Abstract/ Executive Summary:

Six males and 6 females in each genetic group (G) of broiler (Br), indigenous naked neck (Nana) and full feathered chicken (nana) at set three weight groups (WG); 0.75 kg, 1.00 kg and 1.25 kg were collected from different local markets and slaughtered. Meat yield traits of slaughtered chickens were recorded to identify a suitable G at a specific weight by comparing the meat yield of 3 Gs. Broiler had the highest breast, breast: dark meat and heart weight followed by Nana and nana while Nana had the highest gizzard weight followed by nana and Br. Dark, thigh, and giblet weight tended to increase in Nana followed by nana and Br. Male performed better than female for yielding meat except breast: dark meat and abdominal fat which was higher in female than that in male. The highest breast: dark meat of broiler, Nana and nana was observed in 1.00 kg, 0.75 kg and 1.25 kg WG, respectively. Indigenous chickens showed decreased head and feather weight but increased skin weight with increasing live weight. Notwithstanding, the highest skin weight was observed in Br followed by nana and Nana. The remarkable interaction of G x sex (S), G x WG, and G x S x WG was observed for breast: dark. The above findings reveal that Nana is comparable to Br, and better than nana for yielding meat. Of the feathering types, broiler is superior to nana for yield of meat. However, more studies are needed to confirm these findings.

Program Area: Variety and Species

Commodity: Chicken

Objectives:

To identify a suitable genetic group of chicken for meat production by comparing meat yield of broiler, indigenous heterozygous naked neck and full feathered chicken at a specific weight.

Methodology:

The experiment was carried out at Bangabandhu Sheikh Mujibur Rahman Agricultural University, (BSMRAU), Gazipur-1706, Bangladesh during the period of May to December 2009. A total of 36 (3 x 6 x 2) chickens from 3 genetic groups (G) equal number in sex under each G viz.; 12 Arbor Acre commercial broiler hybrids (Br), 12 indigenous heterozygous naked neck (Nana), 12 indigenous full feathered (nana) chickens at 3 weight groups (WG); 0.75 kg, 1.00 kg and 1.25 kg were collected from different local markets of Gazipur district. As per consumer demand, only marketable weight of chickens was considered in this study but not age of the birds. Available heterozygous naked neck genotype (Nana) was chosen based on a tuft of feather on the ventral side of the neck region. The collected birds were fasted for 12 h, and then sacrificed, weighed, eviscerated, dressed, dissected, and the meat stripped from carcass. The recorded data of each bird were live weight, weight of feather, head, heart, gizzard, neck, breast meat, thigh meat, drumstick meat, skin, abdominal fat, wing meat, trimmed meat, dark meat (thigh meat + drumstick meat+ wing meat + trimmed meat), total meat (breast meat + dark meat), and weight of thigh bone, drumstick bone, wing bone, and neck weight. Meat yield traits were converted into percentage of individual live weight prior to analyzing the data statistically. The recorded data for a 3 (genetic group; G) x 2 (sex; S) x 3 (weight group; WG) factorial experiment in Completely Randomized Design were analyzed using Genstat computer package program. Analysis of variance was performed for partitioning the variances to G, S, WG, G x S, G x WG, S x WG, G x S x WG and error to compare meat yield among treatment combinations. Standard error differences (SED) were calculated to isolate the significant difference among the mean values.

Achievement/Findings:

The present findings reveal that broiler yielded breast meat, breast: dark meat ratio, and heart weight that better than in Nana, and nana. However, the highest gizzard weight and a tendency for increasing dark, and thigh weight were found in Nana followed by nana, and Br. The other meat yield traits were almost similar among the genetic groups. Therefore, Nana was comparable to broiler, and better than nana for meat yield traits. Of the two feathering types, broiler performed better than nana for meat yield traits. Male was found to be the superior to female for meat yield traits except abdominal fat and breast: dark meat ratio which was higher in female. The suitable WG of broiler, Nana and nana was 1.00 kg, 0.75 kg and 1.25 kg, respectively for meat yield traits. Therefore, this study suggests doing comprehensive research on meat yield traits of 3 genetic groups.
