Summary: The study suggests that providing calves with a second feeding of colostrum within 5-6 hours of birth has positive effects on calf health, reducing the risk of failure of transfer of passive immunity and morbidity, and optimizing pre-weaning average daily gain. However, there is no significant impact on pre-weaning mortality and reproductive efficiency.

Summary: Gastrointestinal disease is the leading cause of mortality in dairy calves, with septicemia being a significant consequence of diarrhea. Empirical antimicrobial therapy is justified primarily for the prevention of bacteremia, but it is currently not necessary for diarrheic calves without signs of depression.

Summary: This study demonstrated that adding nucleotide supplementation to whole milk can improve post-weaning intake and final body weight of calves, as well as reduce days with loose feces in the first month of life. While no effects on pre-weaning performance were observed, nucleotide supplementation showed positive effects on overall health and intake of calves.

Summary: The research found that diseases occurring before weaning have some long-term effects on the production and reproductive performance of replacement heifers, but have limited impact on the time to achieve critical reproductive performance indicators.

Summary: The feeding of trehalose in preweaned calves can improve the gut environment, reduce medication frequency, promote the production of butyrate, and influence the microbial community structure in the gut.

Summary: The study investigated the effects of neomycin on calf health and growth performance, finding that calves in the control group experienced more days of diarrhea and higher fecal scores than those in the groups receiving neomycin. However, there were no differences in growth performance, feed intake, and feed conversion ratio among the groups. Calves receiving neomycin did not show additional health benefits beyond reduced fecal scores.

Summary: The study aimed to evaluate the effects of adding lysolecithin in milk replacer on the performance, metabolites, and gut health of preweaned dairy calves. The results showed that supplementation of lysolecithin increased average daily gain, feed efficiency, and improved fecal score in preweaned calves.

Summary: This experiment aimed to investigate the effects of milk-derived bioactive tripeptide VPP (Val-Pro-Pro) on the growth, diarrhea incidence, serum biochemical indices, short-chain fatty acids, and fecal microorganisms in pre-weaning Holstein calves. The results showed that oral administration of VPP can alleviate intestinal inflammation and reduce the degree of diarrhea in calves.

Summary: Dairy calf nutrition has a significant impact on the efficiency and profitability of dairy operations but is often overlooked. Research in the past decade has focused on mitigating high rates of disease and death among calves to improve animal health, growth, and industry sustainability. Major knowledge gaps still exist in crucial stages of development, highlighting the need for more comprehensive research to ensure the long-term sustainability and efficiency of the global dairy industry.

Summary: This experiment studied the long-term effects of different preweaning feeding methods on dairy cattle's immune system. It found that high volume feeding resulted in better immune response during the preweaning phase, and this effect continued even after 9 months of weaning. These results highlight the positive impact of preweaning nutrition on the development of the immune system in dairy cattle.

Summary: Retaining replacement heifers born from primiparous cows mated by artificial insemination can enhance genetic gain rates. Although heifers born from primiparous cows may be lighter at birth and grow at a slower rate, they tend to produce more milk than heifers born from multiparous dams. Additionally, the reproductive performance and milk production of heifers born from primiparous dams are comparable to those born from multiparous dams.

Summary: The study found that Holstein-Friesian-Jersey crossbred heifers grown in a linear trajectory reached puberty 38 days earlier than those grown in a seasonal manner; there was no impact on first lactation milk production between different growth trajectories; however, heifers in the seasonal group were slightly taller than those in the target group.

Summary: This study investigated the impact of Bovine coronavirus, Bovine rotavirus, and Cryptosporidium parvum on dairy calf health and performance. The prevalence of these pathogens significantly affected the incidence of diarrhea and body weight gain in calves.

Summary: The study found that the lying, inactive, and active times of calves one day before the onset of diarrhea can serve as early indicators for detecting the disease. Using an accelerometer system, these behavior patterns were effectively monitored and showed potential for early detection of neonatal calf diarrhea.

Summary: This 8-year retrospective study in Southeastern Iran calculated the percentage of meat and organ condemnations at four slaughterhouses, finding that parasitic lesions led to direct economic losses, with liver and lung condemnations being the most prevalent. The study estimated a total direct cost of U.S. $ 3,191,879 due to condemnations caused by parasitic infections.

Summary: Bovine respiratory disease (BRD) is a common and complex disease process in calves, and early detection can be challenging. This study used thoracic ultrasonography (TUS) to monitor lung consolidations in Iranian dairy calves and found that lung consolidation had a negative impact on preweaning growth.
