“…The high concentrations of NSP in plant sources such as wheat and other grains affect the digestive process (viscosity) and litter quality [24]. Nevertheless, feeding measures and housing conditions are as important as managing the quality of litter, especially its moisture content (the key factor) with regards to reducing the incidence and severity of FPD [25]. Therefore, against this background, the objectives of this experiment were to test whether rye could replace corn or wheat and to estimate the effect of upper inclusion levels of crushed corn or squashed rye of up to 30% in broilers on growth performance, litter quality, foot pad health, digesta viscosity, organ traits and intestinal morphology.…”

Rye could offer diverse benefits in terms of sustainability if it could replace parts of the main cereals, corn and wheat, in broiler diets. A total of 256 broilers, Ross 308, were randomly allocated into 32 pens. From day 14 till day 42, the birds were divided into four feeding groups (eight replicates each). The control group received a conventional finisher diet “control”, whereas in the other groups, a pelleted supplementary feed was offered (SFI to corn and SFII to rye), to which crushed corn (SFI-Corn) or squashed rye (SFII-Rye) was added. The fourth group received a mixture of 50% SFI-Corn and 50% SFII-Rye. The cereal level was increased weekly (5%, 10%, 20%, 30%) at the expense of the supplementary feeds. No significant effects were observed for body weight at d 42 and excreta viscosity between all groups. Overall, foot pad health was excellent. Compared to the control group, birds fed SFI-Corn displayed a significant increase in gizzard relative weight, whereas, in contrast to all other groups, ileal villus height was significantly lower. In conclusion, feeding SFI-Corn or SFII-Rye diets had no negative influences on performance, litter quality and digesta viscosity, whereas SFI-Corn partially affected ileal morphology.

“…This could be related to the accessibility of more seating positions offered by the environmental enrichment or maybe by the increased activity, which could also lead to improved leg health [16]. A main influence of wet litter on the development of FPD is described in the literature [52], although there are a lot of other factors influencing this as well [53]. The results obtained in the current study reveal that the environmental enrichment had no negative influence on the litter quality.…”

The aim of this study is to evaluate the influence of environmental enrichment on the growth performance, litter and/or air quality as well as animal welfare indicators of broilers. Control groups (CG) and trial groups (TG) were housed under identical conditions during six fattening runs, with the TG having three types of environmental enrichment and a Farmer-Assistant System (FAS). A representative number of 50 birds were weighed and litter samples were taken at d 14, 21 and 28. Additionally, the same broilers were examined for foot pad dermatitis (FPD) on those days. The average bodyweight of the birds in the CG was significantly lower (1671 g) only at d 28 compared to TG (1704 g); at d 14, d 21 and d 33 at the slaughterhouse, no significant differences were observed. The dry matter content in the litter did not significantly differ between CG and TG. Birds housed in CG had significantly higher FPD scores at d 14 (1.24) and d 21 (2.19) compared to those housed in TG (0.73 and 1.52, respectively). No effects on air quality parameters, such as CO2 and NH3, were seen between the groups. Overall, our study shows no negative influences of environmental enrichment on growth performance, litter and air quality.

“…Supplementation of the broiler diet with a highly digestible marine calcium source, at lower dietary concentration (0.6%) may prevent reduced skeletal integrity [82]. Poultry nutrition and the litter quality are the main factors that are responsible for the development of foot pad dermatitis (PFD), which is characterized by ulcerated lesions on the pad of the foot [9,96]. Abd El-Wahab et al (2018) examined the effect of different protein sources (soybean, rapeseed, hemoglobin and algae meal) on the FPD score in broilers (160 one day old).…”

“…The high FPD score can result from the chemical composition of diet (the high content of sodium-about 2 g/kg of dry mass and potassium-about 9 g/kg of dry mass) which caused excessive consumption of water. It affected the deterioration of the litter quality [96].…”

Poultry production is an important area of the agricultural economy. Nowadays, there is an interest in novel sources of feed additives that will improve production performance and poultry health. As an easily available and renewable biomass rich in biologically active compounds, seaweeds can meet this demand. Different forms of seaweeds–seaweed powder from naturally occurring biomass, cultivated or waste biomass, extracted compounds, post-extraction residues or liquid extracts–may be used in poultry feeding. Inclusion of this unconventional material in the poultry nutrition can positively influence the poultry performance along with its health and enrich poultry products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids and pigments. Seaweeds also reduce lipids and cholesterol in eggs. Moreover, due to their unique properties, they can serve as an alternative to antibiotic growth promoters. This review presents the latest developments in the use of seaweeds in poultry nutrition, as well as its limitations.
