This research evaluated the effects of subzero saline chilling (SSC) with or without hot water spray (HWS) on broiler carcasses to improve chilling efficiency, carcass quality, and sensory attributes. Eviscerated broiler carcasses were subjected to one of the six chilling methods with or without HWS for 1 min as follows: 1) Water immersion chilling at 0.5 °C (WIC), 2) WIC after HWS at 68 °C for 1 min (WIC-HWS 68), 3) WIC after HWS at 71 °C for 1 min (WIC-HWS 71), 4) Subzero saline chilling at 4% NaCl/-2.41 °C (SSC), 5) SSC after HWS at 68 °C for 1 min (SSC-HWS 68), 6) SSC after HWS at 71 °C for 1 min (WIC-HWS 71). The SSC showed shorter chilling time than other treatments. The fillets from the SSC and SSC-HWS were more tenderized than the WIC and WIC-HWS, regardless of the HWS exposure. HWS treatments showed higher lightness values (or partially cooked appearance) than WIC and SSC. Significantly lower redness (a*) values were observed in the SSC68 and SSC71 than in the remaining treatments, except the WIC68. In the consumer panel, the carcass fillets from SSC-HWS showed higher hedonic scores than WIC and WIC-HWS for flavor, juiciness, tenderness, saltness, and overall acceptance, with an intermediate score observed for SSC in tenderness and juiciness. In descriptive sensory analysis, the fillets from SSC, WIC and SSC-HWS were rated less intense for bloody and cardboardy attributes than WIC-HWS. Based on those results, the combination of SSC-HWS improved meat tenderness and sensory attributes over the control, while the SSC improved chilling efficiency among all treatments.</div></div>","PeriodicalId":15240,"journal":{"name":"Journal of Applied Poultry Research","volume":"34 2","pages":"Article 100516"},"PeriodicalIF":1.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CD was fed <em>ad libitum</em> to the control group<em>,</em> and the other four groups were fed the TD employing quantitative restriction so as to provide 4 different intakes of ME (194, 204, 214, and 224 kcal/b/d) in Experiment 1 for a duration of 5 weeks from 71 to 76 weeks of age. Similarly, in Experiment 2, TD was fed in restricted quantities so as to restrict the ME intake to 158, 162, 175, and 184 kcal/b/d from 81 to 85 weeks of age, while the control group received <em>ad libitum</em> feed intake (FI). After the energy restriction phase, all the groups were offered CD <em>ad libitum</em> (77-80 and 86-91 weeks of age, respectively, in experiments 1 and 2).

Based on the results, it can be concluded that in WL laying hens (81-91 weeks of age), the energy restriction to 158 kcal/b/d for five weeks can be adopted as a less stressful method for cessation of EP to nearly zero percent, and resumption of <em>ad libitum</em> feeding of the CD will increase EP and reduce serum oxidative parameters within four weeks as compared to the pre-restriction phase without affecting egg quality and humoral immunity.</div></div>","PeriodicalId":15240,"journal":{"name":"Journal of Applied Poultry Research","volume":"34 2","pages":"Article 100517"},"PeriodicalIF":1.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hundred forty hatching eggs of the same weight (64±1 gram) were used. The eggs hatched in both locations simultaneously. The studied parameters were incidence of ascites syndrome at 14, 21, and 42 days, lung and heart volume at 14 and 42 days, carcass performance, antioxidant status, hematological measurements, thyroid hormone levels, nitric oxide, lipid profile, uric acid, and liver enzyme level. Results showed that the strain on SOD, T3, and cholesterol, hatching altitude on lung and heart volume at 42 days, and T3, and the interaction of strain at hatching altitude on lung and heart volume at 42 days, spleen percentage, nitric oxide level, and RV-to-TV ratio were significant effect (<em>p</em> &lt; 0.05). The incidence of ascites and heart volume increases with age, but lung volume decreases. Even though there is no significant difference between the two strains and the hatching altitude in most of the traits, the comparison of the numerical values of the parameters indicates that the high-altitude hatching and the Cobb strain have higher values.

Due to the lack of information in the literature, this study quantified daily WC trends for broilers grown to nine weeks under commercial conditions. Daily WC was monitored between d 8 to 63 and varied between two flocks. Mean cumulative WC was 14,629 L/1,000 birds, ranging from 13,982 (Flock 2) to 15,276 L/1,000 birds (Flock 1). At wk 8, flocks from this study consumed between 27 to 46% more water on a L/1,000 birds/wk basis than data reported 20 to 30 yrs ago. However, broilers in this study consumed less water to achieve equivalent body weights (BW) when compared to past studies. While reporting broiler WC in units of L/1,000 birds makes discussions in the field easier when trying to estimate the expected water needs of a farm, broiler genetics and husbandry practices continue to increase bird weights earlier in the flock. Including a WC:BW in terms of mL of WC to kg of BW can provide a more accurate comparison. Future WC research studies should include additional data to allow for better comparisons between studies: weekly BW, environmental set-points, in-house air temperature, lighting photoperiod and intensity, diet composition by feeding phase, drinking system, and water line pressures, and others.</div></div>","PeriodicalId":15240,"journal":{"name":"Journal of Applied Poultry Research","volume":"34 2","pages":"Article 100511"},"PeriodicalIF":1.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although our breast meat models proved to be good, the thigh and drum models did not demonstrate a high correlation between observed and predicted weights probably due to the orientation of the image and any potential shifts made during image capture.
