According to monitoring data provided by the China Veterinary Medicine and Feed Trading Center, the price index of major veterinary APIs is operating smoothly with relatively little volatility in the market price. Heat and humidity are unfriendly to the production of some varieties of APIs. Factories have recently arranged seasonal shutdowns for maintenance. It is expected to result in a tight supply of the related raw materials in the short term. Heavy rains and floods in northern...

When it comes to poultry feed, particle size makes a big difference for bird nutrition.
Research shows that chickens increase their feed intake and performance when given pelleted feed or crumbled pellets, compared with mash.
This has led researchers to wonder whether feeding crumbles could jumpstart very early chick growth and boost final broiler body weights. It is important to study this question because pellets and crumbles are more...

Properly cooking poultry products is key to avoiding bacterial infections such as Campylobacter, so there are concerns that the recent popularity of undercooked chicken livers, often served as a pâté, could lead to foodborne illnesses.
Poultry scientists are curious whether the same concern is relevant for turkey livers—an important question as turkey consumption continues to grow in the United States.
To better...

The issue of antibiotics resistance on animals has raised concerns about meat safety and human health. The banning of antibiotics- growth promoter in animal feed was announced in the EU in 2006. Other countries are starting to follow the regulation to comply with the compulsory withdrawal periods to ensure ‘antibiotics free products. Supplementation in nutrients to enhance the immunity system and lower the risk of the pathogen can help to reach the balance between maintaining animal...

1. Introduction A previous study reported nontyphoidal Salmonella spp., Clostridium perfringens, Campylobacter spp., and Escherichia coli as some of the most important foodborne bacterial pathogens in the U.S. [1]. Overall, health-related cost associated with the food borne illness from those pathogens was estimated to be around $51.0 and $77.7 billion based on a basic and enhanced model, respectively, as described earlier [1,2]. S. enterica serotype Enteritidis (SE) that...

Introduction A 42-year history of information on Salmonella enterica serotypes indicates it is essential to rapidly determine serotype and subtype of isolates from contaminated products to improve the safety of food (Liu et al., 2011; Fabre et al., 2012; CDC-NCEZID, 2013; Lettini et al., 2014). Recently, a sequence-based method called dkgB-linked intergenic sequence ribotyping (ISR) became available to producers who want to independently screen for serotypes of S. enterica...

INTRODUCTION The Centers for Disease Control and Prevention has estimated there are approximately 48 million cases of foodborne illness in the United States annually (Elaine et al., 2011a, 2011b). Salmonella and Campylobacter are the most frequently reported bacterial causes of poultry-related foodborne illness (Heyndrickx et al., 2002; Mead, 2002) because of their association with the gastrointestinal (GI) tract of chickens...

Background Investigations in reducing dietary crude protein (CP) in chickens began in the early 1940’s, which commenced nearly a century of exploration in this area of poultry nutrition research. Advances have been made, but many of the hurdles identified in the 1940’s vex poultry nutrition researchers today. Most notably, in the early 1940’s research was carried out in chickens fed various diets substituted with ingredients differing in protein and energy...

Introduction Endogenous 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 nitrogen-free diets was by Ackerson et al. [4] to study the variation in nitrogen...

General introduction: Newcastle disease (ND) Poultry farming is one of the most important livestock producing activities in the world because it supplies low-cost animal protein. Nevertheless, since its beginning, the main threat to the industry has been the occurrence of diseases that decrease production. One of the most common and detrimental avian viral diseases affecting poultry production is Newcastle disease (ND), caused by infections with virulent viruses from the genus...

INTRODUCTION Genetic selection in poultry has progressed continuously since the early 1960s, resulting in faster growth rates and higher meat production (Havenstein et al., 2003a,b). Over the past 60 years, body weight gain has increased fourfold from 1957 to 2005 with a simultaneous 50% reduction in feed conversion ratio and 79% higher Pectoralis major yield in males and 85% in females (Zuidhof et al., 2014). At the same time, the growth, development, structure, and...

Low protein (LP) diets have clear benefits for the poultry industry with regards to health, welfare and production. Dean et al., (2006) found that supplementing LP diets with glycine (Gly) and essential amino acids (AAs) can maintain performance similar to that seen on a standard protein (SP) diet. Further research into this concept proposes that supplementation of Gly precursors such as threonine (Thr) and serine (Ser) can overcome Gly deficiency in LP diets. Enzymes enabling these...

Due to the projections of accelerated growth of world population, it is essential to increase the production of proteins from animal and plant origin. Insects have been used as an alternative protein source for humans (entomophagy) and other animals because of their greater efficiency in food conversion and less environmental impact (Van Huis et al. 2013, Van Huis 2013, Van Huis 2020). Edible insect larvae contain an average of 54% protein, including essential amino acids and vitamin...
