-2027. by which Croatia, through three program schemes and a series of interventions, should contribute to the transformation of Europe into a modern, resource-efficient and competitive economy. In Croatia, farmers who are in the incentive system use about 1,500,000 ha of agricultural land. The largest part of the used agricultural land (53.2%) is owned by the farmers who use it, and 34.3% of the agricultural land is used on the basis of a lease, while the rest is made up of other contractual forms of using another people's land. The Agency for Payments in Agriculture conducts regular and systematic observation, monitoring and assessment of agricultural activities and practices on agricultural land using the Copernicus Sentiel 1 and 2 satellites, owned by the EU, with the aim of making intervention adjustments to improve the use of agricultural land and the environment

No full textCilj ovog završnog rada bio je istražiti učinak predtretmana kapronskom kiselinom na otpornost klijanaca uljanog lana u uvjetima solnog stresa izazvanog natrijevim kloridom. Predtretman sjemena izvršen je močenjem sjemena u vodi, 0,5 mM i 1,0 mM otopinama kapronske kiseline u trajanju od 30 minuta, dok je za izazivanje solnog stresa sjeme naklijavano 7 dana na podlozi sa 100 mM otopinom natrijeva klorida, nakon čega su izmjereni klijavost sjemena, dužina korjenčića i stabljičice te ukupna dužina i masa klijanca. Istraživanje je pokazalo da je predtretman sjemena uljanog lana 0,5 mM kapronskom kiselinom u uvjetima bez stresa imao pozitivan učinak na sve ispitivane parametre, dok je u slučaju predtretmana sjemena 1,0 mM otopinom kapronske kiseline utvrđen negativan učinak, osim na postotak klijavosti sjemena. U slučaju kada je sjeme lana izloženo uvjetima solnog stresa, predtretmani ispitivanim otopinama kapronske kiseline pokazali su pozitivan učinak na otpornost klijanaca uljanog lana. Iz dobivenih rezultata može se zaključiti da bi se 1,0 mM kapronska kiselina mogla koristiti za predtretman sjemena uljanog lana, a u svrhu povećanja otpornosti klijanaca uljanog lana na solni stres.The aim of this thesis was to investigate the effect of caproic acid pretreatment on the resistance of oilseed flax seedlings under conditions of salt stress caused by sodium chloride. Seed pretreatment was performed by soaking the seeds in water, 0.5 mM and 1.0 mM caproic acid solutions for 30 minutes, while to induce salt stress, the seeds were germinated for 7 days on a medium with 100 mM sodium chloride solution, after which the seed germination, root and stem length, and total seedling length and weight were measured. The study showed that pretreatment of oilseed flax with 0.5 mM caproic acid under stress-free conditions had a positive effect on all tested parameters, while in the case of seed pretreatment with 1.0 mM caproic acid solution a negative effect was found, except for the percentage of seed germination. In the case when flax seeds were exposed to conditions of salt stress, pretreatments with the tested solutions of caproic acid showed a positive effect on the resistance of oilseed flax seedlings. From the obtained results it can be concluded that 1.0 mM caproic acid could be used for pre-treatment of oilseed flax, in order to increase the resistance of flax seedlings to salt stress
