Clinical pattern and dynamics of some biochemical indicators were observed in six four-year lambing ewes of the Improved Wallachian breed in the course of 32-day administration of magnesite fly ash. A daily dose of the tested fly ash with the content of 305,000 mg/kg magnesium amounted to 500 mg/kg live weight of sheep. The intake of concentrate mixture with magnesium content in the test sheep decreased by a third between the 12th and 20th day, by another half between the 20th and 26th day and the intake was minimum to nil during the last seven days of the trial. The decrease in the intake of concentrate mixture was accompanied by increased water consumption and by gradual inappetence for hay. Shaped droppings started to change their consistency to slurry consistency from the 12th day of observation. Thinner to watery consistency of excrements appeared in all sheep between the 15th and 20th day and diarrheas persisted in all animals until the end of the trial. The indicators of hematological profile did not show an undoubted relationship to the administration of tested magnesium, and the variations in the particular indicators observed during the trial were within the physiological range. Serum enzymes showed a significant increase against the starting values only in the concentration of alanine aminotransferase on day 20 and day 26 (p < 0.05 and/or p < 0.001). An increase in the proteosynthetic activity of hepatocytes signalled a statistically significant increase in total proteins (p < 0.05), total immunoglobulins (p < 0.05) and an insignificant increase in albumin content. Out of the analyzed mineral elements, magnesium content showed the most significant relationship to administration of industrial pollutants as its significant increase in blood serum, urine and droppings was observable since day 20 (p < 0.05, p < 0.01 and p < 0.001, respectively). The dynamics of calcium, phosphorus, potassium, sodium, iron, copper, zinc, molybdenum, arsenic and cadmium concentrations showed different patterns in the blood serum, droppings and urine of sheep in the course of magnesite fly ash feeding, and the evaluation of interactions with magnesium requires further studies.

Sixteen head of 7 to 10 days old calves of the Black-Pied breed with clinical diagnosis of gastroenteritis acuta were examined for their clinical and laboratory findings before i. v. application of 8.4% solution of NaHCO3 and after it, using the well-known formula: live weight in kg x 0.6 x base deficit. The calves presented clinical symptoms of severe dehydration with profuse diarrhea. Dominant symptoms of the calf dehydration syndrome involved enophthalmos, lying down, lowered surface body temperature and strong exsiccosis of the organism. The values of pH, PCO2, HCO3, ABE, SBC were determined as acid-base indicators in venous blood. The most important adjustment of acid-base indicators was observed in pH, ABE and SB; their increases were statistically significant within the 3rd and/or 24th hour after intravenous application of 8.4% NaHCO3 solution at a significance level of p < 0.05 and/or p < 0.01. Buffering capacity of NaHCO3 was relatively strongly reflected in all indicators under observation when they were determined as reference values in 24 hours after application. The adjustment of acid-base indicators was accompanied by general improvement of calf health while the sucking reflex was resumed, which provided the conditions for accelerated replacement of fluids and electrolytes by i. v. as well as p. o. application forms.

A study of current resistance to antibiotics was conducted in 500 strains of Staphylococcus aureus isolated from ewes with clinical and latent mastitis, from sheep milk and products made from it (sheep lumpy cheese, bryndza cheese). A diffusion disk method was used to assay 14 kinds of antibiotics (AMP, BAC, CEF, ERY, GEN, CMP, KAN, LIN, OXA, PEN, RIF, SPI, VAN, TET) and one chemotherapeutic drug (COT). The highest resistance was observed in the cases of clinical mastitis (from 8% and 10% in COT and KAN to 68% and 69% in PEN and TET). Resistance significantly decreased in 13 kinds of antibiotics in the group of cases with latent mastitis (from 3% in SPI to 30% in PEN), it increased in KAN (13%) and COT (12%) only. Resistance also decreased in bulk samples of sheep milk; it was the highest in PEN (27%) and AMP (17%) and the lowest in CEF, RIF and SPI (5%). Sheep lumpy cheese and bryndza cheese are mostly made from unpasteurized milk. Resistance continued to decrease even in these dairy products. It ranged from 2% in CEF to 16% in OXA in sheep lumpy sugar, while it varied from 0% in SPI to 14% in TET in bryndza cheese. The results demonstrate that sheep milk and products made from it are not any important sources of antibiotic resistance of S. aureus in Central Slovakia.

