A 2 x 3 factorial arrangement with 2 types of fat including neutralized sunflower soapstock (NSS) and soybean oil (SO) at 3 levels of fat inclusion (2, 4, and 6%) was used with 5 replicates per treatment using 750 one-day-old broiler chicks in a completely randomized design. At the end of the study (d 36), 10 broilers from each replication were processed at a commercial slaughtering facility. Six carcasses from each replicate were used for meat quality evaluation. With the exception of 3 responses [breast meat lightness (L*) at 1 and 2 d, and redness (a*) at 5 d], there were no interactions between fat source and level. Breast meat pH at 15 min was not significantly affected by the dietary treatments. However, breast meat pH at 24 h postmortem was decreased (P < 0.01) in broilers fed the NSS. Breast meat cooking loss, shear force, and color did not differ between fat sources. Breast meat cooking loss decreased (P < 0.05) when the dietary levels of fat increased. Thigh meat TBA reactive substances were not different due to dietary fat source and level. Breast meat and skin L* value significantly decreased when the dietary levels of fat increased. Breast meat a* value was highest for the 6% fat fed birds on d 2 (P < 0.05) and d 5 (P < 0.01). Higher dietary fat levels decreased the b* values of breast meat except d 5. Breast skin yellowness (b*) value was higher (P < 0.01) for the SO-fed birds compared with NSS-fed birds. Thigh meat of the birds fed the NSS was lighter (P < 0.05) than that of the birds fed SO diets except d 5. Overall, data suggest that NSS can be used as an alternative fat source to SO with little effect on meat quality.eninfo:eu-repo/semantics/openAccessBroilerNeutralized Sunflower SoapstockSoybean OilMeat QualityArticle10.3382/ps.2012-0227291923612369229124742-s2.0-84865484635Q1WOS:000307680300035Q1
