Abstract
Increased demand of goat milk and milk products was due to potential human health benefits. The small size of
fat globules, higher digestibility and less allergic were the reasons of preferred goat milk feeding in infants over cow
milk. Grazing has been the preferred system of goat production, which increases polyunsaturated and conjugated
linoleic acid (CLA) contents of the goat milk. Browsing of polyphenolic rich plant in goats has increased antioxidant
activity and contents of favanoids, gallic acids and diterpens in goat milk. Goat milk fat has a ratio of 5:1 between
omega-6 and omega-3 fatty acids, which is closer to the ratio recommended for the prevention of cardiovascular
diseases in human. Goat milk has the property of minimum changes in fat (fatty acids profile and CLA isomers),
protein and other micronutrient on processing with higher-pressure treatments. The potential therapeutic benefits of
goat milk and milk products consumptions such as anti-carcinogenic, anti-viral properties and the prevention of
cardiovascular diseases have increased growth of goat milk in human intake.

Description
Goat production has constituted an important share of the national
economy in Indian-sub-continent and in many Mediterranean, the
Middle East and European. The world population of goats increased to
a double since 1991, while the numbers of sheep decreased by 7%, and
population of cattle grew by 9%. The growth in the consumption of
goat milk and milk products is due to their beneficial effects on human
health. Goat milk is an excellent source of food and has an acceptable,
attractive odour and taste, and consumed as an alternate of cow milk
because it is less allergenic with higher digestibility. New methods have
developed for increased milk production and cheese quality. The
introduction of plant by-products with secondary metabolites in the
diet of the goats developed new pleasant sensors for the quality control
of new value added products, which have increased preferences of goat
milk consumption [1]. The small size of fat globules and higher
digestibility of goat milk has been the health benefits in infants, and
goat milk has been the preferred food source over the cow milk and
has been better than the mother's milk [2]. Goat milk quality was
established by its potential to tolerate different technological
treatments on order to obtain a product with the level of health
benefits, sensory attributes, safety and nutritive value. The content of
protein and fat, somatic cell counts, bacteriology, immunoglobulins,
inhibitors, freezing point and lipolysis have been other quality
attributes of milk. Goat milk quality can be linked with to the major
physico-chemical component of fat, protein and lactose, and to the
micro compounds minerals, vitamins, cholesterols and terpens.
Protein and fat contents have been important technological attributes
of goat milk quality. The k-casein polymorphism have the interactions
with the changes of αs1-casein, and animals with variants in αs1-casein
produced higher protein and fat contents. The high casein content is
related with higher buffering properties of goat milk. The control of
pathogens determines the quality of goat milk and the somatic cell
counts gave an indirect indication of the presence of pathogens in milk
and established the maximum somatic cell numbers related with the
presence of manor pathogens in milk. Increase of somatic cell counts
in goat milk may cause biochemical modifications and losses of daily
milk production by 15-20 per cent per goat per day.
Recent developments in goat milk production were focused the
control of contaminants, new supplements, sensory enhancement in
milk and milk products [3], and increase in functionality of milk and
milk products [4], all have common aims of improved milk
productivity and quality of milk and milk products for increased their
consumptions. Dietary modification have been employed in goat
feeding in promoting the productivity and quality of milk. Feeding of
goats with polyphenolic rich plant has seen to improve the quality of
milk through increased antioxidant activity with potential therapeutic
benefits of anti-carcinogenic and anti-viral properties. Inclusion of
leaves of aromatic plant in feeding have increased favanoids, gallic
acids, diterpens and polyunsaturated fatty acids content of goat milk
[5]. Administration of source of thyme and other poly phenols in goat
diets have increased milk production, dry matter and lactose content.
Several plant products and fat sources have modified the fatty acid
profile of goat milk with higher contents of unsaturated fatty acids due
to their antioxidant properties by the phenolic constituents and the
presence of high levels of linoleic acid in oil contents. Milk and dairy
products are source of lipid intake in human diet, decrease in
unsaturated fatty acids and increase in omega-3-long chain
polyunsaturated fatty acids, conjugated linoleic acid (CLA) have
recommended due to their potential preventive role in cardiovascular
disease and anti-carcinogenic properties [2]. Goat milk fat has a ratio
of 5:1 between omega-6 and omega-3 fatty acids, whereas a ratio less
than 4:1 or equal have recommended for the prevention of
cardiovascular diseases in human. The modifications of milk fatty acid
profile for improving nutritional quality of goat milk, numerous
alterations of the basal diet were explored. The different lipid
substrates were introduced in goat diets as the most appropriate
procedure for modifying the milk fatty acid profile. Inclusion of less
