AB  - The aim of this study was to examine the effect of using tannin supplement in ration for mid-lactation dairy cows (90 +/- 17 days in milk) and the number of lactation on metabolic profile parameters values. Additionally, the effect of tannin supplementation on cows production characteristics in the 2nd lactation was evaluated. Research was conducted on 80 Holstein cows divided into two groups of 40 cows (control and experimental group) that included 16 cows in 2nd and 12 in 3rd and 4th lactation. The tannin supplement Tanimil SCC (40 g/cow/day; 40% of tannins) was added in the total mixed ration (TMR) of experimental group, while the control group of cows was fed ration without the tannin supplement. The trial lasted 60 days. Dairy cows, fed diet supplemented with tannin, had markedly lower values (P<0.05) of B-hydroxybutyrate concentration (0.79 vs. 0.96 mmol/L) and lower blood urea concentration (5.89 vs. 6.93 mmol/L). Difference in the blood glucose concentrations (3.92 vs. 3.89 mmol/L) was not significant. The lactation number had no significant effect on values of metabolic profile parameters (concentration of glucose, B-hydroxybutyrate and urea). The effect of interaction of lactation number and tannin supplement on the values of examined parameters of metabolic profile was not significant. Supplementation of tannin in the diet for cows in the second lactation, had a positive effect (P<0.05) on the milk yield (4.42%) and yield of 4% fat corrected milk (FCM, 5.24%). The use of tannin, improved concentration (3.20 vs. 3.12%) and yield (from 1.16 to 1.24 kg/day) of milk protein (P<0.05). Addition of tannin also improved concentration and yield of milk fat, as well as the concentration of lactose. The supplementation of Tanimil SCC to mid-lactation dairy cows had a positive impacts on reduction of blood content of B-hydroxybutyrate and urea, and improved productive performances of cows in the second lactation.

AB  - The aim of this study was to determine and evaluate the basic haematological parameters in conditions of natural infection of sheep with Strongyloides papillosus, as well as after the administration of antihelminthic albendazole (ABZ). Based on the intensity of infection with S. papillosus the sheep were divided into three groups: mild, moderate and high, and after that the sheep received a single dose of ABZ of 5mg/kg per body weight, per orally. Sampling of faeces and blood for parasitological and haematological assaying respectively, was performed on the 0 and the 21st day after the treatment with ABZ. The presence of parasitic infection with S. papillosus leads to a decrease of erythrocyte count, while the lowest values were established in the group with the highest intensity of parasitic infection (p ˂ 0.001). After treatment with ABZ the decrease of erythrocyte count was more prominent, which was, based on comparison with control groups C1 and C2, unequivocally established to be the consequence of treatment with ABZ. Detected values of haematocrit and erythrocyte indices indicated the presence of parasitic infection: the lowest values were established in the group with the highest intensity of parasitic infection. After treatment with ABZ haematocrit levels in control group C2 were statistically significantly lower compared to the control group C1 (p ˂ 0.001). In the presence of parasitic infection, the neutrophil and eosinophil counts increased almost linearly up to the value of 44.24±2.50% and 13.29±0.61% respectively, in the group of sheep with the highest intensity of parasitic infection (p ˂ 0.001; compared to control group C1). After treatment with ABZ the decrease of the number of these white blood cells is statistically significant (p ˂ 0.001). Bearing in mind our previous research and the connection of disbalanced redox equilibrium after the treatment with ABZ with changes, it is necessary to include antioxidative substances in the anti-parasitic treatment protocols.
