Broilers Welfare and Economics under Two Management Alternatives on Commercial Scale

The Effects of Different Breeding Methods on Fattening Performance and Parameters Related to Slaughter, Carcass and Some Meat Quality in Broiler Chickens

“…The review of previous literature reports has revealed that a consensus has not been reached on this issue, and that to date; very different results have been obtained. In agreement with the findings of the present study, Hypes et al 16 (CBG 1.832 -FBG 1.911 g), Türkyılmaz et al 17 (CBG 2168.4 -FBG 2261.1 g) and Fouad et al 7 (CBG 1616.27 -FBG 1862.52 g) reported that the final body weight of broiler chickens was higher in Group FBG compared to Group CBG and that this difference was statistically significant. On the other hand, Elibol 18 (CBG 1792 -FBG 1745 g), Reece et al 19 and Andrews et al 20 indicated that the final body weights of Group CBG were higher than those of Group FBG and that the two groups differed from each other significantly.…”

“…In parallel with the findings of Fouad et al 7 , Athar et al 23 reported the feed consumption values of Groups CBG and FBG as 4.46 kg and 4.43 kg, respectively, and noted that the difference between the two groups was statistically insignificant. In a study conducted by Zahoa et al 24 , in which the effect of three different types of cage floor (wire, plastic and bamboo) on the growth performance of broiler chickens was investigated, the differences between the feed consumption values of the trial groups was found to be statistically insignificant, and these values were reported as 3.41 kg, 3.28 kg and 3.21 kg for the groups raised in cages with wire, plastic and bamboo floors, respectively.…”

“…Contradictory to the findings of the present study, Fouad et al 7 reported the total feed consumption values of broiler chickens included in Groups FBG and CBG as 3096.48 g and 3139.46 g, respectively, and indicated the absence of any statistical difference between the trial groups. In parallel with the findings of Fouad et al 7 , Athar et al 23 reported the feed consumption values of Groups CBG and FBG as 4.46 kg and 4.43 kg, respectively, and noted that the difference between the two groups was statistically insignificant.…”

“…Furthermore, Swain et al 4 suggested that neither cage-based nor floor-based growth systems had any effect on body weight gain, feed consumption or carcass traits in broiler production. While some researchers have claimed that cage-based growth systems enable better growth performance and a higher survival rate, and thus, provide economic advantage when compared to floor-based growth systems 5,6 , some other researchers have reported that floor-based growth systems are more economical 7 . Duncan 8 has highlighted the inadequacy of physical space and behavioral restrictions as the major disadvantages of cage-based growth systems.…”

Linhagens de frangos caipiras criadas em sistema semi-intensivo em região de clima quente

“…O sistema de semiconfinamento permite que as aves tenham livre acesso às áreas de pastejo, para que estas expressem seus comportamentos naturais, resultando em diferenças particulares na qualidade da carne, quando comparadas com as aves criadas confinadas (Fanatico et al, 2007;Mikulski et al, 2011). Por outro lado, as condições ambientais podem interferir no bem-estar, saúde e comportamento das aves, podendo se refletir em suas características fisiológicas e produtivas (Fouad et al, 2008;Tan et al, 2010).…”
