To this end, a total of 720 pigs were measured in one abattoir. One can say from the results that the correlations between correct and surrogate measurements of fat depth are high (0.95-0.98), for muscle thickness they are lower ranging from 0.49 to 0.88, and for lean meat percentage they are in the range of 0.85-0.95. The lowest correlation (0.49) was calculated for muscle depth measurement between the 2nd and 3rd last rib when the place of measurement was moved 1 cm in the caudal direction, which influenced the level of the FOM correlation. It was further demonstrated that for the second insertion the differences in lean meat percentage prediction ranged from -6.07% to +9.29%. It was also demonstrated that various instruments provided identical measurements of fat depth (r = 0.57-0.97), while for muscle depth the performance was worse (r = 0.38-0.78), which caused a fluctuation in the prediction of lean meat percentage with differences ranging from -2.56% to +2.81%. It can also be concluded that a high agreement between operators was demonstrated for the determination of lean meat percentage (r = 0.71-0.80).

Feed and water were available ad libitum. Individual live weights were recorded on days 45, 90 and 135 of the experiment. Feed consumptions were recorded weekly. Blood was drawn from the anterior vena cava of each pig at day 135 for the determination of serum biochemical parameters. During the first 90 days of the experiment pigs from the Cp group had higher body weight gain (BWG) compared with the control group (+2.5% and +7.0%, respectively) but in the finishing phase of growing their growth parameters were significantly lower (-4.8%). Blood serum biochemical parameters from all experimental pigs were generally within the normal range. Higher triglyceride concentration, lower total cholesterol concentration and increased activity of AST were recorded in the serum of the Cp group.

In 10 rabbits the basal diet was supplemented with Se-enriched yeast to increase the Se concentration to 0.50 mg/kg. Rabbits were slaughtered at the age of 11 weeks. Samples of meat, liver and hair of 4 rabbits from each group were taken and analyzed. No effect of Se on growth, feed conversion and dressing out percentage was observed. Loin and hindleg meat, liver and hair of control rabbits contained 93, 98, 521 and 267 μg Se/kg, respectively (average values). In treated rabbits the corresponding Se concentrations were 400, 389, 1 414 and 914 μg/kg. Supranutritional Se supply had no effect on the activity of glutathione peroxidase in meat, and oxidative stability of meat expressed as production of thiobarbituric acid-reactive substances in meat stored for 3 and 6 days. Thus, the enrichment of meat with Se is the main benefit of Se supplementation of rabbit diets.

The content of corpuscular particulates of various origin (dust, bacteria, fungi), ammonia and carbon dioxide was determined. The investigations were conducted in a poultry house on a family farm in the area of moderate continental climate during spring 2006. The air concentration of bacteria ranged from 1.7 × 104 to 2.2 × 105 cfu/m3, of fungi from 9.8 × 103 to 8.5 × 104 cfu/m3, of dust from 1.8 to 4.8 mg/m3, and of ammonia from 4 to 27.47 ppm. Total dust and fungi concentrations measured at the end of fattening period were almost identical to the initial ones, whereas the concentrations of bacteria and ammonia showed a sinusoidal rise from the beginning to the end of fattening period. In general, the analyzed air pollutants reached relatively high levels in the mid-fattening period and also show significant differentiation between fattening periods as demonstrated by t-test yielding statistical significance at a level of P < 0.05.

The forages differed in the content of macrominerals (Ca 15.82-3.66 g/kg DM; Mg 3.68-1.46 g/kg DM; Na 0.20-3.02 g/kg DM; K 21.57-34.79 g/kg DM), and large differences (P < 0.01) were also in the element release in the rumen between experimental forages. The lowest DM effective degradability was determined for grass forages (49.5%-51.5%) and forages from legumes had higher degradability (62.9%-67.1%). The extent of disappearance of macroelements was also higher from LH1, CSFT, CSKO than from G and GS. The release of individual elements in all incubation times is expressed very well by cubic polynomials. Maximum disappeared portions of individual minerals from forages are as follows: Ca 86.3% and Mg 93.2% from CSFT, Na 98.7% from GN and K > 98% from all feeds. Potassium solubility is rapid and is not affected by the incubation time.

Abstract: The aim of the study was to compare physiological statuses of stripped and not stripped tench females with ovulation induced by GnRHa or carp pituitary extract (CPE). The comparison was based on selected biochemical stress indices (cortisol, glucose), condition (TP, TGA), and cell membrane characteristics (ALT, AST, CK). In the first and in the second year, 37 and 29 tench females were monitored, respectively. No differences in the values of biochemical parameters in either period were found between the two groups of stripped female tench whose ovulation was induced by GnRHa and CPE, respectively. No significant differences in TP, TGA, ALT, AST and CK values were found between the groups of stripped and not stripped females with ovulation induced by GnRHa or CPE. Different values were found in stress indices, specifically in glucose concentrations. A significant increase (P < 0.01) in glucose concentrations was found in tench females immediately after stripping and, in not stripped females, about 48 hrs after ovulation induction. Both artificial stripping and the inability to release eggs are important stress factors for female tench.
