Calculating a proper stocking density will determine the maximum farm profitability in broiler chickens. Choosing the stocking density implies knowing the impacts on live performance, and its interrelations with the environment and dietary nutrients. Abundant studies about stocking density run under non-commercial conditions might not indicate the best reliable information to know the farm profita ...

INTRODUCTIONAs we learn more about the negative impacts of calcium (Ca) on the availability of phosphorus (P), it highlights how little we know about Ca requirements, digestibility of Ca in ingredients, and their impact on P digestibility (Angel, 2019). These impacts can be direct or indirect through chelation with phytate, which can have a profound impact on the efficacy of phytase. Historically ...

DESCRIPTION OF PROBLEMBroilers have specific essential amino acid requirements that must be met in order to support growth, muscle development, and meat yield (Mack et al., 1999; Zampiga et al., 2018). Continued genetic selection of broiler strains focused on increasing feed intake and meat yield and improving growth efficiency will require adjustments in formulation, particularly in amino acids, ...

As global animal production has rapidly shifted towards reduced Antibiotic free, “Gut health” has become a popular expression and all-encompassing concept in the scientific community. The gastro-intestinal tract must provide a barrier function protecting against harmful environmental elements (e.g. toxins and pathogenic microbes), while simultaneously permitting appropriate nutrient ab ...

CURRENT FEEDING PRACTICES INCLUDING VEGETARIAN DIETS ARE MISSING CREATINEThe poultry industry is feeding less animal protein to broilers and turkeys today compared to just a decade ago. The use of animal protein was banned in livestock feeds in the year 2000 in Europe due to concerns over public health. The complete ban was lifted, but animal protein use remains low.Animal protein products, especi ...

IntroductionEndogenous protein loss, which links the gut physiology and protein nutrition, has proved to be an alluring subject of research for many years. Historically, the presence of undigested substances of digestive tract origin in the excretory products of animals and its relevance to the biological value of protein has long been known [1–3]. In poultry, the earliest work on the use of ...

The identification of mild to moderate gizzard erosions (GE) in more than 20- 30% of the healthy commercial broilers examined in post mortem sessions, is commonly found in several countries in the Americas and Asia.The gizzard, also called muscular stomach, is composed of a koilin (keratenoid) layer and an underlying mucosa. GE is characterised by damage in the form of erosions that can become ulc ...

DESCRIPTION OF PROBLEMBroiler diets are mainly composed of vegetable feedstuffs. These ingredients usually consist of high amount of P in the phytate form (60 to 80%). The phytate form that is found in plants is mostly unavailable to be used for broilers [1]. Phytate is negatively charged under many pH conditions, and because of this property, phytate can form complexes with positively charged mol ...