AB  - Cilj ovog istraživanja bio je da se utvrde i procene osnovni hematološki parametri u uslovima prirodne infekcije ovaca sa Strongyloides papillosus, kao i nakon primene antihelmintika albendazola (ABZ). Na osnovu intenziteta infekcije sa S. papillosus ovce su podeljene u tri grupe: niski, srednji i visoki intenzitet infekcije, a zatim su ovce jednokratno dobile peroralno ABZ, u terapijskoj dozi od 5 mg/kg telesne mase. Uzorkovanje fecesa za parazitološka i za hematološka ispitivanja obavljeno je nultog i 21. dana od primene ABZ. Utvrđeno je da prisustvo parazitske infekcije sa S. papillosus dovodi do pada broja eritrocita, pri čemu su najniže vrednosti utvrđene u grupi sa najvećim intenzitetom parazitske infekcije (p ˂ 0,001). Nakon terapije sa ABZ pad broja eritrocita je izraženiji, što je nesumnjivo nastalo kao posledica terapije ABZ (na osnovu poređenja C1 i C2). Utvrđene vrednosti hematokrita i eritrocitnih indeksa su ukazivali na postojanje parazitske infekcije; najniže vrednosti su utvrđene kod grupe sa najvećim intenzitetom parazitske infekcije. Nakon terapije sa ABZ vrednosti hematokrita kod C2 bile su statistički značajno niže u odnosu na kontrolnu grupu C1 (p ˂ 0,001). U prisustvu parazitske infekcije broj neutrofila i eozinofila povećava se gotovo linearno, do vrednosti od 44,24±2,50% kod neutrofila, odnosno od 13,29±0,61% kod eozinofila u grupi ovaca sa najvećim intenzitetom parazitske infekcije (p ˂ 0,001). Nakon terapije sa ABZ broj ovih ćelija bele krvne loze smanjuje se statistički značajno (p ˂ 0,001). Imajući u vidu naša prethodna istraživanja i povezanost narušene redoks ravnoteže posle terapije sa ABZ sa promenama utvrđenim u ovom istraživanju, neophodno je u antiparazitske terapijske protokole uključiti antioksidativne supstance.

AB  - The effects of general and special biosecurity measures to prevent introduction of infectious agents in a dairy farm or its spreading from farm were analyzed in details in this paper. Investigations were conducted on five different dairy farm production with different technology and capacity using a questionnaire method (Hristov and Stanković, 2009), as well as scrutinizing their positions in relation to possible sources bio-risks from the near and far away environment. Test results showed that there are serious shortcomings on all observed farms, regarding the possibility of introduction of infectious agents in the production herd, and its possible spread to the environment. Although all fenced and a position of the most of the farms mostly favourable, there are some serious threats to the herd health and farm production, regarding open space and lack of green belt, the uncontrolled presence of wild birds and rodents in facilities and even in feed storage, as well as contact of the employees with other cows not belonging to the farm.

Iako su sve ograđene, a položaj većine ispitivanih farmi uglavnom povoljan, otvorenost prostora i nedostatak zelenog pojasa, nekontrolisano prisustvo divljih ptica i glodara u objektima za držanje krava pa čak i smeštaj hrane, kao i kontakt zaposlenih sa drugim govedima koja ne pripadaju farmi predstavljaju ozbiljnu pretnju po zdravstveno stanje zapata i proizvodnju farme.

AB  - The objective of this research was to study the effects that the extract of rhizome and root of Helleborus odorus W. et K. (Ranunculaceae) can have on modifications in the parameter values of white blood cells count and degree of phagocytosis by peritoneal macrophages and neutrophil granulocytes in Wistar rats. The trial was conducted on 28 rats divided into 4 groups with 7 animals in each group. To the control group of rats sterile physiological solution in the quantity of 0.25 mL/100 g BW was applied intramuscularly. For the purpose of monitoring the effect of the extract of rhizome and root of hellebore (HE) during a time period, the HE was applied intramuscularly to rats in a dose of 10 mg/100 g BW, while the blood samples for analysis were taken after 24h, 48h and 72h. The consequence of intramuscular application of HE was an increased count of total leukocytes in all trial groups, the most expressed leukocytosis being registered 24h after application of HE. Statistically significant higher value in the count and percent of neutrophil granulocytes in the blood was recorded 24h after treatment in relation to the control and two other trial groups (p lt 0.001), among which a statistical significance was not established. The extract of hellebore rhizome and root has led to lymphopenia, resulting in the increase of the neutrophil/limphocyte index in the trial groups 24h and 48h after treatment. The application of HE had no significant effect on the count of monocytes in treated animals. The applied extract has caused a significant increase in the degree of phagocytosis by residing peritoneal macrophages and neutrophil granulocytes in blood.
