Energy and nutrient intake on white striping, wooden breast and carcass composition in broilers from three genetic lineages at different ages

Application of bioelectrical impedance analysis to assess body composition of male and female broiler chickens from 2 different strains throughout the growth period

“…In the study by Panisson et al (2022) , differences in BC among male broilers of 3 distinct genetic lineages (Embrapa021, Ross308, and Cobb 500) were reported at 28, 35, 42, and 49 d of age under 3 different nutrient densities. The author observed higher fat content at every age studied and increased protein content at 49 d of age in Cobb 500 compare to Ross 308.…”

“…Recent studies have significantly contributed to enhance the understanding of BC, such as the work conducted by Vargas et al (2020) and Panisson et al (2022) .…”

Broiler White Striping: A Review of Its Etiology, Effects on Production, and Mitigation Efforts

“…They characterized the heritability of traits such body weight and body yield at h 2 = 0.271 -0.418 with WS at h 2 = 0.338. In Brazil, Panisson et al [51] compared three lines-high yield Cobb 500 ® and Ross 308 ® with moderate yield Embrapa 021 ® -with diets of varying nutrient densities and found that, regardless of diet, the higher yield lines had a greater incidence of WS, with the higher yield lines being 24.4-28.0 and 11.0-25.1 times, respectively, more likely to have higher WS scores by days 42 and 49. When describing the history of broiler production, comparisons were made between broilers from the 1950s and 1960s to today's broilers.…”
