EFFECTS OF GARLIC AND BLACK PEPPER EXTRACT ON BROILERS PRODUCTION

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.
