INTRODUCTION Since the use of antibiotic growth promoters was banned by the EU on January 1st, 2006, several feed additives have been studied as alternatives to antibiotics, such as probiotics, prebiotics, synbiotics, and herbal medicines (1). Among these feed additives, prebiotics have been studied and supplemented broadly into broiler diets in recent years. Gibson and Roberfroid (2) defined a prebiotic compound as a non-digestible food ingredient utilized by intestinal microbiota....

@M.C. Fernando R. Feuchter A. Vinegar is a very weak acid and a great source of carbon for certain molds, yeasts, and fungi to use as a carbon source for food and growth. My question would be, what is the reason for using it when flushing lines? If it is to lower the pH so the chlorine is more effective, I would be surprised if it is actually lowering the pH, and if they are using it to descale the water lines, it will never be strong enough to do that properly (if there is a substantial amount...

INTRODUCTION In South Africa and worldwide, the poultry sector contributes immensely to the global food security status of consumers (1). According to the Food and Agriculture Organization (FAO) (2), the demand for poultry feeds is increasing due to the high growth of commercial and smallholder poultry enterprises. Moreover, in the poultry sector, feed accounts for approximately 60–80% of the total cost (3), with fish and soybean meal used as the main protein sources. However,...

@Mike Stahl Dear Mike. Actually, trials demonstrate the same bioefficacy level in all types of livestock, including Laying hens. There are numerous laying hen experiments - both in field conditions and at research facilities - confirming that 100 parts of MHA can be replaced by 65 parts of DL Methionine with no loss in performance but significant savings in feed cost. I can share these with you if you supply your email address, or alternatively you can contact your local Evonik guy....

Cordyceps militaris is a well-known Chinese medicinal fungus that has been used as a nutraceutical food in several Asian countries. Cordycepin (3’-deoxyadenosine), a secondary metabolite produced from Cordyceps militaris has been demonstrated to exert a wide spectrum of pharmacological activities, such as anti-microbial and antitumor activities. However, the effect of cordycepin on immunomodulation in broilers is poorly investigated. In the current study, we...

INTRODUCTION The poultry industry in Brazil has gained worldwide prominence and has experienced a major evolution in the technological aspects related to the production of broilers. In 2016, Brazil produced 12.9 million tons of chicken meat, which ranked second in terms of world production (ABPA, 2017). According to the FAO, from 2000 to 2030, the world will have to increase the meat production by 20%, and the greatest potential growth will be in chicken meat...

1 INTRODUCTION Modern broilers grow three to four times as quickly as earlier generations (Browning & Cowieson, 2013). Leg disorders, bone weakness, and broken bones are common problems in broilers that are attributed to poor growth, downgrading at slaughter, and reducing the bird’s routine activities, such as walking, standing, eating, and drinking subsequently causing economic loss at the end (Bell & Weaver, 2002; Manohar et al., 2015; Meseret, 2016;...

INTRODUCTION Listeria monocytogenes is a Gram-positive, facultative anaerobe that is the causative agent of listeriosis (Gudbjörnsdóttir et al., 2004). They are considered saprophytic organisms with the capability to adapt to an ever-changing environment because they possess multiple stress response mechanisms to overcome varying temperatures, salt concentrations and pH (Berrang et al., 2000; Milillo et al., 2012a; Giaouris et al., 2015; Saldivar et al., 2018). Listeria...

INTRODUCTION Global population growth, along with rising affluence in Asia, are driving up not only our total demand for food, but also the amount of protein required to feed all of humanity (1, 2). More specifically, the world’s population is expected to grow to over 9 billion people by 2050, and demand for poultry, which represents a relatively healthy and efficient source of protein, is likely to be double from what it was in 2005. At the same time, it is expected that...

I. INTRODUCTION The nutritional strategy of reducing dietary crude protein (CP) in broiler diets to improve the sustainability of poultry production has been widely reviewed in the recent years (Hilliar and Swick, 2019; Selle et al., 2020). This strategy has proven benefits on global warming potential (GWP; Kebreab et al., 2016; Cappelaere et al., 2021) and litter quality (van Harn et al., 2018). In terms of growth performance, there is still a controversy on the ability of...

I.INTRODUCTION A high degree of volatility with regard to the pricing and supply of inputs has arisen. This situation began with the COVID-19 pandemic and the negative effect it had on the global supply chain, and has been exacerbated by the Russian-Ukrainian war. This state of affairs will likely persist until at least the end of 2023 (Mulder, 2022). It has given rise to the intermittent non-availability of several essential feed ingredients. Coupled with these short- to medium-term...

I. Introduction In Australia, 95% of the population are concerned about animal welfare with 91% desiring better ways to monitor and improve animal welfare (National pest & disease outbreaks, 2018). There is increased understanding and focus on animals’ sentience and the need to ensure farm animals have ‘lives worth living’. This applies to the Australian egg industry where research shows the community believes that hens are entitled to positive and rewarding...

I. Introduction Early life experiences play an important role in the behavioural development of laying hens (Janczak and Riber 2015; Nicol 2015). Environmental differences in rearing systems have been shown to have an impact on behavioural problems such as feather pecking and cannibalism during adulthood (de Haas et al. 2014; Riber and Guzman 2017). In addition, fearfulness early in life has been shown to correspond to increased stress response in adulthood (de Haas et al. 2012). A...

I. Introduction Immediately after birth, or hatch in birds, the initial inoculum shapes the gut microbiota for life. The first bacteria to settle in the intestine can attach to epithelial cells with no competition, rapidly establish, grow, and set the intestinal environment to suit their own needs (Stecher and Hardt, 2011; Edwards, 2017). The first bacterial settlers have the most substantial influence on developing the host's immune system and overall ability to thrive (Stecher...

I. Introduction A consistent definition of aging was presented by DiLoreto and Murphy (2015). According to these authors, aging is the result of the non-functionality of the animal's cells, tissues and organs, caused by the stochastic degradation of its parts. This definition considers the changes that have occurred in laying hens that affect the rate of lay (Gu et al. 2021a, 2021b). The main changes are related to the digestive, reproductive system, endocrine glands and...

INTRODUCTION Corn is one of the major components of poultry feed, and up to 65% of finished poultry feed can be comprised of corn and corn byproducts (Alqaisi et al., 2017). Poultry diets are often contaminated with more than one mycotoxin. Fumonisins (FB) and deoxynivalenol (DON) are secondary mycotoxin metabolites produced by Fusarium verticillioides and Fusarium graminearum, respectively (Glenn, 2007). According to the 2021 survey by Biomin, FB and DON are the most prevalent...

1. Introduction In resource-limited settings, there is a high usage of antibiotics in food-producing animals for preventive, metaphylactic, therapeutic, and growth promoters, especially with the modernization and commercialization of the poultry industry [1–3]. The misuse of antibiotics has been regarded as a major driver of antimicrobial resistance [4]. In addition, it poses a risk of zoonotic transmission as humans may acquire antibiotic-resistant bacteria from animals,...

INTRODUCTION Poultry meat is currently the world’s most consumed and affordable meat type among animal-source. For the coming decade, per capita consumption of poultry meat is expected to increase by 5.5% worldwide, highlighting the importance of this commodity to food security, and protein availability (1). However, consumption of contaminated poultry meat was reported to cause 20.6% of foodborne diseases in the US between 1998 and 2008, among which Salmonella spp. was one of...
