The beneficial effect of acorn on blood lipid level could be linked with presence of both high tannin content (70.10 g/kg DM) and high amounts of unsaturated fatty acids (more than 80%) such as linoleic (43.38%), oleic (30.52%) and alpha linolenic (4.58%) acid. In this study the influence of ad libitum acorn intake on blood lipid profile and longissimus muscle (MLD) composition of Black Slavonian pig were investigated and compared with the effects of commercial corn based diet. Acorn consumption in last three weeks of fattening period had a decreasing effect on triglyceride and total cholesterol concentration in blood without adverse effect on liver function. Compared with the intake of corn based diet, the intake of acorn resulted in 11% (0.22 mmol/l) lower total cholesterol (P 0.05) among finishing diets for any histochemical characteristics, except for diameter of intermediate fast-twitch oxidative-glycolytic (FOG) fiber types (58.10 µm and 51.67 µm in acorn and corn based fed pigs, respectively; P < 0.01). The trend toward lower proportion (10.80 vs. 12.36%) and smaller diameter (59.36 vs. 64.57%) of red slow-twitch oxidative (SO) fiber types (P < 0.08) was observed in acorn than in corn-based fed pigs.

Some carcass traits and muscle fiber characteristics of m. Longissimus dorsi (MLD) in pigs of Turopolje breed (T) and crossbreds TCSL were analyzed. The hogs T (n = 19, 568 ± 20 days) and TCSL (n = 10, 575 ± 27 days) were progenies of the same boar, T3HB, and sows of Turopolje breed and crossbred CSL (♂C Hypor line × ♀SL, Swedish Landrace). All pigs were reared and fattened in the outdoor system, according to traditional Croatian technology of low input. Live (LW) and carcass weight (CW) and some carcass traits and chemical composition of muscle and fat tissues were analyzed. In the carcass, the lean percentage (L%) was calculated on the basis of back fat thickness (BF) and MLD thickness, according to “two point” method (CRO, Regulation, NN 85/05). The samples of MLD from the left side at the 13/14 th rib level were taken after slaughtering (5 min.) and frozen in liquid nitrogen until histo-morphological analysis (diameter of slow twitch oxidative, SO; fast twitch glycolytic, FG; and fast twitch oxidative, FOG fiber types). After chilling carcass (24 h, at + 4 oC), the samples of MLD and the belonging back fat were taken from the same place for analysis of chemical composition (water W, protein P, lipid L, ash A). According to the estimated results the pigs of Turopolje breed and TCSL significantly differed as follows: LW (95.31 and 117.10 kg), CW (77.11 and 97.50 kg), BF (31.68 and 28.00 mm), MLD dept (50.16 and 60.10 mm), L (45.25 and 47.69%), SO (33.69 and 44.24 µm), and FG (38.48 and 47.60 µm). The chemical content of muscle and fat tissues was not significantly different between investigated pigs.

An analysis was made of baby beef [veal calves] destined for export to Italy. Data were obtained on 26 half-carcasses. Half-carcass weight averaged 129.2 kg, the percentage of rump was 30.5, the percentage of back and shoulders was 23.1, and the remainder accounted for 44.4%. In the rump, the percentage of meat, fat, bone and connective tissue was 76.1, 5.2, 13.3 and 5.4, respectively. Corresponding percentages for the loin were 68.5, 5.4, 20.4 and 5.8. A graph of carcass cuts and their nomenclature in Croatian was given.

Cilj je rada istražiti mase i preživljavanje prasadi Turopoljske pasmine i križanaca TCSL kroz sedmodnevana razdoblja od 1. do 42. dana života prema distribuciji porodnih masa. Prasad T i TCSL bili su potomci nerasta Tmb3 i krmaca T i križanki CSL (C m. rod. lin. Hypor x SL, krmace pasmine Svedski Landras), a proizvedeni su po tradicionalnoj hrvatskoj tehnologiji niskog inputa u otvorenom sustavu držanja, biocenoza sume hrasta lužnjaka i mocvarnih livada u podrucju Turopolja. Mase prasadi utvrđene su pojedinacnim vaganjem 1. ( porodna masa), 7., 14., 21., 28., 35. i 42. dan života. Rezultati i razlike analizirani su između T i TCSL skupina unutar pojedinih razreda distribucije porodnih masa i sedmodnevnih razdoblja ( t-test, SAS, 1999). Distribucijom porodnih masa utvrđeno je u skupinama T i TCSL 29.4 i 61.5% s manjom, 35.3 i 15.4% u granicama te 35.3 i 23.1% prasadi s vecom masom u odnosu na prosjecnu porodnu masu, 1.25kg, koja je standardna vrijrdnost za svojstvo porodne mase prasadi kod T pasmine. Mase prasadi TCSL u odnosu na T bile su znacajno razlicite (p<0.05) u razredima distribucije porodnih masa 1.2-1.3kg 14. i 21. dan života, a u razredu 1.3-1.4kg 14., 21., 28., 35., i 42. dan života. Prosjecne mase po sedmodnevnim razdobljima između skupina TCSL i T bile su razlicite samo 21. dan života. Preživljavanje prasadi T i TCSL od 1. do 42. dana života bilo je 73.5 i 84.6%.
