INTRODUCTIONThere has been a substantial global expansion in egg production by the layer industry as the volume of egg production has increased by 119% (35.5 vs. 76.8 million tonnes) from 1990 to 2018 (http://www.fao.org) (Food and Agricultural Organization of the United Nations, 2018). This growth represents an average annual increase of 2.84%. China produced 458 billion eggs in 2018, and the USA ...

1. IntroductionThe conversion of dietary protein and amino acids into the protein of chicken-meat is indeed a dynamic process. Quite typically, broiler chickens attain a live weight of 2.918 kg at 42 days post-hatch and a carcass weight of 2.151 kg following processing. This translates to 376 g of carcass protein as a Ross 308 broiler carcass contains 175 g/kg protein [1]. Broiler chickens consume ...

I. INTRODUCTIONThe concept of “fast” and “slow” proteins in human nutrition was enunciated by Beaufrère et al. (2000) and consideration has been given to protein and starch digestive dynamics in poultry by Liu and Selle (2015). However, the digestion rate of protein has a greater bearing on broiler growth performance than that of starch (Liu et al. 2014). Thus, the o ...

Dietary fat and oil are potential alternative energy sources for fast growing broiler chickens (Meng et al., 2004). Nevertheless, hampered fat digestion and absorption were reported in young broiler chickens with incompletely developed digestive tract (Al-Marzooqi and Leeson, 2000). Addition of emulsifier and lipases to a diet is one strategy to improve energy utilization and subsequent growth per ...

Dietary energy is vital in animal nutrition as it is a major cost component in animal diets. Dietary fat and oil contribute high levels of energy into the diet, and different fat types affect growth performance of fast growing broiler chickens (Meng et al., 2004). Furthermore, decreased fat digestion and absorption were reported in young broiler chickens (Al-Marzooqi and Leeson, 2000). Addition of ...
