Abstract
Aim:
The study was undertaken to find out the gross composition,
nitrogen distribution, and selected mineral content in Surti
goat milk, and its comparison was made between cow and buffalo
milk.
Materials and Methods:
Goat milk samples of Surti breed and buffalo milk samples were
collected during the period from July to January 2014 at
Reproductive Biology Research Unit, Anand Agricultural
University (AAU), Anand. Cow milk samples of Kankrej breed were
collected from Livestock Research Station, AAU, Anand. Samples
were analyzed for gross composition such as total solids (TS),
fat, solid not fat (SNF), protein, lactose, and ash. Samples
were also analyzed for nitrogen distribution such as total
nitrogen (TN), non-casein nitrogen (NCN), non-protein nitrogen (NPN),
and selected minerals content such as calcium, magnesium,
phosphorous, and chloride. Total five replications were carried
out.
Results:
Goat milk had the lowest TS, fat, protein, and lactose content
among all three types of milk studied in the
presentinvestigation. On the other hand, the highest TS, fat,
protein, and lactose content were found in buffalo milk. Buffalo
milk had the highest SNF, calcium, magnesium, and phosphorous
content, which was followed by goat milk and lowest in cow milk.
The SNF, protein, TN, and calcium content of goat milk were
statistically non-significant (p<0.05) with cow milk. The
lactose content of goat milk was significantly lower (p>0.05)
than that of the cow milk as well as buffalo milk. The goat milk
had the highest ash and NCN content, which were followed by
buffalo milk and lowest in cow milk. However,the differences in
ash, NPN, and phosphorous content of three types of milk
studied,
viz.,
goat milk, cow milk, and buffalo milk were found statistically
non-significant (p<0.05). The NCN content of buffalo milk was
statistically non-significant(p<0.05) with cow milk as well as
goat milk. The NCN and magnesium content of goat milk were
significantly higher (p>0.05) than that of the cow milk. The
magnesium content of goat milk was statistically non-significant
(p<0.05) with buffalo milk. The chloride content of goat milk
was significantly higher (p>0.05) than that of the buffalo milk
as well as cow milk.
Conclusion:
It can be concluded from the study that the goat milk has lower
TS, fat, lactose, protein content, TN aswell as NPN but higher
ash and NCN content compared to cow milk and buffalo milk. The
goat milk has lower calcium, phosphorous compared to buffalo
milk while it has higher calcium, phosphorous compared to cow
milk, and it has higher magnesium, chloride content compared to
cow milk and buffalo milk.
