“…This unfavorable impact reduces reproduction reproductive efficiency; resulting in increased costs due to longer calving intervals; a decrease in the number of animals for replacement; a delay in genetic progress (Lima et al, 2010;Ribeiro et al, 2012); and higher involuntary culling and expenses related to animal nutrition, labor, and treatment, all of which affect the stayability of cows and the calving interval length (Giordano et al, 2011). Campos et al (2020) reported that the occurrence of postpartum diseases and clinical mastitis in a crossbreed dairy cows increased the number of artificial inseminations/conceptions. Dubuc et al (2011) indicated that uterine diseases reduce the conception rate and increase embryo loss and days open.…”

“…According to Buso et al (2018), crossbreed dairy cows, which present lower milk production levels than purebred animals, are less metabolically challenged during the postpartum period, leading to mildly compromised immune function. Thus, it is possible for these animals to recover spontaneously from uterine diseases, resulting in a smaller impact on reproductive efficiency (Campos et al, 2020). However, besides presenting a reduction in milk production, cows that present clinical health problems also often have milk disposal due to the treatment adopted, leading to relevant economic losses.…”

Retained placenta, metritis, and clinical endometritis are prevalent diseases on dairy farms, leading to economic losses and reducing the longevity of dairy cows in dairy production systems, so it is important to investigate potential predisposing factors. The aim of this study was to evaluate the relation between perineal hygiene during calving and the incidence of retained placenta, metritis, clinical endometritis and their effect on reproductive efficiency and culling rates in crossbred dairy cows. At two properties, pre calving cows (n=101) were evaluated for perineal dirtiness before and during calving, by visual observation and classified in score 1 - free of feces and dry perineum; score 2 - slight presence of feces and moist perineum; score 3 - mild-wet perineum, covered by feces (over 10% of the surface). After calving, cows were subjected by visual observation and gynecological evaluation to identify retained placenta, metritis and clinical endometritis. Cows with a hygiene score of 2 or 3 showed higher rates of retained placenta (41.9% x 14.0%), metritis (32.5% x 14.0%%) and clinical endometritis (42.5% x 15.8%) than cows with a score 1. Even though no significant effects on reproductive rates were reported, the degree of perineal dirtiness in prepartum dairy crossbred cows is associated with the incidence of post calving reproductive diseases.

“…Reproductive efficiency in dairy cows was challenged when there was reproductive disorders caused by infectious agents (Kustanti, 2016). Reproductive disorders were caused by infectious diseases caused by microorganisms, for example fungi, bacteria and viruses (Campos et al, 2020). Reproductive tract infections by bacteria could be caused by specific and nonspecific bacteria (Compton et al, 2017).…”

The purpose of this study was to determine the sensitivity of Staphylococcus aureus and Escherichia coli isolated from the reproductive tract of dairy cows during estrus to tetracycline, gentamicin, amoxicillin, and ciprofloxacin. Isolation and identification of E. coli and S. aureus from 24 cervical mucus samples resulted 15 samples containing E. coli and one sample containing S. aureus. Sensitivity test was performed using Kirby-Bauer (disc diffusion) method and interpreted using the Clinical and Laboratory Standards Institute (CLSI, 2017) guidelines. The sensitivity test of 15 isolates of E. coli showed 100% sensitivity to ciprofloxacin and tetracycline. For gentamicin, 14 (93.3%) isolates were sensitive, and 1 (6.7%) isolate was resistant, while for amoxicillin, 14 (93.3%) isolates were sensitive, and 1 (6.7%) isolate were intermediate. The sensitivity test of one isolate of S. aureus showed 100% sensitivity to ciprofloxacin, gentamicin, and amoxicillin; as for tetracycline 100% isolates were declared resistant.

“…Non-uterine diseases are also associated with reproduction failures. Clinical mastitis (CM), for example, up to 28 days postpartum (DPP) delays the normal ovary cyclicity and estrus (Huszenicza et al, 2005), reduces ovarian follicle growth rate (Lavon et al, 2011), increases the number of AI, decreases the chances of pregnancy in the rst AI and increases the days open (Campos et al, 2020;Dalanezi et al, 2020).…”

The purpose of this study was to evaluate the effect of retained placenta (RP) and clinical mastitis (CM) on the reproductive efficiency of crossbred dairy cows during the postpartum period and to investigate the effect of them in some innate immune system indicators. For this, in the first experiment a total of 232 crossbred dairy cows were evaluated and divided into three groups as: healthy control, RP and CM. The incidence of RP and CM was evaluated after parturition until 30 days postpartum (DPP) and reproductive rates were measured. In experiment 2, 30 crossbred dairy cows were divided into three groups as in Experiment 1. Between 40 and 50 DPP, clinical, gynecological examination and endometrial cytobrush were performed to evaluate subclinical endometritis and gene expression of interleukin- 1β (IL-1β), interleukin-6 (IL-6), chemokine ligand -5 (CCL5), estrogen α (ESR1) and progesterone (PGR) receptors by qRT-PCR analysis. In Experiment 1, the conception rate at 1st AI was lower in RP and CM groups and pregnancy rate at 150 days decreased in cows with CM. Calving-to-1st AI interval and days open were shorter in healthy cows. In Experiment 2 the occurrence of subclinical endometritis was 26.7% and was higher in cows with RP and CM. The expression of IL-1β was increased in RP and CM groups, while IL-6 was less expressed in RP group. The chemokine CCL5, ESR1 and PGR were similar between groups. In conclusion, cows with RP and CM had their reproductive efficiency negatively affected and had they initial pro-inflammatory response improved by the increase of IL-β, while, IL-6 was lower in animals with RP probably because it was evaluated later in the postpartum.