A clinical picture and dynamics of metabolic indicators were examined in 40 goats suffering from iodopenia; the examinations took place in the course of potassium iodide application. Crystalline kalium iodatum was administered to all animals in barley groats at a dose of 0.5 g per animal/day within three weeks; then a three-week withdrawal followed and the treatment was repeated within the same time period. The thyroid gland consistency started to change at the end of the 3rd week of treatment when the tough elastic to tough thyroid became the soft one. The goiter started to disappear gradually from the 8th week of experiment and the physiological state of this organ was normal in most animals in the 11th week. Among the biochemical indicators, the most sensitive response to treatment was recorded in iodine and thyroxine concentrations in blood serum since their significant increase in comparison with the values before potassium iodide application was obvious on day 14 of treatment (P < 0.01). Return of total lipids and cholesterol content to the physiological limits occurred within two weeks while in glucose it was in the 7th week of treatment. A significant increase in serum immunoglobulins was recorded from day 14 to the end of experiment (P < 0.01). Among the minerals analyzed, positive responses in blood serum to potassium iodide intake were determined in the concentrations of calcium, phosphorus, copper and zinc. Application of potassium iodide to affected goats had positive effects on the dynamics of leukocytes from the end of the 2nd week (P < 0.01), of erythrocytes from the 7th week (P < 0.01), of hemoglobin and hematocrit value at the end of experiment (P < 0.05 and P < 0.01, resp.).

The objective of the paper was to assess the occurrence of congenital struma in kids in relation to the clinical and biochemical finding in their mothers. Observations involved 46 imported goats of Saanen and Alpine breeds in the course of kidding and their kids. Thyroid gland hypertrophy (39 goats) and somewhat worse or even bad state of nutrition were dominant clinical findings in pregnant goats and in goats after kidding. Abortions in the last month of pregnancy were recorded in 14 goats, and 14 goats delivered stillborn kids. Eighteen goats delivered 26 liveborn kids, but 18 out of them died within 12 to 24 hours after birth. Dead kids were hairless, they had skin edema, and very shortened thoracic as well as pelvic limbs. The thyroid gland was well visible and palpable. Surviving kids lagged behind in their growth and often suffered from bronchopneumonia as an additional disease. Iodine concentration in the blood serum of goats (5.58 +/- 2.14 mumol/l) was significantly lower (P < 0.01) in comparison with kids (133.4 +/- 15.61 mumol/l). This state was characterized by adequate T3 and T4 concentrations in the blood serum of goats (1.78 +/- 0.59 and 4.53 +/- 4.44 nmol/l, resp.) and of kids (4.66 +/- 2.26 and 182.93 +/- 2.59 nmol/l, resp.). Iodine content in the thyroid gland of the seven kids that died was 1.86 +/- 0.96 mg/kg fresh tissue. Examination of indicators of the internal environment in the blood serum showed alternate statistical differences (P < 0.01) between adult goats and their kids in erythrocyte counts, hemoglobin, hematocrit value, leucocyte counts, activities of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, concentrations of total protein, albumin, total immunoglobulins, total lipids, cholesterol, phosphorus, copper, iron and zinc, while the explicit relation to disorders of iodine metabolism and thyroid hormones was not confirmed. The average content of iodine in the examined samples of soil (14.67 mg/kg) and alfalfa hay (0.1 mg/kg) demonstrated that primary deficiency of iodine in goats was the cause of congenital struma in kids.

The objective of this study was to examine the effect of vitamin E administration on plasma levels of cortisol and lactate, and on acid base balance in transported calves. In the study, eight calves, aged approx. ten days, divided into two groups, were used. 20 mg of tocopherol-acetate per kg body weight were administered orally to each of the four experimental calves 24 hours before loading. The calves were transported by road for 3 hours. Blood samples collected before and after the transportation were examined for acid base balance, lactate, and plasma vitamin E and cortisol levels. The administration of vitamin E led to a decrease of cortisol levels in 24 hours (from 7.6 +/- 9.5 to 4.2 +/- 0.2 nmol/l) as well as to a significant increase (p < 0.05) of plasma vitamin E levels 26 h after administration (from 2.52 +/- 1.36 to 12.28 +/- 6.14 mumol/l). There was no difference between the groups in cortisol response due to transportation stress (Tab. III). The transportation caused typical stress changes in lactate levels and acid base balance (lactacidaemia and the tendency to acidosis, Tab. III, IV). There was approx. threefold increase in plasma lactate concentrations due to transportation (from 2.49 +/- 0.69 to 6.35 +/- 3.75 mmol/l). The results of the present study demonstrated metabolic changes which has been reported to be typical of mild physiological stress reaction. In the present study, vitamin E had no significant effect on plasma levels of cortisol, and lactate, and acid-base balance.

