This study was conducted aiming to evaluate the feasibility of NIRS and to establish a rapid assessment method to easily predict the quality of chicken meatball. Samples of meatball (n=123) were collected from Golden Harvest Company of Bangladesh. After collecting sample, spectra were obtained prior to analysis and a total of 369 NIRs were collected and stored in computer by DLP NIR scan Nano Software. To generate reference data 123 meatball samples were analyzed for proximate components, instrumental color CIE L*, a*, b*, and pH of meatball. After that a partial least square regression model for calibration and cross validation were developed for data analysis using The Unscrambler X software. Accuracies of the calibration models were evaluated using the root mean square error of calibration (RMSEC), root mean square error of cross-validation (RMSECV), coefficient of calibration (R²C) and coefficient of cross validation (R2 CV). Calibration equations were developed from reference data using partial least squares regressions. The standard deviation is 2.41, 0.14, 2.1, 0.41, 1.31, 0.31, 1.26, 0.38, and 0.38 for L*, a*, b*, pH, DM, moisture, CP, EE and ash respectively which indicates that all values are adequate for analytical purposes. Predictive ability of the models was assessed by coefficient of determination of cross-validation (R2 CV) and root mean square error of cross-validation. Predictions were good (R2 CV=0.84) for lightness (L*), (R2 CV=0.72) for redness (a*), (R2 CV=0.77) for yellowness (b*), (R2 CV=0.78) for pH, (R2 CV=0.73) for CP, (R2 CV=0.83) for EE (R2 CV=0.72) for moisture, (R2 CV=0.72) for DM and (R2 CV=0.74) for ash.

This experiment was conducted with five (5) treatments (T1 , T2 , T3 , T4 and T5 ) where T1 = 0 Permanent incisor, T2 = 2 Permanent incisors, T3 = 4 Permanent incisors, T4 = 6 Permanent incisors, T5 = 8 Permanent incisors having ten (10) replications. From this study, the mean rib eye muscle area (REA) and the mean rib fat thickness was 43.26, 49.93, 61.38, 70.43, 69.24 cm2 and 0.61, 0.68, 0.66, 1.07 and 0.97 cm with T1 , T2 , T3, T4 and T5 , respectively. The mean retail cut percentage of our indigenous beef cattle was 52.36, 52.27, 53.32, 52.69 and 52.58 with T1 , T2 , T3, T4 and T5 dental age groups, respectively. It also reveals that the overall maturity (on the basis of skeletal maturity and lean maturity) of indigenous beef cattle was A80 , B 90 , C 90, D80 and E 80 withT1 , T2 , T3, T4 and T5 dental age groups, respectively. Indigenous cattle population was fallen in the marbling sub groups of Slight91 , Small90, Small59, Modest57 and Moderate40 with T1 , T2 , T3, T4 and T5 dental age groups, respectively. With the combination of overall maturity and marbling score, indigenous cattle for beef production possess in the quality grade of Select, Choice, Commercial, Utility and Utility with respect to T1 , T2 , T3, T4 and T5 dental age groups. Indigenous cattle did not satisfy the criteria for the highest quality grade e.g., Prime to Standard and the lowest quality grade e.g. Cutter to Canner. In conclusion, dental age maturity had a highly significant (p<0.001) effect on average skeletal maturity, marbling score of the carcass and also had a significant (p<0.01) effect on rib fat thickness as well as on rib eye muscle area (REA) irrespective of all age group of indigenous beef carcass in Bangladesh.

In this study, we investigated whether this reduced water may also improve those parameters in broiler chickens exposed to 14 days-long chronic heat exposure. Broiler chickens (Gallus gallus) were fed either a control diet with tape water or control diet supplied with electrolyzed-reduced water for 14 d after hatch, and then exposed either to heat stress (34oC for 14 days), or kept at a thermoneutral temperature (24oC). Skeletal muscle substrate metabolism (3HADH and CS activities), adenine nucleotides concentration, enzymatic scavenging systems were studied. We confirmed that heat-stressed broilers decreased weight gain and feed consumption compared to control broilers. In contrast, heat-exposed broilers supplied with electrolyzed-reduced water significantly and definitely improved performance when compared to heat-stressed control broilers. On exposure to long-term heat treatments, broiler supplied with reduced water showed higher CS activity, indicating that the reduced water could improve energy-producing ability via modulating TCA cycle. We also found that the reduced water could definitely improve the total adenine nucleotide (TAN), adenylated energy charge (AEC), and ATP to ADP ratios under such conditions. On the other hand, broiler chickens supplied with reduced water kept relatively constant the SOD, catalase, and GPx activities, implying that reduced water could support the enzymatic scavenging systems. Taken together, these results suggest that broiler chickens supplied with electrolyzed-reduced water could improve energy producing ability via modulating TCA-cycle enzyme, and lead to improving performance.","PeriodicalId":18312,"journal":{"name":"Meat Research","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83985536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ether extract (EE) content decreased significantly (p<0.05) with different treatment levels and decreased with the increase of the days of intervals. Ash content increased significantly (p<0.05) with different treatment levels and increased with the increase of days of intervals. At different treatment levels and days of intervals, cooking loss decreased and pH value increased. Free fatty acid (FFA), peroxide value (POV) and 2-thiobarbituric acid (TBA) value were decreased significantly (p<.0.05) with different treatment levels but enhanced with the increase of days of intervals. Microbial assessments like total viable count (TVC), total coliform count (TCC) were decreased significantly (p<0.05) with different treatment levels but increased with days of intervals and, total yeast mould count (TYMC) were decreased with different treatment levels and days of intervals. Therefore, 4% sodium alginate can be recommended as a source of antioxidant in chicken sausage.","PeriodicalId":18312,"journal":{"name":"Meat Research","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86107097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
