This study aimed to investigate the effect of dietary supplementation with Silvafeed® ATX, vitamin E and selenium on carcass traits and blood serum metabolites of NZW rabbits under summer stress conditions. In rabbits stress associated with exposure to high ambient temperatures results in a reduced welfare of the live animal and thus a decreased performance, especially in terms meat quality. Dietary antioxidants protect rabbit’s tissues against oxidative damage, restoring...

Introduction Increased growth rate and low feed conversion ratio through genetic selection in broiler chicken has been attributed to increased body fat deposition, high mortality and high incidence of metabolic diseases and skeletal disorders (Zubair & Leeson, 1996). Excessive fat (abdominal and subcutaneous) in carcasses of broiler chickens is a waste product in...

INTRODUCTION The biogenic amines are biologically active compounds synthesized from amino acids. Feed-borne biogenic amines are most commonly synthesized by spoilage microorganisms and are usually considered to be potential toxins (Eggum et al. 1989). By-products that have undergone some degree of spoilage are generally considered to be the richest sources of biogenic amines. These would include meat and bone meal, blood...

DDGS can be used in poultry and swine feeds, provided that its quality meets nutritionist's expectations. As an industrial by-product from the ethanol industry, its composition may vary not only among suppliers but also in the course of time, depending on the cereals coming in and technological management of the plant. Therefore, we strongly recommend controlling DDGS quality as frequently as possible. NIR (Near Infrared Reflectance) offers the possibility to...

Introduction Poultry production in the past century has transitioned from predominantly breeding layers to breeding a mixture of both layers and broilers, based on the evolution of consumer demand (1–3). Success in the optimization of different broiler lines is due to genetics as well as optimizing diets with more precise nutritional formulations (4, 5). Comparison of individual genetic lines has revealed differing...

Ingredients used in animal feeds and their contamination with undesirable substances, such as mycotoxins, are fundamentally important both in terms of the quality of animal products and the potential human health impacts associated with the animal-based food production chain. Feed ingredients contaminated with mycotoxins may have a wide range of toxicological effects on animals. Therefore, mycotoxin contamination of feed ingredients constituting complete feed...

Soybean meal, or SBM, exports from the US are expected to grow by 8 million mt/year over 2016-2024, driven by strong demand from the feed industry in Asia, according to participants at the Southeast Asia-US Agricultural Cooperators conference being held at Cebu, the Philippines, over July 31-August 3.
“[About] 60% of the demand for US soybean meal is from Asia, and the growth is exponential, with projected 80 million mt increase for the next 10 years to meet the huge...

We feed our pet animals more like humans than the animals they descend from. While the ancestors of our cats and dogs were mainly eating prey animals, nowadays a label of pet food looks more like a human dinner. How did that happen? Firstly, most cats and dogs are raised in a limited living space, either completely indoors, or partly outside. Especially in densely populated areas they are kept with restricted freedom to move around the neighbourhood and...

EFSA’s Scientific Opinion 1 on Ethoxyquin as a Feed Additive was published in November 2015, when the European Food Safety Authority (EFSA) could not conclude on the safety of the feed additive for target animals, for the consumers and for the environment due to a lack of data.
Among the items discussed, the EFSA could not conclude whether ethoxyquin quinone imine (an ethoxyquin metabolite) would potentially pose a...

The regulatory framework in the feed industry is changing worldwide, particularly in Europe. In 2003, regulatory changes required that all feed additives must be evaluated by the European Food Safety Authority (EFSA), and obtain authorization to remain on the market. Under the patronage of the EU Association of Specialty Feed Ingredients and their Mixtures (FEFANA), several consortia were created, and categorized according to specific feed additive...

Nutriad has demonstrated the use of Quorum Sensing (QS) as a tool in the development of two new feed additives: one for broiler production and one for aquaculture. QS Is a form of bacterial communication that is critical to bacterial virulence. By investigating the ability of several highly bioactive compounds to inhibit QS, Nutriad was able to select a combination of components that, in in vivo models, had a positive effect on the viability of...

There are many mold inhibitor brands in the feed additives market which claim to work better than all others. However, not all of them are as efficient as suppliers might claim. What should you look for when selecting a product ?
A common recommendation in the market is to include a dosage rate of 1 Kg/Mt. However, the various products available may contain different concentrations of the active ingredient, like for example...

Take home message. Feed enzymes are a widely accepted and adopted means to increase feed utilisation and ultimately save on feed costs. Feed enzymes typically improve the environmental impact of animal production. While the use of phytases is most developed and widespread, there is still more to be learned and more to be gained from the application of carbohydrases and...

Introduction
Olive leave extract was effective in minimizing the oxidative stress which was induced with the advance of age, specially for plasma cholesterol, triglyceride, thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD) and glutathione s-transferase (GST). This experiment was conducted to study the effect of dietary olive leave powder (OLP) on performance, immunological and biochemical...

Footpad dermatitis is a common problem in poultry. Severe cases of footpad dermatitis have a negative impact on animal welfare as well as on the commercial result of broiler units. The quality of the litter is unquestionably a major impact factor on the development of footpad dermatitis. A combination of wet litter and unspecified chemical factors in the litter are thought to be the major cause of the footpad dermatitis. Beside...

Introduction For several decades, the use of sub-therapeutic levels of antibiotics in animal feeds has been a common practice in many countries in order to improve growth performance and prevent from the adverse effects of pathogenic and non-pathogenic enteric microorganisms. However, there are increasing concerns for the public health about the consequences from the use of antibiotics in livestock [1]. The risk of...
