Abstract/ Executive Summary:

The performance and profitability of three commercial broiler strains reared under farming system were investigated in this study. Day-old broiler chicks (n=156) of three different commercial strains (Hubbard classic, Cobb-500 and MPK) were assigned to three treatment groups in a completely randomized block design, each treatment replicated four times, 13 birds per replicate. The birds were reared from d1 to 35 days of age with similar housing, feeding and environmental management condition. Regarding to all parameters collected, live weight and body weight gain were higher (P<0.001) in T2 (Cobb-500) group, while the birds of T3 (MPK) group were the lowest. Birds of T1 (Hubbard Classic) and T2 (Cobb-500) strain group consumed higher (P<0.001) feeds, while the birds of T3 (MPK) had the lowest feed intake. Cobb-500 broiler strain achieved superior (P<0.001) FCR, while the birds of T1 (Hubbard classic) strain group had poorer FCR. Liveability of the broiler strains was unaffected by all the treatment groups. Higher net profit and lower production cost observed in T2 (Cobb-500) group than those of other strains, although the difference between the treatment groups was similar. The highly significant measurements of live body weight, weight gain and better FCR values were recorded for Cobb-500 broiler strain, followed by Hubbard classic and MPK, respectively. In conclusion, Cobb-500 broiler strain is appeared to be the most economic to rear amongst the three broiler strains investigated here in response to their performance records.

Objectives:

The present study was undertaken to compare the performances and economic suitability of three commercial broiler strains (Hubbard classic, Cobb-500 and MPK) reared under the farming condition in Bangladesh.

Methodology:

A total of 156 day-old broiler chicks (either sex) were collected from the purchasing outlets of three different breeding hatcheries in Bangladesh. The chicks were randomly allocated into three treatment groups (T1, T2 & T3) having 52 chicks in each group. Each treatment had four replications of 13 birds. Three broiler strains such as Hubbard classic, Cobb-500 and MPK were collected from the different purchasing outlets located at different places in Bangladesh. The birds were reared at the broiler farm in Magura district, Bangladesh from 31 to 35 in the year of 2008. A total of 12 floor-pens of equal size were set up in an open-sided house to accommodate the birds from d 1 to 35 days. Each pen contained a feeder and a drinker for proper feeding and drinking. Litter of wood shaving materials to a depth of 2 cm was spread on the floor of each pen to maintain a comfortable environment for the birds. Feeders were cleaned daily before supplying diets, and drinkers were washed weekly to maintain hygienic condition for the birds. The birds were brooded with a temperature of 35^oC for the first two days only, and then this was reduced by 1 or 2^oC every 1 or 2 days until day 19, when the temperature was set at 24^oC and this temperature was maintained until the end of the trial period.Continuous lighting was provided throughout the trial period. Feeds were provided in a pellet form. Birds had free access to water and feed which were provided adlibitum throughout the trial period. Commercial ready-made compound broiler feeds (pellet) were supplied the birds adlibitum throughout the trial period. The feeds were collected from the purchasing outlets of the Aftab Bohumukhi feed mill company. Birds were fed the starter diets from 0 to 21 days, and the finisher diets were used for the rest of the trial period (22 to 35 days). The nutrient composition of the experimental feed was shown in Table 1. The nutrient composition of the experimental feeds used in this study appeared to be a bit different from the recommended levels prescribed by NRC (1994) for the broiler chickens. All the birds received the necessary vaccines against Newcastle disease, Infectious Bursal diseases and Infectious Bronchitis disease and medicines for disease protection. All dead birds were sent to the Veterinary Hospital of Chittagong Veterinary & Animal Sciences University, Chittagong, for postmortem examination to identify the causes of death. Data collection Birds were weighed individually before allocating them into the pens, then in group wise on 15, 23, 28 and 35 days of age to the end of trial. Live body weight (LBW) and feed intake were recorded on the same days. Mortality was recorded daily, while body weight and feed intake were recorded on 15, 23, 28 and 35 days of age for the calculation of body weight gain, and FCR corrected for mortality. Mortality of birds was recorded daily as and when it was occurred, and finally liveability of the birds was calculated from this by deduction. The experimental design followed for this experiment was a completely randomized block design. Statistical Analysis Statistical analyses were performed using Minitab software (Minitab version 16, 2010). All recorded data were subjected to analysis using one-way ANOVA with strain as a factor. The significance of difference between means was determined by the Fisher’s comparison test.

Achievement/Findings:

It can be concluded that Cobb-500 broiler strain has supported comparatively better growth responses in terms of body weight, feed efficiency, net profit and lower cost of production than those of Hubbard classic and MPK strains. So, Cobb-500 broiler strain may be recommended as economic and more suitable for rearing under the farming management in Bangladesh.
