1. Introduction Recent trends in food animal production emphasize reducing antibiotic use due to the growing threat of antimicrobial-resistant bacteria [1,2]. Consequently, there is a critical need for sustainable alternatives that promote growth and health while maintaining production efficiency. Phytobiotics are plant-derived compounds that have emerged as promising candidates for this role [3]. Unlike antibiotics, phytobiotics do not contribute to antimicrobial resistance or...

1. Introduction Intestinal health is a crucial parameter in ensuring the health of birds and the optimal use of nutrients because of its various functions, namely the digestion and absorption of nutrients, the secretion of mucins and immunoglobulins, and selective protection against pathogens [1]. This topic has gained even more interest in poultry production because of increasing demands for economic efficiency, animal welfare, food safety, reducing environmental impact, and...

1. Introduction Broiler chicken feed represents approximately 75% of production costs, a figure that is expected to increase due to the commodity nature of animal feed ingredients, especially soybean oil, a primary raw material in feed production [1,2]. Currently, there are few alternative energy sources to soybean oil available for reducing production costs in poultry farming. Given these challenges, there is a growing need to explore alternative energy sources in broiler...

1. Introduction The misuse and overuse of antibiotics in humans and livestock animals are primary drivers of antimicrobial resistance [1,2], which is projected to become the leading cause of global human mortality by 2050 [1]. Consequently, the subtherapeutic use of medically important antibiotics for growth promotion and disease prevention in livestock has been banned in an increasing number of countries; however, this ban has inadvertently increased the risk of infections in...

1. Introduction Eggs and meat from poultry are indispensable protein sources in people's meals in Bangladesh [1]. However, the advancement in the poultry production is often interrupted by the overwhelming occurrence of infectious diseases in low resource settings of developing countries such as Bangladesh. Occurrence of these diseases, which incur a colossal loss due to less production of a quality product and also from the treatment cost, are attributable to noncompliance...

1. Introduction Influenza A virus (IAV) is an enveloped RNA virus, a member of the Orthomyxoviri dae family, and is known to infect humans, mammals, and birds [1]. The virus is subtyped based on the antigenic cross-reactivity and sequence identity of two surface glycoproteins, namely, hemagglutinin (HA) and neuraminidase (NA) [2]. Excluding the recently identified H17N10 and H18N11 in bats, 16 HA and 9NAIAV subtypes have been identified in mammals and birds to date...

1. Introduction Welfare assessment in animals has increasingly emphasized the need for objective, non-invasive measures that reliably reflect physiological and psychological states [1–4]. In this context, pupillometry (the measurement of pupil dynamics) has gained traction as a valuable tool, particularly in human psychological and neurological research [5,6]. The pupil’s diameter is known to change in response to a variety of internal and external stimuli, including...

@Dr Kotaiah Talapaneni Thank you for this comment! This is indeed a clear dilemma and we may distinguish the aim for the two different nutritional strategies. Indeed, genetic potential of broilers is continuously improving and if diets are formulated accordingly, unbelievable performances can be achieved. A feed conversion ratio of 1.35 at 40 days is commercially achieved in some regions of the world. Our research on balanced protein very clearly suggest that high balanced protein levels...

I. INTRODUCTION Modern broilers grow 5 times faster on 40% less feed than they did 60 years ago (Zuidhof et al., 2014). Because high body weight (BW) correlates negatively with reproduction and health (Decuypere et al., 2010), the severity of broiler breeder feed restriction increases every year relative to broiler growth potential. This intensifies competition for feed, resulting in unequal distribution of feed and poor flock uniformity. Achieving and maintaining high flock...

I. INTRODUCTION Whole grain feeding (WGF) involves the partial substitution of ground grain with whole grain in boiler diets. Whole grain (WG), usually wheat, may be added either prior to (prepellet) or following (post-pellet) steam-pelleting. WGF generates heavier and presumably more functional gizzards, which are thought to be the genesis of responses in feed conversion ratios (FCR) and energy utilisation (Liu et al., 2015). However, post-pellet WGF also provides broilers with the...
