AB  - The aim of this study was to determine the influence of an energy supplement on the basis of propylene glycol on the values of metabolic profile parameters in periparturient cows. Fifteen days before calving, 40 cows were selected and divided into two groups: control (n=20) and experimental (n=20). From day 15 before to day 30 after calving, the experimental group of cows received an energy supplement based on propyleneglycol added in food ('OSIMOL', Veyx-Pharma GmbH, Germany). Blood samples were taken 15 days before and 10 days after calving. Concentrations of glucose and betahydroxybutyric acid (BHBA) were determined immediately after blood was taken. Concentrations of total protein, albumin, urea and total bilirubin were determined in the blood serum. There was no significant difference in the average values of the measured parameters between the control and the experimental group of cows. After parturition glycemia in cows of the control group was lower than physiologically acceptable (x=1.93±0.43 mmol/L), and glucose in cows of the experimental group was at the upper physiological limit (x=3.13±0.33 mmol/L) and signicantly higher (p lt 0.001) than in the control group. The concentration of BHBA in cows that received the energy supplement ('OSIMOL') was 0.40±0.12 mmol/L, while in the control group of cows it was significantly higher (p lt 0.001) and stood at 0.88 ±0.39 mmol/L. Furthermore, the concentration of total bilirubin in the cows of the experimental group was within the physiological range (x = 4.09± 1.42 μmol/L), while in the cows of the control group it was significantly higher (p lt 0.05) and stood at 10.19±5.16 μmol/l.
AB  - Cilj istraživanja izloženog u ovom radu je bio da se utvrdi uticaj energetskog dodatka na bazi propilen-glikola na vrednosti parametara metaboličkog profila krava u peripartalnom periodu. Petnaest dana pre očekivanog teljenja odabrano je 40 krava, koje su podeljene u dve grupe: kontrolnu (n=20) i oglednu (n=20). Kravama u oglednoj grupi u periodu od 15 dana pre do 30 dana posle teljenja u hranu je dodavan preparat na bazi propilen-glikola ('OSIMOL', Veyx-Pharma GmbH, Nemačka) u dnevnoj količini od 200 grama. Uzorci krvi su uzeti 15 dana pre i 10 dana nakon teljenja. Neposredno nakon vađenja krvi, u uzorcima pune krvi, određivana je koncentracija glukoze i betahidroksibuterne kiseline (BHBA). U uzorcima krvnog seruma određivana je koncentracija ukupnih proteina, albumina, ureje i ukupnog bilirubina. U antepartalnom periodu, kod krava kontrolne i ogledne grupe, nisu ustanovljene značajne razlike između prosečnih vrednosti ispitivanih parametara metaboličkog profila. Posle partusa kod krava kontrolne grupe koncentracija glukoze je bila niža od fiziološki prihvatljive (x=1,93±0,43 mmol/l), dok je kod krava ogledne grupe glikemija bila na gornjoj fiziološkoj granici (x=3,13±0,33 mmol/l) i statistički značajno viša nego kod kontrolne grupe (p lt 0,001). Koncentracija BHBA kod krava koje su dobijale energetski dodatak ('OSIMOL') iznosila je 0,40±0,12 mmol/l, dok je kod krava kontrolne grupe bila značajno veća (p lt 0,001) i prosečno iznosila 0,88±0,39 mmol/l. Osim toga, kod krava ogledne grupe koncentracija ukupnog bilirubina je bila u granicama fizioloških vrednosti (x= 4,09 ± 1,42 μmol/l), dok je kod krava kontrolne grupe ta vrednost bila značajno veća (p lt 0,05) i iznosila je 10,19±5,16 μmol/l.

AB  - In last several years, rapid progress on the field of genetics in high producing dairy cows around the world was done. On the contrary, reproductive efficiency has suffered a dramatic decrease since the mid 1980s. The reasons for the decline in fertility are multifactorial and cannot be solely attributed to an increase in milk production. On high productive dairy farms, during all year round it can be seen that acting of bioclimatic factors leads to individual and herd disorders, by acting on health and reproductive parameters, accordingly lead to temporary infertility and lower conception. Dysfunction of ovaries, subclinic cases of endometritis, disorders in reproduction cycle, disorders in ovulation and repeated heats have been recorded mostly during summer. Longer service period was notices as well as increased insemination index and lower fertility during summer time (June, July and August). Heat stress when temperature exceed 27°C disturbs mechanisms of heath and reproduction control and lead to lower milk production and reproduction in high productive dairy farms. During this period influence of bioclimatic factors can easily be seen and leads to lower fertility in both systems of husbandry (free or tied). In our paper we have monitored and analyzed fertility in total of 5272 dairy cows as well as influence of bioclimatic factors on fertility during summer time.

