Abstract/ Executive Summary:

A total of 144, day old as hatched Cobb-500 broilers were fed adlibitum basis on a diet with 0%, 0.5%, 1.0% and 1.5% of Black Cumin Seed Meal up to 35 days of age to compare the effect of BCSM as herbal growth promoters on growth performance, meat yield characteristics and profitability of broilers. The experimental diets consisted of broiler starter and broiler grower, which were fed from 0-16 and 17-35 days of age, respectively. Diets supplemented with 1.5% BCSM showed significant effect on live weight at 21, 28 and 35 days of old in broilers in various groups as compared to that of control group. Better feed conversion (2.02) also noticed at 1.5% level of BCSM at early stage (14 days of old) of broilers. There was no significant difference (P>0.05) among the average live weight, dressing yield, thigh meat, wing meat, heart, gizzard liver, at 0%, 0.5%, 1.0% and 1.5% level of BCSM diet. But difference found within breast meat, drumstick meat, abdominal fat and skin of broilers at 1.5% level of BCSM diet. It may be concluded that supplementation of BCSM at 1.5% had the highest significant effect (P<0.01) on feed cost (Tk kg^-1 b), production cost (Tk kg^-1 b) and profit (Tk kg^-1 b) and lower mortality. So that 1.5% BCSM in diets can be used for economic and efficient broiler production than 0.5% and 1.0 % level.

Objectives:

To assess the effect of BC seeds on broiler performance and survivability at different inclusion level and economic use of BC in broiler.

Methodology:

This study was carried out with 144 day old as hatched Cobb 500 broilers for a period of 35 days at Bangladesh Agricultural University (BAU) Poultry Farm, Mymensingh to find out the effect of dietary levels of black cumin seed meal (BCSM) on feed consumption, weight gain, FCR, mortality, cost of production of BCSM in diet formulation to maximize the performance of broilers. Day old broilers (Cobb 500) were purchased from a commercial hatchery “Nourish Poultry and Hatchery Ltd” of Shreepur, Gazipur and black cumin was purchased from local market, Mymensingh. A total of 144 day old broilers were randomly distributed to 4 dietary groups each having 4 replications. The treatment groups were having 0%, 0.5%, 1% and 1.5% BCSM. There were 9 chicks in each replication. Locally available ingredients were used to formulate ration for the broilers. The diets were prepared by hand mixing. All ingredients except BCSM were purchased from the local market of Mymensingh town. Major ingredients were thoroughly mixed at first and then micro-ingredients. The diets were prepared with 4 different levels of BCSM (0%, 0.5%, 1% and 1.5%). Broilers were fed two diets, starter (0-14 days) and grower (15-35 days). Ration formulated according to the standard nutrient requirement of Cobb 500 individual strain recommended by BSTI. The nutrient percentage in prepared starter and grower ration were showed in the. The experimental rooms was properly cleaned and disinfected first by phenyl solution later with vircon S. After drying, the experimental house was divided into 16 equal sized pens, separated by bamboo materials and wire net partitions according to treatments and replications. Pen and wire net partitions were disinfected by phenyl solution after cleaning and washing. The experiment was conducted in a gable type open sided tin-shed house. The proper management procedures were followed during experimental period and identical management practices were maintained. The house was partitioned into 16 pens using wire-net (90 cm height) where a group of 9 broilers were randomly allocated to each pen. Floor space for each broiler was 900 cm² for comfort ability of broilers during summer. One trough (90 cm × 11.5 cm ×6 cm) feeder and one pot drinker with a capacity of one litter were provided in each pen up to 35 days. Feeders were cleaned every week and drinkers were cleaned every morning. Fresh clean drinking water was provided twice daily up to 35 days. Just after arrival, chicks were supplied with a solution containing glucose, electrolytes. Saw dust was used as litter at a depth of 5 cm. After third week previous litter was replaced by new dry saw dust. Every two days interval litter was stirred to prevent ammonia gas and maggot formation. All of the experimental broilers were vaccinated against New Castle disease and Infectious Bursal Disease at the age of day 5^th and 12^th respectively. All the vaccines were administered as per recommendation of the manufacturer. Temperature was maintained at 30⁰C as brooding temperature which was decreased gradually in subsequent weeks @ 2.5⁰C/week until the broilers were adjusted to environmental temperature. Each pen was provided two electric bulbs (100 wt). Broilers were exposed to 24 hours continuous light in first 7 days. Strict bio-security measures were taken during the experimental period. Entrance of personnel was restricted. Before entrance, shoes were changed and feet were dipped in a footbath containing disinfectant solution (potassium permanganate) and the footbath was at the entrance point of the experimental house. No birds died during the entire experimental period. During dressing the following parameters were recorded; live weight, blood weight, feather weight, head weight, dressed weight, abdominal fat, viscera weight, liver weight, drumstick weight, heart weight and skin weight. The following records were kept throughout the experimental period; body weight, body weight gain, feed consumption, feed conversion ratio (FCR), mortality, production cost and profitability, records of dressing yield and dressing percentage. Records were kept for each week. Analysis of Variance (ANOVA) was performed to compare growth performance, profitability and meat yield parameters. A SAS system was used for analysis of all data and all significant and non-significant effects were identified by Ducan’s Multiple Range Test.

Achievement/Findings:

Based on the above findings, it has been concluded that black cumin seed meal can be included at 1.5% level in the broiler diet as natural growth promoter for broiler to improve feed conversion ratio, carcass yield and survivability.
