ORIGINAL_ARTICLE Critical indicators of intensive production in hog raising are continuity of production, high level of produced series-tours, application of the most contemporary technological achievements without any turnover of capital, high merchandise turnover, and intensive usage of the reproduction potential of breeding material. Production of piglets represents one of the most essential phases in the production of pork meat. In spite of genetic factors, duration of interval wean-conception is one of the basic factors in determination of bringing forth indexes and number of piglets per litter. In order to recognize production costs of piglets completely we found nutrition costs for piglets and sows represent 61%, while other costs such as personal incomes, veterinary services, water, energy, losses, and amortization represent 39% of total costs. On the basis of cost price per feeding day of a sow and the number of piglets per litter, production costs of piglets older than 28 days with an average body weight of 7 kg were determined. Price cost per piglet after weaning, with 7 kg average body weight, and 146 days of reproduction process accounts for 21,78 EUR if there are 10 piglets in a litter. If the reproductive cycle would last exactly the same and if successful conception would be achieved 25 days after weaning, production cost per piglet would be 23,79 EUR. https://macvetrev.mk/Files/Article/2019/10.1515/macvetrev-2016-0090/macvetrev-2016-0090.pdf 2016-10-15T09:00:00 233 238 10.2478/macvetrev-2016-0090 economy production of piglets litter size nutrition Milorad Mirilović mija@vet.bg.ac.rs false 1 Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobodjenja 18, Belgrade, Serbia LEAD_AUTHOR Branko Velebit false 2 Institute of Meat Hygiene and Technology, Kacanskog 13, Belgrade, Serbia AUTHOR Spomenka Djurić false 3 Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobodjenja 18, Belgrade, Serbia AUTHOR Branislav Vejnović false 4 Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobodjenja 18, Belgrade, Serbia AUTHOR Mirjana Dimitrijević false 5 Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobodjenja 18, Belgrade, Serbia AUTHOR Nada Tajdić false 6 Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobodjenja 18, Belgrade, Serbia AUTHOR Dragan Rogožarski false 7 Veterinary Specialist Institute “Pozarevac”, Dunavska 89, Pozarevac, Serbia AUTHOR Wolf J, Wolfovà M, Genetic parameters including the service sire effect for the sow traits stillbirth and piglet losses in Czech Large White and LandraceCzech Journal of Animal Science 2012; 57: 9402-409. 1 Menčik S, Vuković V, Modrić M, Špehar M, Ostović M, Sušić V, Štoković I, Samardžija M, Ekert Kabalin A, Prlr-Alui gene Polymorphism and litter size traits in highly prolific line of topigs 20 SowsActa Veterinaria 2015; 65: 4463-476. 2 10.1515/acve-2015-0039 Mirilović M, Tešić M, Pejin I, Rogožarski D, Krstić B, Economics and management in hog raisingContemporary Agriculture 2012; 61: 3-4192-198.In Serbian 3 Vlahović B, Štrbac M, Trends in pig meat production in EuropeContemporary Agriculture 2008; 57: 1-270-76.In Serbian 4 Quendler E, Podiwinsky C, Baumgartner J, Winckler C, Boxberger J, Performance, labour and economic aspects of different farrowing systems.
