I. INTRODUCTIONExogenous phytases increased apparent ileal digestibility coefficients of 17 amino acids by an average of 4.13% (0.833 versus 0.800) in one meta-analysis (Cowieson et al., 2017); however, the scale of responses varies. Phytases increased apparent ileal digestibility coefficients of 16 amino acids by averages of 12.7%, 7.24% and 9.15%, respectively, across three selected assays (Amer ...

IntroductionPoultry scientists have long discussed and debated how the energy values of feed ingredients should be expressed (Zuidhof 2019). Pesti (2024) suggested that it is time for a paradigm shift in the way feed ingredient nutrient contents are described, and labeled the new categories collectively the Armidale method (see Fig. 1 for examples). He also proposed expanding the net energy (NE) t ...

BETAINE CAN NOT REPLACE METHIONINENutritionists constantly seek opportunities to reduce diet costs while maintaining optimal animal performance. When ingredient prices rise, nutritionists search for ways to reduce their use or replace them with alternative ingredients.With respect to methionine (Met), it is sometimes claimed that supplemental betaine (BET) has the potential to replace a substantia ...

Due to the vast expansion of poultry industry challenges also increases. One of them is the control of microbial population which is done by excessive use of therapeutics antibiotics and AGP’s. The indiscriminate use of these products results in the emergence of antibiotic resistance. Apart from resistance it also leads to public health concern. Due to this EU has banned the use of AGP&rsquo ...

CURRENT FEEDING PRACTICES INCLUDING VEGETARIAN DIETS ARE MISSING CREATINEThe poultry industry is feeding less animal protein to broilers and turkeys today compared to just a decade ago. The use of animal protein was banned in livestock feeds in the year 2000 in Europe due to concerns over public health. The complete ban was lifted, but animal protein use remains low.Animal protein products, especi ...

Tryptophan, Serotonin & MelatoninTryptophan (Trp) is an essential amino acid (AA), which is the building block of protein, therefore it cannot be synthesized by the body itself and must be obtained through food; it is important for many metabolic functions.Trp supplementation improves broiler performance through increased body weight gain, reduced feed intake and improved feed efficiency. As a ...

In the 21st Century, the poultry industry has risen to the challenges of growing animal protein demand to feed a hungry world. More emphasis than ever before is now placed on global food security. The demand for poultry meat and eggs, produced under high animal welfare standardsis increasing. Consumer of  21st Century is more vigilant to food quality and to make right choice and preference of ...
