Type of Report: COMPLETION REPORT Period Covered: 3 years Title of Project: Mijenjanje kakvoće polovica upotrebom hibridnih nerastova i krmača u obiteljskim gospodarstvima AZ – 39 – 98 Contract Number: November 2, 1998. Project Start Date: prof. dr. Marija Đikić Investigator Participating Institution: Faculty of Agriculture, University of Zagreb Zagreb, December 4, 2001. (date) Prof.dr. Marija Đikić (Investigator) 1 Subject of Research Family farms in Croatia pariticipate in pig production of Croatia with 80%. Previous research on slaughtering line showed that the quality of fattened pig halves produced on family farms have low relation between muscles and fat tissue when compared to big farms or developed countries. Research set by this project was in direction of producing fattened pigs on family farms, by using hybrid boars and sows, and the result would be pig halves with higher share of muscles and lower share of fat (according to SEUROP system), what would influence the energey value of halves. Differences between energy value of muscular and fatty tissue affect the production efficiency through energy consumption, because for 1 kg of muscles 9,73 MJ ME is needed, while in the same time, for production of 1 kg of fat 53,2 MJ ME is used, what makes direct difference in cost of feed in fatteneing. Besides that, possibility of participating of family farms in pig breeding (by carrying out the Plan and Program for Pig Breeding, Jurić et al., 1997, HSSC), that is to produce highly selected parent stock (PS) or even grand parents (GP) units for breeding. Purpose of the research is to use the obtained data as a base for establishing the prospective ans competitivenes of pig production on family farms in realtion to the EU and CEFTA countries ad the world market of pig meat, as Croatia is a member of WTO. This research shold also inicate the importance of evaluation of halves on slaughtering line acording to S-EUROP classes, that is according to share of muscles in carcass, what would be a stimulation for the development of breeding and productive pig science in our country. Description of Technology Pig production is an agricultural activity that in developed countries has the characteristics of highly specialyzed idnustry industry, regarding selection and breeding of breeding material and production of fattening pigs. Pig selection and breeding is taken over by mulinational breeding companies, which, by using knowledge of geneticians in molecular, popualtion, quantive and biometric genetics and sophisticated equipment, create nucleus – genotypes of breeds and synthetic lines. This animals are than offered with high profits to breeding material market and for their multiplication and usage in production (according to demand of particular market) they give schemes 2 of usage – most commonly scheme of hybrid breeding program, but with nucleus under sole supervision of the company. Plan and Program of Pig Breeding set in 1997 is still valid in Croatai and according to it, procedures in breeding and selection should follow hybrid program of three- and four-line mating. Selection should take part in nucleus herds by multiplication through grand-GP, GP and PS lines and production of fattened pigs (chapter 7 and 8, p. 16-28). Program stipulates the usage of breeds (Sweedish Landrace, Big White, Belgian Landrace, Duroc, Hempshire, German Landrace, Pietren), and recognized hybrid lines, either from domestic or foreign (imported) selection. In Brodsko - posavska and Sisačko – moslavačka Counties, family farms (some of them are co-operatives of Klas, Nova Gradiška and Poljoprerada, Zagreb) and Cage Okučani and Klas, Nova Gradiška slaughter houses were involved in carriynig out of the experimental part of the project (their animals and labor). According to the subject of research, the following was examined through experiments (methods described in details the VIP Project Report of December 19, 1999): 1. possibility that family farms participate in pig breeding through production of highquality breeding material of PS hybrid sows. Reproductive properties and litter size of D-line Hypor sows mated with C-line Hypor boar was examined. D sows and C boars are Hypor GP lines directly imported form the Dutch breeding company Nutreco – Euribrid, highly selected for production of female CD PS-line used for production of comercial fattenig pigs. 2. possibilities of family farms to produce quality fattened pigs by using hybrid boars and sows. By mating PS lines of Hypor boars AB and CD sows, ABCD hybrid fattened pigs were produced. By Uporabnim križanjem of AB boars and Sweedish Landrace (SL) sows ABSL crossbreds were produced (Sweedish Landrace is domestic selection of Dubravica line). SL fattened pigs were produced in pure blood. Same AB boars were mated with CD and SL sows to establish changes in quality of halves of fattened pigs when hybrid boars are used. Fattening was carried out in classic technology using feeds ST1 and ST2 produced by Klas, Nova Gradiška, with ad libitum feeding and watering. Quality of halves was assesed on slaughtering line by the two-point 3 method and classes were evaluated according to S-EUROP system (Pravilnik, NN 119/99) and, partially, by dissection according to Weniger, 1963. 3. In 1999, with purpose of investigating the competitiveness of pig production on our big and family farms in relation to the developed countries of EU (Baldwin C.P, 1999), quality of halves of fattened pigs from so called “free buying”, produced on family farms which are independent breeders and producers of breeding and fattening pigs, was examined on slaughtering line. For the analyses, a part of HSSC data was used – annual report for 1999 and 2000. Besides that, quality of halves of fattened pigs produced from piglets imported by Klas from Hungary (average weight of 25 kg) was also investigated on slaughtering line. On one of the family farms, piglets form Hungary and the domestic ones (Klas, N. Gradiška) were simulateously fattened by using classic technology. Economic Analysis (Profitability) In proposal of this project it was not planned to analize economic parameters of the whole technology process of production. However, for economic analysis, litter size, number of weaned piglets and quality assesment on the slaughtering line according to muscle share are important indicators of success of production. Table 1 shows litter size and number of weaned piglets for D sows from the experiment on family farm and the data for farms recorded by HSSC.

