A study was conducted to determine the effect of feeding different levels of
Leucaena leucocephala (Ipil-ipil)
leaf meal (LLM) inclusion on growth, feed consumption, feed efficiency, and cost
of different rations of Vencobb broiler at Livestock Farm, IAAS,
from 5 April to 16 May 2005. Two hundred, day-old straight-run chicks
from same hatchery were brooded for a period of seven days, feeding
pre-experimental diet. On 8th day, chicks having uniform body weight
were leg banded and randomly allocated into five dietary treatments with four
replications (10 chicks/replication) in CRD. The isoproteinous and isocaloric
formulated standard starter (CP 22.3%; ME 3036 Kcal/kg) and finisher (CP 20%; ME
3204.7 Kcal/kg) diets were supplemented with LLM in different levels, i.e. T1
– 0.0%; T2 – 2.5%; T3 – 5%; T4 – 7.5%; and T5
– 10%, respectively. The chicks were offered
ad libitum broiler starter and
finisher diets from 8-21 and 22-49 days, respectively, and clean drinking water
was provided as necessary. The uniform management practices were performed
throughout the investigation period. The data were recorded weekly and analyzed
using MSTATC. Feed cost of different experimental diets was also calculated The
results revealed that inclusion of LLM on average live body weight (gm) of
different dietary groups differed significantly (P<0.05); the highest average
live body weight (2091.3+16.3 gm/chick) was in the group on diet
supplemented with 5% LLM and the lowest (1961+16.3 gm/chick) in the group
on diet having 10% LLM, the diets having 5% LLM was significantly higher than
that of groups on diet having 7.5 and 10% LLM. Average live weight gain (gm) did
not differ significantly (P>0.05); however, the highest weight gain (493.6+17.6
gm/chick) and the lowest (385.0+17.6 gm/chick) were obtained in the group
on diet having 5% and 7.5% LLM, respectively, while verage feed consumption (gm)
of different dietary groups differed significantly (p<0.05); the highest feed
consumption (1136.4+21.17) was in the group on diet having 10% LLM, and
the lowest (978.6+21.17) in the group on diet with no LLM, the groups on
diets having 5% and 10% LLM resulted significantly higher weight than that of
0.0% LLM. Over all average feed efficiency of different groups of birds did not
differ significantly; while the highest feed efficiency (3.6+0.27) was
recorded in the group on diet containing 7.5% LLM, and the lowest (2.14+0.27)
in the groups on 0.0% LLM. The price of rations per kilogram in NRs. was the
lowest (17.16/chick) in the group on diet having 10% LLM. As the inclusion rate
of LLM was increased the price of feeds was decreased, and it can be concluded
that broiler chicks can be raised safely up to 5% inclusion of LLM in diets.
