The main strategy to prevent bovine rotavirus group A (RVA) diarrhea in calves is to vaccinate late-term dams aiming to enhance passive immunity transfer of specific immunoglobulins against the virus. This study aimed to evaluate influence of parity in titers of immunoglobulin G (IgG), IgG1 and IgM in serum and colostrum of vaccinated or unvaccinated Holstein cows and in serum of its calves, associated with monitoring for RVA diarrhea in calves. Cows and its calves were allotted into groups according to parity and vaccination (primiparous/multiparous; vaccinated/ unvaccinated) and serum and colostrum samples of cows were taken as well as serum and fecal samples of its calves. Parturition influenced colostral titers of IgG and IgG1, which were higher in multiparous cows, whilst IgM titers were influenced by vaccination, being higher in colostrum of vaccinated dams. Lowest serum titers of IgG and IgG1 were found in calves born to unvaccinated primiparous dams. Eleven calves presented RVA diarrhea, and genotypes G6P [11] and G6P [5] were found in the vaccinated and unvaccinated herds, respectively. Vaccination of dams prolongs humoral immunity in calves and enhances colostrum quality and should be a primary concern in primiparous cows.

“…Calves rely on placental transfer of nutrients during fetal development and colostrum and milk nutrient concentrations immediately post-calving. Additionally, colostrum serves as the main source of minerals for the newborn calf [ 92 ]. If colostrum mineral concentrations are altered or deficient immediately post-calving, calves may also have reduced mineral concentrations, which could negatively impact health and production.…”

Nutritional status can have major implications for animal health and production. Energy balance is easily determined using a body condition scoring system. This allows producers to readily adjust diets to meet an animal’s needs. Far less obvious is an animal’s trace mineral status, which is typically not assessed until an animal’s performance falls below expectation or illness is detected. Trace mineral toxicities and deficiencies can manifest as reduced thriftiness and/or poor reproductive performance, resulting in economic consequences for producers. Maternal mineral status not only impacts dam heath, but also the health of subsequent offspring. Both the oocyte and embryo are susceptible to changes in maternal mineral status. This susceptibility is maintained throughout fetal development via placental control of nutrient transfer to the fetal system. Furthermore, maternal mineral status continues to impact offspring health via colostrum and milk quality. Herein we discuss the roles of trace minerals in bovine reproductive performance, maternal health, colostrum and milk quality, and offspring health.

“…The composition and physical characteristics of colostrum depends on many factors such as age, parity, breed, diet, vaccination status, and history of diseases (10, 11). Rocha et al have concluded that parity is an important factor in relation with LF concentration (11). The concentration of the LF in colostrum milk in highly lactating cows is four times higher (2,000 µg/mL) than in the fattening breeds (500 µg/mL) (12,13).…”

The health condition of the mammary gland is highly crucial for obtaining good quality colostrum. The lactoferrin (LF), as an iron-binding protein, plays a key role in the defense mechanisms of the mammary gland due to its’ bacteriostatic properties. The study aimed to investigate the factors affecting the LF concentration in the bovine colostrum milk during the postpartum period, and the effect of somatic cell count (SCC) on the LF concentration and milk composition. The cows were randomly selected at a dairy farm in Pelagonia region. Colostrum samples from 12 cows were collected. Samples were taken at different time intervals after parturition, 1, 6, 12, 24, 48, 72, 96, and 120 h after parturition. Cows in their second parity were found to have higher levels of LF compared to cows in the third and higher parity (p>0.05). Time had a significant effect on the LF concentration (p<0.01), with the highest value recorded 1 h after parturition remaining stable for one hour. LF concentration and SCC in the colostrum showed a weak positive correlation (r=0.40; p<0.01). The highest LF concentration was noticed when SCC was above 800,000 cells/mL. In conclusion, the colostrum LF concentration was significantly affected by the interactions of the two factors, i.e., time after parturition and SCC (p<0.05). Milk composition was affected by elevated SCC. Parity showed no association with LF. The SCC can be used as a reliable means of assessing colostrum quality.