The objective of the paper was to test efficiency of feed ration enriched with calcium, phosphorus salts and fat concentrate for elimination of negative impacts of magnesite light ashes in beef bulls kept in an exposure area of magnesite works. For this purpose, 24 animals received a feed mix fortified with dicalcium phosphate at a rate of 100 g per head/day for eight months (P1 group) and another group of 24 bulls were administered a feed mix with an addition of 8% corn fat concentrate (P2 group). The other 24 animals were control (control group K). The clinical picture involved the occurrence of mild to profuse diarrheas which were alternately characteristic of all animal species in the first two months of the trial. Feed intake of the investigated groups was equal. Supplementation of feed ration with dicalcium phosphate and corn concentrate increased the weight gains of experimental animals in comparison with control bulls, the increase being 13.2 and 24.5%, resp. In comparison with the control bulls, the intake of the above supplements did not basically influence the dynamics of hematological profile indicators in the experimental bulls (Figs. 1-4). As for the parameters of hepatic profile, in the 3rd month of testing AST activity was positively influenced in both experimental groups if compared with the control group (P < 0.01), Fig. 5, and at the end of observation ALT activity in P2 group (P < 0.01), Fig. 6. Bilirubinemia dynamics did not change in the investigated groups after administration of either supplement (Fig. 9). ALP activity maintained statistically insignificantly higher values in the control animals in the second half of the trial, which demonstrated impairment of mineral metabolism in this group (Fig. 8). Significant differences in IgC levels between the control and experimental groups were confirmed in the 3rd month of the trial (P < 0.01), Fig. 12. In comparison with the control animals, the effect of dietary dicalcium phosphate supplementation in the experimental group P1 and dietary fat extract supplementation in the P2 group was observed in Ca, P and Mg concentrations to a more significant extent in the examined organs as well as in blood serum (Tabs. I-V). Except in spleen, there was a trend of higher cumulation of Ca in all the examined organs of bulls receiving dicalcium phosphate supplement. Phosphorus cumulation showed the same dependence upon dicalcium phosphate intake in the examined organs. Mg deposition in all examined organs showed minimum differences between the experimental groups and control animals.(ABSTRACT TRUNCATED AT 400 WORDS)

The objective of the paper was to investigate clinical and laboratory findings in heifers subjected to magnesite flue dust stress. A 50-day experiment was conducted in clinical conditions on five two-year heifers of the Slovak and Red Pied breeds at the live weight of 331 to 420 kg. All animals received dietary Mg from the source of magnesite flue dust at a rate of 500 mg/kg live weight. The test flue dust came from dust separation from electrostatic filters and contained these main elements: Mg (88%), Ca (1.6%), K (0.36%), Na (0.26%), Fe (1.89%), Zn (0.0026%), Cu (0.000294%) and trace amount of P. The clinical health of the animals was evaluated daily. Samples of blood, urine and dung were taken before the first administration of flue dust, on days 12, 30 and 50 of the experiment. The counts of erythrocytes, leucocytes, hemoglobin concentration and hematocrit value were determined in blood. Enzyme activities (AST, ALT, GMT), concentrations of total bilirubin, albumin, total proteins and total immunoglobulins were determined in blood serum. Contents of Mg, Ca, P, K, Na, Fe, Cu and Zn in blood serum, urine, dung and of the test pollutant were determined by atomic absorption spectrophotometry on a Perkin Elmer apparatus (model 306, 1100). Profuse diarrhea was a dominant clinical symptom in the animals which appeared in individual animals between 24th and 48th hour from the first intake of magnesite flue dust. Diarrhea lasted alternately in all heifers until day 50 of the experiment. As for the analyzed parameters of hematological profile during administration of the pollutant (Figs. 1-4), Hb and Hk (P < 0.01) increased significantly in the investigated animals on day 12 in comparison with the initial values. Out of the enzymes, AST and ALT activities showed most readily the feeding of magnesite flue dust (r = 0.99 and r = 0.92, resp.), Figs. 5 and 6. Correlation relationships between magnesite pollutant administration and bilirubinemia dynamics during the experiment indicated the correlation r = 0.53 (Fig. 8), r = 0.36 (Fig. 9) for total proteins, r = 0.75 (Fig. 10) for albumin and r = 0.93 (Fig. 11) for total immunoglobulins. In comparison with the initial values, Mg concentrations in blood serum and dung significantly increased from day 12 of experiment (P < 0.01 - Fig. 13) and in urine from day 30 (P < 0.05).(ABSTRACT TRUNCATED AT 400 WORDS)