Postoji veliki broj razloga koji dovode do ovog negativnog trenda, a koji nisu jedino u vezi sa povećanjem proizvodnje mleka. Na farmama visoko mlečnih krava, u svim periodima godine, uočava se da delovanje bioklimatskih faktora dovodi do poremećaja kako individualno tako i stada, delovanjem na zdravstvene i reprodukcione parametre, odnosno da izazivaju privremeni sterilitet i značajno smanjuju plodnost krava. Pojave disfunkcije jajnika, subklinički endometritisi, poremećaji ciklusa, ovulacije i povađanja najviše su primećene u toku leta. Uočeno je da je servis period visoko mlečnih krava produžen, indeks osemenjavanja povećan, a steonost značajno smanjena u letnjim mesecima, junu, julu i avgustu.

Pathologic puerperium in the first 9 and especially in following 12 days or in the first 3 weeks after calving (because of retained placentas or puerperal infection) leads to extended service period and increased insemination index.

AB  - Valid indicators of the energy status of cows are the body condition, parameters of the metabolic profile, hormonal status, and organic components of milk. The energy status of cows of the Holstein-Friesian breed from four farms was estimated on the grounds of urea, protein and fat concentration in milk. Investigations covered 62 samples of milk (11 from farm A, 16 from farm B, 15 from farm C, and 20 from farm D). All cows were in the first stage of lactation and fed rations recommended for that category of animal. The average fat concentration in all milk samples was 23±13 g/l, the average protein concentration was 29±3 g/l, while the average urea concentration was 4.6±1.3 mmol/l. It could be concluded on the basis of the value for the milk fat concentration alone that a decreased milk fat syndrome was present. In addition, graphic presentations are given for the relation between urea concentration and protein concentration, as well as protein and fat concentrations in the individual milk samples. Such an analysis provided a more detailed picture of the energy status of the examined cows. It was established that cows on farm A had a deficiency of energy and protein, and cows on farms B and C a deficiency of energy with a relative surplus of proteins. It was established that cows from farm D had a deficiency of energy, and there was an equal number of cows with a deficiency and with a relative surplus of proteins. The obtained results provide grounds for making recommendations for correcting the feed rations and improving the health of the cows. It stems from the obtained results that the determination of urea, fat and protein concentrations in milk is a reliable indicator of the energy status of cows, that it is rational and financially acceptable for every producer, regardless of whether it is implemented in small or large cattle farms. The diagnostic procedures used so far have been implemented in a limited form in daily practice because of insufficient reliability (evaluation of body condition) or lack of economic feasibility (metabolic profile and hormonal status of cows).
AB  - Validni pokazatelji energetskog statusa krava su telesna kondicija, parametri metaboličkog profila, hormonalni status i organski sastojci mleka.

abstract = "Valid indicators of the energy status of cows are the body condition, parameters of the metabolic profile, hormonal status, and organic components of milk. The energy status of cows of the Holstein-Friesian breed from four farms was estimated on the grounds of urea, protein and fat concentration in milk. Investigations covered 62 samples of milk (11 from farm A, 16 from farm B, 15 from farm C, and 20 from farm D). All cows were in the first stage of lactation and fed rations recommended for that category of animal. The average fat concentration in all milk samples was 23±13 g/l, the average protein concentration was 29±3 g/l, while the average urea concentration was 4.6±1.3 mmol/l. It could be concluded on the basis of the value for the milk fat concentration alone that a decreased milk fat syndrome was present. In addition, graphic presentations are given for the relation between urea concentration and protein concentration, as well as protein and fat concentrations in the individual milk samples. Such an analysis provided a more detailed picture of the energy status of the examined cows. It was established that cows on farm A had a deficiency of energy and protein, and cows on farms B and C a deficiency of energy with a relative surplus of proteins. It was established that cows from farm D had a deficiency of energy, and there was an equal number of cows with a deficiency and with a relative surplus of proteins. The obtained results provide grounds for making recommendations for correcting the feed rations and improving the health of the cows. It stems from the obtained results that the determination of urea, fat and protein concentrations in milk is a reliable indicator of the energy status of cows, that it is rational and financially acceptable for every producer, regardless of whether it is implemented in small or large cattle farms. The diagnostic procedures used so far have been implemented in a limited form in daily practice because of insufficient reliability (evaluation of body condition) or lack of economic feasibility (metabolic profile and hormonal status of cows)., Validni pokazatelji energetskog statusa krava su telesna kondicija, parametri metaboličkog profila, hormonalni status i organski sastojci mleka.

