Conceptual
Pasta meat (SM), woody nipple (WB), and light striping (WS) is actually myopathies which affect brand new pectoral muscles out-of fast-expanding broiler chickens. Thus, the goal of this research would be to assess the prevalence and you will risk factors associated with these myopathies in the a real estate agent people out-of Canadian broilers. Out of , 250 haphazard nipple fillets off each of 37 flocks (overall, 9,250) was taken from a few running flowers and examined to the exposure and you can seriousness away from myopathies. Market analysis (age.grams., intercourse and you may mediocre live weight), ecological criteria into the build-aside several months (age.grams., temperature), and husbandry details (e.grams., vaccination) had been accumulated for each and every head. Connections anywhere between these types of things plus the myopathies was basically checked playing with logistic regression analyses. The newest incidence away from SM, severe WB, and you can lighter or average WS is 36.3% (95% CI: 35.3–37.3), eleven.8% (95% CI: 11.2–12.5), and 96.0% (95% CI: 95.6–96.4), respectively. Really (85.1%) of one’s fillets displayed multiple myopathies. Regression analyses revealed that chances away from SM increased which have live weight (Or = 1.30, 95% CI step 1.01–1.69) and better ecological heat within the expand-out months (Otherwise = 1.75, 95% CI 1.31–dos.34).
