different level supplementation viz., 0.1, 0.15 and 0.2 per cent in standard starter
and finisher rations on production performance and the economics of broiler
chicken, using one hundred and ninety two commercial day-old broiler chicks for a
period of eight weeks. The birds were divided into four dietary treatment groups
viz., standard broiler ration (T 1), standard broiler ration with 0.1 per cent dried
bovine spleen (T 2), standard broiler ration with 0.15 per cent dried bovine spleen
(T}) and standard broiler ration with 0.2 per cent dried bovine spleen (T4)'
Standard broiler ration was formulated as per BIS (1992) specification for broiler
chicken feed. The observations monitored throughout the experimental period were
body weight gain, feed intake, feed efficiency, protein efficiency and livability. At
the end of the experiment the blood parameters, dressed yield, ready-to-cook yield
and organ weights of gizzard, heart, liver and spleen were also determined. The
results showed that 0.1 per cent dried bovine spleen supplemented groups attained a
higher body weight and 0.15 and 0.2 per cent dried bovine spleen supplemented
groups attained a lower body weight than control but not significantly so. The feed
intake was significantly higher for the standard diet fed group from fifth week
onwards. A positive response was observed in feed efficiency by bovine spleen
supplementation which was statistically significant. Upto six weeks the feed
efficiency was best for the group fed diet supplemented with 0.1 per cent dried
11
bovine spleen, for the eight weeks period 0.2 per cent supplemented group had best
feed efficiency. A significant improvement was noticed in protein efficiency due to
bovine spleen supplementation. The blood values viz., Hb, PCV and ESR did not
show any significant difference among treatments. The dressed yield, ready-to-
cook yield and percentage organ weights were also not influenced by dietary
treatments, but a numerical increase was noticed in ready-to-cook yield. Cost of.
production of broilers in the bovine spleen supplemented groups was lower than
control group and the lowest cost was in the group supplemented with 0.1 per cent
bovine spleen.
Based on the above findings, it can be concluded that bovine spleen
supplementation in low level of 0.1 per cent in standard diet is beneficial in broiler
reanng.
