Effect of partial mango pulp mixing in ration on behaviour and production of broiler

Abstract

The present study was carried out to investigate the effect of various levels of mango pulp ration on the
growth, carcass and behavior of broiler during the year 2010 to 11. The experiment enrolled 200 one day old
chicks and randomly divided them into four groups i.e. A, B, C and D groups were fed during 1st, 2nd and 3rd
weeks, later group A was not fed and kept as control beside others were fed a ration mixed with Mango
pulp as supplement at the rate of 2, 3 and 4% per kg, respectively. Mango pulp contained DM 97.5% and CP
12, Fiber 3.5 and Ash 2.5 percent on DM basis. All feeds were iso-nitrogenous and iso-caloric offered twice
a day and fresh water was made available over 24 hours thrice a day. At the end of the experiment, the
average of the liver weight in B (51.98) was higher than C (45.03), D (43.58) and A (40.71) g/b (P<0.05) and
gizzard weight was higher in group A (36.2) than D (34.58), C (31.8) and B (29.97) g/b, (P<0.05) but in the
hearts weight were found not significant differences (P>0.05) between group A (10.68), B (10.70), C (11.86)
and D (10.16) g/b, (P>0.05), respectively. RBC’s (2.60, 3.13, 2.03 and 1.97, m/ cu.mm), WBC’s (3933, 4500,
3450 and 3383, 000/ mm3) and Haemoglobulin values (9.0, 10.7, 6.5 and 5.5 g) were not different for groups
(A, B, C and D (P>0.05), respectively. Feeding, drinking, standing/walking and lying/sleeping behavior were
not significant differences (P>0.05) between the groups for periods of brooding and growing (P>0.05),
respectively, but generally all these behaviors were higher at brooding than growing periods (P<0.05),
respectively. It was concluded that mango pulp at a level of 2 percent had a better impact on both broiler
body and carcass weights and FCR with no health problem in broilers.
