The immunoglobulin concentration in bovine colostrum should be measured to ensure feeding with sufficient immunoglobulins (≥50 mg immunoglobulin G mL−1). Adequate feeding prevents diseases, promotes development, and has a positive influence on the adult animal. Indirect and direct measurement methods are available for this purpose. Direct measurement methods cannot be easily used in practice; therefore, farmers use indirect methods such as a colostrometer and a refractometer. Many factors influence the immunoglobulin concentration of colostrum; some of them have already been intensively researched. In particular, lactation and temporal aspects play an essential role. Newer aspects such as dry period, seasonal influences, and genetics are gaining importance, but their impact on immunoglobulin content has not been sufficiently investigated. Developments are still needed, especially in data management. This review analyzes the outcome of different studies on the indirect and direct measurement methods and discusses different factors influencing the immunoglobulin concentration of bovine colostrum.

“…Calves must ensure their passive immunity by consuming colostrum as soon as possible after their birth. Right time and sufficient supply of calves with quality colostrum is essential for the survival, could reduce mortality, strengthen immunity and increase livability of newborn (Janzekovic et al, 2014;Yaylak et al, 2018).…”

The study's main objective was to evaluate the colostrum quality (immunoglobulin G, IgG) at birth (0 h) and 3 h and 6 h after calving with different measurement devices foloving the comparison of the results among them. Colostrum samples (n = 63) were collected from 21 dairy caws. The colostrum quality was evaluated with a colostrometer and digital and optical refractometers. Digital and optical refractometers showed no significant (P > 0.05) diference in obdeind results, while colostrometers exhibited significantl (P ≤ 0.05) lower concentrations of IgG. Differences were detected in all three considered times. The colostrometer proved to be less accurate. The optical refractometer proved to be the most useful for on-farm assessment because the results were comparable to the digital and it was affordable.

The utilisation of different by-products from the food industry as nutrient sources for farm animals is both possible and beneficial. Grape pomace is a by-product that contains polyphenols and fatty acids, both of which have the potential to improve the nutritional quality of cow colostrum. This study aimed to explore how the addition of grape pomace to the diet of dry cows affects the concentration of nutrients and fatty acids of colostrum. Sixteen Slovak spotted cows in late pregnancy were used in this study. From the seventh day before expected calving to the day of calving, cows in the grape pomace group received a diet supplemented with dried grape pomace, at 0.116 kg/cow/day. Colostrum samples were analysed for basal nutrients and fatty acid concentrations. Between the control and experimental groups, the nutrient and fatty acid concentrations of all the colostrum samples did not show significant differences. The nutrient levels in the colostrum from both groups of cows were typical, as related to the time from calving. The addition of the grape pomace into the diet of dry cows had no effect on nutrient concentrations and the fatty acid composition of the colostrum. The somatic cell score of the colostrum sampled at the 12th hour after calving (4.2 versus 2.6) was positively affected by grape pomace addition. The results of this study revealed that grape pomace (fed in an amount of 0.116 kg/cow/day) had no positive or negative effect on the base nutrients and fatty acids of cow colostrum, and, therefore, grape pomace can be used as a nutrient source for dry cows in small amounts.
