Rubber mats have not yet been widely established in pig production. However, studies mostly focusing on lesions, lameness and behaviours of lactating and group-housed pregnant sows have reported favourable results. To the best of our knowledge, lesions and lameness in sows or gilts housed individually in rubber floor gestation stalls have not been previously investigated. This study was carried out on a commercial pigbreeding farm service unit during a 28-day production cycle in all seasons. Twentyeight gilts were divided into two equal groups, control and experimental groups, and observed for each cycle. The control group was housed in standard gestation stalls with concrete slatted floor, which in the experimental group was covered with an adjusted rubber mat. During each cycle, lesions were scored on days 1, 8, 15 and 28, and lameness on day 1 and upon gilt transfer from the service unit on day 29. Gilts in rubber floor stalls showed significant reduction (P<0.05) in lesions during the cooler period. Conversely, mats had no impact on lameness score in any season. No significant correlations were found between lesions and the percentage of gilts with a particular lameness score. Accordingly, rubber flooring may improve the welfare of gilts in gestation stalls through lower lesion incidence; however, ambient temperature should be taken into consideration when available.

AbstractIn the present study, postural behaviour was compared between gilts kept in service unit with different types of flooring during all seasons. The study included four 28-day production cycles and 10 gilts per cycle, equally divided into a control and an experimental group. Control gilts were housed in gestation stalls with slatted concrete floor, whereas in the experimental group the floor was covered with an adjusted rubber mat. Postural behaviour of gilts was observed 4 times per cycle for 4 hours. Study results showed that during cooler seasons, gilts in concrete stalls spent more time standing and lying sternally, whereas gilts in matted stalls were mostly lying, predominantly laterally (P<0.001 all). There were no significant between group differences according to the time the gilts spent sitting or the frequency of changing posture in any season observed. Nevertheless, experimental animals spent significantly less time changing standing to both lying positions during all seasons (P<0.01 all). In conclusion, rubber mats may improve lying comfort in gilts; however, when using rubber mats, the house thermal conditions should be taken in consideration.

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

Abstract The use of probiotics may be an effective strategy in sustainable pig production. The objective of this experiment was to examine the effects of Lactobacillus fermentum LfQi6 (LF) on sow and litter performance. First parity, gestating sows (UNL Resource Population Rep x DNA Genetics Duroc; n = 28) were allotted one of two treatment groups. Treatment groups consisted of a control group (CTL) fed a standard gestation and lactation diet for the duration of the study, while the experimental group was fed CTL supplemented with 10^10 CFU LF per day from d 80 of gestation through lactation. Individual piglet body weights (BW) were recorded weekly. LF sows tended to enter the farrowing crates lighter than the control sows (209.93 vs 200.91kg; P = 0.0794). LF sows had a smaller loin eye area when compared to CTL sows (6.24 vs 5.86 cm2; P = 0.0374) when entering the farrowing crates. However, LF sows tended to lose less loin area per day when in the crate (0.025 vs 0.012 cm2/d; P = 0.078); resulting with there being no difference in loin area when the sows left the farrowing crates. Piglet BW tended to be greater at weaning for the sows fed the LF (5.37 vs 5.66 kg, P = 0.0528). The mean piglet BW were 1.25,1.33; 2.37,2.44; 4.08,4.22; and 5.37,5.66 at d 0, 7, 14, 21; respectively for CTL and LF. Sows fed the LF had fewer pigs born alive per litter (16.09 vs 14.12; P &lt; 0.05) when compared to the sows fed the control diet. However, piglet mortality tended to be decreased for LF compared to CTL (3 vs 1.76; P = 0.0645). Results suggest that supplementation with Lactobacillus fermentum LfQi6 may provide some benefits with respect to sow and litter performance.

