Abstract
The work presents the results of investigations of the effect of natural zeolite (clinoptilolite type) on the degree of resumption of cloistral immunoglobulin, the value of hematological parameters and enzyme activity in blood serum (AST, ALT, and LDH), body mass, and daily growth of calves in the first three months of life. Investigations were carried out on three groups of 10 male and female calves each, with a 1:1 ratio of sexes, (control, K, and two experimental groups, I and II), of the black-and-white breed, Holstein type. All three groups of calves were fed with the usual rations (colostrum, collective cows' milk, fodder mix with 18% total proteins, and Lucerne hay).The experimental groups of calves, as opposed to the controls, received colostrums and collective cows' milk with the addition of a preparation based on natural zeolite in quantities of 5 and 10 g/l milk. The concentration of immunoglobulin G in blood serum of experimental groups of calves was significantly higher than the values of the control group (35.9?6.43 g/l in Group I; 32.5?7.39 g/l in Group II; 20.8?6.88 g/l in control group K). The results of the investigations of the values of hematological parameters (number of erythrocytes, hemoglobin concentration, and hematocrit value) do not show any digressions from the physiological values and are approximately the same in the experimental and the control groups of calves, which indicates that the examined quality of the zeolite-based preparation did not affect the degree of the resumption of iron and other oligoelements significant for erythropoietin. The data on the enzyme activity in blood serum indicate that the examined preparation does not cause any significant functional or morphological changes in the tissue of parenchymatous organs or muscles. There were no significant disorders in the health of calves of the experimental groups, while 3 calves of the control group had gastrointestinal disorders (diarrhea). Calves of experimental group I which received colostrum and collective cows' milk with an addition of 5g zeolite/l milk had a significantly greater average body mass and daily growth on the 90th day of life than calves of the control group (116.0-6.9: 105.3-6.4 kg, and 0.868:0.743 g). The addition of natural zeolite in quantities of 5 g/l colostrum or milk yields better results and has an advantage over the higher doze of zeolite of 10 g/l.
Highlights
U radu je dat prikaz rezultata ispitivanja uticaja prirodnog zeolita (u tipu klinoptilolita) na stepen resorpcije kolostralnih imunoglobulina, vrednosti hematolo{kih parametara i aktivnost enzima u krvnom serumu (AST, ALT i LDH), telesnu masu i dnevni prirast teladi u prva tri mesecaivota
Za razliku od kontrolne, dobijale su kolostrum odnosno zbirno kravlje mleko sa dodatkom preparata na bazi prirodnog zeolita u koli~ini od 5 odnosno 10 g/L mleka
Telad I ogledne grupe koja su dobijala kolostrum odnosno zbirno kravlje mleko sa dodatkom 5g zeolita/L mleka imala su 90. danaivota zna~ajno ve}u prose~nu telesnu masu i dnevni prirast od teladi kontrolne grupe (116,0 ± 6,9 :105,3± 6,4 kg), odnosno (0,868:0,743 g)
Summary
[amanc i sar.: Uticaj prirodnog zeolita na biohemijske i hematolo{ke parametre krvi, telesnu masu i prirast teladi zna~ajno u ishrani mla|ih kategorija koje se hrane preteno koncentrovanim hranivima sa visokim sadrajem proteina. [amanc i sar.: Uticaj prirodnog zeolita na biohemijske i hematolo{ke parametre krvi, telesnu masu i prirast teladi tracija imunoglobulina u njihovom krvnom serumu vi{a tokom prva 24 sataivota (McEwan i sar., 1970). Ovi autori pretpostavljaju da prisustvo preparata na bazi zeolita u digestivnom traktu novoro|enih teladi i prasadi zna~ajno smanjuje negativni uticaj procesa raspadanja hrane u crevima (koji nastaje kao posledica uno{enja kolostruma sa visokom koncentracijiom proteina) na sloene mehanizme u procesu resorpcije intaktnih molekula imunoglobulina kroz epitelne }elije sluzokoe creva.
