Abstract:
In recent years, the safety of broiler chicken meat consumption is in the forefront of
growing concerns worldwide. However, the broiler chicken farmers spend more expenses
on feedstuffs. Increasing of feed cost has prompted producers to devise strategies to
improve feed using locally available materials. The study aims to develop a broiler
chicken finisher feed by incorporating locally available seaweed (Gracilaria spp.) with
Indian Jujubes’ seed powder as a supplement for the protein. A thirty-five-day feeding
trial was carried out in Trincomalee, Sri Lanka, to determine the performance of broiler
chicken fed with the formulated feed. The finisher diet was formulated to contain 14%
(w/w) of seaweed and 14% (w/w) of Indian Jujubes’ seed powder. One hundred and
fifty (150) broiler chicks of 6 days old (167.68 g) were randomly allocated into five
groups of thirty (30) in each group, and the five feed treatments (T1 Control)-100%
commercial, T2-75% commercial:25% formulated, T3-50% commercial:50% formulated,
T4-25% commercial:75% formulated, T5-100% formulated feed) were assigned to the
groups in a completely randomized design (CRD). Data were recorded and analyzed on
the growth rate, feed consumption rate, and economic value of feed formulation. Daily
body weight gain of birds on formulated diet was not significantly differed (p>0.05)
from birds on a commercial diet. The highest total body weight gain was observed in
T2 at 1370.51±5 g, whereas the lowest was in T5 (1229.44±5 g). The feed conversion
ratio was observed in T2 (1.84), similar to T1 (1.87) in commercial feed. The total
cost for feed (Rs.170.00/kg) is 50% lesser than the commercial feed. The results suggest
that the 25% inclusion level of formulated feed will improve the broiler performance
and cost-effective option. In conclusion, compared to commercial diets, alternative feed
ingredients in broiler finisher feed have enhanced economic efficiency and have beneficial,
long-lasting impacts on growth performance and feed conversion ratio.