AB  - Cilj ovog rada je bio da se ispita uticaj ekstrakta rizoma i korena H. odorus W. et K. na promenu vrednosti parametara bele krvne slike i stepen fagocitoze od strane peritonealnih makrofaga i neutrofilnih granulocita kod pacova soja Wistar. Ogled je izveden na 28 pacova podeljenih u 4 grupe po 7 jedinki. Kontrolnoj grupi pacova je intramuskularno aplikovan sterilan fiziološki rastvor u količini od 0,25 ml/100 g TM. U cilju praćenja efekta ekstrakta rizoma i korena kukureka (EK) u toku vremena, pacovima je intramuskularno aplikovan EK u dozi od 10mg/100g TM, a krv za analizu je uzimana posle 24h, 48h i 72h. Intramuskularna aplikacija EK imala je za posledicu povećanje broja ukupnih leukocita u svim oglednim grupama, pri čemu je najizraženija leukocitoza registrovana 24h nakon aplikovanja EK. Statistički značajno veća vrednost broja i procenta neutrofilnih granulocita u krvi zabeležena je 24h posle tretmana u odnosu na kontrolnu i ostale dve ogledne grupe (p lt 0,001), između kojih nije utvrđena statistička značajnost. Ekstrakt rizoma i korena kukureka doveo je do nastanka limfopenije, što je imalo za posledicu povećanje neutrofilno/limfocitnog indeksa u oglednim grupama 24h i 48h nakon tretmana. Aplikacija EK nije značajno uticala na broj monocita kod tretiranih životinja. Upotrebljeni ekstrakt doveo je do značajnog povećanja stepena fagocitoze od strane rezidentnih peritonealnih makrofaga i neutrofilnih granulocita krvi.

abstract = "The objective of this research was to study the effects that the extract of rhizome and root of Helleborus odorus W. et K. (Ranunculaceae) can have on modifications in the parameter values of white blood cells count and degree of phagocytosis by peritoneal macrophages and neutrophil granulocytes in Wistar rats. The trial was conducted on 28 rats divided into 4 groups with 7 animals in each group. To the control group of rats sterile physiological solution in the quantity of 0.25 mL/100 g BW was applied intramuscularly. For the purpose of monitoring the effect of the extract of rhizome and root of hellebore (HE) during a time period, the HE was applied intramuscularly to rats in a dose of 10 mg/100 g BW, while the blood samples for analysis were taken after 24h, 48h and 72h. The consequence of intramuscular application of HE was an increased count of total leukocytes in all trial groups, the most expressed leukocytosis being registered 24h after application of HE. Statistically significant higher value in the count and percent of neutrophil granulocytes in the blood was recorded 24h after treatment in relation to the control and two other trial groups (p lt 0.001), among which a statistical significance was not established. The extract of hellebore rhizome and root has led to lymphopenia, resulting in the increase of the neutrophil/limphocyte index in the trial groups 24h and 48h after treatment. The application of HE had no significant effect on the count of monocytes in treated animals. The applied extract has caused a significant increase in the degree of phagocytosis by residing peritoneal macrophages and neutrophil granulocytes in blood., Cilj ovog rada je bio da se ispita uticaj ekstrakta rizoma i korena H. odorus W. et K. na promenu vrednosti parametara bele krvne slike i stepen fagocitoze od strane peritonealnih makrofaga i neutrofilnih granulocita kod pacova soja Wistar. Ogled je izveden na 28 pacova podeljenih u 4 grupe po 7 jedinki. Kontrolnoj grupi pacova je intramuskularno aplikovan sterilan fiziološki rastvor u količini od 0,25 ml/100 g TM. U cilju praćenja efekta ekstrakta rizoma i korena kukureka (EK) u toku vremena, pacovima je intramuskularno aplikovan EK u dozi od 10mg/100g TM, a krv za analizu je uzimana posle 24h, 48h i 72h. Intramuskularna aplikacija EK imala je za posledicu povećanje broja ukupnih leukocita u svim oglednim grupama, pri čemu je najizraženija leukocitoza registrovana 24h nakon aplikovanja EK. Statistički značajno veća vrednost broja i procenta neutrofilnih granulocita u krvi zabeležena je 24h posle tretmana u odnosu na kontrolnu i ostale dve ogledne grupe (p lt 0,001), između kojih nije utvrđena statistička značajnost. Ekstrakt rizoma i korena kukureka doveo je do nastanka limfopenije, što je imalo za posledicu povećanje neutrofilno/limfocitnog indeksa u oglednim grupama 24h i 48h nakon tretmana. Aplikacija EK nije značajno uticala na broj monocita kod tretiranih životinja. Upotrebljeni ekstrakt doveo je do značajnog povećanja stepena fagocitoze od strane rezidentnih peritonealnih makrofaga i neutrofilnih granulocita krvi.",

AB  - This paper presents the results of investigations of parameter values of the red blood cell count in Wistar rats, after intramuscular application of rhizome and root extract of Helleborus odorus W. et K (HE). The trial was conducted in experimental conditions on 49 Wistar rats divided into 7 groups with 7 animals per unit (control and six experimental groups). The control group was treated by an intramuscular injection of sterile saline (0.25 ml/100 g BM). For the purpose of determing the duration of the HE effects, the animals were injected with a dose of 10 mg/100 g BMand blood was collected by cardial taps after 24, 48 and 72 hrs. Moreover, we investigated the influence of elevated temperatures on the noted HE extract effects, 24 hrs after the application of the inactivated (56oC 30 min) or denaturized (100oC 5 min) extract, as well as the influence of dialyzed HE. The obtained results of haematological analyses have pointed out the weak hemolyses activity of the extract. In all experimental groups, the erythrocyte count was decreased, but remained within reference values. Haemoglobin concentration and haematocrit values in the experimental and the control groups of rats were decreased in comparison to the physiological values, while the applied extract did not significantly affect the examined parameters. .

