EQUATIONS FOR LEAN SHARE ESTIMATION IN SWINE CARCASSES IN CROATIA

The experiment was performed on 144 pig carcasses selected on the basis of backfat measures obtained by “ZP”- method. There was no stratification according to the carcass weight. One day after slaughter the carcasses were dissected by to EU reference method. The lean share was calculated by equation prescribed by European regulation (Commission Regulation No 3127/94) and estimated by six equations. The first one (MP1) is prescribed by current Croatian regulation (N.N. 119/1999) and the other five were developed on the basis of original data obtained by the experiment. The meat percentage estimated by equation MP1 differed statistically (p<0.01) from mean meat percentage obtained by EU referent method; the current formula significantly overestimates the meatiness of pig carcasses from Croatian population. Original measures of fat and muscle measured for “ZP”- method were used as independent variables in equation MP6. In order to improve the accuracy of estimation, transformed variables were used in equations MP2-MP5. Additional measure of warm carcass weight (T) was included as an independent variable to equations MP4 and MP5 but this did not improve their accuracy. Equation MP2 to MP5 satisfy the statistical criterion requested by EU regulations. The equation MP2 and MP5 can be recommended for lean share estimation in pig carcasses of Croatian pig population

The effect of sires on daily gain and fat thickness

The production characteristics of fatteners in this paper were examined in two farms of pigs in the Republic of Serbia. The research included 1166 pigs of both genders (female animals and male castrated heads) with various genotypes. Research examined influence of sire breed, sire within sire breed, gender of the pigs and the mass at the end of the fattening on the following characteristics of the fatteners: Daily gain of the warm carcass side mass (PTP), rump fat thickness (DSK), backfat thickness (DSL) and sum of the fat thickness rump+back (DSKL). The pigs in this research come from the following sires: Large White (LW), Swedish Landrace (SL), Duroc and Crossbreed H × D. Data processing was done using the Harvey computer program. It was determined that all the involved effects in the model show a different level of influence on the researched traits (P lt 0.05; P lt 0.01; P lt 0.001), whereas only one factor, sire within sire breed H ×. D does not influence the expression of the characteristic gain of the warm carcass side mass (P > 0.05)

Comparative testing of slaughter traits and meat quality of male and female Simmental cattle

The paper presents the results of comparative testing of slaughter traits and meat quality of male (A) and female (B) young cattle of domestic Simmental breed. The sample included a total of 30 heads, 15 in each group. Cattle were slaughtered at the same age with an average mass of about 660 kg in the group (A), and about 500 kg in the group (B). The study results show that cattle of group (A) achieved statistically (p<0.001) significantly higher share of pre slaughter mass and mass of warm carcass sides while female cattle achieved statistically (p<0.01) significantly higher share of kidney fat. The share of tissues in the three rib cut showed statistical differences between the groups, in the share of the M. longissimus dorsi that was statistically (p<0.05) significantly higher in male cattle and the share of fat was statistically (p<0.01) significantly higher in group (B). The chemical composition of M. longissimus dorsi statistically (p<0.05) differed significantly in the share of water which was higher in male cattle while the cattle of group (B) had statistically (p<0.01) significantly higher share of lipids. As for the technological quality, cooking loss of M. longissimus dorsi was statistically (p<0.01) significantly higher in young cattle of group (A), while the tenderness/softness of M. longissimus dorsi (p<0.01) was significantly better in young cattle of group (B). Sensory characteristics of M. longissimus dorsi differed statistically (p<0.001) significantly in the tenderness of the meat that was better in young cattle of group (B). Male Simmental cattle had better slaughter performance and meat quality characteristics, except tenderness of meat which was better in female cattle

Korupcija i suzbijanje korupcije u RH

Tema ovog članka je korupcija u Hrvatskoj i aktivnosti koje su Vlada Republike Hrvatske i druga tijela vlasti, udruge i građani kao pojedinci poduzeli na suzbijanju korupcije njezinom otkrivanju i sankcioniranju. Korupcija potkopava i razara mnoge vrijednosti i stoga se smatra velikim zlom koje se, ako se ne suzbija, širi i raste do neslućenih razmjera. Svjesna ozbiljnosti problema korupcije Vlada RH odlučna je u svojim nastojanjima da iskorijeni korupciju iz društva. Sprječavanje korupcije na svim razinama ključ je uspješne antikorupcijske politike, ali i obveza RH koja proizlazi iz Konvencije UN-a protiv korupcije, te relevantnih dokumenata Vijeća Europe i Europske unije

