Meat quality characteristics of fast-growing broilers reared under different types of pasture management: Implications for organic and alternative production systems (Part II)

SUMMARY Currently, there is little scientific information regarding the effect of differing housing types and production methods on the final quality of broiler meat. The purpose of this study was to evaluate meat quality characteristics of commercial fast-growing broiler chickens when raised in portable vs. fixed housing, with or without access to pasture. Fast-growing broilers are being grown by many small farm poultry producers due to their favorable attributes, including greater breast meat yields, a more uniform carcass, and higher feed efficiency than heritage or slower growing breeds. The pasture land used in this study closely matched the lands common to this local area. It was a pasture composed of a mix of tall fescue, Bermuda grass, and a lesser amount of legumes and forbs. The experiment had 4 treatment groups: (1) small, portable hoop houses with access to pasture, (2) small, portable hoop houses without access to pasture, (3) a fixed house with access to the outdoors, and (4) a fixed house without access to the outdoors. The study was conducted during spring and fall within the same yr to evaluate if any seasonal effects on carcass or meat quality were present. Overall, the access to pasture did not alter meat quality parameters such as moisture, protein, fat percentage, pH, color, texture, cooking loss, or shear energy when compared to birds without pasture access. Since forages contribute to the nutritive value of the meat and may help in reducing costs, the type and quality of forage choices in pastures are important considerations for these production methods and need to be explored further for pasture production systems.
