Abstract:
Milk is an important food because of their high nutritional value for public health. Biochemical methods were used for the examination of the quality of milk but lack the study in lactation stages. In the present study, raw milk samples (n=3) from mammalian species i.e Cow, Buffalo, Goat, and Human were collected and analyzed for protein and fat determination during successive lactation days. The presence of fat and protein percentage determination was evaluated by the Gerber method and formal titration method respectively. The percentage of protein and fat ratio in each mammal were considered during their lactation days. The study shows the protein content of cow milk (5.85%) is higher at 11th day of lactation than in Buffalo, goat and human milk, but it is low in human milk (1.0%) at 150th day as compared with buffalo, goat, and cow milk. Among these samples, Cow milk had the highest protein content during the early stage. The fat content (6.5%) in buffalo milk at the 3rd day of lactation is higher than other milk, while fat content (2.5%) is lower in cow milk at 150th day of lactation than in human, goat, and buffalo milk. The result indicated that analyzed milk through entire lactation states could contribute a marker for highly nutritional value based on their milk profile. This study put forward that milk composition is largely a function related to maternal nutrient intake by infants and duration of milk production. Conclusions were made possible by including the markable variation in biochemical components mainly fat and protein among species at different lactation stages.
