Objective of this paper was to evaluate phenotypic variability of carcass side traits and quality of meat of fatteners (male castrated heads) of Moravka breed (M) and Mangalitsa (swallow-belly Mangalitsa - LM). The quantity and content of meat were determined based on dissection of left carcass sides (Walstra and Merkus, 1996). Also, nutritive properties of musculus longissimus dorsi (m.l.d.) were established. Obtained data were processed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Results of the study show that Moravka fatteners had longer carcass sides (+6.82 and + 5.00 cm) compared to Mangalitsa breed, corrected to average body weight at slaughtering. Fatteners of M breed had in average higher total mass of back-loin part (+0.685, P<0.05) and average quantity of muscles in the same part of carcass side (+0.631 kg, P<0.01), compared to fatteners of LM breed. Also, they had higher quantity of muscle in belly-rib part (+0.237 kg, P<0.05) compared to LM. Share of muscle tissue in back-loin and belly-rib carcass side parts corrected for WCC, was higher in M carcass sides than in LM (P<0.01). Conversely, muscle tissue content in shoulders of Mangalitsa was higher (+4.8% ; P<0.05) than in Moravka. Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides. In m.l.d. of Moravka water content was higher (+6.1%, P<0.01), content of total lipids (-6.5%, P<0.05) and cholesterol (-19.68 mg/100 g, P<0.001) was lower than in Mangalitsa.

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;

Abstract. This study was conducted to determine the effect of genotype and fattening system on carcass measurements of lambs and technological properties of the male lamb meat (Musculus longissimus dorsi, MLD). The animal material in the study included 39 Hemşin (H) and 39 Tuj (T) male lambs. Extensive (E), semi-intensive (SI) and intensive (I) fattening systems were applied in the study, which was completed within 90 d. In the E, SI and I fattening groups, a total of 48 lambs, including 16 lambs in each group, were slaughtered. The results of the study indicated that the effect of genotype on the first-hour yellowness (b*), being one of the colour parameters of the MLD, and the effect of the fattening system on 1 h hour redness (a*) and chroma (C*), being among the colour parameters, were statistically significant (P<0.05). The effect of genotype and fattening system on MLD pH at 45 min (pH45 min) and 24 h (pH24 h) after the slaughtering and on the third and seventh hour drip loss (DL %) was statistically nonsignificant (P>0.05). The effect of genotype and fattening system on DL, cooking loss (CL %) and texture (TT) was nonsignificant (P>0.05), whereas the effect of these factors on water-holding capacity (WHC %) was significant (P<0.05). The effect of genotype on external carcass length (ECL), internal carcass length (ICL), internal hindquarter length (IHL), and carcass and leg conformation was statistically significant (P<0.05). The effect of the fattening system on all the carcass measurements except for carcass conformation, carcass depth (CD) and external chest width (ECW) was statistically significant (P<0.05). Genotype and fattening system affected the colour and some quality traits of meat and carcass measurements of lambs.
