Enzymes in poultry nutrition
Enzymes are proteins involved in all anabolic and catabolic pathways of digestion and metabolism. Digestive enzymes are categorised as endogenous or exogenous. Endogenous enzymes are produced by the animal and exogenous enzymes are administered from outside. Enzyme supplementation decreases nutrient loss through excreta, reduces diets nutritional levels, improves nutrient availability; thus, enhances production efficiency and profitability. In addition, exogenous enzymes hydrolyse non-starch polysaccharides, increase the usage of feed energy, reduce negative impacts of non-digestive residues on digesta viscosity, and improve gut microbial ecosystem. Cellulase, glucanase, pectinase, xylanase, galactisidases, phytase, non-starch polysaccharides degrading enzymes, amylase, lipase, cellulase, and protease are the most common enzymes used in poultry feed.
INTRODUCTION Feed cost accounts for approximately 60 to 70% of total production cost in the egg industry (Wilkinson, 2018). Out of this, 85% correlates to the energy and protein content of the laying hen diet (Santana et al., 2018). While reducing crude protein ( CP ) levels in diets may offer some advantages for the environment and reduce the feed cost, maintaining the birds’ digestive health and development performance is difficult. With the addition of synthetic...

In 2022 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 181 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. Results: 181 feed samples collected, and 92% were contaminated with DON and 80% contaminated with Aflatoxins ( table 1 ). The maximum concentrations of...

Introduction The poultry industry has experienced unprecedented growth in the past 70 years due to improved genetics, nutrition, housing, water quality and veterinary care driven by post-WWII consumer demands (Havenstein, et al., 2003). Modern-day poultry efficiently convert feed to meat and eggs, but genetic selection for improved performance may have inadvertently selected for a negative correlative response to other traits such as immune function (Cheema et al., 2003). The reader...

A study was conducted to evaluate form and dose effect of a newly developed thermostable xylanase (CIBENZA® XYLAVERSE®, Novus International, Inc.) on growth performance, digesta viscosity, intestinal weight, and digesta xylanase activity of broilers fed wheat based diets. The study consisted of 6 dietary treatments: positive control, negative control with 100 kcal/kg less ME, granulated xylanase 250 and 500 U/kg, and liquid xylanase 250 and 500 U/kg. Each...

The overuse of antibiotics has led to the development of antibiotic-resistant bacteria in poultry production. However, there are some additives, like probiotics and prebiotics, which can be used as alternatives to reduce the need for antibiotics. In that sense, how can we determine if feed additives are helpful for birds? Simply put, maintaining a healthy gut is crucial for the overall well-being of poultry, since it leads to better growth and immunity. That means that developing models to...

I. INTRODUCTION A number of factors including the global population growth, shift towards high protein diets, finite land availability for crop production, climate uncertainties, increase in fossil fuel prices and diversion of feed ingredients, especially of cereals, to biofuel manufacture presents challenges to the global feed supply. This is a major threat for sustainable poultry production, in both the developing nations, as they move towards animal protein food regimen due...