AB  - During the hottest summer months in our country, conditions for thermal stress development in cows are present, especially when values of temperature and air humidity increase simultaneously. When temperature rises, cow organism becomes less efficient, due to primary non-evaporative patterns of heat release (radiation, conduction, convection), relying mostly on evaporative cooling through sweating and gasping. High relative humidity impedes evaporative cooling, so cows do not use enough body heat to prevent body temperature increase during hot and humid conditions, which are very common during summers in Serbia. Increase of ambient temperature, temperature-humidity index and rectal temperature of the cows above critical values are accompanied by decrease of dry matter intake and milk production, making dairy production less remunerative. Modifications which include shade, increase of passive ventilation and additional usage of fans and sprinklers in stables increase body heat release, decrease body temperature and support dry matter intake. New technologies, which include tunnel system of ventilation, were studied in order to evaluate cooling efficiency. Selection of cows for heat tolerance is possible, and it must be emphasized that continual selection for productive traits improvement and neglect of heat tolerance leads to increased sensitivity to heat stress. Nutritive needs of dairy cows change during heat stress demanding modifications of meal composition in order to decrease dry matter content, increase of its nutritive value, to prevent nutritive oversteps and to maintain normal function of rumen. In the future, maintenance of dairy production during hot and humid climate conditions will demand improvement of possibility of cooling, continuous improvement of meal composition, as well as genetic advances which include selection for heat tolerance and identification of genetic traits responsible for heat tolerance. .
AB  - U našoj zemlji, u toku najtoplijih letnjih meseci, postoje uslovi za razvoj termalnog stresa kod krava, naročito kod istovremenog povećanja temperature i relativne vlažnosti. Zbog primarnih neevaporativnih načina odavanja toplote (radijacija, kondukcija, konvekcija), organizam krava postaje manje efikasan sa povećanjem ambijentne temperature i oslanja se u znatnoj meri na evaporativno rashlađivanje u obliku znojenja i dahtanja. Visoka relativna vlažnost ometa evaporativno rashlađivanje, tako da za vreme toplih i vlažnih uslova, čestih u Srbiji u letnjem periodu, mlečne krave ne troše telesnu toplotu u dovoljnoj meri, da bi se sprečilo podizanje telesne temperature. Povećanje temperature sredine, indeksa temperature i vlažnosti i rektalne temperature krava iznad kritičnih granica prati smanjenje unošenja suve materije i proizvodnje mleka, čime se smanjuje rentabilnost u proizvodnji mleka. Modifikacije koje uključuju hladovinu, povećanje intenziteta prirodne ventilacije i dopunsko korišćenje mehaničkih ventilatora i prskalica u stajama povećavaju odavanje telesne toplote, snižavaju telesnu temperaturu i pospešuju unošenje suve materije. Nove tehnologije koje uključuju tunelski sistem ventilaticije su proučavane radi procene efikasnosti rashlađivanja. Selekcija krava na toplotnu toleranciju je moguća, ali treba imati u vidu da kontinuirana selekcija na poboljšanje proizvodnih osobina, zbog zanemarivanja toplotne tolerancije, dovodi do porasta osetljivosti na toplotni stres. Nutritivne potrebe krava se menjaju tokom toplotnog stresa zbog čega su potrebne izmene u sastavu obroka u pravcu smanjenja unošenja suve materije, povećanja hranljive vrednosti obroka, sprečavanja nutritivnih prekoračenja i održavanja normalne funkcije rumena. Održanje proizvodnje krava u toku toplih i vlažnih klimatskih uslova zahtevaće u budućnosti unapređenje mogućnosti rashlađenja, kontinuirani napredak u sastavljanju obroka, kao i genetska poboljšanja koja uključuju selekciju na toplotnu toleranciju i identifikaciju genetskih osobina koje povećavaju toplotnu toleranciju. .

