This review mainly focuses on the effects of olive pomace inclusion in animal feed on milk production, growth performance, nutrient digestibility, feed efficiency, and health status of the animals. Overall, dietary olive pomace resulted in satisfactory response of the animals in terms of its addition in diets as a cheap nutrient source and improved quality of animal products.

The present study evaluated the effects of fennel seed meal (FSM) on performance, carcass characteristics, lengths of digestive tract parts (cm), intestinal enzyme activity, intestinal microbiology, blood parameters, and economic efficiency in broiler chickens. It is concluded that fennel seed meal can be used in up to 20 % of broiler chicken diets to reduce feed costs without adverse effects on broilers' growth performance and public health.

This study evaluated the impacts of selenium nanoparticles (SeNPs), zinc oxide nanoparticles (ZnONPs), and a combination of SeNPs and chromium (Cr) or ZnONPs and Cr on growth, caecal microbiota, antioxidant capacity in blood and liver tissue, and inflammatory cytokines in heat-stressed rabbits. SeNPs or ZnONPs with chromium can be recommended as an effective intervention to mitigate the negative impacts of heat stress by enhancing growth and immunity and promoting metabolic processes.

The goal of the current study was to determine how dietary black pepper oil (BPO) supplementation affected growth performance, characteristics of growing quails' immunity, antioxidant status, and carcass yield. In conclusion, dietary BPO supplementation in Japanese quails' diet can boost growth performance and antioxidant indices, enhance lipid profile and carcass traits, and reduce intestinal infections.

It was suggested that the start codon targeted (SCoT) markers may be more effective than inter-simple sequence repeat (ISSR) for differentiating and identifying the genetic variations within investigated breeds. Also, the usage of molecular markers of SCoT and ISSR may be more proper for calculating genetic diversity and common ancestry among tested rabbit breeds.

The present study aimed to evaluate the impact of dietary lysozyme levels on the growth performance, hematological and blood biochemical parameters, immunity, antioxidant capacity, and intestinal microbial count in broiler chickens. In conclusion, chicken egg lysozyme (50 mg kg−1), a promising alternative for antibiotics in broiler chickens' diet, can enhance growth performance, antioxidant status, immunity, and intestinal microbiota.

This study aimed to show the effect of bile acid (BA) and xylanase (Xyl) supplementation on growth, fat digestibility, serum lipid metabolites, and ileal digesta viscosity of broilers fed wheat and tallow in their diets. The results of this trial revealed that the supplementation of Xyl significantly reduced the ileal digesta viscosity, and the supplementation of BA significantly increased the attention of serum lipid metabolites.

This trial was performed to determine the effect of anise (Ans) and grape seed (Grp) oil inclusion in diets of Japanese quail on performance, carcasses, blood parameters, antioxidant activity, and hematological blood structure. It is concluded that Ans and Grp seed oils could be used as valuable essential oils in quails’ diets to stimulate the performance and immune response, enhance antioxidant activity, and reduce caecal pathogenic microbes.

Short summary
In the production of chicken, phytobiotics have the potential to replace antibiotics. This experiment was carried out to investigate the impact of phytogenic feed additives (NUQO©NEX) as a natural growth promoter on growth parameters and economic efficiency measurements. Broiler chickens fed a diet supplemented with NUQO©NEX showed positive effects on the overall performance, cholesterol, antioxidant status and immune state, carcass quality traits, and economic effectiveness measurements.