The article presents the results of bulls control slaughter, morphological and varietal composition of the pulp of carcasses, depending on the duration of the production cycle and the level of concentrates in the diet. In the gobies of the control group, the total duration of the production cycle was 18 months (546 days), with a specific gravity of concentrates in the rations of 40 % in the experimental group – 16 months (482 days) – 50 %. The suckling period of calves in the control group was 210 days, in the experimental group – 182 days, rearing – 186 and 165 days, respectively, intensive final fattening – 150 and 135 days. The differences obtained both in the pre-slaughter live weight and in the weight of the paired carcass were 1,9 and 3,4 kg, respectively, without a significant difference between the groups. The superiority of bulls of the experimental group over the control group was established according to the leading studied indicators of the morphological composition of carcasses, except the mass of bones, cartilage, and tendons. Differences in the mass of the pulp in favor of the calves of the experimental group were 5,1 kg, the coefficient of meat content was 0,21 units, the ratio of the edible part to the inedible part in the carcass was 0,26 units. All other things being equal, from the bulls of the experimental group, a higher mass of pulp of the highest grade was obtained by 4,9 kg or 2,2 %, of the first grade – by 6,4 kg or 1,8 %. The yield of secondgrade pulp was higher in the carcasses of gobies of the control group by an average of 6,2 kg or 4 %. Thus, both groups of bulls showed high slaughter weight and slaughter yield, with insignificant intergroup differences. However, due to the shorter duration of the production cycle of growing and fattening, it turned out to be preferable to use beef production technology from bull calves of the experimental group.

This study was conducted to investigate the effect of heat stress (i.e., elevated ambient temperature &ndash; Ta; 36 &deg;C &plusmn; 3 &deg;C) on growth performance, mortality rate, and on some haematological and biochemical parameters in different categories of gender and age of New Zealand White (NZW) rabbits. Animals were divided into two main groups (control and treatment), in each group there were 56 rabbits: adult females (n = 20), adult males (n = 4), growing females (n = 16), and growing males (n = 16). Results revealed that total and daily feed intake, feed conversion ratio, and total and daily gain in body weight for growing NZW rabbits were affected negatively by elevated Ta. Decreases in feed intake led to less protein biosyntheses and less fat deposition, which led to lower body weight gain. These observations were made in growing and adult rabbits of both genders. Analysis showed that red blood cell (RBC) counts showed alterations. Packed cell volume (PCV) (in adult females and males), white blood cell (WBC) counts (in growing females), lymphocytes (in growing males), monocytes (in growing females and adult males), basophils (in growing females and growing and adult males) were significantly (P &lt; 0.05) decreased, and total proteins (TP) (in adult females), glucose (Glu) (in adult females), and calcium (Ca<sup>2+</sup>) (in growing males and females) were significantly (P &lt; 0.01) lower in the experimental group. Furthermore, elevated Ta increased the mortality rate (MR) in both age groups. The mortality rate was 30.36% for growing and adult rabbits of the experimental group, compared with 7.14% for the control group, and was 25% for adult compared with 34.38% for growing experimental rabbits. Exposure of NZW rabbits of both ages and genders to elevated ambient temperature (36&deg;C &plusmn; 3 &deg;C), negatively affected their internal homeostasis which was reflected in their growth rate and various physiological signs.

Of all domestic animals, pigs suffer the most from deficiency of minerals. This is due to the specificity of pig production, feeding technology, retention and anatomical – physiological characteristics of pigs. In order to obtain the best qualities of pig production, it is necessary to make correction the ration for swines of various technological groups using mineral feed additives that take into consideration not only the physiological needs for minerals of the corresponding age groups and classes of swines but also the biogeochemical zone or the province where the farm is located. Also, conditions that accompany the emergence of a mineral deficit are taken into account. The development of new, eco-friendly, non-toxic means of preventing disorders of metabolism of minerals in pigs is a promising direction of veterinary medicine.The research was carried out ont the farm of the Kyiv region (northeastern biogeochemical zone). Biochemical parameters of blood were studied using biochemical analyzer «Labline-010» with standard sets of reagents. The content of chemical elements in water was investigated by the method of atomic emission spectrometry on the Optima 210 DV device.The paper presents the authors’ own research on determining the biochemical status of an organism of lactating sows in the northeastern biogeochemical zone of Ukraine at the prevention of microelementosis using new experimental eco-friendly means.The content of total protein, albumin, glucose, total calcium, inorganic phosphorus, cholesterol, bilirubin, activity of ALT, AST, AF in the blood serum of sows of the northern-eastern biogeochemical zone of Ukraine before and after the application of experimental drugs was investigated. The positive influence of prophylactic agents on the parameters of metabolism of proteins and calcium was defined.In the blood serum of the sows of the first experimental group, 28 days later, the total protein content on 5.3% lower and the total calcium concentration on 16.5% higher than the control group  of animals were found.In the blood serum of sows in the second experimental group,  28 days later, the total protein content on 8.3%  lower and the total calcium concentration on 19.9% higher than the control group of animals were found.

