To provide in vitro evidences on the antimicrobial effect of yeast cell wall (YCW), the effectiveness of YCW fractions in inhibiting the growth of several C. perfringens strains was quantitatively determined. The bacterium was grown in the presence of different YCW fractions at different concentration levels. The effect of YCW fractions on the growth parameters was analyzed. One product out of four materials was selected as the best candidate for C. perfringens ...

Dr. Andreas Lemme, Director of Technical Consultancy, answers the question: what hinders or limits protein reduction today? “Firstly, one needs to have good knowledge about the composition and quality of feed ingredients. Technologies are available to quickly get the required information. In the context of amino acid nutrition, we have developed near-infrared spectroscopy calibrations to get the full analysis of ingredients within seconds..."...

Researchers from Spain and the Netherlands performed a study to determine if adding a mineral and vitamin mix (AHS and Vitamin C) would have an effect on broiler performance in heat-stressed conditions.
1,824 one-day-old birds were randomly allocated to 48 identical pens of 38 birds each. All birds were equally fed a 3-phase feeding program. There was no variation in feed throughout this study.
The control group(s) were...

Guanidinoacetic acid (GAA) as a source of creatine. 1. Creatine is a naturally occurring component in the body of animals and is a critical component in energy metabolism. 2. In contrast to other nutrients, creatine is stored in the muscle and directly reloads ATP for energy supply to the muscle. This is particularly important during periods of high energy demand and prevents the formation of reactive oxygen substances which have a negative effect on performance. 3....

Poultry is a homothermal animal, and its body covers with feathers to increase its cold resistance. However, Taiwan is an island that lies in the tropic of cancer, and the general climate is marine tropical. During summer, this mechanism is adverse to heat dissipation and causes heat stress. Heat stress is a familiar stress effect that will affect animals’ growth performance, productivity, and health. Heat stress affects livestock production results in increased demand for net...

Introduction Quail farming is very important for providing jobs and producing high quality protein at a low cost. Nutrition during the growing phase of the birds can influence their performance during the production phase. Most research has focused on the nutritional requirements of quails during the laying phase and there is little information about requirements during the growing phase. Quails are characterized by early sexual maturity (40 days), demanding feeding programs...

Over the past decades, genetic improvements have stimulated broiler production resulting in birds weighing ± 3kg in 42 d. To reach this genetic potential, the absorption and digestion of nutrients and according morphological and functional development of the small intestine in the early life must be impeccable. Before hatch, uptake of nutrients by the chicken embryo is limited but rapid increase in villus length and formation of intestinal crypts, have been reported close to hatch and...

This study investigated the effects of Bacillus -based probiotics on performance and intestinal health in broiler challenged with Clostridium perfringens -induced necrotic enteritis. One-day-old Arbor Acre (n=480) were randomly assigned to four treatments with 10 cages of 12 birds. Dietary treatments were; basal diet negative control (NC), with no probiotics nor antibiotics formulated to contain 2,930 and 3,060 kcal/kg with 24.1 and 16.0% CP, for starter and finisher diet,...

High-shear dry extruded corn and soybeans and the quest for higher growth performance in modern broiler genetics. Feeding young broilers during the first 10 days post-hatch is the new frontier in poultry nutrition. The same holds true for any effort to boost life-time growth performance in modern genetics through nutrition. Research and commercial experience have shown that it is possible to boost overall growth performance by...

Poultry production programmes require elimination or reduction of the use of in-feed antibiotics growth promoters (AGP). This has led to an increase in the occurrence of necrotic enteritis, making it an economically significant poultry disease requiring an alternative nutritional interventions. Probiotics offer one alternative to AGP because they can elicit specific actions that promotes the development and maintenance of a stable gut microbiome, leading to a reduction in enteric disease and...

1. Introduction Similar to mammals, the liver in birds is involved in an array of metabolic and homeostatic functions and considered as a biochemical factory responsible for most of the synthesis, metabolism, excretion, and detoxification processes. It plays an important role in digestion and metabolism, regulating the production, storage, and release of lipids, carbohydrates and proteins [1]. The liver produces a variety of proteins, including blood proteins, enzymes, hormones,...

INTRODUCTION The huge increase in poultry production to meet the growing demand in Nigeria has led to the rise in antibiotic use, leading to a worrying increase in cases of antibiotic resistance diagnosed in animal and humans via direct contact, environmental contamination and food consumption, causing high cases of cancer and other ailments. According to NCI (2012), over 100 types of cancers affects humans, this negativity prompted the European Union (2006) to recommend other...

INTRODUCTION In China, Spain, Italy, Mexico and Peru, amongst other countries, the consumer demands chicken with yellow skin pigmentation. Since skin pigmentation is associated with health status and product freshness (Breithaupt 2007, Liu et al 2008, Hernandez-Velasco et al 2014), there is a large volume of whole chicken or parts commercialized with the skin (Baker and Günther 2004). The inclusion level of dietary pigment for broiler chickens...
