Enzymes in swine nutrition
Enzymes are active proteins that accelerate the breakdown of specific feed components to release nutrients for digestion and absorption. Enzymes are typically used in swine diets to degrade feed components resistant to endogenous enzymes, inactivate antinutritional factors, and supplement endogenous enzymes that are not present in sufficient amounts.
Enzymes typically have designations with the suffix “ase” and are commonly produced by bacteria, fungi, or yeast. The most commonly used enzymes in swine diets are phytase, carbohydrases, and proteases (Jacela et al., 2009b). Phytase is certainly the most widely used among the enzymes due to its efficacy in releasing phosphorus from phytate.
Supplementing exogenous enzymes in pig diets is an alternative solution to increase dietary energy and fiber digestibility to improve pig production performance at a low production cost and to reduce environmental impact with lower N and P excretions. The production stage, diet composition, enzyme source, amount and number of enzymes added, are factors to consider before using them.
Phytases and Mannanases are commonly used at weaning and growing stages. Xylanases and Proteases have been reported to be used in all production stages. However, the highest yielding enzymes at weaning, growing and finishing stages were Phytases and Mannanases. Dietary supplementation of exogenous enzymes improves production characteristics at all stages of production.
Introduction Enzymes have been used in livestock production for more than 20 yrs, especially in diet containing cereals with high levels of soluble non-starch polysaccharides (NSP) such as wheat, oats, barley and rye (Yin et al., 2000a, 2000b, 2001c; Yu et al., 2007). In recent years, however, enzymes have also been accepted by the industry for corn-based diets in both poultry and pigs (Fang et al., 2007; Olukosi et al., 2007;...

There are many factors that impact enzyme feed additive effectiveness and results, one of the most important of which is enzyme stability, meaning the ability of the enzyme to maintain its activity level during both feed processing and animal digestion. Intrinsic stability characteristics are encoded in the molecular structure of an enzyme by its amino acid sequence which...

The global swine industry adopted early-weaning practices a generation ago. However, early weaned piglets have been characterized by poor growth performance, known as the “postweaning lag.” A transient hypersensitivity response to new exposure to soy protein is one reason for the lag in post-weaning growth performance. Soybean meal (SBM) is commonly used as the primary protein source in pig diets. While some of the proteins in SBM are more easily...

The global swine industry adopted early-weaning practices a generation ago. However, early weaned piglets have been plagued by poor growth performance, known as the “post-weaning lag.” One cause of this is the piglets’ hypersensitivity to soy protein – specifically glycinin and β-conglycinin, which make up about 40% and 30% of the total protein found in soybean meal (SBM). These proteins have been found to be allergenic to the intestinal lumen, leading to...

1. Introduction Wheat is one of the most variable in composition among cereal grains (Choct et al., 1999a). These differences are exacerbated by the environmental conditions under which the grains are grown (Longstaff and MacNab, 1986). A review by van Barneveld (1997) using past data for more than 70 cultivars of wheat found differences of up to 3.7 MJ/kg dry matter (DM) in digestible...

Introduction
Inclusion of high levels of byproducts can reduce diet cost but tend to also decrease growth performance due to low nutrient digestibility. Dietary enzyme supplementation may be a viable solution to increase byproduct inclusion while maintaining growth performance.

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...

In today's efficient conscious world, we save on anything and everything including communication. One of these is abbreviations. Recently I stumbled across one, which I called WAAW! Translation? War Against Amino Wastages! Amino wastages are unnecessary biological losses of amino acids, especially critical ones like methionine, lysine and threonine. In this war the call is to adopt a zero waste policy, doing this will recover more cost as amino acids are among the most...

The interest of using probiotics to reduce the use of antibiotics in pigs
Suggested link
In 1921, Alexander Fleming discovered the antimicrobial powers of the enzyme lysozyme after observing diminished bacterial growth in a Petri dish where a drop from his runny nose had fallen. The famed Scottish bacteriologist published his findings a year later, but ultimately decided that the enzyme didn’t meet his criteria for a useful antibiotic—unlike penicillin, a later discovery.
Lysozyme, Fleming showed, is...

Introduction The feed enzyme market today is worth approximately $1 billion USD and is dominated by NSP’ases and phytases, with proteases also playing a minor but significant role. The principal reason for their employment is that they improve digestibility of a number of nutrients, specific to the enzyme employed, and as a result enable the use of less digestible, cheaper and most frequently more...

Introduction In recent years, the cost of energy for feed has increased, with increasing demand for cereals from the biofuels industries. It follows that there is currently pressure on feed manufacturers to maximise their efficiency of nutrient utilisation, particularly of energy but also phosphorous. The net result is that feed manufacturers are moved to consider use of feed additive enzymes such as xylanase for...

Enzymes are now widely used in animal feed. Various key reasons justify their use. Firstly, enzymes inhibit the action of anti-nutritional factors in the feed, which have an adverse effect on both the animal's digestive system and health. Secondly, enzymes improve access to the nutrients in the feed. Lastly, enzymes compensate for the lack of natural enzymes capable of breaking chemical bonds as well as the lack of enzymes in the undeveloped...

Introduction
Swine diets are normally digested at about 85% efficacy and dietary proteases may be used to increase the efficiency of protein digestion and reduce cost. In addition, fermentation of undigested protein increases hindgut pH making the environment more favorable for the proliferation of opportunistic pathogens.

Phosphorus-based nutrient management regulations increase the amount of land required to dispose of manure and will have a detrimental effect on pig farm profitability in areas of intensive animal production. Decreasing the phosphorus content of manure through nutrition with phytase is a powerful and cost-effective approach to reduce the amount of land required for pig production and therefore reduce the cost of manure disposal. ...
