Abstract
In this study, financial losses due to several endemic diseases at the postpartum period of dairy cows were calculated, using the incidence rates and the financial losses from each clinical case of the endemic diseases reported in the literature. The median values of the incidence rates reported in the literature for retained placenta, clinical hypocalcemia, subclinical hypocalcemia, clinical metritis, clinical mastitis, clinical ketosis, subclinical ketosis, lameness and displaced abomasum were 8.6, 3.9, 33, 13.3, 7, 2.5, 19.8, 4.3 and 1.8% respectively. The average losses per case arising from retained placenta, clinical hypocalcemia, clinical metritis, clinical mastitis, clinical ketosis, lameness and displaced abomasum were calculated to be $257, $279, $278, $212, $109, $223 and $340 respectively. Using the above stated findings, the financial losses for each average cow arising from retainedplacenta, clinical hypocalcemia, clinical metritis, clinical mastitis, clinical ketosis, lameness, displaced abomasum and the total of 7 diseases were estimated to be $22, $11, $37, $15, $3, $9, $6 and $103 respectively.

Abstract
ABSTRACT Zebu and Holstein x Zebu crossbred have low incidence of uterine infection when compared to Holstein cows. Resistance to uterine infections may be associated with the ability to recognize invading microorganisms. Endometrial transcription of microbial molecular patterns receptors has been investigated in the postpartum period of Holstein cows, but it is completely unknown in Zebu or Holstein x Zebu cows. In this study, 9 Gyr and 12 F1 Holstein x Gyr cows were submitted to endometrial biopsies at the first and seventh days postpartum, with the objective to measure transcription levels of toll-like receptors (TLRs) 1/6, 2, 4, 5, and 9; nucleotide-binding oligomerization domain (NOD)-like receptors 1 and 2; and coreceptors cluster of differentiation 14 (CD14) and myeloid differentiation protein-2 (MD-2). There was a significant (P<0.05) decrease in transcription of TLR5 in Gyr, and an increase in transcription of TLR9 in F1 cows, between the first and seventh day postpartum. Both groups had low incidences of uterine infections up to 42 days postpartum. Uterine involution completed at 27.7 ± 10.1 and 25.1 ± 4.7 days postpartum for Gyr and F1 cows, respectively. In Gyr cows, higher transcription levels of TLR1/6 and NOD1 correlated to a longer period required for uterine involution. In F1 cows, lower levels of TLR1/6, TLR2 and NOD2 correlated to a longer period required for uterine involution. In conclusion, some pathogen recognition receptors associated significantly with the time required for uterine involution in Gyr and F1 cows.
