Introduction Routine supplementation of dietary Cu, as well as other trace minerals, is intended to prevent deficiencies that originate from the lack of sufficient amounts of this micromineral in the feeds. Copper sulfate (CuSO4) is traditionally utilized as the source Cu of supplementation in poultry feeds because of its wide availability and low cost (1). Total supplemental Cu in commercially formulated broiler feeds is variable, as can be observed in the...

In 2023 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 152 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3), and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit. Contamination in animal feed 152 feed samples collected, and 77% were contaminated with fumonisins ( table 1 ). The maximum concentrations of aflatoxins,...

Dear Dr. Ivey. It's always a pleasure to read your comments, especially the ones related to the use of mathematical modeling. I do understand (at least I hope) the concept you put forward on how to establish impact of enzymes on individual ingredients' nutritional matrix. I think it might work reasonably well as long as we are dealing with very simple diets. As we increase the number of ingredients (energy/protein supplying ones) the proposed mathematics proposed becomes quite...

The enzyme products that have been developed are of great value to the broiler producer. We know commercial enzyme products release nutrients from the bulk ingredients that make the ingredients more valuable. Typically, a successful product improves value well beyond its cost. And we know that enzyme products named for the same enzyme can have other beneficial enzymes from the fermentation process that make them different, as well. The best way to use an enzyme product would be to know how...

INTRODUCTION Salmonella spp. is the second most prevalent zoonotic pathogen in the European Union, and strictly related to poultry production, responsible for 60,050 human gastrointestinal infections during 2021 . In terms of the most significant serovars, Salmonella Enteritidis and Salmonella Typhimurium accounted for approximately 54.6% and 11.4% of the reported cases, respectively. However, salmonelosis can be...

As the global poultry industry has grown and developed, a great variety of consumer products has emerged, focused on convenience and practicality, that provide opportunities to regain value from carcass parts that may have otherwise gone to waste.
During poultry processing, novel products such as fresh sausages can be an alternative use for compromised meats, such as those affected by deep pectoral myopathy (DPM), a recurrent problem in the pectoral (breast) muscles of birds...

Dietary alfalfa may improve broiler growth, but fiber inclusion may be detrimental during coccidiosis challenge.
Alfalfa is a source of health-promoting bioactive compounds (phytochemicals) that may offer several benefits to the poultry industry by direct action or by influencing the microbial communities in chickens.
Iowa State University researchers recently examined the role late-cutting alfalfa — either as ground hay or a lipid-soluble extract — may have on...

Commercial egg laying operations can benefit from more effective and economical ways to depopulate flocks at the end-of-lay while improving worker performance and maintaining or improving animal welfare. Recent on-farm research in Switzerland applied portable blue light units and specialized crate carts, seeking to improve depopulation during catching, carrying, and crating without changes to flock housing or other infrastructure. However, neither the blue light nor the cart reduced layer...

I. INTRODUCTION Exogenous enzymes are susceptible to denature when exposed to low-pH conditions, normally prevailing in the gastric phase. Hence, resistance to low-pH is considered one of the key criterion for the suitability of commercial phytase enzymes for animal feed application. The pH-stability is assessed in-vitro by measuring the recovery of enzyme activity after exposing enzyme protein to low-pH buffers. To mimic gizzard conditions, pH 2.5-3.5 with added pepsin is often...

I. INTRODUCTION Salmonellosis remains one of the most frequent food-borne zoonoses, constituting a worldwide major public health concern. Although Salmonella can be acquired from a range of foods, poultry meat and eggs remain prominent (Antunes et al., 2016). Human salmonellosis cases in the US are estimated at 1.35 million per year (Centers for Disease Control, 2019a). Likewise, cases in the UK and EU have not changed significantly over the past decade. Success in controlling...

@dan hofer As long as full fat soybeans are properly heat-treated, there should be no difference between them when balanced for different macronutrients content. And it shouldn’t be too much different than using SBM plus oil. Actisaf would not be expected to work differently because of different soy protein source....

I. INTRODUCTION The continuous genetic improvements are increasing the first commercial egg size produced and extending the production life of the layer hens worldwide. These improvements are related to what happens at rearing and at the start of the production. Early studies showed that while approximately 60 to 75% of the calcium destined for the shell comes directly from intestinal absorption (Driggers and Comar, 1949), up to 36% could be traced to bones (Mueller et al., 1964)....

I. INTRODUCTION Necrotic enteritis (NE) in broiler chickens is an economically important disease which can be controlled by antibiotics (Timbermont, et al., 2011). The occurrence of necrotic lesions in the small intestine is associated with proliferation of Clostridium perfringens, which leads to lower growth rate in subclinically infected chickens. Increasing concerns regarding antibiotic resistance and the presence of drug residues in animal products have led many countries to ban...

I. INTRODUCTION A hen’s physiological patterns including FI and BW trajectory are established by early lay (Muir et al. 2022). Therefore, management tools such as lighting and feeding programs during rearing may offer opportunities to regulate bird size and establish feeding habits by the end of rearing. This may also influence persistency of lay, egg quality and hen health during an extended laying period. The lighting program during rearing can modify bird age at sexual...
