Clinical signs, bacteriology and blood biochemistry in repeat breeder Fresian cows, Onl J Vet Res., 22
(9):749-753, 2018.
Repeat breeder cow syndrome (RBC) is a major cause
of reduced fertility in dairy cows. Authors describe signs, bacteriology and blood
biochemistry in 60 Fresian cows with RBC. Results
were compared with 80 normal controls. The animals were swabbed for
bacteriology and blood taken for hematology and biochemical values. We found
higher incidence (P < 0.05) during summer months (45%). Vaginal epithelium was
hypertrophied with mucous or purulent secretions in about a third of repeat
breeders and mostly with staphylococci (42%) with or without other
bacteria. Repeat breeders had higher (P < 0.05) mean blood urea (28.3 mg/L)
and cholesterol (289 mmol/L) compared with controls
(24.5 mg/L and 174 mmol/L), respectively. Mean
glucose (43mg/dl), protein (8.3 g/L), zinc (9.2mmol), Mn
(0.554 μg/mL) and Fe (0.419 μg/mL)
were lower compared with controls (51 mg/dL,
10.75 g/L, 14.6μmol/L, 0.754 μg/mL and 0.62
μg/mL), respectively. Bacterial infection contributes
to repeat breeder syndrome with consequent changes in blood biochemical values.
