Abomasal Displacement

Abomasal displacement is one of the most important disorders of the digestive tract in high-yield dairy cows. The etiology and pathogenesis of its occurrence has not been fully clarified to this day. The work examines calcaemia and phosphataemia in cows during the antepartal and postpartal periods and their connection with the incidence of abomasal displacement. The experiment covered 30 cows in advanced stages of gravidity. Blood samples were taken two weeks before expected parturition and two weeks after calving. In all blood samples (taken antepartal and postpartal), concentrations of calcium and an organic phosphorus were determined using a commercial test package (Bio-Merieux). Following parturition, left displacement of the abomasums was established in seven (23.33 %) of the 30 cows covered by the experiment (experimental group). The remaining 23 cows in the experiment were clinically healthy, they were placed in a group and represented control animals. The average value of calcaemia for the control group of cows during the antepartal period was 2.72?0.25 mmol/l, and of phosphataemia 2.04?0.25 mmol/l. In the same cows postpartum, average calcaemia values were 2.46?0.22 mmol/l and phosphataemia 1.85?0.29 mmol/l. The average antepartal value for calcaemia in the experimental group of cows was 2.51?0.25 mmol/l, and for phosphataemia 1.73? 0.22 mmol/l. The average values for this group of cows postpartally was 2.13?0.31 mmol/l for calcaemia and 1.43?0.24 mmol/l for phosphataemia. The differences between the concentration values for calcium and phosphorus obtained postpartally between the experimental and control groups were statistically significant. .

Over Time

Since the occurrence of swine salmonellosis has increased over time and control strategies other than biosecurity are highly recommended, the present study aimed to evaluate the efficacy of vaccination with Salmonella Choleraesuis and Salmonella Typhimurium bacterins in pigs. Two experimental groups were formed: G1, animals immunized with two doses of a commercial vaccine (n = 20); G2, control group (n = 20). After vaccination, all pigs were orally challenged (D0) with 108 CFU of Salmonella Typhimurium and evaluated for 40 days. Every 10 days after D0, five piglets from each experimental group were euthanized and submitted to the necroscopic examination, when organ samples were collected. Blood samples and rectal swabs were collected before the first dose of the vaccine (D−42), before the second dose (D−21), before the challenge (D0), and thereafter, every three days until D39. Blood count, serum IgG measurement by ELISA, and the excretion of Salmonella Typhimurium in feces were evaluated. While the results from blood count and serum IgG concentration did not differ, the detection and excretion of Salmonella between G1 and G2 differed (p < 0.05). Therefore, it was observed that this vaccine partially protected the animals against experimental infection with Salmonella Typhimurium, reducing the excretion of bacteria in feces.

This study was intended as a contribution to the argument about possible suffering of animals used for demonstrative purposes during teaching at universities. Pharmacology lectures at the University of Veterinary and Pharmaceutical Sciences Brno, Czech Republic were selected for this experiment. The study focused on stress assessment using haematological and biochemical indices. Blood samples were drawn from 20 rabbits (Oryctolagus cuniculus f. domesticus L.) 10 days after arrival at the institute (before the first practical lesson), and then in the 7th and 12th weeks of the semester with practical lessons. The haematological and biochemical indices were compared between the experimental group (n = 10) used for practical demonstrations and the control group (n = 10) which was kept in its hutch. Practical lessons included manipulation with rabbits, health examination, topical or total application and observation of the drugs’ effects. All the acts were carried out by students. Significant changes were detected in some of haematological (erythrocytes, haemoglobin, haematocrit) and biochemical (glucose, total protein, enzymes aspartate aminotransferase and lactate dehydrogenase) variables compared to the control group. The values obtained from the last blood sampling indicate a possible habituation process in the experimental group between the 8th and 12th week. The results were compared between the experimental and control group and also with the results of other studies with different stressors. In conclusion, the stress the rabbits used for teaching purposes at universities are exposed to, is tolerable.

