   Abstract 

Background: Milk and dairy products from animal sources (cow's milk or buffalo's milk) are an important part of Indian diet and its consumption starts at an early age. Objective: The purpose of this study is to understand the processing, storage and modifications carried out before bovine milk is fed to the infants and compare it with recommendations by Health Care Professionals (HCPs). Materials and Methods: The study involved assessments involving HCPs and mothers of children below 1 year of age through both qualitative and quantitative methods. Feeding recommendations by HCPs were assessed through a quantitative method. Results: The children are commonly initiated on bovine milk post 3 months of age. The milk is not covered while boiling in 70% cases and boiled at suboptimal temperature (moderate: 62% or low: 31%). Half of the families store milk outside refrigerators openly in the kitchen or rooms. The milk is modified in the majority of cases (81%) before being fed. Modification of the milk was often done with sugar (85%), followed by water (49%), biscuits, fennel seeds, cardamom or infant cereals before feeding the baby. Addition of water was more prevalent among mothers of infants between 3 and 6 months. HCPs do not advise consumption of bovine milk by infants unless there is no other option available. Conclusion: A clear gap exists between recommended and actual practices for infant feeding in India. There is a huge opportunity to educate mothers on importance of breast feeding and benefits of implementing appropriate processing, storage, and consumption practices of bovine milk.

   Introduction Top


Milk and dairy products from animal sources (cow's milk or buffalo's milk) are an important part of Indian diet and its consumption starts at an early age. It is reported that 15% of infants below 6 months of age receive milk from other sources along with breast milk. [1]

World Health Organization (WHO) recommends exclusive breastfeeding for infants up to 6 months of age continued breastfeeding up to 2 years or beyond. [2] Feeding practices in infants differ widely due to socioeconomic practices and false perceptions like dilution of milk (from animal sources) for easy digestion. [3]

There is paucity of data to evaluate specific feeding practices that are prevalent in general population. Further, many of the practices pertaining to dilution, storage conditions, and addition of condiments have a bearing on the nutritional as well as microbiological quality of milk. [4],[5] The data with respect to practices involved in handling of the bovine milk in household are also lacking. To understand better the common household practices of processing, storage and modifications carried out before consumption of bovine milk in infants, this survey was conducted to analyze the bovine milk usage practices in India. The study also assessed difference in actual feeding practices with recommendations by Health Care Professionals (HCPs).


   Materials and Methods Top


This research study has been conducted independently by TNS India Pvt. Ltd. on behalf of Nestlé India Pvt. Ltd. TNS India decided on research methodology (including choice of centers, sample size across centers, reporting criteria, etc.). This was a community based study and the data collection for this research was conducted during the period October 2009 to November 2009. The study involved quantitative and qualitative analysis of milk feeding practices from mothers and HCPs. Eight centers from different states across four zones (North, East, South, and West) in India with equal representation of one metro and one mini-metro city/town in each zone was selected for the study. The centers included in the research were: Delhi and Ludhiana (Punjab) in North; Kolkata (West Bengal) and Patna (Bihar) in East; Mumbai (Maharashtra) and Nagpur (Maharashtra) in West; and Chennai (Tamil Nadu) and Cochin (Kerala) in South. All mothers who participated in this study had infants in the age group of 0-12 months. An equal representation of infants in the age group of 0-6 month and 7-12 month was maintained across all the centers. The participants in each group belonged to different socioeconomic classes (SEC) A, B and C based on parameters defined in [Table 1]. Indian population has been classified under 8 SEC grades (A1 to E2) by Market Research Society of India (MRSI) on the basis of two parameters: Occupation and Education of the chief wage earner (Head) of the households. The distribution of the socioeconomic group was similar across all centers [Table 2]. Further, representation from both working and nonworking mothers were included to ensure the reporting of feeding practices across categories. Mothers feeding their infants only cow's or buffalo's milk or both including other milk substitutes were included in the study.

