I should like also to comment from Dr. Marchenkov regarding "vegetable methionine". As Dr. Wu correctly states, methionine is methionine; an amino acid with a clearly defined structure INDEPENDENT of the source. I have seen numerous products claiming to be "Herbal methionine" and these materials are not methionine, and do not contribute methionine. When used in correctly balanced and formulated diets, they invariably result in reduced animal performance. They will only work in diets that...

I. INTRODUCTION Broiler diets are formulated on the basis of ideal protein ratios (IPR) where selected amino acid requirements are expressed relative to lysine (100). However, IPR have been developed over decades for standard diets rather than diets with reduced-CP. This has led to the possibility that reduced-CP diets require modified IPR. For this reason, two sets of ratios were evaluated in diets with 210 and 180 g/kg CP in a 2 × 2 factorial design. II....

I. INTRODUCTION Phytases have been heavily researched for decades and been used commercially since the early 1990s). Phytase from microbial origin is therefore added to monogastric diets as it can reduce the incorporation of inorganic P sources in the feed, reducing feed cost and P excretion in the environment. Phytate is the main storage form of phosphate in plant matter and in vegetable feed ingredients where it can normally be found in concentrations of 5 to 25 g/kg (CVB,...

Allowing poultry access to vegetated, woody spaces will benefit poultry welfare. One system that incorporates the production of vegetation and livestock, including poultry, is called a silvopasture system. Woody vegetation can provide a source of income for producers while providing preferred habitat for chickens. Silvopasture...

Introduction There is a mandatory requirement for crude protein (CP) in broiler chicken diets ranging from 180 to 230 g/kg. When dietary energy density is not limiting, the quality and quantity of dietary CP dictates birds’ growth performance. The digestibilities of protein and amino acids are pivotal to the quality of the inclusion of any feedstuff in diets for chicken-meat production. However, a series of studies [1–3] have demonstrated that feed conversion...

Laying hens are female chickens raised for egg production. The egg production system in the US is currently undergoing a transition from conventional cages to cage-free housing systems. The number of cage-free housing has increased from 4% hens in 2004 to 28% at the end of 2020 (USDA-NASS, 2021). Cage-free systems provide space...

1. Introduction The mucosal lining of the small intestine is a highly functional epithelium comprised of absorptive, secretive and sensory cells, which are constantly renewed by multipotent intestinal stem cells (ISC). ISC reside within crypts, and constantly proliferate for self-renewal and generation of progenitor cells, which differentiate into the functional cells that line lumen-facing villi (Carulli et al., 2014; Potten and Loeffler, 1990). Compartmentalization of the...

1. Introduction The occurrence of ‘wet litter’ in meat chicken sheds is associated with concerns regarding animal welfare, flock health, food safety, environmental impacts and reductions in production efficiency. Mitigating wet litter will only be achieved when there is thorough understanding of the multidimensional causal factors. This will require a multidisciplinary approach to understand the hydrology in the meat chicken shed micro-environment; the biological...

Switching from blue to red light in laying operations may benefit birds, but there are caveats
According to new research in The Journal of Applied Poultry Research , hens can benefit from both blue and red light—if these lights are provided at specific points in production. The study, led by scientists at Mississippi,...

Poultry scientists find hens prefer lower UVA/B light
A new Poultry Science ® study suggests hens do like sunlight—just not too much. In fact, by monitoring hen behavior under different strengths of UVA and UVB light, the researchers found that hens prefer to spend more time in lower levels...

New research shows the power of vaccination plus feed additives for birds facing intestinal parasites
Necrotic enteritis (NE) can strike young birds seemingly out of nowhere. The disease, which is driven by bacteria and marked by lesions in the gastrointestinal tract, can lead to massive flock mortality.
Poultry scientists have found that flocks can be predisposed to NE when they are...

1. Introduction Mycoplasma gallisepticum (MG) is highly pathogenic and causes infections in poultry that result in significant economic losses in commercial poultry operations worldwide [1–4]. An MG infection causes avian respiratory mycoplasmosis, which can lead to chronic respiratory disease in chickens and infectious sinusitis of turkeys, with subsequent increases in mortality and reduced growth rates [3,4]. It is well known that field strain MG infections reduce table...

INTRODUCTION Least cost feed formulation relies on the assumption of additivity of digestible nutrients from the contributing ingredients. It is generally accepted that assessment of the nutritional value of individual raw materials underestimates their eventual contribution in a complex diet because of the often-substantial influence of endogenous loss. The premise is that a proportion of nutrients that leave the terminal ileum are inevitable (or “basal”) losses and...

Hypothesis Guanidinoacetic acid (GAA) is synthesized in the liver and kidneys from arginine (Arg) and glycine (Gly) and subsequently methylated by S-adenosylmethione to creatine (2). Heat-stressed birds respond to the presence of higher uric acid concentration and changes in electrolyte balance by increasing the usage of osmoprotectants. These osmolytes are viable endogenous precursors for Gly (3). On the other hand, high supplemental lysine level on modern genetic broiler...