New data were obtained when studying the effect of intensive dirofilariоsis invasion on the morphological composition of the blood corpus of infected dogs. Hematological studies were performed on 20 dogs infected intensively with microfilaria. Blood from dogs was taken from a forearm vein in test tubes with an anticoagulant. For research, 2 groups were formed: experimental and control. The experimental group (n=10) consisted of dogs that had microfilaria dirofilariasis in blood samples. The control group of dogs (n=10) was formed from agelminthous animals, in the blood of which there were no nematode microfilaria. Results. With intensive invasion of dirofilariоsis in blood samples of dogs, a decrease in the number of erythrocytes is observed by 3.03х1012/l, a decrease in hemoglobin concentration by 70.68 g/l. At the same time, the number of leukocytes in the hematological profile of experienced dogs increased by 14.68х109/l, and that of eosinophils by 497.44%, which indicates profound pathophysiological changes in the hematocrit. Conclusion With a high intensity of dirofilariasis in dogs, erythropenia, hypohemoglobinemia, leukocytosis, and eosinophilia appear strongly on the background of control.

<p>We studied the influence of a different level of a calcium and phosphorus in mixed fodders on morphological and biochemical indexes of a blood of Japanese quail. We selected 240 quails, which were divided into 6 equal groups - control and 5 experimental. Experimental quails were contained in six-fodders cell battery, each cell was 60x40x20 cm and contained of 20 birds (15 females and 5 males). At the beginning of the experiment the experimental quails had similar body weight indicators that were the same in the end of our research. When we fed quails with different levels of calcium and phosphorus wew registered that calcium, magnesium, total protein and alkaline phosphatase activity in their blood was within physiological norm. We identified no significant differences in these indicators. It should be noted that the highest content of phosphorus in the quail blood was observed in female birds of 6th experimental group, which exceeded by 23.1% the values in quails of control group with calcium content of 4.0% and phosphorus of 1.4% (P &lt;0.05). The introduction of different level of a calcium and phosphorus were not significantly affect the blood erythrocytes, leukocytes, and hemoglobin. The ratio of segmented rods, eosinophils, lymphocytes and monocytes in the blood of experimental birds was within the physiological norm of fluctutations. In content, there was a slight deviation (within 1%) was not statistically significant in the blood of the bird experimental and control groups, eosinophils and monocytes. The lymphocyte content was below 8.3% in the blood of all experimental bird groups. It is revealed that a level of a calcium of 4.0 % and phosphorus of 0.8, 1,1, and 1,4 % in rations of quails, promotes rising of a calcium level in skeleton of female quails and does not influence significantly the morphological and biochemical blood indices.</p>

The study aimed to investigate the effects of teat disinfection (dipping treatment) after milking on hygienic quality of row milk. The research was conducted on the farm with 30 Holstein-Friesian dairy cows. Animals were kept in a tied housing system. Milking is done by a bucket milking units using vacuum line. The research was carried out during the period of 2 months from 26.11.2012 till 25.01.2013. Results showed that milk immediately after leaving the udder was minimally contaminated with microorganisms (average of both groups with 8,933 CFU/ml). Experimental group had an average 2.668 (133,000 SCC/ml) and control group 3.524 (about 257,000 SCC/ml) (p<0.05). The average value of CFU in experimental group was 5,816 (729,000 CFU/ml) and in the control 5.833 (805,000 CFU/ml), (p<0.05). During the study period, the average value of SCC in the experimental group decreased to 2.67 (133.020/ml) and the average value of CFU to 5.82 (729.064/ml), (p<0.05). Treatment of teat dipping after milking is justifiable and has positive impact on row milk quality.

The population of this study was the students of SMA Negeri 2 Medan. There were sixty students taken as the sample of the research. This study was conducted with two randomized groups namely experimental and control group. The experimental group was taught by applying POSSE strategy while control group was taught without applying POSSE strategy. The instrument of collecting the data was multiple choice test which consists of 40 items. To obtain the reliability of the test, the researcher used Kuder-Richardson (KR-21). The calculation shows the reliability was 0.81(high). The data were analyzed by using t-test. The calculation shows that t-observed (4.76) is higher than t-table (2.00) at the level of significance (α) 0.05 with the degree of freedom (df) 58. Therefore, the null hypothesis (Ho) is rejected and alternative hypothesis (Ha) is accepted. It means that there was a significant effect of applying POSSE strategy on the students’ reading comprehension. Keywords: POSSE Strategy, Reading Comprehension.