Quantitative Assessment

Data were included from 800 respondents for the quantitative analysis. A statistically significant sample size for a set of homogenous set of respondents is 30. Considering dropouts a higher sample size of 50 respondents was included. Since in each centre, the participants belonged to two homogenous groups (infants with 0-6 months of age and 7-12 months of age), at each centre 100 respondents were included leading to a total sample size of 800 respondents from eight centers. Mothers were interviewed to obtain information on milk feeding practices. Mothers were selected using random sampling methodology. Starting points (SP) were chosen randomly from each centre using an electoral method. At each starting point, using the right hand rule, the interviewer went to the house that was to the right and skipped 2 houses after every successful interview. Face-to-face interview using a well-structured questionnaire was conducted. Interviews were recorded verbatim by research associates. All interactions were held in the local language of the respondents. Information was obtained on the type of milk purchased, type, and quantity of milk feeds given to the infants and the entire storage, processing, modification, and consumption procedures. The variables analyzed in the quantitative phase were: (1) purchase and storage practices adopted by mothers; (2) methods of cow's/buffalo's milk modification in terms of treatment and addition of supplements; (3) effect of infant's age on the method of modification of cow's or buffalo's milk.

Qualitative Assessment

In the qualitative phase, data from 20 mothers and 40 HCPs were included. From each centre, five HCPs participated in the research. Of the total, 60 interactions carried out in the qualitative phase, there were four focused group discussions and 16 in-depth interviews with mothers and 40 in-depth interviews with HCPs [Table 2]. Focused group discussions allowed exchange of ideas and viewpoints and helped gain a wider understanding of differing viewpoints on the usage of cow's or buffalo's milk. In-depth interviews helped in obtaining detailed information on the process of milk-feeding practices. HCPs included in the analysis were pediatricians with more than 5 years of work experience in renowned hospitals and they were interviewed. From mothers perspective, the parameters observed were: (1) triggers and barriers towards adoption of cow's/buffalo's milk for the infants; (2) modification of milk and the reason for modification. The parameters assessed from HCPs perspective were (1) recommendations for feeding cow's/buffalo's milk to the infants; (2) type of milk recommended; (3) recommendation for quantity of milk to be fed, and (4) modification required in the milk before feeding.

Overall the following parameters were analyzed using the variables from quantitative and qualitative phase: (1) the reason mothers feed cow's/buffalo's milk to their infants, (2) the methods involved in feeding, (3) the gap between HCP's recommendation and actual practice of usage and processing of cow's or buffalo's milk.

Quantitative Assessment

Age of initiation of bovine milk:
In this study, the children on an average are initiated on bovine milk post 3 months of age although mother's milk has a higher stomach share (6 out of total 8 feeds per day) as compared to other forms of milk. In the North region, the child is started on bovine milk as early as 2.5 months of age. Initiation of bovine milk feeding to infants has been also reported to be relatively early in SEC A.

Purchase practices
: Overall, loose cow milk (28%) and single toned packet milk (28%) were mostly purchased followed by loose buffalo milk (15%), full cream packet milk (14%), skimmed milk (8%), double toned packet milk (6%), and token milk (1%). A large difference was observed across the regions with respect to the type of milk purchased. In North, loose buffalo milk (49%) was consumed more whereas in East, cow's milk (65%) consumption was highest. In West, packaged milk was consumed in more quantity (full cream packet milk - 27% and skimmed/light packet milk - 22%) as compared to cow's milk (27%) and in South, single toned packaged milk was purchased more (84%). It was observed that milk has dual usage especially in families with infants between the ages of 0 and 6 months. A specific type of milk was bought for the infant(s). On an average 61% of the infants were given bovine milk. In most cases, loose cow's milk was bought for infants while regular vendor's/packet milk was bought for rest of the family. Both types of milk are processed and stored separately. A regional difference was also observed with the quantity of milk purchased; more quantity of milk was purchased in North (2.3 L) and among SEC A (1.6 L) and least in South (0.74 L) and SEC C (0.98 L) [Table 3]. Most of the families reported consuming the milk on the same day, if any previous day's milk was left it is used for consumption by adults and is never given to infants.

