study was conducted to compare meat quality of the chicks and adoption pattern
(behavior) between surrogate mother and offspring raised under scavenging and
intensive system during April-August 2003 at IAAS Livestock Farm,
Chitwan,
Nepal. For the
scavenging management system, four adult local hens (Sakani) known for better
broody characteristics and two female adult Muscovy ducks were purchased from
the local villages, and ninety-day-old Cobb-100 commercial chicks from a
hatchery. Then 4 hens were provided with 10 commercial chicks each at the 21st
day of her brooding stage; similarly, two female ducks were provided with 10
commercial chickens each at the 28th day of their brooding stage. The
dams (4 hens and 2 female ducks) were offered day old commercial chicks (10
each) to remain as their progeny and then allowed to be as family. Their
behavioral pattern of adoption was studied from beginning to 12th
week. The meat quality was analyzed through orgnoleptic test. It was found that
the meat quality of broiler raised under scavenging system was superior in terms
of taste, juiciness, tenderness, flavor and general appearance. This was due to
free consumption of natural food and free movement that reduced abdominal fat
deposition and unwanted fowl smell accumulation. However, the average weight of
dressed meat of chicks under intensive regime was higher than scavenging regime.
Similarly, dressing percent of meat under intensive was also higher. Regarding
behavioral study under scavenging regime, both hen and chicks showed positive
response towards each other. Although the duck were reluctant to accept the
chicks initially, both surrogate hen and duck started to respond positively
towards chicks later on. The chicks also responded positively to their surrogate
mothers indicating that the hen responded better than ducks for rearing chicks
as surrogate mother. The chicks reared under scavenging (both hen and duck) were
appeared to be remarkably profitable in terms of net benefit than the chicks
reared under intensive. It was concluded that this practice would be viable
especially in rural areas to rural poor, where there is no electricity for
brooding and where there is no feed supply system.
