Summary: The use of phytogenic feed additives (PFA) has been increasing to mitigate heat stress on chickens, which is caused by the rise of global temperature. Various bioactive compounds in different plant species and parts have been identified, such as polyphenols, flavonoids, antioxidants, growth-promoting and immune-modulating agents, that can improve the thermotolerance of broiler chickens. This review discusses the roles of PFA in managing heat stress and highlights common PFA used, particularly in tropical environments. It also emphasizes the importance of understanding the use of PFA in improving productivity and addressing consumers' concerns.

Summary: As the use of antibiotics has been banned or reduced in certain countries in animal industries, the search for new alternatives to antibiotics has been and will continue to be a research subject in poultry for several years. This study aimed to evaluate the effect of basil, thyme, and sage essential oils (EO) in broiler chickens' diets. The results showed that all EO-supplemented diets showed the potential to improve meat quality, but sage essential oil was more effective in altering the chicken microbiota in the small intestine and caecum.

Summary: Common feed ingredients like corn, barley, wheat, soybean meal, and canola meal are widely used for broiler chickens and pigs globally. However, there is increasing interest in exploring alternative feed ingredients to reduce dependence on commonly used ones and promote sustainable animal husbandry practices. Research has been conducted to evaluate the nutritional potentials, feeding practices, advantages, and limitations of various uncommon feed ingredients for pigs and chickens.

Summary: This study comprehensively analyzed and evaluated the use of CPC in broiler diets. The results showed that replacing 25% of soybean meal with CPC had no negative impact on broiler growth performance, while substituting 50% of soybean meal with CPC negatively affected growth and development. CPC has the potential to replace soybean meal and improve antioxidant capacity and immunoglobulin content in broilers.

Summary: The study showed that adding halloysite to the diet of broiler chickens can reduce feed consumption per unit of body weight gain and improve the utilisation of crude protein, leading to better fattening results. Additionally, halloysite supplementation can decrease water intake and excretion by chickens, as well as reduce ammonia levels in the air, thus enhancing the living conditions in broiler houses.

Summary: Due to population growth and antibiotic prohibition in animal production, the livestock industry is facing challenges in meeting global demand for meat, eggs, and dairy. Animal nutrition experts are searching for natural substitutes, such as probiotics, to replace antibiotics. Yeast, a commonly used probiotic, has shown to improve animal growth performance and health due to its high protein, amino acid, energy, and micronutrient content. However, there are challenges in applying yeast supplements and quantifying yeast content and biologically active components in yeast-derived products.

Nanopore sequencing shows high correlation with bisulphite sequencing in identifying DNA methylation marks. Different sequencing methods highlight differentially methylated genes and positions of economic interest in animal breeding.
