Item type:Publication, Meat characteristics from four different cutting parts of Cherry Valley duck(2018-08-14); The objective of this study was to investigate the duck meat characteristics in 4 main parts: breast, fillet, leg, and thigh. A total of 30 Cherry Valley ducks were used in this study. They were slaughtered at the age of 42 days. Carcasses were cut and collected the boneless and skinless of breast, fillet, leg, and thigh for measuring meat characteristics. The results showed that fillet and leg had the longest sarcomere length at 6, 12, and 24 hour post mortem (P<0.05). The highest pH was from leg and the lowest pH was from breast and fillet (P<0.01). The cooking loss percentage of breast was the highest while the lowest was from leg (P<0.01). Thigh and leg were tougher than breast and fillet. Shear force value negatively correlated with sarcomere length at 24 hour post mortem and with pH but positively correlated with L∗ value. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effect of hempseed products on growth performance, carcass yield, omega-3, and omega-6 fatty acids in broiler: A meta-analysis(2024-01-01); Hempseed is the edible fruit of the Cannabis sativa L. plant, potentially serving as feed ingredients in broiler production due to its high nutritional value. Therefore, this meta-analysis aimed to determine the effect of hempseed products (seeds, cakes, or oils) on body weight (BW), feed intake (FI), feed conversion ratio (FCR), carcass yield (CY), and fatty acid (FA) composition (ω-3 and ω-6) in broiler chicken. Ten eligible publications were retrieved from Google Scholar and Scopus databases for the meta-analysis. The random-effects model was used for data analysis in OpenMEE software. Results were expressed as standardized mean differences (SMD) at 95% confidence intervals (CI). Results show that dietary hempseed products increased ω-3 FA (SMD = 1.107; P<0.05) and ω-6 FA (SMD = 0.987; P<0.01) but reduced BW (SMD = -0.403; P<0.05) and FI (SMD = -0.470; P<0.05) compared to the controls. On the other hand, CY (SMD = 0.053; P>0.05) and FCR (SMD = 0.046; P>0.05) were not significantly influenced by hempseed product supplementation. Subgroup analysis revealed that hempseed oil reduced BW (SMD = -1.041; P<0.05) and FCR (SMD = -0.797; P<0.05) but enhanced both ω-3 FA (SMD = 2.372; P<0.01) and ω-6 FA composition (SMD = 1.630; P<0.01). There were no adverse effects of hempseed and hempseed cake on BW (P>0.05), but a higher FCR (SMD = 0.658; P<0.05) was obtained on broilers fed with hempseed. Moreover, dietary hempseed and hempseed cake also increased ω-3 FA (SMD = 0.952; P<0.05) and ω-6 FA composition (SMD = 1.107; P<0.01), respectively. This study concluded that dietary hempseed products had beneficial effects on the fatty acid composition of meat. However, its effect on growth performance should be considered. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effect of ractopamine on physicochemical characteristics and collagen solubility in finishing pigs(2018-08-14); ; Chaweewan, KamonThe objective of this study was to investigate physicochemical characteristics and collagen solubility of pigs fed with dietary ractopamine (RAC) during finishing period. Thirty of three-way crossbred pigs (Large White × Landrace × Duroc) with an initial bodyweight (BW) of 18.0 ± 0.5 kg were randomly assigned to one to three dietary RAC inclusions (0, 20, or 40 mg/kg) fed during finishing period (60-100 kg BW). Each group consisted of five gilts and five barrows. After 109 day of raising period, all pigs were slaughtered at the average weight of 100 kg. Longissimus dorsi muscle (LD) was taken from each carcass after overnight chill and analyzed for physical characteristics, chemical composition, and collagen solubility. The LD from pigs fed 40 mg/kg of RAC had lower a∗ value (p < 0.01) than others. Pigs fed with 40 mg/kg of RAC had higher Warner-Bratzler shear force (p < 0.05) than pigs fed without RAC. Pigs fed with dietary RAC had lower glycogen content than control (p < 0.01). While other chemical compositions and collagen solubility of LD were not affected by dietary RAC (p > 0.05). Gilts had larger muscle fibers (p < 0.01), lower glycogen content (p < 0.05), higher content of insoluble collagen (p < 0.05), total collagen (p = 0.054), and collagen solubility (p = 0.054) than barrows.
