The aim of this study was to compare the potential effect of rat consumption of different dairy products such as buffalo colostrum (BC), full fat yoghurt (FFY), fermented milk (FM), fermented milk supplemented with probiotics (FMSP), and whole milk (WM) on diff erent parameters; immunological, histological, bacteriological and biochemical in an animal model. Rats were fed at 10% of diff erent dairy products in their diets. The rats which were fed on buff alo colostrum diets showed higher levels of serum immunoglobulin, an improvement of liver functions, and histology of colon and liver tissues and lower percentage of body weight gain compared with other diet groups. Meanwhile the fermented milk diet showed the least improvement compared to the control group.

Key words: colostrum, dairy products, rats, histology, liver functions, immunology, intestinal microflora


Potencialni učinek nekaterih mlečnih izdelkov na delovanje jeter, imunost in črevesno mikrobioto pri podganah

Namen raziskave je bil primerjati pri podganah potencialni učinek zauživanja različnih mlečnih izdelkov, kot so kolostrum vodnega bivola (BC), jogurt s polnimi maščobami (FFY), fermentirano mleko (FM), fermentirano mleko dopolnjeno s probiotiki (FMSP), in polnomastno mleko (WM) na različne lastnosti kot so: imunološke, histološke, bakteriološke in biokemične na živalskem modelu. Podgane so bile krmljene z vključitvijo 10% različnih mlečnih izdelkov v njihov obrok. Podgane, ki so bile krmljene s kolostrumom vodnega bivola so imele višje vrednosti imunoglobulinov v serumu, izboljšano delovanje jeter in histologijo na debelem črevesu in jetrih tkiv ter nižji odstotek telesne mase v primerjavi z drugimi skupinami. Prehrana z dodatkom fermentiranega mleka se je pokazala z najmanjšimi izboljšavami v proučevanih lastnostih v primerjavi s kontrolno skupino.
