Effects of Suckling on the Udder Health of Foster Cows

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