While poultry manure has served as a convenient and inexpensive fertilizer source for many Alabama farmers, little is known about where those nutrients and minerals go once they pass through the soil.
Of special interest to a group of Auburn researchers is the...

Dietary fat and oil are potential alternative energy sources for fast growing broiler chickens (Meng et al., 2004). Nevertheless, hampered fat digestion and absorption were reported in young broiler chickens with incompletely developed digestive tract (Al-Marzooqi and Leeson, 2000). Addition of emulsifier and lipases to a diet is one strategy to improve energy utilization and subsequent growth performance in broiler chickens when fed a high fat diet (Siyal et al., 2017). Studies...

Environmental factors encountered during pre-natal life influence the developmental trajectory of a developing embryo, altering post-natal phenotypes (Du et al., 2015). Maternal nutrition and stress directly influence the maternal environment, with both factors prominent in the broiler breeder industry. Broiler breeders are feed restricted to improve reproductive output; however evidence suggests hens suffer from chronic stress due to prolonged hunger (Mench, 2002). Feed restriction in...

Phytate is a polyanionic molecule with the capacity to chelate Ca, forming mineral-phytate complexes. The presence of these complexes decreases the efficacy of phytase. Ca-phytate formation is dictated by molar ratios of the constituents, gastrointestinal pH and the concentration of dietary Ca relative to P (Sommerfeld et al., 2018). The hypothesis of this study was that a high dietary Ca to P ratio will reduce the ability of phytase to hydrolyze phytate, which will exacerbate necrotic...

I. INTRODUCTION The concept of “fast” and “slow” proteins in human nutrition was enunciated by Beaufrère et al. (2000) and consideration has been given to protein and starch digestive dynamics in poultry by Liu and Selle (2015). However, the digestion rate of protein has a greater bearing on broiler growth performance than that of starch (Liu et al. 2014). Thus, the objective of this experiment was to compare the effects of ten nutritionally...

Necrotic enteritis (NE) is a poultry disease of global concern mainly due to reduced growth, increased mortality, and increased veterinary and management costs associated with it (Wade and Keyburn, 2015). Clostridium perfringens , a spore-forming gram-positive bacterium, is considered to be the causative agent of NE in chickens. In the past, the common remedy to ameliorate the negative effects of NE was an addition of antibiotic growth promoters (AGP) in feed. However, with AGP...

Antibiotics in feed have been effective in controlling the prevalence of necrotic enteritis in broilers. However, the occurrence and severity of C. perfringens -induced necrotic enteritis has increased over the years due to the banning of the use of antibiotics in food-producing animals. Thus, the poultry industry is in urgent need of alternative strategies to prevent necrotic enteritis in broilers. Probiotics have become the ideal alternative to antibiotic growth promoters....

I. INTRODUCTION Oregano essential oil contains many compounds, of which carvacrol, thymol and their precursors are the major components, accounting for approximately 80% of the contents. Carvacrol and thymol have been shown to actively disrupt the cell membranes of bacteria leading to cell death, promoting the use of oregano as a phytobiotic (Rao et al., 2010). Phytoadditives such as oregano are becoming more popular as organic and natural alternatives to antibiotics....

Poultry farms act as an important source of transmission of antimicrobial-resistant (AMR) Salmonella to the environment as well as to humans. Indiscriminate and prophylactic use of antibiotics in poultry farms is one of the reasons behind it. Therefore, a cross-sectional study was conducted to determine the prevalence of Salmonella in broiler chickens, farm environments, as well as farmers to identify the risk factors for Salmonella colonization in broiler farms....

1. Introduction It is well known that female and male broilers chickens are separately reared in the Italian production system, as the consumers seek three different market classes of birds: the so-called light-, medium- and heavy-size broilers. In particular, heavy birds are male broiler chickens that reach 3.4–3.6 kg of live weight during 54–58 day rearing cycles, in order to provide carcasses around 2.5- to 2.6-kg for the production of cut-up and further processed...

1. Introduction To preserve the potency of clinically important antibiotics, there has been a gradual reduction and an anticipated elimination of their use in food-producing animals including broiler chickens [1]. Consequently, farmers are faced with the challenge of maintaining productivity and preventing diseases on their farms [2]. Therefore, there is a need for alternative strategies including dietary means to promote gut health and growth performance of broiler chickens....

The common bed bug (Latin name Cimex lectularius) is part of a group of blood-feeding parasites called Cimicids. The common bed bug was mostly eradicated in North America in the 1960s. Then, in the 1990s, large cities such as New York, Chicago, Cincinnati, Toronto, Montreal and Winnipeg saw a rise in bed bug infestations that spread throughout the U.S....