Processing and storage practices: Cow's or buffalo's milk is processed as soon as it reaches home in 93.3% of the cases. On an average 0.8 L of milk is boiled at one time. Dilution of the milk prior to boiling was undertaken by 49% of the mothers. On an average, 144 mL of water is added to the milk (average of 0.8 L). The milk is not covered while boiling in 70% of the cases. The milk is boiled at either moderate (62%) or low (31%) flame. After boiling, the milk is stored in different utensils for infants only if the milk bought is specific for the infants. In most cases, however, the same utensil was used for storing milk for family and infants. As far as storage is concerned, only half of the families store milk in the refrigerator (50.4%), while other families store it openly in the kitchen or rooms (49.6%). As the milk is bought mainly during the daytime, it is stored for an average of 7 h. Post boiling, 45% of the mothers leave the milk in a room/kitchen to bring the temperature of the milk suitable for baby's feed. Only 24% of mothers reported re-heating or re-boiling milk just before feeding the infant [Table 4]. Re-boiling of milk is more frequent in SEC C due to unavailability of a suitable storage system. Also, the milk is heated more in summers and less in winters as milk tends to get spoiled in summers earlier. The utensils are mostly cleaned by boiling in the case of feeder bottle (44%) or rinsed with soap and water (42%). In the remaining cases, the utensils are either rinsed with water only or even used as such.

Consumption behavior: The majority of mothers (62%) reported giving stored milk to their infants whereas the others (38%) gave fresh milk to their infants. No specific trend was noticed in consumption quantity during the day. A mixed use of different utensils is observed for either preparing the feed or feeding the infant. Commonly used utensils for preparing the feed included bowl (34%) and pan (32%) in which the milk is warmed or boiled, followed by a feeder bottle (23%) and a tumbler (12%). However, for feeding the baby, a feeder bottle was used in 58%, a bowl and a spoon in 32% and a tumbler in 10% of the cases [Table 4]. If milk was leftover during a particular feed, it's very unlikely to be given back to infants for a later feed (4.62%); it is either discarded (50%) or consumed by some other family members (43%).

Modification behavior
: The milk is modified in the majority of cases (81%) before being fed. In this study, addition of water was observed before (31%) or during milk treatment (37%) or just before feeding (25%). Modification (addition of supplements) is done depending on the age of infant. Addition of water is more prevalent among mothers of infants between 3 and 6 months. Modification is often done with sugar (85%), followed by water, biscuits, fennel seeds, cardamom or infant cereals before feeding the baby [Table 5]. Among those who add sugar, they are likely to add more than one spoon on an average. Sugar is more likely to be added just before feed. Modifications are done primarily to make the milk easier to digest for infants and sometimes the modification is done for the entire family of the infant is above 9 months of age. The general trend noticed is that the milk packet is washed, or 1 glass of water is added per 1 liter of milk.

Qualitative Assessment

Health care professionals' advice:
It was observed that HCPs do not advise consumption of cow's or buffalo's milk by infants unless there is no other option available. However, the commonly given advice includes:

  • Use pasteurized milk as it is more hygienic than loose milk
  • Milk should be boiled completely. Water and milk should be added in the ratio of 1:3 for young babies (1-2 months), dilution is not required for older babies above 3 months of age.
  • Milk should be cooled down at room temperature and fed with spoon and bowl instead of feeding bottle. Hygiene should be of utmost importance. Clean and sterilized utensils should be used.
  • Previous day's milk or milk kept beyond 24 h should never be given to the baby.
  • Sugar should not be given to infants from birth to 3 months of age, but as the infant grows, quarter to half a spoon of sugar can be added.
  • Milk should be supplemented with vitamins, and sometimes coconut oil or medium chain triglycerides for increasing the nutrient content and calories.


Triggers of adopting cow's/buffalo's milk by mothers: Among mothers, the triggers of initiating cow's or buffalo's milk are varied. These misconceptions mainly relate to mother's milk. The factors range from insufficient lactation to making the infant habitual to drinking milk in future. The triggers for adopting cow's or buffalo's milk by mothers include:

  • Perception of no milk for first 24 h after delivery or insufficient lactation.
  • After long labor, mother is perceived to be too tired to feed baby for some time.
  • Bovine milk considered to be nutritious for the child offering him/her benefits of proteins, vitamins, and calcium. Because of its nutritional benefits, bovine milk has been passed on as the next best substitute for mother's milk from generations, reinforced by family members like mothers or mother-in-laws
  • To make the child habitual to drinking milk in future, hence most mothers start making the child accustomed from beginning itself.
  • Use of milk as a base for other foods or complementary foods.
  • Easy availability, convenience, and cost factor.


