Special Issue Information

Dear Colleagues,

The search for alternative and novel feeds for poultry addresses the urgent need to enhance nutritive value and improve product quality and/or environmental aspects, aligning with the Sustainable Development Goals (SDGs) by promoting sustainable food systems, responsible resource use, and climate action.

Alternative and novel feeds such as agro-industrial by-products, co-products, plants, insect meal, algae, and fermented and enzymatically treated ingredients, among other novel sources, offer promising avenues to enhance the sustainability of the poultry industry. These alternative feed ingredients can improve nutrient efficiency, reduce the reliance on conventional ingredients, and minimize environmental challenges. Simultaneously, they have the potential to enhance the quality of animal-derived products, such as meat and eggs, by influencing factors like fatty acid profiles, protein composition, bioactive compounds, antioxidant profile, shelf-life, and overall sensory appeal.

This Special Issue aims to bring together contributions from multidisciplinary perspectives focusing on the nutritive value of such feeds, their impact on animal health and welfare, their effects on product quality, and their role in mitigating environmental concerns.

All types of papers related to the topic will be considered.

Pequi oil (PO) is a natural feed additive rich in bioactive compounds, which can modulate antioxidant and immunological systems. Thus, the aim of this study was to evaluate the proteomic profile of laying hens supplemented with PO under heat stress conditions. Ninety-six 26-week-old Lohmann White hens were housed in a completely randomized design with a 2 × 2 factorial arrangement, with two climate chambers (cyclic heat stress and thermoneutral) and two diets (control and 0.6% PO). At 38 weeks old, liver samples were collected for protein extraction and digestion, and were submitted to liquid chromatography–tandem mass spectrometry (LC-MS/MS). A total of 996 differentially expressed proteins were identified in the liver proteome of laying hens fed with 0.6% PO under heat stress. These upregulated proteins (0.95 ≤ p ≤ 1.00) are associated with lipid metabolism (apolipoprotein B; vitellogenin-1; ovotransferrin), the antioxidant system (protein disulfide-isomerase A4; superoxide dismutase 1_ soluble; catalase), the immune system (Ig-like domain-containing protein) and chaperones (HSP 90; HSP 70). PO positively modulates a network of heat shock proteins and antioxidant enzymes, and the unique proteins identified can contribute to the discovery of new biomarkers related to heat stress reduction by phytogenic additives.

Passion fruit seed oil (PFSO) is rich in bioactive compounds, which can enhance laying hens’ health and performance. The current study was conducted to investigate the effect of increasing PFSO supplementation in laying hens’ productive performance, egg quality, relative weight and length of organs, plasma lipid oxidation, antioxidant status, and gene expression of SOD, GPx, CAT, and NRF2 in the liver. One hundred ninety-two 25-week-old Lohmann Whites were randomly divided into three treatments (n = 8 replicates/diet, 8 hens/replicate). The groups were fed a corn–soybean basal diet containing 0.00%, 0.45%, and 0.90% PFSO for 16 weeks. The results indicated that increasing supplementation of PFSO decreased plasma lipid oxidation (n = 8; linear, p = 0.012) and increased CAT gene expression (n = 8; linear, p = 0.001). SOD and NRF2 genes tended to increase linearly, and GPx was not affected (n = 4; p > 0.05). The CAT activity tended to decrease linearly and the SOD and GPx were not affected (n = 8; p > 0.05) by diets. Performance and most egg quality, relative weight, and length of organs did not differ among treatments (n = 8; p > 0.05). Therefore, increasing the supplementation of PFSO in the diet may have positive effects on the laying hens’ health by decreasing oxidative stress, stimulating the antioxidant defense system, and sustaining egg production and quality.

The production of olive oil results in various by-products such as olive leaves and olive pulp, which can be utilized in animal nutrition. The aim of the present study was to investigate the effects of dietary olive leaves and olive pulp on the oxidative status and fatty acid (FA) composition of broiler breast meat. A total of 120 one-day-old male Ross 308 broilers were randomly divided into 5 experimental groups: 1 control group (Cont) without supplementation and 4 experimental groups supplemented with either 5% or 10% olive leaves (OLeav5; OLeav10) or olive pulp (OPulp5; OPulp10). Blood and breast muscle samples were taken at the end of the experiment. The results showed that the addition of olive leaves or olive pulp did not significantly alter the concentration of malondialdehyde (MDA) and the antioxidant capacity of lipid-soluble compounds (ACL) in the blood or the enzyme activities of the liver. However, the antioxidant capacity of water-soluble compounds (ACW) in serum was reduced in broilers receiving 5% olive pulp or 10% olive leaves (p = 0.002). In addition, meat quality parameters were not affected by olive leaves or pulp intake, although 10% olive leaves reduced lightness (L*) (p = 0.023) and α-tocopherol concentration in breast muscle (p = 0.001) compared to control. Olive leaves and pulp intake also affected the FA profile of the breast muscle, with 5% olive pulp increasing monounsaturated fatty acid (MUFA) content (p = 0.002), while 10% olive leaves increased polyunsaturated fatty acid (PUFA) content (p = 0.015). In conclusion, supplementation with up to 5% olive leaves or pulp had no adverse effects on the oxidative status and meat quality of broilers. Full article
