The relationship between the severity of footpad dermatitis (FPD) and growth performance parameters (live weight, condemnation rate, leg meat yield and breast meat yield) was investigated in a total of 63 million broiler chickens that were processed over a period of 1,053 days between 2008 and 2012 at a full-scale processing plant in Kagoshima Prefecture, Japan. FPD scores and carcass data were...

Extracts of essential oils (EO) such as thymol, carvacrol, and cinnamaldehyde that occur naturally in oregano, thyme, and cinnamon have previously been shown to have positive effects on broiler performance. However, it was not known if these EO compounds affect the sensory characteristics of the broiler meat produced. The present study examined the effects of feeding 3 different blends of EO (D...

An experiment was performed to evaluate the effects of dietary metabolizable energy (ME) and lysine on carcass characteristics and meat quality in Arbor Acres (AA) broilers from 1 to 56 days of age. A total of 2,970 1-d-old male broiler chicks were randomly allocated to nine dietary treatments (three ME levels in combination with three lysine levels), and dietary ME and lysine concentrations we...

This investigation was carried out to determine the effects of different levels of digestible threonine on growth performance, dressing percentage and breast meat yield of broiler chicks. One hundred and twenty day old chicks were randomly divided into four groups A, B, C and D which were fed on four diets having (CP 21% and ME 2950 Kcal/kg) with four different levels of digestible threonine 0....

This experiment was conducted to compare carcass characteristics of native quality chicken white Lueyang (WL), modern commercial broiler strain Arbor Acres breeder (AA) and their respective F cross when 1 achieve a common live body weight. A total of 300 day-old chicks were allotted to three groups and reared under the same conditions until they reached market weight (1800±20 g) respectively, t...

The effects of various postchill deboning times on functional, color, yield, and sensory attributes of broiler breast meat were determined. Broiler breast muscles were deboned at 2, 4, 6, and 24 h postmortem, and pH, color change, cooking yield, shear force values, and sensory traits of the breast meat were recorded. Data were examined by multivariate data analysis, namely principal component a...

One of the consequences of intense genetic selection for growth of poultry is the recent appearance of abnormalities in chicken breast muscles, such as white striping (characterised by superficial white striations) and wooden breast (characterised by pale and bulged areas with substantial hardness). The aim of this study was to evaluate the quality traits of chicken fillets affected by white st...

Chilling is a critical step in poultry processing to attain high-quality meat and to meet the USDA-Food Safety and Inspection Service temperature standards. This study was conducted to determine the effects of commercially available chilling systems on quality and safety of broiler meat. A total of 300 carcasses in 2 replications were randomly selected from a commercial processor and subjected ...

Meat quality (pH, colour, drip and cooking loss, Warner-Bratzler shear force) and muscle characteristics (lipid and glycogen contents) were compared among two experimental divergent lines of broilers, selected for high abdominal fatness (HF) or low abdominal fatness (LF). By comparison to the LF line, the HF line exhibited a 2.8 fold higher abdominal fat percentage. It also exhibited a slightly...
