Abstract
The aim of this paper was to examine the biochemical and haemological parameters of blood as well as the quality of breast meat of 45 pheasants. The pheasants were divided into three groups ...and fed by mixtures with the organic selenium supplementation in concentrations of 0.2 mg/kg (I group) and 0.3 mg/kg (II group)and with mixture without selenium in a control group (K). After 60 days of the experiment duration it was determined that the average values of selenium content in the breast meat in blood serum of II group pheasants which were fed with 0.3 mg/kg of organic selenium were significantly higher (p>0.05) in comparison to the same parameters of pheasants of the control K group. The pheasants of II group also had better sensory traits of meat and they achieved the highest difference of the sum of the ranks of the meat acceptability. The difference was by 15 points higher than in the control K group and 7 points higher than in meat of the pheasants I group fed with 0.2 mg/kg of selenium. Adding of organic selenium in the food of II group pheasants (0.3 mg/kg) had a positive effect on increasing the water retention capacity in breast meat by 0.75% compared to the control group, namely by 0.58% in comparison to I group. Average values of chemical parameters of meat (pH, water, fat, proteins and ash content), haematological parameters of pheasants blood (number of erythrocytes, leucocytes and platelets, haemoglobin and haematocrit values) and biochemical parameters of blood serum ( glucose, enzymes AST and ALT), total protein concentration, total cholesterol albumin, triglycerides, Ca, K and Na) were within the limits of reference values for pheasants and very uniform values without significant differences among examined groups.
The effects of the use of fish meal in the nutrition of weaning piglets were
observed. The trial included 80 weaned piglets of the same genotype (Large
White x Danish Landrace) distributed in two ...feeding treatments. In the first
period of the experiment, animals were fed during 10 feeding days, with a
prestarter mixture containing 21.1/20.8% of the crude protein. The second
period lasted for 25 days and piglets were fed with mixture containing also
21.0/21.1% of the crude protein. And in the final period of the experiment,
which lasted 22 feeding days, the meals were formulated to contain
19.5/19.9% of the crude protein. The control group was fed with standard
farm mixtures, while the trial group were fed with mixtures containing
4/3/2% of fish meal. The obtained results showed that the use of fish meal
resulted in better average daily gain and feed conversion in starter period
(27-51 day).
The aim of this study was to investigate the effects of the use of soybean molasses in the nutrition of lactating cows on their performance and some blood and rumen content parameters. Treatments ...included isoenergetic and isoprotein rations: total mixed ration (TMR) which included 1 kg of soybean molasses and TMR without soybean molasses. The use of soybean molasses in TMR for lactating cows increased yield of 4 % FCM (5.03 %). There was no difference in milk fat content and yield between treatments. The use of soybean molasses increased the concentration (3.45 vs 3.32 %) and yield (from 0.81 to 0.88 kg/day) of milk protein. Improved utilization of consumed ration dry matter (DM), energy and crude protein by 4.60, 4.81 and 7.82 %, respectively, was confirmed. There was no significant effect of including soybean molasses in TMR on ruminal pH value, number and structure of protozoa population nor on their motility. Soybean molasses had a positive effect on decrease of the urea blood concentration (5.45 vs 6.30 mmol/L) while no significant effects were observed for the concentrations of glucose, Ca and P in blood. Results of this study indicate that soybean molasses, as a source of readily available energy, can be used successfully in rations for lactating cows.
The synchronization of business cycles represents one of the conditions that
countries have to fulfil to become part of an optimum currency area, as well
as a condition for the efficient ...implementation of a common economic policy
in these countries. This paper examines the extent to which Serbia and its
neighbouring countries fulfil these conditions, taking the euro area as an
optimum currency area. By applying the Hodrick-Prescott and the band-pass
filters, as well as the Pearson correlation coefficient and the Spearman rank
correlation coefficient, this paper examines the synchronization of business
cycles in these countries. Taking Serbia as an example, the influence of the
foreign trade volume between two countries on the similarity of their
business cycles is tested. The results show a lower harmonization of business
cycles in Serbia with those in the euro area, when compared with the selected
neighbouring countries, and do not confirm the thesis on the influence of the
foreign trade volume on the harmonization of business cycles.
The effects of the use of antibiotics and garlic powder in the nutrition of
weaning piglets were compared. The trial included 120 weaned piglets of the
same genotype (Large White) distributed in ...three feeding treatments. In the
first study period (day 27-56), a feed mixture with 20% protein was used,
while in the second period (day 57-84), a mixture with 18% protein. The
control group was fed with mixtures containing antibiotics in the amount of
0.2%, while the two experimental groups were fed with mixtures containing
fermented garlic powder (FGP) in the concentration of 0.05% and 0.2%. The
obtained results showed that the use of FGP, instead of antibiotics,
resulted in better gain in second trial group, and also better feed
conversion ratio, in both trial groups by 3.84% and 6.93% respectively,
during the entire research period.
In this article, we explored the nature of the dynamics and behavior of inflation in the case of the Western Balkans. The inflation rate, according to the test results, in most of the countries can ...be modeled as a stationary process. The paper applied the test of linearity, and then depending on the results, the battery of linear and nonlinear unit root tests. In particular, they consider structural breaks and asymmetric adjustment in order to obtain robust results. The results of the centered calibration in one case suggest potential unstationary inflation.
