Improving feed efficiency (FE) reduces the environmental impact and increases the profitability of pig production. Despite the improvements in pig FE achieved in recent years 1,2 , it still takes~3.5 kg of feed to produce 1 kg of saleable pig meat 2–4 . Nutritional strategies can be implemented to improve FE; however, the impact of these strategies on the microbial composition of the gastrointestinal tract (GIT) is seldom explored. This is surprising given...

Introduction Minerals make up a small but vital percentage of swine diets with profound impacts on animal health, growth performance, feed cost and the general environment. Calcium and phosphorus are the two most abundant minerals in the body, and they exist largely (about 98%) in the form of carbonated hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) in the skeleton (Mahamid et al., 2010). They are required for a wide variety of functions...

Introduction In practice, an optimisation program is used to formulate commercial diets to meet the minimum nutrient constraints in order to minimise feed costs. With phytase, potentially unjustifiable high contributions will result in reduction of safety margins or even lead to nutrient and energy deficiencies with a negative impact on animal performance. When applying values, it is important to understand that it is not possible to compare matrices from different phytases...

Introduction Phytases of bacterial origin are the exogenous enzymes most widely used in the diets of monogastric animals, acting on the hydrolysis of phytate (myo-inositol 1,2,3,4,5,6-hexakis [dihydrogen] phosphate) to release the phosphate from this complex [1,2]. Phytases are commonly developed by means of genetic engineering [3], such as phytase from Escherichia coli expressed in Trichoderma reesei and phytase from Citrobacter braakii expressed in Aspergillus oryzae [2]. They...

Distillers dried grains with solubles (DDGS) has a high concentration of Leu, and the Trp requirement for growing pigs may be increased if diets contain excess Leu. Therefore, the objective of this experiment was to determine the optimum standardized ileal digestible (SID) Trp:Lys ratio in growing pigs fed diets with excess Leu from DDGS. A diet based on corn, soybean-meal, and 35% DDGS was formulated to be deficient in Trp and Lys, according to NRC requirements (0.13% SID Trp;...

Introduction: The application of enzymes in swine nutrition has gained traction over the past several years. Exogenous enzymes have become an integral part of commercial poultry feed for enhancing the efficiency of nutrient utilization, thereby reducing the cost of production, and improving growth performance. In swine, the application of exogenous enzymes is not yet a common practice, which demands for nutritional matrix validation and further investigation for each type of...

The growth graph of the global animal feed enzymes market is expected to display an upward trend in the coming years, due to the increasing preference of the people for nutritious diet along with a considerable rise in the disposable incomes, especially among the developing nations. In a report by the Government of Australia, the global consumption of meat increased to reach 360 million tons in the country by 2018.
With an evident increase in the consumption of animal by-products,...

Functional amino acid supplementation during disease challenge enhances growth performance and immune status. The present study investigated the effect of duration of adaptation period to a functional amino acid (FAA)-supplemented diet on growth performance and immune status during a subsequent Salmonella challenge in pigs. Thirty-two mixed-sex weanling pigs (8 pigs/treatment; 11.6 ± 0.34 kg initial body weight) received either a basal diet without FAA supplementation...

The intestinal morphology can be compromised in pigs when exposed to heat stress (HS), partly due to increased production of reactive-oxygen species. Because methionine (Met) functions as intracellular antioxidant, requirement of Met may be increased in HS-pigs. The effect of dietary supplementation with DL-Met above requirement on performance and serum concentration (SC) of free AA in HS-pigs was evaluated. A basal wheat-soybean meal diet was formulated to meet 100% Met requirement...

Introduction Voluntary feed intake is often low and variable directly after weaning. As a result, research has focused on how nutritional stressors can be overcome to stimulate feed intake and subsequently increase performance (Pluske et al., 1997). Thus, highly palatable and nutrient dense protein sources are commonly added to nursery diets to encourage feed intake. Traditionally, this has been accomplished with the addition of milk and animal-based by-products. However,...

Fermentation products with main and side activities Feed enzymes are mostly produced by fungi or bacteria. Those living organisms produce a wide variety of different enzyme proteins. For commercial practice, only a limited number of those activities is assayed in the laboratory. Assaying e.g. the xylanase activity obviously results in a quantification of the xylanase level, while not providing information about other activities that remain present in the fermentation product. In...

Introduction Protein is a major and expensive component of animal feed, accounting for about 20% of the total dry matter content of swine and poultry diets. Soybean meal is the leading source of feed protein [ 1 ]. In the gut, protein is hydrolyzed by endogenous proteases, principally pepsin (EC 3.4.23.1), trypsin (EC 3.4.21.4) and...
