Abstract
A study was carried out to investigate the effect of copper sulphate on the performance
of broilers. A total number of 144 day-07 old chicks were randomly divided into four
dietary treatment groups having 3 replications containing 12 birds in each replication
among which four dietary group were considered: T0 (Basal diet with no supplemental
CuSO4); T1 (Control + CuSO4 @ 100 mg/Kg feed); T2 (Control + CuSO4 @ 175 mg/Kg
feed) and T3 (Control + CuSO4 @ 250 mg/Kg feed) respectively. Data on live weight and
feed intake were collected and finally three birds from each replication were randomly
selected and slaughtered for measuring carcass characteristics at 35 days of experimental
periods. By using the SPSS software the collected data were analyzed at 5% level of
significance. Total feed intake were non-significant (P>0.05) among the treatment
groups but final live weight, live weight gain and FCR were significantly differed among
the treatment groups. Significantly (P<0.05) higher body weight gain was found in T2
(2501.25±34.95) which was followed by T1 (2424.74 ±39.97) compared to T4
(2367.11±28.4) and T0 (2355.89±42.7) group respectively. The best and lowest FCR was
found in T2 (1.40±0.022) than T0 (1.49± 0.03) while FCR in T1 and T4 group was
1.45±0.062 and 1.48± 0.23 respectively. In the present study, it was found that copper
sulphate had significant (P<0.05) effect on dressing %, abdominal fat weight (g) and
gizard weight (g) but no significant (P>0.05) effect on heart weight (g) and liver weight
(g). The load of E. coli and Salmonella sp. was counted from the sample of intestine,
cloaca and caeca of 35 days aged broiler. The E. coli and Salmonella sp. load in
intestine, cloaca and caeca was significantly decreased in CuSO4 treatment groups
compared to control group. Cost effective analysis of the present study revealed that net
Profit/ broiler (Taka) was significantly highest in T2 (51.86±3.72) which was followed
by T1 (42.62±4.34), T3 (36.23±4.18) and T0 (36.06±4.59) respectively. As comparing all
the parameters, CuSO4 @ 175 mg/Kg feed can be added in commercial broiler diet for
profitable broiler production.
Description
Bangladesh is a country with over population and growth of population is increasing
very fast day by day in comparison to its land size, as a result huge pressure is created on
people’s basic need. Demand of protein of this booming population is a great threat for
us. It is evident that a substantial majority of the population suffers from varying degrees
of malnutrition, including protein-energy malnutrition, micro-nutrient deficiencies,
iodine deficiency disorder, iron deficiency, anemia, and vitamin deficiencies (Sorwar et
al., 2016). There are so many sources of protein but it is not possible to fulfill the
demand without broiler. Because the duration of broiler rearing is very short and within
36-42 days it is ready for marketing and suitable for human consumption (Kamal et al.,
2015).
