 Gross composition
 Poultry meat is highly nutritious food for human beings
 Similar to eggs poultry meat is also a low calorie food
 A concentrated food highly suitable for all age groups and
for all season
 The gross chemical composition of poultry meat is highly
variable depending on the age and type of birds as well as
their diet and environment under which they are reared

5. Proteins and Amino acids
 Poultry meat contains more protein as well as more amino
acids than other meats
 Poultry meat proteins are of high BV ( Biological value)
 The biological value of poultry meat varies inversely with its
collagen content
 Meat from Older birds is of low biological value than from
younger birds
 BV Value of poultry birds varies from 65-85

7. Lipids
 Lipid content is the most variable in the poultry meat
 It depends on sex ,Age, Species , Diet,
 The fat of poultry meat is mainly subcutaneous
 Poultry meat contains higher proportion of unsaturated
fatty acids than From other meats
 About 50 % of the Unsaturated fatty acids, containing 18
carbons, is linoleic acid (LA)
 The cholesterol content of poultry meat is quite low
 Chicken breast meat contains 79 mg whereas ,Drumstick
meat has 91 mg
 Chicken fat has 65 mg per 100g

10. Minerals and vitamins
 Poultry meat is an excellent source of minerals and
vitamins
 It supplies good amount of phosphorous and iron
 Iron in meat is not only highly available, but also increases
the availability of Iron from other sources.
 Meat being predominantly skeletal muscle, is very rich in
potassium (intercellular ion)
 Meat is the best source of niacin and is a good source of
riboflavin
 The organic meat (Liver ) is an excellent source of Vitamin
A,B2, and Niacin

12. 100 g of Organ meat
 Consumption of 100 g of Organ meat especially Liver,
 Supplies seven times the requirement of vitamin A
 14% of the requirement of vitamin B1.
 11/2 times the requirement of vitamin B2
 ¾ th of the requirement of Niacin
 1/3rd the requirement of Vitamin C

13. Factors affecting the Composition
 Diet
 Sex
 Age

14. Diet
 Diet can have significant effect on composition
 Feeds containing higher proportion of Fat/High calorie-protein
ratio tend to increase carcass fat
 Broilers growing at high ambient temperature also tend to deposit
more fat
 Force feeding geese increases weights of liver due to excessive
deposition of fat
 Fatty liver also noticed in caged layers
 Fatty acid composition of turkey fat is considerably influenced by
composition of dietary fat
 In case of chicken, Dietary fat influences the fatty acid
composition of thigh meat and abdominal fat

15. Sex
 Fat content in males is usually lower than that in females
in both chicken and turkey
 Females tend to deposit more fat Mute oestrogens
 Male broiler meat contained more riboflavin and sodium
than that of females.

16. Age
 Fat deposition, Niacin and Thiamine increase with age in
case of broilers with concomitant reduction in moisture
and riboflavin.
 In case of Turkey ,Cooked edible yield increases with Age

17. Ratites

18. Ratites
 Ratites (ostriches, emus, rheas) have received increasing
attention as meat producing animals.
 Carcass and meat yield The carcass yields of ostriches and
rheas are presented in Table 1.
 The dressing percentage of rheas (carcass weight as a
percentage of live weight) is of the same order as for
ostriches.
 The wings and head of the rhea comprise more of the bird
than in the ostrich, while the skin represents a smaller
percentage of the live weight

20. Meat Characteristics
 The red colour of ratite meat can be partly explained by
the high pigment content - 26 and 22-30 pg Fe/g for emu
and ostrich meat, respectively (Berge et al., 1997; Naudk
et al., 1979)
 Depending on the particular muscle, in ostrich carcasses
(Sales and Mellett, 1996) the final pH was reached 2-6
hours after bleeding while in rhea carcasses (Sales et al.,
1997b) the final pH was reached 30 minutes to 6 hours
after bleeding.

21. Nutritive value
 In the study by Sales (1996) intramuscular fat content was determined by
petroleum ether extraction, while Berge et al. (1997) determined the total lipid
content by methanol-chloroform extraction.
 According to Berge et al. (1997) the moisture, protein and lipid contents did not
differ much between five different emu muscles,
 Sales (1996) found a wide range of values for moisture, protein and fat content
between 11 different ostrich muscles.
 Variations in collagen content between muscles have been recorded for both
ostriches (Sales, 1996) and emus (Berge et al., 1997).
 For some of the most important nutrients Table 6 compares the meat from
ostriches, emus, rheas and chickens.

23. Emu meat

24. Quail

25. Quail meat
 Japanese quail (Coturnix coturnix japonica), a small
domesticated avian species, has assumed importance
worldwide as a laboratory animal and is also commercially
exploited for meat and egg production. (Wilson et al.,
1961)
 Panda et al. (1987) found 5 weeks to be the ideal
slaughter age for both male and female quail from the
viewpoints of high economic return and meat palatability.
At this age average live weight (mixed sexes) was 140 g
with a feed conversion ratio of 3.0.

26. Nutrient composition of meat
 Quail meat is considered a table delicacy.
 The composite thigh and breast raw meat samples from adult Bobwhite
quail contain 74.1% moisture, 22.1% protein and 3.0% fat (Dawson et al.,
1971b).
 In a comparative study on the nutrient composition of meat from Japanese
quail, pen-grown and wild Bobwhite quail, Hamm and Ang (1982) reported
that the meats from all these types of quail were excellent sources of
pyridoxine (0.52-0.68 mg/100 g), Niacin (6.0-10.3 mg/100 g)
 were good sources of Thiamine (0.10-0.17 mg/100 g), Riboflavin (0.16-
0.50 mg/100 g), Pantothenic acid (0.66-1.0 mg/100 g),
 minerals and essential fatty acids (Table 7).