abstract = "During the hottest summer months in our country, conditions for thermal stress development in cows are present, especially when values of temperature and air humidity increase simultaneously. When temperature rises, cow organism becomes less efficient, due to primary non-evaporative patterns of heat release (radiation, conduction, convection), relying mostly on evaporative cooling through sweating and gasping. High relative humidity impedes evaporative cooling, so cows do not use enough body heat to prevent body temperature increase during hot and humid conditions, which are very common during summers in Serbia. Increase of ambient temperature, temperature-humidity index and rectal temperature of the cows above critical values are accompanied by decrease of dry matter intake and milk production, making dairy production less remunerative. Modifications which include shade, increase of passive ventilation and additional usage of fans and sprinklers in stables increase body heat release, decrease body temperature and support dry matter intake. New technologies, which include tunnel system of ventilation, were studied in order to evaluate cooling efficiency. Selection of cows for heat tolerance is possible, and it must be emphasized that continual selection for productive traits improvement and neglect of heat tolerance leads to increased sensitivity to heat stress. Nutritive needs of dairy cows change during heat stress demanding modifications of meal composition in order to decrease dry matter content, increase of its nutritive value, to prevent nutritive oversteps and to maintain normal function of rumen. In the future, maintenance of dairy production during hot and humid climate conditions will demand improvement of possibility of cooling, continuous improvement of meal composition, as well as genetic advances which include selection for heat tolerance and identification of genetic traits responsible for heat tolerance. ., U našoj zemlji, u toku najtoplijih letnjih meseci, postoje uslovi za razvoj termalnog stresa kod krava, naročito kod istovremenog povećanja temperature i relativne vlažnosti. Zbog primarnih neevaporativnih načina odavanja toplote (radijacija, kondukcija, konvekcija), organizam krava postaje manje efikasan sa povećanjem ambijentne temperature i oslanja se u znatnoj meri na evaporativno rashlađivanje u obliku znojenja i dahtanja. Visoka relativna vlažnost ometa evaporativno rashlađivanje, tako da za vreme toplih i vlažnih uslova, čestih u Srbiji u letnjem periodu, mlečne krave ne troše telesnu toplotu u dovoljnoj meri, da bi se sprečilo podizanje telesne temperature. Povećanje temperature sredine, indeksa temperature i vlažnosti i rektalne temperature krava iznad kritičnih granica prati smanjenje unošenja suve materije i proizvodnje mleka, čime se smanjuje rentabilnost u proizvodnji mleka. Modifikacije koje uključuju hladovinu, povećanje intenziteta prirodne ventilacije i dopunsko korišćenje mehaničkih ventilatora i prskalica u stajama povećavaju odavanje telesne toplote, snižavaju telesnu temperaturu i pospešuju unošenje suve materije. Nove tehnologije koje uključuju tunelski sistem ventilaticije su proučavane radi procene efikasnosti rashlađivanja. Selekcija krava na toplotnu toleranciju je moguća, ali treba imati u vidu da kontinuirana selekcija na poboljšanje proizvodnih osobina, zbog zanemarivanja toplotne tolerancije, dovodi do porasta osetljivosti na toplotni stres. Nutritivne potrebe krava se menjaju tokom toplotnog stresa zbog čega su potrebne izmene u sastavu obroka u pravcu smanjenja unošenja suve materije, povećanja hranljive vrednosti obroka, sprečavanja nutritivnih prekoračenja i održavanja normalne funkcije rumena. Održanje proizvodnje krava u toku toplih i vlažnih klimatskih uslova zahtevaće u budućnosti unapređenje mogućnosti rashlađenja, kontinuirani napredak u sastavljanju obroka, kao i genetska poboljšanja koja uključuju selekciju na toplotnu toleranciju i identifikaciju genetskih osobina koje povećavaju toplotnu toleranciju. .",
