| dc.description | Bangladesh is an agricultural country. Bangladesh is also a highly populated country.
Large amount of people depend on agriculture for their livelihood. Poultry sector is one
of the branches of agriculture. Poultry production especially chickens and ducks has
attained an important place in agricultural economy of Bangladesh both through
contribution to GDP and employment especially in urban areas. About 80% of the total
population of 160 million is living in the 68,000 villages of Bangladesh and almost each
and every village home holds 6 to 7 chickens (Samad et al., 2005). From poultry people
get egg, meat which fulfill the protein demand of huge amount of people of Bangladesh.
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. It also brings very short time
return to farmer. According to our socio-economic situation, the knowledge of our
farmer is very little because most of them are not properly trained for broilers
production. There are various Bacterial, Viral, Mycoplasmal, Fungal and Parasitic
disease occurs in broiler, which increase the mortality rate, but unemployed young
generation is coming in this business for short return of value and profit. Pharmaceutical
companies take this advantage. They are convincing farmers for using antibiotics as a
growth promoter or life savings for broiler. As a result, each and every broiler is a depot
of antibiotics. When these broilers are consumed by human this antibiotic residue enters
into human body and causing serious human health hazards with drug residues (Kibria et
al., 2009). With the development and wide use of synthetic and semi-synthetic
antibiotics, pros and cons have been experienced throughout the bacitracin, lincomycin,
penicillin, chlortetracycline and virginiamycin promote growth because of an affects on
the microflora in the gastrointestinal tract. Antimicrobial resistance in zoonotic
enteropathogens including Salmonella, Escherichia coli (E. coli), 50 years, which have
been directed research back to natural antimicrobial products as indispensable resources.
Consequently there is considerable research interest in the possible use of natural
products, such as essential oils and extracts of edible and medicinal plants, herbs and
spices, for the development of new additives in animal feeding. Antibiotics such as and
Enterococci in food animals is of special concern to human health because these bacteria are likely to transfer from the food chain to humans. So, scientists are again
concentrating on the use of our ancient medicinal system to find beneficial herbs and
plants, which can be safely used to increase the production. Such plants, Moringa
oleifera is indigenous plant of Asian subcontinent known for its useful medicinal
properties since ancient times. | en_US |
| dc.description.abstract | Field trial of the study was conducted at the poultry farm and few laboratory tests were
done at Dairy and poultry science laboratory, Hajee Mohammad Danesh Science and
Technology University (HSTU), Dinajpur. The study was carried out a total of 28 days
in order to apply the possibility of treated Moringa oleifera leaf powder in broiler diets to
determine effects of Moringa oleifera leaf on production performance, dressing
percentage (%), quality characteristics and antibacterial effects of broiler. A total of 120,
day old broiler (Cobb 500) chicks were taken and divided into four treatment groups as
T0, T1, T2, T3, each with three replications (10 birds/replication) for each group. Four
dietary treatments were considered: T0 (Control fed with commercial diet), T1
(Commercial diet with 2.5% Moringa oleifera leaf powder), T2 (Commercial diet with
5% Moringa oleifera leaf powder) and T3 (Commercial diet with growth promoter
(Aminosol@ 1ml/L drinking water). The results showed that feed intake was nonsignificant (P>0.05) among the dietary treatment groups. The present study revealed that
Moringa oleifera leaf powder had significant (P<0.05) effect on final live weight, weight
gain and feed conversion ratio (FCR) in broiler. The initial live weight of broiler of
different treatment groups was almost similar. The final live weight (g) was significantly
(P<0.05) higher in T2 (2146.00±88.88), compared to other groups like T1
(2040.00±50.33), T3 (1936.66±43.33) and T0 (1893.33±52.06). The final live weight gain
was found higher in T2 group (2107.33±90.00) where it was 2000.33±50.26,
1897.00±42.17 and 1854.33±52.34 for T1, T3 and T0 respectively. The best feed
conversion ratio was found in T2 group (1.20±0.05) and T1 (1.26±0.03) and the poor FCR
was found in T0 group (1.36±0.05), similar FCR was found in T3 (1.33±0.02). The
dressing percentage (%) in T0, T1, T2 and T3 was 67.82±0.44, 66.62±0.14, 67.25±0.39 and
67.72±0.23 respectively which was non-significant among the groups. However, Moringa
oleifera leaf had effect on antibacterial activity basically against E. coli and Salmonella
and no-significant (P>0.05) effect was observed on Breast weight, Liver weight, Gizzard
weight, Shank weight, Heart weight except Head weight of broiler. The results of the study
suggest that supplementation of Moringa oleifera leaf powder up to level at 5% in diets
has high potential for production performance of broiler. However, further study need to
be taken to understand the active principle(s) of antimicrobial activity and other
beneficial effects of Moringa oleifera leaf powder. | en_US |
