Abstract
ABSTRACT:
A study was conducted to evaluate the nutritive value and
utilization of palm kernel (Elaeis guineensis) meal on the performance
of commercial egg type birds during chick and grower phases. Palm
kernel meal (PKM) contained 14.1,1.7,16.2,4.1 and 63.9 per cent crude
protein, ether extract, crude fibre, total ash and nitrogen free extract
respectively on dry matter basis and 1986 kcal/kg of metabolizable
energy.
Five experimental diets were formulated using palm kernel meal
at 0, 3.5, 7, 10.5 and 14.0% during chick and 0, 10.5,21, 31.5 and 42%
during grower phases to replace de-oiled rice bran at 0, 25, 50, 75 and
100% respectively. Each experimental diet was tested with 40 layer
chicks and the total number of birds used in the experiment was 200.
The experiment was carried out for 20 weeks.
The body weight gain was significantly (P<0.01) different in
chicks and growers, although better weight gain was noticed in the
groups fed the diet containing palm kernel meal at 7.0(C3) and
2 1 .0(G3) per cent levels during chick and grower phases respectively.
The feed intake was significantly (P<0.0 1) increased in birds fed
different experimental diets during the chick and grower phases. It was
the highest in chicks fed rations containing 14(C5) and 42(G5) per cent
palm kernel meal during chick and grower phases respectively.
The feed efficiency was significantly (P<0.0 1 ) reduced during
chick phase at all levels of palm kernel meal inclusion whereas during
grower phase it was comparable among treatments except in birds fed
rations containing 21%(G3) , in which it was significantly (P<0.01)
better than in other treatments.
The feed cost during chick phase was significantly (Pc0.01)
higher in birds fed palm kernel meal containing rations(C2- C5) than in
C1 fed birds; whereas during grower phase it was lower (PC0.01) in
birds fed with GZ,G 3,G 4a nd GSt han GId iet.
Inclusion of palm kernel meal at different levels had no
significant effect on first egg weight, age at first egg and hen - day egg
production and also on serum alkaline phosphatase levels in
commercial layer birds during chick and grower phases. Two birds
died during growing phase and the cause of death was not related to
dietary treatments.
It is inferred that palm kernel meal could be incorporated upto
7 and 42 per cent during chick and grower phases respectively to
replace DORB without affecting the performance of commercial egg
type birds.
