Plain English Summary

Background and study aims
Respiratory infections are a major cause of disease and death in developing countries. Diarrhea is also a major killer in children under five and recurrent diarrhea affects nearly 20% of the population. Fighting against these disease is a matter of the highest importance for mothers all over the world. Breastfeeding is the most cost-effective way to protect children against infectious disease, because milk contains substances that fight infection. Colostrum is the first milk produced after delivery of a baby. It contains concentrated nutrients and antibodies. Bovine colostrum (BC) from cows' milk has high levels of anti-infective components that are similar to the substances in human colostrum. The daily use of BC has been reported to have a protective role for infantile gastrointestinal disease due to its direct effect on enhancing immunity in the gut. Studies in infants indicate the possible treatment and preventive role of oral BC against many infectious diseases of infants. However, there is no research to study the preventive role of BC on infectious disease in formula milk feeding infants. The aim of this study is to look at the effect of BC on the prevention of diarrheal and respiratory disease in infants.

Who can participate?
Infants aged 6-9 months who are fully formula feeding after birth

What does the study involve?
Infants will be randomly assigned to one of the two groups, either the intervention or the control group. Infants in the intervention group will be given a commercially available BC sachet once a day for 3 months, which can be mixed with 30-50 ml of warm water (below 40℃), or added to milk, rice cereal, soup, rice porridge and other foods. Infants in the control group will not be provided with any BC sachets. Basic information will be collected, including family socioeconomic status, levels of main caregivers, family monthly income, and use of vitamin/mineral supplement before the study. Parents will be requested to inform the health care workers if their babies experience any symptoms of diarrheal or respiratory disease. Before and after the study, the babies weight, length and head circumference will be measured and babies feces will be analysed.

What are the possible benefits and risks of participating?
During the trial, infants' parents will obtain knowledge about healthcare, disease development and disease monitoring for their babies. The possible risk to participants is that infants may be allergic to BC; however, any infants with a personal or family history of allergies to cow's milk or intact infant formula, eczema, allergic rhinitis or asthma will not be able to take part.

Where is the study run from?
Angel Children's Hospital Chengdu (China)

When is the study starting and how long is it expected to run for?

Scientific title

The role of bovine colostrum as prophylaxis for respiratory infections and diarrhea in formula feeding infants after birth


Study hypothesis

We addressed the hypothesis that formula fed infants supplemented with bovine colostrum (BC) will have reduced morbidity of diarrhea and respiratory tract infections (RTIs) compared with infants who only received formulas without bovine colostrum

Ethics approval

Infants fully formula feeding after birth


Eligible infants were randomly assigned to one of the two intervention groups. Infants in the intervention group (IG) were given a commercially available bovine colostrum (BC) sachet (Hainan Govking High-Tech Dairy Industry Co., Ltd, Haikou, China, Product Batch Number: D7010) once a day, which contained a bovine IgG concentration of 200 mg/g per sachet. Each sachet (1.0 g) can be mixed with 30-50 ml of warm water (below 40°C), or added to milk, rice cereal, soup, rice porridge and other foods. Infants in the control group (CG) were given no BC sachet. The intervention duration was three months.
