The aim of the research was to establish the influence of the number and height of blades of a drum mixer on the quality of the prepared mixture of concentrated feed. The research method of the drum mixer provided for the experimental determination of the coefficient of variation (unevenness) of the mixture with a three-level combination of the blades height and their number. The absence of an extremum according to the obtained data required the use of a fourth level of the number of blades. Computer processing of the results made it possible to establish a functional dependence of the influence of design factors on the quality of the mixture. The implementation of the used research methodology for the operation of the drum mixer made it possible to establish an adequate functional dependence of the influence of the number of blades and their height on the quality of the mixture. The number of blades used practically does not affect the coefficient of variation of the content of the control component. The values change less than experimental error. However, existing trends indicate a slight (about 1%) decrease in the coefficient of variation of the mixture with an increase in the number of blades from 2 to 8 pcs. For 50 kg of feed in a drum capacity of 0.26 m3, the height of the blades is about 0.15 m. The increase or decrease in the height to 0.125 m or 0.175 m affects the quality of the mixture, increasing the coefficient of variation from 20.6% to 34-50% at the proportion of the control component of 1% and the mixing time of 200 seconds.

This article presents the results of tests conducted as part of a research project with the primary objective of developing new copper alloys with limited lead content. The new group of materials were created in a production plant. As part of tests, a group of 22 alloys were selected for testing in castability, structural characteristics and hardness. Based on the test results obtained, the group of alloys under study was narrowed down to nine. The mechanical properties of these alloys were determined in static tensile tests as well as in uniaxial upsetting tests at elevated temperature, on the basis of which the group of alloys under investigation was further narrowed to three. Further studies involved technological verification of the application of these alloys under industrial conditions. These alloys were subject to numerical forging analyses, along with forging tests, under semi-industrial conditions, where the degree of filling of a die impression at a specific temperature was measured using an optic scanner. The quality of production of the obtained forgings was evaluated macroscopically with simultaneous observations of the microstructure.

AbstractIn this study, the effect of the halved dosage of RRR-d-α-tocopherol (with respect to dl-α-to-copherol acetate) in diets containing oil rich in linoleic or α-linolenic acid (soybean or linseed oil, respectively) on the quality characteristics and fatty acid (FA) profile of turkey meat was studied. The experiment was conducted using 480 one-week-old turkey hens Big 6 line reared until the 16th week of life. The hens in Groups I and II received soybean oil added to their feed mixture, in Groups III and IV linseed oil was the source of supplementary fat. Turkeys in Groups I and III received dl-α-tocopherol acetate, whereas those in Groups II and IV RRR-d-α-tocopherol. No influence of dietary manipulation was observed on the chemical composition of turkey meat. The combined effect of the type of dietary fat and vitamin E source added to the feed was assessed using the color parameters. The addition of natural vitamin E to the feed mixture with linseed oil significantly increased the proportion of PUFA in breast muscle lipids compared with the group receiving soybean oil with this form of vitamin E. The inclusion of linseed oil increased the content of α-linolenic acid and total n-3 FA concentration in both muscles, compared with the diet that contained soybean oil. This modification of FA composition led to lower n-6/n-3 ratio in both the breast and thigh muscles regardless of the dietary vitamin E source. The use of natural form of tocopherol in diets containing linseed oil may help to improve the nutritional quality of turkey meat, especially by enhancing n-3 PUFA levels with no detrimental effect of lipid addition on the chemical composition and quality of meat.

Investigation of quality variability of pig carcass was carried out on 1443 fatlings (gilts and barrows). They were progenies of 22 (Farm A) and 12 sires (Farm B), 5 breeds-crossbreds (Swedish Landrace, Large White, Duroc Hampshire, Duroc x Hampshire). Animals were fed with standardized feed mixture semi ad libitum. The quality of carcass sides was determined on the slaughter-line according to Regulation (1985). Investigation included following traits: weight of warm carcass (MTP, kg), meat in carcass sides (KMP, kg and SMP, %), total mass and ratio of leg+shoulder+loin (MFO, kg and UFO, %). Obtained results were processed using several models (Harvey, 1990) which included sire genotype, sire, sex progeny and mass of warm carcass (regression effect). All investigated traits varied under the influence of sire genotype (P<0.01) on farm B. The effect of sire genotype was significant (P<0.01) on KMP and SMP on the Farm A. All traits of carcass quality varied under the influence of sires. Gilts had higher KMP, SMP, MFO and UFO compared to male castrated heads. Difference in Total Breeding Value between best and worst boar was 10.41 (Farm A) and 11.24 index point (Farm B).

The aim of the present study was to investigate the effect of selenium yeast and phytobiotic on the storage capacity, selected quality parameters of meat and content of selenium in muscles obtained from broilers. In the experiment, 1440 male broiler chickens (Ross 308) were randomly assigned to four research groups: group received no additive (G1), group received a supplement of 0.3 mg Se (as sodium selenite)/kg of feed mixture (G2), group received 0.2 g phytobiotic and 0.3 mg Se as 0.1 g selenium yeast per 1 kg of feed mixture (G3) and group received 0.3 mg Se as 0.1 g selenium yeast per 1 kg of feed mixture (G4). Measurement of pH, determination of water retention capacity, degree of advancement of oxidative changes and selenium content in muscles were performed. Samples of chickens’ breast and thigh muscles were microbiologically analyzed. The additives significantly influenced the level of oxidation in muscles and the incorporation of selenium. The meat of chickens receiving organic selenium was characterized by significantly lower dynamics of oxidative changes. The studies carried out showed that selenium in organic form had better absorption.

The article provides information about the commodity and technological properties of fresh-dry skins obtained from silver foxes infested with the nematode Toxascaris leonina, when added to the feed of the therapeutic and preventive complex DLK. Changes in the composition of the microflora of the gastrointestinal tract were shown in helminthiasis, and a violation of the formation of hair in young silver foxes was found, which further leads to a deterioration in the quality of freshdry skin. The addition of a sulfur-containing complex to the feed mixture allows infested animals to recover their hair faster, improve their product and technological properties, and improve the quality of fresh – dry silver Fox skins of cellular breeding

The aim of the study was to establish how the addition of rapeseed oil to a processed feed mixture affects the milk produced on commercial dairy farms as well as the composition and quality of the products made from that milk. In this study, replacing grain with processed feed mixture to which 2 or 4 % rapeseed oil had been added was not found to affect milk yield or composition to any considerable extent. As a result of the test feedings, the amounts of myristic and palmitic acid in the milk fat decreased and those of stearic and unsaturated fatty acids increased. This change in fatty acid composition can be viewed as nutritionally desirable, and it also had a good effect on the consistency of butter. During the second test period (4 % rapeseed oil) the cutting firmness figures of the butter were lowest, and in sensory evaluations the butter was also found to have the best consistency. The test feeding had a slight beneficial effect on the composition of milk protein. The amount of casein nitrogen grew and that of NPN fell. However, the test feeding was not found to affect the quality of the market milk, cream, cheese or milk powder.
