The objective of study was conducted on to compare immunoglobulin (Ig) concentrations in calves raised under organic and conventional conditions. 30 newborn Holstein Friesian calves (15 rose under organic and 15 under conventional conditions) in two dairy cattle farms. Blood samples were taken from 30 newborn calves at birth (before taking colostrum) and on 14 th day to compare immunoglobulin (Ig) concentrations in calves raised under organic and conventional conditions. Furthermore, blood and colostrum samples were also taken from the mothers included into the study. IgG and IgM concentrations in colostrum and blood serums were determined using commercial ELISA kits. IgG concentrations at birth (0.79±0.34, 1.64±0.95 mg/mL) and on the 14 th day (46.5±21.5, 70.5±27.8 mg/mL) in calves raised under organic conditions were lower than those raised under conventional conditions (p<0.01). Calves raised under organic conditions also had lower IgM concentrations than calves raised under conventional conditions at birth (0.23±0.03 and 0.28±0.11 mg/mL, respectively) and on the 14 th day (2.76±0.56 and 4,30±1.03 mg/mL, respectively) (p<0.05, p<0.01). IgG concentrations in the blood serum of cows raised under conventional conditions were higher than those raised under organic conditions (p<0.01), while no difference was found with respect to IgM concentrations (p>0.05). No difference was found in the IgG and IgM concentrations of colostrum obtained from cows raised under organic and conventional conditions. In both the husbandry systems, positive and significant (p<0.01) correlations were found between the Ig concentrations of the mothers and offsprings. Consequently, it can be suggested that higher Ig concentrations in cattle raised under conventional conditions might be due to poorer environmental conditions.

Nutrition style and preference is one of the priority issues on which health-protective and disease-preventive measures are taken for a healthy life. For this purpose, functional foods that show beneficial effects on health as well as the nutrional value have become increasingly important. Among functional foods, probiotic foods which are produced by using probiotic microorganisms constitute the most important and interesting group. In order for a probiotic food to show its beneficial effect on health, it must contain minumum 106-107 cfu of microorganisms in grams or mililitres during its shelf life. Milk and dairy products are the foods in which probiotics are commonly used. However, the development of probiotic dairy products seems to focus on fermented milk (e.g., kefir) and yoghurt. Cheese has more advantages over fermented milk or yoghurts as a carrier food to intestinal environment due to the fact that it has a low oxygen content, high pH, high fat content and a firmer texture. In this review, the general characteristics of functional foods and probiotics are explained and evaluations are made using the potential of cheese as a probiotic carrier product. This study can shed light on new studies on the use of cheese as a functional probiotic food. Asian Australas. J. Food Saf. Secur. 2023, 7 (1), 20-32