AB  - It is generally known that health and reproductive ability of cows is influenced by both internal and external factors. The most significant internal factors are hereditary factors and the neuroendocrine system, while such significant external factors are nutrition, the effect of climate, housing and management conditions, conditions of zoohygiene, organization of reproduction, but primarily nutrition. Following reproductive disorders, all linked to deficient nutrition, are diagnosed on a daily basis on dairy farms: abortions, lack of estrus, endometritis, and pathological puerperium. Inadequate nutrition can also be manifested as reduced fertility, before the onset of other evident clinical symptoms appears. Data indicates that under certain conditions reproductive performance could be improved by supplementing diets with beta carotene or injections therefore, while supplementing nutrition with vitamins A and E decreased reproductive disorders, prevented retained placenta (RP), and improved cow fertility. Peak of lactation is an especially critical period for dairy cows since it coincides with a new pregnancy and higher vitamin and mineral requirements. Vitamins are especially significant as regulators of catalysis in the body. In relation to reproduction, the most significant are vitamin A and β-carotene, which play a specific role in the structure of the microsomal membrane in the bovine corpus luteum by guarding this membrane, while in the cytosol they are linked to plasma lipoproteins. All vitamins (in conjunction with minerals) are significant, due to their role in cell metabolism. This investigation was undertaken to determine the extent to which parenteral administration of AD3E vitamins could prevent their deficiency in diets, and how, in cases when administered, they prevented reproductive disorders.
AB  - Dobro je poznato da na zdravlje i reproduktivnu sposobnost krava utiču unutraš nji i spoljašnji faktori. Najznačajniji unutrašnji faktori su nasledni faktori i neuroendokrini sistem, a najznačajnijim spoljašnjim faktorima smatraju se ishrana, efekat klime, uslovi držanja, menadžmenta, zoohigijene i organizacija reprodukcije životinja. Sledeći reproduktivni poremećaji na farmi, koji su povezani sa deficitarnom ishranom dijagnostifikovani su svakodnevnim kliničkim pregledima: abortusi, anestrusi, endometritisi i patološki puerperijum. Neadekvatna ishrana takođe se može manifestovati kroz smanjenje fertiliteta i to pre pojave evidentih kliničkih simptoma. Podaci pokazuju da se pod izvesnim uslovima reproduktivne performanse mogu poboljšati dodavanjem hranivima β-karotina ili parenteralnom aplikacijom, dok dodavanje u ishrani i/ili parenteralno vitamina A i E smanjuje incidencu reproduktivnih poremećaja, prevenira retenciju sekundina i poboljšava fertilitet krava. Vrhunac laktacije (pik) je naročito kritičan period za mlečne krave pošto se preklapa sa graviditetom i povećanim potrebama u vitaminima i mineralima. Vitamini su naročito značajni kao regulatori katabolizma u telu. Za reprodukciju najznačajniji su vitamin A i β-karotin, koji igraju specifičnu ulogu u očuvanju strukture mikrosomalne membrane goveđeg žutog tela, dok se u citosolu vezuju za lipoproteine plazme. Svi vitamini, zajedno sa mineralima, značajni su zbog svojih uloga u metabolizmu ćelije. Cilj rada je bio da se ispita da li parenteralna aplikacije AD3E vitamina može prevenirati njihov deficit u hrani i kako ova aplikacija utiče na prevenciju reproduktivnih poremećaja.
