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.

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...

I. INTRODUCTION Right now, there are two different models of production in the world and they are based on the income of the people. We have 7% of the population that lives on more than US$50 per day (Pew Research Centre, 2015) and the percentage of food expenses is a minimal part of their income. These rich countries are moving towards production where cages are banned and the birds need to be provided with space outside of the barn. However, 71% of the world population lives...

Sustainable solutions for hygienic feed production are increasingly important as the antibiotic-free/no antibiotics ever (ABF/NAE) trend becomes stronger and more widespread. Once only considered in the most mature and advanced markets, today ABF production is a regular discussion point in all regions and will eventually become a reality for smaller and developing markets. Evolution of the market – consumer and industry ABF production places ever-increasing pressure...

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....

Water is important for the overall health and performance of birds, yet less focus has been on water compared to the other nutrients. Increase or decrease in water to feed intake ratio (WI:FI) indicates issues related to nutrition, health or management of the shed particularly in broilers due to their fast growth. An automated water measurement system was developed at the University of New England to measure water intake in broilers. This system was used to measure water intake in two...

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...