The objective of the study was to test the effectiveness of Zn, Se and Cu supplementation through reticulum-rumen pellets and its effects on the rate of cellular and humoral reactions in sheep. An experiment included 12 lambing ewes of the Merino breed at the age of two years. Zn-containing pellets were applied via rumen to three lambing ewes at the end of November, Se pellets were applied to other three lambing ewes Cu pellets to other three ewes. Three lambing ewes were control. Blood samples were taken from the v. jugularis from all the investigated ewes before bolus administration, in month 1, 2, 3, 4, 6 and 7 after application. Zn, Se and Cu concentrations in the blood serum were determined by atomic absorption spectrophotometry. Immune reactions were evaluated from the concentrations of serum immunoglobulins (IgC), albumin (ALB), total proteins (TP), from phagocytic activity (PA), phagocytic index (PI), migration-inhibitory test (MIT) and determination of tetrazolium-reductase activity of phagocytes (INT-test). In comparison with the starting values, the highest increase in zincemia (80%) was recorded in the lambing ewes administered zinc boluses as soon as in the 1st month after administration. A significant difference in Zn concentrations between the zinc-pellet group and the control animals was observed in the 1st month after administration (P < 0.01). An increase in Se concentrations in the blood serum was observed in the lambing ewes administered selenium boluses in the 1st month after administration. Se content in the blood serum of the given group of ewes was highest at the end of observation (2.72 +/- 0.29 mumol/l). A statistically significant difference in Se content between the group of selenium-bolus ewes and the control ewes was confirmed at a significance level P < 0.05 in the 1st and 2nd month of the experiment. Cu concentrations in the blood serum in the Cu-bolus ewes increased in the 1st month if compared with the starting values. The highest Cu concentration in the blood serum was recorded in the given group within month 4 to 7 of the experiment (16.53 +/- 2.72, or 21.23 +/- 4.40 mumol/l). There were significant differences in cupremia between the Cu-pellet group of ewes and the control animals (P < 0.05). In comparison with the starting values, the highest increase in TP concentrations were determined in the Cu-pellet ewes in the 4th, 6th, and 7th months. Albuminemia dynamics in the experimental animals and in the control group did not vary significantly.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of an administration of the Zindep inj. preparation (Biotika) were evaluated in pregnant dairy cows as exerted on specific weight, total protein (TP) content, total immunoglobulin (IgC) and albumin (ALB) contents in colostrum. These parameters were also followed: calf's health, live weight, leucocyte (Lc) counts, T-lymphocyte (T-Ly) counts, contents of TPs, IgCs and ALBs in the blood serum of calves. Zinc concentrations were determined in colostrum, milk and calf blood serum. Our observations included 16 dairy cows in the seventh month of pregnancy in the second lactation and their calves in the winter feeding season. Eight experimental dairy cows were treated with the Zindep preparation in form of an injection to the neck muscles at a dose of 3 mg Zn/kg live weight in the mid-seventh month of pregnancy. Blood samples were taken from v. jugularis from all calves before their first drinking, on days 5, 15 and 30 of age. Colostrum, and/or milk samples were obtained by drawing of the colostrum or milk from the udder quarters within 60 minutes after parturition, on days 5 and 15 of lactation. Zn levels at birth were 16.48 +/- 2.67 mumol/l in experimental calves and 13.84 +/- 3.19 mumol/l in control calves. Zincaemia decreased slightly in both groups on days 5 and 15 of age, but it was insignificantly higher in calves coming from Zindep-treated dairy cows. Zn levels in the blood serum on the 30th day of age were 18.45 +/- 2.44 mumol/l in experimental animals and 15.73 +/- 3.11 mumol/l in control animals. Zn content in the colostrum of experimental cows was 2.40 +/- 0.42 mg/l and in the control it was 1088 +/- 0.52 mg/l (P < 0.05). On day 5 of lactation, Zn amounts in the milk of experimental dairy cows decreased to 0.95 +/- 0.12 mg/l and to 0.76 +/- 0.10 mg/l in the control (P < 0.01). Zn levels in the milk of experimental cows on day 15 of lactation were 0.95 +/- 0.13 mg/l and in the milk of control group they were 0.82 +/- 0.14 mg/l. Colostrum specific weight from zinc-treated cows was 1,067.86 +/- 0.75 g/cm3 and 1,056.8 +/- 13.53 g/cm3 in the control. TP and IgC concentrations were 137.81 +/- 38.11 g/l and 110.13 +/- 29.91 U ZST, respectively, in the colostrum of experimental group, and 105.98 +/- 32.02 g/l and 85.53 +/- 25.42 U ZST, resp., in control animals.(ABSTRACT TRUNCATED AT 400 WORDS)
