The Welfare Status of Hens in Different Housing Systems – A Review

Abstract: The currently used poultry farming methods, which aim to maximise economic profit, are based on ever new technological solutions that improve flock management and increase bird performance. However, they do not always meet the natural needs of birds. Every housing method and technological solution currently in use is faced with some issues, such as social stress, adverse temperature/humidity conditions, risk of zoonoses, and behavioural pathologies, which determine poultry performance and welfare. Disregard fo… Show more

“…Body condition score in laying hens of DLS group was better than that of the CON group. Birds with poor feathers not only present a problem for welfare, but also affect egg production (Tactacan et al, 2009;Sosnówka-Czajka et al, 2010;Sözcü et al, 2022). Bad 9.36 ± 0.65 a 0.031 CON -conventional feeding system, DLS -digital livestock system; data are presented as mean value ± SEM (standard error of the mean), n = 15; ab -means within a row with different superscripts are significantly different at P < 0.05 environment and feeding management conditions of laying hens of CON group might have increased feather loss compared to the DLS group, thus impairing animal welfare (Blatchford et al, 2016;Widowski et al, 2017).…”

The high score of feather loss in laying hens of CON group might have contributed to wing feather deterioration (Lay et al, 2011;Sosnówka-Czajka et al, 2010). In this study, appearance, feather condition, body condition such as the comb, beak, keel bone damage, and plumage, and health score of laying hens of the DLS group were improved compared to the CON group.…”

“…Contaminated eggs have been a problem in free-range systems. The main factors affecting these results are nest contamination or egg laying on litter [42], [43]. The study [37] reported that the proportion of dirty eggs higher in the free-range system compared to the cage system, especially in the hens' last phase of the production period, could be related to unfavorable rainy weather conditions.…”