Barriers of adopting cow's/buffalo's milk by mothers: Various concerns were also observed among mothers with respect to the usage of cow's or buffalo's milk. Some mothers believe that cow's milk, though thin in consistency (when compared to buffalo's milk), is not easily digested by infants and hence do not approve giving it to their infants. Hygiene is the one of the most important concern associated with cow's or buffalo's milk. Prevailing factors include unclean, unhygienic surroundings of cattle, quality of feed given to the cattle, health of the animal, utensils used for storing milk, leaving milk uncovered in open areas, fear of risk of infestation that would instill infections or any disease to the infants. Also, the adulteration with chemicals or powdered milk in both loose as well as packaged milk is a huge concern. The quality of water used for dilution is another big concern for the mothers.


   Discussion Top


While breastfeeding is recognized to be the best, many children are still fed on cow's or buffalo's milk during infancy. One of the important observations of this study is that across SECs and zones, mothers start feeding cow's or buffalo's milk to their children relatively early in infancy. However, bovine milk contains the nutrients needed for growth and development of the calf, and is a source of lipids, proteins, amino acids, vitamins, and minerals. [6] Concern is often shown for use of cow's or buffalo's milk to very young children. [7] In this study, the HCPs also do not advise cow's or buffalo's milk feeding to children below 1 year of age until no other option is available. Most mothers are unaware of the complications of introduction of cow's or buffalo's milk in infancy. cow's or buffalo's milk has an unbalanced nutrient composition making it unfit for baby's consumption till 1 year of age. Many studies have reported that consumption of cow's milk at an early age does not have much benefits and may lead to iron deficiency as it is a poor source of iron. [7],[8],[9],[10],[11] The cow's milk is high in protein and sodium whereas baby requires less. It contains urea which is not good for infant's health. Also, the trace elements and anti-bodies are absent in cow's or buffalo's milk. [7]

Inappropriate processing and contamination from an unhygienic environment contribute to the development of food-borne pathogens in milk which may adversely affect the health of the infants. [12],[13],[14],[15] Various epidemiological studies have shown that cattle probably become infected through consumption of water and feedstuffs contaminated with feces and other cattle secretions/excretions. These food-borne pathogens can even gain into processing plants and persist in bio-films which can lead to postpasteurization contamination. [12] Other unhygienic practices such as boiling the milk in uncovered containers (70%) or storage of milk outside refrigerator might also have implications in the overall quality of the milk fed to the infants.

In this study, a lot of variation in the storage practices and modification behavior was also observed. For example, dilution of cow's and buffalo's milk before boiling is a common practice which may have health implications as the amount of dilution determines the nutrient content of the milk consumed. Over dilution makes milk too watery and in turn compromises the nutrition profile of the milk. On the other hand, insufficient water dilution may lead to indigestion. Microbial contamination of the milk may also occur depending on the unhygienic household practices and the quality of water used for dilution. Additionally, re-boiling of the milk is an uncommon practice among mothers before feeding the infants. The prevalent practices of modification of milk with the use of supplements such as sugar, fennel seeds, cardamom, etc. might also affect the nutritional/microbial profile of milk. However, the exact evaluation of the same is currently unavailable.

The Infant and Young Child Feeding (IYCF) guidelines states that breastfeeding should be initiated early and exclusive breastfeeding should be continued for the first 6 months of life. It is also mentioned that the most appropriate feeding strategy for infants and young children is that breastfeeding should be continued for up to 2 years and beyond with adequate complementary foods. [16] However, in this study it was observed that doctor's advice consumption of cow's or buffalo's milk by infants if there is no other option available including advice on processing and hygiene. Despite doctors actively advocating best practices to be followed in cow's or buffalo's milk usage, in reality these are not completely adhered to by most mothers. Mothers start giving top feed or complementary foods at their own convenience or as per elders' advice rather than a doctor's recommendation. Breastfeeding is ignored in most of the cases once top feed is started. The cleaning practices and usage of utensils is far from satisfactory as only 44% of the mothers boil the feeder bottles. Sterilization of utensils used to prepare baby feed or of the feeding bottle is not always practiced due to various reasons and is mostly done superficially. Mothers continue to give diluted cow's or buffalo's milk to their babies and dilution is performed as per situation or personal requirement.


   Conclusion Top


The findings of this study indicate a clear gap between recommended and actual practices for infant feeding in India. Although there is a lack of quantitative data on the effect of various household practices on the profile of bovine milk, enough evidence is available on the adverse health implications of feeding bovine milk to the infants. Hence, there is a huge opportunity to educate mothers on the importance of breast feeding and benefits of implementing appropriate processing, storage, and consumption practices of bovine milk.
