Abstract/ Executive Summary:

The experiment was conducted with 108 day old straight-run Hubbard Classic broiler chicks for a period of 35 days to investigate the effects of citric acid, commercial herbal additive (Keqinling) and their combination on growth and carcass traits of broiler. The dietary treatments were control (T₀), 0.5% citric acid (T₁), 0.2% Keqinling (T₂) and combination of 0.5% citric acid +0.2% Keqinling (T₃). Final live weight was 1615, 1710, 1707 and 1795g in control, 0.5% citric acid, 0.2% Keqinling and their combination groups respectively. The highest live weight gain (1748g) was found in combination group followed by 0.5% citric acid (1664g), 0.2% Keqinling (1660g) , and the lowest (1568g) in control group. The highest feed consumption and feed conversion efficiency was observed in T₃ and the lowest in group T₀. Significantly (p<0.05) the highest dressed yield (%) was found in 0.5% citric acid group (56.65) than combination (55.73) and Keqinling (55.18) and lowest in control group (54.59). Citric acid reduced the pH of the both feed and faces. The cost of production (Tk/kg broiler) was lowest in citric acid group (Tk. 76.22). Net profit per broiler production was found in 0.5% citric acid group (Tk. 10.03/broiler) followed by combination (Tk. 9.28), Keqinling (Tk. 7.31) and control group (Tk. 6.98) respectively. The addition of 0.5% citric acid and 0.2% Keqinling individually or their combination increase the performance of broiler but citric acid showed better response than Keqinling.

Objectives:

To investigate the effect of citric acid, herbal feed additive (Keqinling) and their combination on the performance of broiler and to determine the economic competence of using citric acids or Keqinling and/ or their combination.

Methodology:

The research work was carried out in the poultry rearing unit of Shahjalal Animal Nutrition Field Laboratory of the Department of Animal Nutrition, Bangladesh Agricultural University, Mymensingh. There were two test substances used in this study such as citric acid and Keqinling. Citric acid is an organic acid purchased from the local market in Mymensingh and Keqinling, a natural feed additive of herbal extract produced by Guangdong VTR Bio-tech Co. Ltd. China and marketed by Advance Animal Science Co. Ltd. from where it was collected. One hundred and eight day-old straight-run broiler chicks (Hubbard classic) were used for this experiment. The chicks were purchased from Aftab Bahumukhi Farms Ltd., Bhagalpur, Bajitpur, Kishoregonj. All birds were reared in the cages maintaining similar environment. Day old chicks were randomly divided into 4 equal groups with 3 replications each having 9 broilers (27 broilers per treatments). The four dietary treatments were control (T₀), 0.5% citric acid (T₁), 0.2% Keqinling (T₂) and their combination 0.5% citric acid + 0.2% keqinling (T₃ The experimental house, cages were properly cleaned and washed by forced water using a hose-pipe and then disinfected by bleaching powder and Virkon S solution (50 ppm). At the same time, all feeders, plastic buckets, waterers and other necessary equipment’s were properly cleaned, washed and disinfected with bleaching powder solution subsequently dried and left them empty for a week before the arrival of chicks. After arrival of chicks in the experimental house, they were supplied adequate glucose solution to prevent transport stress and dehydration. Proper light, temperature and ventilation were maintained. Previously prepared mash feed was supplied treatment - wise twice a day (7.00 am and 5.00 pm) on adlibitum basis. Fresh, clean drinking water was made available all the time. In each cage, one feeder and one round water were provided for supplying feed and water. The experimental birds were vaccinated against Infectious Bursal Disease (IBD) and Newcastle Disease (ND). Vaccines were administrated as per recommendation of the manufacturer. Birds for each treatment were weighed by using electric balance in a group during onset of the trial and then every week at the age of 7, 14, 21, 28, 35 days. Feed offered was recorded when supplied in cages and refusal at the end of each week. Feed intake, feed conversion efficiency and feed conversion ratio was calculated. After 35 days of trial, three birds from each treatment were slaughtered to find out the dressing yield. The cost of broiler production for each treatment group was calculated based on the market price of feed ingredients, cost of chicks, citric acid and keqinling and management cost. Samples of diets were analyzed to determine dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE) and total ash following the method of AOAC (1990). Calculated from Wiseman (1987); CA= Citric acid; K= Keqinling Data were analyzed using statistical SPSS (11.5) program fo r one way ANOVA . DMRT (Duncan 1955) was done to know the difference among the treatment means according to Steel and Torrie (1980).

Achievement/Findings:

The addition of 0.5% citric acid and 0.2% Keqinling individually or their combination increase the performance of broiler but citric acid showed better response than Keqinling. Although citric acid and Keqinling have synergistic effect on the performance of broiler but economic study suggests the dietary inclusion of citric acid at 0.5% level in Bangladesh condition.
