Publikováno v: Animals, Vol 9, Iss 2, p 53 (2019)

The recent increases in stocking density, in extreme cases resulting in ‘crowding’, have a major impact on poultry welfare. In contrast to available research on adult laying hens, there is a gap in the literature studying the rearing phase. The p

Litter and perch type matter already from the start: exploring preferences and perch balance in laying hen chicks

Autor: Lena Skånberg, Cecilie Bramgaard Kjærsgaard Nielsen,, Linda J. Keeling

Publikováno v: Poultry Science, Vol 100, Iss 2, Pp 431-440 (2021)

Early chick environment, such as provision of litter and perches, can be a predictor of laying hen welfare. Inadequate or nonpreferred litter and perch types could have similar negative effects as those seen when not providing these resources at an e

This study investigated the effects of fermented-feed diets on growth performance, immune status, and antioxidant responses in laying hen chicks and the underlying molecular mechanism, specifically, the role of the nuclear factor-κB (NF-κB) signali
