Slaughter age and carcass traits of pheasants

WOS: 000082977900007This study was conducted to determine growth performance and carcass traits of pheasants at different slaughter ages. Day-old male and female chicks of a native pheasant genotype were used in the trial. The pheasants were grown in a floor rearing system. Birds were slaughtered at 13, 14 and 15 weeks of age. The differences between the live weights of male and female pheasants were found to be significant (P < 0.05) at all slaughter ages. The average live weights of male and female birds combined were 868.69 +/- 26.78, 927.19 +/- 34.59 and 982.87 +/- 42.59 g for the 13th, 14th and 15th week of age, respectively. Feed efficiency was recorded as 4.60, 4.88 and 5.14 for the same slaughtering ages. The slaughter yield and the percentages of breast, thighs and edible internal organs were determined at the 13th, 14th and 15th week of age as 74.19%, 73.13% and 74.30%; 35.90%, 35.85% and 35.55%; 30.12%, 30.97 and 29.13%; 5.93%, 5.83% and 6.03%, respectively

Hyperglycemia as a risk factor for postoperative early wound infection after bicondylar tibial plateau fractures: Determining a predictive model based on four methods

Objectives: Identify a glucose threshold that would put patients with isolated bicondylar tibial plateau fractures at risk of early wound infection (i.e. less than 90 days). Design: Retrospective review of medical records. Setting: Academic American College of Surgeons (ACS) Level 1 trauma center. Patients: Adult patients between 2010 and 2015 with an operatively treated isolated bicondylar tibial plateau fracture and at least three glucose measurements during their hospitalization. Main Outcome Measurement: To predict infection using four different methods: maximum preoperative blood glucose (PBG), maximum blood glucose (MGB), Hyperglycemic Index (HGI), and Time-Weighted Average Glucose (TWAG). Results: 126/381 patients met our inclusion criteria. Fifteen (12%) patients had an open fracture and 30/126 (23%) developed an infection. Median glucose for each predictive method studied was 114 (IQR 101.2–137.8) mg/dL for PBG, 144 (IQR 119–169.8) mg/dL for MBG, 0.8 (IQR 0.20–1.60) mmol/L for HGI, and 120.4 (IQR 106.0–135.6) mg/dL for TWAG. As expected, infected patients had higher PBG, MGB, and TWAG. HGI was similar in both groups. None of these differences prove to be statistically significant (p > .05). Logistic regression models for all the methods showed that having an open fracture was the strongest predictor of infection. Conclusion: It is well known that stress-induced hyperglycemia increases the risk of infection, we present and compare four models that have been used in other medical fields. In our study, none of the methods presented identified a glucose threshold that would increase the risk of infection in patients with bicondylar tibial plateau fractures.
