Possibility of reduction of protein level in feed mixtures of similar content of amino acids digestible in the small intestine and its influence on fattener’s performance and nitrogen retention were determined. Thirty pigs (35 kg) were divided into 3 groups. The control animals were fed with diets with crude protein level suggested by polish pig feeding standards (Normy żywienia... 1993) – 17% in grower and 15% in finisher diet. In the experimental groups (I and II) the protein level was reduced about 10 or 20% respectively. No significant effect on feed intake, weight gains and feed utilization was found. The animals from the both experimental group utilized less crude protein (P=0.001) than in Control group. The significant (P=0.001) reduction in nitrogen excreted in urine and total N-excretion in both group with reduced protein level in feed mixtures, were observed. Nitrogen retention in g/day was higher for group I compared to other groups and N-retention : N intake were significantly higher (P<0.05) in both experimental groups. The reduction of crude protein level in the experimental diets did not affect slaughter performance but in group II the tendency to increase (P=0.064) in back fat thickness and decrease meat content in carcass, were observed. The results suggest that lowering the protein level in diets for high-meat crossbred pigs (Polish Large White × Polish Landrace) × (Hampshire × Pietrain) from 170 and 150 g kg⁻¹ to 136 g and 115 g kg⁻¹ in grower and finisher diets, respectively, but supplemented with synthetic amino acids, did not impact negatively production results of fatteners, but decreased nitrogen emission to the environment and cost of feed.

The experimental group consisted of 57 young Holstein bulls kept in the Czech Republic; 35 bulls were tethered and 22 bulls were loose housed. The aim of the study was to analyse and compare the effect of different housing systems on feedlot performance, carcass value and meat quality and their mutual relationship. The overall average values were as follows: feedlot performance parameters live weight at slaughter 434.3 kg, age at slaughter 455.8 days, total weight gain 319.3 kg, duration of fattening 342.1 days, daily weight gain 941 g; carcass value parameters dressing percentage 51.0%, net daily weight gain 482 g, weight and proportion of kidney fat 3.9 kg, 1.8% resp., weight and proportion of fat trim 2.2 kg and 2.0% resp.; meat quality parameters dry matter, fat and collagen content in muscle 23.8, 1.46 and 1.13% resp., pH24 6.08, drip loss 0.849% and remission (525 nm) 6.4%.

The aim of the research paper was to monitor and evaluate the effect of different cage area on live weight and carcass parameters of hybrid combination Ross 308 cocks and hens in 35 days feeding period. The experiment was performed in experimental practice of Department of Poultry Science and Small Animal Husbandry of Slovak Agricultural University Broiler chickens were kept in a three-deck cage system. Every cage had breadth 4320 cm2 (90 cm length, 48 cm width and 40 cm depth). One day chickens were randomly divided into three groups: The control group with 0.036 m2 of provided area for one chicken, the 1st experimental group with 0.0432 m2 of provided area for one chicken and the 2nd experimental group with 0.054 m2 of provided area for one chicken. The live weight of broiler chickens has been weighted in weekly periods at 1, 7, 14, 21, 28 and 35 days of age. Carcass parameters (share of breast from carcass, share of thighs from carcass and carcass value) have been specified in 6 chickens (nearby average live weight) from each group after the end of the experiment. At the end of the feeding period at the age of 35 days we noticed the similar tendency in live weight in cocks as well as in hens. We found out the highest average live weight in the 2nd experimental group with 0.054 m2 of provided area for one chicken (1677.67 g in cocks and 1540.42 g in hens) and the lowest average live weight in the control group with 0.036 m2 of provided area for one chicken (1488.83 g in cocks and 1402.25 g in hens). In carcass parameters of cocks we found out the highest average values of share of breast from carcass (28.38%) and carcass value (74.48%) in the control group with 0.036 m2 of provided area for one chicken and the lowest average values of these parameters in the 2nd experimental group with 0.054 m2 of provided area for one chicken. Only in the share of thighs from carcass we found out the same tendency as in the live weight. We observed the highest average values of share of breast from carcass (30.95%) in hens in the 2nd experimental group with 0.054 m2 of provided area for one chicken and share of thighs from carcass (33.62%) in hens in the 1st experimental group with 0.0432 m2 of provided area for one chicken and carcass value (74.64%) in hens in the control group with 0.036 m2 of provided area for one chicken.
