Summary
Calf survival rates dramatically improved with colostrum intake. Calves denied colostrum experienced high mortality and significant health issues, highlighting its critical role in bovine health.
Area of Science:
- Veterinary Medicine
- Neonatal Calf Care
- Bovine Immunology
Background:
- Colostrum is vital for passive immunity transfer in newborn calves.
- Calf mortality rates remain a significant concern in the livestock industry.
- Understanding the impact of colostrum on calf health is crucial for herd management.
Purpose of the Study:
- To investigate the survival rates of calves with and without colostrum intake.
- To identify health complications in calves deprived of colostrum.
- To assess the long-term health outcomes associated with early colostrum consumption.
Main Methods:
- Two groups of calves were studied: one receiving colostrum, the other denied colostrum.
- Mortality rates and clinical signs of disease were recorded.
- Post-mortem examinations were conducted on deceased calves to identify pathological changes.
Main Results:
- All calves that received colostrum survived.
- Calves denied colostrum had an 8/12 mortality rate, with one additional calf euthanized moribund.
- Health issues in non-colostrum-fed calves included bacterial organ infections, kidney sclerosis, joint disease, and rhinitis.
Conclusions:
- Colostrum administration is essential for neonatal calf survival.
- Deprivation of colostrum leads to increased susceptibility to infections and significant morbidity.
- Early passive immunity transfer through colostrum is critical for preventing disease and ensuring calf health.

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

01:22Imprinting
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.
01:08Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
00:55Parental Care
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
