Abstract/ Executive Summary:

A study was conducted to evaluate the body weight, weight gain and meat yield characteristics of different broilers produced by crossing 4 lines of chickens i.e. Male line white (MLW), Female line white (FLW), Male line colored (MLC), Female line colored (FLC). A total number of 193 crossbred chicks were produced by using the different crosses of MLW (?) × FLW (?), MLW (?) ×FLC (?), MLC (?) × FLW (?) and MLC (?) × FLC (?). Ad libitum feeds were given to the experimental birds from day-old to 42 days of age. Two chickens (one male and one female) from each cross were sacrificed to determine their meat yield characteristics. CB (Commercial Broiler) was used as control along with experimental crosses of chickens to evaluate the meat yield. The body weight at 1, 2, 3, 4, 5 and 6 weeks of age was significantly (P<0.001) different among different crosses of chickens. Significantly (P<0.05) higher body weight was found in MLW × FLW followed by MLW × FLC, MLC × FLW and MLC × FLC. The weight gain was obtained the similar trend as the body weight. Dressing yield of MLW × FLW was higher than that of other crosses of chickens. The findings of this study suggested that the MLW × FLW might be suitable for producing white feathered broiler, while the MLC × FLC as colored broiler.

End Date: 07-09-2012

Program Area: Variety and Species

Commodity: Chicken

Objectives:

To evaluate the growth performance and meat yield characteristics of white and colored broilers produced by developed sire and dam lines of chicken.

Methodology:

This study was conducted at the Bangladesh Agricultural University Poultry Farm, Mymensingh, for a period of six weeks from July 20 to September 7, 2012. A total of 193 straight run day old chicks from four line crosses (Male line white × Female line white, Male line white × Female line colored, Male line colored × Female line white, Male line colored × Female line colored) were used to evaluate their growth performance and meat yield characteristics. All chicks of whole line crosses were wing banded, weighed and randomly distributed in separate pens according to genotype. The chicks were brooded with electric brooder for 3 weeks. Ad libitum commercial broiler starter and grower feed from a reputed feed company named Nourish Poultry Feed Limited were provided to birds from day old to 21 days, 22 days to 42 days of age, respectively. Standard vaccination schedule were strictly followed for the prevention of economic diseases of broiler birds. Improved broiler farm management, housing facilities, rearing techniques and farm bio-security were ensured for the better production performance. Same lighting program were given to all birds during experimental period. At the end of the 6 weeks, one male and one female of nearly similar body weight from each genotype and one male and one female commercial broiler were fasted first. Feed was withdrawn 12 hours prior to slaughtering to facilitate proper bleeding. The initial weight before feed withdrawal and final weight before slaughtering was recorded. Then they were slaughtered, bled, scalded, de-feathered and eviscerated gradually. After slaughtering complete bleeding was facilitated and then the chicken were immersed in pre-warmed water (51– 55°C) for 120 seconds in order to loosen the feather of the carcasses. Then feathers along with the head, shanks, viscera, oil gland and lungs were removed. Thus, the dressed weight of the carcasses was recorded including giblets and dressing percentage was calculated. Data were recorded on weekly body weight, daily feed consumption and mortality. Two broilers (male and female) from each cross and two commercial broilers with similar body weight were slaughtered to compare their meat yield characteristics. The collected and computed data were analyzed using Linear Mixed Model implemented in JMP (Statistical Discovery Software, SAS Institute Inc., USA). Significant differences between genotypes were identified by Turkey’s HSD Test.

Achievement/Findings:

Body weight, weekly weight gain and meat yield characteristics were significantly higher in MLW × FLW rather than other three crosses. The performance of MLW × FLC was almost similar compared with MLC × FLC and MLC × FLW. The performance of colored male line considering parameters used in the study was significantly lower in both cases i.e. when it was mated with colored female or white female line. Finally, it might be suggested from the result of this study that white male line most suitable for superior performance than that of any kind of female line either white or colored.