Carcass quality of chickens of different conformation

The aim of this study was to investigate the effect of conformation of chickens of different genotype on the yield of breast meat. As a typical example of the chickens of very poor conformation pure breed Naked neck chickens were taken, fattened 8 and 10 weeks (groups K8 and K10). As an example of good conformation, an imported hybrid of chickens was taken, known for its broiler qualities and as medium growing hybrid, Red Bro (R). The second experiment included commercial hybrids of fast growth (Ross, Cobb and Hubbard) reared according to all technological standards of intensive fattening until the age of 42 days. The results obtained were contrary to the conclusion obtained a few decades ago, at the beginning of the study the conformation of chicken, by Scots and Darrow (1953), according to which the selection of chickens of heavy type, despite the fact that, to some extent, it had improved meat yield of the breast, did not significantly improve slaughter traits of fattening chickens, confirming that better conformation and higher body weight had a positive impact on improving relative share of breast, i.e. white meat. The results regarding the slaughter traits of chicken genotypes of different conformation suggest that breeding - selection work to improve the conformation of broilers significantly improved slaughter yields and breast meat yield. In this sense, the conformation can be treated as an indicator of the slaughter value of carcasses, rather than an aesthetic category

Motivation to Follow a Career in Dentistry of Students in Three South-East European Countries

Uvod: Željelo se istražiti i usporediti čimbenike koji su potaknuli studente na studij stomatologije uzemljama sličnog okružja (Albanija, Hrvatska i Republika Sjeverna Makedonija) i procijeniti je li se njihova motivacija tijekom godina promijenila ili ne.Materijal i metode: U 2014./2015. Godini provedenasu poprečno-presječna istraživanja (cross-sectional) na državnim stomatološkim fakultetima u Tirani(Albanija), Zagrebu (Hrvatska) i Skoplju (Makedonija) kako bi se procijenilo stajalište studenata o njihovoj motivaciji za karijeru. Dobrovoljno i anonimno sudjelovali su studenti stomatologije s prve, trećei završne godine. Upitnik s pet stavki preveden je na jezike zemalja sudionica. Etičko odobrenje daloje Etičko povjerenstvo Sveučilišta sveti Ćiril i Metod iz Skoplja. Chi kvadrat testom ispitano je postojeli statistički značajne razlike u odgovorima između studenata u trima državama i između godina studija.Rezultati: Ukupno je bilo uključeno 739 ispitanika (319 u Tirani, 211 u Zagrebu i 208 u Skoplju).Razlike u odgovorima studenata prve godine u svim trima zemljama bile su statistički značajne (χ2 = 82,65; p < 0,01). Najintrigantnije je bilo pitanje o pritisku roditelja da studiraju stomatologiju nakoje je najviše pozitivnih odgovora bilo u Tirani (čak 27,7 %). Pozitivna slika bio je najčešći odgovorzagrebačkih studenata (do 79,7 %), ali se smanjuje od prve do posljednje godine u Skoplju. Takođersu postojale značajne razlike između fakulteta unutar trećih i posljednjih godina studija.Zaključci: Pozitivna slika stomatološke profesije bila je glavni razlog za upis na svim trima fakultetima – tako jeodgovorilo čak 97 % studenata na završnoj godini u Hrvatskoj, članici Europske unije (EU). U dvjemadržavama koje nisu članice EU-a (Albanija, Sjeverna Makedonija) činilo se da stomatološka profesi-ja nema tako dobar status, a očekivanja studenata se ne ispunjavaju, posebno u Skoplju (čak 33,9 %spremno je promijeniti zvanje i njih do 64,5 % izgubilo je motivaciju za studij). Jedna od strategija zapoboljšanje stanja mogla bi biti uključivanje više kliničke prakse i bolja organizacija pojedinih studijaObjective: To investigate and compare the factors that motivated students to study dentistry in countries with similar background (Albania, Croatia and the Republic of Northern Macedonia) and to as-sess whether or not their motivation changed during time. Material and methods: In 2014/2015,cross-sectional studies were conducted in state funded dental schools in Tirana (Albania), Zagreb(Croatia) and Skopje (North Macedonia) to assess student views on their career motivation. All den-tal students from the first, third and final years of study were invited to participate. The participationwas voluntary and anonymous. A five-item questionnaire was translated into languages of the par-ticipating countries. Ethics approval was granted by the Ethics Committee of the University of SaintsCyril and Methodius, Skopje. The Chi square test was used to test if there were statistically significantdifferences in answers between students in 3 countries, furthermore between years of the study.Re-sults: The total number of respondents was 739 (319 in Tirana, 211 in Zagreb and 208 in Skopje) Thedifferences in the answers between the first-year students from all three countries were statistical-ly significant (χ2=82.65; p<.01). The most striking answer was to the question on parents’ pressureto study dentistry, which was far more frequent in Tirana (up to 27.7%). A “positive image” was themost frequent response from students from Zagreb (up to 79.7%), but it declined from the first to thefinal year in Skopje. There were also significant differences the schools within the 3rdand final years of study. Conclusions: A positive image of dental profession was the main reason for students studying dentistry at all three schools; as many as 97% of the students of the final year in Croa-tia, a member of the European Union (EU). In the two non-EU countries (Albania, North Macedonia) itseemed that dental profession does not have such good status and student expectations are not be-ing fulfilled, especially in Skopje (up to 33.9% willing to change their vocation and up to 64.5% losttheir motivation to study) One of the strategies to improve the situation could be to include more clinical practice and to better organize the study
