“…P. multocida is a common coloniser of the upper respiratory system and only occasionally associated with mastitis. Transmission usually occurs from cow to cow, but lymphogenic or haematogenic spread from the respiratory tract to the mammary glands has been discussed [ 19 , 38 ]. In addition, there is evidence of transmission via suckling calves.…”

“…At this point, further investigations with a control group are required. Moreover, cows with teat lesions have an increased risk of IMI caused by P. multocida, as the pathogen can multiply in them [ 38 ]. The foster cows in the current study had a significantly higher number of teats with lesions at the end of the foster period ( p < 0.001), which were probably caused by the calves’ teeth.…”

To date, there have been few studies on the health effects of foster cow systems, including the transmission of mastitis-associated pathogens during suckling. The present study aimed to compare the pathogens detected in the mammary glands of the foster cow with those in the oral cavities of the associated foster calves and to evaluate the resulting consequences for udder health, calf health and internal biosecurity. Quarter milk sampling of 99 foster cows from an organic dairy farm was conducted twice during the foster period. Oral cavity swabs were taken from 345 foster calves. Furthermore, quarter milk samples were collected from 124 biological dams to investigate possible transmission to the foster cows via the suckling calves. All samples were microbiologically examined and confirmed by MALDI-TOF (matrix-assisted laser desorption time-of-flight mass-spectrometry). Using RAPD-PCR (randomly amplified polymorphic DNA polymerase chain reaction), strain similarities were detected for Pasteurella multocida, Staphylococcus aureus, S. sciuri and Streptococcus (Sc.) suis. Transmission of P. multocida and S. aureus probably occurred during suckling. For S. sciuri and Sc. suis, environmental origins were assumed. Transmission from dam to foster cow with the suckling calf as vector could not be clearly demonstrated.

“…The second examination at the end of the suckling period showed a high prevalence of Pasteurella ssp., which were often associated with subclinical mastitis. Pasteurella (P.) multocida is usually regarded as a coloniser of the upper respiratory system and only occasionally as a cause of mastitis [28,35]. In addition to transmission from cow to cow, a distribution via blood and the lymph from the respiratory tract might also be a possible route to infect the mammary gland [28].…”

Effects of Suckling on the Udder Health of Foster Cows

et al. 2021

In a foster cow system, one or more calves are reared by a foster cow. With regard to the growing rejection towards the early separation of cow and calf after calving, such alternative rearing methods with prolonged cow–calf contact are coming more into focus. Nevertheless, there is a lack of recent studies investigating the effects of suckling multiple calves on the udder health of a foster cow. The present study aimed to initially describe the status and development of the udder condition and the microbial colonisation during the foster period. Thereby, the objectives were to determine whether suckling multiple calves was associated with an increase in intramammary infections (IMI) and a deterioration of udder constitution. A total of 99 Holstein Friesian foster cows from a large organic dairy farm in eastern Germany were included in this pilot study. Each foster cow was suckled by 3–4 calves and not additionally milked. Quarter milk samples were taken for cytomicrobiological examination at the beginning and end of the approximately 3.5 months suckling period. At the same time, the udders of 91 of these foster cows were clinically examined by visual assessment and manual palpation. In both the first and second examination (E1 and E2, respectively), Corynebacterium ssp. and non-aureus staphylococci (NaS) constituted the most frequently detected pathogen species in the 385 examined udder quarters. Classifying the quarters into mastitis categories was significantly different between the two examinations (p = 0.001). The number of quarters considered as healthy increased from E1 to E2 by 8.5%. At the same time, the number of quarters with mastitis decreased by 2.6%, the number of quarters with non-specific mastitis by 11.4% and the number of quarters with a latent infection increased by 5.4%. In total, 69.4% of the 121 infected udder quarters in E1 were bacteriologically cured in E2. A cytological cure was achieved in 28.1% of the 385 quarters. Both the bacteriological and cytological cure rate were spontaneous. A new infection occurred in 23.1% of the 385 examined udder quarters and was mainly attributable to infections with Corynebacterium spp. and NaS. During the suckling period, mainly new infections occurred and amounted to 73% in relation to presumed persistent infections (18.9%). The new infections were mainly attributable to infections with Corynebacterium spp. and NaS. Pasteurella spp. were also found in high percentages. A total of 10.1% of the quarters showed an increase in somatic cell count (SCC) above the threshold of 100,000 cells/mL from E1 to E2, indicating a new subclinical mastitis. Regarding udder condition, significant changes during the foster period were an increase in udder skin and teat lesions, a decrease in udder oedema, an increased amount of udder quarters with a consistency considered as normal and an increase in the number of udders showing no sign of udder cleft dermatitis. Moreover, teat length, circumference, and diameter increased significantly (p < 0.05). In conclusion, there is a possibility that suckling multiple calves improves udder health in terms of mastitis but leads to an increased pathogen transmission at the same time, resulting in an increase in latent infections. Additionally, pathogens as Pasteurella spp., which are usually located in the upper respiratory system, could be detected in the mammary gland. The changes concerning the udder condition were manifold. However, it has not yet been conclusively clarified whether all these changes are exclusively due to calf suckling. Further investigations with a non-suckled control group are required.

“…Supportive therapy is also important as it enables faster recovery of the animal and restoration of milk supply. This aspect of therapy is often neglected in practice although the importance of supportive therapy is indisputable (Boboš et al 2012(Boboš et al , 2014Milanov et al 2017;Katić 2012).…”

Mastitis is one of the most important health problems in dairy cows. In addition to thehealth aspect and the apparent impact on animal welfare, mastitis is the largest financial cost in dairyfarms due to treatment costs and rejected milk because of the withdrawal period, as well aspermanently reduced milk production or complete lactation interruption in heavy form of mastitis.The procedure and the outcome of the treatment depend on the form of udder inflammation, degreeof tissue alteration, timing of treatment initiation and the application of adequate preparations or theappropriate procedure. The outcome of therapy can be full restitution of parenchyma and its functionor deterioration of the glandular parenchyma and filling with connective tissue. Nowadays, inconditions of intensive milk production, mastitis therapy is only part of a mastitis control programthat puts mastitis prevention at the forefront. In case of clinical mastitis, it is necessary to applytherapy during lactation.
