The postpartum phase is linked to a higher risk of removal from the herd and a higher incidence of most dairy cattle illnesses. Risk factors for postpartum disorders are frequently shared, and these factors can set off a chain reaction of additional illnesses. The transition phase, which lasts three to four weeks before and after calving, is critical for a cow's health and longevity, as well as the lactation's profitability. At any stage during the lactation cycle, calving is accompanied by the most dramatic endocrine alterations. Cows going through the transition period also endure significant immunological suppression as their energy balance shifts from positive to negative. Aside from the development of certain diseases, the removal of a cow from the herd during the postpartum time (due to culling or death) is another sign of difficulties during the transition phase. Healthy cows are rarely culled after giving birth since they can continue to give milk for the rest of the lactation. According to a study, early lactation removals are more likely to be due to death or injury than later lactation removals, implying that herds with high early-lactation cull rates are more likely to have poor transition cow health. Early-lactation removals are beneficial in the evaluation of postpartum difficulties since cows may develop serious disease and die or be removed from the herd before being properly detected or treated. Premature herd elimination could be avoided with more intensive surveillance or preventive treatment.

Metritis develops within 21 days following delivery, with most cases occurring during the first 10 days. Metritis is marked by an enlarging uterus and a watery red-brown fluid to thick off-white purulent uterine discharge with a fetid odor. The indications of health are used to classify the severity of sickness. The change to disease prevention rather than treatment, as well as the shift from individual cows to groups of cows at risk, have been the most significant breakthroughs in dairy health in recent decades. Awareness the biology of transition dairy cows requires an understanding of the complex nature of practically all diseases and the interrelated risk factors. Inflammation of the endometrium causes subclinical endometritis, which causes a considerable loss in reproductive performance in the absence of indications of clinical endometritis. The inflammation is thought to be linked to tissue recovery following clinical endometritis, trauma, or other non-microbial illness. In the absence of clinical endometritis about 5 weeks postpartum, subclinical illness is defined by polymorphonuclear neutrophils (PMNs) reaching 5.5 percent to 10% of cells in samples taken by flushing the uterine lumen or by endometrial cyto brush. The percentage of animals with subclinical endometritis varies depending on the diagnosis cutoff and the time following parturition, but it ranges from 37 to 74 percent. E. coli infection occurs before infection with other microorganisms that cause endometrial structure and function to be disrupted.

Endometrial cells TLRs detect pathogen-associated compounds (PAMPs) such as LPS, DNA, and bacterial lipids, alerting the innate immune system to the presence of pathogens. To direct the immune response, endometrial cells release cytokines and chemokines, as well as boost the expression of antimicrobial peptides (AMPs). Although neutrophil activity is commonly disrupted in postpartum dairy cows, chemokines recruit PMNs and macrophages to remove germs. The primary characteristic of subclinical endometritis is the persistence of PMNs in the endometrium in the absence of bacteria. Ovarian function is also affected by uterine illness. Cows with uterine bacterial infections had delayed ovarian follicle growth and lower peripheral plasma estradiol levels, making them less likely to ovulate. Subclinical hypocalcemia can result in decreased rumen motility, which can lead to lower feed intake, ketosis, and a displaced abomasum. Dystocia can be caused by hypocalcemia due to inadequate uterine motility, which raises the risk of retained placenta and metritis. Metritis or ketosis, on the other hand, can arise without underlying hypocalcemia and can be main diseases that set off a chain reaction of postpartum complications. Infertility is caused by microbial infections of the genital tract that affect uterine and ovarian function.
