“…Unsurprisingly, the CTA decreased and increased blood cholesterol and HDL, respectively, in our research. Similar outputs were observed when layers are supplemented diets with herbal medicine at standard temperature (Abd El‐Hack et al, 2020, 2021; Hosseini et al, 2021; Kothari et al, 2019; Seidavi et al, 2020). The effect of herbal medicine on the blood biochemistry of HT‐farmed poultry was also well‐investigated.…”

At some stage, laying hen farming is likely to be subjected to sub‐optimum temperatures (SOTem) due to climate change. While egg enrichment with n‐3 fatty acids is a common practice in the poultry industry, in SOTem it has been less investigated. This study tested the effects of egg enrichment through extruded flaxseed (FLX) (180 g/kg) alone or along with hulled‐soaked barley (H‐SB) (170 g/kg), namely FLBA, with and without a cold‐temperament additive mix (CTA) (25 g/kg: 5 g/kg flixweed (Descurainia sophia), 10 g/kg dried herb‐extraction residues from pussy willow (Salix aegyptiaca) and 10 g/kg dried lemon (Citrus limon) residue) in two temperatures (20°C and SOTem: 27°C) on egg performance, yolk fatty acids, lipid components, blood biochemistry, serological enzymes, antioxidant and immune system of Hy‐Line W‐36 53‐week‐old for 9 weeks. Two hundred seventy layers were randomly distributed to nine treatments, resulting in six replicates with five hens. Hens fed flaxseed diets, regardless of temperature or CTA, had higher levels of n‐3 fatty acids in yolks than others. Temperature negatively influenced feed intake and egg production. FLX + H27 and FLBA + H27 groups outperformed the other groups regarding cholesterol in yolk (10.1, 10.3 mg/g yolk), high‐density lipoprotein (HDL) (5.19, 4.93 mg/g yolk), total protein (FLX + H27: 6.82 mg/dl), HDL in the blood (FLBA + H27:83.8 mg/dl), superoxide dismutase (FLBA + H27:90.4 U/ml), glutathione reductase (FLBA + H27: 1042.1 U/ml), glutathione peroxidase (FLX + H27: 1149.7 U/ml) and catalase (FLBA + H27: 12.5 U/ml). Total antibody, immunoglobulin G and immunoglobulin M after 42 days were significantly higher in chicks fed CTA‐added diets (p < 0.05). Replacing corn and soya bean meal with H‐SB did not negatively change the above‐mentioned factors. Our findings collectively suggest that egg enrichment with n‐3 fatty acids through dietary FLBA + H27 (180 g/kg flaxseed, 170 g/kg H‐SB, and 25 g/kg CTA) in SOtem is suggested without any adverse impacts.

Modern commercial breeding programs aim at maximizing productive performance, especially with modern broiler chicken strains, which are characterized by a high growth rate and a lower feed conversion factor. However, it is more sensitive to environmental stress, intensive rearing conditions, and high nutritional needs. Nutrition plays a key role in achieving the maximum amount of production while maintaining the health of the bird, in addition to reducing production costs by searching for unconventional feed ingredients or using some feed additives. Feed additives are mainly used in animal feed to help provide for the bird’s needs. In addition, it is used to enhance bird health, stimulate digestion, improve feed efficiency, and resistance to diseases by positive influence on the gastrointestinal tract, metabolism, and enhancement of the immune system, inhibiting pathogens, and improving intestinal integrity. In broiler nutrition, special attention should be paid to feed additives of modification of immunity and microbial content such as pre-and probiotics, nano compounds, herbs. In this chapter, we will elucidate the importance of feed additives from the point of marginal environmental conditions, which face many challenges concerning poultry feeding. Hence, feed additives will be a fruitful tool to cope with some of such challenges under those marginal conditions.