Table 2 gives the data on quality of halves of fattened pigs with different genetic base. Values are given in DEM / kg of fattened pig, calculated according to system of payment some meat processors use for payment on slaughtering line (“Vajda”Čakovec, Danica, Podravka).

System of payment in Vajda – Čakovec pig farm Agromeđimurje – Čakovec and Danica-Podravka is: Value of DEM/1 kg liveweight of fattened pig = (0,21 kn x % muscular tissue in halves) 3,81 kn Value of DEM/fattened pig = slaughtering weight, kg x value DEM/1 kg liveweight In system of evaluation according to muscle percentage in halves on slaughtering line (classes), obtained values in DEM/kg indicate that genetic base (back fat and m.l.d. thickness) influences the efficiency of production, although, in this case of calculation, slaughtering weight had big influence on value of fattened pig in DEM. However, it would be better to estimate value of the pig half directly according to the percentage of muscles and influence of the weight asses through the difference in weight between group I, II and III, as defined in article 6 of the Regulation NN 119/99. This way meat processing industry could directly influence quality of halves in relation to purpose of processing and pig producers would be more effective in fattening, having in mind the genetic base of pigs and finishing weight, because through energy value of muscle and fat tissue they could regulate the efficiency of production by means of feed 5 consumption per pig. As in Croatia it is hard to implement evaluation system on slaughtering line according to share of muscles in halves, Table 3 shows differences between groups of fattened pigs with low and high share of muscle tissue in halves to illustrate the importance of this issue. In the same time, data show the neccessity of usage of hybrid boars selected for high percentage of muscles in changing the quality of fattened pig halves.

This would stimulate the market of genetically more quality breeding material and stert the change in the present system of stimulation for fatteneing pigs (90 kn/tovljeniku) and breeding material. 6 Applicability It is possible to involve family farms, which are now traditionally in pig production, in breeding of quality breeding material. But, for production of quality breeding material and fattening pigs, farms that have no previous experience should be connected to systems as company farms, feed producers, slaughteries or HZSPS or HSSC officers working on field. Evaluation by Farmers Family farm owners that are co-operators of big systems are satisfied with present situation, because big systems are taking care for the input and output in production of breeding material and fattening pigs. They say that for them, market is functioning and in that way they can take part in breeding and fattening of pigs on international level. But, by visiting family farms in Brodsko – posavska County, we have found that many farms with 10 ha or more of land wish to become an independent producers of fattening or breeding pigs and in that way to use feed (cereals) produced by themselves.However, the limiting factor are financies and some of them have no experience in pig production, but belive that they could increase the income significantly with this production. Quantitative data During the Project, six trials were carried out and the data are mostly processed and partially published. Besides that, data for sows per breed in stockbook from HSSC were analyzed and compared, as well as number of family farms and meat percentage for fattening pigs on company farms as given in 2000 Report of HSSC. Tables, according to the Regulation NN 119/99 for DT method, for estimation of meat percentage on slaughtering line were created to be used by family farms. As Croatia faces strong competition in pig production, due to membership in WTO, CEFTA and EU, Table 4 gives parameters which developed countries take into account when talking about succes and competitiveness in pig production. 7 Table 4 Characteristics of pig industries in Croatia and developed countries EU Parameter Developed countries* Hrvatska – Croatia** Company Family farms farms Denmark France Netherlands Germany G.Britain n 20,2 17,7 18,7 17,7 20,6 15,0 16,87 kg 1515 1478 1607 1469 1349 1158 1550 kg 905,97 833,53 891,88 807,9 782,43 623,57 742,94 FCR (to 100 kg) kg 3,24 3,18 2,86 3,21 3,03 3,64 - Carcass weight kg 75 84 86 83 66 77,17 91,92 Muscle tissue in carcass % 59,8 56,4 55,5 55,0 58,0 53,87 47,91 E E E E E U R Pig sold/ sow/ year Pig meat sold/ sow/ year (in carcass) Lean sold/ sow/ year Class * ** Source: Baldwin C.P. 1996; Daumas G. 1996 Source: Estimated towards of CLSC and investigated results (1999 and 2000) 8 Qualitative data In the sense of prospective of the development of pig production on family farms it is necessary to establish closer co-operation with the officers of HZZPS and HSSC. Besides that, it is important ot pass stimualting regulations for stimulation of the development. It has to be pointed out that tissue ratio in halves of fattened pigs produced on family farms is one of the reasons for inefficiency of pig production. Having in mind that 180.000 sows kept on family farms could produce 2 milion fattened pigs per year, than the inefficiency calculated through energy value of halves, due to tissue ratio, gives pure loss of 95 mil. DEM. There is a big problem in volume of pig production in Croatia (indicated by data in Table 4 and research Future production of milk and meat in Croatia, Đikić and Jurić, 2001) and if the comsumption of pig meat per capita in Croatia is on the present Europen level, than the present production should rise by 89%. In developed countries there is more and more research on tissue quality in pig halves and it is necessary to start this kind of researck in Croatia, too.

Conclusion: Usage of hybrid boars and sows selected for high meatness in production of fattening pigs on family farms could enable production of pig halves with high percentage of muscles and high classes according to S-EUROP system, but having in mind technology of fattening. By production of halves with high muscle percentage, efficiency of pig productin could be affected and not only that pig meat production would be increased, but competitiveness of Croatian pig production in relation to developed countries, too. It is necessary to implement evaluation system on slaughtering line according to muscle share in halves to stimulate development of breeding and productive pig production in Croatia. Part of that could make family farms that participate in Croatian pig production with 80%. 11