The aim of our research was to examine changes in the immune system of the rats influenced by the elevated ambient temperature. Male Wistar rats were divided, into 2 groups and housed at 20 ? 2?C (n=64, control group) and 35 ? 1?C (n=74, experimental group), during precise timing of 1, 4, 7, 14, 21, and 30 days. All the animals were given food and water ad libitum, and were lighted during 12 hours per day. We have measured IgG, IgG1, IgG2a, IgG2b and IgG2c. The obtained results showed significant elevation in the level of IgG after 4 and 7 days (+32%), IgG2a after 7th (+88%), 14th and 21nd day (+110%), IgG2b after 14 days (+60%) at 35 ? 1?C compared with the control group at 20 ? 2?C. IgG1 level was not affected and IgG2c showed significant decrease after 21st day at 35 ? 1?C. In conclusion, during the elevated ambient temperature the immune system is activated as one of the regulation mechanisms in homeostasis and survival of the population.

Peroxisomes which participate in 1ipid metabolism have been shown to be altered in several metabolic disorders and toxic conditions. In alcoholic liver disease, the single lesion most frequently found is lipid accumu1ation in hepatocytes. However, the mechanisms for this 1ipid accumu1ation are not clear. The occurrence of modifications of liver peroxisomes due to excess alcohol consumption has not been subjected to a controlled study. We utilized a combination of cytochemica1 and morphometrictechniques to study the size and number of liver peroxisomes in rats fed an alcohol-supplemented diet compared to those of matched-paired control animals.Male Sprague-Daw1ey rats (400-500 g) received a liquid diet. The experimental group (N = 5/group) was fed a diet containing 30% ethanol-derived calories (EDC) and the control group was fed an isocaloric diet to 30% EDC. A pair feeding procedure was employed to control for caloric intake. Small pieces of liver randomly selected, were fixed in 2.3% -glutaraldehyde in 0.1 M sodium cacodylate buffer, pH 7.2, incubated in a DAB medium and postfixed with. 2% aqueous osmium tetroxide. EM photographs were taken from sections of 3 tissue blocks from each sample (7,200X) with a Zeiss EM10-A (60 kV). With the use of a point counting method and a digital planimeter the volume density (Vv) and numerical density (Nv) were determined.

The studies reported here focus on similarities and dissimilarities between the terminal value hierarchies ( Rokeach, 1973 ) ascribed to different groups ( Schwartz & Struch, 1990 ). In Study 1, n = 65 East Germans and n = 110 West Germans mutually assess the respective ingroup and outgroup. In this intra-German comparison the West Germans, with a mean intraindividual correlation of rho = 0.609, perceive a significantly greater East-West similarity between the group-related value hierarchies than the East Germans, with a mean rho = 0.400. Study 2 gives East German subjects either a Swiss (n = 58) or Polish (n = 59) frame of reference in the comparison between the categories German and East German. Whereas the Swiss frame of reference should arouse a need for uniqueness, the Polish frame of reference should arouse a need for similarity. In accordance with expectations, the Swiss frame of reference significantly reduces the correlative similarity between German and East German from a mean rho = 0.703 in a control group (n = 59) to a mean rho = 0.518 in the experimental group. Contrary to expectations, the Polish frame of reference does not lead to an increase in perceived similarity (mean rho = 0.712).

The purpose of this study was to investigate the personality characteristics in adolescents with SLE. The research design is a case-control study by means of the Rorschach Method and the Wechsler Intelligence Scale. Study group: 30 female adolescents with lupus, 12–17 years of age. The SLE Disease Activity Index was administered during the period of psychological evaluation. Control group: 32 nonpatient adolescents were matched for age, sex, and socioeconomic level. In the Wechsler Intelligence Scale the mean IQ of the experimental group was significantly lower than that of the control group (77 and 98, respectively, p < .001). In the Rorschach, the lupus patients showed greater difficulty in interpersonal interactions, although they displayed the resources to process affect and to cope with stressful situations. A positive moderate correlation (p = .069) between the activity index of the disease and the affect constriction proportion of the Rorschach was observed: the higher the SLEDAI score, the lower the capacity to process affect. There is a negative correlation between the activity index of the disease and the IQ (p = .001): with a higher activity index of the disease, less intellectual resources are available.
