Introduction Maternal nutrition during gestation and early life events impact offspring development throughout life, in a phenomenon known as developmental programming. The Barker hypothesis explains that undernutrition during specific developmental periods in pregnancy can create a scenario of pre- and post-partum metabolic mismatch (Hales and Barker, 2001). Metabolic mismatch occurs when offspring of undernourished cows are ‘programed’ to expect limited nutritional...

The importance of vitamin nutrition in poultry feeding has been recognized for decades, yet precise vitamin requirements for modern, high producing have not been investigated. Because of their low inclusion rates, vitamins have a relatively small impact on the cost of feed. Many vitamins lose activity over time or under high-temperature feed processing. Vitamins, especially the water-soluble vitamins, are tolerated at many times the established minimum recommended levels. Finally, the...

Background Porcine epidemic diarrhea virus (PEDV) is an enveloped single-stranded positive sense RNA virus belonging to the Order Nidovirales, the family Coronaviridae and the genus Alphacoronavirus (Saif et al. [1]). Following detection in the US swine population during May, 2013, the virus spread rapidly across the country and 6317 cases of Porcine Epidemic Diarrhea (PED) have been confirmed in 29 states as of May 3, 2014 [2,3]. While little information is known regarding the...

INTRODUCTION The global production of chicken eggs is constantly increasing, e.g., 37.4 million tons of chicken-eggs were produced in 1990, and 80 million tons in 2018. The WHO has estimated that production will have to increase four-fold to meet the global demand for chicken eggs in the next two decades (1, 2). Hence, the poultry industry must be increasingly efficient despite being one of the most efficient and technologically advanced animal production activities...

INTRODUCTION Cereal grains such as wheat, sorghum, barley, and corn are commonly used in poultry diets as major sources of energy. Knowledge of the ME content of cereal grains is critical for their efficient and sustainable use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME is the globally accepted system for describing the available energy for poultry (Hill and Anderson, 1958; Sibbald, 1982). The simplicity,...

1. Introduction Often a seemingly straightforward aspect of nutrition reveals itself to be, upon closer inspection, not so simple after all. An illustration of such a conundrum is the nutrition of the newly hatched broiler chick. Conceptualizing the different challenges faced by the hatchling and solving them should be remarkably simple, but the difficulty lies in the complexity in the development of the gastrointestinal tract (GIT), digestive physiology, immune system, and...

1. Introduction Available energy in feed or feed ingredients for poultry can be measured by different systems, with the apparent metabolizable energy (AME) [1], despite its limitations [2,3], being the commonly accepted and extensively used system. Three methods, namely, direct, substitution (or difference), and regression, have been used to determine the AME of ingredients for poultry. In each method, the excreta can be collected by total collection, which is the...

The fish protein hydrolysate market from pet food and animal feed application is anticipated to attain lucrative revenue growth on account of growing prevalence of food-borne infections and diseases among animals. Consumers are adopting high protein diet for their pets and animals to safeguard them from potential diseases.
Rising imposition of stringent regulations on waste disposal could have a positive impact on the market. Governments around the world are ensuring the safe...

Increasing efforts towards animal health and wellbeing will foster the demand for alternative proteins in animal feed. The growing intake of meat and animal products has encouraged farmers as well as solution providers to incorporate various affordable feed management strategies for the betterment of animal health and the environment. There is also a surging need for protein-rich and nutritious foods in order to reimagine the global food system security.
This has paved the way for...

A study was conducted to investigate the hypothesis that over-processing (OP) of meat and bone meal (MBM) exacerbates infection with necrotic enteritis in normal and high phytase diets. A total of 768 Ross 308 male chicks were randomly assigned to 8 treatments with 6 replicate floor pens each housing 16 chicks using a 2 × 2 × 2 factorial arrangement of treatments for 42 d. Factors were: NE challenge, no or yes; phytase* level, 500 or 5000 FTU/kg (both using 500 matrix values for...

A feeding study was conducted to examine the efficacy of a synergistic blend of feed additives on growth performance, livability, gut integrity, immunity, caecal microflora and footpad health in broilers challenged with subclinical necrotic enteritis (NE). Additives were: A) synergistic blend of medium chain fatty acids (MCFA), slow-release C12, target release butyrates, organic acids (OA) and a phenolic compound; B) synergistic blend of partly buffered OA with MCFA; C) synergistic blend of...

Probiotics are showing promise as antibiotic replacements but more scientific evidence is required to validate their beneficial effects. Previous broiler feed trials conducted with Bacillus amyloliquefaciens strain H57 (H57) indicated variable bird performance (Bajagai, 2018). In these trials, birds were kept under “optimal” experimental conditions, where most of stressors were absent from the environment. There is some evidence that probiotics are best applied when a bird or...
