Description The name Guinea fowl is derived from the Guinea coast of Africa from where
the birds are believed to have originated. This bird was brought to India by African
slaves during medieval period. It can be kept both for meat as well as egg production.
Body weight is regarded as a function of framework or size of the animal and its
condition. Variation in body weight within a flock can be attributed to genetic variation
and environmental factors that impinge on individuals. As per current demand of the
guinea fowl in country; the present study was undertaken at CPDO(ER), Bhubaneswar
with objectives to study the mean live body weight, to evaluate the correlations between
juvenile body weight and to find out the sexual dimorphisim at different ages and to set
up the data base on live body weight to help guinea fowl farmers and breeders.
Combined sex mean hatch weight of lavender, pearl and white verity guinea fowl were
21.86±7.92, 22.47±8.12 and 21.86±0.59 g respectively. The 4th week body weights were
210.06±4.70, 209.91±4.93 and 185.50±21.65 g respectively. The 8th week body weights
were recorded as 594.38±17.29, 596.51±15.85 and 505.79±63.87 g for lavender, pearl
and white respectively. The 12th, 16th and 20th week body weights were 970.31±28.13,
1218.30±37.62 and 1412.41±42.58g for lavender; 873.01±25.60, 1155.94±37.64 and
1320.19±38.58 g for pearl and 726.78±94.62, 1004.39±120.30 and 1264.17±147.27 g for
white guinea fowl respectively. A sexual dimorphism between male and female was
observed with a significant different at all ages. Correlations between body weights at
different ages for lavender male, female and combined sexes were varied from 0.035-
0.671, 0.013-0.772 and 0.121-0.808 in respectively. The magnitudes for pearl were
varied from 0.006-0.657, 0.022-0.835 and 0.022-0.845 respectively. The corresponding
values were 0.078-0.790, 0.112-0.755 and 0.120-0.823 for white respectively. The
lavender combined sex body weight gain during 0-4, 4-8, 8-12, 12-16 and 16-20 week of
age were recorded as 188.87, 384.86, 375.55, 247.00 and 194.11 g respectively. The
corresponding values were 188.08, 387.64, 273.36, 284.20 and 164.25 g for pearl variety
respectively. The white variety four weekly gain reports were recorded as 163.65,
317.50, 220.10, 266.55 and 269.35 g during 0-4, 4-8, 8-12, 12-16 and 16-20 week of age
respectively. Sexual dimorphisim was noticed at all age groups and all three varieties.
The great variation between different ages and genotypes indicates that there is
potentiality in the population for future research.
