dc.description | The population growth rate gradually increasing in the world, but do not increasing
landing capacity and proper sources of food. The protein is playing an important role for
human health. To fill up the protein deficiency for big population in the world the
contribution of poultry is mark able. The poultry production systems have led to marked
increase in the production of poultry meat and eggs throughout the world (Armstrong,
1986). It has triggered the discovery and widespread use of a number of “growth
promoters”. The term feed additive is applied in a broad sense, to all products other than
those commonly called feedstuffs, which could be added to the ration with the purpose of
obtaining some special effects (Feltwell and Fox, 1979). The main objective of herbal
plants is to boost animal performance by increasing their growth rate, better-feed
conversion efficiency, greater livability and lowered mortality in poultry birds. These
herbal plants are termed as “growth promoters” and often called as non-nutrient feed
additives (Singh and Panda, 1992). Many synthetic drugs and growth promoters are
supplemented to the broilers to effect rapid growth, but their use have shown many
disadvantages like high cost, adverse side effect on health of birds and long residual
properties etc. Growth promoters are chemical and biological substances, which are
added to livestock food with the aim to improve the growth of chickens in fattening,
improve the utilization of food and in this way realize better production and financial
results. Their mechanism of action varies. Positive effect can be expressed through better
appetite, improved feed conversion, stimulation of the immune system and increased
vitality, regulation of the intestinal micro-flora, etc. In any case, expected results of the
use of these additives are increased financial effects of production. Because of the fact
that growth promoters have different mechanisms of action, it is necessary to present
every group individually and present the effect, which can be expected with their
utilization. With the development and wide use of synthetic and semi-synthetic
antibiotics, pros and cons have been experienced throughout the last 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. | en_US |
dc.description.abstract | This study was conducted to determine the efficacy of garlic, black pepper and GBP
extract as a growth promoter on the performance of broilers. The sixty DOC (Day old
chicks)were divided into four groups, A, B, C and D which were supplemented with
garlic, black pepper and GBP extract @ Iml, Iml and 2ml of broiler ration, respectively.
Weekly observations were recorded for live body weight, weekly gain in weight, weekly
feed consumption, and feed efficiency and blood parameters of birds for six weeks. All
the treatment groups B (1.7+0.062'), C (1.6+58.02°) and D (1.7+63.04°°) recorded
significantly (p<0.01) higher means for live body weight than that of control A
(1.640+58.02) group. All the treatment groups showed non-significant increase in
weekly gain in weight, feed consumption and feed efficiency as compared to that of
control group. In Bangladesh broilers production is mainly performed by non-technical
farmers. The broiler production demand is very high because it supports short return of
money but major problem is cost maintenance. The initial body weight of group (A), (B),
(C) and (D) on 7" of this experiment were 144+7.30gm, 145+7.30gm, 140+7.30gm and
141+7.30gm respectively and after 42nd day of experiment final body weight were
1600+58.02gm, 1700+63.04**gm, 1640+58.02gm and 1730+63.04*gm respectively.
The net body weight gain were 1.6+58.02gm, 1.7+63.04**gm, 1.64+58.02gm and
1.73463.04*gm respectively and economics of production were analyzed and found that
net profit per broiler was 38Tk, 45.4Tk, 40.96Tk and 51.16Tk respectively. It is
concluded that broiler produced by using herbal extract may be profitable and suitable
for human consumption. | en_US |
